Abstract
The utility model discloses a novel light balance LED lamp which comprises two sets of LED lamp beads connected in parallel. One set of LED lamp beads are sequentially connected with a constant current circuit and a rectifying circuit and then are connected with a power source. The other set of LED lamp beads are sequentially connected with a rectifying circuit and a voltage decreasing circuit and then are connected with a power source. According to the novel light balance LED lamp, the power sources and light sources are combined, and the two simple power sources respectively drive a set of light sources, so that a combined light source lamp is formed, and the problems that light is stroboscopic, fluctuates and is dark due to the fact that a single power source is adopted are solved or relieved. The novel light balance LED lamp is suitable for popularization.
Description
Technical field
The utility model relates to a kind of LED lamp, particularly a kind of novel photo-equilibrium LED lamp.
Background technology
LED device is to the requirement of driving power near harshness, and LED lamp pearl, unlike common incandescent lamp bulb, can directly connect the electric main of 220V.LED lamp pearl is the low voltage drive of about 3 volts, must design complicated translation circuit, and the LED lamp of different purposes, be equipped with different power supply adaptors.Present LED lamp is all luminous by constant current DC control, direct current quality is better, luminous just more stable, effect is also better, that is to say, power supply is also the key element that has determined light source luminescent effect, but low price power supply adopts the power supply mode of single linear power supply mostly now, easy like this cause LED lamp with mains ripple the dark problem such as bright of stroboscopic, fluctuation, and the electric capacity life problems of high quality power supply, and the problem such as with high costs also makes the Difficulty of LED lamp.
Utility model content
The purpose of this utility model is just to provide a kind of light stable output, and cost is lower, the novel photo-equilibrium LED lamp of long service life.
To achieve these goals, the technical solution adopted in the utility model is such: novel photo-equilibrium LED lamp of the present utility model, comprise the LED lamp pearl of two groups of parallel connections, and wherein one group of LED lamp pearl is connected with power supply with after constant-current circuit and rectification circuit are connected successively; Another is connected with power supply after organizing LED lamp pearl and rectification circuit and reduction voltage circuit being connected successively.
As preferably, described constant-current circuit comprises two constant current chip IC, after two constant current chip IC parallel connections, is connected with rectification circuit and LED lamp pearl.
As preferably, described reduction voltage circuit comprises a resistance and an electric capacity, resistance with after Capacitance parallel connection, be connected with power supply and rectification circuit.
Compared with prior art, the utility model has the advantage of: the utility model adopts the method that power supply and light source are combined, be with respectively one group of light source with 2 simple power supplys, form a combined light source light fixture with this, solve or alleviate the dark problem such as bright of stroboscopic, fluctuation that single (no electrolytic capacitor) power supply causes.The utility model utilizes current regulator diode band portion lamp pearl and resistance-capacitance depressurization lamp pearl cross arrangement, utilizes the peak phase of electric current to move mutually to make up luminous, forms Integral luminous stable, solves the defect of single power supply mode; Capacitance-resistance mode is simple but cannot push away high-power, current regulator diode scheme can push away relatively high power but stroboscopic is serious, they are just in time because the phase difference that electric capacity forms makes up, power makes up, making Integral luminous stable, is an integrated light source in outside, and cost advantage is also obvious, are all low price power source designs, promotion LED lamp is entered to huge numbers of families positive role.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 is electric current output waveform figure of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1 and Fig. 2, novel photo-equilibrium LED lamp of the present utility model, comprises the LED lamp pearl of two groups of parallel connections, and wherein one group of LED lamp pearl is connected with power supply with after constant-current circuit and rectification circuit are connected successively; Another is connected with power supply after organizing LED lamp pearl and rectification circuit and reduction voltage circuit being connected successively, described constant-current circuit comprises two constant current chip IC, after two constant current chip IC parallel connections, be connected with rectification circuit and LED lamp pearl, described reduction voltage circuit comprises a resistance and an electric capacity, resistance with after Capacitance parallel connection, be connected with power supply and rectification circuit.
Power supply of the present utility model comprises two parts, the current regulator diode mode of the capacitance-resistance mode of reduction voltage circuit and rectification circuit composition and rectification circuit and constant-current circuit composition, current regulator diode band portion lamp pearl and resistance-capacitance depressurization band portion lamp pearl are carried out to cross arrangement, from circuit theory diagrams, the peak value of electric current can produce phase shift and mutually make up; So, when current regulator diode lamp pearl is dimmed, resistance-capacitance depressurization lamp pearl can be the brightest, and such arranges, can mutually make up luminous, thereby reach the stable effect of Integral luminous, solve the defect of single power supply mode; Capacitance-resistance mode is simple but cannot push away high-power, current regulator diode scheme can raise forces down electric current, but light and shade fluctuation is serious, and the combination of capacitance-resistance mode and current regulator diode scheme, just can form phase difference makes up, power makes up, and reaches the stable effect of Integral luminous, is an integrated light source in outside.The utility model has cost advantage simultaneously, is low price power source design, and promotion LED lamp is entered to huge numbers of families positive role.
