Abstract

A lighting device is provided with a lamp source subassembly and a lamp shell, wherein the lamp source subassembly is provided with a plurality of first light sources and at least one diffraction optical subassembly; a diffraction grain pattern is formed by the diffraction optical subassemblies; each diffraction optical subassembly is provided with a light entering side and a light exiting side; the first light sources provide incident light for the light entering sides of the diffraction optical subassemblies; and the light shell receives light emitted from the light exiting sides of the diffraction optical subassemblies.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an illuminating device with a diffractive optical component. Background technique [0002] In the current lighting device, in order to make the light output uniform or generate a specific pattern, a fog lamp housing or an integrally formed patterned lamp housing is often used. Fogged lamp housings are generally used for general household lighting or office lighting, while one-piece patterned lamp housings are often found in car lights to provide specific stripes or geometric patterns. [0003] However, the light extraction efficiency of the frosted lamp housing is poor, and the integrally formed patterned lamp housing cannot provide a uniform visual pattern - the observer can easily see multiple separated lamps through the integrally formed patterned lamp housing source. [0004] In order to solve the aforementioned problems, a novel lighting device is required. Contents of the inven...
