Light-emitting device with sensing function

Abstract

The invention discloses a light-emitting device with a sensing function, which comprises a circuit board, a control board and a lower shell, wherein the circuit board is provided with the infrared sensor and a plurality of light-emitting assemblies; the control board is provided with a time adjusting device and a luminance adjusting device and connected with the infrared sensor and the light-emitting assemblies by conducting wires; the control board is arranged in the lower shell, and the lower end of the lower shell is provided a power supply input end; the upper shell of the infrared sensor is arranged above the infrared sensor and the light-emitting assemblies and used for stabling the sensing signals; and the lower end of the upper shell is embedded with the lower shell. The light-emitting device can emit a uniform and soft light source or a bright light source by the transparency of a cover of the sensor, and the infrared sensor has the function of sensing thermal radiation and takes the thermal radiation emitted by a human body as the signal supplying power to the light-emitting assemblies; when the infrared sensor can not sense the thermal radiation emitted by the human body, the infrared sensor stops supplying the power to the light-emitting assemblies by the control board so as to achieve the aim of effectively saving energy resources.

Description

technical field [0001] The present invention relates to a light emitting device, in particular to a sensor cover as the upper casing, the transparency of the sensor cover is used to make the light source have bright or uniform illumination, and an infrared sensor is used to sense heat radiation as a source of light. The signal supplied by the power supply of the light-emitting component is a light-emitting device with a sensing function for the purpose of saving energy. Background technique [0002] With the development of sensing components, the proportion of applications in daily life is gradually increasing. In the case of infrared sensing components, they are often used to start or interrupt the power supply, and to save energy by controlling light components or lighting devices. Purpose. [0003] Infrared sensors are used with lighting devices, such as traditional tungsten filament bulbs. Thermal radiation is sensed by infrared rays. When the heat source enters the sen...
