Abstract:
The present invention addresses the problem of reducing the probability of an incompatible lamp being mistakenly fitted to a socket. A lamp unit (1) is provided with a lamp (2), and a socket (3). The lamp (2) can be fitted to the socket (3). A lamp body (5) includes a first identification projecting portion (56). The first identification projecting portion (56) is of a size corresponding to the acceptable range of a first characteristic of the lamp (2), the size being smaller the larger the acceptable range of the first characteristic. A socket main body (8) includes a first identification recessed portion (84). The first identification recessed portion (84) is of a size allowing insertion of the first identification projecting portion (56). The first identification recessed portion (84) is of a size allowing insertion of the first identification projecting portion (56) of a lamp of a type for which the socket (3) is acceptable with regard to the first characteristic, and a size preventing insertion of the first identification projecting portion (56) of a lamp of a type for which the socket (3) is unacceptable with regard to the first characteristic.
