Description

Multi-point line laser lighting module

The creation department provides a multi-point line laser illuminating module, which can simultaneously represent the structure of the line and the multi-point, and is installed on the laser level and the instrument capable of emitting the laser light, so that the multi-point beam can be emitted on the line. The multi-point line beam provides an environment that can be clearly measured or marked by a multi-point line beam in an environment where the brightness is high and the general light cannot be clearly identified.

At present, the display of the reference line or the reference point for the laser light is formed as a separate device. When used, it is necessary to use two or more devices at the same time or in replacement, or to adjust the light to coincide display, because there are various processing. The process tends to accumulate more errors, and the accuracy of use is poor and inconvenient.

The main purpose of this creation is to use the combination of lens and cylindrical mirror with the configuration of total reflection lens and partial reflection lens, so that the laser light emitted by the laser diode is refracted by the lens and the cylindrical mirror, and then the total reflection lens and part After the reflection lens is reflected, the line beam and the multi-point beam on the line beam are synchronously generated, wherein the multi-point beam is evenly distributed on the line beam and simultaneously presented on the object; thus, the existing point line cannot be synchronously displayed and more than two units must be utilized. The device can achieve the effect and cause poor accuracy.
