On the charge of corridor lights

The corridor lighting charges are too chaotic. Their toll collectors don't have fixed time to charge, and we can't remember whether they paid this year, so we will pay the bill when they come to collect it.

Examples:

For example, the original 25W incandescent lamp used in residential corridors will be changed to 3WLE, and each lamp can save energy consumption by 8 times, that is, each corridor lamp only needs 1.68 kWh (originally 18.25 kWh) and 3 corridor lamps only need 54 kWh.

it can save 4971 kwh of electricity every year. The use of solar corridor lights can not only save energy and reduce consumption, but also be convenient to use, and the one-time investment is free for a long time, which alleviates the contradiction between the property management department and the owner and reduces the property management cost, and the comprehensive cost is more cost-effective.

Therefore, from the market point of view, not only can the existing corridor lighting system be energy-saving, but also a solar power supply system can be installed according to the user's requirements, which has a broad prospect and is suitable for popularization.

prospect:

corridor lighting is a public facility. In principle, the installation, maintenance and management are shared by the owner and the property. The corridor lighting fee includes two parts, one of which is the maintenance fee and the other is the electricity fee. However, in practice, the corridor lighting fee is different and there is no uniform standard, which makes the contradiction between the owner and the property management department sharp.

There are many corridor lights that still use bulbs and old-fashioned switches to stay on all night. If corridor lights are changed to LED lighting, acousto-optic switches are used. This kind of solid-state lighting lamp with LED as light source consumes only 1/8 of that of ordinary incandescent lamp, but its life span is 1 times.
