Abstract:
In various embodiments, a coupling component is configured to hold a lighting body inserted in a protection bulb via a mouth portion of the bulb, the coupling component having a groove for receiving the rim of the mouth portion of the bulb, the groove including sculptured formations to keep the mouth rim received in the groove spaced from the bottom of the groove to produce a discontinuous contact between the mouth rim and the groove.
Abstract:
The invention relates to electrical engineering. The aim of said invention is to reduce the production cost of a lamp and to improve the quality thereof. The inventive lamp comprises a rotatable light bulb, a light source arranged therein, a socket consisting of internal and external components connected by a retainer, a latch for preventing the socket components from rotating into each other in the same direction and an insulator which is provided with contacting plate and fixed to the internal component of the socket. The retainer is made from a spring wire in the form of an open ring, and is located in a groove, which is embodied on the side surface of the insulator, and is placed on a curved end surface of the internal component of the socket.
Abstract:
A lamp (10), which is particularly a motor vehicle head-light, comprises a burner (12) for emitting light, which is supported by a holder (16) for mechanically connecting the burner (12) with a socket (14). The holder (16) comprises a metal ring (26) surrounding the burner (12). The metal ring (26) is thermally connected to the burner (12) via a single connecting surface (40), which is in planar contact to the burner (12) over an angle of ≧350° in circumferential direction. Due to the increased heat transfer to the environment the used materials are less subjected to heat, so that the overall lifetime and the shock resistance of the lamp (10) are increased at the same time.
Abstract:
A discharge lamp device is provided that includes a light source device including a reflective surface. In the light source, noble gas not including mercury is excited to provide stable light emission and ozone or the like is prevented from being generated. This discharge lamp device includes airtight container (10) in which both end sections of a glass bulb are sealed. Airtight container (10) is filled with a discharge medium mainly including noble gas. One end section of airtight container (10) includes first electrode (11). Airtight container (10) is externally attached to insulating holder (20) having a square plate-like shape that includes penetration hole(s) (21) at one or a plurality of position(s).
