LED light source is a light source with light-emitting diode (LED) as the luminous body, which has the characteristics of high efficiency and long life. LED light sources mainly include ring light sources, bar light sources, linear light sources, back light sources, backlight sources, external coaxial reflective light sources, internal coaxial point light sources, and hemispherical ridged light sources.
With the continuous in-depth research on semiconductor light-emitting materials, the continuous progress of LED manufacturing technology and the development and application of new materials (nitride crystals and phosphors), ultra-high-brightness LEDs of various colors have made breakthroughs. The efficiency has improved a lot. In terms of chromaticity, all colors in the visible light band have been realized. The most important thing is the emergence of ultra-high-brightness white LEDs, which makes it possible for the LED application field to leap over to the high-efficiency lighting source market. Someone once pointed out that high-brightness LED will be one of the great inventions of mankind after Edison invented the incandescent light bulb.
1. High luminous efficiency. After decades of technological improvement, the luminous efficiency of LED has been greatly improved. Moreover, its light has good monochromaticity and narrow spectrum, and can directly emit colored visible light without filtering.
2, less power consumption
3. Long service life, using electronic light field radiation light, filament light is easy to burn, thermal deposition, light attenuation and other shortcomings. The LED lamp is small in size, light in weight, and epoxy resin encapsulated, which can withstand high-strength mechanical shock and vibration, and is not easy to break.
4. Strong safety and reliability, low heat generation, no heat radiation, cold light source, safe to touch: it can accurately control the light type and angle of light, the light color is soft, no glare; it does not contain mercury, sodium, etc. which may be harmful to health Of the substance. The built-in micro-processing system can control the luminous intensity, adjust the luminous mode, and realize the combination of light and art.
5. It is conducive to environmental protection. The LED is a solid luminous body, which is shock-resistant, impact-resistant and not easily broken. The light source is small in size and can be combined at will. It is easy to develop into a light, thin, short and small lighting product, and it is also easy to install and maintain.
The above is the COB integrated light source characteristics, the LED light source characteristics are analyzed in detail, I believe you can also understand the difference between these two kinds of lights, the following recommends the LED light source and cob integrated light source of Liyang Optoelectronics, and the quality is guaranteed.
