Abstract
A task lighting fixture is provided for concentrating illumination on a work area beneath and offset to the side of the fixture. To accomplish this, an open reflector having a specular surface is mounted above and off to one side of the area to be illuminated. Transverse parallel vertical cross sections of the fixture are identical and comprise short and long compound curves joined together to form a cusp. The long compound curve extends toward the work area on which the illumination is to be concentrated. A U-shaped fluorescent bulb has each leg parallel to the cusp and the axes of the legs each are located on lines dissecting the cusp of the reflector.
Claims7
A lamp fixture for concentrating illumination on a work area beneath and offset to the side of the fixture including in combination:
- an open reflector, the transverse parallel vertical cross-sections of which are identical and comprise short and long compound curves joined together to form a cusp, with the long compound curve thereof extending toward the work area on which illumination is to be concentrated;
- and
- at least one elongated fluorescent bulb with its axis parallel to the cusp of said reflector and the axis thereof located on a line dissecting the cusp of said reflector, said line being substantially parallel to the offset beam of light produced by the fixture.
