Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 to 3 of the drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
In the description of the present invention, it should be noted that, if the terms "upper", "lower", "inner", "outer", and the like indicate an azimuth or a positional relationship based on the azimuth or the positional relationship shown in the drawings, or the azimuth or the positional relationship in which the inventive product is conventionally put in use, it is merely for convenience of describing the present invention and simplifying the description, and it is not indicated or implied that the apparatus or element referred to must have a specific azimuth, be configured and operated in a specific azimuth, and thus it should not be construed as limiting the present invention.
Furthermore, the terms "first," "second," and the like, if any, are used merely for distinguishing between descriptions and not for indicating or implying a relative importance.
It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.
In one embodiment, the present invention provides an address signal processing apparatus for an LED lamp, characterized in that:
the address signal processing device comprises a processing unit and three ends, wherein the processing unit is connected with a first end, a second end and a third end of the three ends,
the first end, the second end and the third end respectively comprise 1 signal end, the signal ends are respectively a first signal end, a second signal end and a third signal end, wherein,
the first signal end is used for connecting a signal input DIN of a front stage of the address signal processing device;
the second signal end is used for connecting with the signal input end of the current LED lamp string at the second end;
and the third signal end is used for being connected with the first signal end of the same address signal processing device at the later stage of the address signal processing device.
Therefore, the processing unit recodes the address codes of the LED light emitters in the current LED light string through the second signal end according to the signals obtained by the first signal end, so that each LED light emitter in the LED light string can normally work under the action of the signal input DIN of the front stage. It can be appreciated that, instead of recoding the address code of the LED luminary, the processing unit can recode the signal on the signal line so that it can correctly correspond to the corresponding LED luminary, as can be appreciated from the correspondence between the signal transmitted on the signal line and the address of the LED luminary. It will be appreciated that these are two coding schemes that can be flexibly selected based on their correspondence, and that whichever scheme is used, the address related signal is recoded without regard to the other data signal in the narrow sense of how the LED luminary emits light, since whatever is done to properly drive the LED luminary to function properly, and of course without regard to modification of the data signal in its narrow sense.
Taking address recoding as an example, for the above embodiment, when the device is used for a curtain lamp, the device only needs to be arranged on a curtain lamp bracket body, so that a signal loop can be canceled, but the addresses of all LED luminous bodies in the LED lamp string can continue according to the same rule on the basis of a front-stage LED lamp string. Therefore, all address codes can be uniformly and once coded for all LED lamp strings without leaving the factory according to a certain rule. Furthermore, it should be noted that, due to such recoding, the present invention facilitates recoding in case of a failure of a certain LED, for example, only the failed LED in the previous LED string needs to be removed, and then the address codes of the plurality of LED luminaries in the current LED string are recoded by the processing unit.
Further, in one embodiment, the first and second processing elements,
the first-stage LED lamp string and the second-stage LED lamp string are identical in initial address coding.
The most important positive effects are due to the presence of the address signal processing means: each LED string address may be made identical. Only need during the use, by connecting the corresponding address signal processing device of this level LED lamp cluster to recode it.
In one embodiment of the present invention, in one embodiment,
the address signal processing device further includes a memory in which an address of the address signal processing device is stored.
For example, when the first-stage LED string and the second-stage LED string are independently produced, the addresses of the 20 LED light emitters are 1-20, and when the two-stage LED string and the address signal processing device form an LED lamp, such as a curtain lamp, the address signal processing device connected with the second-stage LED string stores the own address of 20, the address of the second-stage LED string continues to be recoded downwards to be 21-40 after the address of the last 1 LED light emitter of the first-stage LED string, and the like.
In one embodiment of the present invention, in one embodiment,
the address of the address signal processing device is preset.
Still further, in one embodiment,
the processing unit of the address signal processing device resets the address of the address signal processing device by acquiring a signal input of a preceding stage.
Typically, when the first stage LED string is in a serial relationship with the second stage LED string, then, assuming that the current address signal processing device is connected to the second stage LED string, then, the signal input of the previous stage may be from the last 1 LED emitters of the first stage LED string, and as described above, the address of the last 1 LED emitters of the previous stage is 20, so, after obtaining this address, the current address signal processing device may reset the address of the address signal processing device, and recode the address of the 1 st LED emitter of the second stage LED string according to the address of the address signal processing device after resetting, thereby further implementing recoding the address of all LED emitters of the second stage LED string. In fact, for a plurality of LED lights in the same LED string, each LED light may include an LED light bead and an IC, and after each LED light processes its own light emission according to the signal input, a new signal output may be provided to the remaining LED lights, where the signal output may enable the IC of the remaining subsequent LED lights to accurately identify the incoming signal and enable the remaining subsequent LED lights to operate normally. Of course, the present invention does not exclude the processing unit from recoding the address of each LED luminary in the LED string to which it is connected.
In one embodiment of the present invention, in one embodiment,
the three ends of the address signal processing device are all plug-in terminals, so that the address signal processing device is conveniently connected with the front stage, the rear stage and the current LED lamp string.
It can be understood that the pluggable design is for facilitating subsequent maintenance and production.
