However, if there is a functional similarity and an equivalence thereof, the modified structure can be regarded as an equivalent structure. In addition, reference numerals added to respective components are described for convenience of explanation.

1 is a control conceptual diagram of a lighting control apparatus according to the present invention. The illumination control apparatus may include an input unit 100, a mode switching unit 200, a storage unit 300, a control unit 400, and an output unit 420.

The control unit 400 receives a signal from the input unit 100 and the mode switching unit 200 and receives power from the power source 410. The output unit 420 refers to the brightness profile stored in the storage unit 300, Lt; RTI ID = 0.0 > controllable < / RTI > The output unit 420 is configured to adjust power to a plurality of lighting devices in accordance with a control signal.

The input unit 100 is configured to generate an illumination control signal from a user's operation and transmit the generated illumination control signal to the control unit 400. The input unit 100 may include an individual adjustment unit 110, a block adjustment unit 120, and a master adjustment unit 130.

The individual adjuster 110 may be configured to receive input from a user's operation to individually adjust each lighting device, such as the first lighting device 10 or the second lighting device 20. [

The block adjusting unit 120 may be configured to include a plurality of illumination blocks including at least one illumination device among a plurality of illumination devices, and receive input by a user's operation to adjust the brightness of each illumination block.

The master control unit 130 may be configured to receive input by a user's operation in order to collectively adjust the brightness of a plurality of lighting apparatuses.

The mode switching unit 200 may be configured to generate a mode signal for switching modes such as daytime, nighttime, and nighttime illumination of the lighting apparatus. The brightness of the plurality of illumination devices can be changed corresponding to the ambient brightness condition. The mode switching unit 200 may be configured as a switch capable of switching to three modes. The brightness of the lighting device required varies depending on each mode, and the luminance is required to be the highest in the daytime and the lowest luminance in the nighttime. Therefore, the mode switching unit 200 can be configured to generate three signals according to the selection of the pilot. Meanwhile, the configuration of the mode switching unit 200 is merely an example, and various modes can be changed.

The storage unit 300 stores a brightness profile according to the power applied to each illumination device. At this time, the generated brightness profile can be stored by measuring the actual brightness according to the applied power. The storage unit 300 is configured to be able to add, delete, and update a profile according to brightness so that the changed profile can be updated when the lighting device is replaced.

The control unit 400 receives the illumination adjustment signal from the input unit 100 and generates an output signal for controlling the power applied from the output unit 420 based on the brightness profile of the storage unit 300. The control unit 400 may control the output unit 420 such that different power is applied to each lighting apparatus such that each lighting apparatus has the same luminance. The function of the control unit 400 will be described in detail with reference to FIG.

The output unit 420 is configured to apply power to each illumination device, and is configured to be capable of adjusting the power applied to each illumination device by receiving a plurality of output signals. The adjustment of the applied power can be configured to adjust the voltage applied to the illumination device or to adjust the applied current. Each output 420 may be configured to be connected to a potentiometer (not shown) to control the output, and in such a configuration, the voltage applied to each lighting device can be varied. However, the configuration in which a plurality of output units are provided to adjust the power applied to each illumination device is merely an example, and can be applied to various configurations for controlling power.

Meanwhile, the illumination control method according to the present invention may include a profile storage step, an illumination control signal input step, an output signal control step, and an output control step of adjusting an applied power, May be provided.

The profile storing step may be configured such that each brightness profile corresponding to the power applied to the plurality of lights is stored.

In the step of receiving the illumination control signal, the illumination control signal may be received from the input unit such that at least one of the plurality of illumination devices is controlled to have a predetermined brightness.

The step of controlling the output signal includes receiving the illumination adjustment signal and controlling the output signal so that power corresponding to a predetermined brightness is applied to the plurality of illumination devices using the brightness profile information.

The output adjustment step of adjusting the applied power may be configured to receive the output signal and adjust the power applied to the plurality of illumination devices, respectively.

Hereinafter, the brightness profile will be described with reference to FIG. FIG. 2 is a view showing a part of an illumination device in an aircraft cockpit. FIG.

As shown in the figure, a plurality of illuminating devices may be provided inside the cockpit, and a plurality of instrument panels may be included. Fig. 2 (a) shows a state in which four instrument panels are provided.

The pilot of the aircraft watches such a plurality of instrument panels and can recognize the flight information from this.

A plurality of instrument panels constituting such an illumination device may have different brightness profiles depending on the power applied according to the manufacturer. In order to maintain the pilots' perception of flight information so that the pilot does not concentrate or lose sight at a particular occasion, the pilot's visual sensory uniformity should be maintained. That is, the difference in brightness between the peripheral illumination device and the surrounding illumination device should be hardly felt. To this end, as a minimum quantitative criterion, each lighting device is required to have a brightness difference of at least twice that of an ambient lighting device.

