Abstract
一种琴键式多档LED调光台灯，它是将市电220V经三组不同电参数的RC阻容限流电路，并由桥式整流器转换成直流高压点亮LED发光二极管串联组件，同时由多档亮度调节开关选择不同电流，达到发光二极管“强、中、弱”变化，从而取代白炽灯的调光，其电能转换成光能全过程均为低功耗。
A piano key type multi-level LED dimming table lamp, which is a 220V commercial power through three sets of RC resistance-capacity current limiting circuits with different electrical parameters, and is converted into a DC high voltage by a bridge rectifier to light up LED light-emitting diodes in series. The multi-level brightness adjustment switch selects different currents to achieve "strong, medium, and weak" changes in the light-emitting diodes, thereby replacing the dimming of incandescent lamps, and the entire process of converting electrical energy into light energy is low power consumption.
Description
Affiliated technical field: the utility model relates to a kind of lamp dimmer device, many grades of LED lamp dimmers of especially a kind of piano type.
Technical background: at present, its light source of lamp dimmer civilian on the household electrical appliance market of various places nearly all is an incandescent lamp bulb, and the exploitation H of minority producer energy-conservation cast is also arranged once in a while.Although these desk lamps with dimmer switch are awfully hot pin on market, people like very that also its power consumption is bigger, especially incandescent lamp bulb.Along with the new product development of electronic applications, it is the LED light-emitting diode that a kind of novel electric light source is arranged, and its power consumption approximately is 1/100 of an incandescent lamp bulb, has great luminous efficiency and extremely long useful life.
In order to respond the call of the national energy savings that proposes, the utility model provides a kind of new LED lamp dimmer, it can replace all kinds of desk lamps with dimmer switch on the market fully, brightness does not weaken, save remarkable benefit, especially burn in the other nothing heat of desk lamp and feel, have characteristics such as low-power consumption, noiseless and volume are little, allow 21 century this revolution of green illumination enter each family.
Summary of the invention: technical solution adopted in the utility model is: input 220V civil power is through the RC capacitance-resistance current-limiting circuit by three groups of different electrical parameters, and converts dc high voltage to by bridge rectifier and light luminescence component by the series connection of LED light-emitting diode.Simultaneously select different electric currents by many grades of brightness regulating switch, " strong, in, weak " that reach light-emitting diode changes, thereby replaces the light modulation of incandescent lamp bulb, and its electric energy converts the luminous energy overall process to and is low-power consumption.
The utility model has adopted such scheme only to manage cost and has slightly raise, but along with the raising of production efficiency, also can overcome, and the more important thing is and saved the energy, and the multiple glow color of LED tool, range of application is very wide.
Description of drawings: many grades of LED lamp dimmers of the utility model piano type are described in further detail below in conjunction with drawings and Examples.
