General Information Portfolio for lighting As a manufacturer of PUR, EP and SIL based reactive resins, RAMPF offers a variety of products for the use in the lighting industry which can be used in different components of a luminaire. The applications reach from casting of sensors or ballasts over sealing of the luminaire to bonding of LED-modules into a tube. In addition, RAMPF Production Systems offers the perfectly matching mixing and dispensing equipment for these applications. RAMPF Group offers the complete solution for the lighting industry
General Information Definition luminaire: An electric lighting fixture, wall bracket, portable lamp, or other complete lighting unit designed to contain one or more electric lighting sources and associated reflectors, refractors, housing, and such support for those items as necessary.

Types of luminaires: Functions of the luminaire: > Recessed light > Surface-mounted light > Outdoor lighting > Special-purpose lights > Connection of electricity supply to lamp > Contains control circuitry for lamp > Heat dissipation from lamp > Reflection and redirection for light > Reducing glare, diffusion and baffles > Protection from the environment > Decorative appearance
General Information Structure of different luminaires: Depending on the technology of the lamp (e.g.. Fluorescent or LED), the components of the luminaire are slightly different. Fluorescent luminaire LED-luminaire
