Description

LED lighting fixtures and devices for diagnosing failures in LED lighting fixtures {LED LIGHTING APPARATUS AND FAULT DIAGNOSIS APPARATUS FOR LED LIGHTING APPARATUS}

The present invention relates to a device for diagnosing a malfunction of an LED lighting fixture and an invention related to an LED lighting fixture capable of diagnosing a malfunction.

Conventionally, the light sources of lighting widely used in general homes and offices include incandescent bulbs or fluorescent lamps. These incandescent bulbs or fluorescent lamps not only waste resources due to their high power consumption and have a negative impact on environmental protection, but also have a negative impact on environmental protection. In the case of the filament, the electrical resistance generated by the filament was high, raising the environmental temperature and shortening the lifespan of the lamp. Accordingly, LED lighting fixtures using light emitting diodes (LEDs), which are economical due to low power consumption and miniaturization, and provide high visibility, have recently been developed and are widely used.

There are three main reasons why LED lighting fixtures do not turn on. This occurs when power from an external power source is not supplied to the LED lighting fixture due to a disconnection, etc., a malfunction occurs in the LED converter, or a malfunction occurs in the LED module.

Currently, diagnosis of malfunctions in LED lighting fixtures is mostly carried out by the user or manager removing the cover of the LED lighting fixture and then using a measuring instrument to check the cause of the malfunction or checking various parts of the LED lighting fixture one by one. However, this fault diagnosis method is not efficient and has the problem of requiring a significant amount of time for maintenance.

Accordingly, there is a need for a method to more quickly and accurately diagnose failures in LED lighting fixtures.

The power detection unit 141 detects the power of the external power source 150 supplied to the LED lighting fixture. In one embodiment, the power detection unit 141 may be a light emitting device that is turned on/off by power from the external power source 150. The power detection unit 141 displays the detection results of the power detection unit 141 in such a way that it emits light when power from the external power source 150 is supplied, and does not emit light when power from the external power source 150 is not supplied. You can. When power from the external power source 150 is not supplied to the LED lighting fixture due to a disconnection or power outage of the power cable connecting the external power source 150 and the LED lighting fixture, the power detection unit 141 is turned off and does not emit light. .

The usage time counter 142 counts the usage time of the LED lighting fixture. As an example, the usage time counter 142 can count the usage time of the LED lighting fixture by counting the time during which power from the external power source 150 is supplied to the LED lighting fixture, and the counted usage time is displayed externally through an indicator. It can be.

In addition, the counted usage time can be stored in memory so that the counted usage time is not reset even if a malfunction occurs in the LED lighting fixture. The usage time stored in the memory can be reset to the initial value upon the user's reset request, and if the LED module is replaced, the user can reset the usage time by pressing the reset button.

The user can diagnose a malfunction of the LED lighting fixture by checking the detection result of the power detection unit 141 displayed on the LED lighting fixture and the usage time counted by the usage time counter 142. After removing the cover of the LED lighting fixture, the user can check the detection result of the power detection unit 141 and the usage time counted by the usage time counter 142.

As an example, if the power detection unit 141 is not turned on, the user may determine that power from the external power source 150 is not supplied to the LED lighting fixture and that a malfunction has occurred in the LED lighting fixture. Accordingly, the user can resolve the malfunction by checking the power cable connecting the external power source 150 and the LED lighting fixture or checking for a power outage.

Alternatively, if the counted usage time exceeds the life time of the LED module 110, the user may determine that a failure has occurred in the LED module 110. Therefore, the user can solve the malfunction of the LED lighting fixture by replacing the LED module 110.

Alternatively, if the counted usage time is less than the life time of the LED module 110, the user may determine that a failure has occurred in the LED converter 120. Therefore, the user can solve the malfunction of the LED lighting fixture by replacing the LED converter 120.

As such, according to one embodiment of the present invention, the user does not need to use separate measuring equipment or check the components of the LED lighting fixture one by one, but counts the detection result of the power detection unit 141 and the usage time counter 142. By checking the usage time, you can quickly, efficiently and accurately determine the cause of the LED lighting fixture's failure, and take action accordingly. Accordingly, the time required for maintenance of LED lighting fixtures can be reduced.

