Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a flood-proof floodlight. Background Art

[0002] Floodlights are lamps with a higher illuminance on the designated illuminated surface than the surrounding environment. They are currently widely used in tunnels, bridges, facade buildings, monuments, skyscrapers, large-scale mines, building outlines, stadiums, parks and flower beds. When floodlights are used in outdoor scenes to project downward, they are usually adjusted to an inclined irradiation angle. When it rains, rain will fall on the back of the floodlight, and some rainwater will easily accumulate in the dead corners of the lamp housing. Long-term accumulation of water will easily accelerate the rust of the lamp housing, affecting the service life and overall aesthetics of the floodlight. Utility Model Content

[0034] See also Figures 1 to 4 The utility model provides a floodlight that prevents water accumulation, including: an installation lamp housing, one side of which is provided with an installation box for installing a control device, and the other side of the installation box is provided with an installation chamber; a partition ring plate arranged in the installation chamber, the partition ring plate divides the installation chamber into a lamp board installation chamber and a heat dissipation and drainage chamber, and the heat dissipation and drainage chamber is surrounded by a plurality of drainage holes that are arranged through the installation chamber; an LED lamp board arranged in the lamp board installation chamber; and a lampshade assembly carried by the installation lamp housing, the lampshade assembly being sealed and connected to the partition ring plate to isolate moisture from the outside of the partition ring plate.

[0035] Specifically, the lampshade assembly includes: a transparent cover plate overlapped on the separation ring plate, and a pressure ring fixed to the mounting lamp housing for pressing the transparent cover plate so that the transparent cover plate and the separation ring plate are sealed and connected. The transparent cover plate is made of a glass plate, for example. After the LED light board is installed, the transparent cover plate is placed in the pressure ring and fixed to the mounting lamp housing through the pressure ring. The transparent cover plate is pressed against the separation ring plate and forms a sealing connection, thereby protecting the LED light board.

At the same time, the heat generated by the LED light board during operation can be transferred to the heat dissipation drainage cavity through the installed lamp housing. The heat dissipation drainage cavity and the drainage holes can increase the heat dissipation area and facilitate air flow, thereby improving the heat dissipation efficiency, further meeting the needs of extending the service life of the floodlight.
