The bath cabinet and light fixture generally avoid the use of hardware by utilizing extruded members which interlock together. When the bath cabinet is recess mounted, the light fixture is secured directly to the mounting wall directly above the cabinet. On the other hand, when the bath cabinet is surface mounted to the wall, the light fixture is secured to the top of the bath cabinet by a clamping member.

Abstract: The device for testing angular inclination of a headlight (11) has a inclination-detecting device (14) structured as a bubble level connected with the reflector (13) of each headlight and an additional inclination-detecting device (20), which is mounted on the chassis of the motor vehicle. The inclination-detecting device (14) of the headlight indicates the deviation of the reflector (13) from horizontal. The additional inclination-detecting device (20) indicates the inclination of the motor vehicle in a vertical plane (22). To test the inclination or orientation of the reflector from a set value, the reading of the inclinaiton-detecting device (14) is compared with the reading of the additional inclination-detecting device (20). The inclination of the reflector (13) is correct, when, preferably, the inclination-detecting device (14) on the reflector indicates the same deviation from horizontal as the additional inclination-detecting device (20).

Abstract: A light fixture includes, from top to bottom, a first elongated box-shaped housing with vertical side walls, a second box-shaped housing, a coil cover, a light socket and a reflector connected to the coil cover by a pair of spaced, vertical arms. The arms connect to horizontal slots formed in opposing vertical sides of the cover, each of the opposing vertical sides having a plurality of slots to provide selectability for vertically positioning the reflector. The cover also includes a pair of inclined surfaces extending between the slotted, opposing vertical sides. During operation, heat generated inside the cover flows outwardly through the horizontal slots. Heat also flows upwardly, deflects off the inclined surfaces of the cover, contacts the bottom of the first housing, and then flows around the side walls of the first housing to extract heat therefrom.

Abstract: A fixture for a fluorescent lamp includes a diffuser panel. The diffuser panel has a frame and longitudinal elements supported by the frame and spaced apart from one another. At least some of the elements are constructed of a material to allow diffusion of impinging light. Preferred materials are translucent or transparent, such as glass or plastic. The diffuser panel also functions as an air diffuser. Provision of a nozzle in the base of the fixture allows air to flow through the panel by a sucking effect created by high velocity forced air flowing through the nozzle. This results in fixture cleaning and temperature equalization. The fixture is particularly adapted to be mounted in a moving vehicle. For this purpose, the panel is designed to be tamper-resistant and to provide easy maintenance. The diffuser panel, when a latch is opened, may be lowered by rotation to provide access to the lamp and ballast.

By this arrangement, the molded reflector and sub-miniature high-intensity light bulb mounted therein may be easily manipulated into any desired shape. The housing is releasably attachable onto a working surface adjacent to or part of an object to be illuminated.

Abstract: An area lighting fixture is constructed having a tubular pole member having a reflective interior surface and a light source mounted inside the pole and at a lower end thereof. A reflective, concave member is positioned below the light source and generally collimates light from the light source upward through the pole.
