Technical Field

The application relates to the technical field of lighting, in particular to a lamp.

Background

A lamp generally includes a lamp body and a light emitting assembly disposed in the lamp body. The common lamp only has a lighting function, is still in a lighting state after people leave a lighting area for a long time, wastes electric power, and cannot adapt to the ambient brightness to change the illumination of the lamp.

The patent with publication number CN217064057U discloses an intelligent lamp integrated with multiple types of sensors, which comprises a main controller, a brightness detection device, a human body detection device and a lamplight output circuit. The brightness detection device is used for detecting the ambient brightness, the human body detection device is used for detecting a human body, and the detection result is used for correspondingly controlling the light output circuit to adjust the illumination of the intelligent lamp, so that the requirements of a user in different application scenes are met.

The function realization of the multi-type sensor lamp depends on the input of the detection signal on one hand and the processing and output control of the detection signal by the main controller on the other hand. The detection signal input is usually realized by a sensor arranged on a circuit board, and the brightness detection device detects the ambient brightness by the sensor arranged on the circuit board.

The circuit board is usually built in the mounting box of the lamp and is not directly exposed to the environment, and the sensor for detecting the brightness receives the ambient brightness, so that the detection is sensitive. In addition, electronic components on the circuit board mostly adopt surface mount components, and the brightness sensor selects the surface mount components to facilitate uniform machining. Because the circuit board is arranged in the mounting box in a built-in mode, if the surface mount type component is adopted, the light inlet angle of the brightness sensor is greatly reduced. Therefore, in the prior art, the type selection of the brightness sensor is usually a plug-in type element, which is not beneficial to uniformly machine-welding the surface mount components and affects the production and processing efficiency of the lamp.
