Application of solar corridor lights

Solar corridor lights belong to the new architectural lighting system. The single light of the solar corridor light adopts sound and light control, which can turn on the light when people come and turn off the light when people leave, saving energy, reducing consumption and being convenient to use. The solar power system is simple and easy to use, and there is no fear of power outages. The solar corridor light uses a long-life digital light source and a low-voltage independent power supply system, with safe and reliable functions, one-time investment, and long-term free use, which can meet the different needs of residential buildings and office buildings. Promoted to the level of building construction. 1. Working principle The solar corridor light includes a solar cell installed on the roof of the building and lighting installed on each floor, as well as a battery and a charge and discharge controller that are placed in a consistent manner. The battery is connected with the lights on each floor through wires. The load uses LED lamps, and cooperates with sound and light control switches. During the day, the solar cell module generates electrical energy under the irradiation of a certain intensity of sunlight, and is stored in the battery through the solar charge and discharge controller; at night, the battery supplies electrical energy to the load through the charge and discharge controller. Generally, the solar system will increase the capacity of the battery according to the actual situation to ensure the lighting in rainy days. 2. System performance indicators (1) Lighting power scale: 2-5W; (2) Power supply type: DC; (3) Solar cell conversion power: >15.5%; (4) System electrical power: >85%; (5) ) Solar cell open circuit voltage: (6) Maximum operating current of solar cell: <1.8A; (7) Battery equipment voltage: DC12V8, battery undervoltage protection point: 11.6V±1%; (8) Battery undervoltage protection point: 11.6 V±1%; (9) Battery overcharge protection point: 14.4V±1%; (10) Battery overcharge recovery point: 13.8V±1%; (11) Reverse connection protection for batteries and solar cells; (12) With load short circuit and overload protection; (13) Control method: battery overcharge and over discharge control, single lamp fire control voice control; (14) System lamps, LED lamps (DC). To sum up, the advantages of solar road corridor lights can be drawn: (1) Energy saving: solar energy photoelectric conversion is used to supply electric energy, which is inexhaustible and inexhaustible; (2) Environmental protection: no pollution, no noise, no radiation; (3) ) Safety: Low-voltage DC power supply, no accidents such as electric shock, fire, etc.; (4) Convenience: The installation is simple, the operation is convenient, and there is no fear of power outages and power cuts; (5) Long life: solar panels are more than 20 years old, The battery lasts for 3-5 years, and the LED light source can reach more than 50,000 hours; (6) High level: high-tech commodities, green power, the operating unit pays attention to technology, green image progress, and level promotion; (7) Economy: one investment, long time (8) Wide application: solar power comes from nature, so it can be used wherever there is sunshine. For example, the lighting of corridor lights is attributed to public facilities. In principle, the management of installation protection is shared by the owner and the property. At present, the fee for corridor lights includes two parts, one of which is the protection fee, and the other is the electricity fee. However, in practice, the charges for corridor lights are not the same and there is no consistent standard, which makes the owner and the property management department confront sharply. There are still many corridor lights that still use light bulbs and old switches to stay on all night. If the corridor lights are changed to LED lighting, sound and light switches are used. This kind of solid-state lighting with light-emitting diode LED as the light source consumes only 1/8 of the general incandescent lamp, but its lifespan is 10 times longer. For example, the 25W incandescent lamps originally used in the corridor of the community will be changed to 3W LED lamps, and each lamp can save 8 times the power consumption, that is, each corridor lamp needs only 1.68 kWh of electricity per year (original demand is 18.25 kWh), 300 lamps Corridor lights only require 504 kWh of electricity, which can save 4971 kWh of electricity every year. The use of solar corridor lights can not only save energy and reduce consumption, but also make one-time investment free for a long time, which alleviates the conflict between the property management department and the owner and reduces the property management cost, and the overall cost is more cost-effective. Therefore, from the point of view of shopping malls, not only can the existing corridor lighting system be retrofitted to save energy, but also a solar power system can be installed according to user needs, which has a broad prospect and is suitable for implementation. Such energy-saving and user-friendly products will surely show great success in the lighting industry.
