2, a method for controlling the operation of a plurality of LED modules is disclosed.

Referring to FIG. 2, a method of performing control on a group of a plurality of LED modules set by performing grouping on a plurality of LED modules included in the LED light is disclosed.

According to an embodiment of the present invention, the LED module group includes one of the LED module grouping (unlimited equal dimming) 200, the LED module grouping (limited equal dimming) 220, and the LED module grouping (unlimited differential dimming) 240. It can be determined based on the LED module grouping.

The LED module grouping (unlimited the same dimming) 200 has no limitation on the use of the LED modules in the LED module group, and is a grouping method in which the LED modules in the LED module group perform dimming with the same value. The LED module grouping (unlimited the same dimming) 200 may include a case where the LED modules are included in one group on the LED light and operate with dimming values less than the maximum brightness.

LED module grouping (limited equal dimming) 220 is a grouping method in which the use of LED modules in the LED module group is limited, and the LED modules in the LED module group perform dimming with the same value.

The LED module grouping (unlimited discrimination dimming) 240 is a grouping method in which there is no restriction on the use of the LED modules in the LED module group, and the LED modules in the LED module group perform dimming with different values.

Five LED modules in the LED module group (first LED module 270, second LED module 275, third LED module 280, fourth LED module 285 and fifth LED module 290) It can be assumed to exist. Under these assumptions, the LED module grouping (unlimited equal dimming) 200 has no limit on the use of all five LED modules in grouping, and the LED modules in the LED module group are ON with the same dimming value (for example, 50%). This is the case. LED module grouping (limited equal dimming) 220 has a limitation in use of some of the five LED modules (for example, the first LED module and the third LED module) in grouping, and LEDs within the LED module group This is the case when the module maintains the ON state with the same dimming value (for example, 50%). The LED module grouping (unlimited discrimination dimming) 240 has no limit on the use of all five LED modules in grouping, and the LED modules in the LED module group have different dimming values (for example, the first LED module 270). This is a case where the dimming value is 20% and the third LED module 280 maintains the ON state with a dimming value of 70%. The LED module's net value may be a brightness ratio assuming that the highest brightness is 100%.

LED module grouping used among LED module grouping (unlimited equal dimming) 200, LED module grouping (limited equal dimming) 220, and LED module grouping (unlimited differential dimming) 240 is a plurality of LED modules inside the LED light The lifespan score of 250 may be determined based on the importance of the lighting range 260 on the set LED installation environment.

For example, considering whether the differences in the life scores 250 of the plurality of LED modules are within a critical similar range, whether the differences in the life scores 250 of the plurality of LED modules are greater than or equal to the threshold difference range, the LED The grouping method of one of the module grouping (unlimited equal dimming) 200, the LED module grouping (limited equal dimming) 220, and the LED module grouping (unlimited differential dimming) 240 may be selectively used.

In addition, LED module grouping (unlimited discrimination dimming) 240 may be used in consideration of whether the importance 260 of the lighting range is relatively high on the set LED installation environment. When the importance 260 of the lighting range on the LED installation environment of the LED light is relatively high, the LED module grouping (unlimited discrimination dimming) 240 may be performed. The LED module grouping (unlimited discrimination dimming) 240 may be used when an illumination area to be illuminated through an LED light is required even with a small brightness. For example, when the range of illumination to be illuminated through the LED light is wide, the LED module grouping (unlimited discrimination dimming) 240 may be used. The LED module installed in the four-lane area may have a wider range of illumination to be illuminated through the LED light than the LED module installed in the two-lane area, and in this case, the LED module grouping (unlimited discrimination dimming) 240 is used to within the lighting range. Even if a small dimming value is used, it can be controlled to act as a lighting.

LED module grouping (unlimited equal dimming) 200, LED module grouping (limited equal dimming) 220, and LED module grouping (unlimited differential dimming) 240 on the LED light according to an embodiment of the present invention alternately You can use it to match the lifespan of the LED module similarly to increase the overall life of the LED light and to match the timing of the replacement of the LED module.

3 is a conceptual diagram showing a method for determining a life score of an LED module according to an embodiment of the present invention.

In Fig. 3, a method for determining the life score of an LED module is disclosed.

Referring to FIG. 3, the life score 300 of the LED module may be determined based on the ON state time 320 of the LED module and the dimming value 340 of the LED module.

The control unit of the LED light determines the life score 300 of the LED module based on the ON state time 320 of the LED module and the dimming value 340 in the ON state of the LED module, and the determined life score 300 of the LED module LED module grouping can be performed based on.

