How much is the solar patio light?
The basic difference between traditional street lights and LED street lights is the source of the light source. LED street light is a high-efficiency solid-state light source formed based on a semiconductor PN junction that can emit light with weak electric energy. Under a certain forward bias voltage and injection current, the holes injected into the P area and the electrons injected into the N area are in After being diffused to the active area, photons are emitted through radiation recombination, which directly converts electrical energy into light energy. We can distinguish them from the names of the two.
The light source of the former comes from the energy transmitted by traditional wires. The latter comes from solar energy. Obviously, when the power supply or wire fails, the traditional street lights will be 'blind'.
LED street lights are not affected by this. LED street lights provide lighting by absorbing solar energy and converting it into the required light source through a built-in system. Now more and more traditional street lamps are replaced by led street lamps.
In addition, according to the use of functional differentiation, the lighting in the building includes general lighting, partition general lighting, local lighting and mixed lighting.
1. General lighting: Regardless of the needs of special components, the uniform lighting method is set to illuminate the entire venue, which is called general lighting. Generally, general lighting should be set up in the workplace.
It can make the entire site get relatively uniform lighting, suitable for places where there is no special requirement for light direction or where local lighting and mixed lighting are not suitable for installation, such as warehouses, some production vehicles, offices, conference rooms, classrooms, waiting rooms, etc. . Guest rooms, business halls, etc.
Division general lighting: According to needs, general lighting is designed to illuminate a specific area, such as the place where work is performed, and it is designed to be different lighting areas.
When the illumination requirements are different in different areas of the same place, general lighting should be used in different areas of the same place. In the work area with high contrast requirements, the lamps can be arranged in a concentrated and uniform manner to increase the illuminance value, while other areas still adopt the general lighting arrangement. Such as factory workshop market lines, conveyor belts, rod inspection points, etc.
3. Local lighting: For specific visual work needs, the lighting that illuminates a certain part is called local lighting. It focuses on the area where the visual effect is located and the nearby area.
Some work environments or activities have very high requirements for lighting level and lighting quality. General lighting methods alone cannot meet the lighting requirements either technically or economically. Therefore, auxiliary lighting devices need to be installed in these places. Replenish locations with insufficient lighting. It should be noted that local lighting should not be used only in the workplace.
Fourth is mixed lighting: the lighting method composed of general lighting and local lighting is called mixed lighting.
For some operating surfaces, the illuminance requirements are high, and general lighting alone is not suitable for this place. Mixed lighting should be used. On the basis of general lighting, local lighting is added, and sample selection is conducive to improving illuminance and saving electric energy.
Friendly reminder, when buying LED street lights, don't just pay attention to its energy-saving performance. You should consider your actual situation. Only products that meet your needs are truly good products.
