Description

TECHNICAL FIELD

[0001] The present application relates to a photovoltaic lighting device, in particular to a high-power long-endurance photovoltaic lighting device. BACKGROUND

[0002] The photovoltaic lighting has entered the stage of wide use, and is widely used in street lamps, squares and other places. It uses photovoltaic panels to generate electricity by receiving light, and stores the electricity in lithium batteries. When the external light is weak, the light source is lit by using the electricity stored in the lithium battery. The current photovoltaic panels are arranged at the top of the lamp pole, above the light source, and in a position that is not illuminated by the light source. The power of the photovoltaic panels is increased by being connected in series and / or parallel. The current widely used control method is that when the external light is strong, the photovoltaic panels generate electricity and charge the battery, and the light source does not work at this time. When the external light is weak, the photovoltaic panels do not generate electricity, and the control system controls the battery to supply power to the light source to light the light source. The purpose of arranging the current photovoltaic panels above the light source is also to avoid the situation that when the light is weak, the lighted light source will illuminate the photovoltaic panels, so that the photovoltaic panels generate electricity. When the photovoltaic panels generate electricity, the control will cut off the power supply of the light source, so that the light source is extinguished. After the light source is extinguished, the photovoltaic panels do not receive light, and the control program will light the light source again. Thus, the light source is in a cycle of lighting and extinguishing, and the light source flashes continuously.

[0003] On the other hand, the current photovoltaic panels are limited by the power generation power, and the electricity generated during the day can only provide small-power lighting. If a high-power photovoltaic street lamp is to be installed, the power of the photovoltaic panels needs to be increased, which will inevitably increase the area of the photovoltaic panels. Especially on the top of the high pole, the area of the installed photovoltaic panels is too large, and when the wind blows, the torque on the base part of the lamp pole will increase. In order to ensure the safety of the structure, the size of the lamp pole needs to be increased, which will significantly increase the cost.

[0004] Therefore, there is a problem that if the photovoltaic panels are arranged above the light source, the area of the photovoltaic panels needs to be increased when high-power long-endurance is required, which will increase the structural size of the lamp pole and increase the cost. If the photovoltaic panels are arranged below the light source, the light source will flash.

[0005] Therefore, the current photovoltaic lighting, especially the photovoltaic lighting on the high pole, has small power and short endurance time due to the consideration of cost and control method. SUMMARY

[0006] In order to solve the technical problems of small power and short endurance time of the photovoltaic lighting mentioned in the background art, the present application provides a high-power long-endurance photovoltaic lighting device, which can arrange the photovoltaic panels below the light source without changing the current control method, thereby avoiding increasing the structural size of the lamp pole and reducing the cost.

[0007] A high-power long-endurance photovoltaic lighting device, comprising a lamp, a battery, a controller and a photovoltaic panel power source electrically connected to each other, the photovoltaic panel power source comprises a plurality of photovoltaic panel layers in spatial arrangement, the photovoltaic panel layers comprise a plurality of parallel arranged photovoltaic panels, wherein one or two photovoltaic panels on one photovoltaic panel layer are connected in series with one or two photovoltaic panels on another photovoltaic panel layer to form a photovoltaic panel power source group, and the photovoltaic panel power source groups are connected in series or parallel to form the photovoltaic panel power source.

[0008] The arrangement of the photovoltaic panel layers and the photovoltaic panels enables the sunlight to fully irradiate each photovoltaic panel, while the light source emitted by the lamp cannot fully irradiate each photovoltaic panel.

[0009] The photovoltaic panel layers in the photovoltaic panel power source group are arranged in parallel in the up-down direction.

[0010] Preferably, the angle between the plane where the photovoltaic panel layers are located and the plane where the lamp is located is 30-60 degrees.

[0011] Preferably, the plane of the photovoltaic panel layers in the up-down direction forms an angle of 30-45 degrees with the horizontal bar of the lamp.

[0012] The photovoltaic panel power source is arranged below the lamp. BRIEF DESCRIPTION OF DRAWINGS

[0027] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] In the following embodiments, the photovoltaic panels connected in series in the photovoltaic power supply are arranged alternately in the vertical direction so that these photovoltaic panels connected in series cannot be illuminated by the lamps at the same time.

