Description

TECHNICAL FIELD [0001] The present invention relates to a TV lighting control device,

And more particularly, to an apparatus and method for controlling illumination mounted on the back of a TV for protecting eyesight.

Unless otherwise indicated herein, the contents set forth in this section are not prior art to the claims of this application and are not to be construed as prior art to be included in this section.

Modern eyes are exposed to various light stimuli such as TV, computer, neon sign, smart phone. Especially, modern people mostly watch TV almost every day. The television image is generated when electrons generated in the electron layer are imprinted on the fluorescent material of the cathode ray tube and are photographed, which is similar to the emission principle of a fluorescent lamp. Therefore, watching television is like gazing at a fluorescent lamp itself. For this reason, eyes are tired when you watch TV for a long time. If you turn off the lights and darken the surroundings and watch the TV, the brightness difference between the surroundings of the cathode-ray tube, which the eyes mainly observe, increases, and the eye fatigue becomes worse.

In particular, research has shown that watching a red-tinted TV screen increases the possibility of becoming a farsighted myopia by imposing a burden on the ability of the eye.

Most of all, you can watch TV before you go to sleep with your TV turned off. It can cause a lot of eye fatigue because of the contrast between dark ambient lighting and bright TV screen illumination.

1 is a view showing an embodiment of utilization of a TV lighting control device.

Referring to FIG. 1, a lighting control apparatus according to an exemplary embodiment of the present invention detects brightness, color space, color temperature, and ambient illuminance of a TV illuminated on a TV screen, And so on. For example, the lighting control device controls lighting details such as the color of light emitted from the mood or the like mounted on the back of the TV, the illumination time, the brightness of the vision protection illumination, and the number of LED lamps to be operated. Thus, as shown in FIG. 1, even when the surroundings of the TV are dark, the brightness of the surroundings is adjusted by the sight protection light and the mood provided on the back of the TV, thereby protecting the eyesight and reducing the fatigue of the eyes.

2 is a diagram showing an example in which a lighting apparatus is installed in a TV.

2, a vision protection illumination control signal receiving unit 11, a mood control signal receiving unit 12, and a TV control signal receiving unit 13 may be installed on the front surface of the TV. The vision protection illumination unit 14 and the mood illuminator 15 may be installed. The vision protection illumination unit 14 and the mood light 15 are spaced apart from the edge of the back panel of the TV at regular intervals. However, the method of installing the vision protection illumination 14 and the mood light 15 is not limited to the illustrated example.

The vision protection illumination control signal receiving unit 11 and the mood lighting control signal receiving unit 12 receive the illumination control signal from the remote controller. In the embodiment, when the TV power is on, it automatically controls the vision protection illumination and the mood through the TV screen and the recognition of the surrounding brightness.

If the user turns off the automatic lighting control function, it is possible to control the operation of the vision protecting illumination unit, the mood, etc., the color temperature, the illuminance, and the light amount, respectively, even when the TV is powered on.

3 is a block diagram showing a configuration of a lighting control apparatus according to the embodiment.

Referring to FIG. 3, the TV lighting control apparatus may include a sensor module 110, a lighting control module 130, a vision protection illumination unit 150, and a mood light 170. The term " module ", as used herein, should be interpreted to include software, hardware, or a combination thereof, depending on the context in which the term is used. For example, the software may be machine language, firmware, embedded code, and application software. As another example, the hardware may be a circuit, a processor, a computer, an integrated circuit, an integrated circuit core, a sensor, a micro-electro-mechanical system (MEMS), a passive device, or a combination thereof.

The sensor module 110 senses the illuminance of the light irradiated on the TV screen and the illuminance of the TV. For example, the sensor module 110 detects illuminance, brightness, light amount, color temperature, color space information (RGB, YUV, YCbCr, YPbPr, etc.) of light irradiated on the TV screen. The sensor module 110 can detect detailed information on the light to be illuminated by the TV screen, which changes every time the channel is changed.

The lighting control module 130 controls the lights mounted on the rear panel of the TV according to the details of the light irradiated from the TV screen detected by the sensor module 110 and the illuminance around the TV. For example, the illumination control module 130 can control details such as illumination, illumination, brightness, color temperature, color space information, lighting time, etc. of each of the vision protection illumination and the mood.

The eye protection light 150 is a light for vision protection provided at a plurality of spaced apart portions on the rear side of the TV. In an embodiment, the vision-protected illumination 150 may be comprised of several LED lights. The sight protecting illumination 150 may be configured such that the illumination details including illumination time, brightness, and light amount are automatically controlled by the illumination control module 130, or illumination details are controlled even when the TV power is turned off by the remote controller .

In the embodiment of the present disclosure, a plurality of LED lights are installed on the rear panel of the TV, so that the lighting information of the TV screen and the surrounding environment And can be finely controlled by the illumination information. For example, the mood illuminant 170 may automatically adjust illumination detail control information including color, illumination time and brightness according to light information irradiated on the TV screen sensed by the sensor module 110.

