A light for room and building illumination, the light comprising an illuminant, including a circuit board including a carrier material, an insulation layer applied to the carrier material at least on one side, conductive paths applied to the insulation layer, and at least one LED that is arranged on the insulation layer and functions as the illuminant, at least one light permeable cover arranged subsequent to the LED in a light exit direction, a light housing in which the circuit board is arranged, characterized in that the circuit board is a metal core circuit board which forms the light housing.

Light for room and building illumination

A lamp holder for receiving a lamp including a LED, the lamp holder including locking cams radially extending from a lamp base; a central heat conducting element; a lamp holder housing component that is attachable by fasteners at a light fixture component; a central cut-out for receiving the lamp base, wherein the cutout is enclosed by a lamp holder housing wall which is provided with insertion grooves which are oriented substantially perpendicular to the light fixture component; locking grooves respectively originating from the insertion grooves which locking grooves are oriented parallel to the light fixture component for receiving the locking cams extending from the lamp base; and at least one spring element, wherein the holder housing component including the locking grooves is liftable against a spring force of the at least one spring element through an insertion and rotation movement when inserting and locking the lamp.

Lamp holder for receiving a lamp with holder housing component liftable against spring force

A lamp socket for supporting a light source provided with an LED, the lamp socket including a cooling element; a socket housing which includes socket contacts for electrically connecting the light source; and a lamp base which supports an LED connected to a heat conducting element and is insertable in the socket housing and includes base contacts which are connectable with the socket contacts through a contact force for providing power to the LED, wherein the cooling element on the socket side is connected with the heat conducting element on the base side with a contact pressure that promotes heat transfer, wherein the contact pressure is provided through a pressing force in order for the cooling element to absorb heat generated by the LED, wherein the electric contact between the socket contacts and the base contacts is provided so that it does not provide forces opposite to the pressing force.

Arrangement of lamp socket and lamp base

A lamp base has a projection that carries lamp contacts and has an outer surface formed with retaining formations arrayed with irregular spacing. A socket forms a recess into which the projection can be inserted with play and apertures provided with contacts engageable with the lamp contacts. Retaining formations in the socket fit with the lamp-base retaining formations in only one defined angular alignment of the lamp base and the socket. The projection has a central plug projecting toward the socket and forming a lamp key coded for a predetermined lamp wattage. The socket has a hole corresponding to the plug and itself forming a socket key coded for the maximally admissible lamp wattage for the socket. The lamp base only fits into the socket when the lamp wattage indicated by the lamp key does not exceed the maximally admissible lamp wattage defined by the socket key.

Keyed socket and lamp base

Lamp socket

The invention relates to a lamp comprising a lamp bulb () and a lamp base (), which lamp base () comprises a projection () located in a substantially central position of the lamp base () and extending in a direction away from the lamp bulb (), at least one lock-engaging portion (), and a substantially flat base surface () opposed to the lamp bulb () and surrounding the projection (), characterized in that the at least one lock-engaging portion () is located on the edge of the base surface () surrounding the projection () remote from the central projection. The invention also relates to a lampholder () for cooperation with the lamp () according the invention, the lampholder () comprising an aperture () in a substantially central position of the lampholder (), at least one counter lock-engaging portion (), and a substantially flat holder surface () surrounding the aperture, characterized in that the at least one counter lock-engaging portion () is located on the edge of the holder surface () surrounding the aperture () remote from the central aperture ().
