1, see the use of lamps and lanterns: cooling speed determines the degree of light of the whole lamp and the life of the radiator is too small will make high temperature accumulation in the light inside. Lamp beads for a long time in high temperature work, light failure soon, life is very short.
2, see the lamp drive power (commonly known as the transformer): transformer quality also determines the life of the whole lamp. Transformer internal use of electronic components, design determines the efficiency of the transformer, power factor, stability, temperature rise, the service life. The company used by the drive are broadband voltage drive (constant current constant voltage), the output current voltage stability.
3, to understand the lamp beads of the brand and package: light beads quality determines the lighting effect of the whole lamp, packaging technology affect the quality of lamp beads, life, heat and other key factors. Lamp beads chip with the US chip, Taiwan chips, domestic chips and so on. Different brands, the price difference is large, the lighting effect is also big difference.
LED ceiling light relative to the advantages of traditional technology:
1, LED ceiling light size, anti-vibration impact, more traditional lighting applications, LED lanterns longer life, and the characteristics are more attractive.
2, high-brightness light-emitting diode is a high-power, high brightness LED, with its production of LED ceiling lamp products longer life, smaller size, and flexible design, has become a substitute for traditional incandescent bulbs, energy- The choice of light.
3, LED ceiling light monochromatic good, and different from the traditional cold cathode fluorescent tube (CCFL), LED does not contain the spectrum of ultraviolet and infrared radiation, does not contain harmful metal mercury metal elements, safe and healthy, environmentally friendly.
4, LED driven by the DC voltage, even in low voltage and low current conditions can also maintain high brightness. In the same lighting applications, compared to other lighting programs, LED ceiling light can save more than 80%. High brightness LED life may be up to 60000-100000 hours; and incandescent bulbs, conventional three primary colors energy saving lamp life of only 1000-8000 hour. In addition, the LED response speed is very fast (100ns -1ns). In view of this, LED ceiling light compared to ordinary lighting, the advantages can be seen, so with the incandescent lamp was eliminated, conventional three-color energy-saving lamps gradually replaced, engineering lighting, commercial lighting market will eventually be LED lighting occupy. In the low-carbon economy, energy saving and environmental protection in the context of China's LED lanterns and other related industries in recent years, rapid development. With the increasing demand for energy saving and environmental protection, LED industry development prospects are promising, many companies have to develop industrial development policies to promote the rapid growth of LED industry.
