Description

  Embodiments described herein relate generally to a vehicle lighting device.

  Examples of the vehicle illumination device include a front combination light and a rear combination light. Each combination light is configured by combining lamps having different purposes. The front combination light includes a low beam headlamp, a high beam headlamp, a clearance lamp, and a turn signal lamp. The rear combination light includes a stop lamp, a tail lamp, a backup lamp, a rear fog lamp, and a turn signal lamp lamp.

  Light sources used for each lamp include bulbs and light emitting elements. Since the light emitting element has a long life and low power consumption, it is required to be used in each lamp. However, if the bulb is replaced with a light emitting element as the light source of the lamp, the vehicle safety standards of each country may not be satisfied, and the bulb is used for a lamp that cannot use the light emitting element. Therefore, in the combination light, a bulb and a light emitting element are mixedly mounted in one mounting module as a light source of each constituent lamp, and are directly mounted on a mounting module or a lamp mounted on the lamp. Since the bulb has a shorter life than the light emitting element, it is assumed that the bulb is to be replaced, and is attached to the attachment module in a detachable manner. On the other hand, since the light emitting element substrate having the light emitting element is not premised on replacement, it is fixed to the mounting module.

The substrate attachment portion 51 holds the light emitting element substrate 2 in a state where the light emitting element substrate 2 is separated from the first surface 5a. Thereby, the light emitting element substrate 2 is provided on the first surface 5a. Since the light emitting element substrate 2 is separated from the first surface 5a, heat generated when each light emitting element 21 is turned on can be easily released from the heat radiating surface to the space S. The attachment hole 52 is for inserting the power supply connector 8 and exposes the power supply connector 8 on the side opposite to the first surface 5a, that is, the first surface 5a side from the outside.

The lens 62 closes the inside of the recesses 61a to 61c. Since the lens 62 has transparency, the light from each of the light sources 21, 3, 4 and the light reflected by the reflecting surface of the reflector 61 is transmitted through the lens 62 and irradiated outside the lamp 6, that is, Irradiates outside the vehicle. The lens 62 is formed with a receiving portion 62 a that contacts the mounting module 5 via the seal member 7.

It comprises a detachable connector terminal to be connected and a cable for electrically connecting each connector terminal. Note that the substrate connecting portion 15 only needs to be able to release the electrical connection between the light emitting element substrate 2 and the connection member 13, and therefore it is sufficient that one of the connector terminals is detachable. The connection member 13c is shared by the light emitting element substrate 2 and the bulbs 3 and 4, and is connected to the negative electrode of the power supply source.

  The power supply connector 14 is electrically connected to a power supply source and supplies power from the power supply source to the light sources 21, 3, and 4.

Therefore, the assembling property can be improved as compared with the case where the mounting module 5 is provided with a plurality of power feeding connectors. Moreover, since the cable connected to the illuminating device 1B for vehicles can be bundled together, the cable can be easily routed to the vehicle. Moreover, since it can carry out only by removing a cable from the electric power feeding connector 14, when removing the illuminating device 1B for vehicles with respect to a vehicle, workability | operativity at the time of removing the illuminating device 1B for vehicles can be improved.

The board connection portion 17 is narrowed between the protrusions 17 a and 17 b as it goes from the tip of the board connection portion 17 toward the connection member 13, and the light emitting element substrate 2 is attached to the mounting module 5. Thus, the protrusions 17a and 17b are elastically deformed, and the connection terminal 24a contacts the protrusions 17a and 17b. When replacing the light emitting element substrate 2, the new light emitting element substrate 2 is brought into contact with the tip of the substrate mounting portion 51 with the connection terminal 24 a inserted between the protrusions 17 a and 17 b. At this time, the connection terminal 24a inserted between the protrusions 17a and 17b moves toward the connection member 13 between the protrusions 17a and 17b, and contacts in a state where the protrusions 17a and 17b are elastically deformed. To do. The light emitting element substrate 2 is attached to the mounting module 5 with a plurality of screws 23 in a state where the substrate connecting portion 17 is in contact with the substrate wiring portion 24. At the same time that the light emitting element substrate 2 is mounted on the mounting module 5, the substrate connecting portion 17 electrically connected to the connecting member 13 is electrically connected to the substrate wiring portion 24. That is, like the first modification, the workability and work time for replacement can be improved.

  Moreover, in the said Embodiment 2, Modification 1-3, although the connection member 13 was made into the bus bar, it is not limited to this. FIG. 9 is a diagram illustrating a fourth modification of the vehicle lighting device according to the second embodiment. As a fourth modification, the connecting member 18 may be a cable instead of a bus bar. There are a plurality of connecting members 18, one end of each connecting member 18 a to 18 g is electrically connected to the power supply connector 14, and the other end is connected to the light emitting element substrate 2 and the sockets 11 and 12. The connection members 18a, 18b, and 18c supply power and control signals from the power supply source to the light emitting element substrate 2 through the single power supply connector 14. The connecting members 18d and 18f supply power from the power supply source to the valve 3 via the power supply connector 14 and the socket 11. The connection members 18e and 18g supply power from the power supply source to the valve 4 via the power supply connector 14 and the socket 12. The connection members 18a, 18b, and 18c are detachably attached to the light emitting element substrate 2 at the end on the light emitting element substrate 2 side. A connector terminal for electrically attaching and detaching the light emitting element substrate 2 to the connection member 18 is electrically connected to the end portion on the light emitting element substrate 2 side.

  In the above-described embodiments and the like (Embodiments 1 and 2 and Modifications 1 to 4), cables electrically connected to the power feeding connectors 8 and 14 and the sockets 9 and 10 may be detachably attached. Further, when the concave portions 61 a to 61 c are closed by the lens 62, the reflector 61 is provided with the receiving portion 62 a, the seal member 7 is provided between the attachment module 5 and the reflector 61, and the reflector 61 and the lens 62 are attached. A space formed by the module 5 may be sealed. Further, when a means for suppressing foreign matter and water from entering the space S between the mounting module 5 and the lamp 6 is separately provided, for example, a seal member is provided between the vehicle and the lamp 6. If it is, the seal member 7 between the mounting module 5 and the lamp 6 may be omitted.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the invention described in the claims and equivalents thereof as well as included in the scope and gist of the invention.
