Embodiment 1

[0047] A solder-free fully pluggable LED light source described in Embodiment 1 of the present invention, such as figure 1 , figure 2 As shown, it consists of a lamp bead 1, a lampshade 2 with a fixed ring for fixing the lamp bead, a heat sink 3 fixed with the lampshade of the fixed ring, and a pair of positive and negative lamp pins 5 connected with the lamp bead. Such as figure 1 , Figure 8 As shown, the lamp bead includes a semi-circular lamp bead lens 7, an LED chip arranged in the lamp bead lens, a fixed lamp holder 8 for fixing the lamp bead lens, and the lamp holder is led out with positive and negative pins 10 connected with the LED chip and the lamp holder The bottom is provided with an LED bracket 9 . The fixed lamp holder and the positive and negative pins of the LED are set in the lampshade of the fixed ring, the lamp bead lens protrudes outside the lampshade of the fixed ring, and the end face of the lampshade of the fixed ring protruding from the lamp bead l...

Embodiment 2

[0053] In Embodiment 2, on the basis of Embodiment 1, changes are made to the radiator and the lampshade of the fixed ring, and the installation method of the two is snapped instead of the threaded connection installation method in Embodiment 1. Specifically: if Figure 9 , Figure 10 As shown, a notch 12 is recessed around the heat sink body, and the inner wall of the fixed ring lampshade 2 is protruded with a convex notch 13 fitted with the notch, and the end surface of one end of the fixed ring lampshade protruding with a lamp bead lens is reflective Arched arc surface; when installing, directly push the heat sink body of the radiator 3 into the lampshade of the fixed ring, and the installation of the radiator and the lampshade of the fixed ring is completed after the notch cooperates with the convex notch. After the heat sink and the lampshade of the fixing ring are fixed and installed, the lamp pins clamp the LED pins, and the lamp beads also press the lampshade of the f...

Embodiment 3

[0055] This embodiment 3 also makes changes on the basis of embodiment 1, specifically: as Figure 11 , Figure 12 , Figure 13 As shown, the insulating plastic rubber sleeve 4 is an integrated structure, and the insulating plastic rubber sleeve is composed of a symmetrical fan-shaped packing body and a snap ring 6 connected between the two fan-shaped packing bodies, and the lamp pins pass through the corresponding insulating plastic rubber sleeve; The connecting terminal at the end of the lamp pin is a contact copper sheet 18 that fastens the LED pin, the contact copper sheet is arranged in an insulating plastic rubber sleeve, and the contact copper sheet is provided with a card slot that allows the LED pin to be inserted into the contact copper sheet 19. The diameter of the card slot is smaller than the diameter of the LED pin; the outer diameter of the contact copper sheet is larger than the outer diameter of the lamp pin. The outer diameter of the snap ring 6 is greater ...

Abstract

The invention discloses a welding-free full-insertion-type LED (light-emitted diode) light source, consisting of a lamp bead, a fixed ring lamp shade, a radiator and a lamp foot, wherein the light bead comprises a lamp bead lens, an LED chip, a fixed lamp holder, a positive pin, a negative pin and an LED support; the fixed lamp holder, the positive pin and the negative pin are arranged in the fixed ring lamp shade; and the lamp bead lens protrudes out of the lamp bead lens. A traditional welding mode is replaced by the connecting mode of threads or fasteners of the radiator and the fixed ringlamp shade, so that the contact of the radiator and the fixed ring lamp shade is realized by the lamp foot and the LED pin in a full insertion type, and the traditional welding mode of the radiator and the fixed ring lamp shade is omitted. For the LED light source, the volume is small, and the largest outer diameter of a largest part, namely the radiator, is only 15mm. The rated current of the lamp bead is 300mA, the rated voltage of the lamp bead ranges from 3.2V to 3.6V, the lightness of the lamp bead is higher than 100 lumen (LM), and the luminance of the light source is enough. In addition, the invention relates to the installation method of the LED light source and a connection lamp holder matched with the LED light source for installing.

Description

technical field [0001] The invention relates to an LED light source, in particular to a welding-free fully plug-in LED light source with sufficient brightness and simple structure; in addition, it also relates to an installation method of the LED light source and a connecting lamp holder for installation and cooperation with the LED light source. Background technique [0002] With the rapid development of LED technology, LED street lamps, projection lamps and other devices are developing towards high power, compactness and light weight. During the application process of high-power LED products and devices, factors such as heat dissipation, electrostatic protection, and welding have a great impact on their characteristics, which need to be highly valued by application-side customers. [0003] Due to the limitations of current semiconductor light-emitting diode chip technology, the photoelectric conversion efficiency of LEDs needs to be improved, especially for high-power LEDs...
