Artificial light at night refers to any light source other than a natural light source. Sources of artificial light include LEDS and fluorescents. This particular light source has effect on the reproduction, immune function, metabolism, thermoregulation and body temperature of organisms that need light for their daily activity.
1813 National Heat and Light Company formed by Frederick Albert Winsor. 1815 Humphry Davy invents the miner's safety lamp. 1823 Johann Wolfgang Döbereiner invents the Döbereiner's lamp. 1835 James Bowman Lindsay demonstrates a light bulb based electric lighting system to the citizens of Dundee.
A lighting control system is intelligent network-based lighting control that incorporates communication between various system inputs and outputs related to lighting control with the use of one or more central computing devices. Lighting control systems are widely used on both indoor and outdoor lighting of commercial, industrial, and ...

This is a list of sources of light, the visible part of the electromagnetic spectrum.Light sources produce photons from another energy source, such as heat, chemical reactions, or conversion of mass or a different frequency of electromagnetic energy, and include light bulbs and stars like the Sun. Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that ...
Hong Kong illuminated by colourful artificial lighting. Certain other mechanisms can produce light: Electroluminescence; Scintillation; Sonoluminescence; Triboluminescence; When the concept of light is intended to include very-high-energy photons (gamma rays), additional generation mechanisms include: Particle–antiparticle annihilation ...
Li-Fi is a light communication system that is capable of transmitting data at high speeds over the visible light, ultraviolet, and infrared spectrums. In its present state, only LED lamps can be used for the transmission of data in visible light. [2]
In 1986 Vari-Lite introduced a new series of lighting fixtures and control consoles. They referred to the new system as their Series 200, with the new lights designated "VL-2 Spot Luminaire", and "VL-3 Wash Luminaire". The Series 200 system was controlled by the Artisan console. Vari-Lite retroactively named the original system "series-100".
