A light source device having a large cooling action on the base member of a discharge lamp. A connector on the sides of the power supply and the air blower and the base-side connector of a discharge lamp are connected to each other through a connection cable having a power cable in which an air blow pipe is contained. An electric power is supplied from the power supply to a base part through the power cable of the connection cable, the base-side connector and a flow passage bending member. The cool air from the air blower is supplied to the groove part of the base part through the air blow pipe of the connection cable, the base-side connector and an air blow passage in the flow passage-bending member.

An end cap of a lighting tube includes a first assembly member and a second assembly member. The first assembly member includes a first shell, several recesses, and two first position-limiting elements. The first shell has a first central-securing element, and the first shell forms a first area and a second area. The two first position-limiting elements are disposed on the first area. The second assembly member includes a second shell, a first elastic element, a second elastic element, and two positioning elements. An end of the second shell is connected to a lighting tube and a second central-securing element of the second shell is secured with the first central-securing element. The first elastic element is disposed on the second shell. The second elastic element is disposed on the second shell. The two positioning elements are disposed on the second shell.

A mercury-free metal halide lamp for a vehicle according to an embodiment includes an airtight vessel 1 provided with a light-emitting part 11 with a discharge space 111 inside, a metal halide 2 and a rare gas sealed in the discharge space 111, and a pair of electrodes 32 disposed so that the tip ends of the respective electrodes 32 face each other in the discharge space 111. The electrodes 32 and the discharge space 111 do not contain thorium. When an electric power supplied to the lamp during a stable lighting period is represented by P (W), a value obtained by adding up the electric power supplied to the lamp during a period between 1 second and 40 seconds after the startup of the lamp is represented by WL (W), and the diameter of the electrodes 32 is represented by D (mm), P (W) satisfies 20≦P≦30 and WL/D (W/mm) satisfies 4300≦WL/D≦7400.
摘要:
A fluorescent light includes a base, a lamp seat, and an illuminating tube. The lamp seat includes a cover securely mounted to the base and a housing that receives an illuminating circuit. The illuminating tube has two ends mounted to the base. The illuminating tube defines a compartment in which the housing is received. The fluorescent lamp can be used with a lamp-mounting base for a conventional incandescent lamp without increasing the overall length of the whole illuminating system while providing improved illumination effect.
