Embodiment Construction

[0047] Such as figure 1 As shown, a variable illuminance lighting device 1 for a motor vehicle compartment comprises a variable lighting device 2, a device 4 for measuring the ambient temperature in the vehicle compartment and a device 3 for controlling the variable lighting device 2, arranged On the same integrated circuit support, of the PCB (printed circuit board) type. The device 1 comprises, for example, a housing (not shown in the figure), a light emitting device 2 , a measuring device 4 and a control device 3 arranged together in the housing. The device 1 may comprise a single connector to supply power to the device 1 .

[0048] The variable lighting device 2 is adapted to selectively generate a light beam with at least one variable characteristic. The one or more variable properties may in particular be the color, the intensity or the modulation of the intensity of the light beam.

[0049] The light emitting device 2 preferably comprises a first light source 6 confi...

Abstract

The invention relates to a lighting device for the passenger compartment of a motor vehicle, comprising a variable light emission means (2) capable of selectively generating a light beam having at least one variable characteristic, a measuring means (4) for the ambient temperature of the passenger compartment of the vehicle, and a control means (3) for controlling the variable light emission means (2). The device is characterized in that the control means (3) is configured to be able to control emission of the light beams so as to vary said variable characteristic of the light emitting means according to the ambient temperature measured by the measuring means (4).

Description

technical field [0001] The invention relates to a lighting device for a compartment of a motor vehicle. Background technique [0002] In the automotive field, manufacturers look for technological innovations aimed at improving vehicle performance and safety, as well as technological innovations that produce aesthetic effects to improve a vehicle's on-board ambience or style. [0003] Therefore, there are lighting devices which have the effect of creating a certain atmosphere in the interior of the vehicle by means of the intensity or color of the lighting. Furthermore, some lighting devices provide information about parameters of the vehicle, for example on the dashboard. [0004] For example, in the case of a heating system and / or an air conditioning system, it may be necessary to give an indication of the temperature by means of a luminous signal having a specific colour. In fact, the display can be used to show the ambient temperature in the cabin, with the temperature ...
