Problems solved by technology

Since the LED module is packaged as a whole, if there is uneven brightness or dead spots at individual light source points, the entire module will be scrapped, causing great waste and increasing production and maintenance costs
Moreover, the encapsulation glue that is packaged into one will generate internal stress, and the molded module colloid will have a certain degree of depression in the middle of the module due to shrinkage, and there will be more serious color block phenomenon after it emits light, that is, the light-emitting direction changes with a certain degree. The deformation angle changes, creating inconsistencies across the entire color surface
In addition, the ink color consistency of the LED module shell is extremely difficult to control, which often affects the appearance of the LED display device
In addition, the encapsulation colloid formed by the encapsulation method used in this encapsulation structure is prone to defects such as incomplete shape, dents, and air bubbles, which directly lead to a high rate of defective products in the encapsulation structure

Abstract

The invention relates to one LED sealing structure, which comprises circuit board, several LED light units on circuit front, wherein, the circuit board back is set with terminal to outer circuit. The invention also provides one LED sealing method, which comprises the following steps: processing special mode board; binding LED light chip; mode loading with down mode board facing down with each LED light unit contained into each module particle; glue injecting and fixing step.

Description

technical field [0001] The invention relates to an LED package structure and a package method. Background technique [0002] Due to the characteristics of LED light source, such as low power consumption, long life, sensitive response, and no toxic substances, this new type of energy-saving and environmentally friendly light source has been widely used, such as in backlight, display screen, car lights and various landscape lighting. place etc. [0003] At present, the packaging methods of LED mainly include: in-line LED lamp with bracket, SMD LED lamp and integrated LED module. [0004] The in-line LED light is composed of light-emitting chips, copper or iron brackets, and epoxy resin. It is characterized by various forms, easy replacement, and a wide range of light-emitting angles. It can be used as a point light source, and can be used as a surface light source when multiple modules form a module. , line light source. Bracket-type LED lamps need to be inserted and welded...
