LED bulbs are the next big thing when it comes to flashlights. LED flashlights can cost hundreds of dollars, depending on the kind of LED bulb used. However, you can make your own ultraviolet LED flashlight for far less. Be aware, however, that once your friends see it, they may want you to make them one also.
Preparation
1 Find an ultraviolet LED (Light Emitting Diode) from your local electronics store or online.
2 Purchase a 1/4 watt 100 ohm resistor. This also should be available at your local electronics store or online.
3 Buy a flashlight that requires up to 4 1.5 volt batteries to run when making your own ultraviolet LED flashlight.
4 Remove the bulb from the flashlight you purchased. You may have to use a scissors clamp to remove the bulb from the flashlight without breaking it. Be sure to grasp the bulb by its metal collar, and gently pull the bulb up out of its setting.
5 Hold the bulb by its collar with the scissors clamp, and heat up the base of the bulb with a soldering iron. Make sure you use eye protection as you do so.
6 Wait for the solder to cool, and then tap the scissors clamp, as it’s still holding the bulb, against your work bench. You may have to do this rather sharply. By tapping the scissors clamp in this manner, you dislodge any melted solder from the LED bulb. You can choose to use a solder wick instead of tapping the scissors clamp against the workbench and achieve the same result. Basically, you want to get rid of any excess.
Creation
1 Check the bottom of the bulb to see if you made a small hole in the bulb’s base when making an ultraviolet LED flashlight.
2 Solder the 100 ohm resistor to the positive lead on the flashlight you are using to make your own ultraviolet LED flashlight.
3 Bend the shorter negative lead on the LED about 90 degrees. It should extend away from the LED base.
4 Shorten the lead that’s the longest by clamping a pair of scissor clamps. The clamps should rest against the LED. Clip off any excess of the lead, leaving only a little protruding beyond the scissors clamp. Shorten the leads on the 100 ohm resistor so they’re up to inch long.
5 Attach the 100 ohm resistor to the positive lead by soldering it. You can use the scissors clamp as a heat sink as you do this. Do not allow the solder to flow for more than two seconds.
6 Insert the longer lead through the base of the LED bulb and through the hole you created.
Assembly
1 Make sure you put the LED bulb in a position that’s as close to the original flashlight bulb when you create your own ultraviolet LED flashlight.
2 Let the resistor’s free lead keep its 90-degree bend, and allow it to drop into a slot on the base’s side and into the solder.
3 Keep the LED bulb centered, then bend the resistor’s lead down so it’s now pointing toward the base’s bottom. Bend the other lead so it’s now sticking out of the base at a 90-degree angle.
4 Utilize rosin flux to solder the negative lead to the solder on the side of the base when you’re making your own ultraviolet LED flashlight. Remove any excess of the lead that remains. Solder the bulb’s base to the lead that’s extending to the base, and remove any excess.
5 Check to make sure no portion of the lead extends beyond the outer walls of the bulb’s base. You may have to bend the leads to ensure this. You can make the leads flat against the bottom of the base. This will also serve as your bottom contact when you are making your own ultraviolet LED flashlight.
6 Put in the new LED bulb into the flashlight. You can make sure there’s enough room for the batteries by wrapping cloth around a dowel that’s the right size and making sure it fits inside. Insert the batteries and enjoy. You have just created an ultraviolet LED flashlight.
Business Lighting Solutions has partnered with Schneider Electric to install LED-based retrofit lamps for T8 fluorescent fixtures at an Air New Zealand facility delivering more than 50% energy savings.
Business LED Spotlight Solutions (BLS) has reported that its LED-based Ecofluro T8 tubes have been used to replace more than 2100 fluorescent tubes at an Auckland, New Zealand facility that houses Air New Zealand’s engineering operations. Schneider Electric partnered with BLS on the solid-state lighting (SSL) retrofit that Schneider projects will deliver greater than 50% energy savings.
Replacing fluorescent tubes with LED-based tubes has remained a popular concept due to the sheer number of such lamps installed globally. BLS sales director Paul Stoddart said, "Fluorescent bulbs, which are used by most New Zealand businesses, contribute to around 40% of the average office power bill so by replacing them with LEDs a business can literally halve this cost."
