Abstract
The utility model discloses an LED lamp with a dual drive power supply. The LED lamp comprises two constant current and constant voltage power supply drive modules, an AC-DC power supply rectifying module, an MCU intelligent control module and a light-emitting LED lamp bead module group. The output ends of the two constant current and constant voltage power supply drive modules are simultaneously connected with the light-emitting LED lamp bead module group. The AC-DC power supply rectifying module is controlled by the MCU intelligent control module and electrically communicated with one of the two constant current and constant voltage power supply drive modules in an alternating manner to drive the LED lamp bead module group to give out light. According to the LED lamp with the dual drive power supply, two power supply drive modules are applied, and the MCU intelligent control module is utilized to control the two power supply drive modules to work in the alternating manner so that the service life and reliability of the whole lamp are effectively enhanced.
Description
Technical field
The utility model relates to the LED lighting technical field, relates in particular to the LED light fixture of two driving powers that a kind of simple in structure, bulk life time promotes.
Background technology
As shown in Figure 1, existing LED daylight generally is comprised of LED lamp pearl module and a constant current constant voltage driving power module, described AC turns the DC current rectification module and accepts 220V interchange input, after turning DC power rectifier module, AC becomes direct current, under the effect of driving power module, described LED lamp pearl module is accepted the input of constant current constant voltage direct current, and continues luminous.Existing LED fluorescent lamp bulk life time is mainly the impact that is subjected to the electric power driving module life-span, owing to having used jumbo electrochemical capacitor in power module, electrochemical capacitor is subjected to ambient temperature again and affects the life-span, cause the integral LED fluorescent lifetime low for this reason, make its working life limited time, general work 20000 hours, even use high-quality electrochemical capacitor life still can not meet the life requirements of some environment such as garage etc.
The utility model content
The purpose of this utility model is that the LED light fixture of two driving powers of a kind of simple in structure, good stability, long service life is provided for the deficiencies in the prior art.
to achieve these goals, the technical scheme that the utility model provides is: the LED light fixture that a kind of pair of driving power is provided, comprise two constant voltage supply driver modules, AC turns DC power rectifier module, MCU intelligent control module and light emitting LED lamp pearl module, the output of described two constant voltage supply driver modules is connected to described light emitting LED lamp pearl module simultaneously, the output that described AC turns DC power rectifier module is connected to the input of described two constant voltage supply driver modules simultaneously, described MCU intelligent control module is connected to described two constant voltage supply driver modules simultaneously, the input of described MCU intelligent control module is also connected to described AC and turns the output of DC power rectifier module.
Described AC turns the control of DC power rectifier module through the MCU intelligent control module, and synchronization only one of them constant voltage supply driver module of electric connection is luminous for driving LED lamp group module.
Described MCU intelligent control module is a single-chip microcomputer.
Compared with prior art, the LED light fixture of described in the utility model pair of driving power, use two groups of electric power driving modules, and use MCU intelligent control module, two groups of electric power driving module alternations of Based Intelligent Control, the life-span of complete machine is doubled at least, to meet the requirement of some special screnes such as garage to the LED light fixture high life, in addition, when certain electric power driving module accidental damage, described MCU control module can also intelligence be fixed another electric power driving module that does not damage of use, thereby has improved the reliability of integral LED light fixture.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Description of drawings
Fig. 1 is the typical circuit module frame chart of current existing LED light fixture.
Fig. 2 is the circuit module block diagram of an embodiment of the LED light fixture of the two driving powers of the utility model.
Embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, in accompanying drawing, similar element numbers represents similar element.
as shown in Figure 2, the LED light fixture of a kind of pair of driving power that the utility model provides, comprise two constant voltage supply driver modules, AC turns DC power rectifier module, MCU intelligent control module and light emitting LED lamp pearl module, the output of described two constant voltage supply driver modules is connected to described light emitting LED lamp pearl module simultaneously, the output that described AC turns DC power rectifier module is connected to the input of described two constant voltage supply driver modules simultaneously, described MCU intelligent control module is connected to described two constant voltage supply driver modules simultaneously, the input of described MCU intelligent control module is also connected to described AC and turns the output of DC power rectifier module.
Described MCU intelligent control module is a single-chip microcomputer, the MCU intelligent control module is according to preset value, one of them constant voltage supply driver module is used in one after the other, guarantee that described AC turns the control of DC power rectifier module through the MCU intelligent control module, synchronization only one of them constant voltage supply driver module of electric connection is luminous for driving LED lamp group module.
During actual the use, the current flowing situation of whole LED light fixture is: the described AC of 220V alternating voltage input turns DC power rectifier module, output dc voltage, supply with the power demands of MCU single-chip microcomputer, described MCU intelligence handover module is according to one of them constant voltage supply driver module of preset value rotation alternate selection, control described AC and turn DC power rectifier module and be communicated with this constant voltage supply driver module, the input that the output voltage of described constant voltage supply driver module is input to LED lamp pearl module drives the luminous work of described LED lamp pearl.
As seen from the above, the LED light fixture of described in the utility model pair of driving power, use two groups of electric power driving modules, and use MCU intelligent control module, two groups of electric power driving module alternations of Based Intelligent Control, double the life-span of complete machine at least, when certain electric power driving module accidental damage, described MCU control module can also intelligence be fixed another unspoiled electric power driving module of use, thereby has improved the reliability of integral LED light fixture.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore according to the utility model claim, doing, still belong to the scope that the utility model is contained.
