Abstract
The utility model discloses an LED high-power and energy-efficient lamp, and comprises a lamp body and a lightening circuit made up of a plurality of LED luminous diodes positioned on the lamp body. The lightening circuit is composed of a plurality of groups of the lightening branches connected in series, and each group of lightening branches LED is composed of a plurality of shunt-wound LEDs. Because of adopting the groups connected in series and the shunt-wound groups of LEDs, the utility model not only enhances the supply power voltage of the lightening circuit and thus reduces to the current of the work circuit, but also increases the power through using a lot of LEDs, thereby improving the bright of the lamp. Moreover, the current in the shunt-wound branches where various luminous diodes arranged is very small; therefore, the power consumption of the circuit is so small that it can be skipped.
Description
Technical field
The utility model relates to a kind of electricity-saving lamp of making illuminator with the LED light emitting diode.
Background technology
Make at present the electricity-saving lamp of illuminator,, thereby be used widely as the illumination use of public places such as corridor lamp because the LED light emitting diode has low, the long service life of energy consumption with the LED light emitting diode.This class electricity-saving lamp normally is made up of control circuit and several LED light emitting diodes, and light emitting diode connects in mode in parallel or series connection usually.When light emitting diode connects with parallel way, because the monomer whose operating voltage is 3.2～3.5VDC, therefore so common power of electricity-saving lamp is less, otherwise the electric current of mains supply line is excessive, if cable causes the power attenuation on the circuit to increase than detailed rules and regulations, inconvenience in the use can be brought and increase thick cable line footpath, also cost can be increased simultaneously.When light emitting diode connects with series system, as the disclosed electricity-saving lamp of Chinese patent CN2708100Y, limited by supply voltage, the limited amount of light emitting diode, therefore such electricity-saving lamp power is still lower, generally have only several watts, the brightness of lamp is limited, can not need provide the place of big brightness to use as street lamp, advertising lamp etc.
Summary of the invention
The purpose of this utility model provides a kind of LED large power high efficiency electricity-saving lamp, can meet the needs of the higher place of lighting brightness and use.
The utility model is achieved in that it comprises lamp body and is fixed on the lighting circuit of being made up of several LED light emitting diodes on the lamp body, described lighting circuit is made up of the lighting sub loop of some groups of series connection, and every group of lighting sub loop light emitting diode is made up of several LED light emitting diodes in parallel.Owing to adopt many group series connection, every group of a plurality of LED light emitting diode parallel way, both can improve the supply voltage of lighting circuit, thereby reduce the electric current of operating circuit, can use a large amount of light emitting diodes to improve its power again, can improve the brightness of lamp, and the parallel branch electric current at each light emitting diode place is very little, thereby the circuit power consumption is very little, can ignore.
The accelerated luminescence diode is aging in order to prevent the source current fluctuation from causing overcurrent, also is provided with constant-current control circuit on the power circuit of lighting circuit.
The beneficial effects of the utility model are embodied in: 1, common LED parallel connection is to increase power, power can reach hundreds of watts, by connecting to improve operating voltage, reduce circuital current, reduce the circuit power consumption, operating voltage can be selected in 12～220V DC voltage scope as required, can be suitable as street lamp, advertising lamp use; 2, be provided with constant-current control circuit, can prevent the aging of light emitting diode, improve its service life; 3, circuit structure is simple.
