HV technology used in solar led street lamp

 

The HV the solar led street lamp is made ​​directly on silicon chip production system on a chip (SOPs), which is a revolutionary advancement of the LED chip manufacturing technology. A 2-inch silicon wafers, one can produce tens of thousands of LED die, but using common technologies and processes to produce discrete LED parameters. So, after the production, manufacturers need to individually measure the parameter file, the client can only take the third gear of the adjacent units (light) in order to ensure consistency of display light color. The HV LEDs in the production of a new generation of technology and superb processing technology, tens of thousands of LED die in the same silicon wafers on the parameters exactly the same so easily in chip production, the nearest composition of the SOC HV LEDs for such as the 16 LEDs on the HV45, all of their electrical parameters are exactly the same. HV LEDs for easy to use, cost control. Otherwise a COB HV LED is the adoption of the aforementioned general-purpose technology to produce the parameters of discrete led high bay chips die, will be the same configuration of the test data together, re-combined into a light body. Due to the need to individually test, matching, filtering, and combinations, there are many parameters can not be dispersed paired combination use, production costs will be high.

 

In addition to the low-voltage solar led street lamp driver chip, the domestic high-voltage LED driver chip has also emerged market, the high-voltage LED chipset high-voltage, low current, compared with the common low-voltage LED low voltage, high current working environment, when the fever HVLEDs work reduce the; HVLEDs only need a high-voltage constant-current source can be a good, high-voltage constant-current power transformer, electrolytic capacitor low-voltage LED driver power supply and electrolytic capacitor life.
