Embodiment 1

[0024] Such as figure 1 As shown, the LED street lamp of this embodiment includes a lamp post and a lamp body 101, wherein the lamp post is used to support the entire LED street lamp, so that the LED street lamp can be fixed on a specific place, and the lamp body 101 is fixed on the On the light pole, the pole 102 can enable the lamp body 101 to protrude above the road surface of the carriageway for road surface illumination of the carriageway.

[0025] The lamp body 101 is provided with a lamp holder and a PCB board; the lamp holder is used to fix the PCB board, and LED light-emitting diodes and other electronic components are installed on the PCB board, and the LED light-emitting diodes are mainly used for traffic lane Road lighting; other electronic components include resistors used to prevent excessive current of each LED light-emitting diode, control modules used to control LED light-emitting diodes, and so on.

[0026] The lamp holder can be set as a plane plate, or a c...

Embodiment 2

[0044]On the basis of each example in Embodiment 1, a plurality of positive power lines 202 and a plurality of negative power lines 203 may also be arranged on the PCB 201 .

[0045] Each power line can be set to include multiple positive power lines and multiple negative power lines. Each positive power line and each negative power line are respectively connected to an external power supply to provide voltage for each group of LED light-emitting diodes to ensure that the LED street light The normal operation of each group of LED light-emitting diodes and other electronic components; other electronic components can be control modules, or resistors installed to prevent excessive current.

[0046] Multiple pairs of positive and negative power lines can be connected to LED light-emitting diodes and other electronic components respectively. When a certain pair of positive and negative power lines is disconnected, it will not affect the normal operation of other positive and negativ...

Embodiment 3

[0051] In the above-mentioned embodiments, the rigid support body 105 can be set as a hollow tubular support body, and the end of the tubular support body can be provided with end caps to prevent water vapor, fallen leaves, dust, etc. from falling into it. Setting the support body in a tubular shape can reduce the material of the support body, reduce the weight, and facilitate transportation under the same function of support, and because there is a cavity in the tubular support body, each connecting line can be placed in the inner cavity, and the LED street light The overall beauty.

[0052] A plurality of small holes are provided on the tubular support body 105, each LED light emitting diode is arranged on the outer surface of the support body 105, each LED light emitting diode passes through each small hole, and is fixed on the inner surface of the tubular support body.

[0053] Generally, a small hole can be provided corresponding to each LED light-emitting diode, and a sm...

Abstract

The invention discloses an LED street lamp, which comprises a lamp post and a lamp body, wherein the lamp post comprises a rigid supporting body, and the rigid supporting body is provided with at least one group of LED light-emitting diodes; a light conduction layer is arranged outside the rigid supporting body and is used for evenly leading light rays out; and the lamp body is fixed on the lamp post through a supporting rod and is in electrical connection and signal connection with the lamp post. The lamp post of the LED street lamp can give out light and can synchronously illuminate road surfaces of lanes and sidewalks.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to an LED street lamp. Background technique [0002] Because LED street lamps have the characteristics of long life, high light source, no radiation, and low power consumption, LED semiconductor light sources have been widely used in the lighting field in recent years. In the LED street lamp of the prior art, the LED street lamp lamp body is fixed on the light pole, and is protruded through the pole and placed above the road surface. Since the lamp body generally only illuminates the driveway, compared with the sidewalk, the brightness of the light is difficult to meet the demand. [0003] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an LED street lamp which can emit light on a lamppost and can illuminate both the driving lane and the sidewalk. [0005]...