The lifetime score 300 of the LED module may be determined as A per hour when it is ON with maximum brightness, and when dimming, it may be determined as A * d per hour which is a product of an adjustment value d based on the dimming rate. For example, it is assumed that A is 1, and an adjustment value d based on a 50% dimming rate is 0.5. If a specific LED module operates for 2 hours at maximum brightness and then operates for 2 hours at a 50% dimming rate, the lifetime score 300 of the LED module is 2 days with 2+ (2 * 0.5) = 3 Can be. 0.5 is an example of an adjustment value (d) based on a 50% dimming rate.

The lifetime score 300 of the LED module can be accumulated. The lifespan score 300 of the LED module may be used as a value for predicting the remaining lifespan of the LED module as information on the usage of the LED module. In the present invention, the life score 300 of the LED module included in the LED light is maintained in a similar range to increase the life of the LED light and delay the replacement time.

The LED module group is determined based on the lifetime score 300 of the LED module, and control of the LED module may be performed based on the LED module group.

According to an embodiment of the present invention, LED module grouping (unlimited equal dimming), LED module grouping (limited equal dimming), and LED module grouping (unlimited differential dimming) are selectively performed to adjust the life score of the LED light within a critical similarity range. Can be.

According to an embodiment of the present invention, 1) LED module grouping (unlimited equal dimming) and LED module grouping (limited equal dimming) are used interchangeably in the first LED light installation environment and 2) second LED light In the installation environment, LED module grouping in which LED module grouping (unlimited differential dimming), LED module grouping (unlimited equal dimming), and LED module grouping (limited equal dimming) are used alternately may be performed.

Hereinafter, in the embodiment of the present invention, a specific LED module group setting method is disclosed.

4 is a conceptual diagram illustrating a method for setting an LED module group according to an embodiment of the present invention.

4, a method for setting a group of LED modules in an LED light including a plurality of LED modules is disclosed. Particularly, LED module grouping in which LED module grouping (unlimited equal dimming) and LED module grouping (limited equal dimming) are used alternately in the first LED light installation environment is disclosed.

Referring to FIG. 4, LED module grouping may be performed in consideration of LED environment information. The LED environment information may include illumination information around the LED light. The illumination intensity around the LED light may include information about the brightness around the LED light. The illumination intensity around the LED light may include information about the brightness around the LED light that changes over time.

First, in a time period in which the ambient illumination information is below a threshold, the entire LED module may operate at maximum brightness and LED module grouping may not be performed. Conversely, the LED module grouping may be performed because the entire LED module does not need to operate at the maximum brightness in a time period in which the ambient illumination information exceeds the threshold.

In the time period in which the LED module grouping is performed, the lifetime scores 400 of the plurality of LED modules are included in the critical similarity range 420, and the LED is preferentially installed under the LED light installation environment in which the LED module grouping (unlimited discrimination dimming) is not required. LED modules may be operated by grouping by module grouping (unlimited the same dimming) 440. In the case of an LED light including five LED modules as in the above example, the LED module group is a first LED module group (a first LED module, a third LED module, a fifth LED module), and a second LED module group. It may be set to include (second LED module, fourth LED module). Through the LED module group by crossing such that the life score 400 of the LED module included in the first LED module group and the life score 400 of the LED module included in the second LED module group are included in the similar threshold range 420. Light emission may be achieved.

Conversely, if the life score 400 of the current LED module is not included in the threshold similarity range 420 on a time period during which the LED module grouping is performed, the LED module is grouped based on the LED module grouping (limited equal dimming) 460 This can work.

Specifically, two LED module operation controls may be performed according to differences in life scores between LED modules. When the difference in the life score between the LED modules is greater than or equal to the threshold difference value, the control is performed in the priority mode of the low-use LED module, grouped based on the LED module grouping (limited equal dimming) 460, and the LED module may operate. If it is less than the threshold difference value, the LED module may be operated by grouping again based on the above-described LED module grouping (unlimited equal dimming) 440.

The low-use LED module used in the LED module grouping (limit equal dimming) 460 preferential use mode uses the low-use LED module with a relatively low life score grouped separately, and the high-use LED module with a relatively high life score is It may be a mode in which the lifetime scores of a plurality of LED modules are matched in an unused manner.

That is, in the embodiment of the present invention, in the first LED light installation environment, the LED module grouping (unlimited equal dimming) 440 and the LED module grouping (limited equal dimming) 460 are used alternately, so that the life score of the LED module is It can be adjusted to be included in the critical similarity range.

5 is a conceptual diagram illustrating a method for setting a group of LED modules according to an embodiment of the present invention.

5, a method for setting a group of LED modules in an LED light including a plurality of LED modules is disclosed. In particular, LED module grouping in which the LED module grouping (unlimited differential dimming), LED module grouping (unlimited equal dimming), and LED module grouping (limited equal dimming) are used alternately in the second LED light installation environment is disclosed.

