Lamp for installation at ceiling or wall in e.g. public building, has printed circuit board made of heat-conductive material and connected with base part at edges running in longitudinal extension of lamp housing in heat conductive manner

摘要

The lamp (1) has a bulb holder enclosed with LED bulbs and divided into profile-like front-side transparent hoods (5) and metal rear base parts (4) in connection with the bulb holder over a circumference transverse to a longitudinal extension. The bulb holder comprises a printed circuit board made of a heat-conductive material. The printed circuit board is connected with the base parts at edges running in the longitudinal extension of an elongated lamp housing in a heat conductive manner. The printed circuit board with edge strips against the base parts in a planar manner. The base part is designed as a light metal profile i.e. aluminum profile. The end parts are made of plastic.
