CN204227325U - A new type of LED circular light guide plate - Google Patents

Abstract

The embodiment of the utility model discloses novel circular light guide plate of LED, it includes a transparent or translucent plate body, this plate body's a side terminal surface is equipped with a LED banks at least, plate body surface or form unsmooth V type groove on the optical sheet of stromatolite on plate body, unsmooth V type groove is circular line, encircle the central point, the launching source, reduce bright loss, this product surface is bright and clean, point source or line source are arranged to periphery in light guide plate one side or side, encircle the central point, the launching source, the loss of luminosity reduction luminance is concentrated to bigger degree ground, compensate a series of defects that the product on the market produced before.

Description

A new type of LED circular light guide plate

technical field

The utility model relates to the field of light guide plates, in particular to a novel LED circular light guide plate. the

Background technique

The existing LED light guide plate has simple structure, low utilization rate of light source, and increased use cost. the

Utility model content

The technical problem to be solved by the embodiment of the utility model is to provide a new type of LED circular light guide plate with high light source utilization rate. the

The novel LED circular light guide plate includes a transparent or translucent plate-shaped body, at least one LED light group is provided on one side of the plate-shaped body, and the surface of the plate-shaped body is laminated on the plate-shaped body. Concave-convex V-shaped grooves are formed on the optical sheet on the main body, and the concave-convex V-shaped grooves are circular patterns, which surround the center point, emit light sources, and reduce the loss of light. the

On the reflecting surface opposite to the emitting surface, two inclined surfaces formed along the direction perpendicular to the incident surface are repeatedly arranged. the

Implementation of the utility model embodiment has the following beneficial effects:

The utility model embodiment is a new type of LED light guide plate. The product material includes a transparent or translucent plate-shaped body. LED lamp groups are arranged on the side and end faces of the plate-shaped body, which effectively destroys the light intensity directivity of the LED lamp group and makes the light rays cross each other. Interference, so as to spread evenly to the whole body, so that the body produces a uniform divergent plane light source. This patent is to make the concave-convex card groove into a circular pattern, surround the center point, emit light source, reduce the loss of light, concentrate the luminosity, and comprehensively improve the product. Brightness, convert the point light source of the LED lamp group into a surface light source, more effectively improve the light utilization rate, enhance the brightness to a greater extent, reduce the use of LED point light source, save the cost of light source and reduce the power consumption of the product; In addition, this product has a simple structure and is suitable for more occasions, expanding the scope of application of this type of product.

Fig. 1 is a structural schematic diagram of an embodiment of the utility model. the

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings. the

The new LED circular light guide plate according to the embodiment of the utility model includes a transparent or translucent plate-shaped body 1. At least one LED lamp group is provided on one side of the plate-shaped body 1, and the surface of the plate-shaped body may be stacked. The concave-convex V-shaped groove 2 is formed on the optical sheet on the plate-shaped body. The concave-convex V-shaped groove is a circular pattern, which surrounds the center point, emits light source, and reduces the loss of light. On the reflective surface opposite the emitting surface, it is perpendicular to the incident surface Two inclined surfaces formed along the direction perpendicular to the incident surface are repeatedly set. the