4 is a block diagram showing a more detailed configuration of a lighting control apparatus according to the embodiment.

4, the sensor module 110 may include a color space sensing unit 111 and a brightness sensing unit 113. The lighting control module 130 may include a color space control unit 131 and a brightness control unit And a control unit 133, as shown in FIG.

The color space sensing unit 111 senses color space information including YUV, YCbCr, YPbPr, and the RGB change due to the light irradiated on the TV screen.

The brightness sensing unit 113 senses light emitted from the display surface of the TV and illumination and luminosity near the TV.

The color space controller 131 controls a color change such as a mood of a color included in a color space within a certain range from the color space sensed based on the color space sensed by the sensor module 110. For example, when a green object is displayed on a TV screen and a color space of cyan (G) is detected, a mood or the like is controlled by a color similar to the sensed color space, or a mood Can be controlled.

The illumination brightness control unit 133 controls the brightness, the irradiation time and the mood of the mood lighting unit 150 and the illumination of each of the eyesight protection lights according to the illuminance of the TV screen and the illuminance and brightness of the surroundings of the TV . For example, the illumination brightness control unit 133 can control the total sum of the illuminance of the light irradiated on the TV screen, the illuminance and the mood of the vicinity of the TV, and the illuminance of the light irradiated by the sight protecting illumination unit 150 to be less than a predetermined level . Specifically, the illumination brightness controller 133 sets the illuminance in the vicinity of the TV as the reference illuminance, acquires the recommended illuminance value with respect to the reference illuminance value from the memory, and adjusts the illuminance and the mood of the illuminated light on the TV screen, It is possible to control so that the total sum of the illuminance of the light irradiated by the light source 150 does not exceed the recommended illuminance value. The recommended illuminance values may be stored as standard values matched based on illumination values near the TV, color temperature, or may be adjusted by user settings.

In an embodiment, the lighting control module 130 may be operable to filter the blue light that occurs upon watching the TV. For example, the lighting control module 130 selects colors of a color space capable of canceling a blue light (a blue light source) generated on a TV screen at a preset night time, So that the blue light can be filtered. For example, the lighting control module 130 converts the color space of the light irradiated on the TV screen based on HSV (Hue Saturation Value). The HSV color space is a color space composed of colors (Hue, H), saturation (S), and brightness (Value, V). Here, the value of the color (H) can be calculated separately from the saturation and brightness. In addition to the color space, there are a number of color spaces such as RGB, CMYK, and YUV, but HSV will be described in this embodiment as an example.

The illumination control module 130 converts the color of light emitted from the TV screen into the HSV color space, and then, when it is detected that the light located in the color space of the blue color series is irradiated, Select an existing color space. For example, if a complementary color in a Munsell color space is defined as a complementary color, and a complementary color defined in Munsell is represented in an H region, the complementary color of the blue color is red in one embodiment. That is, a color space having a complementary color relationship can be selected from the H value. Then, by causing the mood light 170 to illuminate the colors included in the selected color space, the blue color light generated in the TV screen is canceled by white due to the complementary color contrast, thereby filtering the blue light (blue light source) .

Hereinafter, the lighting control method will be described in turn. Since the function (function) of the lighting control method according to the present invention is essentially the same as the function of the lighting control device, a description overlapping with those of Figs. 1 to 4 will be omitted.

5 is a flowchart showing a data processing flow of the lighting control apparatus according to the embodiment.

In step S510, the sensor module 110 detects details of the light illuminated on the TV screen. Specifically, the illuminance and brightness of the illuminated light are detected on the changed screen every time the TV channel is changed, and the illuminance and the brightness change due to the screen changed according to the program streamed in one channel are detected.

In step S520, the sensor module 110 detects the ambient illuminance of the TV. For example, in step S520, illumination change due to lighting on / off of the space where the TV is installed and illuminance due to natural light can be detected.

In step S530, the sensor module 110 detects the color space and the color temperature of the light irradiated by the TV screen.

In step S540, the control module 150 controls the illumination for vision protection according to the ambient brightness information and the brightness and color temperature information of the TV screen.

In step S550, the control module 150 controls the mood according to the surrounding brightness information and the brightness and color temperature information of the TV screen. For example, in step S550, the color temperature, color space information, and operation time of the mood and the like can be controlled according to the sensed ambient illuminance and the color space sensing information of the light illuminated by the TV screen.

The illumination control apparatus and method as described above can reduce the eye fatigue even when watching TV at night by automatically controlling the illumination and mood of the eyesight by sensing the change in illumination intensity and color temperature and color space due to the ambient illumination and the TV screen . In addition, the mood mounted on the back of the TV and the lighting for vision protection enable the TV to be used as a lighting device.
