They are usually High wattage Incandescent Lamps, Halogen Lamps, High Pressure Mercury Vapor Lamp or Low / high Pressure Sodium Lamp. Rain Proof Lamp holder with wide / narrow beam Reflectors are used for flood light.
CAN VISUAL LIGHTING CALCULATIONS USE LED LINEAR LAMPS GENERATOR
Non Permanent - Auto Switching - Emergency Generator - Battery Supply is also used. A permanent, separate, self supporting Power system which is reliable and mains rechargeable batteries in each Luminaries are provided Standby power supply required for activation of vital implements. Safety Lighting – 5% normal Lighting is provided in Potentially Hazardous areas. Escape Lighting sufficient for evacuation typically 1 – 10 lx. Emergency Lighting is required when normal lighting fails. Here moisture & dust are taken care by Gasketted Luminnaires – Completely sealed eg: in a Shower or a Laundry. In this respect explosives are as are categorized as They are encapsulated in boxes made of steel or cast iron exterior housing to avoid any explosion, sturdy resisting pressure. Luminaries in Hazardous Areas are specially designed. In High bays beyond 6m Discharge Lamps with Mirror Reflectors are employed. Highlighting Lighting = the beam projection distance and focusing ability characterize this luminaireĬoming to industrial areas if in the Interior-up to 6m Fluorescent Lamp with matt white reflector are employed. Semi-indirect Lighting =60 to 90 percent of the light is directed upward with the remainder directed downward. Semi-Direct Lighting =60 to 90 percent of the light is directed downward with the remainder directed upward. Indirect Lighting = 90 to 100 percent of the light is directed to the ceilings and upper walls and is reflected to all parts of a room. The light distribution produced by luminaries is characterized by the Illuminating Engineering Society as follows: One of the primary functions of a luminaries is to direct the light to where it is needed.
