Development of high-power LED ceramic packaging technology The current state of the light-emitting diode has been widely used in portable products and buildings today, such as mobile phone backlights, flashlights, car warning lights and brake lights, building decorative lights, Landscaping lights and underground lights.
With the advancement of technology, at 350mA operating current, the luminous flux of LED can exceed 100 lumens and reach the threshold of illumination source. Not only that, but LEDs have the following unique advantages, which are enough to make LEDs gradually replace existing light sources;
1. Technical aspects: LED has the advantages of high reliability, high light source quality, stability and long life, and the luminous efficiency (lm/W) can still be greatly improved continuously, and will one day be higher than the existing light source;
2. Economic benefits: LED has the advantages of energy saving, reduced maintenance costs and sustainable improvement of lm/dollar;
3. Green: The LED meets the requirements of RoHS and CaliforniaTitle24. Unlike incandescent bulbs, it will be completely banned due to the inability to pass RoHS. Based on the above, it is believed that in the near future, LEDs will have the opportunity to be applied to street lights, street lights, parking lot lighting, xenon lights and landscaping lights, etc. In the future, there will be more opportunities to apply to general lighting such as fluorescent lamps and residential lighting, and photos of related applications such as Figure 1 shows.
