The invention provides a human body pyroelectric intelligent LED illuminating lamp. The human body pyroelectric intelligent LED illuminating lamp comprises a power supply, an LED lamp unit, a human body pyroelectric sensing unit, a signal amplifying circuit and a switch controlled circuit; wherein the LED lamp unit, the hum body pyroelectric sensing unit, the signal amplifying unit and the switch controlled circuit are connected with the power supply. An outer cover of the human body pyroelectric sensing unit is provided with a Fresnel lens. The switch controlled circuit comprises an LED driving unit and a sensor driving unit. The sensor driving unit is connected with the human body pyroelectric sensing unit and the signal amplifying unit. The signal amplifying unit is connected with the LED driving unit. The LED driving unit is connected with the LED lamp unit. The power supply is a button cell. The human body pyroelectric intelligent LED illuminating lamp has a small size, and a convenient suspended or plastering mode can be adopted in mounting. Small size is realized and mounting in a decorated space is facilitated. No original decoration is damaged and no read is required. The human body pyroelectric intelligent LED illuminating lamp can be conveniently mounted at a specific position according to the requirement. Not only are an energy saving effect and an environment-friendly performance realized, but also high convenience can be generated for a person in a dark environment.
Description
technical field [0001] The invention relates to an LED lighting lamp, in particular to a human body pyroelectric intelligent LED lighting lamp. Background technique [0002] In basements, corridors, stairs and other places, voice control or light control is often used to control the lighting on or off. For example, the utility model patent with the patent application number 200520118497.3 discloses an induction LED lamp, the utility model patent with the patent application number 200620014274.7 discloses a solar pyroelectric induction control LED lamp, and the utility model patent with the patent application number 200720036738.9 The patent discloses an infrared light-controlled LED induction lighting. The light control method of these LED lights is only suitable for moving objects. If a person stays in the lighting area for a long time, the light source cannot maintain a normal open state. Another example is the utility model patent with the patent application number 20122...
