| increasing scarcity of resources, the greenhouse | | | | the source. The light source cavity protection grade |

| significant hazards, air pollution on the Earth's | | | | as conventional lamps lighting conditions to ensure this |
| environment more and more serious, saving energy | | | | protection, you can make any shape, Since the LED |
| and reducing consumption requirements of the | | | | street lamp and the semiconductor launched the |
| international community is increasing, today's energy | | | | market, long-life light source, with easy superiority of |
| conservation become the most important task. As | | | | a reasonable distribution of light, temperature |
| early as 1996, China officially launched on the green | | | | variability, high color-rendering index of the edge, |
| lighting project, the lighting project to save resources, | | | | low-voltage, current power supply of the light source |
| prevent pollution, and our future generations. Over | | | | with a highly efficient energy-saving trends. Used for |
| the years, through the joint efforts of all various | | | | LED street lamps have natural advantages, its |
| departments, as a fourth-generation semiconductor | | | | advantage lies in: 1) LED as a point light source, if the |
| light source (LED) lighting products has been rapid | | | | design is reasonable, to a large extent directly |
| development in the energy saving achievements. | | | | address the traditional spherical light-emitting light |
| Chinese road lighting outdoor lighting accounts for a | | | | source has to rely on to solve the second take-ray |
| whole 30% of electricity consumption, and it is | | | | and optical loss issues; 2.) Light irradiation uniformity |
| closely related to production and life. LED street | | | | surface controlled, in theory, can be done entirely in |
| lighting as an important outdoor applications, its | | | | the target area evenly, which light source to avoid |
| advantages: | | | | the traditional "bright light" phenomenon of light |
| 1. high-power long-life LED street lamp | | | | waste; 3) Color temperature optional, so the |
| Members of the focus of great concern, as many | | | | application of different occasions, but also improve |
| domestic and foreign experts and the company's | | | | efficiency, reduce costs an important way; 4) |
| products described in publicity pictures 5-10 million | | | | Technology is still considerable room for |
| hours, and optimistic attitude, a matter of fact, | | | | improvement. |
| high-power LED street lamp life depends on the | | | | 4. LED streetlights with the rationality of the optical |
| following points: 1) LED light source chip quality, | | | | light |
| value-ray attenuation. 2) LED packaging technology, | | | | LED lights with different traditions, it has a point light |
| Consistency and reliability. 3) LED light source is a cold | | | | source, high brightness, narrow-beam output and so |
| light, but the LED semiconductor itself will have heat. | | | | on. LED street lamps so the first thing to consider |
| LED heat dissipation, LED to ensure good working | | | | the limited use of the full flux of radiation to the |
| conditions. (4) power supply, current-driven assure | | | | effective range, street lamps lighting the road asking |
