Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. The components of 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 present invention, 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 derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," and the like are used merely to distinguish one description from another, and are not to be construed as indicating or implying relative importance.

In the prior art, multi-color lamps are usually used as indicator lamps, and the operating state of the device or module is indicated by the corresponding color of the lamp light. Some devices need to be provided with a plurality of multi-color lamps to serve as corresponding indicator lamps, and the plurality of multi-color lamps are usually arranged in a centralized manner in order to save space. When the multicolor lamps are arranged in a centralized way, the multicolor lamps are easy to form the problem of light channeling due to the quality problem. For example, a red light and a green light may form a yellow light after being mixed, and thus, a manager may easily determine the operation state of the device or the module by mistake due to the color of the mixed light. In the prior art, whether each lamp bead in the multicolor lamp can emit light or not can be generally judged singly, and the problem of light fleeing of the multicolor lamp is difficult to find when the multicolor lamp is detected.

The present inventors have found the above problems through long-term research and research, and proposed the following examples to solve the above problems. The following describes embodiments of the present invention in detail with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1, a schematic structural diagram of a testing apparatus 10 according to an embodiment of the present invention is shown, in which the testing apparatus is matched with a multi-color lamp 20 during testing. The test equipment 10 provided by the embodiment of the invention can detect the light channeling problem of the multicolor lamps 20, and is convenient for operators to find the light channeling problem of the multicolor lamps 20 in time. The test apparatus 10 may include a controller 11, among other things. The multi-colored lamp 20 may include a plurality of beads 23 each for emitting a single color. During testing, the plurality of multicolor lamps 20 are linearly arranged or arrayed, the testing device 10 can test the multicolor lamps 20 which are linearly arranged or arrayed, and can determine whether the multicolor lamps 20 have a light channeling problem according to the light emitting colors of the multicolor lamps 20. For example, the controller 11 may control a plurality of multi-colored lamps 20 to emit light. Specifically, for example, a part of the multi-color lamps 20 is controlled to emit light of a first color, and another part of the multi-color lamps 20 is controlled to emit light of a second color. If the light channeling problem occurs, light of another color (different from the first color and the second color) is formed between adjacent lamps, so that the light channeling problem (or light channeling fault) is exposed, and an operator can find out the fault lamp conveniently.

Specifically, for example, among the plurality of multicolor lamps 20 shown in fig. 1, the multicolor lamp 20 of serial No. 4 is the multicolor lamp 20 in which the problem of crosstalk occurs. If the multicolor lamp 20 only lights red light, and the other multicolor lamps 20 light green light, then the light path intersection at a short distance between the multicolor lamp 20 of serial number 4 and the multicolor lamp 20 of serial number 3 will appear yellow light, and the light path intersection at a short distance between the multicolor lamps 20 of

serial numbers

4 and 5 will also appear yellow light, and the operator can determine the position of the multicolor lamp 20 with the light fleeing problem according to the yellow light position.

Understandably, if the distance of intersection of two adjacent multicolor light paths is far, even if the light of two different colors is mixed at a far distance, the influence of light channeling is not great, if the light channeling area is far away from the multicolor lamp 20, the light color of the multicolor lamp 20 at a near place can not be observed by an operator, because the light color at the near place is the light color actually emitted, the light color after light channeling at the far intersection is the light color, that is, under the condition, the operator can directly determine the actual light color emitted by the multicolor lamp 20 (the distance of intersection of the light paths is far).

In the indicator light industry, an operator cannot judge the light color wrongly due to the light fleeing formed in the area far away from the multicolor light 20, and can judge the light color wrongly due to the light fleeing formed in the area near the multicolor light 20, so that the error judgment of the equipment state is further caused. The light fleeing problem of the multicolor lamp 20 is detected by the scheme, so that the light fleeing problem formed by the multicolor lamp 20 in a near area can be detected and avoided, and the corresponding state of the equipment can be determined by an operator according to the normal color of the indicator lamp, and the state of the judged equipment can not be wrong due to the indication of wrong color.

It should be noted that the multi-color lamp 20 may be a multi-color LED lamp capable of emitting a plurality of lighting colors. The number of simultaneous tests of the multi-color lamps 20 by the test apparatus 10 may be set according to practical circumstances and is not particularly limited herein.

Referring to fig. 2, a schematic diagram of a testing circuit for connecting the testing device 10 and the multi-color lamp 20 according to an embodiment of the present invention is shown. The test circuit schematic diagram shown in fig. 2 is a schematic circuit diagram when the controller 11 is connected to one multi-color lamp 20, and in this embodiment, the controller 11 may be connected to a plurality of multi-color lamps 20 at the same time.

The controller 11 in the test device 10 may be replaced by another device to achieve the same or similar functional effects as the test device 10. Other devices include, but are not limited to, Personal Computers (PCs), tablet computers, Personal Digital Assistants (PDAs), Mobile Internet Devices (MIDs), and the like.

