Title:
LED LIGHT SOURCE USED BASED ON ULTRATHIN LIGHT BOX HAVING A THICKNESS OF 5-10CM
Document Type and Number:
WIPO Patent Application WO/2017/185400
Kind Code:
A1
Abstract:
An LED light source used based on an ultrathin light box having a thickness of 5-10cm, comprising a PCB board (2) made of an aluminum substrate, an LED lamp group mounted on the bottom face of the PCB board (2), a constant current chip mounted on the PCB board (2) and electrically connected to the LED lamp group, and a diode connected between the constant current chip and the LED lamp group. The LED lamp group consists of seven LED lamps (1) connected in series, each LED lamp (1) being provided with a secondary light distribution lens (3). A power supply connector (4) connected to the LED lamps (1) is mounted at both ends of the PCB board (2). This invention applies, by means of the improvement of the optical lens, an LED lamp onto an ultrathin light box, achieves a large illumination area of the LED lamp, and enables convenient mounting with a low cost.
