Led Lamp System
The invention relates to an LED lamp system comprising at least one LED element ( 4 ) for emission of light, a chamber ( 1 ) with inner sidewall faces ( 2 ), which are designed to be at least partially highly reflective, with a light entrance face ( 3 ) for the emitted light and with an exit opening ( 6 ) for the light radiated into the chamber ( 1 ) and reflected from the inner side wall faces ( 2 ), and a collimator ( 7 ), which is arranged at the exit opening ( 6 ) of the chamber ( 1 ) and which has an outcoupling opening ( 9 ) facing said exit opening.
1 . LED lamp system comprising
at least one LED element ( 4 ) for emission of light,
a chamber ( 1 ) with inner side wall faces ( 2 ), which are designed to be at least partially highly reflective, with a light entrance face ( 3 ) for the emitted light and with an exit opening ( 6 ) for the light radiated into the chamber ( 1 ) and reflected from the inner side wall faces ( 2 ), and
a collimator ( 7 ), which is arranged at the exit opening ( 6 ) of the chamber ( 1 ) and which has an outcoupling opening ( 9 ) facing said exit opening.
2 . LED lamp system as claimed in claim 1 , characterized in that the light entrance face of the chamber ( 1 ) is formed by an LED radiation surface ( 3 ).
3 . LED lamp system as claimed in claim 1 , characterized in that the light entrance face of the chamber ( 1 ) is distanced from an LED radiation surface.
4 . LED lamp system as claimed in claim 3 , characterized in that a carrier ( 13 ) with a fluorescent substance ( 10 ) provided on it and/or in it and/or a wavelength filter is arranged at a distance from the radiation surface ( 3 ).
5 . LED lamp system as claimed in claim 1 , characterized in that the light entrance face ( 3 ) is larger than the exit opening ( 6 ) of the chamber.
6 . LED lamp system as claimed in claim 1 , characterized in that the inner side wall faces ( 2 ) of the chamber ( 1 ) are inclined towards the light entrance face ( 3 ).
7 . LED lamp array with a plurality of LED lamp systems as claimed in claim 1 .
8 . LED lamp array as claimed in claim 7 , characterized in that a plurality of the LED lamp systems have a common continuous carrier ( 13 ).
9 . LED lamp array as claimed in claim 7 , characterized in that the LED elements ( 4 ) for a plurality of LED lamp systems are arranged on a common base plate ( 5 ).
10 . LED lamp array as claimed in claim 7 , characterized in that the area of the outcoupling openings ( 9 ) is larger or smaller than the light entrance faces ( 3 ).
11 . LED lamp array as claimed in claim 7 , characterized in that LED elements ( 4 ) of various wavelength characteristics are used in various LED lamp systems of the LED lamp array.
