Description

Technical field

The invention relates to the technical field of lamps, and in particular to a built-in intelligent induction lamp.

Background technique

LED lamps are a new type of semiconductor solid-state light source with significant advantages such as low power consumption and long life. In the context of increasing global resources and increasing environmental pressures, LED lighting has been recognized as an important way to save energy. Sensing technology is a widely used luminaire control technology. It can sense the light intensity in real time through sensors or collect the infrared rays generated by pedestrians to transmit signals to the control circuit board. By controlling the circuit board, it can control the operation of LED lights. Sensing technology lamps are intelligent sensor lights.

Generally, the existing sensor is basically installed outside the induction lamp. When the human body passes or the light is insufficient, the induction lamp is turned on by controlling the control of the circuit board. In actual use, when the external light is weak, if the induction light is in the state of illumination, the sensor detects the light emitted by the induction lamp itself, and at this time, controls the signal received by the circuit board from the sensor. It will be mistaken that the external illumination is sufficient and the control sensor is extinguished. Since the sensor is detected in real time, the sensor immediately transmits the weak external signal to the control circuit board, and the control circuit board immediately controls the induction lamp to emit light. Thus, the induction lamp will remain at The chaotic mode of the shell, the extinction, the lighting, and the extinction, that is, the sensor lamp is in a flashing state, so that the sensor lamp is in an unreliable and unstable working state, and is unfavorable to the user's vision, greatly reducing the comfort of use of the product.
