Problems solved by technology

However, the luminous principle and luminous pattern of LED are very different from the current light sources such as bulbs and tubes.
Therefore, when applied to lighting fixtures, there will be problems of uneven light source or poor light extraction efficiency.

Embodiment Construction

[0136] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0137] In the present invention, a relatively low refractive index layer is used with a surface structure to produce a light-emitting module and a uniform light structure with a uniform light field and high penetration effect. In addition, the geometric optical deflection mechanism (high refractive index layer sandwiched by a low refractive index layer) is used to reduce the total reflection inside the uniform light structure, thereby improving the light extraction efficiency of the uniform light structure and the light emitting module.

[0138] In the following description, "first" and "second" are only used to indicate two components (two surfaces, two material layers or two substrates), and are not used to limit specific components or order.

Abstract

The invention discloses a light uniformization structure and a light emitting module, wherein the light uniformization structure includes a first material layer having a plurality of microstructures in a surface thereof, a second material layer having a plurality of microstructures in a surface thereof, and a spacer layer. The spacer layer is located between the first material layer and the second material layer, and a refractive index of the spacer layer is smaller than a refractive index of the first material layer and a refractive index of the second material layer. According to the light uniformization structure and the light emitting module in the invention, a relatively-low refractive index layer matched with the surface structure is used to generate uniform light field and high penetration effect. What's more, a geometrical optic deflection mechanism (a high refractive index layer clamping a low refractive index layer) is used to reduce total reflection in the internal of the light uniformization structure, further improving light-outgoing efficiency of the light uniformization structure and the light emitting module.

Description

technical field [0001] The invention relates to a light source module, in particular to a uniform light structure and a light emitting module. Background technique [0002] Because light emitting diodes (light emitting diodes, LEDs) have excellent characteristics such as small size, energy saving and long life, they are the most energy-saving and carbon-reducing effects among all new light-emitting components. In recent years, LEDs have been widely used in lighting devices. And, as the awareness of green energy rises, lighting devices using LEDs are expected to gradually replace current lighting fixtures. However, there are great differences in the light-emitting principle and light-emitting pattern of LEDs and current light sources such as bulbs and lamp tubes. Therefore, the problem of uneven light source or poor light extraction efficiency will occur when it is applied to lighting fixtures. Contents of the invention [0003] In view of the above problems, the main pu...
