Description
BACKGROUND OF THE INVENTION

1. Field of the Invention


The present invention relates generally to a kind of LED lamp module with address generation functions, and more specifically it relates to a LED lamp module with address generation functions that is able to convert an analog voltage at one node into a digital voltage value by means of an Analog-to-Digital Converter (ADC), and then it will determine a specific address for the said module pursuant to the said digital voltage value thereof.


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. FIG. 1 is a schematic view showing a known LED lamp module, wherein, it comprises red light-emitting diode 11, green light-emitting diode 12, blue light-emitting diode 13, control unit 14, LED lamp module 15 and input end of sync signal 16 etc. The known LED lamp module 15 consists of red light-emitting diode 11, green light-emitting diode 12, blue light-emitting diode 13 and control unit 14. Whereby, control unit 14 is being electrically connected with red light-emitting diode 11, green light-emitting diode 12 and blue light-emitting diode 13 respectively, which can independently control and make each light-emitting diode illuminating, flashing, selecting color combinations and/or changing colors respectively. Additionally, the control unit 14 is being further electrically connected to the input end of sync signal 16 in order to control the operation of light-emitting diode 11, 12, or 13 while responding to the sync signals received by the signal input of sync signal 16.


Upon the application for the 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 the light strings illuminating, flashing and/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 for the light strings, such as marquee or specific arrangement of texts and images in order to meet special requirements.


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 at all;


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 the 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIG. 2, it is a schematic view showing a preferred embodiment of LED lamp module with address generation functions in accordance with the present invention, in which, it comprises the red light-emitting diode 21, green light-emitting diode 22, blue light-emitting diode 23, control unit 24, Analog-to-Digital Converter (ADC) 25, memory unit 26, LED lamp module 27, power pin 28, signal input pin 29, ADC input pin 210 and grounding pin 211 etc. The LED lamp module 27 consists of red light-emitting diode 21, green light-emitting diode 22, blue light-emitting diode 23, control unit 24, Analog-to-Digital Converter (ADC) 25 and memory unit 26, and it further comprises the power pin 28, signal input pin 29, ADC input pin 210 and grounding pin 211. Moreover, the LED lamp module 27 is being electrically connected with one power supply via the said power pin 28 and the grounding pin 211 is being electricity connected to the ground.


The control unit 24 is being electrically connected to the red light-emitting diode 21, green light-emitting diode 22, blue light-emitting diode 23, Analog-to-Digital Converter (ADC) 25 and memory unit 26 respectively, and thereby, it is able to individually control each LED to make it illuminating, flashing, mixing colors and/or changing colors. The Analog-to-Digital Converter (ADC) 25 can convert one analog voltage value on the ADC input pin 210 into one digit voltage value, and then delivering it to the said control unit 24, and moreover, while responding to the said digital voltage value, the said control unit 24 will generate one corresponding address and also to store the said address in the said memory unit 26. Therefore, while LED lamp module 27 is receiving one addressing command through the signal input pin 29, it will follow the above-mentioned method to generate one corresponding address pursuant to the voltage value on the ADC input pin 210, and in this way, it will make the said control unit 24 be able to control the illumination of the red light-emitting diode 21, green light-emitting diode 22, or blue light-emitting diode 23.



FIG. 3 is a schematic view showing a preferred embodiment of LED lamp module with address generation functions, which is being applied to light strings, in accordance with the present invention, in which, it comprises the LED lamp module 31, 32, 33, the signal input pin 311, 321, 331, Analog-to-Digital Converter (ADC) 312, 322, 332, control center 34, resistance 35, 36 as well as the grounding 37. Whereby, after the signal input pin 311, 321, 331 of LED lamp module 31, 32, 33 has received relevant addressing commands from the control center 34, the LED lamp module 31, 32, 33 will convert, through Analog-to-Digital Converter (ADC) 312, 322, 332, the analog voltage value at Point A, B, C, into digital voltage value respectively, and hence generating corresponding addresses accordingly. Due to the voltage on Point A output by the said control center 34 will create a voltage drop at the resistance 35 and 36, therefore, the voltage value created on Point A, B or C is varied, and under this circumstance, it will hence generate different address for the LED lamp module 31, 32, 33. For example: when resistance 35 and 36 has a same resistance value, supposed the control center 34 outputs 2V voltage to Point A, then the relative voltage value created at Point A, B or C will be 2V, 1V or 0V respectively. Therefore, Analog-to-Digital Converter (ADC) 332, 322, 312 will convert the analog voltage value of 2V, 1V and 0V into corresponding digital voltage value and then delivering it to each individual control unit respectively, so as to accomplish the addressing operation by making the control unit on LED lamp module 33, 32, 31 to generate different address 2, 1 and 0 respectively. Thus, after the completion of addressing operation, the said control center 34 will be able to further control the illuminating effects of specific LED lamp module just by simply adding address information into each control signal.


Certainly, it is allowable to make the control center 34 outputting varied voltage values, also to adopt different resistance values for the resistance 35 and 36 resistivity, and instead, at one end of resistance 36 that is being connected to one end of ADC 312 originally. Besides, it is allowable to increase more units of LED lamp modules as well as the corresponding resistances.
