    Detailed Description In the following detailed description, reference is made to the accompanying drawings, which are part of the latter. The illustrative embodiments described in the detailed description, the drawings and the claims are not intended to be limiting. Other embodiments can be used, and other changes can be made without departing from the scope of the claims.
    The embodiments of the present disclosure are described below with reference to the drawings. The dimensions of each element illustrated in the drawings may be different from the true dimensions of each element for the sake of convenience of explanation. Furthermore, “U, D, F, B, R and L” illustrated in FIG. 1 indicate relative directions for a vehicle 1 illustrated in FIG. 1. “U” denotes an upward direction, “D” denotes a descending direction , "F" indicates a direction towards the front, "B" indicates a direction towards the rear, "R" indicates a direction towards the right side and "L" indicates a direction towards the left side.
    Figure 1 is a perspective view of the vehicle 1 on which a headlight 10 (an example of the vehicle lamp) according to the embodiment, is mounted. The vehicle 1 comprises a right headlight 10R and a left headlight 10L as a headlight 10. The right headlight 10R is provided on the right side (R side) of the front (F side) of the vehicle 1 and the left headlight 10L is provided on the left side (L side) of the front (F side) of the vehicle 1. The right headlight 10R and the left headlight 10L are symmetrical in the configuration and therefore, the configuration of the left headlight 10L is described below, and the description of the right headlight 10R is omitted.
    Figure 2 is a schematic view of the left headlight 10L. As illustrated in FIG. 2, the left headlight 10 comprises a cover 11 and a housing 12. A lamp chamber S of the left headlight 10L is formed by the cover 11 and the housing 12.
    The left headlight 10L comprises an LED unit 20 (an example of the lamp), a LiDAR unit 30 (an example of the sensor), and a support element 40 (an example of the connector) in the lamp chamber S. The cover 11 has a light transmission factor allowing the LED unit 20 and the LiDAR unit 30 to be visible from the outside of the cover 11.
    The LED unit 20 includes a housing 21 and a lens 22. The LED unit 20 has an LED 23 (an example of the light emitting element - acronym for the expression in English "Light Emitting Diode ”in the housing 21. The LED 23 is a light emitting element which emits light towards the front F of the vehicle 1 by the lens 22. The LED 23 is provided at the level of the support element 40.
    At least part of the LED unit 20 can have a heat radiation function. For example, a surface 21a of the housing 21 of the LED unit 20 can have the function of heat radiation. A part which has the function of heat radiation is made with a material having a high thermal conductivity, or has a surface shape in which an area for heat radiation is enlarged. The material having a high thermal conductivity is a material having a higher thermal conductivity than a resin (for example, polypropylene, polycarbonate or polyester) and is, for example, a metal of aluminum, copper or silver or a resin containing a thermally conductive filler.
    The entire housing 21 can have the function of heat radiation and also the entire housing 21 can be made with a material having high thermal conductivity. In the embodiment, the entire housing 21 is formed from aluminum.
    The LiDAR unit 30 comprises a housing 31, a transmission part 32 and a LiDAR 33. The transmission part 32 is for example an infrared transmission film.
    The LiDAR unit 30 is arranged to allow the external side of the housing 31 to be visible from outside the vehicle 1 through the cover 11 and is fixed to the housing 12 by a support element (not illustrated ). The external side of the housing 31 visible through the cover 11 is for example a part of the front (side F) of the lateral surface of the left side (side L) of the housing 31. In this way, the external design of the housing 31 may be visible from outside the vehicle 1 by arranging the outside of the housing 31 so that it is visible from the outside of the vehicle 1.
    The LiDAR unit 30 has the LiDAR 33 in the housing 31. The LiDAR 33 is configured to acquire information on the front F of the vehicle 1. The LiDAR (- acronym of the expression in English "Light Detector and Ranging ”or“ Laser Imaging Detector and Ranging ”) refers to“ light detection and ranging ”or“ laser detection and ranging ”. LiDAR is a sensor that generally emits invisible light from the front side and acquires information such as a distance from an object, a shape of the object, a material of the object and a color of the object, based on the light emitted and the light returned. LiDAR 33 has a light emitting element 34 which emits light towards the front F of the left headlight 10L, and a light receiving element 35 which receives incident light from outside the left headlight 10L.
    At least part of the exterior of the LiDAR 30 unit has a heat radiation function. For example, a surface on the left side (L side) of the housing 31 near the exterior of the vehicle 1, among a surface 31a of the housing 31 (an example from the outside) of the LiDAR unit 30 has the function of heat radiation. The heat radiation function mentioned here is the same as the heat radiation function of the LED unit 20. In the embodiment, the entire housing 31 of the LiDAR unit 30 is formed from aluminum or magnesium to be configured to have the function of heat radiation.
    The support element 40 supports the housing 21 so that the housing 21 of the LED unit 20 is fixed relative to the LiDAR unit 30. In this way, the support element 40 is l support element for LED 23 and also serves as support element which connects the LED unit 20 and the LiDAR unit 30.
    In addition, the LED unit 20 and the support member 40 and the support member 40 and the LiDAR unit 30 are respectively integrated. The term "integrated" designates a state in which the mutual positions are fixed, and includes fixing with a fixing element such as a screw or molding by integral molding using for example a metal mold. In the embodiment, the housing 21 of the LED unit 20 is fixed to the support member by a screw (not shown), and the support member 40 is fixed to the housing of the LiDAR unit 30 by a screw (not shown).
