Abstract: A lighting device includes a light source including at least two types of light emitting elements with different color temperatures, an optical element including a plurality of liquid crystal cells and configured to control a distribution of light emitted from the light source, and a control unit configured to control the light source. The control unit controls the optical element to change from a first light distribution state to a second light distribution state different from the first light distribution state. The control unit controls the light source so that a color temperature of light emitted in a direction perpendicular to a surface of the optical element is the same in the first light distribution state and the second light distribution state.

Abstract: A control device for a hybrid vehicle, including a mode whereby the vehicle runs using a motor only, and a mode whereby the vehicle uses both the motor and an engine. When the motor temperature of an MG(2) exceeds a threshold temperature, an ECU moves from a running mode that uses the MG(2) only, to a running mode that limits the load on the MG(2). The ECU performs control in accordance with the charging state of the battery for running, such that the work rate of an electric pump for cooling the MG(2) is increased when the charging state is higher, and the running mode that uses the MG(2) only is maintained.
