Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

Referring to FIG. 1 , the solar street lamp described in the present invention includes a lamp post 9 , a solar photovoltaic panel 5 , an electrical storage device and a lighting fixture 1 . The bottom end of the light pole 9 is fixed with an installation base plate 10 for fixing the light pole on the ground or other attachments. An accommodating box is fixed on the top of the light pole 9, and the solar photovoltaic cell panel 5 is arranged obliquely and installed on the top of the accommodating box. The accommodating box body is divided into upper and lower layers, the upper layer is the controller box 6, and the lower layer is the battery box 7. The power storage device is a colloidal battery 3 , which is arranged in the battery box 7 . The controller box 6 is provided with an intelligent controller 4 for controlling charging and discharging of the colloidal battery 3 . The positive and negative poles of the colloidal battery 3 are electrically connected to the intelligent controller 4 respectively, and the solar photovoltaic panel 5 and the lighting fixture 1 are also electrically connected to the intelligent controller 4 respectively.

The lighting fixture includes a lamp base and an LED lighting lamp arranged in the lamp base. A horizontal lamp holder 2 is fixedly connected to the side wall of the upper end of the lamp post 9, and an arc-shaped support 8 is arranged below the lamp holder 2, and the bottom end of the support 8 is fixed on the side wall of the lamp post 9. One end is fixed on the lamp holder 2; the lamp head is fixed on the outer end of the lamp holder 2. The above-mentioned structural design makes the overall stability of the street lamp higher.

The shape specification of the solar photovoltaic battery panel 5 adopted by the utility model is: 620mm*420mm*30mm——805mm*535mm*35mm. This large-area solar photovoltaic panel can obtain a relatively large charging current, and can quickly charge the colloidal battery within a limited lighting time, thereby effectively ensuring the normal lighting of the lighting fixtures. According to the power of different solar street lamps, solar photovoltaic panels of different shapes and specifications are configured, and the corresponding wattages of solar photovoltaic panels of different shapes and specifications are also different.

The principle of the present utility model is as shown in Figure 2, the sunlight is irradiated on the solar photovoltaic battery panel, the solar photovoltaic battery panel 5 absorbs the solar light energy, and converts the light energy into electric energy, and charges the colloidal storage battery 3 through the intelligent controller 4; At night, the solar photovoltaic cell panel 5 senses the intensity of sunlight changes, and controls the discharge of the colloidal battery 3 through the intelligent controller 4, for the LED lighting lamp in the lighting fixture 1 to emit light.

The main functions of the intelligent controller 4 in the utility model include light control, time control, group control, photoelectric complementarity, overcharge and overdischarge protection, anti-reverse connection protection, anti-short circuit protection, temperature compensation, start-up delay and stable Constant current and other multi-level protection functions. Among them, the group control function is to more effectively use the limited electric energy stored in the colloidal battery. The specific performance is that the lighting time of LED lighting can be controlled intelligently and humanized. For example, 19 o'clock to 21 o'clock every day is the peak time period for people's night activities. During this time period, LED lighting should be illuminated at full power. After 21 o'clock, after the peak time of people's night activities, the LED lighting can be used for half-power lighting (that is, the brightness of the LED lighting is half of that of full-power lighting), which can reduce the consumption of electric energy. Under the condition that the brightness of the LED lighting lamp does not affect people's travel, the purpose of energy saving can be achieved.
