Description

LED lamp head structure

technical field

The utility model relates to a lighting fixture, in particular to an LED lamp head structure.

Background technique

LED lamp holders appeared in the 1960s. Since then, people have hoped that one day LED lamp holders can replace traditional light bulbs, but to realize this dream, two problems must be solved, namely, high power output and lifespan. The solution to this problem depends on the solution to the heat dissipation problem of the LED junction. However, in the prior art, as shown in Figure 1, although the back cover 1` of the LED lamp is provided with cooling holes, there is only a flat lamp holder 3` inside the back cover, and on the lamp holder 3` The disadvantage of installing LED lamp components is that the space between the lamp holder 3` and the rear cover 1` is too small, the air flow is not smooth, resulting in poor heat dissipation, thereby reducing the luminous efficiency of the LED lamp and shortening the life of the LED lamp. life. In addition, most of the LED lamps currently used are illuminated by a single LED lamp in a straight line. The light is too concentrated, which is prone to blind spots and damages the eyes. However, most of the diffused LED lamps in the prior art adopt a lamp cover with a lens, and the structure is complicated.

Utility model content

The purpose of the utility model is to overcome the defects in the prior art, and provide an LED lamp head structure with a larger space between the lamp frame and the rear cover, thereby enhancing the air flow.

Another object of the present utility model is to provide a diffuse light LED lamp head structure with a simple structure.

In order to achieve the above object, the technical solution provided by the utility model is as follows: Construct a LED lamp head structure, including a rear cover, a lamp cover, a lamp holder installed between the rear cover and the lamp cover, and several LED lamps fixed on the lamp holder Assemblies, the lamp holder includes a hollow cone, a platform facing the lamp cover is formed at the top of the hollow cone, and a through hole is arranged on the platform, and the hollow cone is divided into several gaps uniformly distributed on the cone surface. In the fan-shaped ring area, the plurality of LED lamp assemblies are respectively fixed on the fan-shaped ring-shaped area, and the rear cover and the lamp cover are respectively provided with cooling holes.

The lamp cover has an arc shape matching the hollow cone, and several sandblasting belts are evenly distributed on it.

The sandblasting belts are arranged radially around the top of the arc surface of the lamp cover.

The lamp holder is in close contact with the outer edge of the rear cover, both of which are aluminum or copper components.

The platform is at an angle of 20°-70° to the conical surface.

The hollow cone is a polygonal pyramid or a cone.

The beneficial effects of the utility model are: since the lamp frame is a hollow cone, the space between the lamp frame and the rear cover is large, the lamp frame and the rear cover are in close contact, there is a gap on the cone surface of the hollow cone, and the front end of the cone There are through holes on the platform, and there are also through holes on the back cover and lampshade, forming a smooth heat dissipation channel, which greatly enhances the heat dissipation capacity of the LED lamp head, thus effectively ensuring the luminous efficiency of the LED lamp and prolonging the life of the LED lamp . At the same time, the sandblasting strips are arranged radially around the top of the arc surface of the lamp cover. This sandblasting has the function of reflecting and refracting light, so that the LED lamp can emit soft diffuse light.

Detailed ways

The structure of the LED lamp head of the present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments:

Referring to Fig. 2, Fig. 3 and Fig. 4, an LED lamp head structure is provided, including a rear cover 1, a lamp cover 2, a lamp holder 3 installed between the rear cover 1 and the lamp cover 2, and a 6 fixed on the lamp holder 3. A LED lamp assembly 4, the lamp holder 3 is a hollow cone 30, the hollow cone 30 can be a polygonal cone or a cone, what this embodiment uses is a polygonal cone, and the top of the hollow cone 30 is formed towards the lamp cover 2 The platform 31 is provided with a through hole 34, the hollow cone 30 is divided into 6 fan-shaped ring-shaped areas 33 by 6 gaps 32 evenly distributed on the cone surface, and the 6 LED lamp assemblies 4 are respectively fixed on the 6 On the fan ring area 33 , the platform 31 and the conical surface form a 20°-70° angle, and the lamp holder 3 is in close contact with the outer edge of the rear cover 1 , both of which can be made of aluminum or copper. The rear cover 1 and the lamp cover 2 are respectively provided with cooling holes 10 and 20 . Because the lamp holder 3 is a hollow cone and is in close contact with the rear cover 1, the space between the lamp holder and the rear cover is relatively large. There are also through holes on the rear cover and lampshade, forming a smooth heat dissipation channel, which greatly enhances the heat dissipation capacity of the LED lamp head, thereby effectively ensuring the luminous efficiency of the LED lamp and prolonging the life of the LED lamp.

Referring to FIG. 5 , the lamp cover 2 has an arc shape matching the hollow cone 30 , and several sandblasting belts 21 are evenly distributed on it. The sandblasting belts 21 are radially arranged around the top of the arc surface of the lamp cover 2, and the light emitted by the LED lamp assembly is reflected by the sandblasting belts 21, and then leaks out from between the sandblasting belts 21 to form soft diffuse light.
