Abstract

The present invention provides an irradiation device capable of adjusting the emitting angle of light and stably maintaining the adjusted emitting angle of light. The irradiation device of the invention comprises: a light source (21); a light source holding part (22), which holds the light source; a collimating lens (23), which allows the light beam from the light source to be incident; a lens holding part (24), which holds the collimating lens; And a fastening part (27), which is fastened to the lens holding part to fix the positional relationship between the light source and the collimating lens. The characteristic of this illuminating device is that, between the light source holding part and the fastening part, there is a gap (222) in the direction perpendicular to the optical axis of the collimating lens. Parallel movement in the direction perpendicular to the optical axis.

Description

technical field [0001] The invention relates to an irradiation device, a discharger and an adjustment method of the irradiation device. Background technique [0002] There is known an irradiation device that converts diffused laser light emitted from a laser source into a parallel beam by a collimator lens, diffuses the parallel beam in a predetermined direction by an irradiation element, and projects light onto a surface to be projected. This type of irradiation device is used as an irradiation device of a line beam that can irradiate an object with linear laser light in a vertical direction or a horizontal direction. [0003] When the positional relationship between the laser source, the collimating lens, and the irradiating element is misaligned, the optical axis of the emitted light beam from the irradiating device will be inclined toward the main body of the irradiating device. Therefore, there is a need for an irradiation device capable of adjusting the inclination of...
