Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a visual stress relieving light emitting diode (LED)

The present invention relates to a visual stress relieving LED lighting device, and more particularly, to a visual stress relieving LED lighting device capable of relieving a user's visual stress.

The term visual stress depends on the person's perspective. From an ophthalmologic point of view, it appears as a result of incomplete function of the visual system and it is possible to correct it sufficiently. However, visual stress also occurs in people with normal visual function, and is closely related to photophobia and photosensitivity syndrome. Symptoms and signs of visual stress can be found in response to certain visual images, geometric patterns of lines.

Visual stress occurs when the brain is overloaded with a specific image and neurons in the cerebral cortex are stimulated too strongly to stimulate other cells inappropriately. Characters can also be viewed as geometric patterns of lines, which can lead to visual stress when reading text in books, computers, cell phones, and, in severe cases, migraine headaches or reading difficulties.

Visual stress causes migraine, dizziness, decreased reading ability, and is known to occur in 5 ~ 20% of the total population depending on severity of symptoms.

Screening for visual stress can be used as a screening test for visual dyslexia, but it can not be judged that there is visual stress or visual dyslexia. Visual dyslexia has symptoms called photosensitivity syndrome.

The visual dyslexia screening test is widely known as the Wilkins Reading Rate Test in the UK and the screening test of the irlen in the United States. The common features of the two tests are: first, using color; second, using the speed and error of reading text; and third, asking about symptoms related to visual defects and referencing the response to the screening process. However, children who have been asked questions during the questioning process may be misleading and may receive unreliable answers. Children also tend to think the symptoms are normal. In the United States, irlen said that if there are three or more symptoms of the questionnaire, the person is suspected to have a type of visual stress, photsensitive syndrome.

Although general LED illumination can emit light of various colors, it is impossible to reduce visual stress.

Korean Patent No. 10-0990000 discloses a method and apparatus for providing a color overlay that alleviates visual stress.

1 and 2, a visual stress relieving LED lighting apparatus 1000 according to an exemplary embodiment of the present invention includes an LED light emitting unit 100, a controller 200, a storage unit 250, and a communication unit 300 The control unit 200 controls the illumination color of the LED light emitting unit 100 based on the illumination color information transmitted from the communication unit 300 or the illumination color information stored in the storage unit.

The LED light-emitting unit 100 emits light of RGB colors.

The LED light emitting unit 100 uses an LED. Light emitting diodes (LEDs) are classified as monolithic LED displays and hybrid LED displays. Due to the characteristics of semiconductors, it has great advantages in terms of processing speed, power consumption, and life span. It is popular as an electronic display part of various electronic products, and it does not cause snowing or short-circuit of elements like conventional bulb lamp. It is manufactured in a small size and widely used as various display devices, and its lifetime is high due to its semi-permanent lifetime (about 1 million hours).

It is a semiconductor device that emits light. It is used in electronic display boards such as various electronic products and automobile instrument panel. LED light color can realize RGB color. Depending on the content of impurities added, the wavelength varies depending on the content of the material. The wavelength ranges from 400 nm to 700 nm, which is the visible region of human light. The red wavelength is about 700 nm, the green wavelength is about 655 nm, 85 nanometers, and the orange color has a wavelength of 635 nanometers.

The control unit 200 is connected to the LED light emitting unit 100 and controls an illumination color of the LED light emitting unit 100.

The controller 200 controls the RGB light emitting color of the LED light emitting unit 100 to minimize the visual stress to the user.

At this time, the RGB illumination color which can minimize the visual stress to the user can be discriminated through the reading inspection and the color vision inspection, and the RGB illumination color thus discriminated is stored, and the controller 200 controls the LED And controls the light emitting unit 100 to emit light.

A visual stress test and a color vision test can be performed using a smart device, a mobile device, a tablet, a computer, etc., and the results of the visual stress test and the color vision test can be transmitted to the visual stress test apparatus according to an embodiment of the present invention. (See Fig. 1)

The visual stress test can be carried out as follows.

As shown in FIGS. 3 to 4, a certain number of overlap samples among a plurality of overlap samples in which different color filters are overlapped on a black sample text sample on a white background are displayed to a user.

The read sample is in black on the background of the sample, and the overlap sample is a sample showing the effect of applying the color filter to the read sample. That is, the overlapped sample refers to a sample that is displayed when a cardboard or the like is put on a read sample. It should be noted that this does not change the background color. This is because it is necessary for the user to discriminate the most comfortable form when applying the color-applied glasses or illumination, and to overlap not only the background but also the text.

The overlap sample is not intended to be used in a test such as a user directly reading from beginning to end or searching for a specific word, and is provided to intuitively select an overlap sample that a user can read easily among a plurality of overlap samples. This is because it takes a long time to read the overlapped sample and it is possible to reduce the reading speed of the test result due to the accumulated fatigue during the long time, It is provided to finish the inspection by selecting the overlapped sample that feels the easiest of the sample. At this time, it is preferable to use an overlap sample in which 12 or more color filters overlap.

As shown in FIGS. 3 to 4, the process of selecting the overlapped sample that is most clear and comfortable for the user is repeated to find a final overlap color.