In one embodiment of the present invention, in one embodiment,
the LED lamp at least comprises a first-stage LED lamp string and a second-stage LED lamp string, each LED lamp string comprises a plurality of LED luminous bodies, and the plurality of LED luminous bodies are sequentially provided with corresponding address codes.
It should be noted that the number of the substrates,
in one embodiment of the present invention, in one embodiment,
the first end, the second end and the third end respectively comprise 2 power supply ends;
the first end includes: a first positive terminal, a first negative terminal;
the second end includes: a second positive terminal, a second negative terminal;
the third terminal includes: and a third positive terminal and a third negative terminal.
In one embodiment of the present invention, in one embodiment,
the first-stage LED lamp string and the second-stage LED lamp string are serial lamp strings.
In one embodiment of the present invention, in one embodiment,
the first-stage LED lamp string and the second-stage LED lamp string are parallel lamp strings.
In one embodiment of the present invention, in one embodiment,
the address signal processing device is used for the LED lamp string with the voltage of 5V or 12V.
In one embodiment of the present invention, in one embodiment,
when the device is used for a 12V LED lamp string, the address signal processing device comprises a resistor connected with the processing unit.
In addition, the invention also discloses an LED lamp which adopts the address signal processing device.
In one embodiment of the present invention, in one embodiment,
the LED lamp can work at 110V-230V and only needs to be provided with a corresponding AC/DC module.
It will be appreciated that the invention is not limited to voltages of 110V, 230V, etc., and may be other power supply voltage standards, or may be a wider voltage range.
Fig. 1 to 3 illustrate the situation when the address signal processing apparatus of the present invention is implemented as a shifter, and it can be understood that the shifting processing manner is a convenient manner for the processing unit, especially for consecutively numbered addresses.
Taking fig. 1 as an example, the shifter, the surrounding circuit and the LED string are configured into a T-shaped structure when in use, wherein the upper part of the T-shape is a horizontal representation of the surrounding circuit, in particular a bus, and the bus comprises a signal input line from top to bottom, a negative electrode line and a positive electrode line for direct current power supply; on the side of the processing unit facing the user, the displacement lamp beads are presented in front of the user, and the working condition of the address signal processing device, namely the displacer at the position, is displayed through the lamp bead change; the signal output end of the shifter is used for outputting to a light string, the signal output end is connected with the light string signal end of the LED light string longitudinally indicated below the T shape, and the corresponding connection of the two signal ends is used for realizing the function of the shifter as an address signal processing device; as for the connection of the positive electrode, the negative electrode, etc., one-to-one correspondence, it is understood that this is not critical to the present invention, but is only necessary for power supply. It is apparent that the key of the present invention is the terminals and processing units associated with the signals. Displacing the light beads is just one means of enhancing the user experience of such embodiments of the displacer.
For example, the address of the shifter is 20 as described above, and the front-stage light string comprises 20 LED light emitters from 1 to 20, the processing unit of the current shifter can directly encode the address code of the LED light string longitudinally indicated below the T-shape in fig. 1 from 1 to 20 to 21 to 40. Of course, as mentioned above, from the opposite angle, the signal transmitted on the signal line may be encoded into the signal corresponding to 1 to 20, so that the address of the LED luminary is not changed, and the signal can still be matched with the corresponding LED luminary to work normally.
It should be emphasized that in a preferred embodiment, in the T-shaped structure, the three ends of the displacer are all plug-in terminals, so that the displacer can be conveniently connected with the front-stage and rear-stage circuits in the transverse direction and the current LED light string in the longitudinal direction.
Fig. 2 illustrates a parallel connection type curtain lamp, in which, taking the back of the curtain lamp holder as an example, each shifter is in a completely connected and parallel connection relationship with a transverse bus illustrated by a T-shape, and a signal main line is also in a connected and parallel connection relationship, even if a front-stage LED lamp string is broken, a rear-stage LED lamp string can still receive signals and positive and negative electrodes are used for supplying power; wherein, for a 12V displacer, the displacer further includes a resistance of 2.4k to 3k ohms to improve withstand voltage;
in contrast to fig. 2, fig. 3 illustrates that when the device is used in a serial curtain lamp, the signal main line is not connected in the front-back stage, but further transmits signals to the back stage through the front stage, and if the displacement lamp beads in the displacement device are regarded as the processing units, the device is as follows: the output signal of the displacement lamp bead is directly transmitted to the input end of the next displacement lamp bead. It can be understood that the positive and negative electrodes can still be communicated, so that the LED lamp strings at all levels can be ensured to be relatively independent in power supply. However, for a series type curtain lamp, the advantages of the invention can be further represented in extreme cases: if a certain LED light emitting body in the front-stage LED light string fails, and the LED light emitting body is removed by operation staff, if the LED light emitting body is recoded by the lower-stage shifter, the rest normal LED light emitting bodies in the front-stage LED light string can normally work after operation and maintenance, and all normal light emitting bodies in the rear-stage LED light string can normally work. In contrast, without the shifter or the address signal processing device of the present invention, since address information is fixedly written in the past, in the prior art, the post-stage LED light string cannot work normally in the face of the situation. This apparent effect is also similar for the parallel type window covering lamp shown in fig. 2.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present invention should be included in the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
