High output white led’s big trouble: over heating

 

LED industry in the past in order to get the full white LED beam, once the development of large-size LED chips trying to take this way to achieve the desired goals. But, in fact, exert power white LED lasts for more than 1W beam but will drop 20 ~ 30% reduction in the relative luminous efficiency. In other words, if the brightness of the High output white led is several times larger than traditional LED power consumption characteristics beyond the fluorescent , you need to overcome the following four topics: inhibit the temperature rise to ensure that the service life, improve the luminous efficiency, and luminescence Properties of equalization.

Temperature rise solution to the problem is to reduce the package thermal impedance; to maintain the service life of led high bay is to improve the chip shape, a small chip; improve the LED luminous efficiency of the method is to improve the chip architecture, small chip; The luminescence properties homogenizationthe method is to improve the LED packaging methods, these methods have been developed one after another.

For light-emitting characteristics of uniformity, is generally believed to improve High output white led uniform concentration of fluorescent material and the phosphor production technology should be able to overcome this trouble. As described above to improve the applied power at the same time, it is necessary to try to reduce the thermal resistance, improved heat dissipation problem. The specific contents are: to reduce the chip to the package thermal impedance, inhibiting the thermal resistance of the package to the printed circuit board, chip cooling smooth.

Why is "household led lights” hard to be accepted by ordinary people?

 

It is no doubt that household led lights can in the dominant position in the future lighting market, since it is energy-saving, harmless, environment friendly. A salesperson from Shijiazhuang Metro Lighting Market indicated that household led lights can save a large amount of energy compare with filament lamp and energy-saving lamp (with similar brightness). After continuous lighting for 6000 hours, LED lights can save 60% electricity than energy-saving lamps, and as high as 90% that of energy than filament lamp. The life span of household led lights is 5 times as much as energy-saving lamps, and 20 times as much as filament lamps.

Although the advantages of LED lights in energy saving and environmental protection are significant, however, the market demand is as heavy as experts expected.

Vendors from Shijiazhuang Metro Lighting Market said to reporters that in the field of household lighting, fluorescent lamps occupied about 80%, while the proportion of new LED light is only about 2% ~ 3%. His daily sales volume for household led lights is only 3-5, even less than that of led high bay.

Similar to energy-saving lamps, the promotion of LED lights among ordinary family is now in deep water. “The price is too high to be accepted by ordinary people”. It is the biggest factor that has the LED lights now mainly used for commercial purpose.

“In addition, household led lights have not been familiar by customers. The existence of LED lights in the lighting market is much shorter than that of energy-saving lights.” One of the vendors said. He believes that the drab style-design is another reason for the unpopularity of the household led lights. They cannot meet customers’ demands.
