The invention relates to an electric light source technology, in particular to a wardrobe uninterrupted-power-supply human body infrared induction dimming LED lamp. The wardrobe uninterrupted-power-supply human body infrared induction dimming LED lamp comprises a light-emitting diode LED lamp, an AC power rectifier, a storage battery, a voltage-stabilizing chip, an infrared sensor, a light-out delay circuit, a relay J1, a relay J2, a relay J3, a dimming pulse generator and a pulse PWM dimming driving chip, wherein an output of the infrared sensor is connected with the light-out delay circuit, an output of the light-out delay circuit is connected with the relays, a switch S switches AC power supply and storage battery power supplying modes, a relay contact J1-1 is connected with an input end of the voltage-stabilizing chip, an output of the voltage-stabilizing chip is connected with a power supply end of the dimming pulse generator, an output of the dimming pulse generator is connected with an enable end of the pulse PWM dimming driving chip, and an output of the pulse PWM dimming driving chip is connected with the light-emitting diode LED lamp. The wardrobe uninterrupted-power-supply human body infrared induction dimming LED lamp is suitable for uninterrupted-power-supply illumination in a wardrobe, is automatically turned on when a person approaches the wardrobe to choose or store clothes, and is turned off in a delayed manner, thereby saving time and effort.
Description
technical field [0001] The invention relates to electric light source technology, in particular to a wardrobe uninterrupted power supply human body infrared induction dimming LED lamp. Background technique [0002] Wardrobe stores clothing for all seasons. It is time-consuming and laborious to find clothing that is ready for use without suitable lighting. The brightness is too strong or too weak and the lack of dimming affects selection. The wardrobe lighting uses AC power supply, and power failure affects the selection or storage time. Contents of the invention [0003] The purpose of the present invention is to provide a kind of uninterrupted power supply for human body infrared induction adjustment of wardrobe when the AC power supply is cut off. Light LED lights. [0004] Technical solution of the present invention: including light-emitting diode LED lamps, AC power rectifier and storage battery, model 7805 voltage regulator chip IC 1 , model AMNI infrared sensor, mo...
