  FIG. 4 is a plan sectional view of a conventional tail lamp, and the tail lamp 101 shown is provided on the left and right of the rear end of the vehicle (FIG. 4 shows only the right one) and covers the housing 102 and its opening. A lamp chamber 104 defined by the outer lens 103 accommodates a plurality of (three in cross section) LEDs 105 as light sources, a reflector 106 that reflects the light emitted from each LED 105 toward the rear of the vehicle (downward in FIG. 4), and the like. Configured. Here, each LED 105 is supported by a bracket 108, and a bezel 109 that partitions between the back door 122 and the tail lamp 101 is attached to the inner side of the housing 102.

  In such a tail lamp 101, for example, if even one of the LEDs 105 is disconnected, it is necessary to replace the tail lamp 101 as a whole, so that there is a problem that an economic burden on the user is large.

  Therefore, like the tail lamp 101 ′ shown in FIG. 5, the LED unit 110 is configured to include a plurality of LEDs 105 and a bracket 108 that supports the LEDs 105, and the LED unit 110 is detachably attached to the back side of the housing 102. In such a case, it is possible to consider a configuration in which only the LED unit 110 is removed and replaced with a new one.

  Alternatively, in the tail lamp 101 ′ adopting the configuration shown in FIG. 5, an opening 120a large enough to allow the LED unit 110 to pass through is formed in the vehicle body 120 as shown in FIG. Is necessary, the LED unit 110 may be replaced through the opening 120a of the body 120.

  However, in the case of the configuration shown in FIG. 5, the replacement of the LED unit 110 is performed by temporarily removing the tail lamp 101 ′ from the vehicle body 120 and removing the LED unit 110 from the rear surface of the removed tail lamp 101 ′. After that, since it is necessary to reattach the tail lamp 101 'to the vehicle body 120, there is a problem that a lot of time and man-hours are required.

  Further, in the case of the configuration shown in FIG. 6, since the large opening 120a cannot be formed in the vehicle body 120, the size of the LED unit 110 is restricted, and there is a problem that the replacement workability is poor. .

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a vehicular lamp in which only the LED unit can be easily replaced with good workability without replacing the whole. .

  In order to achieve the above object, the present invention supports a light source for a vehicle, which is configured by housing an LED, which is a light source, in a lamp chamber defined by a housing and an outer lens covering the opening. The LED unit is configured to include a bracket and a bezel provided on the inner side of the vehicle, and the LED unit is detachably attached to the housing from the inner side of the vehicle.

  According to the present invention, an integrated LED unit including an LED, a bracket, and a bezel is configured, and the LED unit is detachably attached to the housing from the inside of the vehicle. In this case, it is possible to easily remove only the LED unit to the inside of the vehicle with good workability and replace it with a new one without replacing the entire vehicle lamp. For this reason, a user's burden is reduced compared with the case where the whole vehicle lamp is replaced | exchanged. Moreover, since it is not necessary to form a large opening in the vehicle body for replacing the LED unit, there is no problem that the size of the LED unit is restricted.
