Abstract
A light-adjustable LED table lamp comprises an LED table lamp body, a power circuit converts 220V alternating currents into 12V direct currents to supply electricity to an MCU control unit and the LED lamp body, the MCU control unit is electrically connected with a key circuit which is a touch screen type key circuit, key signals of the key circuit are transmitted to the MCU control unit which adjusts intensity of light of the LED lamp body according to the key signals, the LED lamp body is arranged inside a lampshade, the key circuit, the MCU control unit and the power circuit are arranged inside a lamp holder, and keys of the key circuit are exposed out of the surface of the lamp holder. The light-adjustable LED table lamp achieves light adjustment of the LED lamp body through the touch screen keys, and is provided with a USB interface to charge a mobile phone.
Description
Technical field:
The utility model relates to the desk lamp technical field, more specifically to a kind of LED desk lamp that can light modulation.
Background technology:
The LED desk lamp of existing tunable optical is when light modulation, and majority pulls with hand the light modulation key and realizes the light modulation to the LED lamp, and this regulative mode is not suitable for child and uses, and lacks simultaneously and changes sense.General desk lamp does not configure USB interface and charges the phone.
The utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of LED desk lamp of tunable optical is provided, and it realizes the light modulation of LED lamp by the touch-screen button, dispose USB interface simultaneously and charge the phone.
Technology solution of the present utility model is as follows:
A kind of LED desk lamp of tunable optical, comprise the LED lamp, power circuit is converted to the 12V direct current to MCU control module and the power supply of LED lamp by 220 alternating currents, the MCU control module is electrically connected with key circuit, key circuit is the touch-screen type key circuit, the push button signalling of key circuit flows to the MCU control module, the MCU control module is adjusted the light power of LED lamp according to this push button signalling, the LED lamp is arranged in lampshade, key circuit, MCU control module and power circuit are arranged in lamp socket, and the button of key circuit exposes holder surface.
The 12V direct current of described power circuit is exported the 6V charging voltage at USB interface after the reduction voltage circuit step-down.
Described MCU control module is single-chip microcomputer.
The beneficial effects of the utility model are:
It realizes the light modulation of LED lamp by the touch-screen button, dispose USB interface simultaneously and charge the phone.
The accompanying drawing explanation:
Fig. 1 is circuit frame principle figure of the present utility model;
Fig. 2 is structural representation of the present utility model.
In figure: 1, power circuit; 2, MCU control module; 3, key circuit; 4, LED lamp; 5, reduction voltage circuit; 6, USB interface; 7, lamp socket; 8, lampshade.
The specific embodiment:
Embodiment: see Fig. 1, shown in 2, a kind of LED desk lamp of tunable optical, comprise LED lamp 4, power circuit 1 is converted to the 12V direct current to MCU control module 2 and 4 power supplies of LED lamp by 220 alternating currents, MCU control module 2 is electrically connected with key circuit 3, key circuit 3 is the touch-screen type key circuit, the push button signalling of key circuit 3 flows to MCU control module 2, MCU control module 2 is adjusted the light power of LED lamp 4 according to this push button signalling, LED lamp 4 is arranged in lampshade 8, key circuit 3, MCU control module 2 and power circuit 1 are arranged in lamp socket 7, the button of key circuit 3 exposes lamp socket 7 surfaces.
The 12V direct current of described power circuit 1 is exported the 6V charging voltages at USB interface 6 after reduction voltage circuit 5 step-downs.
Described MCU control module 2 is single-chip microcomputer.
Operation principle: the touch-screen type key circuit can adopt hand to touch button, the power that the MCU control module is regulated the LED lamp wiring automatically according to the number of times touched, also the LED lamp can be divided into to several rows simultaneously, determine that by touching number of times bright which bank light of which bank light is dark, thereby reach the purpose of light modulation, its light regulating is very convenient, and rich variation sense, has enriched people's life.Also very convenient when people charge at home simultaneously, can directly charge the phone by USB interface.
