The semiconductor lighting industry is facing a rare historical opportunity. The output of LED packaging and application products in China has accounted for 70% of the world's total. The development of the LED industry is taking advantage of the development of the LED industry. It is actively developing in the direction of advantages, promoting technological progress and maturity of production processes, thus promoting China's semiconductor industry. The overall advancement of lighting technology has also played a crucial role in the arrival of the era of semiconductor lighting.
On August 30th, the 8th High-tech LED Industry Summit held in conjunction with the High-tech LED Boutique Exhibition was held in the Century Hall of the Shanghai International Convention Center. The technical section of the forum revolves around "LED Lighting Technology - Problems and Solutions", LED lighting design and application engineering - the theme of deciding the segmentation field, etc. The sapphire production process in the whole industry chain of LED, middle and lower reaches, LED epitaxial chip technology at home and abroad, phosphor, detection equipment, LED devices and modules, and OLED From the point of view to the topic, I shared a comprehensive key technology with the guests. Participants expressed that it was a very rare training and promotion opportunity.
Wang Xiaoming of the Shanghai Lighting Society brought a comparison of the LED streetlights in 2010 and 2011. In 2011, the 1500h lumen maintenance rate of LED lamps was more than 99%, accounting for 54%; in 2010, the LED lamps 1500h lumen maintenance rate was greater than 95%, accounting for 7 %. In 2011, the color temperature of LED lamps was less than 5000K, accounting for 27%; in 2010, the color temperature of LED lamps was less than 5000K, accounting for 17%.
At the same time, Wang Xiaoming suggested that the development of LED street lamps should face the actual standards, life expectancy ≥ 25000h; the weight of the lamps is controlled within 10-15KG. The color temperature should be ≤5000K; the color rendering index should be determined according to the standard of use. LED module drive power can be replaced in the field and other requirements.
