Basic knowledge of solar lighting:

When it comes to lighting up our spaces, solar lighting is becoming a popular choice. But what exactly is solar lighting, and why should you care? Let’s dive into the basics of solar lighting and explore how it can brighten your life—literally!

1. Illuminance (unit: lux, LX)

Measures the intensity of light irradiated on the surface of an object, that is, the luminous flux received per unit area, reflecting the degree to which light reaches a certain point.

(1lx) means that the area per square meter is illuminated by 1 lumen of luminous flux.

2. Luminous flux (unit: lumen, lm)

The maximum and minimum degree of light emitted by a light source is.

3. Luminous intensity (unit: candela, cd)

The amount of light emitted by a light source in a specific direction, reflecting the intensity of light

4. Brightness (unit: candela per square meter, cd/㎡)

The brightness of the surface of the luminous body or the irradiated object perceived by the human eye

5. Color temperature (unit: Kelvin, K)

An indicator that describes the color of the light source, and the value gradually increases from red to blue and white. In natural light, the color temperature of morning and evening glow is lower, and the color temperature of midday sunlight is higher.

6. Color rendering (Ra)

The ability of a light source to express its color when irradiating an object, the closer it is to natural light, the better the color rendering.

7. Luminous efficiency (unit: lumen per watt, Im/W)

The efficiency of a lamp in converting electrical energy into light energy, such as about 15lm/W for incandescent lamps and higher for fluorescent lamps
