Long-distance laser early warning lamp

Abstract

The invention discloses a long-distance laser early warning light in the field of optical warning technology, which includes a heat dissipation housing. The outer wall on the right side of the heat dissipation housing is provided with a power supply waterproof joint, and the outer wall of the power supply waterproof joint is screwed with a waterproof tail cover. The left side of the waterproof tail cover is provided with a laser drive control circuit, the inner cavity of the heat dissipation shell is provided with a laser module, and the inner cavity of the laser module is respectively provided with a first collimator lens and a second collimator lens from left to right Straight lens and the third collimating lens, the left side of the laser module is provided with a focus ring, the focus ring is equipped with a waterproof lens, this product can achieve a light warning greater than 2000 meters, and can be widely used In the case of long-distance warning, it is especially suitable for night warning of highway traffic police cars and wrecker vehicles and early warning of dangerous road sections, which can effectively reduce the incidence of secondary accidents and ensure personal and property safety.

Description

technical field [0001] The invention relates to the technical field of optical warning, in particular to a long-distance laser warning light. Background technique [0002] At present, the early warning lights on the market all use traditional light sources or LED light sources to emit light, so that the warned person can see the light source to play a warning role, but this kind of product has the following defects such as the effective warning distance is too short: First, because the light source is Astigmatism, as the distance increases, the brightness of visible light will decrease sharply exponentially. Generally, the warning effect is relatively poor beyond 100 meters, and the warning effect is almost completely lost beyond 200 meters. Second, the warning lights are generally installed on police cars, and the height of the light source is limited, so it is easily blocked by vehicles such as trucks approaching, or because of road curves, undulations and other road condi...

Problems solved by technology

[0003] The object of the present invention is to provide a long-distance laser early warning light to solve the problem that the prior art early warning light proposed in the above background technology has a large divergence due to the concentration difference of the light source energy, so it can only have a warning effect for short distances. The problem of being powerless when there is a need for long-distance warning
