AI Technical Summary

Problems solved by technology

This leads to such a laser line projector occupying a large space and a high cost of materials.
[0006] In this regard, the existing technology has proposed a 360-degree laser line projector with a small footprint and low cost, but the laser line projector still has some defects, that is, stray light will appear in the part with a large angle

Embodiment Construction

[0026] The advantages of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0027] First, see figure 1 , Is a schematic diagram of a window module provided by a preferred embodiment of the present invention. The window module includes a front window, a left window and a right window perpendicular to the same plane. In order to facilitate the description of the positional relationship of the three windows, the projection of the three windows in the same plane is used to describe.

[0028] Such as figure 1 As shown, the projection of the front window in the plane is the line segment AB, the projection of the left window in the plane is the line segment BC, and the projection of the right window in the plane is the line segment AD. These three line segments form an isosceles trapezoid ABCD, Line segment AB is the upper base of the isosceles trapezoid ABCD, line segment BC and line segment AD are waists, and line segment ...

Abstract

The present invention provides a window module, which includes a front window, a left window and a right window perpendicular to the same plane, and the projections of the front window, left window and right window in the plane form an isosceles trapezoid, the window module The stray light can be eliminated on the basis of the prior art, so that the brightness of the horizontal laser line projected by the laser line projector can be balanced.

Description

Technical field [0001] The first aspect of the present invention relates to a window module. [0002] The second aspect of the present invention relates to a window having the window module. [0003] The third aspect of the present invention relates to a laser line meter with the window. Background technique [0004] With the continuous development of laser line casting instruments and the continuous expansion of its application range, customers have higher and higher requirements for laser line casting. [0005] For example, more and more customers require the laser line meter to project a 360-degree laser line, that is, the laser line can achieve full-angle coverage in a single plane. However, in the previous traditional laser line projectors, to achieve a 360-degree laser line, it is usually necessary to set a laser module at an interval of 90 degrees in a plane. The laser line projected by each laser module has a spread angle of approximately Between 120 degrees and 150 degrees,...
