Abstract
The present invention provides a lamp socket, an electric discharge lamp unit and an illuminating device which can reduce the mechanical load exerted to the lamp when the lamp is installed or transported on the lamp socket. The lamp socket 30 of the invention comprises the following components: a socket case 31; and a socket cover 32. The socket case 31 is provided with a case body 33 and an electric connection terminal 34, wherein, the case body 33 is formed with a bearing dent 33a which is used for loading a lamp power supply component 1. The electric connection terminal 34 is formed with a connection dent 34c which is used for loading a power supply terminal 3 that is coaxially projected from the lamp power supply component 1. Furthermore the electric connection terminal 34 is configured at a specified position of case body 33 adjacent with the bearing dent 33a. The socket cover 32 is formed at a position opposite with the bearing dent 33a of socket case body 33 for covering the fixing part 32a formed with a mode of lamp power supply component 1 and pressing the pressing part 32b of the power supply terminal 3. Furthermore the socket cover 32 can be latched to the socket case 31 from the upper part of socket case 31.
Description
technical field [0001] The present invention relates to a lamp socket used in a cold cathode discharge lamp, etc., a discharge lamp unit provided with the lamp socket, and a light emitting device using the discharge lamp unit. Background technique [0002] As a conventional power supply structure for cold cathode discharge lamps, etc., it is well known that a thin film made of solder is adhered to the outer peripheral surfaces of both ends of a glass bulb, and the thin film is connected to an electrode lead ( Refer to Patent Document 1). In this configuration, the lamp is held by a lamp holder constituted by a clamping plate having a spring action, and the lamp holder is electrically connected to a film as a power supply terminal. Moreover, there is known a structure in which a ring-shaped cushioning material is mounted on the outer surface near both ends of the glass tube of a cold cathode discharge lamp, and the cushioning material is supported by a case and a cover of a ...