Still, LED-based retrofit lamps haven’t proven capable of producing the same level of light output that the latest fluorescent tubes produce according to numerous US Department of Energy (DOE) tests. In May 2011,the DOE published a detailed report of LED T8 tests in a typical office environment. The results found the SSL products draw less power, but also provide less light on the task plane due in part to the fact that the directional daytime running light sources aren’t a good match to the troffer fixtures designed for omnidirectional fluorescent tubes.
Photometric data
BLS published photometric data on its website that would indicate the Ecofluro tubes produce greater light output than do the products that the DOE has tested. The summary test data on the company’s website is ambiguous, but the detailed report states that a single tube produces 2032 lm. That value is calculated based on intensity measured at 5° increments around the lamp. The LED tube T8s tested in the DOE study produced 1366 to 1539 lm.
The DOE report concluded that T8s would be a viable retrofit choice in applications where an area was overlit. When asked about the relative lighting before and after the New Zealand retrofit, LBS design and technology director Chris Wheatley said "The light projected on the working plane is +/- 2-5% depending on the color temperature and type of fitting."
BLS is also reporting significantly higher efficacy than DOE tests have documented. The photometric documents on the company’s website indicate a lamp efficacy that’s over 100 lm/W and system efficacy near that value with some fixtures. A look at the DOE reports show a maximum bare-lamp efficacy of 93 lm/W with significantly-lower system efficacy.
When asked if the DOE had tested LED display products, Wheatley said, "No, to our knowledge they only tested American products and we were not involved. The efficacy of the products tested that I saw were around 70 lm/W whereas we are achieving closer to 100 lm/W. Again this is referenced in the NATA (National Association of Testing Authorities, Australia) accredited photometric reports provided."
LEDs America T8s
BLS isn’t the only LED T8 maker specifying better light output and efficacy than DOE test have revealed. For example, LEDs America claims that its SSL T8 tubes deliver 1400 directional lumens while consuming only 14.6W.That’s close to 100 lm/W efficacy. LEDs America and its sales and distribution partner Viper Networks have announced increased production of the LED bulb products over the next two quarters.
The T8-retrofit market will surely continue to draw the interest of lamp makers and electrical contractors as a significant business opportunity. Moreover, as LED T8s continue to improve, the technology could deliver significant global energy savings.
In this world of growing environmental awareness, the quest for efficient LED bulbs energy is growing continuously. A lot of businesses and people are in search of lighting options that will not only reduce energy consumption but also cost efficient and highly functional. LED tube lighting may possibly be the solution most consumers are seeking.
LED spot light lamps stands for light emitting diodes. They are minute semiconductors chips that transform electricity into light. The earlier incandescent lighting bulbs create light as a secondary output from the intensely heated filaments that require a lot of energy. On the other hand, LEDs convert the energy flowing through them into light thus can be efficient two times more than the incandescent light.
The latest technological advances in fluorescent lighting have direct to recognition of compact fluorescent lights among people. LED lighting is however more proficient because it can last over seventy five times than incandescent light and more than eight times than fluorescent lights. LED flashlight is presented in various colors that create various kinds of effects in an area. When one is selecting the correct LED lighting either for the office or for home installation, he or she should consider the level of lighting needed in that room. This is due to numerous levels, which can generate a bright glow or soft feel in a row.
LED street light generally, are made with the use of a long silicon substrate, which has some LEDs. The substrate is normally enclosed in a glass tube, which makes it ready for use. These tubes have no toxic gases or chemicals hence can be disposed as common waste.
There are major health and environmental hazards, which are associated with the incandescent and fluorescent lights due to the presence of mercury, which is very dangerous and toxic. Those who have ever worked in warehouses and office where fluorescent tubes are installed know well about the irritation and distraction of the flickering lights that causes vision and eye problems.coloured LED bulbs alleviates such flickering because with time, they lose their luminosity but still have great output.
When the compact fluorescent light bulb (CFL) became popular a few years ago, it was a welcome alternative to the toxic, energy-sucking incandescent bulb used around the world.
Torch light, alternative to traditional fluorescent and incandescent lighting, will be occurred in television in the field of LED backlighting on the fluorescent lamp (CCFL) in the substitution process which can be found in CCFL backlight LED price difference relative to the fastest period of decline; there is a rapid penetration rate of LED backlighting rise time.
