Lamp and light source device

Abstract

The present invention provides a lamp and light source device, which facilitates the operator observe the operating installation operation with eyes, the impact can be controlled in minimized range even the lamp head base impacts the lamp head, the simple and reliable, circle direction position of the lamp can be installed on the lamp head with excellent reproduction. The lamp (1) can dischargeably be installed on the lamp head base (20). Said lamp head base (20) has a convex section (22) fastening with the gap section (7) on the lamp head (4) of the lamp (1), also has a holding section (24) tabling with the lamp head holding section (9) of the lamp. The lamp (1) comprises a sealing pipe (3) connecting to two sides of the luminous tube, a cylinder lamp head (4) accomplishing the sealing tube and having a end surface on the end, and said lamp head holding section (9) connecting to the end surface of the lamp head (4) and forming with diameter less than that of said lamp head, in the lamp (1), said gap section (7) is arranged on position from the cylinder side surface (5) of the lamp head to the end surface (6).

Description

technical field [0001] The present invention relates to a lamp and a light source device, and particularly relates to a lamp and a light source device having good position reproducibility in the circumferential direction when the lamp is positioned on a base holder. Background technique [0002] Conventionally, a lamp for irradiating ultraviolet light having a predetermined wavelength is installed with the lamp positioned in a base holder. refer to Figure 10 The structure of a conventional lamp will be described. Figure 10 It is a front view schematically showing the structure of an existing lamp. Such as Figure 10 As shown, the lamp 100 is inside a luminous tube 101 made of glass, and an anode 102 and a cathode 103 are provided facing each other. Both electrodes 102 and 103 are connected to conductive metal foils 105 and 105 via conductive rods (Ride rods) 104 and 104 . The conductive metal foils 105 , 105 are sealed by glass sealing tubes 106 , 106 so as to keep airti...

Problems solved by technology

[0011] However, in the base structure of the lamp described in Patent Document 3, although the installation work can be completed from the front side of the reflector, since the structure for positioning the base and the base holder is formed on the base holding part, the operator must do it without Operate under visual conditions to make the circumferential position of the positioning part of the cap holder and the cap holding part coincide with each other.

Therefore, if the positions of the cap holding portion and the cap holder suddenly match when rotating and moving in the circumferential direction, the end surface of the cap may hit the abutting surface of the cap holder, and the impact may be transmitted to the lamp and the lamp may be damaged.

Especially in recent years, with the enlargement of the lamp power, the weight of the components (such as the anode) that constitutes the lamp is also increasing, so that the impact of the lamp base and the lamp cap will be further increased, and the possibility of lamp damage will increase.

[0012] In addition, the operator cannot visually install the lamp on the base, which is the same problem as the case with the flange described in Patent Documents 1 and 2.
