LED lights market expected to compete more intensify with price dropping

The market estimated that Led lighting products' prices would drop by 15-20% each year amid increase competition in the market as vendors reduce prices to gain market share, which even be fall to one-third of current prices.

At first, the Japanese market appeared to price war in 2009. Sources from Led companies indicated that the price competition had extended to China, Europe and the US.

Some light bulb makers reportedly would introduce led lighting products at end-use price of US$10 in 2011, which would compete for pricing scheduled to enter the LED sector with distributors and retailers well-known, and the price battle would only intensify in the future.

City of Foley Considers Retrofitting LED Lights

It's reported that City of Foley is thinking about updating some new light throughout the city by experimenting with Led technology.

On Monday, Bravo Zulu, a technology company specializing in communications and monitoring technology have given a presentation focused on the benefits led light technology could have for the city, and ways the technology could be implemented to the city council.

According to Bravo Zulu , one of the main benefits of its LED technology is an included sensor system, which detects motion to turn the lights on when cars or people are nearby and dims the lights, using less power when no one is nearby.
So far, no decision has been made regarding the placement of LED lights in Foley, but the council is considering the possibility.

LED Light Underware, Would You Put That ON？

If I asked you, what can led lights be used for? I’m sure you’ll know the “standard answer”, which would be “led lights can be used for lighting”. Yes, I can not say that you are wrong, but I’m afraid with this answer, you could probably get an B (maybe B+, if you are lucky enough), but you would not get an A from me. Wondering why?

I always believe that, imagination is the greatest gift for mankind. Great imagination creates great things.

In this article, let our brilliant designers lead you into a dream world. These talented designers would let you know that lights are not only for decoration of buildings but are also capable of decorating human bodies, lights are not only lights, they can be clothes too. The following are some LED light clothes.

China May Come out the Restrictions to Phase out Incandescent Light Bulbs

After the EU, the US, Australia and others have imposed restrictions to phase out incandescent light bulbs, it's reported that China is in the process of making the road map for banning the use of these bulbs. The restriction is expected to be unveiled in March.

According to Wang Jinsui, director general of China Illuminating Engineering Society, said in China Business News," The National Development and Reform Commission has been drafting the map."

Wang said the initial plan is to stop producing 100-watt incandescent bulbs after 2015 and ban them completely from 2018. China has provided subsidies for using energy-saving light bulbs since 2008, prompting many incandescent bulb producers to cut their output.

Diagrams of Typical LED Spotlights: GU10

Continuing with our last post” Diagrams of Typical LED Light Bulbs: E26,E27” regarding globe E27 LED light bulbs, in this post, we will talk about GU10 LED spotlights.

 GU10 LED Spotlights

GU10 spotlights have been commonly used in spotlighting applications. Traditional GU10 spotlights are halogen lamps. Typically, under current light efficiency of LEDs, 3W LEDs is equivalent to 20W halogen lamps, and 5W or 6W LEDs is equivalent to 40W halogen lamps in terms of lux. Here the picture shows a 4*1W GU10 LED spotlights. See Fg. GU10 LED Spotlights.

From the appearance point of view,  GU10 LED spotlights and halogen spotlights look very similar. However, in fact, the difference between them is tremendous.

GU10 LED Spotlights Dimension

Light Source: light source is the essential difference between LED spotlights and halogen lamps, and that’s the reason why LED lights are much more efficient than halogen lamps. halogen lamps generate light by heating tungsten that covered by halogen gas, while for LEDs, simply describing, when current goes through LEDs, compounded particles in P-N junctions will then release photons (energy). LEDs generate less heat when emitting light, that’s the reason why LEDs are much more efficient than halogen lamps and incandescent bulbs.

Materials: materials are different, LED spotlights usually need aluminum heatsink for  heat dissipation while halogen spotlights do not – their lamp bodies are usually made of plastic.

Driver: furthermore, LED spotlights need drivers (or transformers) in order to be running in existing GU10 fittings, normally 110V or 240V high-voltage fittings.
The picture below illustrates a typical GU10 LED spotlight exploded view. The spotlight is decomposed into 7 components as can be seen from the diagram. The following are the corresponding annotations.

GU10 LED Spotlights Components

1. Lens: beam angle usually customizable
2. Screws
3. LEDs
4. MC PCB
5. Heatsink
6. Plug holder
7. Replacable plug: GU5.3,E26,E27,B22

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.

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.
