Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, the LED street lamp of this embodiment includes a light pole and a lamp body 1, wherein the light pole includes a main pole 3 and a pole 2, and the main pole 3 is used to support the entire LED street light, so that the LED street light can be fixed on a certain In a specific place, the pole 2 is used to make the lamp body 1 protrude above the road surface for road lighting,

[0028] The lamp body 1 includes a lamp holder 101 and a PCB board 102; wherein the lamp holder 101 is set as a plane plate, and the PCB board 102 is fixed on the lamp holder 101; the PCB board 102 can be fixed on the lamp holder 101 by a fixing unit, for example: using screws , rivets, welding units, pasting units and other conventional fixing methods.

[0029] Such as image 3 As shown, a positive power line 201 , a negative power line 203 , at least one signal line 202 , at least one LED light emitting diode 104 and a control module 204 are arranged on...

Embodiment 2

[0039] On the basis of Embodiment 1, a plurality of positive power lines 201 and a plurality of negative power lines 203 may also be arranged on the PCB 102 .

[0040] Each power supply line can be set to include multiple positive power supply lines and multiple negative power supply lines. Each positive power supply line and each negative power supply line are respectively connected to an external power supply to provide voltage for the LED light-emitting diode 104 to ensure that the LED The normal operation of each LED light-emitting diode and other electronic components in the street lamp; other electronic components may be the control module 204, or resistors installed to prevent excessive current.

[0041] 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 posi...

Embodiment 3

[0045] Such as Figure 4 As shown, in Embodiment 1, a concave portion 401 may also be provided on the lamp holder 101, and the PCB board 102 is fixed in the concave portion 401. The size and shape of the recess 401 is set according to the size and shape of the PCB board 102. For example, the recess 401 is set as a recess that only accommodates the space of the PCB board 102. The PCB board 102 can directly prevent the recess and be fastened in the recess 401.

[0046] For example, if the PCB board is strip-shaped, the recess can be a groove.

[0047] In addition, a fixing unit can also be provided to fix the PCB board 102 in the recess 401. For example, a pasting unit is provided, and the PCB board 102 is placed in the recess 401 and pasted in the recess by the pasting unit; , the PCB board 102 is provided with matching convex strips, and the PCB board 102 is fixed in the concave portion 401 through the matching concave portions and convex strips. In addition, a plug-in unit,...

Abstract

The invention discloses an LED street lamp, comprising a lamp post and a lamp body, wherein, the lamp body comprises a lamp holder and a PCB plate; the lamp holder is a plane plate, and the PCB plate is fixed on the lamp holder; the PCB plate is provided with a power cord, a signal wire, at least one group of LEDs and a control module thereof; the PCB plate and the surface of the lamp holder which faces to the LEDs are respectively provided with a film to reflect light. The street lamp has simple structure, wide illumination range and relatively centralized light.

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 prior art, generally LED street lamps are provided with a bowl-shaped concentrating cup for concentrated light emission. However, since street lamps are used outdoors and are used to illuminate a wide range of road surfaces, the beams are too concentrated, which will reduce the range of illumination. get smaller. [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 with simple structure, large illumination range and relatively concentrated light. [0005] The te...
