Long-distance laser early warning lamp

Abstract

The invention discloses a long-distance laser early warning lamp of the technical field of optical warning. The lamp comprises a heat dissipation outer shell, a power supply waterproof connector is arranged on the outer wall of the right side of the heat dissipation outer shell, and a waterproof tail cover is connected to the outer wall of the power supply waterproof connector in a threaded mode. A laser unit driving control circuit is arranged on the left side of the waterproof tail cover, a laser unit module is arranged in an inner cavity of the heat dissipation outer shell, and an inner cavity of the laser unit module is provided with a first collimating lens, a second collimating lens and a third collimating lens from left to right. A focusing ring is arranged on the left side of the laser unit module and internally provided with a waterproof lens. Through the long-distance laser early warning lamp, lamplight warning with the range being larger than 2000 meters can be achieved, the lamp can be widely applied to the occasions needing long-distance warning and is particularly suitable for nighttime warning of freeway traffic police vehicles and wreckers and early warning of dangerous road sections, the occurrence rate of secondary accidents can be effectively decreased, and personal and property safety is ensured.

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
