LED Blue beacon light technology and its characteristics

LED Blue beacon light , called as the name implies, refers to the lamp products using LED (Light-emitting Diode, light emitting diode) technology as the main
White LED lighting
The white light LED lighting (16)
To be luminous source. led warning lamp  is a solid semiconductor components, the use of current clockwise circulation to the semiconductor p-n junction coupling, again by the semiconductor separation of negatively charged electrons and positively charged hole two carrier combined with each other, and produced photon emission, different types of LED can be emitted from the infrared to blue, and between violet to UV between different wavelengths of light. The new development in recent years is in the blue light LED is coated with fluorescent powder, the blue LED into a white LED products. This operation generally need to match driver circuit (LED Driver) or power supply (Power Supply), the main function of drive circuit or power supply is the AC voltage into a DC power supply, and at the same time to complete compliance with led blue beacon light  voltage and current, component to drive the matching.
The bulb volume LED Blue beacon light small, light weight, and with epoxy resin package, can withstand high strength mechanical shock and vibration, not easy to be broken, and the brightness attenuation cycle is long, so the service life can be as long as 50000-100000 hours, more than 1000 hours and fluorescent light tube of conventional tungsten light bulbs of 10000 hours. The LED lamp life of up to 5 ~10 years, so not only can reduce lamp replacement costs, but also because of its minimal current can be driven light-emitting characteristics, in the same illumination circumstances, power consumption is only 1/2 of the advantages of a fluorescent lamp, so led rotating beacon light  also has energy saving and energy saving. But as part of LED technology is not enough, so initially used in the luminaire shortcomings include the light quality (color, consistency, temperature), heat is not easy, the poor and the price is high, and the improper cooling, will cause the brightness and the circuit of LED lamp component service life accelerated decay. Manufacturing technology make a spurt of progress, the above shortcomings, including the thermal resistance of LED decreased gradually, the light quality also in ascension. In 2008, in addition to the luminous efficiency LED Bai Lengguang had reached 100 Lm/W, while the LED warm white luminous efficiency, is expected in 2010, also from 70 Lm/W up to 100 Lm/W. Compared with other common light source, tungsten lamp, fluorescent lamp is about 15 Lm/W about 45~60 Lm/W, HID lamp is about 120~150 Lm/W, the luminous efficiency of LED apparently has gradually with the advantage; the following is the comparison of LED and other common lamp lamp:
