Description
Technical field
This utility model belongs to LED lamp technical field, specifically, relates to a kind of MCU and switchs switch light modulation device.
Background technology
Have the advantages such as life-span length, light efficiency height, energy-conserving and environment-protective due to LED lamp product, LED illumination is developed the most rapidly as lighting engineering of new generation.
Along with the development of intelligent control technology, intelligent lighting product constantly emerges in large numbers.Wherein, LED lamp is required for a driver.Driver uses the output of double-colored temperature at present, sectionaliser is arranged on input, then two independent driving power supplys are connected, when powering on, sectionaliser enters duty, respectively using two relays as the output of on-off control two-way, its operation principle is: when first powering on, first relay of sectionaliser engages, second circuit breaker disconnects, at this moment first via power supply energising output, then (power-off is once) is switched once, second relay of sectionaliser engages, first relay disconnects, at this moment the second road power supply energising output, switch once (power-off is once) again, two circuit breakers simultaneously engage with, at this moment two-way power supply is energized output together.
Above-mentioned type of drive there is also the defect that these are many, it is mainly reflected in: need to be used as segmentation at input with a sectionaliser, need to use two input powers, aforesaid way wiring is many and needs the screw using fixed segments device and two power supplys many, and relay life is short, operation action is many and relatively costly, can often go wrong, there is certain danger after long-time use.
In consideration of it, technical staff needs to develop a kind of MCU switchs switch light modulation device, reasonable in design, need not with sectionaliser, it is only necessary to a power supply, wiring is few and to have only to fix a power supply all right, the electrical switch life-span is high, and operation action is few and low cost, has good practicality and promotional value.
Summary of the invention
The technical problems to be solved in the utility model is to overcome drawbacks described above, a kind of MCU is provided to switch switch light modulation device, reasonable in design, need not with sectionaliser, it is only necessary to a power supply, wiring is few and to have only to fix a power supply all right, the electrical switch life-span is high, operation action is few and low cost, it is ensured that the safety of use and ensure the safety of staff, has good practicality and promotional value.
For solving the problems referred to above, this utility model be the technical scheme is that
MCU switchs switch light modulation device, it is characterised in that: described MCU switch switch light modulation device is arranged on a circuit board, described circuit board is provided with controller, is provided with power input simultaneously on circuit board, and power input connects voltage changing module；Described controller connects auxiliary power supply circuit, voltage changing module and two DC-DC converter, and a DC-DC converter connects a light source.
As the technical scheme of a kind of optimization, described controller is MCU.
Owing to have employed technique scheme, compared with prior art, this utility model is reasonable in design, need not with sectionaliser, it is only necessary to a power supply, wiring is few and to have only to fix a power supply all right, the electrical switch life-span is high, operation action is few and low cost, it is ensured that the safety of use and ensure the safety of staff, has good practicality and promotional value.
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of embodiment of this utility model.
Detailed description of the invention
Embodiment:
As it is shown in figure 1, MCU switchs switch light modulation device, described MCU switch switch light modulation device is arranged on a circuit board, described circuit board is provided with controller, is provided with power input simultaneously on circuit board, and power input connects voltage changing module；Described controller connects auxiliary power supply circuit, voltage changing module and two DC-DC converter, and a DC-DC converter connects a light source.
In the present embodiment, described controller is MCU.
The when of actually used, need to increase by a road auxiliary power supply circuit at power supply and power to mono-stable 3.3V of MCU, respectively MCU two-way output I/O mouth is received the two-way output control terminal on power supply.
nullTransformator outfan provides a winding to power to mono-stable 3.3V of MCU，From Transformer Winding, connect two electric resistance partial pressures to MCU as detection of power loss simultaneously，Two PWM output pins of MCU are coupled with on the DIM foot of two-way DC-DC，Operation principle is，When input switch is shut，Power supply normally works，Transformator supply MCU3.3V voltage，MCU PWM 1 exports high level，Control the output of first via DC-DC，When input switch is powered-down once，Transformator output can follow voltage to decline once，Voltage on winding also can and then decline，At this moment MCU detect that power down is once，PWM 1I/O mouth will be output as low level，And PWM 2I/O mouth can export high level signal，Control the DC-DC output on the second tunnel，Again powered-down for input switch once，Transformator output can follow voltage to decline once，Voltage on winding also can and then decline，At this moment MCU detect that power down is once，PWM 1/2I/O mouth will simultaneously output HIGH voltage，The first via the second road DC-DC exports simultaneously.
This utility model is reasonable in design, it is not necessary to sectionaliser, it is only necessary to a power supply, wiring is few and to have only to fix a power supply all right, and the electrical switch life-span is high, and operation action is few and low cost, ensure the safety used and the safety ensureing staff, there is good practicality and promotional value.
This utility model is not limited to above-mentioned preferred implementation, and anyone should learn the structure change made under enlightenment of the present utility model, every have with this utility model same or like as technical scheme, belong to protection domain of the present utility model.
