A flashlight is protected from damage due to shock such as occurs when a flashlight is dropped, crushed or otherwise physically abused. A plastic molding can be attached to either the front or rear portion of a flashlight or to both portions to resiliently absorb shock forces. A series of thin fins projects axially outwardly from the molding to resiliently deform upon impact so as to absorb shock and distribute the shock around the ends of the flashlight and to reduce stress concentrations around the ends of the flashlight. A series of axially-extending and radially-extending ribs further protects the flashlight from axially and radially-directed shock forces and further absorb shock forces. An optional safety crush or clearance zone can be provided between each shock absorber and the flashlight.

Disclosed is a lamp holder, which includes a front housing, a rear housing detachably connected to one end of the front housing, an end cap detachably connected to the other end of the front housing and a first connecting cap provided in the rear housing for connecting with a lamp, and further includes a compression spring, a conducting sheet and a conducting pole for contacting with an external power source. When one end of the lamp holder is connected with an external lamp socket, the conducting pole can keep a good electrical connection with the external power source due to the action of the compression spring; and when the other end of the lamp holder is connected with the lamp, the resilient sheet can keep a good electrical connection with the lamp due to the resilient sheet.

A support for mounting at least one lighting element on a safety helmet, the support comprising a body having: (i) at least one helmet attaching portion configured for directly or indirectly connecting the support to a portion of the safety helmet, and (ii) a plurality of lighting element attaching portions configured for directly or indirectly connecting the at least one lighting element to the support, wherein the plurality of lighting element attaching portions are configured to facilitate the attachment of the at least one lighting element in a corresponding plurality of positions, such that light projected from the at least one lighting element is focused or directed at a plurality of corresponding angles. An adjustable lighting system and a cable retention arrangement for a safety helmet are also disclosed.

Lighting fixtures having adjustable components configured to accommodate the application of force (e.g., from a moving patient bed) are provided. In one example embodiment, a lighting fixture can include a housing configured to house a light source. The lighting fixture can include a mounting bracket configured to attach with the housing to secure the housing to a surface. The mounting bracket can include a guide mechanism. The guide mechanism can define a guide channel. The housing is attachable to the mounting bracket such that at least a portion of the housing can move relative to the mounting bracket along the guide channel of the guide mechanism when a force is applied to the housing.

A luminaire that can resist the shock associated with a ballistics event and continue to operate. The luminaire has a base formed from high ductility aluminum. An illumination source, such as a light emitting diode array, is secured to a support of the base. A lens having a gasket is positioned over the illumination source and secured thereto with a clamp. A ballistic shield having a dual gasket is coupled to the clamp by a bezel positioned over the ballistic shield and secured to the clamp. The gaskets extending around the peripheral edges of the lens and the shield cooperate with the highly ductile aluminum base to reduce the transmission of any shock associated with a ballistic event to the illumination source and associated electronics.
