Shenzhen mei'erte photoelectric Limited company is the LED lamp manufacturer located in Shenzhen, the main production and sales of LED products are as follows: LED flood light, LED lamp, LED lamp, LED lamp, LED ceiling lamp, LED lamp, LED lamp, LED lamp, LED bulb, lamp, LED mining lamp, LED track light, LED lamp fittings etc..
For general LED lighting, people need to be close to the sun light quality, so the white LED is a major index of semiconductor lighting technology. LED has the advantages of small size light weight, low driving voltage, full color, long service life, high efficiency, easy to control the light, but the white LED general lighting requirements there is still a certain distance, there are many technical and cost problems solved urgently.
The main technology of semiconductor lighting system of the:
1) LED lamp system heat Consultant
Usually, LED is called a cold light source, this is because the LED light-emitting principle is the electrons pass through the composite directly emit a photon, without the need for thermal process. But because of the existence of Joule heat, LED also has a heat with the same light, but also for high power and multiple LED applications, heat Many a little make a mickle. and cannot be underestimated, LED differences in incandescent lamp, fluorescent lamp and other traditional lighting source, high temperature will shorten the life, even the termination of its consumption. And the LED is a temperature sensitive device, when the temperature increases, the efficiency sharply, so the system structure design and heat dissipation technology and LED application must squarely face the issue. Because of the forced air cooling is usually in the light source is not desirable, so as the input power increases, heat sink and other increases in natural convection cooling way on LED lamps and light source design play an increasingly important role.
2) improve the color
The current white LED general consumption yellow light hair blue LED superimposed by a blue light excitation of yttrium aluminum garnet (YAG) phosphors for white, synthesis. Because the luminescence spectra contain only blue, yellow two spectrum, so there exists higher color temperature, color index of the low, do not accord with the general lighting requirements. Sensitivity of human eye color is much higher than the sensitivity to light intensity, the illumination, color light source luminous efficiency greater than. The fluorescent powder so adding glowing and can keep high luminous efficiency is the great subject of the white LED lighting.
3) two times optical design of LED lighting system
The traditional incandescent lamp, fluorescent lamp for a long light source as a reference to determine the lamps optical and shape of the standard, so the LED lighting system should consider to abandon the traditional lamp assembly and LED light-emitting module, take full account of its optical properties, lighting design differences for LED light special. Optical system design content mainly includes the following parts:
Based on the object, the luminous flux of the lighting needs, decide the number and power of the shape, the size of the LED optical system;
The several LED light-emitting tubes combination design into a point light source, the ring light source or a surface light source "two light", on the basis of the two light source combination, calculate the illumination optical system;
The illumination optical system design of a "two source" on each LED tube light dispersion limit is very important.
MeiErTe photoelectric Limited company is located at Shenzhen Baoan Guangdong, committed to the development and production of LED energy-saving lamps, LED lighting species produced are: LED flood light, LED lamp, LED lamp, LED lamp, LED ceiling lamp, LED lamp, LED lamp, LED lamp, LED ball, bulb lamp, LED lamp, LED track light, LED lamp fittings etc.,
