Embodiment 1

[0034] Such as figure 1 , figure 2 As shown, a solar LED street lamp in this embodiment includes a main pole 101, a light pole 102, a lamp body 104 fixed on the light pole 102, a solar device, a control device and at least one overheating protection switch; The solar device includes a solar panel 105, a storage battery, and an electric control switch; the lamp body 104 includes a lamp holder 203, at least one PCB board 202, and at least one group of LED light-emitting diodes and their components arranged on the PCB board 202. Control module; the lamp body 104 is arranged directly below the solar panel 105; the battery is electrically connected to each group of LED light-emitting diodes after passing through the electric control switch and the control module in order to provide voltage to drive each group LED light-emitting diode; the control device includes a sensor, a control unit, a control switch and a control module; the sensor is connected to the control unit for sensin...

Embodiment 2

[0046] On the basis of Embodiment 1, a plurality of positive power lines 301 and a plurality of negative power lines 303 may also be arranged on the PCB 202 .

[0047] 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 201, so as to ensure that the interior of the LED street lamp The normal operation of each LED light-emitting diode and other electronic components; other electronic components may be the control module 304, 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 operati...

Embodiment 3

[0051] On the basis of Embodiment 1 or 2, in a solar LED street lamp, more than two groups of LED light-emitting diodes can also be set, and each group of LED light-emitting diodes is electrically connected to the battery through a pair of power supply positive and negative wires, that is Each group of LED light-emitting diodes has an independent power supply circuit. Moreover, each pair of positive and negative pole lines of the power supply is electrically connected to the same storage battery, and is powered by the same storage battery.

[0052] In addition, multiple storage batteries can also be fixed on the solar panel 105, and each storage battery is electrically connected to a pair of positive and negative wires of the power supply, so that each group of LED light-emitting diodes has an independent power supply circuit and power supply source.

[0053] And, each group of LED light-emitting diodes includes at least 1 red LED light-emitting diode, at least 1 green LED lig...

Abstract

The invention discloses a solar LED street lamp which comprises a lamp post, a lamp body fixed on the lamp post, a solar device, a control device, and at least one overheating protection switch, wherein the solar device comprises a solar panel, an accumulator and an electric control switch; the solar panel is provided with at least one fixing device; the lamp body comprises at least one group of LEDs (light emitting diodes) and control modules of the LEDs; the lamp body is arranged right below the solar panel and is fixedly connected with the solar panel through the fixing device; after passing through the electric control switch and the control modules sequentially, the accumulator is electrically connected with all groups of LEDs for providing voltage so as to drive all groups of LEDs. The solar LED street lamp has the advantages of simple structure, and firmer installation of the solar device and the lamp body.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to an LED solar 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. Solar street light is a kind of street light that uses solar energy as energy. Because it is not affected by power supply, it does not need to dig trenches and embed wires, it does not consume conventional electric energy, and it can be installed on the spot as long as there is sufficient sunlight. Therefore, it has attracted widespread attention. Because it does not pollute the environment, it is called a green environmental protection product. In the prior art solar street lamps, the solar device and the LED street lamp body are independently installed. Since the solar street lamp is installed outdoors, it is easily ...
