Embodiment 1

[0047] Embodiment 1 of the present invention describes a welding-free full plug-in LED light source, such as figure 1 , figure 2 As shown, it is composed of lamp beads 1, a fixed ring lampshade for fixing the lamp beads 2, a radiator 3 mounted and fixed with the fixing ring lampshade, and a pair of positive and negative lamp pins 5 connected with the lamp beads. Such as figure 1 , Figure 8 As shown, the lamp bead includes a semicircular lamp bead lens 7, an LED chip set in the lamp bead lens, a fixed lamp holder 8 for fixing the lamp bead lens, and the lamp holder leads to a positive and negative pin 10 connected with the LED chip and the lamp holder An LED bracket 9 is provided at the bottom. The fixed lamp holder and the LED positive and negative pins are arranged in the fixed ring lampshade, the lamp bead lens protrudes out of the fixed ring lampshade, and the end surface of one end of the fixed ring lampshade protruding with the lamp bead lens is a concave arc with reflect...

Embodiment 2

[0053] In the second embodiment, on the basis of the first embodiment, the radiator and the fixed ring lampshade are changed, and the two use the buckle installation method to replace the threaded connection installation method in the first embodiment. Specifically: such as Picture 9 , Picture 10 As shown, a notch 12 is recessed around the heat sink body, the inner side wall of the fixed ring lampshade 2 is protruded with a convex notch 13 that fits 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 fixed ring lampshade, and the notch and the convex opening complete the installation of the radiator and the fixed ring lampshade. After the radiator and the fixing ring lampshade are fixedly installed, the lamp feet clamp the LED pins, and the lamp beads are also pressed against the fixing ring lampshade and install...

Embodiment 3

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

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 ring lamp 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 full 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 cap which is installed and matched 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. In the application process of high-power LED products and devices, factors such as heat dissipation, electrostatic protection, and welding have a great influence on their characteristics, and they need to be highly valued by application-side customers. [0003] Due to the current limitations of semiconductor light-emitting diode chip technology, the photoelectric conversion efficiency of LEDs needs to be improved, especially high-power LEDs, because of th...
