Abstract

The invention discloses liquid-packaged high-power three-primary-color LED chip array distribution and production. According to the invention, a chip array is arranged on a substrate, odd-numbered lines of three-primary-color LED chips are arranged according to a sequence of RBG, even-numbered lines of three-primary-color LED chip are arranged according to a sequence of BGR, the ratio of numbers of the three types of chips both in an overall scope and a local scope can be kept to be 1:1:1, and the chips of the same color in the three-primary-color LED chip array are connected in series and / or in parallel according to an electrode array mode; and then the substrate is placed in a metal shell, a transparent baffle plate is arranged at an opening of the shell, then the part above the chips is filled with a light transmission insulating liquid, and the light transmission insulating liquid is sealed in a metal cavity through the transparent baffle plate. The transparent liquid takes heat away quickly through convection and transfers the heat to the metal shell, and the heat quickly spreads to the air, so that the heat dissipation efficiency is higher. A white-light LED realized adopting the liquid-packaged high-power three-primary-color LED chip array distribution and production is good in light emitting uniformity and high in display index.

Description

technical field [0001] The invention relates to the field of lighting sources, in particular to a liquid-encapsulated high-power LED device and an array distribution of R, G, and B three-primary color chips. Background technique [0002] Solid-state lighting based on Light Emitting Diode (Light Emitting Diode) is considered to be the light source of the 21st century. Compared with traditional light sources, Light Emitting Diode has the characteristics of high luminous efficiency, long life, small size, and fast response. [0003] In the early application of light-emitting diodes, due to the relatively low power, little heat is generated, and the heat dissipation problem does not need to be considered. With the emergence of high-brightness monochrome and white light-emitting diodes, it has become a trend to apply light-emitting diodes to daily lighting. When using power-type light-emitting diodes for lighting, one of the most important problems that needs to be solved is heat...