Referring to FIG. 5, first, the entire LED module may operate at the maximum brightness in a time period in which the ambient illumination information is below a threshold, and grouping of the LED modules may not be performed. Conversely, the LED module grouping may be performed because the entire LED module does not need to operate at the maximum brightness in a time period in which the ambient illumination information exceeds the threshold.

When the lifetime scores 500 of a plurality of LED modules are included in the critical similarity range 520 on a time interval during which the LED module grouping is performed, the LED module grouping (unlimited discrimination dimming) according to the range of the ambient illuminance value 540 ( 560), LED module grouping (unlimited the same dimming) 550 may be used selectively. When the ambient illuminance value 540 is in the first range, the LED module grouping (unlimited equal dimming) 550 is used, and when the ambient illuminance value 540 is in the second range, the LED module grouping (unlimited discrimination dimming) 560 can be used. The second range may be greater than the first range. That is, the LED module grouping (unlimited equal dimming) 550 is used on a relatively dark time period, and the LED module grouping (unlimited discrimination dimming) 560 is used on a relatively dark period to reduce energy used in the LED module. You can save.

When the LED module grouping (unlimited discrimination dimming) 560 is performed, the life scores of the LED modules on the LED light may be changed from each other. In this case, the usage time of the LED group performing the LED module grouping (unlimited discrimination dimming) 560 is adjusted to include the life score of the LED module in a critical similarity range, or the LED module grouping (limited equal dimming) 580. Through this, the life score of the LED module on the LED light can be included in the critical similarity range.

For example, if the lifetime score 550 of the LED module on the LED light exceeds the critical similarity range 520, the LED module grouping (unlimited discrimination dimming) 560 or the LED module grouping (limit equal) according to the ambient illumination value Dimming) 580 may be optionally used.

When the ambient light value is in the second range, the LED module grouping (unlimited discrimination dimming) 560 is used, and when the ambient light value is in the third range, in the second range, the LED module grouping (limited equal dimming) ) 580 may be used. The third range may be greater than the second range. That is, the LED module grouping (unlimited differential dimming) 560 is used on a relatively dark time period, and the LED module grouping (limited equal dimming) 580 can be used on a relatively dark period. Through this method, the brightness of the LED module can be adjusted to the critical similarity range more quickly by considering the relatively less range of illumination to be illuminated through the LED light.

7 is a conceptual diagram illustrating a method for cross-control of LED lights in an LED group.

Referring to FIG. 7, in performing control of LED lights in an LED group, a method for efficiently utilizing an illumination range by performing control alternately is disclosed.

If the LED group is the first LED light installation environment and performs the same dimming limit, all the LED lights in the LED group do not perform the same dimming limit for the same LED module, and use the different LED modules to cross the same limit By performing dimming, lighting of the LED light included in the LED group can be performed more effectively within the same area.

The LED group may be divided into a plurality of lower LED groups according to the LED installation environment. For example, the LED group may be divided into a plurality of sub-LED groups according to the LED installation environment so that adjacent LED lights are not included in the same sub-LED group.

Each of the plurality of lower LED groups may perform unlimited identical dimming and limited identical dimming for different LED modules. For example, when the first lower LED group 710 and the second lower LED group 720 exist, and the first lower LED group 710 and the second lower LED group 720 perform unlimited identical dimming, The LED light included in the first lower LED group 710 uses a first LED module and a third LED module, and the LED light included in the second lower LED group 720 includes a second LED module and a fourth LED module. Can be used.

Thereafter, when performing the same dimming of the limit, the LED light included in the first sub-LED group 710 uses a second LED module and the fourth LED module, and the LED light included in the second sub-LED group is the first LED. A module, a third LED module, and a fifth LED module can be used.

In this way, by using different LED modules of adjacent lights, it is possible to enable lighting of the entire area while using a small amount of power.

In this way, the control of the LED lights included in the same LED group is performed on the basis of different LED modules, so that it is possible to solve the part where the lighting of some areas can be darkened due to dimming of the LED modules.

In the second LED light installation environment, the LED lights are alternately using the LED module grouping (unlimited differential dimming), the LED module grouping (unlimited equal dimming), and the LED module grouping (limited equal dimming). Adjust the life score of the LED module to the critical similarity range,
The second LED light installation environment is an LED light, characterized in that the environment in which the importance of the lighting range is relatively higher than the first LED light installation environment. The method of claim 5,
When the life scores of the plurality of LED modules in the second LED light installation environment exceed a threshold similarity range, the LED light groups the LED modules (unlimited discrimination dimming) or groups the LED modules in consideration of an ambient light value. LED light characterized by using (limited equal dimming) selectively.
