Dot arrangement structure of flat lamp light guide plate with high light emission rate

Abstract

The invention belongs to the technical field of illumination and particularly relates to a dot arrangement structure of a flat lamp light guide plate with a high light emission rate. The structure comprises a light guide plate body, and two opposite edges of the light guide plate body are sides with light sources. From the sides with light sources to a symmetrical center line of the light guide plate, the diameters of dots on the light guide plate body are increased in order according to a growth function, and the growth function is Y=K / (1+e^(a+bx)). The dot arrangement structure has the advantages that through a dot design scheme of the growth function, after the two sides of the light guide plate body emit light, the light is scattered by the dots on a scattering surface, the light emitted from a plane opposite to the scattering surface is uniform, and a light emission rate is largest. According to the size of the light guide plate body, in a short time, with a certain value of a distance between two adjacent dots, an optimal dot arrangement structure is obtained, a long-term test is not required, and the research and development and production efficiencies are improved.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a dot layout structure of a light guide plate of a flat panel lamp with a large light output rate. Background technique [0002] The light guide plate is the key optical device of the flat panel light. Its function is to guide the light emitted by the side-emitting light source through the light guide plate, from the side to the light-emitting direction, through multiple light changes such as incident, refraction, reflection, and diffuse reflection. , and become a direct light relative to the plane of the flat panel light, thereby illuminating the surrounding environment. Therefore, the working efficiency of the light guide plate is related to the light use efficiency of the entire lamp. In order to improve the light guide efficiency of the light guide plate, dots are designed on one side of the light guide plate. Under the influence of the dots, the light direction...

Problems solved by technology

But because there is no theoretical guidance, it is impossible to obtain the maximum light output solution

[0004] 2. Because it is a human experiment, the number of experiments is always limited, so it is impossible to obtain the best network solution in a short period of time

[0005] 3. Many artificially tested structures often have a low light output rate
