| Since 2009, "10 City 10 000" started, we | | | | cavitation. As much air interface thermal |
| triggered the frenzy of the LED lighting, LED | | | | resistance, not conducive to thermal diffusion, it |
| street light technology became a hot topic, but | | | | has greatly increased the overall interface thermal |
| this did not solve the LED lamp technology. LED | | | | resistance. " |
| by senior engineers and Tianjin Dongli District | | | | Landscape Management Committee of Tianjin city |
| Government jointly organized the "theme of the | | | | and director of Da Qing Chen is not |
| Fifth China LED Industry Summit Forum" meeting, | | | | recommended for more than 3W high power LED |
| many industry experts pointed out that LED | | | | light source as road lighting. Because of high |
| street light technology faces many challenges, | | | | power LED must be accompanied by the |
| Ningbo Liaoyuan technology with the total labor | | | | formation of high current, high current leading to a |
| Hai Jun Chen to his LED lamp technology solutions. | | | | large heat, an increase of lumen. He told the |
| In this forum, senior street design expert, said | | | | audience that "there are several companies |
| the Guangdong city of Chiu Shun Xu Even in this | | | | producing domestic high power integrated module |
| year's Guangzhou Lighting Fair, on some | | | | of the luminous efficiency has been achieved |
| companies in product R & D efforts, | | | | 130Lm W or more, the highest close to 150Lm |
| production of products gratifying. For street | | | | W, and temperature control in a 50 ?. In the |
| design, Xu city prompted the industry to consider | | | | second half, to 160Lm W These are indisputable. " |
| the wind resistance problem, "Let your lights can | | | | Huazhong University of Science Professor Luo |
| really stand in the rain." Now many lights did not | | | | Xiaobing said, LED device cooling problem is a |
| take into account the thermal design of air | | | | systemic problem. A LED chip thermal resistance, |
| convection, the heat caused no real export, | | | | thermal resistance interface materials, diffusion |
| reduce LED life. | | | | resistance, environmental resistance and so on, |
| At the same time promoting the city ? modular | | | | "We should also reduce the thermal resistance of |
| design. He believes that modular power supply not | | | | all is the key to solving heat." He believes that |
| only to avoid the risk of high power, IP protection | | | | through the development of multi layer ceramic |
| is also easy to maintain them as easy as the | | | | technology and to achieve integrated LED |
| conventional lamp, thus greatly reducing the | | | | package and multi purpose, LED packaging |

| Hai Jun Chen, Ningbo Liaoyuan technology that | | | | are CoB major trends in technology. |
| help increase white light LED street lamp road | | | | Personally, I think, LED lights replace the high |
| lighting safety. He believes that lighting is not only | | | | pressure sodium lamp, energy saving and emission |
| to consider the central vision, but also consider | | | | reduction is a trend in the future, just a technical |
| the ability of peripheral target detection, including | | | | development and progress also need time for |
