Description

Solar LED Street Light

technical field

The utility model relates to a solar LED street lamp.

Background technique

The working current of the LED street lamps used on the road is DC, and the working voltage is low, so the power supply must be converted into low-voltage, direct current to use, which not only increases the cost of the lighting system, but also reduces the utilization rate of energy. The power source of lighting is usually supplied by general power, which consumes a lot of energy and can only be used in the normal state of power supply. When the power supply fails, the lighting of street lights will be affected. At the same time, because the circuit pipelines are usually erected on electric poles or buried underground, it brings a lot of inconvenience to overhaul, maintenance and troubleshooting. Bulbs have a short lifespan and need to be replaced frequently.

Utility model content

The purpose of this utility model is to provide a kind of solar LED street lamp. The solar battery is arranged on the lamp frame, and the solar panel is used to absorb solar energy to generate electricity, which is provided for street lamp lighting, and has a long service life, low power consumption, and energy saving, which is beneficial Environmental friendly.

The purpose of this utility model is achieved as follows: a solar LED street lamp, including solar panels, LED light sources, control boxes, lamp holders and lamp holders, lamp holders are set above the lamp holders, solar panels are arranged on the lamp holders, and inside the lamp holders A plurality of LED light sources are arranged, a storage battery and a controller are arranged in the control box, the solar panel is connected with the controller and the storage battery in the control box through wires, and the output terminal of the controller is connected with the LED light source in the lamp holder.

The controller adopts a microprocessor with the functions of battery voltage detection, timing output, light control output and load output power adjustment as the core control circuit.

The solar battery panels are symmetrically arranged on the upper end of the lamp holder.

A plurality of LED light pipes are connected in series or in parallel in the lamp cap to form a plane or curved grid-shaped LED light source, and the LED light source is arranged on a reflector in the lamp cap.

The two ends of the arc-shaped lampshade of the LED light source of the lamp holder are provided with a secondary dimming cover, and the inner side of the secondary dimming cover is a mirror surface.

The lamp holder is composed of multiple hollow lamp poles which are movably connected.

The utility model has the following advantages:

1. The utility model utilizes solar panels to absorb solar energy to generate electricity, which is provided for street lamp lighting. It is safe, reliable, energy-saving, and has a long service life, which is beneficial to environmental protection.

2 LED light sources are small in size, low in heat generation, low in power consumption, long in life (more than 100,000 hours), and fast in response.

3 Solar cells directly convert light energy into DC power, and solar cell components can be combined in series or in parallel to obtain the actual required voltage. Combining solar cells with LEDs will eliminate the need for any intermediate inverters for AC, DC or high and low voltage conversion. This system will achieve high energy efficiency, high security and reliability.
