Abstract: An electronic module comprises a ventilation device used for the efficient cooling of the components of this module while at the same time minimizing the accumulation of solid particles. To this end, a selector switch is placed between an electrical power supply unit of the module and a motor of the ventilation device. This selector switch cyclically modifies the sense of rotation of the fan in order to suck in an airflow to cool the components and expel the airflow in order to expel the solid particles located in the module and on the ventilation device.

Abstract: A light guide system for receiving and transporting ambient light by means of light guides, which system comprises at least one light collecting unit for receiving light and light transporting means to transport the received light to a location remote from the unit, is described wherein the said light collecting unit comprises a number of light guides, the light receiving ends of which are arranged in a two dimensional array of rows and columns whilst downstream these ends the light guides stepwise compose to a number of outgoing transport light guides, which number is substantially lower than the number of light receiving ends and which transport light guides constitute said light transport means. The system has a large light-collecting capability and can be made very compact and is especially very suitable for a road marking system.

Abstract: A system of a first luminaire (1) and a second luminaire (11) for lighting an object (V). Each luminaire has a housing (2; 12) provided with a plurality of tubular lamps (3, 3′, 3 ″; 13). The housing (2; 12) has a light emission window (4; 14) and a side wall (5, 5′; 15) which is perpendicular to the light emission window (4; 14). In the system, the first and the second luminaire (1; 11) abut one another with their side walls (5, 5′; 15) and/or with their light emission windows (4; 14), such that an edge (6) of the light emission window (4) of the first luminaire (1) abuts an edge (16) of the light emission window (14) of the second luminaire (11). Said light emission windows (4; 14) and said side walls (5, 5′; 15) are made from an optically transparent material. Preferably, the light emission window (4; 14) is provided with a diffusor (7; 17).

Abstract: The luminaire has a lamp housing (1) in which lamps L1, L2 of different color aspect can be accommodated, surrounded by a reflector (11) and a non-transparent, light-transmitting window (10). The window (10) gives access to a reflector housing (3) which is provided with means (31, 32; 33) for screening and directing light. In the lamp housing, light of different color or color temperature is efficiently and effectively mixed. The luminaire may have a compact shape and is suitable for illuminating rooms efficiently with light of a chosen color aspect through dimming of the lamps in relation to one another.

Abstract: The luminaire has a molded reflector body (1) comprising a reflective coating (3) with light reflective particles (10) and a binder (11) and having a substrate side (12) and an outer surface (13). The coating (3) has a smooth optical waveguiding surface due to the absence of particles (10) at its outer surface (13) and to the light-transmission properties of the binder (11). Owing to these properties, the coating (3) has a high degree of specular reflection, thereby both increasing the lumen output ratio and improving the light directional properties of the luminaire.
