Abstract

The invention provides an optical assembly and a lighting device and a table lamp using the same, and the optical assembly comprises a mounting part for mounting a light source; the light reflecting part is arranged on a light path of the light source; the light emitting part is arranged on a light path of the light source and comprises a sawtooth structure; wherein the mounting part is arranged between the light reflecting part and the light emitting part, and part of light emitted by the light source is reflected by the light reflecting part and then is irradiated out through the sawtooth structure, so that the illumination of the light source is uniform. The illumination uniformity of the table lamp is improved, meanwhile, the blue light harm of the table lamp is reduced, the photo-biological safety of the table lamp is greatly improved, the use experience of a user is improved, and eye health of the user is better guaranteed. Moreover, the LED lamp has good heat dissipation performance and insulation performance, long service life and high use safety, all the components are simple in structure, convenient to assemble, easy to produce and manufacture and convenient to popularize and use, and the LED lamp has extremely high economic value and social value.

Description

technical field [0001] The present invention relates to the field of optics, in particular to an optical assembly and an applied lighting device and desk lamp. Background technique [0002] As the main lighting tool for people's daily work, study and reading, table lamp includes various performance requirements such as shading, illuminance and illuminance uniformity. According to the performance requirements of GB-T 9473-2017 reading and writing work desk lamps, AA-level illuminance requires that the illuminance of 120° fan-shaped area of ​​0-300mm is not less than 500lx, and the illuminance of 120° fan-shaped area of ​​300mm-500mm is not less than 250lx; AA-level illuminance is uniform It is required that the ratio of the maximum illuminance to the minimum illuminance in the two 120° fan-shaped areas of 0-300mm and 300mm-500mm is not greater than 3. In the existing AA-level eye protection table lamp products, the ratio of illuminance is generally greater than 2 and close t...
