LED road lamp shell accessories supply design and development

LED road lamp

LED road lamp whereby the semiconductor lamp, with LED as light source

Because it is a solid cold light source, has no environmental pollution, low power consumption, high light efficiency

, long life and other characteristics, made of LED road lamp.

City lighting lamp is an important part of the traditional street lamps, often by high-pressure sodium lamp, high pressure sodium lamp radiation of **0 degrees,

Light loss big disadvantages caused by the LED light source

The huge waste of energy. At present, the global environment is worsening,

All the countries in the development of clean energy. With the rapid growth of the national economy,

China's energy supply and demand contradiction is outstanding with each passing day, the power supply start there is a serious shortage situation,

Energy conservation is the problem needed to solve. Therefore, the development of new high efficiency, energy saving, long life,

High color rendering index, environmental protection LED on city street lighting energy saving is very important.

Characteristic

LED road lamp with conventional high pressure sodium lamps is different, high-power LED street lamp light source with low

Voltage DC power supply, by GaN based power type high-power LED street lamps lighting

Blue LED with yellow fluorescent powder synthesized high efficiency white light diode, has the advantages of high efficiency, safety, energy saving,

Environmental protection, long life, fast response speed, high color-rendering index unique advantages, can be widely used in City

Road lighting. Housing available PC pipe production, high temperature of **5 degrees, low temperature of - *5 degrees.

Advantage

In 1, LED street lamp itself characteristics *- light one-way, no light diffusion, guarantee the efficiency of light.

In 2, LED street lamp has a unique two optical design, the LED street light irradiation to a desired illumination area

, to further improve the efficiency of light, in order to achieve the purpose of saving energy.

In 3, LED light source efficiency at present has reached ******0lm / W, and still have very large development space,

The theoretical values of **0lm / W. While the high pressure sodium lamp luminous efficiency is increased with the increase of power,

Therefore, the overall efficiency of light LED lamp high pressure sodium lamp ( than strong; the overall light effect is theoretically,

Large power LED lamp advantages

In fact more than **0W high pressure sodium lamp light effect than LED ).

In 4, LED street light color is much higher than high pressure sodium lamp, high pressure sodium lamp color index is only about *3,

While the LED street lamp color index reached more than *5, from the visual psychological perspective, to achieve the same brightness,

LED street light illumination on average than high pressure sodium lamp can be reduced more than *0%,

( with reference to the British standard reasonable lighting ).
