Description

A high power LED lens

Technical field:

The utility model relates to the technical field of lenses, in particular to a high-power LED lens.

Background technique:

Due to the long service life of LED (Light Emitting Diode, light-emitting diode), low energy consumption, and significant energy saving, high-power, high-brightness LEDs have been widely used in daily life as light sources, such as cup lights, spotlights, car lights, etc. Lighting fixtures, when these lighting fixtures are in use, require that the light emitted by the LED is a focused beam with a certain shape. Such a focused beam must be formed by configuring a specially designed optical lens at the light outlet. In the existing lenses for high-power LEDs, a hemispherical lens with simple structure is usually used to focus and emit the light emitted by the high-power LED. However, when it is used for concentrating multiple high-power LEDs, the light emitted by multiple high-power LEDs is relatively divergent, which makes it difficult to control the light output angle and the uniformity of the light spot is poor.

Utility model content:

The purpose of the utility model is to provide a high-power LED lens suitable for multiple high-power LEDs to focus on the deficiencies of the prior art.

In order to achieve the above object, the technical solution adopted by the utility model is:

It includes an integrally formed lens body, the bottom of the lens body is formed with two or more concentrating cups, and the bottom of the concentrating cup is provided with a concave part for placing a high-power LED. The lens body A reflective cavity corresponding to the light-concentrating cup is provided on the top of the reflective cavity. The bottom end of the reflective cavity is a downwardly concave conical surface, and the bottom end of the conical surface is an upwardly convex upper spherical surface.

Wherein, the bottom end of the lens body is formed with a positioning post.

Wherein, a bump is formed on the bottom end of the focusing cup body.

Wherein, a reinforcing rib is formed between the two focusing cups of the lens body.

The beneficial effects of the utility model are:

A high-power LED lens provided by the utility model includes an integrally formed lens body, two or more light-concentrating cups are formed at the bottom of the lens body, and the bottom of the light-concentrating cup is provided with a large In the concave part of the power LED, the top of the lens body is provided with a reflective cavity corresponding to the condenser cup body. The bottom end of the reflective cavity is a downwardly concave conical surface, and the bottom end of the conical surface is an upward convex Spherical surface, since there are multiple focusing cups formed at the bottom of the lens body, and a reflective cavity corresponding to the focusing cups is provided on the top of the lens body. With the cooperation of the focusing cups and the reflecting cavity, each The light emitted by each high-power LED can be focused and reflected separately, and then emitted together, which reduces the influence of divergent light between each high-power LED, thereby ensuring that the light emitted by multiple high-power LEDs has the same light angle, and the outgoing The spots are more uniform.

Detailed ways:

The utility model will be further described below in conjunction with the accompanying drawings, as shown in Figures 1, 2 and 3, the utility model includes an integrally formed lens body 1, and the bottom of the lens body 1 is formed with two or more than two Focusing cup body 2, the bottom of the focusing cup body 2 is provided with an inner recess 3 for placing a high-power LED, and the top of the lens body 1 is provided with a reflective cavity 4 corresponding to the focusing cup body 2, and the reflective cavity The bottom end of 4 is a downwardly concave conical surface 9, and the bottom end of the conical surface 9 is an upwardly convex upper spherical surface 5. Of course, the geometric dimensions of the focusing cup body 2 and the reflective cavity 4, such as radius of curvature, internal curved surface The concave and convex conditions can be set according to different light requirements and lighting effects. It should be noted that the number of the focusing cup body 2 and the reflective cavity 4 of the lens body 1 of the present utility model can be multiple, and is not limited to the three focusing cup bodies 2 and the reflective cavity body selected for this embodiment. 4 three.

In this embodiment, the bottom of the lens body 1 is formed with a positioning post 6 to facilitate the installation and positioning of the lens in the lamp; The height of the base is the same, so that the high-power LED can just be placed in the inner recess 3 of the focusing cup body 2; a reinforcing rib 8 is formed between the two focusing cup bodies 2 of the lens body 1, so that the lens body 1 structure is more stable.

When the utility model is in use, a high-power LED is correspondingly placed in the inner concave part 3 of each focusing cup body 2. With the cooperation of the focusing cup body 2 and the reflective cavity 4, that is, the The top of the concave part 3 and the upper spherical surface 5 of the reflective cavity 4 jointly form a converging convex lens, so that the light emitted by each high-power LED can be focused separately, and reflected by the inner wall of the reflective cavity 4, and then emitted together. The influence of the divergent light between each high-power LED is reduced, thereby ensuring that the light emitted by multiple high-power LEDs has the same light angle and the emitted light spot is relatively uniform.

Of course, the above are only preferred embodiments of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the utility model patent application are included in the utility model patent application within range.
