Description
This case is that application number is 200820112620.4, and the applying date is on April 21st, 2008, and denomination of invention is divided an application for the patent application of " LED light lamp and lamp string of synchronous light-emitting diode ".
Technical field
The utility model relates to light-emitting device, refers to a kind of lamp string of synchronous light-emitting diode especially.
Background technology
The application of lamp string is all very wide all the time, Christmans light string for example, the Landscape Lamp string, building lamp string etc., along with the progress of light emitting diode (LED) manufacturing process and price get over cheap, it also is a kind of new trend that LED is applied to the lamp string, but because LED is applicable to dc source, the lamp string then is the environment that is applied in AC power, how LED is applied to the lamp string, and more existing products see the market.But how reaching synchronous variation and then being one has obstacle to overcome.The utility model has been done a deep research at this problem, and has obtained concrete results, so propose patent application.
Present LED lamp string is then just like Fig. 1, Fig. 2 and prior art shown in Figure 3, and wherein each light emitting module is represented one group of RGB three-color LED light group 2.According to prior art, least desirable with technology shown in Figure 1, make all LED lamp groups 2 be all parallel connection because of adopting the DC parallel formula, so current sinking is big, that is to say that its power supply changeover device 1 can supply big electric current in order to want, very difficult or say that cost is higher, or the LED lamp group 2 of saying the energy parallel connection is limited.

Specific embodiment according to LED light lamp 10 shown in Figure 14, series connection pattern lamp string and pattern lamp string in parallel shown in Figure 15 B shown in Figure 15 A, lamp string of synchronous light-emitting diode comprises a plurality of LED light lamps 10, each LED light lamp 10 is as Figure 13 and shown in Figure 14, wherein a plurality of LED light lamps 10 are connected in series each other, and during the superior and the subordinate's LED light lamp 10 serial connections, the pin DO of upper level LED light lamp 10 is connected to the pin DI of next stage LED light lamp 10.Among this embodiment, provide dc source to the power supply changeover device 20 of lamp string of synchronous light-emitting diode to have data-handling capacity, can be by holding wire DO output order data to the input pin DI of first LED light lamp 10 color change order or flicker form with the control lamp string of synchronous light-emitting diode.
This power supply changeover device 20 can a built-in microprocessor or data processor and memory, stores form or effect that the lamp string will be showed, as the race lamp or make wild with joy or effect such as chase, even can show special pattern etc.Power supply connects the back and grasps the data of memory by microprocessor or data processor, and has been transmitted by a holding wire DO with a specific data format and to comprise data and unlike signals such as clock pulse and demonstration simultaneously.
In the embodiment shown in Figure 15 A and Figure 15 B, the utility model data transmission dual mode of giving an example, the first adds the method for clock pulse with voltage level, shown in Figure 16 A.Before power supply changeover device 20 began to transmit data, holding wire DO was the free of data state, represents with the voltage level of 1/2VDD.When power supply changeover device 20 begins to transmit data, the data of the performed instruction of each RGB LED light lamp 10 are represented in " 1 " of data signal or " 0 ", and carrying out which kind of action then can predefined.
Transmit in the process of data, every " 1 " or " 0 " necessarily is returned to the 1/2VDD voltage level and then transmits next position when finishing, therefore can comprise data and clock pulse simultaneously.After then the control circuit 14 in each RGB LED light lamp 10 waits to receive these data,, and pass to next stage LED light lamp 10 again after being handled and encode the data to identical signal format through inner decipher identification.And each lamp string of synchronous light-emitting diode has promptly defined the sum of LED light lamp 10 at the beginning of planning, when so microprocessor or data processor need change brightness at every turn, promptly transmit the hyte that is equal to LED light lamp group sum, then data are by the one-in-and-one-out of each RGB LED, and each hyte is with suitable being delivered in each LED light lamp 10.
After the data transmission finishes then, the pin DO of holding wire DO and LED light lamp 10 will stay in the accurate position of 1/2VDD, and the utility model embodiment can define above certain hour when 1/2VDD appears in each DO, then with data interlock and show.Thus, as long as change different memory contents, then the utility model embodiment can obtain different flickers or show the lamp string that changes, and the lamp string of this embodiment has preferable Flexible Design.
Another data transmission can be shown in Figure 16 B with the form coding of data.The transmission of data and clock pulse is carried out in numeral " 1 " and " 0 " with preset time interval, same in can defining when general during no any data such as signal stay in VDD or VSS; When surpassing a period of time, then be expressed as and pin instruction and show variation.So also can successful reaching with signals such as a holding wire Data transmission, clock pulse and demonstrations simultaneously.Both difference are that mainly the former belongs to the static mode Identification Data, and the latter then needs each RGB LED light lamp 10 domestic demand to produce clock pulse voluntarily with Identification Data.
The design of lamp string is except the synchronous idea of the utility model, if but whether the lamp string is only made synchronous change in color too dull? so preferably both can accomplish and to change synchronously, again can the asynchronous flicker of intercropping in the time of a certain section, so the design variation of lamp string is just enough abundant.At present traditional lamp string has multiple style, as running lamp, chasing etc.The utility model LED lamp string also can be accomplished these functions, in embodiment of the present utility model, earlier the LED lamp is categorized into several, as No. one, No. two, No. three etc.When entering when running lamp or chasing function, the control circuit of LED lamp is complied with the in addition synchronizing frequency of delayed sync signal of the kind of being classified, and then can reach to run lamp or chase and wait this class function.For example, as be numbered the control circuit of No. one LED lamp, and then synchronizing frequency being postponed fixing a period of time, the LED lamp of numbering No. two then will be with fixing two times of a period of time of rate delay again and again, the rest may be inferred, the phenomenon that then promptly can occur running lamp or chase etc.
In different embodiment of the present utility model, the fixing bright a kind of color of LED lamp, No. two bright another colors of LED lamp by that analogy, every is the conversion different colours through after a while, then also can show the effect that multiple color is chased.According to the LED lamp string that the utility model is implemented, can design more complete, diversified lamp string product.
After describing preferred embodiment of the present utility model in detail, those skilled in the art can clearly understand, can carry out various variations and change not breaking away under claim scope and the spirit, and the utility model also is not subject to the embodiment of illustrated embodiment in the specification.
