OUTDOOR LASER LIGHT

WIPO Patent Application WO/2016/119091

A1

Disclosed is an outdoor laser light, comprising a light housing (1) and a laser device, a circuit board (5) and a lower installation board (2) which are all provided inside the light housing (1). A cover (3) for covering the laser is on a top opening of the light housing (1); the periphery of the lower installation board (2) and an inner wall of the light housing (1) are in a sealed connection, and the laser device and the circuit board (5) are located in a chamber between the lower installation board (2) and the cover (3). Ventilation openings (11) are provided on the bottom of the light housing (1), and through holes (21) are provided in the lower installation board (2). Protruding rings (22) extending towards the bottom of the light housing (1) are provided on the periphery of the through holes (21). The ventilation between the exterior air and the interior part of the light housing is realized via the ventilation openings (11) and the through holes (21) so as to achieve a good ventilation and heat dissipation, and meanwhile the protruding rings (22) are able to effectively prevent water, that accidentally enters the light housing via the ventilation openings, from entering the space where the circuit board is in, thereby avoiding water reaching the circuit board inside the laser light.
