Abstract

The invention discloses a double-color-temperature COB hybrid chip device and a packaging method of a COB system. The system comprises a COB system and a control circuit mechanism. The COB system comprises a control circuit board, a chip mechanism arranged on the control circuit board, and a fluorescent glue mechanism covered on the chip mechanism. The fluorescent glue mechanism comprises at leasttwo fluorescent glue units which can be mixed to generate the light, wherein the fluorescent glue units correspond to different light source light colors. The chip mechanism comprises a plurality ofchip units. The control circuit mechanism is electrically connected with the chip units, and the control circuit mechanism is used for outputting working voltage corresponding to input voltage of thecontrol circuit mechanism to the chip units. According to the method provided in the invention, the combination of mixed chips is adopted, and the voltage value of each chip unit is adjusted. Therefore, the stepless adjustment of the double color temperature can be realized, and the function is optimized.

Description

technical field [0001] The invention relates to the technical field of COB chips, in particular to a dual-color temperature COB hybrid chip device and a packaging method for a COB system. Background technique [0002] The descriptions in this section merely provide background information related to the present disclosure and do not constitute prior art. [0003] COB (Chips on Board) package is a package in which the LED chip is directly welded on the PCB board. According to data, the annual global COB business license market capacity is close to RMB 4 billion, a year-on-year increase of 6.5%. With the continuous expansion of the lighting application market, the requirements for light quality are getting higher and higher, which promotes the continuous innovation of packaging and chip technology applications, and the COB application technology is also gradually improving. To AL board + flip chip (filp chip) + integrated circuit + packaging, reduce the wire bonding process, ...
