A heavy duty floodlight having an outer housing or cowling and a separate inner housing or reflector with a lens cover adapted to tightly seal the inner housing. The cowling is provided with slots in a rear inwardly extending flange, and air scoops at the front edge extending radially beyond the frame of the lens cover to permit air to circulate through the space formed between the reflector and the cowling and the surrounding air. This circulation helps to cool the floodlight and the lamp mounted therein and prevents the building up of heat between the housings regardless of the orientation of the floodlight. The reflector and the cowling may be complementarily shaped to provide venturi sections to aid in the circulation of air therebetween.
A light beam modifier device for attachment to a light beam generator apparatus such as a flashlight or a weapon light. The light beam modifier includes an easily operable clamp for facilitating securement and removal of the light beam modifier device to and from the light generator. The device provides a positive locking closure between the flip-open door and the clamp, and further includes a spring hinge for permitting at least one and preferably two flip-open positions of the door out of the path of the light beam.
Floodlight includes an optical assembly and an electrical ballast assembly detachably secured together by a pair of support brackets connected to the respective assemblies. Electrical connection between the assemblies is provided by a quick disconnect device between the support brackets. A mounting trunnion is adjustably secured to the ballast assembly support bracket.
A lighting system employs luminaires having reflectors with a fluorescent lamp support frame at the base end of the inside of the reflector. The support frame includes a plurality of extensions for holding the bases of compact fluorescent lamps arranged in a general star configuration around the center line of the reflector. The extensions are at an angle to cause the compact fluorescent lamps to follow the outwardly-flared inside surface of the reflector. A system of luminaires then provides a substantially uniform volume of light in a facility due to the patterns of overlapping light contributed by the individual luminaires.
An embedded type lighting device is formed by assembling a light body to the light body mounting base which is to be mounted to a fitting face. The light body provides the lamp structure made of a plastic material, the lamp socket, and the connector for electrical connection and mechanical connection to the light body mounting base. The light body mounting base includes a base structure made of a plastic material, a terminal block, and connection means for receiving, electrically connecting and mechanically supporting the connector of the light body. The light body is connected both electrically and mechanically to the light body mounting base by the connector. Yet, it is possible to omit a special insulation structure with regard to the terminal and the connection means by making the light body structure and the base structure of a plastic material. Thus the workability of the light body is improved and the construction of both the light body and the light body mounting base is simplified.
Described is an adjustable flood light fixture suitable for outdoor use which can adjustably cut-off unwanted glare through the use of a truncated cone shroud which can be rotated 360.degree..
