Description

A beaded cup-shaped LED condenser lens

technical field

The utility model belongs to the field of LED light source lighting, in particular to a condensing lens used for LED uniform illumination.

Background technique

Lighting plays an indispensable role in park attractions, interior decoration, and hall exhibitions. It has the effect of rendering the atmosphere, decorating the landscape and beautifying the environment. In order to meet the lighting needs, people still use traditional lighting fixtures. One of its main disadvantages is high energy consumption. For example, incandescent lamps, whose principle is based on converting electrical energy into internal energy and emitting light through heating, almost completely convert electrical energy into heat, resulting in insufficient brightness and short life, which are far from meeting the current low-carbon and environmental protection requirements.

Although most of the existing light sources use LED lights, they also have certain disadvantages. The light output of existing LED lamps is affected by the LED packaging technology and the lens. The general LED lamp lens makes the central light intensity of the light source high after light distribution and the divergence angle is small. However, due to the convex lens at the rear end, it is easy to cause some Chip imaging makes the light spot not a standard circle, which leads to poor light extraction efficiency and visual fatigue.

Generally, practical lamps are made in one piece. When a part is damaged, it can only be scrapped as a whole.

After a comprehensive analysis, it can be summarized as follows: the existing condenser lens has poor color spot formation, poor light efficiency, high energy consumption of the light source used, and cumbersome installation.

Utility model content

In order to overcome the above problems, the present invention provides a bead-faced cup-shaped LED condenser lens, which can form a circular uniform light spot, has good light efficiency, is environmentally friendly, and is convenient for disassembly and installation.

In order to achieve the above object, realize through the following technical solutions:

A bead-faced cup-shaped LED condenser lens, comprising a cup-shaped body, an incident surface, an outgoing surface, an assembly hole and a small step, an assembly hole is opened at the rear end of the cup-shaped body, and the bottom surface of the assembly hole is the incident surface ; The front end of the cup-shaped body is the exit surface.

The assembly hole is a tapered hole with a concave top, and the bottom surface of the assembly hole protrudes relative to the rear end of the cup-shaped body.

The incident surface and the outgoing surface are honeycomb finish layers. The side wall of the cup-shaped body is a curved surface formed by rotating an arc-shaped curve around the central axis of the cup-shaped body. The small steps are arranged along the outer edge of the cup shape.

The beneficial effects of the utility model are: (1) The light is concentrated once on the convex surface, so that the projection shape of the light spot is circular, and the divergence angle of the light in the lens is 20 degrees, and the light is irradiated intensively. (2) The honeycomb-shaped small protrusions on the incident surface improve the uniformity of light and make the spot projection uniform; (3) The light source uses LED chips, which have low energy consumption, small size, long service life and low maintenance cost. (4) Made into a single small lens, multiple ones can be combined and installed to make the lamp design simpler and more reasonable.

Detailed ways

The utility model is described below in conjunction with accompanying drawing:

As shown in Figure 1, a bead-faced cup-shaped LED condenser lens includes a cup-shaped body 2, an incident surface 5, an outgoing surface 1, an assembly hole 4 and a small step 3, and is set at the rear end of the cup-shaped body 2. The assembly hole 4 , the bottom surface of the assembly hole 4 is the incident surface 5 ; the front end of the cup-shaped body 2 is the exit surface 1 .

The assembly hole 4 is a tapered hole with a concave top, and the bottom surface of the assembly hole 4 protrudes relative to the rear end of the cup-shaped body 2 .

The incident surface 5 and the outgoing surface 1 are honeycomb finish layers. The side wall of the cup-shaped body 2 is a curved surface formed by rotating an arc-shaped curve around the central axis of the cup-shaped body 2 . The small step 3 is provided along the outer edge of the cup-shaped body 2 for fixing the lens.

The assembly hole 4 is used for placing LED light-emitting chips; the bottom surface of the assembly hole 4 forms a convex lens, which can make the light converge at 20 degrees and increase the brightness. The surface diverges. The incident surface 5 can be adapted by adjusting the size of the incident projection lens 5 according to the characteristics of the LED light emitting tube or the projection angle.

The beneficial effects of the utility model are as follows: firstly, after adopting the above-mentioned structure, a 20-degree convex lens (the incident surface 5 forms a convex lens) increases the light output efficiency, obtains uniform and bright light, and has a long irradiation distance. Second, the concave conical surface can collect and reflect the incident side light, reduce the loss of light energy, and make it get a beautiful spot effect after passing through the lens. Third, the exit surface 1 is designed as a bead surface, which can soften the light and form more various light spot effects.

The above description does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still belong to the scope of the technical solution of the present invention.