Each instrument panel emits light in a variety of ways. The scales and the guides can emit light by themselves, and the light is provided on the back surface of each scale to allow light to pass only through the light transmitting area. Depending on the size of the eye, the number of scales, the number of instructions, etc., each instrument panel may have the same brightness quantitatively and visually different brightness. In FIG. 2 (a), the first dashboard 510 and the second dashboard 520 are shown in a similar form, but the intervals of the scales provided in each dashboard are different. Accordingly, even if the two instrument panels have the same light emitting portion and the same power is applied, the brightness of the second instrument panel 520 having a larger scale becomes brighter. Therefore, the second instrument panel 520 may be emphasized to the pilot. In addition, as shown in FIG. 2 (b), different types of instrument panels and screens may be provided in each block, and the arrangement thereof may be different, so that the difference in brightness experienced by the pilot may be large.

On the other hand, the brightness profile can be stored as a brightness change of the lighting device according to the change of the voltage, and also can be stored as the brightness change of the lighting device according to the change of the current.

The storage unit 300 stores information as a basis for controlling brightness of a plurality of illumination devices. The storage unit 300 stores the brightness profile from the minimum brightness to the maximum brightness according to the power applied to the illuminator. At this time, a profile previously created by an external device can be stored.

On the other hand, when a plurality of lighting apparatuses are to be replaced, the information of the brightness profile may also be exchanged. Various methods of data processing can be performed, and therefore, a detailed description thereof will be omitted.

2B, the cockpit may include a front block 610, a side block 620, and a right block 630, and each block may include a lighting device such as a screen or the like Lt; / RTI >

The plurality of blocks can be classified and arranged according to the kind of specific information represented by the instrument panel. The pilot needs to lighten or darken the lighting device for each block as needed during piloting. In other words, when there is a need to selectively recognize the information of the instrument panel arranged in a specific block rather than the information displayed in the lighting apparatus in another block, the brightness can be adjusted for each block.

At this time, the plurality of illumination devices belonging to one block may be controlled to be controlled using the brightness profile stored in the storage unit 300 so as to have the same brightness even if the brightness is adjusted. Even if the block includes a screen or a different type of illumination device, the information stored in the brightness profile can be used to maintain the brightness uniformity.

Although not shown, in the case of an illumination device provided in an aircraft cockpit, a signal light, a primary light, a floodlight, an electronic color / monochromatic display device Display, Individual / Secondary Lights, and the like. The signal light operates at three levels of brightness: daytime, nighttime and nighttime. The daytime is the highest brightness. The nighttime light is the lowest latitude. It consists of a warning light, a warning, etc. . Primary light is instrument and panel backlighting. It is used only at night and can be individually controlled by dividing into instrument panel area and block. A floodlight is a lighting device that illuminates the entire cockpit area, is used only at night, and can be configured for individual control by dividing it into instrument panel areas and blocks. The electronic color / mono display is a backlighting device for a vision panel, which corresponds to a digital instrument and can be connected to most avionics systems. Individual / Secondary Lights include convenience lighting devices such as reading lights, guidance lights, and the like. However, the type, number, arrangement, etc. of the instrument panel, screen, and block may be variously modified, and thus the brightness profile may be variously changed.

Hereinafter, the function of the control unit 400 will be described in detail with reference to FIG.

Referring to FIG. 3, different brightness profiles are shown for the voltages of the three lighting devices. Each illumination device may have a different light-transmitting area, reflection area, light-emitting area, etc., and the profile may vary due to various factors such as the type of light-emitting device.

The illumination device A has a profile that is close to linear, the illumination device B has a sudden brightness change near the minimum brightness and the maximum brightness, and the lighting device C has a sudden change near the maximum brightness. Therefore, the voltage for generating the same luminance L1 is VB1 <VA1 <VC1. At this time, the voltage having the uniform brightness of the brightness of the lighting devices A, B and C is VA2 <VB2 <VC2, and the voltage difference for changing L1 to L2 is VC <VA <VB.

In the case where such a brightness profile is stored, when a master signal that changes the brightness of a plurality of lighting devices from L1 to L2 has been received, the control unit 400 controls the potentiometers (A, B, C) The control signal is generated so that the resistance values of A, B, and C are changed corresponding to VA, VB, and VC.

When the controller 400 receives the block adjusting signal, the controller 400 may generate a control signal for changing a resistance value of a potentiometer (not shown) connected to the lighting device corresponding to each block.

On the other hand, the pilot is configured to independently adjust the brightness of the specific instrument panel to increase the recognition of the instrument panel. The control unit 400 may be configured to receive a signal for selecting an illumination device to be individually controlled among the adjustment devices and a control signal for changing a resistance value of a potentiometer (not shown) connected to the illumination device .
