Embodiment Construction

[0023] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0024] MOSFET: Metal-Oxide-Semiconductor-Field-Effect Transistor (Metal-Oxide-Semiconductor Field-Effect Transistor, MOSFET) is a field-effect transistor that can be widely used in analog circuits and digital circuits ( field-effect transistor). MOSFETs can be divided into n-type and p-type MOSFETs according to the polarity of their "channels". They are usually also called NMOSFET and PMOSFET. Other abbreviations include NMOSFET, PMOSFET, nMOSFET, pMOSFET, etc. [1] Metal oxide half field effect transistors conceptually belong to "insulated gate field effect transistors" (Insulated-Gate Field Effect Transistor, IGFET). The gate insulating layer of the IGFET may be other materials than the oxide layer used in the metal oxide semiconductor field effect transistor....

Abstract

The invention discloses a photosensitive LED lamp. The photosensitive LED lamp comprises a power supply unit, an MCU (micro controller unit), a photosensitive sensor, a power adjustment unit and an LED lamp body, wherein power supply input ends of the MCU, the photosensitive sensor and the power adjustment unit are electrically connected with the power supply unit respectively; an output end of the photosensitive sensor and a control input end of the power adjustment unit are electrically connected with the MCU respectively; an output end of the power adjustment unit is electrically connected with the LED lamp body. The output brightness of the photosensitive LED lamp is adjustable, and the photosensitive LED lamp is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a photosensitive LED lamp capable of automatically identifying itself and ambient light and performing brightness compensation and a control method. Background technique [0002] At present, light-sensitive light bulbs and lamps on the market must avoid the interference of their own light when detecting external light, so as to avoid flickering caused by sensing the light emitted by themselves. Existing light bulbs or lamps can only be controlled to turn on or off the light bulbs, and the brightness of the light will not be adjusted according to the change of the external light, and the brightness compensation cannot be automatically performed according to the brightness of the external environment, resulting in energy waste. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a photosensitive LED lamp and its control method, ...