[0029] Example 1

[0030] A high-power, long-lasting photovoltaic lighting device, as shown in the figure, includes a lamp, a battery, and a photovoltaic power supply that are electrically connected to each other. The photovoltaic power supply is spatially arranged as multiple photovoltaic panel layers, each photovoltaic panel layer including multiple photovoltaic panels arranged in parallel. One photovoltaic panel on one of the photovoltaic panel layers is connected in series with one photovoltaic panel on another photovoltaic panel layer to form a photovoltaic power supply group. Multiple photovoltaic power supply groups are connected in series or in parallel to form a photovoltaic power supply.

[0031] More specifically, such as Figures 1-4 As shown, the light fixture 6 is mounted on the horizontal bar 52 of the upright pole 51. The upright pole 51 also has a first layer of photovoltaic panels 10, a second layer of photovoltaic panels 20, and a third layer of photovoltaic panels 30 installed on it, all arranged below the light fixture 6. Specifically, the first layer of photovoltaic panels 10 includes a first layer of first photovoltaic panels 11, a first layer of second photovoltaic panels 12, and a first layer of third photovoltaic panels 13 arranged side-by-side; the second layer of photovoltaic panels 20 includes a second layer of first photovoltaic panels 21, a second layer of second photovoltaic panels 22, and a second layer of third photovoltaic panels 23 arranged side-by-side; and the third layer of photovoltaic panels 30 includes a third layer of first photovoltaic panels 31, a third layer of second photovoltaic panels 32, and a third layer of third photovoltaic panels 33 arranged side-by-side. For example... Figure 5As shown, the electrical connection between them is that the first layer first photovoltaic panel 11, the second layer second photovoltaic panel 22, the third layer third photovoltaic panel 33 are connected in series to form U1, the first layer second photovoltaic panel 12, the second layer third photovoltaic panel 23, the third layer first photovoltaic panel 31 are connected in series to form U2, and the first layer third photovoltaic panel 13, the second layer first photovoltaic panel 21, the third layer second photovoltaic panel 32 are connected in series to form U3. U1, U2, U3 are connected in series or parallel to form a light source panel power supply, the photovoltaic panel power supply is connected with the controller, and the controller is used for charging the battery. The controller can also control the lighting of the lamp.

[0032] The first layer photovoltaic panel 10, the second layer photovoltaic panel 20 and the third layer photovoltaic panel 30 are installed at the middle position of the lamp pole instead of the top end of the lamp pole, so that the thicker feature below the lamp pole can be utilized to obtain a more stable structure. Meanwhile, in the case that the total area of the photovoltaic panel power supply is the same, the installation of the first layer photovoltaic panel 10, the second layer photovoltaic panel 20 and the third layer photovoltaic panel 30 at the middle position of the lamp pole can reduce the force arm of the wind blowing the photovoltaic panel to the lamp pole base, thereby reducing the torque of the wind to the lamp pole base, and a larger number and larger area of photovoltaic panels can be arranged without increasing the size of the lamp pole, so as to achieve the purpose of large power.

[0033] The photovoltaic panel layers are arranged in an up-down manner. When the lamp is lit, the lamp will irradiate the first layer photovoltaic panel 10, but cannot completely irradiate the second layer photovoltaic panel 20 and the third layer photovoltaic panel 30, therefore, as long as a part of one of the second layer second photovoltaic panel 22 and the third layer third photovoltaic panel 33 of U1 is not completely irradiated by the light emitted by the lamp, U1 as a whole will not generate electricity; similarly, as long as a part of one of the second layer third photovoltaic panel 23 and the third layer first photovoltaic panel 31 of U2 and the second layer first photovoltaic panel 21 and the third layer second photovoltaic panel 32 of U3 is not completely irradiated by the light, U2 and U3 will also not generate electricity. If the control program does not detect the generation of electricity by the photovoltaic panel, the lamp will be continuously lit.

[0034] As shown, the angle between the plane where the photovoltaic panel layer is located and the plane where the lamp is located is 30-60 degrees.

[0035] As shown, Figure 2 As shown, the angle between the plane where the photovoltaic panel layer is located and the plane where the lamp is located is 30-60 degrees.

[0036] The above is only the case of three groups of power supply composed of three layers of photovoltaic panels, in fact, other layers of photovoltaic panels can be set according to needs, and the power supply can be three groups, four groups, etc., as shown in Figures 7-9

[0037] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as limiting the utility model, and the ordinary skilled in the art can change, modify, replace and modify the above-mentioned embodiments within the scope of the utility model.​
