[0017] Depend on Figure 1-3 As shown, 1 in the figure is a square structure radiator, 5 is an LED, and 6 is a light source reflection bowl with an involute quadrangular truss structure. At the center of the upper part of the square structure radiator 1, a light pole is arranged in the axial direction. The mounting pipe frame 7 connected to the support arm, the square structure radiator and the heat dissipation frame 2 vertically arranged on the lower peripheral edge constitute the housing of the LED lamp, and the square structure radiator 1 lower plane in the housing is sequentially pasted A heat-conducting substrate 4 with an aluminum-based copper-clad laminate structure with evenly distributed LEDs, and a light source reflection bowl 6 with an involute quadrangular truss structure; the light source reflection bowl 6 is an involute structure composed of three inclined surfaces and a curved surface. A light source reflective bowl with a quadrangular truss structure, wherein t...

Abstract

The invention relates to an LED hard light device, comprising an LED and a radiator. The LED hard light device is technically characterized in that the upper part of the radiator is provided with a mounting pipe support arranged along the axial direction, and the radiator and a frame arranged at the periphery of the lower side of the radiator form a shell; a heat conduction substrate on which LEDs are evenly distributed and a light source reflecting bowl in an involute quadrangular prism structure are attached to the lower part of the radiator in the shell; the reflecting bowl consists of three inclined planes and a curved surface; an included angle between the axis vertical line of the reflecting bowl and a plane inclined in the direction of the axis of the heat conduction substrate is 56-61 degrees, and an included angle between the other two inclined planes adjacent to the inclined plane and the axis vertical line of the reflecting bowl is 20-25 degrees; an upper end bowl line of the curved surface, which is arranged opposite to the inclined plane, is arranged on the vertical parting line of the LEDs in the reflecting bowl; and the periphery of the lower part of the radiating frame is also provided with a trip strip for limiting a transparent lampshade. By adopting the structure, the evenly distributed LEDs and the reflecting bowl are matched to form cross and uniform irradiation, and two reflecting light sources are utilized, thereby the irradiation area is increased, and luminous spots are fundamentally eliminated.

Description

technical field [0001] The invention relates to the technical field of energy-saving lighting, in particular to an LED strong light device. Background technique [0002] As we all know, with the continuous development of semiconductor technology, LED semiconductor light source, as an energy-saving light source, has gradually been valued by government departments at all levels, and has a small amount of application in street lamp or spotlight lighting, and has become a lighting source after incandescent lamps and fluorescent lamps. The third-generation lighting source after lamps meets the needs of the high-tech transformation of "low carbon and environmental protection" advocated by the whole society. However, for the characteristic requirements of high-power LED light sources, the heat generated by LED light sources must be exported in time during work; due to the relatively small distribution of LED light sources, it is necessary to carry out secondary optical design and u...
