Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
In Fig. 1, bridge rectifier is made up of diode D1, D2, D3, D4, and light adjusting circuit is made up of controllable silicon, R3, R5, potentiometer R4.The end of high-power resistance R1 exchanges with power supply 220V and links to each other, and an end links to each other with bridge rectifier input D1, D2; The end of the 1 small resistor R2 that beats up exchanges with power supply 220V and links to each other, and an end links to each other with bridge rectifier input D3, D4; The superbright light-emitting diode positive pole of series connection links to each other with anodal D2, the D3 of bridge rectifier output, and negative pole links to each other with negative pole D1, the D4 of bridge rectifier output; Silicon controlled A end links to each other with output D2, the D3 of bridge rectifier in the light adjusting circuit, the K end links to each other with D1, the D4 of bridge rectifier output, the G end links to each other with a end of R4, the two ends of R5 link to each other with silicon controlled G, K end respectively, the end of R3 links to each other with silicon controlled A end, the other end links to each other with the c end of R4, and a of R4, b end links to each other.
Described superbright light-emitting diode sends stronger light to play illuminating effect, described high-power resistance R1 is in order to current limliting, the 1 small resistor R2 that beats up is used as insurance, make the superbright light-emitting diode send the light that does not glimmer continuously with bridge rectifier for the superbright light-emitting diode provides DC power supply, flow through of the brightness of the electric current of superbright light-emitting diode with the light adjusting circuit adjusting with control superbright light-emitting diode.
Circuit except that the superbright light-emitting diode can concentrate in the etui, all superbright light-emitting diodes can be put according to different illumination occasion design diverse locations, the distance of superbright light-emitting diode and other circuit can be selected arbitrarily, if be the superbright light-emitting diode on the roof, design has the etui of switch can be first-class at the wall that is convenient to open and close.This design can all replace switch, lamp holder, the bulb of original old-fashioned illuminating lamp.Can be one with all circuit design except that switch S perhaps, can replace the lamp holder and the bulb of old-fashioned illuminating lamp like this, utilize original switch to control, save trouble from new route.
Because single superbright light-emitting diode issued light is not very strong, be similar to the optically focused of present LED flashlight, reflective principle so in the design of electricity-saving lamp of the present invention, utilize, will the brightness of electricity-saving lamp of the present invention be strengthened greatly.
The optimum number of the superbright light-emitting diode of connecting behind each bridge rectifier is 1～66, during unnecessary 66 of superbright light-emitting diode, can adopt identical circuit to light other superbright light-emitting diode, the brightness of superbright light-emitting diode is by resistance R 1, the decision of resistance that R3, R4, R5 got; The light that the many more integral body of superbright light-emitting diode are sent is just strong more, the power that how much influences entire circuit hardly of superbright light-emitting diode in an independent circuit.Mainly by the R1 decision, the value of R1 is 1K～200K to the power of entire circuit.
The selection of R3, R5 should make when the resistance of potentiometer R4 hour, the electric current that flows through the superbright light-emitting diode is required minimum value.If bulb does not need light modulation, light adjusting circuit can save.
Superbright light-emitting diode in this circuit adopts series connection, wherein any one other superbright light-emitting diode of superbright light-emitting diode punch through damage still can operate as normal, because the superbright light-emitting diode is equivalent to a lead after puncturing, entire circuit remains connection.
What play a role in lighting in this circuit is the superbright light-emitting diode, but the consumed power of entire circuit is not the superbright light-emitting diode, even the energy consumption of superbright light-emitting diode can ignore and not remember, because the conducting of superbright light-emitting diode is equivalent to lead consumed energy not basically after luminous.Energy consumption almost concentrates on the high-power resistance R1 in the entire circuit.
The operation principle of light adjusting circuit: when the resistance maximum of potentiometer R4 contact b R4 when a holds, controllable silicon G terminal voltage minimum, the conducting degree is minimum, i1 divide the electric current minimum, i2 divide the electric current maximum, the superbright light-emitting diode is the brightest.When the contact of R4 b raises from a controllable silicon G terminal voltage when c slides, the conducting degree raises, i1 divide electric current increase, i2 divide electric current reduce the light deepening that the superbright light-emitting diode sends.
Electricity-saving lamp of the present invention compared with prior art has following advantage:
(1) energy-conservation, power is little, only is 1～2 watt
(2) life-span long, calculate by every per day work 5 hours, the life-span can reach more than 10 years.
(3) adopt direct current supply, the light that sends does not have frequency scintillation, does not injure eyes.
(4) not fragile, be convenient to maintenance.
(5) for the user, use pair electricity charge, because kilowatt-hour meter will surpass in load usually Just can rotate under the condition of 5W.
