Embodiment 1

[0025] As shown in Fig. 1, Fig. 2 and Fig. 3, the present invention includes a substrate 2 provided with several LEDs 1, and the substrate 2 includes three-stage slopes 21, 22, 23, and the slopes 21, 22, 23 are arranged gradually from outside to inside. The stages are inclined to the horizontal plane, and several LEDs 1 are arranged on the inclined surfaces 21, 22, 23. There are four inclined surfaces 21, 22, 23 in each stage, and the inclined surfaces 21, 22, 23 in the same stage form One level of quadrangular pyramid, the side of the quadrangular pyramid is provided with the LED1, each level of the quadrangular pyramid includes two long slopes 3 and two short slopes 4, the back of the substrate 2 is provided with a radiator 5. The substrate 2 is concave, and compared with the convex substrate, it is not easy to adhere to dust, easy to dissipate heat, and is more suitable for use with the existing street lamp housing.

[0026] Of course, the base plate 2 can be at least two l...

Embodiment 2

[0028] As shown in FIG. 4 , the difference between this embodiment and the first embodiment is that the substrate 2 is convex.

[0029] The remaining features of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0031] As shown in Figure 5, the difference between this embodiment and Embodiment 1 is that the substrate 2 is arranged in a metal lampshade 6, a part of the radiator 5 is in close contact with the back of the substrate 2, and the other part In close contact with the lampshade 6, the heat sink 5 includes a heat conduction backplane 52 and several heat conduction ribs 51, the heat dissipation backplane 52 is in close contact with the inner surface of the lampshade 6, and the shape of the two Compatible, the upper part of the heat conduction rib 51 is fixedly connected with the heat dissipation back plate 52, and the lower part of the heat conduction rib 51 is provided with a lower folded edge 53, and the lower folded edge 53 is respectively connected with the slope 21 of each level. , 22, 23 close contact connection.

[0032] The remaining features of this embodiment are the same as those of Embodiment 1.

Abstract

The invention discloses an LED street lamp, which aims at providing a high power wide-angle LED street lamp with large coverage area, high illuminating value and low cost. The invention comprises a base plate (2) provided with a plurality of LEDs (1), the base plate (2) comprises at least two stages of bevel surfaces (21, 22, 23), the bevel surfaces (21, 22, 23) are inclined towards the horizontal plane by stages, and the LEDs (1) are arranged on the bevel surfaces (21, 22, 23). The invention can be widely applied to the outdoor lighting field.

Description

technical field [0001] The invention relates to a high-power wide-angle LED street lamp. Background technique [0002] The energy consumption in the lighting field accounts for about 20% of the entire electric energy, while only 30% of the electric energy of ordinary lighting lamps is used to emit light, and the rest is converted into heat energy and emitted to the outside world. LED is regarded as a cold light source because it generates less heat during operation and has higher luminous efficiency. LED street lights are composed of substrates with LEDs, lenses, and heat dissipation systems. Compared with traditional incandescent and fluorescent lamps, their energy-saving efficiency can reach more than 90%. Since its birth, it has attracted more and more attention from all over the world due to its high efficiency, low consumption, energy saving, environmental protection, and long life. At present, the electricity used for street lighting in my country is close to 250 bil...
