Description

An LED street lamp that can collect rainwater to generate electricity

technical field

The utility model relates to an LED street lamp capable of collecting rainwater to generate electricity.

Background technique

LED lamps are widely used because of their high electro-optical conversion efficiency and no pollution problems. At present, LEDs have been widely used in street lamps. When manufacturers design LED street lamps, their power supply systems are powered by the grid. , or adopt wind power generation and solar power generation, there is a lack of a power supply method that can collect rainwater and use the potential energy of rainwater to generate electricity.

Contents of the invention

The purpose of this utility model is to provide an energy-saving LED street lamp that can generate electricity by itself using rainwater in order to overcome the above-mentioned shortcomings of the prior art.

The problem to be solved by the utility model can be realized through the following technical solutions: an LED street lamp capable of collecting rainwater to generate electricity includes a hollow lamp post, an extension arm and an LED lamp head, and the extension arm protrudes from the hollow lamp post. The LED lamp head is installed at the end, there is a water storage funnel on the top of the hollow pole, and an impeller at the bottom, a generator next to the impeller, a small gear on the main shaft of the generator, and a large gear on the rotating shaft of the impeller. The small gear cooperates with the large gear, the generator is connected with the storage battery, and the storage battery is connected with the LED lamp head circuit.

After adopting the above structure, compared with the prior art, the beneficial effect of the utility model is: by turning the substrate upside down, its installation surface faces upwards, facing the reflector, and after installing the LED lamp on the installation surface, the LED lamp emits The light will be projected onto the reflector, and then the reflector will reflect the light to the ground. Due to the flip-up of the substrate, the substrate itself is used to block the glare, and the light projected by the LED lamp head is very soft.

Description of drawings:

Fig. 1 is a structural diagram of the utility model LED street lamp;

Fig. 2 is an enlarged structure diagram of part A in Fig. 1 .

Detailed ways:

The technology will be further described below in conjunction with the accompanying drawings.

The LED street lamp that can collect rainwater to generate electricity in this embodiment includes a hollow lamp pole 1, an extension arm 2 and an LED lamp holder 3,

The extension arm 2 protrudes from the hollow light pole 1, and an LED lamp holder 3 is installed at the end of the hollow light pole 1. A water storage funnel 4 is arranged on the top of the hollow light pole 1, and an impeller 5 is arranged at the bottom. A generator 6 is arranged beside the impeller 5 to generate electricity. The main shaft of the machine 6 is provided with a pinion 7, the rotating shaft of the impeller 5 is provided with a large gear 8, the small gear 7 cooperates with the large gear 8, the generator 6 is connected with the storage battery (not marked on the way), and the storage battery is connected with the LED Lamp holder 3 circuit connection.

When the water storage funnel 4 has stored rainwater, the rainwater is controlled to leak from the hollow light pole 1, and the impeller 5 is driven to rotate. While the large gear 8 rotates synchronously, the small gear 7 is driven to rotate, so that the generator 6 generates electricity, and the generated electric energy stored in the storage battery.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any person familiar with the technical field can easily think of All changes or replacements should fall within the protection scope of the present utility model.
