Description

Technical Field

[0001] The utility model relates to the technical field of lighting devices, in particular to a clamp-type photovoltaic induction lighting device. Background Art

[0002] Photovoltaic lighting devices generally use conventional bifacial PERK cells, and the efficiency of converting absorbed light into electricity is generally between 22% and 23%. The efficiency of the HJT cells used in this device is 24% to 25%, and its low-light effect is better (under 600W / ㎡ radiation intensity in the evening or on cloudy days), which is about 0.5% to 1% higher than that of conventional bifacial PERK cells. The attenuation rate of HJT cells is lower than that of conventional bifacial PERK cells, and the life cycle is longer. In addition, the temperature coefficient is lower, which produces a higher open-circuit voltage, ensuring higher output power and weather resistance durability.

Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0019] like Figure 1-2 As shown, a clamp-type photovoltaic induction lighting device includes a photovoltaic induction lighting unit, which is fixed to a roadside pole body by a fixing assembly. The pole body includes a roadside electric pole or tree. The fixing assembly includes a clamp 14 and a support rod 13. The clamp 14 is fixed to the aforementioned electric pole or tree by a sleeve connection. One end of the support rod 13 is fixed to the clamp 14, and the other end is fixed to the photovoltaic induction lighting unit. The photovoltaic induction lighting unit is fixed to the roadside pole body by the aforementioned fixing method.

[0020] As an improved implementation, an adjusting device for adjusting the angle of the photovoltaic induction lighting unit is provided between the support rod 13 and the photovoltaic induction lighting unit, and the illumination angle of the photovoltaic induction lighting unit is adjusted by the adjusting device, wherein the adjusting device may be a rotating shaft 12 or a universal joint.

[0021] The photovoltaic induction lighting unit includes a lighting unit, an energy storage unit and a control unit. The energy storage unit supplies energy to the lighting unit. The control unit is arranged on the energy supply path to adjust the on and off of the energy supply path. The aforementioned lighting unit, energy storage unit and control unit are all fixedly arranged in the housing 5, and the housing 5 is fixedly arranged on the aforementioned adjustment device. Figure 1 As shown, the energy storage unit includes a HJT battery cell 1 and a lithium battery 10. A plurality of HJT battery cells 1 are arranged and combined, and are coated with an EPE film 3 to form a HJT battery cell 1 unit. A busbar 6 is provided on the edge of the HJT battery cell 1 unit, and the HJT battery cell 1 is connected to the lithium battery 10 by the busbar 6, so that the lithium battery 10 is charged by the HJT battery cell 1. The aforementioned lighting unit includes an LED light strip 4, which is fixedly arranged based on the edge of the aforementioned housing 5, and is powered by the aforementioned lithium battery 10.

[0022] like Figure 2As shown, in order to protect the aforementioned HJT battery, the lighting unit, the energy storage unit and the control unit are fixed in the housing 5 by means of tempered glass 2, and the tempered glass 2 and the housing 5 are fixed by means of sealing silicone 7 and butyl silicone 8. Figure 3 The schematic diagram shows the local enlarged structure of area A, as shown in Figure 3 As shown, based on the outer side of the busbar 6, butyl silicone 8 and sealing silicone 7 are used in sequence from the inside to the outside to fix the tempered glass 2 and the outer shell 5, and the busbar 6 is fixed and sealed simultaneously.

[0023] The structure and application of the control unit are described below. The control unit includes a control circuit board 9 and a photo sensor 11. The control circuit board 9 is arranged on the path between the lithium battery 10 and the LED light strip 4. The signal output end of the photo sensor 11 is connected to the signal receiving end of the control circuit board 9. The external light intensity is detected by the photo sensor 11. When the light intensity is sufficient, the HJT cell 1 continuously generates electricity and supplies the electric energy to the lithium battery 10 through the busbar 6. The lithium battery 10 completes the storage of electric energy. At this time, no path is formed between the lithium battery 10 and the LED light strip 4; when the light intensity is insufficient, the photo sensor 11 sends a signal to the control circuit board 9, and the control circuit board 9 regulates the formation of a path between the lithium battery 10 and the LED light strip 4. The lithium battery 10 supplies energy to the LED light strip 4, thereby completing the lighting of the road. In this process, the control circuit board 9 actually acts as a switch of the path between the lithium battery 10 and the LED light strip 4, and the photo sensor 11 detects the external light intensity to determine the on-off condition of the path. It is worth noting that the aforementioned control circuit board 9 and the photo sensor 11 are both fixed between the HJT battery and the lithium battery 10, and the photo sensor 11 is fixedly disposed in the transparent gap between the HJT battery cell 1 and the housing 5, so that the photo sensor 11 can detect the external light intensity.

[0024] The clamp-type photovoltaic induction lighting device can be fixed on the column on the roadside by means of a clamp 14, without the need for additional modification of both sides of the road, and its angle can be adjusted by means of an adjustment device. The adjustment device has a certain damping and can adapt to columns of different angles on the roadside to ensure the angle consistency of the photovoltaic induction lighting devices set on both sides of the road. In addition, the HJT cell 1 is used inside the clamp-type photovoltaic induction lighting device to receive sunlight, and the converted electric energy is stored in the internal lithium battery 10. Then, a photo sensor 11 and a control circuit board 9 are used to automatically supply the electric energy in the lithium battery 10 to the LED light strip 4 to emit light when the external light is insufficient, thereby ensuring the lighting of the road. When the light is sufficient, the electric energy is converted and stored.
