Title: A LIGHT EMITTING DEVICE WITH A LED STRIP
Abstract:
A light emitting device (1) comprising a longitudinal direction, a longitudinal axis (L) extending in the longitudinal direction, a transversal direction, a transversal axis (T) extending in the transversal direction, a height direction being perpendicular to both the longitudinal direction and the transversal direction and a height axis (H) extending in the height direction, a sleeve (2) extending in parallel with the longitudinal axis and comprising a first part (21) made of a transparent or translucent material, a second part (22) made of a diffuse material, and a channel (23) extending in parallel with the longitudinal axis and being provided in the first part of the sleeve, a reflector (3) comprising a cavity (31) extending in parallel with the longitudinal axis, a substrate (4), and a plurality of LEDs (5) adapted for, in operation, emitting light, and being arranged on the substrate (4) in such a way as to extend in a direction parallel with the longitudinal axis of the light emitting device, the substrate (4) with the plurality of LEDs (5) mounted thereon being arranged in the channel (23) of the sleeve (2). The cavity (31) is adapted for receiving any one of the first part (21) and the second part (22) of the sleeve, and the sleeve (2) being adapted for being mounted in the reflector (3) by inserting any one of the first part and the second part into the cavity such as to obtain either a spotty lighting effect or a diffuse lighting effect.
