[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example 1:

[0031] like Figures 1 to 8 The illustrated solar LED street light includes a lamp holder 100 for mounting a light source. The lamp holder 100 is a light source mounting frame for mounting on a light pole. A light source plate 1 is mounted on the light-emitting surface a of the lamp holder 100, and a solar panel 2 is mounted on the backlight surface b of the lamp holder 100. The lamp holder 100 allows the electrical wiring of the light pole to extend into it to connect to the light source plate 1 and provide an external power source (mains power or power supply equipment). The light-emitting surface a is the side structure of the lamp holder used to emit light and provide illumination, and the backlight surface b is the side structure of the lamp holder away from the light-emitting surface a. Typically, the light-emitting surface a faces or towards the ground or road to ensure that the light can cover the road area below, while the backlight surface b faces or towards the sky to ensure that the solar panel 2 is not blocked by the street light structure, thus preventing the loss of sunlight effect.

[0032] More specifically, the light source board 1 is equipped with several LED beads 11 facing outwards. The LED beads 11 are commonly used light-emitting diode devices that release energy and emit light through the recombination of electrons and holes. The lamp holder 100 has an energy storage module installed inside for storing electrical energy. The solar panel 2 has solar cells 21 installed on the side away from the light source board 1. The energy storage module is electrically connected to the solar panel 2, the LED beads 11 and the external power source respectively. During normal use, the solar cells 21 of the solar panel 2 are used to supplement electrical energy. Then, when the street light is turned on, the electrical energy is supplied to the LED beads 11 for lighting. In the event of an unexpected failure of the solar panel 2, the street light can also be used in an emergency by a backup external power source (mains power or power supply equipment), reducing the risk of street light failure due to unexpected faults and ensuring the safe use of road lighting.

[0033] More specifically, the lamp holder 100 is provided with a heat dissipation structure 3 around the light source plate 1, which is arranged around the circumference of the light source plate 1 to form a heat dissipation ring surrounding the light source plate 1. The heat dissipation structure 3 conducts the heat of the light source plate 1 out of itself and then cools by air exchange. The lamp holder 100 of the street lamp is generally installed at a high suspended position away from the ground, where the overcurrent wind speed is large, which can accelerate the efficiency of natural cooling and heat dissipation, thereby quickly reducing the temperature of the lamp holder 100 and the light source plate 1, achieving effective cooling. On this basis, the horizontal projection area of the solar panel 2 is larger than that of the light source plate 1. The horizontal projection area is the maximum outline area of the component in the fixed installation position in the horizontal plane. The larger the horizontal projection area, the larger the area that can cover and block the direct sunlight. Therefore, the solar panel 2 can help the light source plate 1 to block sunlight and reduce the overall temperature of the light source plate 1 during the day. The light source plate 1 is located within the horizontal projection range of the solar panel 2 below, which uses the positional relationship to use the solar panel 2 as a "sunshade" for the light source plate 1. The solar panel 2 can not only charge and store energy, but also block direct sunlight, reduce the impact of sunlight on the light source plate 1, and effectively improve the service life of the street lamp light source.

[0034] As another embodiment 101 of embodiment 1, the solar cell 21 is arranged on the solar panel 2 in a directional array structure. The directional array structure includes uniform spacing along the length direction L or width direction W of the solar panel 2. The directional arrangement structure can maximize the use of the expansion area of the solar panel 2, fully absorb solar energy to improve the converted electric energy, and avoid irregular placement resulting in local area not being laid out resulting in waste of illumination area.

[0035] As another embodiment 102 of embodiment 101, the solar cell 21 is arranged on the solar panel 2 in a directional array structure. The directional array structure includes uniform spacing along the length direction L and width direction W of the solar panel 2. The length direction L and width direction W are simultaneously directional array to form a cell array structure as shown in Figure 4 or Figure 5 The cell array structure tries to cover the expansion area of the solar panel 2 to achieve full absorption of solar energy to improve the converted electric energy and avoid irregular placement resulting in local area not being laid out resulting in waste of illumination area.

[0036] As another embodiment 103 of embodiment 1, the lamp holder 100 comprises a fastening structure 4 facilitating detachable connection on the lamp pole, the fastening structure 4 comprises a fixed shell 41 fixedly connected on the lamp holder 100 and a fastening shell 42 detachably mounted on the fixed shell 41, when mounted, the fixed shell 41 covers the connecting end of the lamp pole, and a locking member (screw, bolt, latch or buckle) is used to pass through the fastening shell 42 and lock on the fixed shell 41 to clamp the position of the lamp holder 100 on the lamp pole, on this basis, in order to avoid accidental failure or damage of the LED lamp beads 11, a second light source 12 (a down lamp, a spotlight or a spotlight can be used) for independent lighting is also mounted between the fastening structure 4 and the light source plate 1, the irradiation direction of the second light source 12 is the same as that of the LED lamp beads 11, the brightness of the second light source 12 is greater than that of a single LED lamp bead 11, and the brightness of the second light source 12 is preferably greater than one third of the total brightness of the whole LED lamp beads 11, the brightness standard refers to GB / T 5700-2023 "Lighting Measurement Methods" for indicating the brightness of a light source or object, the brightness of the second light source 12 can be used as a supplementary light source for auxiliary lighting, and when the LED lamp beads 11 are damaged, a certain limit of road area lighting function can also be maintained through the second light source 12, and when the LED lamp beads 11 are not damaged, the second light source 12 can also be opened to enhance the lighting effect and improve the use effect of the lamp holder 100.
