At the present time, it’s very desirable that more and more led high bay and LED Tunnel Light are used in outdoor and industrial lighting. As the development of LED technology and reduction of price, while the rising of fluorescent powder’s price, it provides a good opportunity for LED entering the indoor field.
However, once LED enters into indoor lighting, the safety problem can’t be ignored. If it is made into spotlight, table light, flashlight or laser pointer, children would be very interested in them. If so, safety becomes much more important to us. For example, if laser pointer directly shines children’s eyes, the retina would immediately be injured. The radiation of LED lighting is objective existence so that it is the most protective part to manufactories.
Even though the mainstream product in the market is still traditional lighting fixture, it’s no doubt that LED would take the place of them sooner or later. Once LED occupies the market, the country should compulsory execution the standard of IEC/EN 62471. Besides, the relatively testing laboratory must have had the matched ability, otherwise, the damage of light and biological safety may rise. Therefore, it’s very important to correctly test the evaluation indicator of LED optical radiation strength. Even if LED module reaches the standard, fixture may not be able to do. What’s more, fixture also should be considered light distribution because it’s not easy to distinguish the light strength by eyes. All these problems must have solved by correct testing method and examined by senior laboratory to promise a good lighting effect and minimize the damage.
LED lighting must be designed according to application. Some places pursue longevity and high efficiency while others need much higher comfort and safety. Therefore, when developing product, manufactories should have different choice in accordance with the environment and carefully consider the factors of luminous, lifetime, the comfort of light, etc.
