The "Asian Games lamp" in Jinhua, Zhejiang can not only illuminate but also prevent mosquito infestation

As one of the six host cities for the 19th Asian Games in Hangzhou, Jinhua City, Zhejiang Province will host football group matches (knockout rounds) and sepak takraw matches during the Asian Games. During this period, 288 "Asian Games lights" will be lit at the Jinhua Sports Center. They can not only provide lighting for the venues, but also prevent mosquito infestations.

Why use "Asian Games lights"? This is determined by the brightness required for the Asian Games television broadcast.

Lux is a unit of illumination. The illumination of general household lamps is 200 to 300 lux, and the illumination suitable for reading is about 500 lux.

According to the relevant person in charge of the lighting service provider of this Asian Games, today's TV broadcasts have entered the 4K and 8K era. If you want to make the expressions on the athletes' faces and the sweat on their bodies clearly visible in the camera, the vertical illumination at the scene needs to reach 2000 lux. .

The "Asian Games lights" have high illumination and can meet the high-definition requirements of television broadcasts.

"During the broadcast, the Asian Games competition venue is a large studio. How to design the lighting in the venue should not only consider the shooting effect, but also consider how to minimize the glare problem in the venue." The person in charge further said that if there is no TV for broadcast, athletes’ favorite illumination is about 500 lux, when the light is soft and not dazzling. However, in a television broadcast scenario, the illumination of the lights in the venue is almost the same as that of sunlight. If the human eye looks directly at the light, it will be uncomfortable or even glare. In this case, technical means are needed to solve the problem.

Relevant R&D personnel installed an extended external anti-glare lampshade on the "Asian Games Light" to convert the light from direct radiation to refraction as much as possible. With the cooperation of all lights in the stadium, nearly 80% of direct radiation was finally eliminated. light.

In southern my country, in summer and autumn, indoor and outdoor lamps are often surrounded by many small bugs. This is because insects are phototaxis and they instinctively fly to bright places. When playing outdoor games, if the lights are blocked by flying insects, the lighting effect will be greatly affected.

For this reason, the "Asian Games Lantern" is also very careful in repelling insects. When the relevant R&D personnel designed the lamps, they removed the light spectrum that bugs like, allowing the bugs to turn a blind eye to the venue lights.

Lamps also generate heat while emitting light. Especially lamps with such high power usually emit a lot of heat. If the heat dissipation performance of the lamp is not good, the components inside will continue to burn and shorten its service life.

In order to solve this problem, the "Asian Games Lamp" developers used a soldering plug-in technology to control the total area of the heat sink of each lamp to about 6 square meters. Even after using it for several hours, the temperature of the lamp is only around 10 degrees Celsius.
