2. The Prior Art
The known LED lamp has several features, such as high illuminating efficiency, long service life and low power consumption etc., therefore, LED lamps have already dramatically replaced traditional light bulbs in recent years, and meanwhile it has been widely applied to various decorative light string markets.
Upon the application for light strings, a plurality of known LED lamps 15 are cascaded all together, in which, the input end of sync signal 16 of each LED lamp module 15 is being connected to the control center, so that the control center will be able to control and make each LED lamp module 15 illuminating, flashing or changing colors while transferring sync control signals to input end of sync signal 16 of the said LED lamp module 15. However, the above-mentioned operational mode only can control the light strings consisting of the known LED lamp module 15 to operate synchronously, and it is impossible to addressing control the operation of each individual LED lamp module 15 to execute the special effects, such as marquee or specific arrangement of texts and images for meeting special requirement.
Since the known LED lamp module 15 does not have any dynamically address-generating function, therefore, once an operator is trying to address each LED lamp module 15, the said operator must pre-write each specific address into each corresponding LED lamp module 15 respectively, so that it is able to successfully control each individual LED lamp module 15 with pre-write address. However, there seems to be a lack of flexibility while using pre-write addresses to configure relevant circuit modules and moreover, it is impossible to change the pre-write addresses to meet the future needs. Furthermore, when it is being applied to light strings, the control center will be unable to accurately control each LED lamp module 15 unless it can record the corresponding information related to the location and address allocated for each LED lamp module 15 in advance, and under this circumstance, not only the relevant operations will become more complicated, but also it has to raise a lot of hardware costs in addition to extra memory spaces.***
The disadvantages of the known technique are as follows:
1. The known LED lamp module does not have any dynamically address-generating function;
2. The known LED lamp module seems to be a lack of flexibility while using pre-write addresses to control each individual circuit module; and
3. Whenever the known LED lamp module is being applied to light strings, its control center must record the corresponding information related to the location and address allocated for each LED lamp module, so that it must waste a lot of money on hardware costs due to a complicated allocation operation and extra memory spaces.
Thus, how to improve above-mentioned disadvantages of the known technique to make LED lamp module having a dynamically address-generating function seems to be a major concern for the present invention.
The purpose of the present invention lies in providing a novel and advanced circuit module device with addresses generated by method of divided voltage, in which, a plurality of resistances are being electrically connected all together in series, and also the ADC input ends of a plurality of circuit modules are being electrically connected to the corresponding a plurality resistances so as to make an area between the ADC input ends of two adjacent circuit modules being electrically connected with one resistance, and in this way, it will be able to create different voltage value for each individual ADC input end of each circuit module, and furthermore, having an effect of specific voltage divided by the resistance, it will, therefore, sucessfully allocate varied addresses for a plurality of said circuit modules by using varied voltage values created thereto.
In order to fulfill the above specific purposes, hence, the present invention presents a kind of circuit module device with address generated by method of divided voltage, which comprises:

Wherein, a plurality of said circuit modules comprise at least one primary circuit module, one secondary circuit module and one third circuit module; also a plurality of said resistances comprise at least one primary resistance and one secondary resistance; and thereat, the said primary resistance is connected to the said secondary resistance in series, also the said primary resistance is being electrically connected to a position between the ADC input ends of the said primary circuit module and the said secondary circuit module; and the secondary resistance is being electrically connected to a position between the ADC input ends of the said secondary circuit module and the said third circuit module; and thereby, the said primary circuit module, the said secondary circuit module and the said third circuit module is able to convert, via Analog-to-Digital Converter (ADC), individual voltage value on the ADC input end into digital signal respectively, and in addition, while corresponding to different voltage value of said digital signal, while corresponding to different voltage value of said digital signal, the control unit of the said primary circuit module, the said secondary circuit module and the said third circuit module will generate different addresses and thus it will sucessfully complete the addressing operation for a plurality of said circuit modules accordingly.

A circuit module device with addresses generated by method of divided voltage as defined in the preceding paragraphs, wherein, each LED lamp module of a plurality of said LED lamp modules comprises one red light-emitting diode, one green light-emitting diode and one blue light-emitting diode, and also the said control unit is being electrically connected to the said red light-emitting diode, the said green light-emitting diode and the said blue light-emitting diode respectively, so that it will be able to control either the said red light-emitting diode, the said green light-emitting diode or the said blue light-emitting diode making it illuminating, flashing or changing colors.
The present invention will be apparent to those skilled in the art by reading the following detailed description of a preferred embodiment thereof, with reference to the attached drawings, in which:
When there is one voltage being output from one end of the control center 24 connected with the resistances 25, the said output voltage will create a voltage drop at the resistance 25 and 26 and hence contributing varied voltage value to Point A, B or C. Consequently, when circuit module 23, 22, 21 is trying to detect the voltage value on the input end through ADC 232, 222, 212, it will easily obtain varied voltage value from Point A, B or C respectively, and in addition, while converting the analog voltage values detected by the said ADC 232, 222, 212 into digital signals, the control unit will correspond to the varied voltage values contained in the said digital signals and generate different addresses for relevant circuit module accordingly. For example: when resistance 25 and 26 has a same resistance value, supposed the voltage value output from the control center 24 is 2V, then relative voltage value applied on Point A, B or C will be 2V, 1V or 0V respectively. Therefore, ADC 232, 222, 212 will convert the analog voltage value of 2V, 1V and 0V into corresponding digital signal so as to make each individual control unit of the circuit module 23, 22, 21 creating different address 2, 1 and 0 respectively. Thus, after the completion of addressing operation, the said control center 24 will be able to further control the illuminating effects of specific circuit module just by simply adding the address information into each control signal.
Certainly, it is allowable to make the control center 24 outputting varied voltage values, also to adopt different resistance values for the resistance 25 and 26 resistivity, and instead, at one end of resistance 26 that is being connected to one end of ADC 212 originally. Besides, it is allowable to increase more units of circuit modules as well as the corresponding resistances.
On the other hand, the control center 24 is able to send out the specific addressing command from one end connected with the signal input end 211, 221, 231 in order to drive the circuit module 21, 22 and 23 to execute the addressing operation synchronously.
When it is being applied to light strings, it is allowable to directly give one addressing command to signal input end 36 of LED lamp module 35 to drive all LED lamp modules generating specific addresses automatically. Since the addresses generated by the said LED lamp module 35 has a direct relationship with the resistances of the said LED lamp module 35, so that the control center will be able to accurately control each individual LED lamp module without particularly recording the corresponding information related to the location and address allocated for each LED lamp module 35 in advance.
The advantages of the present invention are as follows:
1. The circuit module device with addresses generated by method of divided voltage provided in accordance with the present invention can dynamically generate specific addresses by way of detecting the voltage value on relevant nodes;
2. The circuit module device with addresses generated by method of divided voltage provided in accordance with the present invention need not to pre-write any address at all, it can be executed in a very flexible way, that is, the corresponding addresses can be generated only after the completion of the configuration operation for relevant circuit modules; and
3. Upon the application of the light strings, there is no need at all for the control center of the circuit module device with addresses generated by method of divided voltage provided in accordance with the present invention to record the allocated address along with corresponding information of its allocated address for each LED lamp module, and in this way, not only its installation operation will become much more easier, but also it can save a lot of hardware costs without extra memory spaces.
