The power supply assembly is arranged on the bottom surface of the base. The lampshade is fixed on the lower part of the base. The base is made of metal materials with excellent thermal conduction. The base is also used as a radiator. The reflecting shade is sleeved on a salient at the bottom surface of the LED supporter through a hole arranged in the center of the reflecting shade. The utility model has the beneficial effects of flat, thin and finished appearance, light weight, good radiating effect, simple structure, convenient manufacturing and processing, low cost and good reliability.

Description

A light and thin high-power LED lamp

technical field

The utility model relates to the field of decoration and lighting lamps, in particular to an LED lamp.

Background technique

Existing high-power LED lamps generally integrate reflectors and radiators in order to achieve a better heat dissipation effect. Therefore, the existing high-power LED lamps generally have a columnar shape and are relatively heavy. In recent years, there have also been some flat and thin high-power LED lamps, but they are all large matrix composite lamps made of multiple high-power LED lamps. LED lamps are bulky, clumsy in shape, and have many components, which affects product reliability and increases product cost.

Contents of the invention

The purpose of the utility model is to provide a light and thin high-power LED lamp, which solves the problems of the existing high-power LED lamps such as bulky volume, clumsy appearance, many parts of the lamp, low reliability and high cost.

The technical scheme for realizing the above-mentioned purpose is:

A light and thin high-power LED lamp, including a mounting bracket, a base, an LED bracket, an LED chip, a reflector, a power supply assembly and a lampshade, the mounting bracket is fixed on the top surface of the base, the LED bracket is fixed on the bottom surface of the base, and the LED chip Packaged on the LED bracket, the reflector is set on the protrusion on the bottom surface of the LED bracket through the hole in the center, the power supply assembly is installed on the bottom surface of the base, the lampshade is fixed on the bottom of the base, and the power supply assembly, LED bracket, LED chip 1. The reflector is enclosed in the airtight space between the lampshade and the base. The input end of the power supply assembly is provided with a zero line lead-out line and a live line lead-out line, one end of the neutral line lead-out line and the live line lead-out line passes through the base and is located outside the mounting bracket, and the output end of the power supply assembly is connected with the LED chip. The base is made of a metal material with excellent thermal conductivity, and the base doubles as a radiator, and the power supply assembly is located in the gap between the reflector and the base.

When the LED chip emits light, heat is generated, and the heat is conducted from the LED bracket to the base. The base has a large surface area and is in direct contact with the air, and the heat is quickly dissipated into the air; the base doubles as a radiator, which separates the reflector from the radiator and makes The power supply assembly is located in the gap between the reflector and the base, which can not only quickly conduct heat to the outside, but also make full use of the internal space to ensure the product is thin and beautiful, and the structure is simple and convenient for production and processing; located outside the mounting bracket One end of the zero line lead-out line and the live line lead-out line are respectively connected to the neutral line and the live line of the AC power supply, and the AC power is converted into DC power by the AC-DC converter and the voltage regulating device in the power supply assembly, and then output to provide a constant current power supply for the LED chip .

The utility model has the following beneficial effects:

1. The appearance is thin and compact, light in weight and good in heat dissipation;

2. Simple structure, convenient production and processing, low cost and good reliability.
