New description: [New technical field] This creation is a diffusion structure, especially regarding a diffusion structure applied to a device having a light source. • [Prior Art] Light Emitting Diode (LED) has been widely used in everyday life because of its advantages and advantages of energy saving and power saving, such as displays, home appliances, automotive electronic components, Lighting fixtures, etc. are all applications of light-emitting diodes. For example, a household lighting fixture using a light-emitting diode as a light source has the advantages of fast warming time, fast response speed, small volume, long life, power saving, shock resistance, low profitability, flexibility and suitability. The advantages of mass production have led to the tendency of traditional white-woven bulbs and neon lamps to be gradually replaced. However, the light-emitting diode has better directivity compared to the conventional light source. Therefore, when a plurality of light-emitting diodes simultaneously output light, the user feels

It is well known in the art. As far as people are aware, they will not be repeated here. Furthermore, the industry currently has two major demands for the performance of the diffuser: the first is the penetration rate, which is the ability of the light provided by the light-emitting diode to penetrate the diffuser, which affects the illumination device. Brightness; the second is haze, the ability of "point" luminescence to convert to "face" luminescence. However, in terms of the structure of the existing diffuser plate, the transmittance and the haze are approximately inversely proportional, so it is difficult to simultaneously increase the transmittance and the haze. In addition, the light diffusing angle of the existing diffusing plate is limited to only 丨2〇, and the right to increase the light diffusing angle is not easy for the structure and process of the existing diffusing plate. Therefore, the conventional diffuser plate still has room for improvement. [New content] The main purpose of this creation is to provide a diffusion structure, especially for a diffusion structure with high dispersion rate, high haze and wide light diffusion angle. Another object of the present invention is to provide a device having a light source for applying the above-described diffusion structure.
