Problems solved by technology

However, in terms of the structure of the existing diffuser, the transmittance and haze are in an inversely proportional relationship, so it is difficult to increase the transmittance and haze at the same time
In addition, the light diffusion angle of existing diffusers is mostly limited to within 120 degrees, and it is not easy for the structure and manufacturing process of existing diffusers to increase the light diffusion angle.

Embodiment Construction

[0040] see figure 1 , which is a structural side view of the first preferred embodiment of the diffusion structure of the present invention. The diffusion structure 1 includes a first surface 11 and a second surface 12 opposite to the first surface 11, and a speckle (Speckle) layer 13 is formed on the first surface 11, and a grating (Grating) layer 13 is formed on the second surface 12. ) layer 14; wherein, the grating layer 14 is located between a light source 9 and the speckle layer 13, so that a plurality of light beams L1 output from the light source 9 can be output outside after passing through the grating layer 14 and the speckle layer 13 in sequence .

[0041] Furthermore, the grating layer 14 and the speckle layer 13 respectively include a plurality of gratings and a plurality of speckles. In this preferred embodiment, the gratings and the speckles are respectively distributed on the entire second surface 12 and the first The entire surface 11, but not limited to the...

Abstract

A diffusion structure and a lighting device with the diffusion structure are provided. The diffusion structure includes a first surface and a second surface. A speckle layer is formed on the first surface. A grating layer is formed on the second surface. The grating layer is arranged between a light source and the speckle layer. Consequently, plural light beams emitted by the light source are sequentially transmitted through the grating layer and the speckle layer and then outputted to surroundings. The diffusion structure has advantages of high transmittance, high haze and wide light diffusion angle, and can be applied in various devices with light sources, such as lighting devices, backlight modules, projectors, etc.

Description

technical field [0001] The present invention relates to a diffusion structure, in particular to a diffusion structure applied to a device with a light source and a device with a light source using the diffusion structure. Background technique [0002] Light Emitting Diodes (Light Emitting Diodes, LEDs) have been widely used in daily life in recent years. Because of their energy-saving benefits and advantages, displays, home appliances, automotive electronic components, lighting fixtures, etc. are all applications of light emitting diodes. category. Take household lighting fixtures that use light-emitting diodes as light sources as an example, because they have the advantages of fast warm-up time, fast response, small size, long life, power saving, shock resistance, low pollution, high reliability and suitable for mass production , so that the traditional incandescent bulbs and fluorescent lamps have gradually been replaced. [0003] However, compared with traditional light...
