In order to achieve the above object, the utility model mainly adopts the following technical solutions:

A high-power LED spotlight, comprising a lamp head assembly, a spotlight cup located in the lamp head assembly, and an LED lamp installed in the spotlight cup, wherein the lamp head assembly is composed of an insulating shell, a metal upper cover and a metal lower cover, The metal upper cover is installed between the insulating case and the metal lower cover.

The insulating shell is provided with a clasp, and the metal lower cover is provided with a buckle corresponding to the clasp, and the insulating shell and the metal lower cover are connected with the clasp through the clasp.

A high-frequency switching power supply with an isolation transformer is also installed inside the insulating case.

An LED lamp board is also installed in the lamp head assembly, and a constant current driving power supply is welded on the LED lamp board.

The metal upper cover is also provided with a plurality of cooling holes.

The insulating shell is also provided with pins electrically connected to the constant current driving power supply on the LED lamp board.

The LED light board is fixed inside the metal upper cover.

The utility model not only effectively solves the problems of heat dissipation of existing high-power LED spotlights and great harm to human body, but also reduces the The cost of the whole product is reduced. In addition, the utility model also has the advantages of simple structure and convenient installation.

Description of drawings:

Fig. 1 is a three-dimensional schematic diagram of the utility model.

Fig. 2 is a schematic diagram of the combined structure of the utility model.

Instructions in the figure: insulating shell 1, insulating cover plate 2, metal upper cover 3, LED light board 4, metal lower cover 5, LED light 6, clasp handle 7, constant current drive power supply 8, buckle 9, spotting cup 10. Pin 11.

Detailed ways:

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 to 2, a high-power LED spotlight includes a lamp cap assembly, a focusing cup 10 located in the lamp cap assembly, and an LED lamp 6 installed in the focusing cup 10, wherein the lamp cap assembly mainly It consists of an insulating case 1 , a metal upper cover 3 and a metal lower cover 5 , and the metal upper cover 3 is installed between the insulating case 1 and the metal lower cover 5 .

The base end of the above-mentioned insulating case 1 is provided with two openings, and pins 11 that can be directly connected to the alternating current are installed in the openings. An isolation transformer power supply is installed inside the insulating case 1. When a short-circuit fault occurs, the isolation transformer power supply is It is isolated from the AC circuit through the insulating case 1, so the safety of the user can be guaranteed. In addition, the lower end of the insulating case 1 is provided with three clasps 7, the metal upper cover 3 is provided with openings corresponding to the clasps 7, and the metal lower cover 5 is provided with buckles 9 corresponding to the clasps 7. , pass the clasp 7 on the insulating case 1 through the opening on the metal upper cover, and then rotate and fix it with the buckle 9 on the metal lower cover 5. Here, the insulating case 1 and the metal lower cover 5 can also be connected by screws and other fixedly connected together. In addition, an insulating cover plate 2 is installed inside the lamp head assembly. The insulating cover plate 2 is fixed in the insulating shell 1, and there is a hole for fixing wires at its edge. The LED lamp board 4 is fixed on the metal upper cover 3 and the metal lower cover. Between the covers 5 , a constant current driving power supply 8 is also provided on the LED lamp board 4 .

The metal lower cover 5 is provided with a spotlight cup 10, the spotlight cup 10 can be one or more, the utility model is preferably one, the spotlight cup 10 is located in the center of the metal bottom cover 5, and the spotlight cup 10 High-power LED lamp 6 is installed in 10, and described LED lamp 6 is electrically connected with constant current driving power supply 8, and constant current driving power supply 8 is connected with pin 11 by wire, and pin 11 is directly connected with 220VAC or 110V.

In addition, the metal upper cover 3 described in the utility model is also provided with a plurality of openings, because the high-power LED lamp 6 will generate a lot of heat during the working process, if the heat dissipation is not timely, it may cause the constant current drive power 8 and the LED light board 4 are damaged, so it is necessary to dissipate heat through the metal upper cover 3 and the insulating shell 1. The utility model adopts the combination of the metal upper cover 3 and the insulating shell 1, which is not only cost-effective but also uses the whole metal as the shell. The lamp should be lower, and it is easier to dissipate heat. In addition, the combination of this structure is simple in structure, and it is relatively simple to install and disassemble when replacing the LED lamp board.

A kind of high-power LED spotlight described in the utility model has been introduced in detail above. In this paper, specific examples are used to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model.
