A light unit comprising: a fire resistant housing (7) having a central symmetry axis; a support (2) located in the housing; a main lamp unit located axially on the support (2); and wherein the housing (7) comprises a back section (30) having front and rear surfaces, one or more sides and a forwardly opening aperture through which light from the main lamp unit passes to the exterior; the support (2) being located in contact with or adjacent a front of the back section (30); a heat sink (4) located in contact with or adjacent a rear of the back section (30); the back section (30) having one or more apertures (31, 32) communicating between the front and rear of the back section (30); a thermally conducting element (36) in contact with the heat sink (4), the element (36) extending through a respective aperture (31,32) and contacting the support (2) adjacent a rear portion of the main lamp unit.
摘要:
A vehicle lamp includes: an infrared light semiconductor light source which emits infrared light; a white light semiconductor light source which emits white light; and a control unit including: a current supply circuit which supplies a light source driving current to each of the infrared light semiconductor light source and the white light semiconductor light source; and a light source abnormality detecting unit which detects abnormality of the white light semiconductor light source and stops a driving operation of the infrared light semiconductor light source when the abnormality is detected.
摘要:
A lamp connector assembly for an ultraviolet (UV) water treatment vessel includes a sealing collar configured to connect to a headplate of the UV treatment vessel. The sealing collar includes a first lamp collar interlock feature. A lamp collar is configured to releasably connect to the sealing collar. A release member is moveably connected to the lamp collar. The release member has a locked configuration that engages the first lamp interlock feature to prevent movement of the lamp collar relative to the sealing collar and an unlocked configuration that disengages the first lamp interlock feature to allow movement of the lamp collar relative to the sealing collar.
摘要:
A safety end cap assembly (100, 200, 25, 300) to be arranged on an end of an elongate housing (3) of a LED tube. The safety end cap assembly has an end cap base element (101, 201, 29, 301) and an end cap cover element (103, 203, 303, 43) arranged slidable on the end cap base element (101, 201, 29, 301) along said longitudinal axis between a protracted position and a retracted position. The safety end cap assembly further has a switch button (41, 113, 213, 313), switchable between a closed position and an open position, a first spring mechanism (45) for urging the end cap cover element towards the protracted position, and a switch opening mechanism configured such that in case the switch button is in the closed position and the end cap cover element moves from the retracted position towards the protracted position over a predetermined distance, the switch button is switched to its open position.
