Abstract

The invention discloses an optical lighting device and optical modification equipment, the optical lighting device comprises two line light sources and a scanning reflection part, the scanning reflection part is provided with two reflection surfaces, each line light source is provided with a light modulation part, and the light modulation part is provided with a light source. The light modulation component is used for modulating light rays emitted by the line light source into parallel light and homogenizing the parallel light to form light bands with set lengths, and the two reflecting surfaces are respectively used for receiving the two light bands and reflecting the two light bands to a working surface of the same processing piece; the device further comprises a driving part, the driving part is used for driving the scanning reflection part to move in a reciprocating mode in the set direction, and the set direction is parallel to the working face. The structural arrangement of the optical lighting device can improve the local irradiation energy density, so that the total auxiliary energy borne by different areas of the target working face is relatively uniform, and meanwhile, the productivity can be improved.

Description

technical field

[0001] The invention relates to the technical field of optical modification treatment, in particular to an optical lighting device and optical modification equipment. Background technique

[0002] The optical modification of thin films in the semiconductor industry, or the optical modification of thin films in the LED and flat panel display industries, is usually carried out using optical modification equipment.

[0003] Taking ultraviolet light modification equipment as an example, its ultraviolet lighting device generally adopts the scheme of surface light source to assist the rotation of the lighting head. In engineering design, one or two ultraviolet lamp tubes are used as the light source to cooperate with the optical path design to achieve the effect of surface light source. The irradiance intensity of such a surface light source on different areas of the target working surface is very different, and the time integral of the local light intensity on the...
