摘要：
A light source package for selectively interrupting power to a light source is provided. An optical element is positioned to reflect a reflected portion of the light from the light source. The reflected portion impinges upon a base that includes a roof panel with a light source side and a sensor side that is opposite to the light source side. The light source side of the roof panel receives the reflected portion of the light and transmits a transmitted portion of the light through the roof panel. The sensor side of the roof panel includes a recess in which a sensing component is located. The sensing component receives the transmitted portion of the light and is configured to interrupt power to the light source when the transmitted portion of the light is below a threshold.
