Description

A new LED light distribution structure

technical field

The utility model relates to a lighting device, in particular to a novel light distribution structure of an LED lamp.

Background technique

Traditional ceiling lamps generally use ring-shaped fluorescent lamps as light sources, and the lights are all irradiated downwards. At present, LEDs have the advantages of long life, high luminous efficiency, energy saving and environmental protection, etc., and it is imperative for LEDs to replace traditional fluorescent lamps as the ceiling lamp as the light source. However, the LED ceiling lamps currently on the market generally have a single light distribution form, and all use lamps to illuminate downwards. They are simply ceiling lamps that simply replace traditional circular fluorescent lamps as light sources.

With the development of the economy, lighting design has not only focused on brightness at the beginning, but now it is not only pursuing brightness, but also pursuing light quality, that is, in the process of lighting design, factors such as surrounding light environment, human emotions and convenience should be integrated. go in. At present, LED ceiling lamps are mostly used in indoor homes. In order to create a light environment for the entire space, customers usually need to import a variety of lamps to achieve it. In terms of cost, installation and application convenience, this solution is not the best choice.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a new LED lamp light distribution structure with simple structure, convenient assembly, low production cost and good light distribution effect.

The purpose of this utility model is achieved in the following manner: a novel LED lamp light distribution structure, which is characterized in that it includes a lens for refracting the light source, and several LED lamps arranged on the outer edge of the lens, and the light emitting of the LED lamp The surface is set close to the outer edge of the lens, so that the light emitted by the LED lamp enters it from the outer edge of the lens, and the light-emitting surface of the lens is covered with a uniform light plate.

The lens is a concave lens.

The lens is a convex lens.

The outer edge of the lens is provided with a platform that is in contact with the light-emitting surface of the LED lamp.

The several LED lamps are welded on the flexible circuit board and electrically connected with the power supply.

The dodging plate is a frosted plexiglass plate.

The dodging plate is an atomized glass plate.

The beneficial effects of the utility model are: 1) The structure is simple, the assembly is convenient, the production cost is low, and the market competitiveness is improved. 2) The light enters from the side wall of the lens, which changes the transmission line of the light, so that the light can be refracted and transmitted in the lens for many times, so that the light is more uniform, soft and not dazzling. 3) It can be equipped with a convex lens for scattering light distribution, so that the light irradiation range of the structure is wider. 4) Concave lens can be used for concentrated light distribution, so that the effect of light distribution is more concentrated and the brightness is higher, which is suitable for searchlights and other uses.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is specifically further described. A new LED light distribution structure, characterized in that it includes a lens for refracting light sources, and a number of LED lights 1 arranged on the outer edge of the lens, the light-emitting surface of the LED lights 1 is arranged close to the outer edge of the lens, The light emitted by the LED lamp 1 is injected into the lens from the outer edge, and the light-emitting surface of the lens is covered with a uniform plate 2 .

Described lens is concave lens 3.

Described lens is convex lens 4.

The outer edge of the lens is provided with a platform 5 that is in contact with the light-emitting surface of the LED lamp 1 .

The plurality of LED lamps 1 are welded on the flexible circuit board 6 and electrically connected with the power supply.

The dodging plate 2 is a frosted plexiglass plate.

The dodging plate 2 is an atomized glass plate.

Working principle: In this utility model, according to different lighting environments, a concave lens can be used for concentrating light distribution, and a convex lens can also be used for astigmatism light distribution, so as to meet the needs of various lighting environments such as large-scale lighting or local searchlighting. In order to achieve a more uniform, soft and high-efficiency light distribution effect, the LED lights in this case are distributed in a circular array and installed on the outer edge of the lens. The light-emitting surface of the LED lamp is arranged close to the outer edge of the lens. When the LED lamp is working, the light emitted by it is projected into the interior through the outer edge of the lens. Different from the light distribution method in which the traditional LED light is installed at the bottom of the lens, the light in this case needs to be refracted many times in the lens before being projected out, and the light emission direction of the LED light is also different from the final light projection direction of the lens, so The projected effect of the light after multiple refractions is more soft and uniform, without the defects of traditional LED lighting such as spot and glare, so it can be widely used in LED downlights, ceiling lights and other places. the

The above-mentioned embodiments are only to illustrate the technical conception and characteristics of the present utility model. Equivalent changes or modifications made in the spirit of the invention shall fall within the protection scope of the present invention.