In this embodiment, the testing device 10 may include a controller 11 and a storage module 12, and the respective elements of the controller 11 and the storage module 12 are directly or indirectly electrically connected to realize data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines.

The controller 11 may be an integrated circuit chip having signal processing capabilities. The controller 11 may be a general-purpose processor. For example, the processor may be a Central Processing Unit (CPU), a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components. The various methods, steps and logic blocks disclosed in the embodiments of the present invention may be implemented or performed.

The memory module 12 may be, but is not limited to, a random access memory, a read only memory, a programmable read only memory, an erasable programmable read only memory, an electrically erasable programmable read only memory, and the like. In this embodiment, the storage module 12 may be configured to store a preset test rule. Of course, the storage module 12 may also be used to store a program, which the controller 11 executes after receiving the execution instruction.

It will be understood that the structure of the test device 10 shown in fig. 2 is only a schematic diagram of the structure of the test device 10, and the test device 10 may further include more or less components than those shown in fig. 2, for example, the test device 10 may further include a power supply module, or the memory module 12 is integrated in the controller 11, so that the controller 11 also has the corresponding functions of the memory module 12. The components shown in fig. 2 may be implemented in hardware, software, or a combination thereof.

In this embodiment, the controller 11 is configured to control, according to a preset test rule, the corresponding lamp beads 23 in the multiple multicolor lamps 20 to be electrically connected, so that a part of the multiple multicolor lamps 20 emit first-color light, and another part of the multiple multicolor lamps 20 emit second-color light. The multicolor lamp 20 may be a two-color lamp, a three-color lamp, a four-color lamp, or the like, which can emit light of various colors. For example, the three-color lamp can be a lamp formed by two lamp beads 23, the two lamp beads 23 can respectively emit light with two different colors, and when the two lamp beads 23 emit light simultaneously, the light with two different colors is mixed and changed to form light with a third color, so that the three-color lamp is formed. Or the three-color lamp is a lamp formed by three lamp beads 23, each lamp bead 23 is used for emitting a single-color light, and the type of the lamp beads 23 in the multi-color lamp 20 and the implementation process of multi-color light emission are not particularly limited.

For example, the multi-color lamp 20 shown in fig. 2 may be implemented as a three-color lamp, which may operate as follows:

the controller 11 only controls the first switch to be at a high level, and the first electric control switch 21 is turned on, so that the first lamp bead 23 emits the first color light. The controller 11 only controls the second switch to be at a high level, and the second electric control switch 22 is turned on, so that the second lamp bead 23 emits light of the second color. If make two switches at the high level simultaneously, two lamp pearls 23 all give out light and mix and form third colour light.

The controller 11 is also configured to determine an abnormal condition of the multi-color lamps 20 based on the light colors emitted from the respective multi-color lamps 20. For example, the controller 11 may cooperate with a color sensor to determine an abnormal condition of the multi-colored lamp 20. When there is a lighting color different from the first color and the second color in the lighting color emitted from each of the multicolor lamps 20, it is determined that the abnormal condition existing in the plurality of multicolor lamps 20 is a light leakage failure.

Optionally, the testing device 10 may further include a plurality of sets of socket switches, each set of socket switches including a first electrically controlled switch 21 and a second electrically controlled switch 22; the first electric control switch 21 is connected with a first lamp bead 23 in the multicolor lamp 20 and is used for controlling the first lamp bead 23 to emit first color light; the second electric control switch 22 is connected with a second lamp bead 23 in the multicolor lamp 20 and is used for controlling the second lamp bead 23 to emit light with a second color.

Optionally, the test device 10 may also comprise a plurality of lamp sockets, each for electrically connecting with one multi-coloured lamp 20. Each multi-color lamp 20 may include a first lamp bead 23, a second lamp bead 23, a first electrical control switch 21, and a second electrical control switch 22.

Understandably, the electrically controlled switch may be included as part of the test apparatus 10, or the electrically controlled switch may be included as part of the multi-colored lights 20. Wherein, first automatically controlled switch 21 all is connected with controller 11 with second automatically controlled switch 22, and first automatically controlled switch 21 sets up on the circular telegram circuit of first lamp pearl 23, can make first lamp pearl 23 send first colour light when first automatically controlled switch 21 switches on. Second electrical switch 22 sets up on the circular telegram circuit of second lamp pearl 23, and second electrical switch 22 can make second lamp pearl 23 send second colour light when switching on. That is, the first electronically controlled switch 21 and the second electronically controlled switch 22 are both turned on or off under the control of the controller 11.

