A perspective view schematically showing goggles.

As shown in the figure, the sunglasses 100 to which the power-saving sleep mode control method according to the present invention is applied comprises a sunglasses frame 110 and an optical characteristic adjustment system 120 for sunglasses.

The sunglasses 100 may select the color of the lenses 121a and 121b and automatically adjust the light transmittance by the optical characteristic adjusting system 120.

The sunglasses frame 110 is rotatably hinged to both ends of the body portion 111 and the body portion 111 positioned in front of the wearer's eyes when worn, respectively located on the left and right of the wearer's head when worn It consists of the 1st and 2nd leg parts 112a and 112b.

The optical characteristic adjusting system 120 includes lenses 121a and 121b, a controller 122, a sensor unit (not shown), a temperature sensor 123a, and a wear sensor 123b fixed to the main body 111. And an illumination intensity sensor 123c, a function selection unit 124, a state display unit 125, a lens driving unit 126, a light source unit 1261a, a power supply unit 127, and a charging unit 128.

The lenses 121a and 121b installed on the main body 111 are made of an LCD panel 1211, and the LCD panel 1211 is made of a shutter LCD that is capable of adjusting light transmittance by a magnitude of a driving voltage. It is formed of a plastic LCD with a solid material.

Here, the magnitude of the driving voltage applied to the LCD panel 1211 to adjust the light transmittance is adjusted by the lens driver 126. In this case, when the LCD panel 1211 is applied to the sunglasses 100 or the goggles 200, polarizing films (not shown) are respectively installed on both sides thereof, and a diffusion type color filter (not shown) is disposed in place of the polarizing film. And a harmful light filter (not shown).

The control unit 122 is in the form of a microcomputer (not shown) including a memory device (not shown) in which a control program is stored and a central processing unit (CPU: not shown) for executing the control program. In addition, the controller 122 receives power from the power supply unit 127.

Here, the sensor unit includes a temperature sensor 123a, a wear sensor 123b, and an illumination sensor 123c.

The temperature sensor 123a detects the ambient temperature, transmits the detected ambient temperature data to the controller 122, and the mall wear sensor 123b detects whether the sunglasses 100 or the goggles 200 are worn. In addition, the sensor transmits information on whether it is worn, and the illumination sensor 123c detects ambient illumination and transmits the detected ambient illumination data to the controller 122.

As described above, the data and information sensed by the temperature sensor 123a, the wear sensor 123b, and the illuminance sensor 123c are input to the controller 122.

In this case, the controller 122 receives function selection information such as automatic adjustment of concentration and manual adjustment from the function selection unit 124.

The control signal is output to the lens driver 126 according to various data and information input through the sensors 123a, 123b, and 123c, and the present state of the sunglasses 100 or the goggles 200 is displayed on the status display unit 125. Print information about the status.

The lens driver 126 includes a light source driver 126a and a shutter LCD driver 126b. The lens driver 126 receives a control signal from the controller 122 and drives the LCD panel 1211 and the light source unit 1261a accordingly.

The light source driver 126a causes the light source unit 1261a to emit a light source of a selected color based on a control signal input from the controller 122.

The shutter LCD driver 126b adjusts the operating voltage so that the LCD panel has an appropriate light transmittance (concentration) based on the control signal input from the controller 122.

Here, the shutter LCD driver 126b generates an operating voltage having a frequency of 36 Hz (preferably 1 Hz or less) to reduce power consumption.

In addition, the controller 122 receives power from the power supply unit 127 and a separate external power source 129 provided by the controller 122. In this case, the power supply unit 127 supplies power to the control unit 122, the lens driving unit 126, etc. For this purpose, the power supply unit 127 is preferably made of a rechargeable battery, but to the power supply unit 127 Instead of the secondary battery, a primary battery may be applied, and the power supply unit 127 may be formed of solar cells 130a and 130b, but is not limited thereto.

The charging unit 128 is controlled by the control unit 122, so that the charging of the power supply unit 127 from the external power source 129 is made stable.

The operation process of the sunglasses having the structure as described above will be described.

First, the display of the setting and the state is made regardless of the wearing state (S10). In this step, the remaining amount of battery is displayed through the status display unit 125.

Then, whether the wear is detected by the wearing sensor 123b, the result is transmitted to the control unit 122, and the control unit 122 determines the wearing state by determining whether to wear (S20).

Here, in the non-wearing state, the display step (S10) for the setting and the state is performed again, and in the case of the wearing state, the process for concentration adjustment (light transmittance adjustment) and color selection is performed at the same time.

First, the concentration control process will be described. The concentration adjustment process includes the function selection check step (S31), the illuminance / temperature change check step (S31a), the illuminance / temperature compensation step (S33), the concentration variable value output step (S34), the LCD panel driving step (S35), and the basic concentration. A value output step S32b is included.

