A white light generating portion is comprised of a gas discharge light source and a rotated cylindrical lens. A red light generating portion is comprised of a plurality of light emitting diodes.
An apparatus for lighting includes a fixture having a center axis. The apparatus includes a first light source disposed in the fixture which produces light along the center axis. The apparatus includes a grid having slots which reflect the light radially outward from the center axis extending from the fixture along the center axis and illuminated by the first light source. The apparatus includes a translucent element extending from the fixture along the center axis and disposed about and in spaced relationship with the grid. The apparatus includes a second light source disposed between the element and the grid. A method for lighting includes the steps of producing light along a center axis of a fixture with a first light source disposed in the fixture. There is the step of reflecting the light radially outward from the center axis with a grid having slots extending from the fixture along the center axis and illuminated by the first light source. There is the step of transmitting the light through a translucent element extending from the fixture along the center axis and disposed about and in spaced relationship with the grid. There is the step of producing light with a second light source disposed between the element and the grid.
A vehicle headlamp (10) has a first light source (12) for illuminating an area forward of the light source (12). The first light source (12) is preferably a filamented tungsten halogen capsule. The first light source (12) is arrayed along a longitudinal axis (14) and emits substantially white light. A second light source (16) in the form of a plurality of light emitting diodes is arrayed about the first light source (12), and the second light source (16) emits light in directions substantially normal to the longitudinal axis (14), for example, along an axis (16a) for providing essentially aesthetic illumination. The aesthetic illumination can be used with or without the first light source being illuminated.
A dome light is disclosed which utilizes a rotating knob with `on` and `off` positions to toggle between having either a halogen bulb on or a plurality of red LEDs on, or both off. Dual D-type flip-flops toggle the dome light between states in response the changes of the knob between the `on` and `off` positions. The plurality of red LEDs utilize at least one current regulator to maintain a constant level of illumination. When the halogen bulb is on, further rotation of the knob varies a potentiometer which controls the duty cycle created by a pulse width modulator. The pulse width modulator causes the halogen bulb to be on for portions of each cycle; the longer the `on` time during each cycle, the greater the apparent intensity of illumination by the halogen bulb.
