Title of invention: LED constant current high -voltage lamp area with control by temperature change function

Abstract: The utility model discloses a LED constant current high -voltage lamp area with control by temperature change function, including LED lamp area and control by temperature change constant current IC, a serial communication port, a LED lamp area internally mounted PCB board, PCB board upper end is provided with more than one unit lamp plate, all installs a plurality of LED lamps on the every unit lamp plate, two at least main heart yearns of LED lamp area internally mounted, every unit lamp plate have two parallelly connected line weld dishes at least on the PCB board, main heart yearn is through the on line is electrically conductive with parallelly connected line weld dish, parallelly connected seam welding is on parallelly connected line weld dish, connect V's positive pole of the one end in LED lamp area, an installation control by temperature change constant current IC on the PCB board in LED lamp area, another termination of control by temperature change constant current IC at power V's negative pole or cluster between every unit LED lamp cluster. The utility model discloses the high -voltage lamp band -pass is crossed and is used the constant current IC who has the control by temperature change function, and control is through LED's electric current to reach and reduce that the lamp pearl life -span that arouses because of generating heat shortens or lead to the lamp outband hide glue material accelerated mesh that ages because of the high temperature.
