A lamp is a device that produces illumination by using a wick soaked in combustible material or other light-producing instruments such as gas and electric lamps. Lamps were invented at least as early as 70,000 BCE and have evolved over time to use different materials and designs. In this article, we will explore the various types of materials that are used to build a lamp, and their properties and functions.What is a Lamp Material?A lamp material is any substance that is used to construct a lamp

A xenon arc lamp is a type of gas discharge lamp that produces light by passing electricity through ionized xenon gas at high pressure. Xenon arc lamps have a smooth emission curve in the ultraviolet to the visible spectrum, with characteristic wavelengths emitted from 750 to 1000 nm. They produce a bright white light that closely mimics natural sunlight, which extends their applications into various fields such as film, daylight simulation, solar testing, and research. Xenon arc lamps can be di

A metal halide lamp is a type of high-intensity discharge (HID) lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides. Metal halides are compounds of metals with bromine or iodine. Metal halide lamps have high luminous efficacy, color rendition, and long lifespan. They are widely used for general lighting purposes both indoors and outdoors, such as commercial, industrial, and public spaces, parking lots, sports arenas, factories, and retail

Street lighting design is the design of street lighting such that people can safely continue their travels on the road. Street lighting schemes never brings the same appearance of daylight, but provide sufficient light for people to see important objects required for traversing the road. Street lighting plays an important role in: Reducing the risk of night-time accidents Assisting in the protection of buildings/property (discouraging vandalism) Discouraging crime Creating a secure environment f

Tunnel lighting is necessary to solve the problem of abrupt adaptability of the environment inside the tunnel. It is necessary to balance the adaptability of the inside and outside luminance for the person entering or exiting the tunnel. This design is based on certain critical length of the tunnel.Why Tunnel Lighting is Needed? At night a tunnel may be lighted in such a way that it would be similar to a stretch of open road. Again the visual performance and visual comfort aspects of thetunnel l

General Interior Lighting in Past and PresentWe know electric lighting in the early days when school rooms, offices and other general work areas were lighted by prismatic or translucent globes. These were suspended from the ceiling and housing incandescent lamps in such a way that such units provided lumens both directly and indirectly to the work plane. It happened through reflections from the room surfaces. Again the Glass enclosing globes were widely used to have high luminance. Thus this lig

Flood lighting is a type of artificial lighting that uses high-intensity, broad-beamed light sources to illuminate large areas such as outdoor playing fields, stadiums, buildings, monuments, landscapes, and other architectural features. Flood lighting can create dramatic effects, enhance visibility, improve safety and security, and provide aesthetic appeal.In this article, we will explain what flood lighting is, how it works, what are its main characteristics and types, and what are its applicat

Hospital lighting is an essential aspect of healthcare facilities that affect the well-being and performance of patients, staff, and visitors. Hospital lighting design should consider the specific needs and preferences of different spaces and users, as well as the energy efficiency and sustainability of the lighting system. In this article, we will discuss the main purpose and objectives of hospital lighting, the required illuminance levels and types of luminaires for various hospital areas, and

What is an Arc Lamp?An arc lamp is a type of electric lamp which produces light by creating an arc in the space between two electrodes when electrical energy is supplied. In the early 1800s, Sir Humphry Davy invented the first arc lamp. In that first lamp, two electrodes of carbon were used. The arc was produced between the electrodes in the air. It was used in searchlights, movie projectors (high-intensity light).Nowadays, gas discharge lamps are widely used. It is preferred to carbon arc lamps

Required Wiring ComponentsA tube light is not connected in the supply main directly. Although it operates at 230 V, 50 Hz, some auxiliary electrical components are used to insert in this installation to support the tube light operational principle. The total electrical components for single tube light installation are Choke: it is electromagnetic ballast orelectronic ballast Starter: Small neon glow up lamp Switch WiresPlease ensure that you take the appropriate electrical safety precautions whe
