Abstract: Lightweight solid state light sources with common light emitting and heat dissipating surfaces consisting of light emitting diodes (LED) in thermal contact to light transmitting thermally conductive elements and combined with a reflector element to form a light recycling cavity, provide both convective and radiative cooling from their light emitting surfaces, eliminating the need for appended heatsinks. The lightweight self-cooling solid state light sources integrate the electrical interconnect of the LEDs and other semiconductor devices to a single substrate that is both the heatsink and the light emitting element. The elimination of heavy appended heatsinks enables these sources to be easily moved, attached and mounted on suspended ceilings without requiring separate supporting means. The low profile and nonflammable properties of the light sources allow their use on fire barrier surfaces or partitions. The light sources can easily be integrated into ceilings, ceiling grids or ceiling tiles.

A swivel angle setting unit is configured to perform a first mode in which a swivel angle of a lamp unit is set such that a light distribution pattern follows the travelling direction of the vehicle based on the curvature estimated by the curvature estimation unit, and perform a second mode in which a swivel angle of the lamp unit is set such that a shielded area created in a light distribution pattern follows the position of the vehicle detected by a vehicle position detector. A pattern determination unit determines a light distribution pattern such that the position of the vehicle detected by the vehicle position detector remains in the shielded area. A swivel angle setting unit performs the first mode when it is determined that the road is a curved road based on the curvature estimated by the curvature estimation unit, and performs the second mode when it is determined that the road is a straight road.
