Description

TECHNICAL PART

The present invention relates to coolable LED lights according to the preamble of the independent claims. Such are basically known for a long time.

The CH 585 882 A discussed already in 1975 a fundamental coupling of light sources and cooling circuits for apartments; in the same sense is the EP 0 423 920 A which specifically provides liquid coolant for use.

The JP 02061905 A discloses in 1990 a light source for illuminating an ice exhibition. In order to minimize heat radiation here, the lamp is mounted on the ceiling side so that an IR filter throws the harmful heat radiation back and the lamp itself is enclosed by a housing, which also serves as a flow channel for cooling air.

The US 4,949,232 discloses in 1990 a lamp for exhibition purposes, which has a light pipe with back reflector, wherein the reflector is coupled to a heat conductor, which in turn derives the heat back.

The DE 92 05 212 U1 discloses in 1992 a light bar for halogen light sources, in which all components are arranged in a downwardly closed aluminum profile and suspended on the ceiling side. The metal profile offers the possibility of convective discharge of heat generated by light sources and associated transformer, which is also mounted on the back.

The JP 101 441 13 A discloses in 1998 a signal lamp having LED bulbs with associated convective cooling channels, wherein the cooling channels are arranged chimney-like warm air. The DE 201 08 980 U1 looks in the same direction ventilation slots for cooling a headlight before.

DESCRIPTION OF THE PRIOR ART

Generic lights include coolable LED bulbs.

From the KR 10 2005 008 639 1 A For example, a PCB carrier is known that can provide improved heat rejection from front-mounted LEDs through a back-mounted heat pipe. The DE 20 2011 108 542 U1 provides in the same direction a back, heat-conducting coupling of an LED carrier with a metallic housing. The aluminum rail designed in this way serves both as a heat dissipation and as a shapely housing, which is adaptable with scatter or grid disks in its emission characteristics. The WO 2011 110 160 A suggests in the same sense to couple a lamp directly with a device for cooling.

A disadvantage of the generic lights that they regularly provide a rigid coupling of lighting and cooling device in an assembly. The inherent advantage of LEDs, namely the ease of positioning with the simplest means, is reduced by the heatsink and cooling means: the increased weight makes mounting with the simplest means difficult.

It was therefore an object of the present invention to overcome the disadvantages of the prior art and to provide a coolable LED luminaire which, despite the coolability of a high-power luminous means, is able to provide selectable arrangements in space.
