Problems solved by technology

At present, there is also an LED street lamp with a U-shaped cross-section substrate 2, but its irradiation range is affected by the inclination angle of the side wall of the substrate: when the inclination angle of the side wall is large, its lighting effect is different from that of an LED street lamp with a flat substrate Not much; when the inclination angle of the side wall is small, the phenomenon of uneven illumination and alternating light and dark will appear, as shown in Figure 3, and even blind areas will appear under the lamp, as shown in Figure 4

Embodiment 1

[0025] As shown in Fig. 5 and Fig. 6, the present invention includes a substrate 2 provided with several LEDs 1, the substrate 2 includes a planar portion 6 and two opposite slopes on both sides of the planar portion 6, several of the The LED1 is arranged on the planar portion 6 and each of the slopes, the slopes include two first-level slopes 11,12, two second-level slopes 21,22, and the two first-level slopes 11,12 The included angle between them is α, the included angle between the two second-level slopes 21, 22 is β, α=130°, β=86°, the divergence of the LED1 located on the planar portion 6 The angle is 60°, the divergence angle of the LED1 located on the first-level inclined surfaces 11, 12 is 60°, and the divergence angle of the LED1 located on the second-level inclined surfaces 21, 22 is 45°. In the test, this embodiment is installed at a height of 6 meters from the road surface. Under the condition of an elevation angle of 15°, the average illuminance and illuminance un...

Embodiment 2

[0027] As shown in Fig. 7 and Fig. 8, the difference between the present embodiment and the first embodiment is that the slope also includes two third-level slopes 31, 32, and the sandwich between the two third-level slopes 31, 32 The angle is γ, α=120°, β=84°, γ=60°, the divergence angle of the LED1 located on the planar portion 6 is 60°, and all LEDs located on the first-level inclined surfaces 11, 12 The divergence angle of the LED1 is 60°, the divergence angle of the LED1 on the second-level slope 21, 22 is 45°, and the divergence angle of the LED1 on the third-level slope 31, 32 is 30°. After testing, this embodiment is installed at a height of 7 meters from the road surface. In the case of an elevation angle of 15°, the average illuminance and illuminance uniformity of the irradiation range can meet the national standards, and the irradiation range is wide. After testing, the best ranges of α, β and γ are: 100°≤α≤135°, 80°≤β≤110°, 50°≤γ≤80°.

[0028] The remaining featu...

Embodiment 3

[0030] As shown in Fig. 9, the difference between this embodiment and the second embodiment is that the substrate 2 also includes three lighting distribution planes 10, 20, 30, and the three lighting distribution planes 10, 20, 30 are located on the substrate The ends of 2 are connected sequentially, and the LED1 is also provided on the three lighting distribution planes 10, 20, 30, so that the light intensity distribution in the irradiation range can be made more uniform, and the illuminance uniformity can be greatly improved. , the lighting effect is better.

[0031] The other features of this embodiment are the same as those of Embodiment 2.

[0032] The invention has wide irradiation range, uniform illumination, strong sense of transition, no bright and dark spots on the road surface, low power consumption, high brightness and small size, and is an ideal substitute product for existing street lamps.

Abstract

The invention discloses a LED street lamp, which aims at providing the LED street lamp which has the wide illumination range, the even illumination, the strong transition sense, the strong brightness, and the high power. The invention comprises a base plate (2) of a plurality of LEDs (1), the base plate (2) comprises a plane section (6) and oblique planes with at least two stages respectively opposite positioned on the both sides of the plane section (6), the LEDs (1) are arranged on the plane section (6) and the oblique planes, the oblique planes comprise two first oblique planes (11,12) and two second oblique planes (21,22), the included angle between the first oblique planes (11,12) is Alpha, and the included angle between the second oblique planes (21,22) is Beta, Alpha is more than 100 degrees and less than 135 degrees, and Beta is more than 80 degrees and less than 110 degrees. The invention can be widely applied to the outdoor lighting field.

Description

technical field [0001] The invention relates to a high-brightness and high-power 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 t...
