    • A lighting panel includes a tile having a first side parallel to a principal plane of the fighting panel, a plurality of solid state lighting devices arranged on the first side of the tile and configured to emit light, a reflector sheet on the first side of the tile, and a brightness enhancement film on the reflector sheet. The reflector sheet may be arranged between the tile and the brightness enhancement film and the brightness enhancement film may be configured to increase the on-axis intensity of emitted light. A luminaire adapted for general illumination includes a lighting panel as described above, a current supply circuit configured to supply an on-state drive current to a string of lighting devices in response to a control signal, a photosensor arranged to receive light from one of the solid state lighting devices, and a control system configured to receive an output signal from the photosensor and to adjust the control signal responsive to the output signal of the photosensor.
    • 照明面板包括具有平行于战斗面板的主平面的第一侧的瓦片,布置在瓦片的第一侧上并被配置为发光的多个固态照明装置,在第一侧上的反射板 瓷砖和反光片上的亮度增强膜。 反射片可以布置在瓦片和亮度增强膜之间,并且亮度增强膜可以被配置为增加发射光的轴上强度。 适用于一般照明的照明装置包括如上所述的照明面板,电流供给电路,被配置为响应于控制信号向一串照明装置提供导通状态的驱动电流;光电传感器布置成从 固态照明装置以及被配置为从光传感器接收输出信号并且响应于光传感器的输出信号来调整控制信号的控制系统。
