The emission principle of white light-emitting diodes is slightly different from that of other light-emitting diodes. At present, there are two lighting modes on the market that can make light-emitting diodes emit white light. Please see the editor's explanation below. The first type is a white light-emitting diode that uses a two wavelength blue light+yellow light emission mode.

2835 patch led lamp bead white light is the most used in the light source, especially: lamp light source, point light source, lamp strip, lamp group and other products have been applied. At present, the 2835 white light on the market has been divided into some models for different brightness, such as regular bright...

LED patch LED has no zero light failure, light failure is bound to occur, zero light failure does not exist, but the size of the problem. At present, the commonly used brands of chip LED are divided into three camps, the United States and Japan chip quality is more expensive, followed by Taiwan, and China's LED chip quality is relatively low in price. The key to different quality LED chips is life, and life is determined by light decay. Small light decay, long life, long life, high price.

n the first quarter, UV industry chain enterprises strengthened their research and development of UVC LED technology. 256nm Japan created a UVC LED with a luminous efficiency of 50mW through its exclusive AIN UV LED technology, and continued to strengthen its technology to develop 200MW products. The 275nm deep ultraviolet LED has achieved a luminous efficiency of 20mW at 100mA and has achieved stable mass production and shipment...

Infrared emission tubes typically use semiconductor materials such as gallium arsenide (GaAs), gallium arsenide aluminum (GaAlAs), etc., packaged in fully transparent or light blue, black resin. Currently, infrared emission tubes are mainly used as signal sources for various photodetectors, specifically in remote control, alarm, and wireless communication.

The difference between direct insertion LED beads and LED patch LED beads.Let's first take a look at the characteristics of LED beads? The angle of LED beads is made very small, which is due to the concentrated light and long range, but the illumination range is limited; The general angle of LED mounting is very large, which belongs to the scattered light and wide illumination range, but the range is relatively close.