Optionally, the testing device 10 may further include a power module connected to the controller 11, and the power module may provide power to the controller 11. Alternatively, the power module may also provide power to a plurality of multi-colored lamps 20. For example, the power supply module may be connected to a power conversion chip to output current to the plurality of multi-colored lamps 20. That is, the power supply module may supply power to the controller 11, or may supply power to the plurality of multi-colored lamps 20.

Fig. 3 is a schematic flow chart of a testing method for a multi-color lamp 20 according to an embodiment of the present invention. The method for testing the multicolor lamp 20 provided by the invention can be applied to the test equipment 10, and the test equipment 10 realizes the steps of the method for testing the multicolor lamp 20, so that an operator can quickly position the multicolor lamp 20 with the problem of light channeling based on the method.

As will be explained in detail below with respect to the steps of the method shown in fig. 3, in the present embodiment, the multi-color lamp 20 testing method may include the steps of:

step S210, controlling the electrical conduction of the corresponding lamp beads 23 in the multiple multi-color lamps 20 according to a preset test rule, so that a part of the multi-color lamps 20 emit light of a first color, and another part of the multi-color lamps 20 emit light of a second color.

Understandably, at the beginning of the test, a plurality of multicolor lamps 20 are arranged in a linear form or in an array form and are installed on the test equipment 10, so that the multicolor lamps 20 with the light channeling problem can be intersected on the light paths of other multicolor lamps 20 which are close to the multicolor lamps 20, and the light channeling problem is exposed, so that an operator can quickly locate the fault lamp. The specific light color and color type that the multicolor lamp 20 can emit can be set according to actual conditions, and the light color and color type that the multicolor lamp 20 can emit are not specifically limited here.

In this embodiment, the multi-color lamp 20 may include a first lamp bead 23 and a second lamp bead 23, the testing device 10 includes a plurality of sets of lamp socket switches, each set of lamp socket switches includes a first electric control switch 21 and a second electric control switch 22; the first electric control switch 21 is connected with the first lamp bead 23 and is used for controlling the first lamp bead 23 to emit first color light; and the second electric control switch 22 is connected with the second lamp beads 23 and is used for controlling the second lamp beads 23 to emit light with a second color.

Alternatively, the multi-color lamp 20 may be a three-color lamp for emitting light of a first color, light of a second color, and light of a third color. And the third color light is formed by mixing the first color light and the second color light.

Specifically, reference may be made to fig. 4, which is a state table diagram of light emission control with the multi-color lamp 20 shown in fig. 1. For example, the testing device 10 may simultaneously test 8 multi-colored lights 20, wherein the multi-colored lights 20 may be three-colored lights, such as three-colored LED lights. The preset test rule may be: firstly, the 8 multicolor lamps 20 are controlled to be uniformly bright red, all the multicolor lamps 20 are controlled to be uniformly bright green after 0.5 second, all the multicolor lamps 20 are controlled to be bright yellow after 1 second (if unlighted multicolor lamps 20 exist or multicolor lamps 20 of other colors are lighted, the fault of poor contact of the multicolor lamps 20 can be determined), the multicolor lamp 20 of the serial number 1 is controlled to be bright green after 1.5 seconds, the rest multicolor lamps 20 are bright red, the next serial number multicolor lamp 20 is switched to be bright green every 0.5 second, the rest multicolor lamps 20 are bright red until the multicolor lamp 20 of the serial number 8 is bright green, the rest multicolor lamps 20 are bright red (if fleeing light occurs, yellow light can be formed between the adjacent multicolor lamps 20), and then all the multicolor lamps 20 are controlled to be extinguished (if the multicolor lamps 20 which cannot be extinguished exist, the fault of contact of the multicolor lamps 20 can be determined).

Understandably, in the testing method for the multicolor lamp 20, in addition to detecting the light channeling failure of the multicolor lamp 20, it may also detect whether each lamp bead 23 emits light normally, for example, control the corresponding lamp bead 23 in all the multicolor lamps 20 to emit light red, and if there is no light emission of the multicolor lamp 20, that means that the lamp bead 23 emitting light red in the multicolor lamp 20 has a failure, the failure includes, but is not limited to, a poor contact of the lamp bead 23, a damaged lamp bead, and the like.

In addition, the test device 10 and the plurality of multi-colored lamps 20 may be integrated in one system. The test method can be used for detecting a plurality of multi-color lamps 20 before the system runs, and is helpful for eliminating the faults of the multi-color lamps 20. For example, in an electromechanical system, it is usually necessary to determine the operating state of the corresponding functional module by using the plurality of multicolor lamps 20, the above-mentioned testing method may be used as an initialization process of the electromechanical system to detect an abnormal state of the multicolor lamps 20, if it is detected that the multicolor lamps 20 are not in failure, the electromechanical system starts to operate, and the indication of various states of the electromechanical system is realized by using the on-off states and the lighting colors of the plurality of multicolor lamps 20, so that an operator can intuitively determine various operating conditions of the electromechanical system according to the on-off states and the lighting colors of the multicolor lamps 20.

