The invention relates to a high-power LED (Light-Emitting Diode) signal lamp. According to the technical scheme provided by the invention, the high-power LED signal lamp comprises a rear cover and a light distribution lampshade which covers the front end of the rear cover, wherein a heat-dissipation plate is arranged at the inside bottom of the rear cover; a mounting plate is arranged on the heat-dissipation plate; a plurality of high-power LEDs are adhered on the mounting plate; a light distribution lens covers each high-power LED on the mounting plate; a Fresnel lens is arranged at the inside bottom end of the light distribution lampshade; light emitting surfaces of the high-power LEDs are fixed on the focal plane of the Fresnel lens; and lights emitted by the high-power LEDs are focused into parallel lights by the Fresnel lens, and then light rays at required angles are emitted through the light distribution lampshade. The high-power LED signal lamp is compact in structure, capable of improving the light utilization rate of the high-power LEDs, high in lamp surface brightness, even in lamp surface light emission, good in water resistance and dust resistance, long in service life, low in use cost, safe and reliable.
Description
technical field [0001] The invention relates to a signal lamp, especially a high-power LED signal lamp, specifically a traffic signal lamp used for indicating various road traffic intersections, and belongs to the technical field of traffic signal lamps. Background technique [0002] At present, the mainstream signal lights on the market adopt the type of densely arranged bullet-shaped LED light-emitting diodes of φ5mm, such as image 3 shown. image 3 Among them, 30 represents densely arranged bullet-shaped LED light-emitting diodes, and 40 represents the light distribution lampshade of signal lamps; various patterns of indicator lights can be formed by bullet-shaped LED light-emitting diodes 30 . The light distribution type of the signal lamp with the above structure is simple, but cannot meet the optical design of the LED, and the utilization rate of the optical efficiency of the LED is low. With the development of high-power LEDs, the lumens of a single LED tube can be g...
