High-reliability module system

Abstract

The invention provides a high-reliability module system. The high-reliability module system comprises at least one gland, at least one base, an LED light-emitting module and a COB light source. A plurality of first vector bonding pads are arranged in the gland; a solder paste layer is arranged on the first vector bonding pad in a covering manner, and the first vector bonding pad is electrically connected and fixed with the base through reflow soldering; the base is provided with a connecting device which is electrically connected with an external driving device; the base is provided with a plurality of second vector bonding pads; a solder paste layer is arranged on the second vector bonding pad in a covering manner, and the second vector bonding pad is electrically connected and fixed with the gland through reflow soldering; the coaxiality precision between the base and the gland and between the LED integrated light-emitting module or the COB light source can be effectively controlled, poor assembly and optical abnormity caused by dislocation are avoided, and the reliability of the LED module is improved.

Description

technical field [0001] The invention relates to the field of LED lighting modules, in particular to a high-reliability module system. Background technique [0002] As we all know, in order to further reduce the labor cost of assembly and manufacturing and raw material cost, most lighting assembly factories simplify the process technology and raw material performance of the indispensable materials of LED modules. Therefore, while considering the cost factor, The most important quality issues such as product reliability are ignored, resulting in a large number of product failures during the use of end users, resulting in very large economic losses. [0003] During the assembly and manufacturing process of such products, the LED-integrated light-emitting module or COB light source is generally directly fixed on the radiator with screws. Due to the large tolerance of the flatness of the radiator surface, effective coaxiality positioning cannot be performed. Very large internal ...

[0002] As we all know, in order to further reduce the labor cost of assembly and manufacturing and raw material cost, most lighting assembly factories simplify the process technology and raw material performance of the indispensable materials of LED modules. Therefore, while considering the cost factor, Neglecting the most important quality issues such as product reliability, resulting in a large number of product failures during the use of end users, resulting in very large economic losses

[0003] During the assembly and manufacturing process of such products, the LED-integrated light-emitting module or COB light source is generally directly fixed on the radiator with screws. Due to the large tolerance of the flatness of the radiator surface, effective coaxiality positioning cannot be performed. Very large internal stress, such as shear stress in the normal direction of the axis, leads to dark cracks in the LED integrated light-emitting module or the PCB of the COB light source, or the safety distance becomes smaller, resulting in leakage, or due to excessive coaxiality tolerance , resulting in the optical effect failing to meet the performance requirements, etc., which greatly reduces the reliability of the LED module, and eventually leads to the failure of the LED module
