At present, led lighting technology matures, high-power LED light source effect has reached 80lm / W or more, which makes the city street lighting, energy saving is possible. LED lamps, especially high-power led lights, is the impact of rapid pace of traditional street market.

High-power LED street light suggests that it is larger than 30 watts or more, with new LED semiconductor light source lamp. Currently the standard LED lamp is generally the road illumination uniformity (uniformity of road surfaceilluminance) the average intensity 0.48. Spot ratio of 1:2, in line with the road illumination. (Actually 1 / 2 center spot to 25LUX, 1 / 4 center of light intensity to 15LUX, 16 meters from the lowest light intensity 4LUX, overlapping light intensity of about 6LUX. Lens materials currently on the market street improvements optical material, transmittance ≥ 93% , temperature -38-- +90 degrees, anti-UV Yellow UV `no change in the rate of 30,000 hours so it in the new lighting in the city has a very good prospect. on the depth of the dimming, and color and other features not changes due to dimming of solar LED street refers to the use of silicon solar panels supply power LED lights.

Currently high-power LED street lamp standards generally:

1, the conversion rate of 17% light, (the amount of solar energy per square 1000W, the actual efficiency of 170W)

2, lens materials currently on the market street improvements optical material, transmittance ≥ 93%, temperature -38-- +90 degrees.

3, LED lamp lenses, the main lens for LED lights, spot rectangular, the optical material is PMMA material, transmittance ≥ 93%, temperature -38-- +90, `anti-UV rays without yellowing rate of 30,000 hours change,

4, the road illumination uniformity (uniformity of road surfaceilluminance) the average intensity 0.48. 光斑比值1：2 Spot ratio of 1:2

5, in line with the road illumination. (Actually 1 / 2 center spot to 25LUX, 1 / 4 center of light intensity to 15LUX, 16 meters from the lowest light intensity 4LUX, overlapping light intensity of about 6LUX.

6, it is new lighting in the city has a very good prospect. The dimming of the depth and color and other characteristics will not change due to dimming.

7, adapted humidity: ≤ 95%

8, Quality Assurance: 2 years

Despite the rapid pace of development of LED lights, led lights, but the standard is relatively slow. On a global scale, LED lights are not standard is not, like LED lights now have the European standard. In fact, all regions of the LED lights standard, indicators are not the same, we do the LED lights to meet the sales area on the standard requirements, so tender-depth research projects to the LED lights, LED lights local standards, the only way In the fierce market competition will be in an invincible position.

HB LED integrated into the vehicle will encounter problems

HB, LED it has a longer life, usually it can use the 50.000 hours or even longer, but it is also very suitable for long-term status of any environmental lighting, daytime running lights in this area has been well documented, It is because of these characteristics, it is HUD in the car and some new applications are also occupied an important position.

However, the HB LED should now use design technology to integrate it into automotive applications, but also faces many challenges.

One aspect is cost reasons, the component itself, LED lamp price is higher than other lighting options, and this need to reduce the cost of LED solutions for system-level, to improve the reliability of the system.

Another aspect of efficiency, we must increase efficiency to minimize power dissipation, because the car parts generally work in high temperature environment, the ambient temperature around the engine may reach +105 degrees Celsius, which is necessary to reduce the IED drive power consumption, to avoid driver IC or other device driver module overheating.