In LED strip light manufacturer products with the traditional lighting products during the rapid decline in the price difference, LED lighting penetration will increase rapidly. In the LED industry, there is a proposed by the Agilent RolandHaitz Haitz law, is considered the LED industry, Moore’s Law.
LED commercially since the cost per lumen decreased by about 20% per year, and from recent data, the brightness improvement and cost reduction has accelerated the trend. According to the U.S. Department of Energy forecasts, the cost lumens white household LED bulbs package from 2009 25 $ / klm, down to 2015 2 $ / klm, the average annual cost reduction of 30% or more, while the annual average between 2010-2012 fell almost 40%. We think, 2011-2012 LED and traditional lighting will spread the fastest time down, LED lighting penetration produced during this period will increase by leaps and bounds.
According to our calculations, the lm is the unit of measurement in 2012 LED lighting costs will be reduced to about twice as fluorescent lamps, such as the relative fluorescent RGB LED strip light life span of about 2.5 times the account, will make about LED lighting in 2012 ahead of the total cost of fluorescent lighting. Therefore, we believe that LED lighting, large-scale alternative to the end of 2011, early 2012 will start, 2011-2012 LED lighting industry is important investment timing.
LED light source in the alternative on the same process will repeat this, LED lighting alternative to first in the commercial, industrial place, get a good role model, and then gradually spread to household lighting. At present the traditional lighting, including fluorescent, incandescent, halogen, HID, each general lighting revenues 36%, 23%, 16%, 13%. With the disabled in countries incandescent, fluorescent instead of incandescent lamps,SMD LED strip light incandescent and fluorescent lights on the alternative will be carried out concurrently. Because of commercial and industrial enterprises to be more sensitive to electricity costs, the government enterprises become more stringent energy conservation requirements and other reasons, commercial, industrial use of energy efficient lighting products more positive performance.
The LED strip light industry is blooming in 2011 due to the government and the growing demand for energy efficient products. And the cost of high-power LED light sources may decrease to NT$10 (US$0.35) per 100 lm/W in late 2011, comparing to NT$20 currently, which may improve the growth of LED market.
The biggest part of the costs is no longer the chips, but radiators and drives which form about 2/3 of the total cost for E27 LED Spot Light. T he decrease in price will likely to occur in the third quarter, according to Jason Wu, chairman of Edison Opto.
In order to lower costs, Wu added, the TEMO (thermal management, electrical scheme, mechanical refinement, and optical optimization) integration must be achieved. The cost of LED down light cannot be broken down in parts, it has to be examined in whole, Wu pointed out.
The prospect for high power LED spot Lights has been questionable recently for April revenues are flat compared with March revenues. However, as the second quarter is the traditional boom season, both revenues and gross margin are expected to outperform the first quarter, according to Edison. Targets announced in the investors conference at the beginning of 2011 will hopefully remain, stated Edison.
Fourth, a manual for your particular LED light may do you good. Many LED lights can simply be pulled out, but other have certain ways that they connect more securely. You will need to know what kind you are dealing with, don’t guess. Find the manual or instructions on your new bulb and remove following those directions.
Here comes the most important step — replace the old bulb with the new dimmable LED bulbs. The new bulb should go in just like the old one came out. You will want to test the light before you put the encasing back on to make sure everything works and the light is the same color. Replace the case that was over the LED lights and make sure the casing is secured tightly.
Have you finished that? Isn’t it easy? Just have a try and make your PC more attractive with the interior LED lighting. Hope you enjoy it! When mentioning Light Emitting Diode lighting technology, everybody knows it is about energy-saving and environmental friendliness. Compared to incandescent bulbs, LEDs produce far more light per watt, which is useful for energy conservation, and have a much longer lifespan. Indeed, such advantages are reflected on your utility bills. Besides, high brightness LED is mercury-free and non-radiative, posing no threats to the environment.
Since high power LED bulbs are widely used in different fields, they can also be used in home. A proper can bring you a lot of convenience. But how to select a proper LED flashlight is not that easy. Here are some tips which may give you some advice.
