BULB SOCKET AND LIGHTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/111580
Kind Code:
A1
Abstract:
A bulb socket and a lighting system, which can reduce components and dimensions and improve a force for holding a bulb, are provided. A housing (31) has an insertion hole (34) including an opening for receiving a base portion of a bulb (2), and a plurality of projection portions (34A) projecting from a deep side wall of the insertion hole (34) toward an opening side. The projection portions (34A) are opposed to each other so that the base portion (22) is sandwiched therebetween. A distance between the projection portions (34A) is formed smaller than a cross-sectional dimension of the base portion (22). When the base portion (22) is inserted into the insertion hole (34), the projection portions are elastically deformed away from each other, and contacts slidingly a surface of the base portion (22). The base portion (22) is sandwiched by a biasing force of the elastically deformed projection portions (34A) in a biasing state, and thereby the bulb (2) is held.
