Abstract
The application relates to a sensing device and a lighting device. The sensing device comprises a sensor provided with a glass window to transmit light and is configured to sense light incident upon the sensor; a circuit board, wherein one side of the circuit board is provided with the sensor; a Fresnel lens arranged above the sensor and configured to transmit light to the sensor; and a housing made from a flame-resistant material, wherein the housing comprises an accommodation space configured to accommodate the sensor and the circuit board, and the housing is provided with a center hole to expose the glass window. By adopting the technical solution, the sensor has flame-resistant performance.
