Description

An LED lighting system with wind-solar complementary centralized power supply

technical field

The utility model relates to a street lamp system for solar power supply and wind energy power supply for LED lighting, and discloses the design and structure of an environmental protection and energy-saving LED lighting street lamp system with wind and solar complementary centralized power supply.

Background technique

Wind-solar hybrid lighting technology has also been applied in China, but most of the domestic wind-solar hybrid lighting technology applications are still based on traditional thermal light source lighting, because of its low light efficiency, high heat consumption, short service life, and high application environment requirements. These reasons put a greater burden on the lighting system.

In addition, most of the existing wind-solar hybrid lighting technology principles in China are based on the combination of power generation equipment and lamps, that is, power generation equipment and batteries are directly installed on the lamps as components, which have high requirements for the placement of lamps. When the location is at a lower position or blocked by obstacles, it is difficult to access sunlight and natural wind, and the use of the lighting system is limited.

There are also street lamps in some construction areas in China that use a power supply system that separates the wind power generation system from the electrical equipment, but most of the power supply objects are short-term electrical equipment, and the distance between the power generation system and the point-of-use equipment is also limited. It is not suitable for street lighting systems that require long-term continuous lighting.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model aims to provide a device that can simultaneously utilize solar energy and wind energy to generate electricity and apply it to street lamps. The street lamp device can make all the energy required by the entire device come from the conversion of wind energy and light energy. There is no terrain and environmental restrictions, and there is no need for external supplementary power supply. The solar power generation equipment, wind power generation equipment, and power storage equipment are independent of the lighting equipment, and all lighting in a certain area is controlled by a master control circuit. The equipment is powered; it solves the problem that solar energy is not effective due to unstable light energy or the wind speed of wind energy is too small, and improves the energy conversion efficiency.

The technical solution adopted by the utility model to solve the technical problems is: a LED lighting street lamp system with wind and solar complementary centralized power supply, the system includes columns, lamp holder equipment, solar power generation system, wind power generation system, rectification equipment, power storage equipment, Shunt controller, output conversion power supply, LED lighting equipment, wherein the solar power generation system and wind power generation system are respectively connected to rectification equipment and power storage equipment, and the power storage equipment is connected to LED lighting equipment through the shunt controller and output conversion power supply; The rectification equipment includes a solar rectification controller, a wind energy rectification controller and an integrated circuit, and the solar rectification controller and the wind energy rectification controller are respectively connected to the integrated circuit; the LED lighting equipment is divided into a main light and an auxiliary light.

In the utility model, the electric energy required by the entire lighting system is jointly provided by the solar power generation system and the wind power generation system without external supplementary power supply. When the external light energy is sufficient but the wind power is insufficient, the wind power generation system can be omitted, and only the solar power generation system can provide lighting power; similarly, when the external wind energy is sufficient but the sunshine is insufficient, the solar power generation system can be omitted, and only the wind power generation system can provide lighting electricity. The electric energy converted from solar energy and wind energy is first stored in the power storage device, and then the power storage device supplies power to the LED lighting equipment.

As an optimized design of the aforementioned technical features: the LED lighting equipment includes one group, two groups and multiple groups, and each group of LED lighting equipment is provided with a group of independently driven and controlled output switching power supplies. LED lighting equipment refers to the sum of all LED lighting equipment in a certain area. The number of LED tunnel lighting equipment equipped with each output conversion power supply is determined by its output power. The function of the output conversion power supply is to convert the current output by the shunt controller into the current that can directly drive the LED lighting equipment; according to the specific application requirements, the corresponding LED lighting equipment group should also be set in the output conversion power supply to control the control equipment.

As a further optimized design of the aforementioned technical features: the power transmission distance between the shunt controller and the output conversion power supply is large and a transformer is installed. In the utility model, the shunt conversion between the regional centralized power storage and the individual power supply of each LED lighting equipment group is realized through the shunt controller, and the function of the shunt controller is to divide the current provided by the power storage device into multiple strands and send it to each output Converts the power supply and controls the electrical power delivered to each output converted power supply. When all LED lighting equipment in the entire lighting area can be integrated into one LED lighting equipment group, the shunt controller can be omitted, and the power transmission distance between the shunt controller and each output conversion power supply is large and the power transmission When the power is high, a transformer can be installed between the two, so that the transmission line between them is a high-voltage transmission line to reduce line loss.

As a further optimized design of the aforementioned technical solution: the main light of the aforementioned LED lighting equipment is a low-pressure sodium lamp, and the auxiliary light is a special energy-saving lamp.

The LED lighting street lighting system with wind and solar hybrid centralized power supply mainly supplies LED lighting equipment in a certain area, but it cannot be understood as limiting its power supply to other electrical equipment in or near the area. Solar energy and wind energy are converted into electric energy to supply power to lighting equipment without external power supply, and are suitable for various environments that are not conducive to external power supply; solar power generation equipment, wind energy power generation The equipment does not need to be placed in the sunshine and wind environment, so that the entire lighting system can adapt to various underground or mountain application environments; LED lighting equipment is used to improve light efficiency, reduce energy consumption, increase service life, and reduce system maintenance costs. And because the structure of the entire power generation system is simple and reliable, solar energy and wind energy form an organic complementarity, which has no impact on the environment, and the degree of dependence on the environment is smaller than that of a single power generation method, and the overall power generation capacity is increased by 60-80% compared with a single power generation method. It achieves the mutual complementation of wind energy and light energy, improves energy conversion efficiency, reduces costs, saves energy, and protects the environment.
