Use of thermal energy to stimulate the light source, such as incandescent lamps, tungsten halogen lamps, high-pressure mercury lamps, metal halide lamps, etc.
Luminance
The luminous intensity of a luminescent body per unit of projected area in a given direction is called luminance and is expressed as L, in
Unit candela. Per square meter. (Cd/㎡)
The luminosity of a luminous body in the θ direction is
L=Iθ/Scosθ
The brightness of an object surface is related to the intensity of the light source and also to the reflective ability of the object.
Color temperature
When the color of light emitted by a light source is the same as the color emitted by a black body heated to a certain temperature, it is called the color temperature of the light source, or color temperature for short.
Conversion relationship
1 lux = 1 lumen of luminous flux uniformly distributed in an area of 1 square meter illuminance
1 lumen = luminous intensity of 1 candela point light source, the luminous flux emitted in the unit stereo angle
1 lux = luminous intensity of 1 candela point light source in the radius of 1 meter on the sphere to produce the luminous intensity
Cold light source
Light sources that use chemical and electrical energy to excite, such as LEDs, ELs, CFLs, fiber optics, fluorescent lamps, etc.
Hot light source
Use of thermal energy to stimulate the light source, such as incandescent lamps, tungsten halogen lamps, high-pressure mercury lamps, metal halide lamps, etc.
