DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a lamp device, and more particularly to a lamp device which is easy to read individual information of a lamp mounted to a lamp holder by a connector. I. Prior Art 3 Background Art Conventionally, since a light irradiation device in which a short arc type discharge lamp and a concave mirror are combined can effectively utilize the emitted light, it is often used for exposure of a semiconductor or a liquid crystal substrate. When used with a concave mirror, the spheroidal mirror can be used to converge the emitted light at a point, and it can be made into a parallel ray by using a parabolic mirror, so it is widely used. In order to obtain the aforementioned characteristics, it is necessary to make the spot of the short arc type discharge lamp correctly located at the focus of the concave mirror. Therefore, as shown in Fig. 9, a short arc type discharge lamp having a flange type socket is attached to a concave mirror having an opening at the center. Next, the mounting method of the conventional lamp will be briefly described with reference to Fig. 9. The socket structure 20 of the discharge lamp includes: a lamp holder having a cylindrical portion 21 fixed to the sealing portion 5 by an adhesive 6; a thin plate portion 40; a joint portion 30; and a fixing screw 44° lamp holder having a circular plate The portion 22 and the protruding portion 23, and the circular plate portion 22 has a hole portion 24.

Then, the disc portion 22 is fixed to the joint portion 30 by the fixing screw 44. Since the hole portion 24 has a larger diameter than the fixing screw 44, the position of the lamp shaft can be adjusted. Hereinafter, several examples regarding the aforementioned conventional techniques will be cited. The "splicer for mounting a lamp" disclosed in Patent Document 1 is a disk-shaped member for adjusting the xyz position of the entire lamp device. The flange portion of the socket structure is provided with a hole having a larger outer diameter than the four fixing screws (i.e., "bolt hole"). When the fixing screw is loosened, the disc-shaped adapter can be adjusted in the χΥΖ direction with respect to the flange portion. When the lamp is manufactured, once the spot is adjusted to a certain position with respect to the flange portion of the socket, it is only necessary to mount the discharge lamp to the light source device, so that the light of the discharge lamp is often at a certain position. The "discharge lamp" disclosed in Patent Document 2 has a flange type lamp holder that can prevent the bulb from being broken and damaged by the heat when the lamp is bright. The spot position of the discharge lamp can be adjusted by the fixing screws provided on the side of the flange-shaped adapter, and even if the discharge lamp is exchanged, the spot can be positioned at a certain position. 15 The thermal system at the time of 'lighting' spreads out through the vents of the flange type lamp holder.