    The support element 40 is configured to be able to conduct the heat generated from the LED unit 20 to the LiDAR unit 30. That is to say that the support element 40 thermally connects, the LED unit 20 and the LiDAR unit 30. The term "heat connection" means a connection through which the heat generated on one side can be conducted on the other side. The term "thermally connect" includes a state in which a contact surface is provided where two elements are in contact, and the heat is transferred through the contact surface. In one embodiment, the support element 40 is made of a material having a high thermal conductivity (for example aluminum). Then, the LED unit 20 and the LiDAR unit 30 are thermally connected by fixing the LED unit 20 and the LiDAR unit 30 in a state in which the support member 40 is thermally connected to the housing 21 and to the housing 31.
    At least part of the support element 40 has the function of heat radiation, in addition to the configuration capable of conducting the heat generated from the LED unit 20 to the LiDAR unit 30. For example , a surface 40a of the support member 40 can be configured to have the function of heat radiation. The heat radiation function mentioned here is also the same as the heat radiation function of the LED unit 20.
    Since the LED unit 20 and the LiDAR unit 30 are thermally connected, the heat generated by the LED 23 is transferred to the housing 31 of the LiDAR unit 30 by the support element 40. The heat generated by the LiDAR 33 is transferred to the housing 31 of the LiDAR unit 30. The heat transferred from the LiDAR unit 30 is released from the housing 31, since at least part of the housing 31 of the LiDAR 30 unit has the function of heat radiation.
    According to the headlight 10 having the above configuration, the LED unit 20 comprising the LED 23 and the LiDAR unit 30 are provided, the LED unit 20 and the LiDAR unit 30 are thermally connected , and at least part of the exterior (housing 31) of the LiDAR unit 30 has the function of heat radiation. Therefore, the heat generated by the LED unit and the heat generated by the LiDAR 33 can be released from the housing 31 of the LiDAR unit 30. Therefore, it is not necessary to include a separate element for radiate the heat in the headlight 10, so that the degree of design freedom of the headlight 10 can be improved.
    That is, in the related art, there is a design restriction in that one must arrange a lamp unit near a heat radiating element in order to release the heat generated by the lamp unit when designing a vehicle lamp such as a headlight. Furthermore, in a case where it is necessary to arrange a sensor in a vehicle lamp, since a space which can be used for the vehicle lamp is limited, it is impossible to arrange a radiating element sufficient heat so as not to adversely affect the sensor by heat from the lamp unit. Therefore, the sensor cannot be arranged in the vehicle lamp.
    During this time, according to the configuration of the embodiment, since the LED unit 20 and the LiDAR unit 30 are thermally connected and that at least part of the exterior (housing 31) of the LiDAR unit 30 has the function of heat radiation, the heat generated by the LED unit 20 and the heat generated by the LiDAR 33 can be released from the housing 31 of the LiDAR unit 30. Therefore, It is possible to omit a heat radiating element serving as a separate element in the related art, and thus it is possible to improve the design freedom of the headlight 10 while arranging the LiDAR unit 30.
    In addition, since at least part of the LED unit 20 has the function of heat radiation, the heat generated by the LED unit 20 can be released by the LED unit 20 and the housing 31 of the LiDAR unit 30. Therefore, it is possible to release the heat more efficiently.
    In addition, the headlight 10 of the embodiment comprises the support element 40 which connects the LED unit 20 and the LiDAR unit 30, and at least part of the support element 40 to the heat radiation function. Therefore, it is possible to release the heat more efficiently, since the heat generated by the LED unit 20 and the heat generated by the LiDAR 33 can be released from the support member 40 in addition to the heat radiation. of the housing 31 of the LiDAR unit 30.
    In addition, in the embodiment, at least part of the housing 31 of the LiDAR unit 30 has the function of heat radiation and the LED unit 20 and the LiDAR unit 30 are integrated. Thus, the heat radiating element serving as a separate element in the related art, can be omitted. Thus, the degree of freedom in the design of the headlight 10 is improved.
    In addition, it is possible to omit the heat radiating element serving as a separate element in the related art. Therefore, the number of components can be reduced.
    In addition, according to the configuration in which the entire housing 31 of the LiDAR unit 30 is formed with a material having the function of heat radiation, the heat generated by the LED unit 20 and transferred to the housing 31 by the support element 40 and the heat generated from the LiDAR 33 are released from the entire surface of the housing more effectively.
    The descriptions concerning the example in which the LED unit 20, the LiDAR unit 30 and the support element 40 have the function of heat radiation, but at least the LiDAR unit have been produced. 30 can have the function of heat radiation.
    (Modification 1) A sensor unit is not limited to the LiDAR 30 unit described above. Below, an example including a camera unit 30A as a sensor is described. Identical or equal parts are designated by the same symbols in the drawings, and their descriptions are omitted or simplified.
    Figure 3 is a schematic view of the camera unit 30A. The camera unit 30A is fixed to the housing 12 of the left headlight 10L by a support element (not shown). The camera unit 30A comprises a housing 31 and a lens 37. The lens 37 is, for example, a convex lens which projects towards the side F. The camera unit 30A has a light emission / reception element 38 in the housing 31.
    The camera is, for example, a camera which includes an imaging device such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). In addition, the camera is a camera that detects visible light or an infrared camera that detects infrared rays.
    At least part of the housing 31 (an example from the outside) of the camera unit 30A has the function of heat radiation as the housing 31 of the LiDAR unit 30. Consequently, the heat generated by the LED unit 20 and transferred to the camera unit 30A is radiated from the housing 31. It is similar to the housing 31 of the LiDAR unit 30 in that the entire housing 31 of the camera 30A can have the function of heat radiation, and part or all of the housing 31 can be made from a material having a high thermal conductivity.
    The headlight 10 is described by way of example of the vehicle lamp in the above embodiment, but the vehicle lamp of this disclosure is not limited to the headlight. The vehicle lamp of the present disclosure may be a different type from the vehicle lamps mounted on the vehicle 1.
