Description

A universal light source body for LED lighting with heat dissipation design

technical field

The utility model belongs to the technical field of LED light source lighting.

Background technique

The current fluorescent tube lighting generally adopts the method of coating the inner wall of the glass lamp tube with fluorescent material and filling the lamp tube with mercury vapor. Compared with the original tungsten filament solid light emitting method, this method has a great improvement in photoelectric conversion efficiency. It has been widely used all over the world, but the pollution of mercury metal to the environment cannot be ignored.

As a new type of high-efficiency, green and environmentally friendly luminescent material, LED has been widely used in various fields such as landscape lighting and signal display. However, there are still many technical problems in how this luminescent material can be combined with traditional lighting methods to be more widely used in the field of general lighting. There are two most important technical issues and a cost issue: the first technical issue is how to make a universal light source body so that it has versatility and interchangeability. At present, the general LED lamps only solder LED components on various types of circuit boards, and use various structures to make different types of lamps, so each is a special product, and the light source itself has no versatility. As a result, the after-sales service is difficult, and the product is not easy to popularize and apply; the second technical problem is how to make the general light source body itself have good heat dissipation, thereby reducing the light decay of the general light source body and prolonging the service life. At present, although there are also LEDs that use glass tubes or organic materials similar to the existing fluorescent tubes as the shell to form a general light source body, their appearance and use are close to traditional fluorescent tubes, but they do not effectively solve the problem of heat dissipation; the other is The cost issue, that is, how to control the production cost within a very low range on the premise of achieving the above two goals.

Contents of the invention

The utility model aims at the deficiencies of the prior art, and aims to provide a universal and interchangeable LED lighting universal light source body with heat dissipation design, which is simpler in structure, has good thermal conductivity.

The technical scheme of the utility model is as follows:

A general-purpose light source body for LED lighting with heat dissipation design, which has LED components, a printed circuit board on which the LED components are welded and installed, and wires drawn from the printed circuit board; the printed circuit board is assembled in an aluminum alloy seat , the aluminum alloy seat is groove-shaped, and there is a distance between the bottom surface of the printed circuit board and the groove bottom of the aluminum alloy seat, and an insulating and heat-conducting material is filled between the bottom surface and the groove bottom; if a single LED lamp is used, The bottom surface of the printed circuit board is welded with the LED component pins, and the space between the LED component pins and the groove bottom of the aluminum alloy seat is reserved, and is completely wrapped by the filled insulating and heat-conducting material. The general light source body is installed to a designated position through a mounting bracket, or directly installed to a designated position.

The insulating and heat-conducting material adopts insulating and heat-conducting silicone rubber or other gel-like or paste-like heat-conducting materials. The component surface of the printed circuit board is filled with waterproof insulating glue.

Advantage of the utility model:

1. The heat dissipation structure is reasonably designed on the structure of the light source body, so that when the light-emitting diode is powered on, the heat of the lamp body can be quickly transferred to the aluminum alloy seat through the heat-conducting silica gel, so that the heat can be dissipated quickly, thereby reducing the LED lamp body. The working temperature can solve the heat dissipation of LED from components to lamps as a whole, so that the light decay of LED lamps can be effectively controlled, thereby prolonging the service life of LED lamps. According to experiments, it is shown that the light decay of the light emitting diode can be reduced by 50%-80% due to the solution of heat dissipation.

2. Different from other LED light source application methods, since the light source body has an independent heat dissipation structure, it adopts a card holder installation form, and standard connectors are used to connect with the power supply. Therefore, several fixed standard sizes can be designed and applied in In various types of lamps, there is no need to design a light source body for each lamp, so it has good versatility and interchangeability. This universal light source body can be used as a standard general light source body, and it can be directly applied to various types of lamps with various types of standard power sources (12V, 24V, 110V, 220V, etc. AC and DC), and can be used in different environment. It solves the disadvantages that general lamp manufacturers use LED components to make products with inconsistent specifications, no interchangeability, and difficult after-sales service when developing LED lamps. It makes the maintenance and replacement of LED lamps as convenient for users as traditional lamps.

3. The structure is simple, the manufacturability is good, and the qualification rate is high, which reduces the manufacturing cost of LED application lamps and lanterns, and is easy to install, making it more widely applicable to the market.
