Detailed description of the invention

In conjunction with accompanying drawing, the utility model is described in further detail, sees accompanying drawing 1-2.

As shown in Figure 1-2, this utility model one low-power consumption all-colour LED module, including radiator 11, substrate 10 and full-color LED group 12, described radiator 11 is installed on the bottom of substrate 10, and described full-color LED lamp group 12 is installed on the top of substrate, institute Stating substrate 10 and be provided with energy-saving control device 13, described energy-saving control device 13 is provided with rectification circuit, and described rectification circuit is by rectification Bridge heap VD1-VD4 is constituted, and the DC output end of this rectifier bridge stack VD1-VD4 connects full-color LED lamp group, in all-colour LED lamp bead Two ends, are connected in parallel to a filter capacitor C3, at an ac input end of rectifier bridge stack VD1-VD4, are connected in series with one Individual bidirectional thyristor VT, is connected in parallel to a resistance capacitance phase-shift circuit, at resistance and electricity at the two ends of bidirectional thyristor VT That holds is connected in series a little between the trigger electrode of IGCT VT, connects and has a bilateral diode VD, by the heat radiation arranged Device, LED module uses for a long time when, improves LED module radiating effect, extends LED module service life, passes through The energy-saving control device arranged reduces the power consumption of LED module, relative energy-saving.

Wherein, VT is the bidirectional thyristor of BT136, and VD is the bilateral diode of DB3202, and L is 4mH ribbon core electricity Sense, C1 and C2 is 0.1uf calculus electric capacity, and C3 is 220uf electrochemical capacitor, and VD1-VD4 is IN4001's or IN4007 Commutation diode.

Concrete, the ac input end of described rectifier bridge stack VD1-VD4 is provided with LC filter circuit, at bidirectional thyristor It is connected between the outfan of VT and an ac input end of rectifier bridge stack VD1-VD4 and has inductance L, at rectifier bridge stack D1- Connect between two inputs of VD4 and have electric capacity C1.

In the present embodiment, described resistance capacitance phase-shift circuit is connected in series by potentiometer RP, resistance R1 and electric capacity C2 Constitute, be connected in series a little between the trigger electrode of IGCT VT at resistance R1 and electric capacity C2, connect bilateral diode VD。

As Fig. 2 shows, the operation principle of circuit is to provide one surely for rectifier bridge stack by the conducting of bidirectional thyristor VT Fixed alternating voltage, powers for LED lamp and makes it luminous, to realize potentiometer RP, the electricity that it uses as a ligthing paraphernalia Resistance R1, electric capacity C1 and bilateral diode VD constitutes the triggering circuit of IGCT VT, wherein potentiometer RP, resistance R1, electric capacity C2 forms RC phase-shift circuit, controls phase-shifting voltages by bilateral diode VD and controls IGCT VT conducting, and electric current passes through Inductance L and the high frequency filter of electric capacity C1 composition below provide a stable alternating current for rectifier bridge stack VD1-VD4 Pressure.By the rectification of VD1-VD4, become DC voltage through below and the electric capacity C3 that is connected on bridge heap make low frequency filtering after to LED lamp group is powered.Owing to the line footpath of inductance L is thick, the number of turn is few, and the capacity of electric capacity C1 is the least, so their impedance is the most not Can affect the brightness of lamp, but lamp group is again direct with rectifier bridge stack and connects, the shortest middle wire, line loss is the least. Thus the loss of power can be preferably minimized by this circuit, more electrical power is allowed to obtain the conversion of maximum by LED.

Wherein, RP is as adjustable resistance, for adjusting the alternating voltage controlling rectifier bridge stack input, to meet through whole After stream bridge heap rectification, the DC voltage of output is adapted to the needs of lamp group.When the voltage request of lamp group raises, it is possible to decrease RP Resistance realize.After product complete design is gone into operation, by lamp group required voltage, with fixed value resistance replace this potentiometer RP and Resistance R1, thus reduce production cost.