The function selection confirmation step S31 is a step of confirming whether the user has selected the automatic concentration control function, and is performed through the function selection unit 124.

If the automatic density control function is not selected, the basic concentration value output step S32b is performed, and the basic concentration value output step S32b is performed by the shutter LCD driver so that the controller 122 outputs the preset basic density value. A control signal is output to 126b.

At this time, the basic concentration value may be manually selected as three or more steps (bright, medium bright, dark). After the basic concentration value output step S32b, the LCD panel driving step S35 is performed.

If the automatic concentration control function is selected, the illuminance / temperature change check step S32a is performed afterwards, and the illuminance / temperature change check step S32a is performed by the controller 122 to detect the temperature sensor 123a and illuminance. This is done by receiving the relevant signal from the sensor 123c and determining that the current illuminance and / or temperature is different from the previous one.

At the time of the automatic concentration adjustment, three or more levels of automatic concentration adjustment are possible. At this time, the light transmittance may be set in steps from 3.2% to 65%. If a difference occurs in at least one of illuminance and temperature, the illuminance / temperature compensation step S33 is performed. The illuminance / temperature compensation step S33 is achieved by the controller 122 calculating a new control value for compensating for the different illuminance and / or temperature.

Here, before determining the peripheral illuminance, the control unit 122 determines the signal input to the illuminance detecting sensor 123c to compensate the concentration of the lenses 121a and 121b by the corresponding illuminance, and the LCD is composed of a shutter LCD. The panel 1211 changes the blocking concentration and the reaction time according to the temperature.

That is, as the temperature is lowered, the blocking concentration and reaction rate of the LCD panel 1211 are also lowered. In order to obtain a desired level of concentration and reaction rate at the LCD panel 1211, compensation for temperature is required. Illumination / temperature compensation step (S33) is made.

In the concentration variable value output step S34, the control unit 122 outputs a control signal to the shutter LCD driver 126b based on the compensated illuminance / temperature data, and in the illuminance / temperature change check step S32a. If there is no change in both illuminance and temperature, the step of outputting the variable concentration value S34 is immediately performed.

The shutter LCD driving step S35 is performed by the concentration shutter LCD driver 126b applying a driving voltage to the LCD panel 1211.

Next, the process of color selection is demonstrated. The color selection process includes a step S41 of checking whether a color is selected, a selected color output step S42a, a basic color output step S42b, and a color filter driving step S43.

The step of checking whether the color is selected (S41) is a step of checking whether the user has selected a desired color, and is performed through the function selection unit 124. If the color is not selected, the basic color output step S42b is performed, and the basic color output step S42b sends a control signal to the light source driver 126a such that the controller 122 outputs a preset basic color. Output

If the color is selected by the wearer, the selective color output step S42a is performed, and the selective color output step S42a is performed by the control unit 122 so that the light source unit 1261a irradiates the color selected by the wearer. A control signal is output to 126a, and the color filter driving step S43 is performed by the light source driver 126a applying a driving voltage to the light source unit 1261a according to the control signal from the controller 122.

On the other hand, after the user wears sunglasses or goggles describes the process of switching to the power-saving sleep mode according to the non-use.

First, the setting and the state of the sunglasses 100 or the goggles 200 are displayed (S51). At this time, the display of the setting and the state is made regardless of the wearing state of the sunglasses 100 or the goggles 200.

Then, it is detected whether the sunglasses 100 or goggles 200 are worn (S52). In this case, whether the sunglasses 100 or the goggles 200 are worn is detected by the wearing sensor 123b (S52-1), and the result is transmitted to the controller 122 (S52-2). The wearing condition is automatically detected by 122 determining whether to wear.

In addition, when the controller 122 determines that the sunglasses 100 or the goggles 200 are not worn according to the data detected by the wearing sensor 123b, the control unit 122 switches to the power saving sleep mode (S58).

However, when the controller 122 determines that the user wears the sunglasses 100 or the goggles 200 according to the data detected by the wearing sensor 123b, the vicinity of the sunglasses 100 or the goggles 200 is determined. The illuminance is detected (S53). That is, when the user wears the sunglasses 100 or the goggles 200, the ambient light sensor 123c detects the ambient light (S53-1), and the data detected by the light sensor 123c controls the controller. It is transmitted to 122 (S53-2).

At this time, the controller 122 compares whether the illuminance data detected by the illuminance sensor 123c is equal to or greater than the reference illuminance or less than the reference illuminance, and determines that the dark condition is less than or equal to the reference illuminance. S58).

