Abstract

The present invention discloses a table lamp with glare preventing function. The table lamp comprises a table lamp main body, a light source and a microstructure light control component. The light source and the microstructure light control component are arranged on the table lamp main body. The microstructure light control component is formed by combining a Fresnel microstructure and a light control structure component. The Fresnel microstructure is used for dispersing or bunching light rays provided by the light source. The dispersing structure is used for controlling the projecting direction of the light rays so as to achieve the aims of preventing the production of the glares and enhancing the uniformity of luminescence.

Description

technical field [0001] The present invention relates to a desk lamp with anti-glare function, in particular to a light control microstructure composed of a Fresnel-like microstructure and a diffusion structure to control the light distribution and direction without detracting from the light output. Efficiency, thereby achieving a desk lamp that prevents glare and increases the uniformity of light emission. Background technique [0002] There are three common types of glare: direct glare, contrast glare, and reflected glare; direct glare is the glare that the eyes feel when they look directly at the light source, such as looking directly at the sun or the lights of cars approaching at night, and direct glare when reading means looking directly at the lamp tube When the light-dark ratio of two different light sources in the room (such as the main light on the ceiling and the desk lamp used for reading on the table) is too large, contrasting glare will be produced; and reflecte...
