Description

LED fixing device

Technical Field

Background

After the LED template 90 is placed on the first fixing seat 70, a second fixing seat 80 is placed above the LED template 90 and covers the LED template 90, in other words, the LED template 90 is sandwiched between the first fixing seat 70 and the second fixing seat 80, the second fixing base 80 includes a base 81 and a joint 83, the joint 83 is disposed on one side of the base 81, a receiving slot 810 is formed on the base 81, a plurality of position-limiting pieces 84 and two electrical connection pieces 85 are disposed in the receiving slot 810, the two electrical connection pads 85 are respectively disposed on two opposite sides of the receiving slot 810, and the positions thereof correspond to the two electrode contacts 95 of the led template 90, and the other ends of the two electrical connection pads 85 extend into the connector 83, a terminal 86 is formed in the electrical connection pad 85 inside the connector 83; after the second fixing base 80 is covered on the led template 90, the two electrical connection pads 85 respectively press down against the two electrode contacts 95 of the led template 90 to electrically connect the substrate 93 and the terminals 86, and meanwhile, after the second fixing base 80 is covered, the limiting pads 84 abut against the ceramic circuit board 91, so that the entire led template 90 cannot be separated from the second fixing base 80.

The fixing method of the prior art that fixes the led template 90 by the first fixing seat 70 and the second fixing seat 80 has the following disadvantages.

First, the second fixing base 80 covered on the LED template 90 has a larger volume, a longer length, and a thinner and longer central portion, which is prone to stress problem during use and further causes dimensional deformation.

Second, after the led template 90 is placed on the first fixing base 70, in the process of covering the second fixing base 80, since the vertical downward covered track has no locatable element, the limiting sheet 84 and the two electrical connection sheets 85 of the second fixing base 80 may scratch the led die on the substrate 93 in the misalignment condition.

Thirdly, the positioning studs 72 of the first fixing seat 70 are integrally formed on the first fixing seat 70, in other words, when the first fixing seat 70 is processed, the small positioning studs 72 need to be further cut, and in the processing procedure, the volume is too small, so that the residual glue is easily formed.

Fourth, the small positioning studs 72 are easily broken or damaged during manufacturing or after a period of use, which results in the failure to accurately position the led template 90 and the loss of positioning function.
