Abstract
The utility model relates to a wide power range adjustable LED lamp, comprising a driving apparatus, a dimmer, a plurality of modules and a plurality of LED lamp beads, wherein the driving apparatus is connected with the plurality of modules respectively through signal lines, the dimmer is connected with the plurality of modules through the signal lines respectively, the modules are connected with the LED lamp beads through the signal lines, and the modules are connected with each other through the signal lines. The wide power range adjustable LED lamp has the beneficial effects that a power switch is employed to convert a 220 V alternating current into an electric parameter enabling the single-chip microcomputer of the LED lamp and the LED dimmer to normally work, then the single-chip microcomputer receives the level signal of a potentiometer, then outputs a corresponding PWM signal to control a constant current module to work, and outputs a PWM constant current signal, and the PWM 256-order smooth dimming output is high in precision and efficiency, thereby reducing frequency flickering, and prolonging the service life of the LED.
Description
Technical field
The utility model relates to a kind of wide adjustable power joint LED lamp, relates in particular to a kind of new forms of energy and energy-efficient wide adjustable power joint LED lamp.
Background technology
The reasonable utilization of social resources has now highlighted important.The LED light fixture has advantages such as energy-saving and environmental protection, in the main trend that develops into of light fixture industry.And existing nowadays most LED lamp does not have the function of regulating brightness, and the LED lamp that can regulate brightness is easier to bad again.How high accuracy, regulate the brightness of LED lamp expeditiously, and increase the useful life of LED lamp, this is the problem that a lot of producers need solve.
Wide adjustable power joint LED lamp is that the following dual mode of utilization is regulated on the basis of LED light fixture:
1. after mains switch becomes the alternating current of 220v into the electrical quantity of the monolithic operate as normal that can make LED lamp and LED dimmer; After single-chip microcomputer is accepted to detect the level signal of potentiometer then; Export corresponding pwm signal and control constant flow module work, output PWM constant current signal amplifies the metal-oxide-semiconductor of the signal of input through the expander the inside then synchronously; Insert amplifying signal on the LED light fixture again; (fluorescent tube quantity can be infinite) regulated large-scale power thereby controlled, and also controlled the brightness of LED lamp.(attaching the technological development route)
2. after mains switch becomes the alternating current of 220V into the electrical quantity of the unit sheet operate as normal that can make LED light fixture and LED dimmer; After single-chip microcomputer is accepted to detect the level signal of potentiometer then, export corresponding pwm signal and control constant flow module work, output PWM constant current signal; Insert a corresponding module to the signal of input then; Module is amplified signal through concussion, inserts amplifying signal on the LED light fixture (fluorescent tube quantity can infinitely increase) again; Regulate large-scale power thereby controlled, also controlled the brightness of LED lamp.
The utility model content
The utility model technical problem to be solved is to provide a kind of ability high accuracy, high efficiency to regulate the wide adjustable power joint LED lamp of brightness and long service life.
A kind of wide adjustable power joint LED lamp; Comprise drive unit, dimmer, plurality of modules and some LED lamp pearls; Described drive unit is connected with module through holding wire; Dimmer is connected with plurality of modules respectively through holding wire, and module is connected with LED lamp pearl through holding wire, connects through holding wire between the module.
Preferably, the holding wire between the said module is 2.
Preferably, the holding wire that is connected with LED lamp pearl of said module is 2.
The beneficial effect of the utility model is: after the employs power switch becomes the alternating current of 220V into the electrical quantity of the unit sheet operate as normal that can make LED light fixture and LED dimmer; After single-chip microcomputer is accepted to detect the level signal of potentiometer then, export corresponding pwm signal and control constant flow module work, output PWM constant current signal; The level and smooth light modulation output of PWM256 level; High accuracy, high efficiency have promptly reduced stroboscopic, have prolonged the useful life of LED again.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described further, but the protection range of the utility model is not limited to this.
Embodiment 1
As shown in Figure 1; A kind of wide adjustable power joint LED lamp; Comprise drive unit 1, dimmer 2, plurality of modules 3 and some LED lamp pearls 4, described drive unit 1 is connected with plurality of modules 3 respectively through holding wire, and dimmer 2 is connected with plurality of modules 3 respectively through holding wire; Module 3 is connected with LED lamp pearl 4 through holding wire, connects through holding wire between the module 3.
As shown in Figure 1, after a kind of wide adjustable power joint LED lamp, employs power switch become the alternating current of 220V into the electrical quantity of the unit sheet operate as normal that can make LED light fixture and LED dimmer 2; After single-chip microcomputer is accepted to detect the level signal of potentiometer then, export corresponding pwm signal and control constant flow module work, output PWM constant current signal; Insert a corresponding module to the signal of input then, module is amplified signal through concussion, inserts amplifying signal on the LED light fixture again; (fluorescent tube quantity can infinitely increase) regulated large-scale power thereby controlled, can regulated at will brightness; Can accomplish not stroboscopic, prolong the useful life of LED lamp.Thereby effectively utilized resource, the real purpose that has reached energy-saving and emission-reduction has been protected the LED lamp effectively.
