Vehicular lamp

Abstract

A vehicular lamp including power supply connectors 20, attached to a bracket 10, and LED modules 30, attached detachably to the power supply connectors 20, respectively. The LED module includes an LED circuit board 31, an LED 32 mounted on the LED circuit board, and conduction portions 33 disposed on the LED circuit board and electrically connected to the LED. The power supply connector includes an accommodation portion 41, into which the LED circuit board of the LED module is inserted when the power supply connector is attached to the bracket, and a pair of contact terminals 50. When the LED circuit board of the LED module is inserted in the accommodation portion of the power supply connector, the contact terminals of the power supply connector contact the conduction portions of the LED module, thus making an electrical connection between the LED module and the power supply connector.

Claims

1. A vehicular lamp comprising a plurality of power supply connectors attached to a lamp body, and a plurality of LED modules attached to the power supply connectors in a detachable manner, wherein the LED module comprises an LED circuit board in a form of substantially flat plate, an LED provided on an LED carrying surface of the LED circuit board, and a pair of conduction portions provided on the LED circuit board and electrically connected to the LED,the power supply connector comprises an attachment portion attached to the lamp body, a accomodation portion into which the LED circuit board of the LED module is inserted in a direction parallel to the LED carrying surface when the power supply connector is attached to the lamp body, and a pair of contact terminals; andwhen the LED circuit board of the LED module is inserted into the accommodation portion of the power supply connector such that the LED module is attached to the power supply connector, the pair of contact terminals of said power supply connector is in contact with the pair of conduction portions of said LED module, respectively.

2. The vehicular lamp according to claim 1, wherein the contact terminals of said power supply connector engage with the LED circuit board inserted into the accommodation portion of said power supply connector, thus preventing said LED circuit board from being separated from the accommodation portion.

3. The vehicular lamp according to claim 1, wherein when said LED module is attached to the power supply connector, a surface which is on an opposite side from the LED carrying surface of said LED circuit board is in contact with a part of the lamp body.

4. The vehicular lamp according to claim 2, wherein when said LED module is attached to the power supply connector, a surface which is on an opposite side from the LED carrying surface of said LED circuit board is in contact with a part of the lamp body.
