Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

As shown in fig. 1-4, a lens-base integrated LED light source assembly includes a base 1, a lens 2 is disposed in the middle of the upper end of the base 1, a light source groove 3 is disposed in the middle of the lower end of the base 1, a light source is disposed in the light source groove 3, connection fixing plates 4 are disposed on two sides of the base 1, and the base 1, the lens 2 and the connection fixing plates 4 are integrally die-cast and molded through a die. The PC material is molded at a high temperature of 120 ℃, the strength can reach the metal strength, the heat expansion and cold contraction deformation is small, and the stability is high.

The joint of the outer edge of the lens 2 and the base 1 is provided with an annular sheet, and the thickness of the annular sheet is 0.5-2 mm. The structure can reduce the pulling deformation of the lens on the peripheral part of the lens during the manufacturing process, and ensure the stability of the lens.

The light source comprises a plastic package mold strip 5, the plastic package mold strip 5 is packaged with two pins 6, the upper end face of the end part in any pin 6 is provided with an LED lamp bead 7, the plastic package mold strip 5 is inserted into a light source groove 3 and is bonded with the base 1, and a first glue permeation groove 8 is formed in the connecting end face of the light source groove 3 and the plastic package mold strip 5. Redundant glue can enter into the glue permeating groove, so that the plastic package membrane strip is perfectly attached to the light source groove, and the position accuracy of the LED lamp beads is guaranteed.

The side of the base 1 is provided with a pin guide groove 9 above the corresponding pin 6. After the plastic package mold strip is installed, the pins need to be bent upwards, and the pin guide grooves can play a role in positioning and guiding.
