Information

1、 Professional terminology knowledge of lighting fixtures

Wavelength: The change in color intensity of light can be described through data, which is called wavelength. The wavelength of the light we can see ranges from 380 to 780nm, in nanometers (nm).

Brightness: Brightness refers to the degree of brightness of an object, defined as the luminous intensity per unit area, measured in nits.

Light intensity: refers to the brightness of a light source, which represents the physical quantity of visible light radiation intensity emitted by the light source in a certain direction and range, in candlelight (cd).

Luminous flux: The total amount of visible light emitted by a light source per second, in lumens (Lm). Light efficiency: The luminous flux emitted by a light source divided by the power of the light source. It is an important indicator for measuring energy efficiency of a light source, measured in lumens per watt (Lm/w).

Color rendering: The degree to which a light source presents an object, that is, the degree of color realism, commonly known as the "color rendering index". Indoor color rendering is usually expressed as Ra, expressed numerically, and Ra100 is the color rendering under sunlight.

Color temperature: When the color of the light emitted by a light source is the same as the color of the light emitted by a blackbody at a certain temperature, the temperature of the blackbody is called the color temperature of the light source. Only white light has a color temperature, in Kelvin (k).

Glare: Visual discomfort caused by objects with extremely high brightness or strong contrast in the field of vision is called glare, which is an important factor affecting lighting quality.

Synchronicity: Two or more LED lights can operate normally according to the program setting within an unspecified time, generally referring to internal control LED lights. Synchronicity is the basic requirement for LED lights to achieve coordinated changes.

Protection level: IP protection level is a classification of lighting fixtures based on their dust and moisture resistance characteristics, consisting of two numbers. The first number represents the level of dust and moisture resistance of the lighting fixture (divided into 0-6 levels), and the second number represents the sealing degree of moisture and water resistance of the lighting fixture (divided into 0-8 levels). The larger the number, the higher the protection level.

Photoperiod: The natural or artificial cycle of light and dark that can affect biological organisms.

Photometric measurement: Based on the given luminous efficiency function, such as V( λ) And V '( λ), The method of measuring radiation levels.

Light intensity distribution: The distribution of light intensity in various directions of a light source or fixture in space.

Light intensity curve chart (table): The light intensity is given by polar coordinates or charts, and the values in the table represent the light intensity generated by the light source at every 1000 lumens of light flux. For the case of asymmetric distribution of light intensity, two different light intensity distribution maps in different planes can be used to represent the light intensity distribution of the lamp
