Embodiment

Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this Content disclosed by specification understands other advantages and effect of the present utility model easily.

As shown in Figure 1-2, a kind of advertising lamp of changeable colour, including connected LED Color-changing lamps body and LED Color-changing lamps electricity Road, LED discoloration circuit for lamp include power module, control color change module, LED array module.

Power module is including the decompression capacitor C2 being sequentially connected, the full-wave rectifying circuit that diode D2, D3, D4, D5 are formed, Voltage-regulator diode D6, voltage-regulator diode D6 are connected with filtered diode D1 and filter capacitor C1.

Control color change module includes 14 binary notation device CD4060, resistance R3, resistance R5, electric capacity C3, electric capacity C3 and Clock pulses among CD4060 output terminal of clock pulse Clockout2 connections, resistance R5 and electric capacity C3 with CD4060 inputs Hold Clockin connections.CD4060 power positive end VDD is connected with filter capacitor C1 positive pole, CD4060 numeration pulse output Q8, Q9, Q10 are connected with LED array module at end, CD4060 power supply negative terminal Vss ground connection, CD4060 the RESET input Reset is connected by resistance R2 with filter capacitor C1 positive pole.

LED array module includes switching diode D7, D8, D9, and switching diode D7, D8, D9 positive pole are defeated with reset Enter to hold Reset to connect, switching diode D7, D8, D9 negative pole are connected with numeration pulse output end Q8, Q9, Q10 respectively.

LED Color-changing lamps body includes three-primary color LED lamp group, and three primary colours are red, blueness, green, and red LED lamp set includes Current-limiting resistance R6 and the light emitting diodes of 4 series connection and be connected with numeration pulse output end Q8, it is electric that blue LED lamp group includes current limliting Resistance R7 and 4 series connection light emitting diode and with numeration pulse output end Q9 be connected, green LED lamp set include current-limiting resistance R8 with 4 series connection light emitting diodes and with numeration pulse output end Q10 be connected.

As the further optimization to the technical program, full-wave rectifying circuit and resistance R3 are connected to external power interface respectively P2 AC1 and AC2.LED array module is connected with single needle stand P1.Decompression capacitor C2 is parallel with resistance R4.

To be powered by power module, decompression capacitor C2, diode D2, D3, D4, D5 are formed operation principle of the present utility model Full-wave rectifying circuit and voltage-regulator diode D6 composition capacitor step-down circuit as AC/DC change-over circuits.Voltage stabilizing through 15V Power supply after diode D6 voltage stabilizings as LED array module, after filtered diode D1 and filter capacitor C1 filtering, about 14.5V voltage supplies 14 binary notation device CD4060 and the voltage of reset.The resistance R4 in parallel with decompression capacitor C2 exists After deenergization, the electric charge on decompression capacitor C2 discharges through resistance R4, prevents powered on lamp holder.

The characteristics of this power module, is, when the voltage of load is much smaller than 220V, (C is drop to electric current IL ≈ 69C in load Voltage capacitance, unit uF, IL unit are mA).For example, during C=0.47u F, the electric current about 32.4mA of load, and this are flowed through Individual electric current is more stable：In addition, this size of power is small, take up space small.

Control color change module is undertaken by 14 binary notation device CD4060, and clock pulse signal does not use in general to vibrate Device circuit, series resistor R3, the differential circuit that the 50Hz alternating voltages on resistance R3 form through resistance R5, electric capacity C3 form point Pulse connects with numeration pulse output end Q8, Q9, Q10 respectively as clock pulse signal, switching diode D7, D8, D9 negative pole Connect.When count pulse output end low level when, the LED light group of respective color is lit.50Hz cycle is 0.02s, Q8 week Phase is 5.12s, and Q9 cycle is 10.24s, and Q10 cycle is 20.48s.

Numeration pulse output end Q8 connects the negative pole of red LED lamp set, numeration pulse output end Q9 connects the negative of blue LED lamp group Pole, numeration pulse output end Q10 connect the negative pole of green LED lamp set, then are high level, numeration pulse in numeration pulse output end Q8 It is blue, green because the RESET input Reset is low level when output end Q9, numeration pulse output end Q10 are low level Color LED light group is bright, and green light is sent after colour mixture, and it is bright to become red, green LED lamp set after 2.56s, sends gold-tinted.

During to pulse output end Q8 to the 4th cycle of numeration, numeration pulse output end Q8, Q9, Q10 output is all high electricity Flat, then three-primary color LED lamp group is all gone out.To avoid occurring in colourshifting process such case, three switches are added in circuit Diode D7, D8, D9, and the RESET input Reset is connected to by resistance R2, it is firm occur numeration pulse output end Q8, Q9, When Q10 is high level, now occurring high level on the RESET input Reset, 14 binary notation device CD4060 are reset, It is all low level to make its pulse output end that respectively counts.

Once count pulse output end Q8, Q9, Q10 are low level, primary-color LED lamp group is all bright, light exists into white light After there is feux rouges, when feux rouges terminates, white light is immediately turned to, the RESET input Reset is immediately turned to low level, has skipped 2.56s Situation of turning off the light, this is the ingenious part of this circuit design.

Because the red LED of light emitting diode of 4 series connection, the tube voltage drop of green LED are different from the tube voltage drop of blue led And luminous intensity is different, and different current-limiting resistance R6, R7, R8 are provided with LED Color-changing lamp bodies, has on the one hand forced LED Electric current, also make luminosity matching more preferable in addition.Three-primary color LED lamp group is using the straw hat type that visual angle is big, brightness is high.Decompression electricity Container C2 is safer using pressure-resistant 400V's.

The changeable colour advertising lamp of the utility model design, changed colour circuit for lamp by connected LED Color-changing lamps body and LED, Powered by the power module of LED discoloration circuit for lamp, control color change module to control LED array module and LED Color-changing lamp bodies, it is real The changing color freely of existing advertising lamp, circuit structure is simple, and control performance is good, and power saving, cost is low, suitable for large-scale user on the market Promote the use of.

Above-mentioned embodiment, only illustrate technical concept and architectural feature of the present utility model, it is therefore intended that allow ripe Knowing the stakeholder of technique can implement according to this, but above content is not intended to limit the scope of protection of the utility model, every Any equivalent change or modification made according to Spirit Essence of the present utility model, all should fall into the scope of protection of the utility model Within.
