Description
Technical field
The utility model relates to a kind of light-emitting device, particularly a kind of moulding lamp.
Background technology
Lamp decoration is used as decorates extensive use, particularly in various festival celebrations with corresponding representative as decoration, to increase happy atmosphere.Ice flower model lamp promptly is by moulding lamp water being freezed, can forming the various ice lantern arts work of ice cover.The moulding lamp generally all is to be support with three-dimensional contouring lamp decoration model in the prior art, and colligation lamp string on support then is nested with the sleeve pipe of a surperficial concave-convex surface again outside the lamp string, can make light continuous like this, and have waterproof effect.Moulding lamp of the prior art does not generally all have embedded control chip, the demonstration of lamp string changes single, and the driving control chip of lamp decoration is generally all formed a transmission channel by four circuits and is come transmission of control signals in the prior art, circuit generally has two input heads when connecting, two deliveries, each one of power connection and Signal connector, joint can cause the fault rate height too much, reliability reduces, and also makes the complex circuitization of moulding lamp simultaneously; The lamp string is nested with a sleeve pipe outward, though can play good waterproof effect, has also increased the volume of lamp string simultaneously, the heaviness that the lamp string is become.
The utility model content
The utility model is in order to solve deficiency of the prior art, and the ice flower model lamp of a kind of simple in structure, stable signal transmission, easy to maintenance and tool waterproof effect is provided especially.
The technical solution of the utility model is:
A kind of ice flower model lamp comprises model bracket, colligation lamp body and the power line on model bracket, it is characterized in that: described lamp body comprises that some display units are electrically connected the lamp string that forms by flexible cord; Each display unit comprises pcb board, is arranged on single wire transmission drive control chip and LED light emitting diode on the pcb board; Described single wire transmission drive control chip directly drives the described LED lumination of light emitting diode of control by a signal controlling circuit input control signal.
Described single wire transmission drive control chip is the single wire transmission drive control chip that carries PWM.
Described single wire transmission drive control chip has the deixis of reporting an error, when chip makes a mistake, and chip output error index signal.
Described pcb board and the single wire transmission drive control chip that is arranged on the pcb board are encapsulated in the described LED light emitting diode.
Described display unit adopts the waterproof plastic cement to seal admittedly.
Described LED light emitting diode is a Piranha LED light emitting diode.
Described LED light emitting diode comprises and contains more than one tube core at least.
Described tube core is a kind of or any combination in red light emitting diodes tube core, green LED tube core and the blue LED tube core.
Described pcb board is double-deck pcb board, described LED luminescence unit is arranged on the front surface of pcb board, described single wire transmission drive control chip is arranged on the rear surface of pcb board, and described single wire transmission drive control chip passes between pcb board and the described LED luminescence unit and is electrically connected.
As can be seen from the above technical solutions, the utlity model has following beneficial effect, adopted single wire transmission drive control chip, the signal controlling circuit has only one, and joint is an one-in-and-one-out, and connector quantity is few, the reliability height; Single wire transmission drive control chip reduces greatly than traditional driving control chip volume, and connection line is simple, makes pcb board can be designed into minimum, and display unit also can be designed into minimum, the very small volume and less weight of lamp string.
Description of drawings
Fig. 1 is a schematic appearance of the present utility model;
Fig. 2 is the structural representation of the utility model lamp body;
Fig. 3 is the utility model pcb board circuit diagram.
The specific embodiment
See Fig. 1, model bracket of the present invention is designed to the deer shape, can be designed to the shape of other animals or article, lamp body 2 and the power line 3 of colligation on model bracket, and lamp body 2 is by finishing to be with 4 colligations on model bracket 1.
See Fig. 2, lamp body 2 is electrically connected the lamp string that forms by some display units 5 by circuit 9.Display unit 5 is made up of pcb board 7, the LED light emitting diode 6 and the single wire transmission drive control chip 8 that are arranged on the pcb board, and pcb board 7 and the single wire transmission drive control chip 8 that is arranged on the pcb board 7 are encapsulated in the described LED light emitting diode 6; LED light emitting diode 6 is a Piranha LED light emitting diode, and lighting angle is big, light is even and brightness is high, and Piranha is the packaged type that exists under a kind of prior art, repeats no more here; LED light emitting diode 6 comprises at least more than one tube core, and tube core can comprise a kind of in red light emitting diodes tube core, green LED tube core and the blue LED tube core as required, perhaps is any combination of these three kinds of primary colours tube cores; Single wire transmission drive control chip 8 is for carrying PWM (Pulse width modulation, pulsewidth modulation, a kind of analog signal level is carried out digitally coded method) single wire transmission drive control chip, signal all can be from encoding and decoding through every grade of chip, and stable signal transmission and cascade signal are undamped; Pcb board 7 adopts double-deck pcb board, LED light emitting diode 6 is arranged on pcb board 7 front surfaces, single wire transmission drive control chip 8 is arranged on pcb board 7 rear surfaces, single wire transmission drive control chip 8 passes pcb board 7 and is electrically connected with the LED light emitting diode, this set not only makes the lamp string specious, can also reduce laterally taking up room of display unit.Circuit 9 comprises power line and signal control line, and circuit 9 is made into flexible cord by the outer parcel of waterproof insulation.Display unit 5 seals admittedly by the waterproof plastic cement, can make lamp string good waterproof effect.
See Fig. 3, pcb board 6 is provided with a positive source circuit 31, is connected with LED light emitting diode 6; A power cathode circuit 32 is connected with single wire transmission drive control chip 8; LED light emitting diode 6 comprises red light emitting diodes tube core 63, green LED tube core 62 and blue LED tube core 61, connects with R1, R2, R3 respectively; Single wire transmission drive control chip 8 is by signal controlling circuit 10 input control signals, and it is luminous directly to drive control LED light emitting diode 6; Be provided with the R4 that LED reports an error indicator lamp 64 and connects with indicator lamp 64 between described single wire transmission drive control chip 8 and a power cathode circuit 32, described single wire transmission drive control chip 8 has the deixis of reporting an error.When single wire transmission drive control chip 8 makes a mistake, single wire transmission drive control chip 8 output error index signals, report an error indicator lamp 64 received signals and reporting an error of LED report an error by indicator lamp 64, can know the position of making a mistake very soon, make easy to maintenance.Connected in series between the single wire transmission drive control chip 8 by positive source circuit 31, a power cathode circuit 32 and a signal controlling circuit 10.
