Description

A high-power LED lighting luminaire

technical field

The utility model relates to a lighting fixture, in particular to a high-power LED lighting lighting fixture.

Background technique

At present, with the increasing tension of energy, saving energy and being practical have become the basic requirements of some modern products. Lighting fixtures are one of the most energy-consuming necessities. Among the many existing lamps and lanterns used for lighting, most of them are incandescent lamps, fluorescent lamps, gas discharge lamps, etc. The brightness of these lamps is very sufficient and brings a lot of convenience to people, but they still have the following deficiencies, such as energy utilization The efficiency is relatively low, the calorific value is large, the life is short, the maintenance cost is high and the risk of operation is relatively large. LED lamps have the characteristics of energy saving, high luminous efficiency, long life, high safety, flexible control and environmental protection, but the existing LEDs generally have insufficient luminous brightness.

Utility model content

The purpose of the utility model is to provide a high-power LED lighting luminaire, which not only saves energy but also has high luminous intensity.

The purpose of this utility model is achieved through the following technical solutions.

A high-power LED lighting light-emitting lamp of the present utility model is composed of a substrate, a PCB circuit board, and a light-emitting chip connected with a lead wire of the PCB circuit board. The utility model is characterized in that: the bottom surface of the PCB circuit board is pressed Combined with the upper surface of the substrate, the PCB circuit board is provided with at least one through hole for accommodating the light-emitting chip, and the light-emitting chip and the substrate are implanted and fixed together.

The substrate is an aluminum structure or a combined structure of aluminum and copper, using a specific shape of aluminum or a combination of aluminum and copper as the substrate can effectively solve the heat dissipation problem of the lamp, and a new manufacturing process Practical. The PCB circuit board and the substrate are pressed together with plastic. The base body is provided with a heat sink structure. The light-emitting chip is encapsulated in the through hole of the PCB circuit board with resin, and other auxiliary materials can also be used as the encapsulation material. The base body is a rectangular or circular structure, and the base body can also be set in some other geometric shapes. The luminous intensity of one LED lamp or a combined structure of multiple LED lamps can meet general lighting requirements.

The utility model has the advantages of a high-power LED lighting luminaire: energy saving, high luminous efficiency, long service life, high safety, flexible control, environmental protection and high luminous intensity.
