Abstract

The invention discloses a novel LED (light emitting diode) projection lamp which comprises a rear lamp housing, wherein an opening is formed in the front end of the rear lamp housing; the front end of the rear lamp housing is provided with a front lamp cover in a butting manner, and a lamp cavity is formed in the front lamp cover; a luminous assembly and a reflection cover for reflecting light are arranged in the lamp cavity; the novel LED projection lamp is characterized in that a rainwater temperature control probe for detecting whether raining occurs outside is arranged on the outer wall of the rear lamp housing; an air cooling device is arranged in the lamp cavity outside the reflection cover and comprises an air inlet pipe and an air exhaust pipe which are oppositely arranged on two inner sides of the rear lamp housing and are communicated with the outside; an air suction fan which is connected with the air inlet pipe and is used for blowing external air into the lamp cavity and an air exhaust fan which is connected with the air exhaust pipe and is used for exhausting hot air in the lamp cavity are respectively arranged at the bottom of the rear lamp housing; electromagnetic valves for controlling the air inlet pipe and the air exhaust pipe to be switched on and switched off are arranged in the air inlet pipe and the air exhaust pipe. Due to the arrangement, the novel LED projection lamp is high in heat dissipation performance and waterproofing performance.

Description

【Technical field】 [0001] The invention belongs to the technical field of lighting, and in particular relates to a novel LED floodlight with high heat dissipation. 【Background technique】 [0002] With the continuous development of the LED industry, LED energy-saving lighting technology has also been continuously improved. High-power LED floodlights have more and more application fields, and the heat dissipation and waterproof requirements of high-power LED floodlights are also being paid more and more attention. . However, the current high-power LED floodlights generally have problems such as unsatisfactory heat dissipation, bulky appearance, difficult maintenance caused by non-modular design, and inability to expand power. In order to meet the needs of the market, people urgently need to develop a new generation of LED high-power floodlights from the aspects of appearance, cost, heat dissipation, installation, and modular design. The heat sink of the traditional high-power...
