Analysis of the development direction of LED lighting
With the continuous development of smart cities, the application of LED lighting is also increasing. As a new product, LED lighting is driving the development of various technologies related to it. At the same time, in order to better meet market demand, it is developing In the process, a variety of products with different functions are gradually produced. Due to the low energy consumption, LED lighting is regarded as an ideal alternative to traditional lamps that consume a lot of energy. Coupled with rich colors, LED lighting is widely used in home lighting, commercial lighting, landscape lighting.
1. Dimming is also the development direction of LED lighting. The dimming method of domestic indoor products is mainly 0~10V, and the DALI dimming method that is relatively mature in the international application is still relatively small. Because we realize that LED dimming may cause the problem of color drift, the dimming requirements are no longer simple voltage regulation and current regulation, but mainly PWM. However, this will also bring EMC and other issues that need to be further resolved.
2. LED light sources and LED lighting lamps use LED light sources of the same specification, which can not only use the original transformer and lamp body, but also replace the light source like traditional lamps. In addition, COB packaging and the trend of light engines complying with ZHAGA specifications can also be used to standardize LED light sources, increase luminous flux while maintaining the same size, and reduce design and manufacturing costs. For spotlights, the ultra-narrow beam angle is one of the advantages of the design and manufacture of lighting manufacturers.
3. In the choice of color temperature, the domestic preference is for the warm and comfortable feeling brought by the color temperature of 2700K and lower. In addition, special attention should be paid to photobiological safety for indoor products, and different filters should be designed to achieve different light distribution effects.
