I’ve been thinking to show people some interesting stuffs about LED lights, eg. LED light source, LED lighting fixtures, LED light components etc. In a series of articles (this one would be the first post, and there will be some other followed up), I will demonstrate some typical LED light bulbs by using some diagrams and annotations. Now just let’s start by one of the most commonly seen globe LED light bulbs: E27.  See Fg.: LED Light Bulbs E27

 

LED E27 Light Bulbs

From the appearance point of view,  globe LED light bulbs and traditional incandescent bulbs look very similar. However, in fact, the difference between them is tremendous.

Globe LED Light Bulbs E27

Light Source: light source is the essential difference between LED light bulbs and traditional incandescent bulbs, and that’s the reason why LED lights are much more efficient than incandescents. Rather than using tungsten wires, LED light bulbs adopt LEDs (Lighting-emitting Diode) as light source.

Materials: materials are different, LED Light bulbs usually adopt mist glass and aluminum, while incandecents usually adopt transparent glass and plastic. Reasons for that: LEDs emit very strong directional light (spot light), with transparent glass, the light would be too harsh to make people feel uncomfortable.  Therefore, it needs diffusion treatment – defused lens.

Driver: furthermore, LED light bulbs need drivers (or transformers) in order to be running in 110V or 240V high-voltage fittings, while the traditional incandescent light bulbs do not.

The picture below illustrates a typical globe LED light bulb exploded view. The light bulb is decomposed into 9 parts as can be seen from the diagram. The following are the corresponding annotations.

Do you know broken energy-saving lamps harms?

Nowadays, energy-saving lamps are increasingly replacing the traditional incandescent light bulbs, and become the most environmentally friendly lighting choice. To achieve their emission reduction targets, the EU is to phase out traditional incandescent that has been used for 120 years. People are mandatory  to replace their low-efficiency light bulbs with energy-saving lamps. In the UK, compact fluorescent (CFL) is the most common energy-saving lamps. Germany, however, warns the public based on a new study: the mercury released by broken energy saving lamps will be a risk to health, especially for infants and young children and pregnant women. While, LED lights, traditional incandescents, and halogen light bulbs will not cause such problems when broken, because they do not contain mercury.

German Federal Environment Agency claimed that, according to the new research, the mercury toxity of broken energy-saving lamps can be 20 times excess of interior safty guidelines’ standards. GFEA’s Board Secretary said that the presence of mercury in CFL energy-saving lamps is a major defect, therefore, new technologies are need to be adopted as soon as possible to prevent mercury pollution.  The advantage of 80% energy saving and safty of CFLs ought to be synchronous development. A council spokesman said that children and pregnant women should stay away from broken CFLs. In those places with children and pregnant women activities, protection lampshades are suggested to be installed to prevent mercury release by broken energy-saving lamps.

However, the British government insisted that the mercury risks of energy-saving lamps is over-concerned. Broken CFL bulb mercury hazard in fact is some occasional cases, not a big deal. UK Department for Environment, Food and Rural Affairs spokesman claimed that, the mercury containing in the CFL energy saving light bulbs is insufficient of harming the surrounding populations.

City of Baytown Made a LED Pilot Program

Last week, the City of Baytown, the Texas Department of Transportation and lighting manufacturer BetaLED have jointly made a pilot program on adding LED street lighting to the city.

Six conventional 400-watt high pressure sodium fixtures were installed on three light poles located on Highway 146 at the Garth Road overpass. The lights were retrofit with BetaLED's THE EDGE luminaries.

This is the first in a series of testing that will be done throughout Baytown in the months ahead, and it's expected to save the city between 65 and 80 percent on energy and replacement costs. If successful, highway lighting may be added throughout the state.

LED lights, save your bills, save our planet.

LED Lighting Facades

To illuminate the facades of buildings use special spotlights that are mounted on special brackets on the roof, walls, buildings and land.

In Russia and abroad produced many types of floodlights to illuminate the facades of buildings ranging from 35 to 2000 Watts. In the latest generation of projectors are commonly used halogen lamps and LEDs.

If you compare LED and halogen floodlights to illuminate building facades on the main characteristics, in many LEDs are absolute leaders. By quantity of light emitted by LEDs in the lead direction of the light radiation - halogen lamps lose up to 60% luminous flux. LEDs win for color purity and wide range of colors - up to 16 million colors (light filters halogen bulbs burn out quickly), ease of operation and energy savings (up to 6 times compared with halogen lamps). In addition, LEDs improve reliability and service life of lamps, as well as reduce maintenance costs (lifetime in continuous operation - 100 thousand hours).

With the help of a certain number of elements and various optical lenses LEDs allow you to create different projectors and lighting with the power required to illuminate the building. Modern control systems use light-emitting diode searchlights dynamic effects that are not available halogen lamps. The only drawback of LEDs - the high price and low unit capacity, ie for obtaining high luminous flux is required to use a large number of LEDs.

Over the past year or two, were first successful installation of LEDs in architectural lighting cities in Europe and the U.S. made the first attempts to use them in Moscow. In the city the use of LED lighting effectively, experts say that for private homes in the next few years this type of lighting would be dominant.

Hill County of USA Acquired Grant to LED Retrofit

Currently, Hill County has acquired a State Energy Conservation Office (SECO) $86,365 grant as part of the American Recovery and Reinvestment Act.

Funds were allocated to replace parking-lot lighting with solar-powered LED lighting at the Hill County Sheriff's Office on Hall Street. LED lighting will also brighten the facility outside. Besides, the sheriff's office jail on North Waco Street in Hillsboro will also get a lighting makeover. The LED lights will replace several high pressure sodium light fixtures,ten floodlights on the exterior of the Hill County Courthouse.

It was estimated that energy and maintenance costs totaling $60,000 will be saved by the county over the next five years.

The lighting overhaul, con-tracted by Solar Wind Technologies out of Allen, is expected to be completed next month.

Fujian province planed to develop the public LED light with Taiwan LED companies

It's said that China's Fujian provincial government planed to invest CNY20-30 billion (US$3.01-4.51 billion) to develop the public LED lighting market over the next five years, and jointly set up a publicly traded company with Taiwan-based LED companies.

Fujian provincial government expected to install 300,000 LED street lamps in 2011, 600,000 in 2012 and up to 1-2 million in 2013. It's estimated that the total LED street lamp market would reach 5-6 million units in Fujian.

Taiwan's Industry Technology Research Institute (ITRI) and the LED Street Lighting Industry Alliance had confirmed the report. If Fujian took the idea, Taiwan's LED Street Lighting Industry Alliance's member would have a chance to become the initial beneficiaries, such as Unity Opto Technology and Everlight Electronics and so on.
