The luminous efficiency of LED lamps is higher than that of incandescent lamps and fluorescent lamps. In theory, the lifespan is very long, and the light can reach 100,000 hours. The actual product is basically 30,000-50,000 hours, which is enough for household use; no ultraviolet and infrared rays Radiation; does not contain lead, mercury and other polluting elements.
A major downside of LED lamps is that their quality varies widely on the market. While the reduction in price has been a positive development in recent years, the inferior quality of low-priced options is a genuine cause for concern.
When selecting an LED lamp, it is essential to define the criteria for blue light danger first. The IEC/TR 62778 standard should be used to evaluate lamps with integrated or LED modules for potential blue light hazards.
For portable lamps and night lights for children, the blue light hazard level measured at a distance of 200mm shall not exceed RG1.
In the case of portable lamps and portable luminaires, if the RG1 level of the blue light hazard measured at a distance of 200mm is exceeded, it is necessary to place a warning sign outside the lamp that is prominently visible, which reads "Avoid direct eye contact with the light source".
Enterprises must consider several factors when marking the blue light hazard symbol on their products. Firstly, the symbol must be easily visible to users, but it should not be located in a way that allows the light source to be seen when viewing the symbol. Therefore, it is not advisable for enterprises to affix this symbol on the LED desk lamp's installation surface or light-emitting surface.
For fixed luminaires, manufacturers must conduct experiments to determine the critical distance when the blue light hazard level measured at a distance of 200mm exceeds RG1. The distance value should be included in the product manual to provide guidance for lighting designers and construction parties. By following these guidelines, enterprises can ensure that their products adhere to safety regulations and prevent potential harm to users' eyesight.
Although the future of LED seems promising, the journey ahead is still challenging and full of obstacles.
