A method for a light bulb or fixture to emit light and measure ambient light. The method includes driving solid state light sources, such as LEDs, in the bulb with a cyclical signal to repeatedly turn the solid state light sources off and on, where the light sources are turned off and on at a rate sufficient for the bulb to appear on. The method also includes measuring ambient light via a light sensor in or on the bulb during at least some times when the light sources are off, and outputting a signal related to the measured ambient light. The ambient light level signal can be used to control when the light bulb is on and an intensity of light output by the bulb.

The light fixture unit includes an outer contour portion to be built in a wall portion including a ceiling, and a first fitting portion. The light source unit includes a light source section, an additional functional section, and a second fitting portion, the light source section emitting light for illumination, the additional functional section having an additional function other than the illumination, the second fitting portion detachably fitting with the first fitting portion, the light source unit being disposed in the outer contour portion by the fitting.

In one embodiment, an overhead street light (a luminaire) is formed that has an asymmetric light intensity distribution, where the peak intensity is greatest along the direction of the street, lower directly across the street, and much lower on the house side of the street. Around the edge of a circular transparent light guide are white light LEDs that inject light into the light guide. To help control the asymmetry of the light intensity distribution, sawtooth-shaped grooves are formed in the light guide surface opposite to the light-emission surface and parallel to the street. Gaussian diffusers are used to partially diffuse the light. By proper selection of the grooves, the Gaussian diffuser, and the relative amounts of light emitted by LED segments around the light guide, the desired asymmetrical light intensity distribution is achieved while a direct view of the light exit surface appears as a uniform light.
