The opening ceremony of the 2008 Beijing Olympic Games "Dream Earth"
Summary of results (main use, technical principles, key technologies and innovations, applications and benefits, problems):
First, the main purpose:
The development of this project has two purposes: one is to replace the high-power LED on the traditional stage with the color changer era. The traditional heaven and earth row is not only noisy due to the use of the color changer, but also has a slow color change and uneven color. Due to the different design principles of LEDs, the noise-free color change response speed is fast, subverting the monopoly pattern of traditional lamps in the stage and studio, and the majority of lighting engineers have more and better choices in using lighting. In addition, although the initial purchase cost of the LED floodlight is higher than that of the general light fixture, it can be seen in the operation that the statistical data we have saved in the high-power LED in one year has already recovered the initial cost, and the LED has a long service life. In the same working hours, the traditional light source needs to be replaced more than 3 times, and this is not a small fee. LED is a cold light source, no matter how long the irradiation time, there will be no obvious temperature rise, the savings for air conditioning can not be underestimated, the above analysis is enough to see that the economic benefits brought by LED in energy saving and consumption reduction is immeasurable. In the global environment of energy shortage, the birth of high-power LED is a benefit for all mankind.
The second is applied to outdoor architectural lighting, this high-power LED product protection grade IP65, waterproof sunscreen, strong anti-interference, micro-computer control. Due to the particularity of outdoor lighting, the anti-aging requirements for waterproofing and sunscreen above the lamps are high.
