382AS15 is a medium voltage incandescent lamp produced by well-known German manufacturer, OSRAM. It was introduced in 1992 and has since become a popular choice for industrial, commercial and architectural lighting applications. The lamp operates with a tungsten filament, which is encased in an inert glass cylinder surrounded by an alumina silicate arc tube. The lamp provides a diffuse glow with a warm color temperature of 2700K and has an extended lifetime compared to other incandescent lamps.

Application Field

382AS15 is suitable for a wide range of lighting applications. It is particularly popular for two major reasons: versatility and affordability. It is commonly used in places where a reliable, efficient illumination is needed, such as outdoor applications, streetlights, stadiums, auditoriums, and car parks. It is also suitable for lighting in museums, galleries, shops, and restaurants. Additionally, the lamp is widely used in the entertainment industry, in film production sets, discos, and concerts.

Working Principle

382AS15 lamps operate based on a principle known as tungsten filament incandescence. This process involves passing an electric current through a tungsten filament. In order for this process to take place, the filament must be enclosed in a protected environment so that the tungsten evaporates into a vapor. The electrical current then passes through the vapor, which turns it into a plasma. Finally, the vapor turns into light, which is emissioned through the glass shell of the lamp, creating the distinctive incandescent light that is typical of this type of lamp.

The lamp also has a prevention system, which limits the light output when the temperature of the filament gets too high. This ensures protection of the filament, and that the lamp is not damaged by becoming too hot. Additionally, the lamp is designed to operate in temperatures ranging from -10 to + 40°C.