That is, after determining the wearing state of the sunglasses 100 or the goggles 200 and the magnitude and the change amount of the signal input to the controller 123 from the illuminance sensor 123c by the microcomputer (not shown) of the controller 122, the signal If the size of is less than 50 Lux, or if the intensity variation of ± 50 Lux does not occur between 10 and 120 minutes, it is determined that the sunglasses 100 or the goggles 200 do not need to operate, and the driving supplied to the circuit At the same time, the current is cut off (S58-1) and the mode is switched to a power saving sleep mode to minimize power consumption (S58-2).

In this case, when the user grips the first and second leg portions 112a and 112b of the sunglasses 100 and rotates around the main body 111, the user wears the sunglasses 100. Recognizes and proceeds to the next step and driving mode, but when the first and second leg portions 112a and 112b of the sunglasses 100 are gripped and rotated around the main body 111, or at first When the first and second leg parts 112a and 112b are kept in a folded state, the first and second leg parts 112a and 112b are entered and switched to the power saving sleep mode (S58).

On the other hand, the controller 122 compares the illuminance data input from the illuminance sensor 123c with the reference illuminance 50 Lux, and when it is determined that the detected illuminance is brighter than the reference illuminance, the illuminance sensor 123c is determined. Illumination data according to the surrounding environment and the situation detected through the input to the control unit 122 in real time.

In this way, the ambient light sensor 123c detects the ambient light change in real time and continuously (S54), and the signal size (50 Lux) and the change amount (± 50 Lux light change between 10 to 120 minutes) according to the ambient light. Detects and transmits to the control unit 122 (S54-1), and if the illumination data is input to the control unit 122 in real time and continuously, the control unit 122 determines whether there is a change in illuminance and then determines that there is no change in the illuminance. In this case, a power saving sleep mode is switched (S58).

At this time, the illuminance sensor 123c detects the magnitude and the change amount of the signal according to the ambient illuminance and transmits it to the controller 122 (S54-1).

If it is determined that there is a change in the illuminance data continuously input after being detected by the illuminance sensor 123c, the controller 122 according to the ambient environment and the situation, the sunglasses 100 or the goggles ( Is installed in the 200, while switching to the driving mode (S57) while controlling the density (S55) and color (S56) of the LCD panel 1211 made of a flexible shutter LCD provides a suitable environment for the wearer.

Since the control of the density and color of the LCD panel 1211 has been described above, it will be omitted below.

Meanwhile, the wearer of the sunglasses 100 or the goggles 200 may arbitrarily select the switching to the driving mode or the power saving slim mode and the non-switching mode. That is, when the user is using the sunglasses 100 or goggles 200, but the situation can be recognized as non-use, the wearer of the sunglasses 100 or goggles 200 is switched to the driving mode or energy-saving sleep mode A function selection button (not shown) is provided to arbitrarily select.

By the structure as described above, the user selects the function selection button of the sunglasses 100 or the goggles 200 ON / OFF to switch to the driving mode or the sleep mode arbitrarily (S59).

In other words, you are driving a vehicle in a certain place such as a beach, road, road, etc., where the intensity of illumination is consistently higher than the standard value, or in a high-light environment such as outdoor direct sunlight, or in a specific place and a specific environment. Even if the illuminance above the reference value is continuously generated without any change, even if the illuminance is maintained without change for a certain time, the wearer of the sunglasses 100 or the goggles 200 operates the OFF button of the function selection button. Therefore, the LCD panel 1211 of the sunglasses 100 or the goggles 200 is prevented from being switched to the power saving sleep mode and simultaneously proceeds to the driving mode.

Here, the function selection button for the wearer to arbitrarily select the driving mode or the energy-saving sleep mode is provided on the main body 111 or the first and second leg portions 112a and 112b of the sunglasses 100 or the goggles 200. It is preferable that the frame 210 or the band 250 is provided, but is not limited thereto.

On the other hand, when the user is using the sunglasses 100 or goggles 200, but does not require the role of the sunglasses 100 or goggles 200, the wearer operates the ON button of the function selection button sunglasses ( 100 or the LCD panel 1211 of the goggles 200 is prevented from being switched to the operation mode and at the same time proceeds to the power saving sleep mode.

According to the structure as described above, the wearer arbitrarily turns ON the function selection button to switch to the power saving sleep mode, or minimizes the power consumption by operating the function selection button OFF, and proceeds through the steps of wearing and detecting the illumination and detecting the illumination change. The mode is entered.

Accordingly, when the wearer of the sunglasses 100 or the goggles 200 does not need to switch from the driving mode to the power saving sleep mode in consideration of the surrounding environment and the situation, the wearer 100 or the goggles 200 may provide an optimal environment to the wearer by arbitrarily selecting. .

Meanwhile, in the above embodiment, the power saving sleep mode according to the present invention has been described with reference to the embodiment in which the sunglasses 100 are applied. As shown in FIG. 5, the frame 210, the lens 221, and the solar cell 240 are illustrated. The same is also applicable to the goggles 200 having the band 250 and).