In the above-described table diagram, the

numbers

1, 2, and 3 of the contents in the table diagram may respectively represent three different colors of the

multicolor lamp

20, and 0 may indicate that the multicolor lamp 20 is turned off, excluding the horizontal column corresponding to the number of the multicolor lamp 20 and the vertical column corresponding to the time. For example, numeral 3 indicates that the multi-color lamp 20 emits yellow light, numeral 2 indicates that the multi-color lamp 20 emits red light, and numeral 1 indicates that the multi-color lamp 20 emits green light. Of course, the color of the light indicated by the number may be a color different from the above, and the corresponding color may be set according to the actual situation, which is not limited herein. The time interval between two adjacent control rounds can also be set according to the actual situation, and is not limited specifically here.

In step S220, an abnormal condition of the multi-color lamps 20 is determined based on the light colors emitted by the multi-color lamps 20, wherein when there is a light color different from the first color and the second color in the light colors emitted by the multi-color lamps 20, it is determined that the abnormal condition existing in the plurality of multi-color lamps 20 is a cross light failure.

Optionally, step S210 may include: the first electronically controlled switch 21 of one multi-color lamp 20 of the plurality of multi-color lamps 20 is controlled to be turned on in turn, and the second electronically controlled switches 22 of the remaining multi-color lamps 20 are controlled to be turned on in each turn.

Understandably, in each round of control, one of the multi-colored lamps 20 is controlled to emit light of a first color, and the remaining multi-colored lamps 20 are controlled to emit light of a second color. In the lower-wheel control, the other multicolor lamps 20 which do not emit the first color light, and the other multicolor lamps 20 emit the second color light. Finally, each multi-color lamp 20 emits at least two different colors of light in sequence during the whole test process.

When the light color emitted by each lamp bead 23 has the light different from the first color and the second color, it is determined that the light fleeing fault exists between the lamp bead 23 emitting the first color light and the lamp bead 23 adjacent to the lamp bead 23 emitting the first color light, or it is determined that the light fleeing fault exists between the lamp bead 23 emitting the first color light or the lamp bead 23 adjacent to the lamp bead 23 emitting the first color light.

Based on this, the operator can conveniently determine the position of the multicolor lamp 20 with the light fleeing fault according to the abnormal light color (different from the light colors of the first color and the second color) so as to complete the troubleshooting of the fault lamp.

The determination of the light channeling fault can be determined by visual observation or by using a color sensor sensitive to the color of each light. The method can expose the light channeling fault so that a sensor or an operator can determine the position of the fault lamp directly through naked eyes.

In addition, the inventor of the present application has found that another reason for the light channeling of the multi-color lamp 20 is that the light intensity of the lamp bead 23 is too high. Because luminous intensity is too big just can make the easy scattering of light that lamp pearl 23 sent, and the light that the light of scattering and other lamp pearls 23 sent mixes just to cause and scurries the light problem.

After the channeling problem is found by the method or the testing device 10, an operator can deal with the channeling problem according to the reason causing the channeling problem.

For example, because of scurrying light that lamp pearl 23 luminous intensity was too big to cause, operating personnel can set up divider resistance in series on lamp pearl 23's the power supply line, and its divider resistance's resistance can set up according to actual conditions to reduce lamp pearl 23's luminous intensity. Understandably, the larger the resistance value of the divider resistor is, the smaller the voltage at the two ends of the lamp bead 23 is, the weaker the light intensity is, the weak light is not easy to scatter, or the light scattering capability is reduced, so that the light is not easy to flee. By adopting the method, the problem of light channeling can be detected, and an operator can be assisted to find the divider resistor with a proper resistance value, so that the lamp bead 23 can emit light normally and cannot channel light.

In addition, if the light flees due to the excessive light intensity of the lamp beads 23, the operator can also set a lamp post on the multicolor lamp 20, and the light is irradiated on the lamp post to reflect the color of the light emitted by the lamp beads 23. Isolation colloid can be arranged between the lamp posts and used for isolating the scattered light emitted by the adjacent multicolor lamps 20, so that the scattered light is prevented from fleeing. The lamp post is a cylinder made of transparent material (such as glass, plastic, etc.), and can be directly disposed on or covered on the multicolor lamp 20.

From the above description of the embodiments, it is clear to those skilled in the art that the present invention can be implemented by hardware, or by software plus a necessary general hardware platform, and based on such understanding, the technical solution of the present invention can be embodied in the form of a software product, which can be stored in a non-volatile storage medium (which can be a CD-ROM, a usb disk, a removable hard disk, etc.), and includes several instructions to make a computer device (which can be a personal computer, a server, or a network device, etc.) execute the method described in the embodiments of the present invention.

In summary, the present invention provides a multi-color lamp testing method and testing apparatus.
