Embodiment 1

[0023] Such as figure 1 As shown, the LED street lamp of this embodiment includes a light pole and a lamp body 101, wherein the light pole includes a main pole 103 and a pole 102, and the main pole 103 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 102 is used to make the lamp body 101 protrude above the road surface for illumination of the road surface.

[0024] The lamp body 101 includes a lamp holder and a PCB board; the lamp holder is used to fix the PCB board, and the LED light-emitting diode and other electronic components are installed on the PCB board, and the LED light-emitting diode is used for the LED of this embodiment Lighting of street lamps; 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, etc.

[0025] The lamp holder can be set as a plane plate, or a cu...

Embodiment 2

[0046] On the basis of each example in Embodiment 1, a plurality of positive power lines 204 and a plurality of negative power lines 206 may also be arranged on the PCB 201 .

[0047] 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 inside; other electronic components can be control modules, or resistors installed to prevent excessive current.

[0048] 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...

Embodiment 3

[0052] Such as image 3 As shown, in the above examples, when only the first group of LED light-emitting diodes 202 and the second group of LED light-emitting diodes 203 are provided in this embodiment, the overheating protection switch can be set with dual power supplies, that is, a pair of The power supply overheating protection switch is to replace the switch 1 and switch 2 in the first embodiment with a double power switch. The dual power switch is connected in series between the control module and the first group of LED light emitting diodes 202 , and between the control module and the second group of LED light emitting diodes 203 .

[0053] The light control sensor senses the intensity of external light, or the infrared sensor senses the signal sent by the remote control, or the electric control sensor senses the change of the current, or the voice control sensor senses the change of the sound, or the network sensor senses the command sent by the network , and notify th...

Abstract

The invention discloses an LED street lamp, which comprises a lamp post, a lamp body, a control device and at least one overheat protective switch, wherein the overheat protective switch is serially connected between the control device and various groups of LED light-emitting diodes; the lamp body comprises at least two groups of LED light-emitting diodes; the control device comprises an inductor, a control unit, a control switch and a control module; the inductor is connected with the control unit and is used for inducing the change and informing the control unit; the control unit, the control switch and a control module are sequentially and electrically connected, the control unit is used for starting the control switch to send a preset LED control signal to the control module when preset conditions are satisfied; the control module is connected with the various groups of the LED light-emitting diodes and is used for driving and controlling the LED light-emitting diodes according to the LED control signal; and the control device controls the state transformation of the overheat protective switch through the control unit. The LED street lamp has a simple structure and long service life.

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 LED street lamp, the body of the LED street lamp is only provided with one group of LED light-emitting diodes. When the LED street lamp is working, the group of LED light-emitting diodes is lit at the same time. For street lamps, the temperature inside LED street lamps is also relatively high, which affects the service life of each LED light-emitting diode, and the LED light-emitting diodes are also easy to burn out. [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...