Check out the battery life for each LED flashlight in which you are comparing. There are many activities and situations where a quality flashlight might be helpful or even necessary.white LED strip light tend to have multiple light settings, such as low, medium and high, so you should compare the battery life at each of these settings. When considering which flashlight to purchase, one of the main factors should be energy efficiency. The LED flashlight packaging or product description should include a battery life chart.
Pay attention to the indicated effective range for each LED flashlight. The more efficient a flashlight is, the more dependable it is because the batteries will last much longer than inefficient models. Again, this could vary depending on the light setting. Knowing what activity for which you’ll be primarily using the flashlight can help you determine the minimum indicated effective range that you will need.flexible LED strip light, for example, are very efficient and the batteries tend to last much longer than other types of flashlights, such as those that use incandescent bulbs. For example, if you plan to use the flashlight while camping, you will most likely be looking for the longest range you can find so that you can see in front of you while walking through the woods.
Research the pros and cons of replaceable versus rechargeable battery flexible SMD LED strip light. When deciding which LED flashlight to choose, it’s important to compare all of your options. The rechargeable battery models tend to cost more and the batteries can be harder to come by. Some consumers prefer putting the extra money into a more powerful LED flashlight that takes standard replaceable batteries that are easier to find. Shake flashlights are also a possibility.
Since you have known some features of LED flashlights from the abovementioned, it becomes much easier for you to compare LED flashlights and pick up the most appropriate one. flashlight, led, lighting
A garden light diode is a semiconductor device that emits incoherent narrow-spectrum light when electrically biased in the forward direction. This effect is a form of electro luminescence. LEDs are small extended sources with extra optics added to the chip, which emit a complex intensity spatial distribution. The color of the emitted light depends on the composition and condition of the semi conducting material used, and can be infrared, visible or near-ultraviolet. Rubin Braunstein of the Radio Corporation of America first reported on infrared emission from gallium arsenide and other semiconductor alloys in 1955. Experimenters at Texas Instruments.
LED lights actually light-emitting diode light bulbs. This technology is really not a new one because it had been developed around 1970s. However, it is just these past few years that LED lighting has become popularized. Some argue that LED light bulbs costly as compared to an incandescent light bulb. What they do not know is that LED lights may cost a little more than an incandescent bulb but it can help them save electric energy, which means, their electric bill will be much lesser if they replace all they light bulbs to LED light bulbs.
As it has been pointed out,LED light is way cheaper than incandescent lighting. This is because LED lights are more efficient than its counterpart. To explain further, LED lighting uses around 80% of its electrical energy and converts it into light energy, which the consumer can enjoy up until 10,000 hours. This means that LED light bulbs can last for more than a year! This is very beneficial than an incandescent light bulb, which just lasts for a few months. Apart from the incandescent light bulbs short life span, it also uses more wattage for it to work but it only uses 20% of its electricity into light energy. This means that, incandescent light bulbs use up more electricity to give off light but it wastes about 80% of its electricity to heat, which is lost in the room.
Apart from LED bulb being cost and energy efficient, it is also complementary to the building’s architecture. There are a lot of manufacturers that are designing LED light bulbs which is artistic so that it will not ruin the beauty of the building. Not only that, there are also a lot of LED lighting that a consumer can choose from, which ranges from red, blue, green and white light. Thus, it can not only function for general lighting but also, LED light bulbs can be used in theater, outdoor, and even underwater! Thus, there is no reason to stick with the old school incandescent light bulb. So what are you waiting for, replace all those boring bulbs to LED light bulbs.
Place your LED panel along the edge of your coin battery so that the terminals straddle either side of the battery. When pressed against the battery, the LED should light up. LED pens, featuring a bright LED in place of the ink tip, are useful due to their portability and small size, making them the darlings of electricians and automobile mechanics. If it does not, rotate the battery 180 degrees.
Drop the glowing LED into the end of your highlighter pen. Wrap a small piece of electrical tape around the LED terminals and coin battery. Remove the end cap and separate the battery from the LED when you are not using your new pen. The flat sides of the pen allow the wide coin battery to slide in.
The solar street light will protrude from the tip of the pen, offering its bright glow in the direction of your choosing. Shake your highlighter. If the LED and battery bundle moves around inside your pen, shove a few sheets of tissue into the end to hold everything in place. Use a more powerful coin battery to make your LED grow even brighter. Place the end cap on your highlighter when your pen is not in use.
