Abstract

The invention discloses a high-power LED light fitting, which has excellent heat radiating effect, wide irradiation range, even faculae and smooth transition. The high-power LED light fitting comprises a metal shell (1), an LED light source assembly (2), a transparent protection cover (3) and a reflecting cover (4), wherein the front side of the shell (1) is provided with a light source accommodating cavity (13), the LED light source assembly (2) and the reflecting cover (4) are arranged in the light source accommodating cavity (13), the back side of the shell (1) is provided with a plurality of heat radiating sticks (11) arranged in arrays, the LED light source assembly (2) comprises a plurality of high-power LEDs (21) and a circuit radiating bottom plate (22), a horizontal plane (100) and at least one level inclined planes symmetrically distributed along two sides of the horizontal plane (100) are arranged in the light source accommodating cavity (13), and the circuit radiating bottom plate (22) is contacted and is fixedly connected with the inclined planes and transmits the heat generated by the high-power LEDs (21) to the shell, so that the heat is radiated by the heat radiating sticks (11). The high-power LED light fitting can be widely applied in the field of LED light fittings.

Description

technical field [0001] The invention relates to a high-power LED lamp. Background technique [0002] As a new type of lighting source, LED is being more and more widely used in various occasions due to its outstanding advantages such as energy saving, environmental protection, high luminous efficiency, and long life. The application of high-power LED light sources in lamps can now be used as large lamps such as street lamps and wall washers. However, high-power LEDs generate a lot of heat when they are working. If they are not dissipated in time, the LEDs will be damaged due to high temperature and affect the service life. Therefore, good heat dissipation is required. Such as figure 1 As shown, the existing large-scale lamps generally use heat sinks to dissipate heat, but because the gaps between the heat sinks are arranged in parallel, if the wind blows from a direction perpendicular to the heat sinks, the air in the gaps between the heat sinks will not circulate. Smooth...
