Description

Exchange thumb lamp controller

Technical field

The utility model belongs to LED control field, relates to a kind of interchange thumb lamp controller.

Background technology

At present, there is a kind of card insert type LED controller on the market, its shell is provided with SD draw-in groove, as long as the SD card that program is housed is inserted in this SD draw-in groove, the singlechip chip of controller inside can read the program in SD card, and under the triggering of outer button, realize the function switching LED lighting mode.

But, because this SD draw-in groove exists the possibility of water inlet, need to take certain seal approach, this complexity just making the structural design at SD draw-in groove place become, and, at present conventional hermetically-sealed construction is not long for useful life, there will be the decline of sealing property after repeatedly plug SD card, can not in the effect reaching waterproof truly.

In addition, current LED is in order to realize the switching of different colours, general in the LED (RGB) of same lampshade built with three kinds of colors, the display of shades of colour is reached according to the various combination of the lamp of three kinds of colors, and a whole cluster of lamps, ornamental is formed by connecting by many lampshade wires, but, product is in the market all the LED controlled separately by controller in each lampshade, this just makes the complex structure on circuit, required wire is also longer, cause cost higher, and, such mode also cannot grow with each passing hour in the realizing of control effects, meet current demand.

Therefore, for above problem, be necessary to propose a kind of new solution.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of exchanges thumb lamp controller, have employed the design of internal memory, reaches the object of waterproof; In addition, adopt special LED drive chip to drive RGB tri coloured lantern, greatly simplify line construction, reduce cost, enhance control effects.

For achieving the above object, the utility model provides following technical scheme: a kind of interchange thumb lamp controller, comprises, AC/DC transducer; Governor circuit, there is a control chip and a memory, this memory writes corresponding program by the mode of burning program, and this control chip can read the program in this memory, and controls button to export a data-signal and a clock signal in response to one; Drive circuit, be made up of the cascade of polylith LED drive chip, described LED drive chip comprises RGB output pin, signal input pin, clock input pin, signal output pin, clock output pin, wherein, RGB output pin couples RGB tri coloured lantern respectively, the signal input pin of first piece of LED drive chip be coupled to this data-signal, clock input pin is coupled to this clock signal, and the signal input pin of all the other LED drive chip and clock input pin are coupled to signal output pin and the clock output pin of upper level LED drive chip all successively; This drive circuit in response to data-signal and clock signal with the operating state of control RGB tri coloured lantern; This memory and governor circuit are together packaged in shell; The operating voltage of this drive circuit and governor circuit provides by this AC/DC transducer.

Further, described control chip is single-chip microcomputer.

Further, described LED drive chip is triple channel LED constant current driving chip.

Further, described interchange thumb lamp controller provides galvanic current by a power supply adaptor.

Compared with prior art, the utility model has the advantages that:

By by this memory built-in in shell, avoid the waterproof defect of SD draw-in groove in prior art.In addition, the utility model make use of the drive circuit that is made up of polylith triple channel LED constant current driving chip to drive RGB tri coloured lantern, circuit structure is simplified, reduce cost, meanwhile, this triple channel LED constant current driving chip, by RGB output pin control RGB tri coloured lantern respectively, can realize the light on and off controlling separately a kind of LED of color, more reasonable in control mode, thus demand in the market can be met.

Embodiment

Referring to figs. 1 through Fig. 5, the utility model embodiment is described further.

A kind of interchange thumb lamp controller, comprises, AC/DC transducer; For alternating current is converted to direct current; Governor circuit, there is a control chip and a memory, this memory writes corresponding program by the mode of burning program, its model is CAT25040SI-TE13, this control chip can read the program in this memory, and controls button to export a data-signal and a clock signal in response to one; Drive circuit, be made up of the cascade of polylith LED drive chip, described LED drive chip comprises RGB output pin, signal input pin, clock input pin, signal output pin, clock output pin, wherein, RGB output pin couples RGB tri coloured lantern respectively, the signal input pin of first piece of LED drive chip be coupled to this data-signal, clock input pin is coupled to this clock signal, and the signal input pin of all the other LED drive chip and clock input pin are coupled to signal output pin and the clock output pin of upper level LED drive chip all successively; This drive circuit in response to data-signal and clock signal with the operating state of control RGB tri coloured lantern; This memory and governor circuit are together packaged in shell;

The operating voltage of this drive circuit and governor circuit provides by this AC/DC transducer.Therefore, the present embodiment by memory 110 is built in governor circuit 100, to be wholely closed in shell 400, thus avoids the defect of SD draw-in groove water inlet in prior art.In addition, this drive circuit 200 is formed by multiple LED drive chip (IC1 ~ ICn) cascade, the data-signal data input pin of first piece of LED drive chip (being IC1 in figure) is only needed to be connected with control chip, the signal input pin DI of all the other LED drive chip (IC2 ~ ICn) is coupled to the signal output pin DO of upper level LED drive chip all successively, like this, just the wiring trouble and Cost Problems that cause because the LED in each independent lampshade 600 is directly connected with control circuit in prior art is avoided.

In the present embodiment, control chip 220 is single-chip microcomputer.Its model is AT89C52.

LED drive chip (IC1 ~ ICn) is triple channel LED constant current driving chip.Its model is D705,

In addition, as can see from Figure 4, the interchange thumb lamp controller that the utility model provides adopts external power supply adapter 400 to provide stable 5V direct current.Relative to the LED controller by on-chip power, its advantage prevents single shell 400 volume excessive, and after using external power supply adaptor 400, directly cannot obtain galvanic occasion at some will be more convenient.Meanwhile, because power supply caloric value in the process used is comparatively large, if adopt built-in design, the heat that power supply can be made to produce impacts whole circuit.In addition, as can see from Figure 4, power supply adaptor 400 is connected with the circuit of electric wire with shell 500 inside, so, the length of electric wire on increase power supply adaptor 400 that can be suitable, make people when using controller, can be farther from civil power (220V) socket, avoid electric wire too short and need the situation of extra insert row.

Above, functional effect described by the utility model is based upon in the structural design of circuit, major way is by program-carried built-in chip type and have employed above-mentioned LED drive chip to drive RGB tri coloured lantern, and program does not belong to the technical solution of the utility model, and the technical solution of the utility model is not dependence program yet implements.