Figure 2 is a diagram for explaining a fault diagnosis device according to another embodiment of the present invention.

Referring to FIG. 2, the failure diagnosis device according to an embodiment of the present invention includes not only a power detection unit 141 and a usage time counter 142, but also a first indicator 143, a failure determination unit 144, and a second indicator. (145) and the like may be further included.

As described above, the power detection unit 141 may detect the power of the external power source 150 supplied to the LED lighting fixture and display the detection result. Additionally, the usage time counter 142 counts the usage time of the LED lighting fixture, and the usage time counted by the usage time counter 142 may be displayed on the first indicator 143. As an example, the first indicator 143 may be an indicator that displays a number of 5 or more digits.

The failure determination unit 144 uses the counted usage time to determine that a failure has occurred in one of the LED converter 120 and the LED module 110 of the LED lighting fixture. The failure determination unit 144 determines that a failure has occurred in the LED converter 120 when the counted use time is less than the preset LED life time, and when the counted use time is greater than the LED life time, the LED module 110 ), it can be determined that a malfunction has occurred. If the LED usage time is less than the LED life time, the probability that the LED module is broken is low, so the failure determination unit 144 may determine that a failure has occurred in the LED converter 120.

Depending on the embodiment, the failure determination unit 144 may use not only the counted usage time but also the detection result of the power detection unit 141 to determine a failure of the LED lighting fixture. The failure determination unit 144 uses the counted usage time and the detection result of the power detection unit 141 to determine if a failure has occurred in one of the LED converter 120 and the LED module 110 of the LED lighting fixture or the external power supply. It can be determined that a malfunction has occurred in which power at (150) is not supplied to the LED lighting fixture. When the power detection unit 141 determines that power from the external power source 150 is not supplied to the LED lighting fixture, the failure determination unit 144 determines the external power source 150 according to the detection result of the power detection unit 141. ) It can be determined that a malfunction has occurred in which power is not supplied to the LED lighting fixture.

Meanwhile, as described above, the fault diagnosis device may be disposed on the control board 130, and since the fault diagnosis device is also deactivated when power from the external power source 150 is not supplied to the LED lighting fixture, an aspect of the present invention A fault diagnosis device or an LED lighting fixture according to an embodiment may include a battery so that a fault can be diagnosed even in a situation where power from an external power source is not supplied to the LED lighting fixture.

When power from the external power source 150 is not supplied to the LED lighting fixture, power from the battery is provided to the failure diagnosis device, so that the failure determination unit 144 can operate normally. When power from the external power source 150 is not supplied to the LED lighting fixture, the failure determination unit 144 supplies power from the external power source 150 to the LED lighting fixture, regardless of the detection result of the power detection unit 141. It can be determined that a malfunction has occurred.

The second indicator 145 displays the judgment result of the failure determination unit 144. The second indicator 145 may be a lamp that lights up in different colors, and the different colors indicate a failure of the LED converter 120, a failure of the LED module 110, and power from the external power source 150. It can respond to failures that are not supplied.

Additionally, the communication unit 146 may receive an on/off command of the LED module from the user terminal 310, and the LED lighting fixture may turn on or turn off the LED module according to the on/off command of the LED module. Alternatively, the communication unit 146 can control a group of LED lighting fixtures, for example, turn on/off all or part of the lighting, or control dimming.

The communication unit 146 may transmit at least one of the detection result of the power detection unit 141 and the counted usage time to the user terminal 310, and the user terminal 310 uses the counted usage time to determine the failure. As shown in (144), it may be determined that a failure has occurred in one of the LED converter 120 and the LED module 110 of the LED lighting fixture. In addition, the user terminal 310, like the failure determination unit 144, may determine that a failure has occurred in which power from the external power source 150 is not supplied to the LED lighting fixture according to the detection result of the power detection unit 141. .

For example, the user terminal 310 may be a smart device such as a smartphone or tablet PC, and the user may detect a failure of the LED converter, failure of the LED module, or failure of external power supply to the LED lighting fixture through an app on the smart device. You can check the fact that there is a malfunction.
