Abstract: 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 them 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. In some cases the light sensor saturates when the solid state light sources are active and measures the ambient light level when the solid state light sources are not active. 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.

Abstract translation: 一种用于发光和测量环境光的灯泡或灯具的方法。 该方法包括以周期性信号在灯泡中驱动固态光源（例如LED），以反复关闭和​​打开光源，在光源被关闭的情况下，以足以使灯泡出现的速率接通。 该方法还包括在光源关闭的至少一些时间期间经由灯泡中或其上的光传感器测量环境光，并且输出与所测量的环境光相关的信号。 在某些情况下，当固态光源处于活动状态时，光传感器饱和，并在固态光源未激活时测量环境亮度。 环境光电平信号可用于控制灯泡何时亮起，灯泡输出的光强度。
