Abstract: The present invention relates to an electric fluid-heating device (1), in particular for a motor vehicle, comprising a housing having a first fluid-circulation chamber (21), at least one electric heating element (4) for heating the fluid in said first chamber (21), an electronic board (81) for controlling a current circulating in said electric heating element or elements (4), at least one thermal sensor. Said device is characterised in that the thermal sensor or sensors are positioned on the electronic board (81) and thermally connected to the first chamber (21) via a heat sink (9).

Abstract: The invention relates to a device for electrically heating (1) a liquid, comprising a heating body (11), and a housing (3) defining, at least in part, a chamber (30) for circulating the liquid, the heating body (11) comprising at least one electric heating element (7, 9) extending in the chamber (30) and attached to an inner wall of the device defining, at least in part, the chamber (30) for circulating the liquid, so as to form a first mechanical connection. According to the invention, the electric heating device (1) comprises at least one mechanical connecting element (21) arranged in the chamber (30) and mechanically connecting the at least one electric heating element (7, 9) to an inner surface of the housing (3) extending opposite the heating body (11), so as to form a second mechanical connection separate from the first mechanical connection.

Abstract: Heating body (I) for a device (16) for electrically heating liquid, said heating body (I) comprising at least one first helical heating element (4) defined by a diameter (di), a second helical heating element (5) defined by a diameter (d2), and a base (2) carrying the first and the second heating element (4, 5), characterized in that the first diameter (di) is greater than the second diameter (d2), and in that the first heating element is disposed around the second element. The heating body (I) can be configured so as to comprise three heating elements, or more, arranged such that the size in terms of length is limited, and could include a core, disposed so as to be surrounded by all of the different heating elements, reducing the volume of liquid inside the chamber (15) in which the heating body (I) is housed.

Abstract: A lighting module including a light source with a carrier and at least two light emitters that are placed on the carrier and that have a common electrode; and a power-supplying electrical circuit for supplying the light emitters with power. The power-supplying electrical circuit includes a current source that is connected, via switches, to the light emitters of the light source, and a control circuit for controlling the switches, so as to allow each of the emitters to be selectively supplied with power by the current source.

Abstract: The invention relates to a light module including a laser source capable of emitting a coherent light beam of given wavelength, a first sensor capable of picking up a first light signal of a wavelength lying in a first band of wavelengths centered around the given wavelength and a second sensor capable of picking up a second light signal of a wavelength lying in a second band of wavelengths centered around a wavelength distinct from the given wavelength. In particular, the light module includes a detection module capable of comparing at least one value that is a function of the signals to a threshold value and of commanding the stopping of the laser source as a function of the comparison.