FIG. 3 shows six samples of 12 overlap samples, among which AP636 colors are selected. FIG. 4 shows the remaining six samples, of which AQ640 colors are selected . 3 is displayed in the lower right corner A of the screen in Fig. 3, and the color selected in Fig. 4 is displayed in the lower right corner B of the screen in Fig.

Reading samples in black text on a white background may have a high degree of stress because the contrast sensitivity is 100%. Most people experience visual stress during their daily lives even if they are normal color vision. By finding an overlap sample with the least visual stress, it can be applied to the illumination applicable to everyday life or the color of a color lens.

It is further preferable that the final color thus selected is finally compared with a black sample on the white background, as shown in Fig. 5, to finally confirm whether overlaying is helpful to the user.

The color we perceive is not the intrinsic color of the object, but the color of light that the object partially absorbs and partially reflects. For example, purple appears at 430 nm, green at 520 nm, yellow at 575 nm, and red at wavelengths of 650 nm. Visible light is a part of the electromagnetic spectrum and its wavelength ranges from 350 to 750 nm. That is, the color is a phenomenon produced by a combination of light wavelengths of visible light spectrum. However, the color of a person who recognizes this color is not a physical characteristic inherent to a subject in a subjective sense, but a result created by an individual through his or her own eyes and the nervous system.

Therefore, even if the same object is seen, the perception of color may be slightly different depending on the person. However, there is no problem in communicating or exchanging information in everyday life, but there is a case where the color difference is different from that of a normal person beyond the difference of fine color recognition. The characteristic of color hue is that it can not recognize any color at all or distinguish it from other colors.

The recognition of color depends specifically on the function of the cone cell, one of the photoreceptors in the retina. Therefore, when there is an abnormality in the function of these cone cells, a color vision abnormality occurs immediately.

Hue is a common symptom, occurring in approximately 5% to 8% of the total male population. In the West, 8% of males and 0.5% of females are color vision defects. In Korea, 5.9% of all males and 0.4% of females are known to have color vision defects.

Deuteranomaly is the most common color vision disorder, accounting for 25 ~ 45% of total color vision. Followed by Deuteranopia, Protanopia, and Protanomaly. However, these three frequencies are similar, accounting for about 1% of the total male population. Third color blindness or complete color blindness is very rare and has a frequency of about 0.005%.

Screening, grading, diagnostic, and vocational tests can be classified according to the purpose of the test.

There are Pseudoisochromatic plates test, Ishihara pseudoisochromatic plates test, Hardy-Rand-Rittler pseudoisochromatic plates test, and so on. There are color test methods for the degree of accuracy test. There are FM 100 color test (Farnsworth-Munsell 100-hue test) and panel D-15 test in detail. There are anomaloscopes as a diagnostic method of diagnosis confirmation. There is a Lantern test as a test method of job aptitude test.

Since the function of the cone cell is inherent in the problem of color vision, fundamental treatment is not yet possible. However, it is possible to partially correct color anomalies with colored contact lenses or glasses, which is a partial improvement such as Ishihara's color matching test. Therefore, instead of improving the color discrimination ability itself, by enhancing the contrast of the adjacent two colors, one side is made to be brighter and the other side is made to be relatively dark, thereby enhancing the difference in contrast and brightness so that the two colors can be more easily distinguished.

Therefore, the actual color recognition ability may be rather reduced. Currently available contact lenses are approved by the Food and Drug Administration in major countries. Available in 7 ~ 8 different types of lenses, it is possible to select the most effective color lens by directly checking the color gamut, and magenta color is the most used. However, this method is not helpful for all color blindness, and it can be selectively applied only if the distinction of the color is very important for the person's work or life. Rather, It is recommended that you decide with your ophthalmologist very carefully after consultation and examination.

That is, it is possible to discriminate the degree of color blindness, color weakness and color weakness, but it is difficult to give a prescription for color weakness, so that the test for general color vision abnormality can be easily performed, To prescribe, you can check for color vision problems.

As shown in FIG. 6, the test for color vision abnormality (color vision inspection) displays one of a plurality of color samples as a reference color 10, and arranges the other color samples irregularly to display to the user.

Selecting a color sample most similar to the reference color, updating a color sample selected by a user to a reference color, and selecting a color sample most similar to the updated reference color, The results for the color samples and the color samples sequentially store the time 20 selected by the user.

And then selects the color samples that are considered closest to the reference color in order. At this time, the reference color is changed to a color sample selected by the user each time the user selects a color sample.

In other words, the color samples selected by the user disappear from the arranged positions, and the color sample selected by the user is updated to the reference color at the position where the reference color is displayed. This is to intuitively show the reference color for comparison when selecting the next color sample.

The color samples can be color-coded using the colors used for the FM 100 color test (Farnsworth-Munsell 100-hue test), panel D-15 test, or using the standard colorimetric or RGB color table made according to the industry standard , Where the color table is meant to include a color wheel (such as Munsell's 20 color wheel).

The degree of color blindness and the degree of color blindness can be determined on the basis of the result of the color selected by the user and the time when the color sample is selected by the user. That is, based on the results of the color vision test, it is possible to discriminate which color is hard to distinguish, and how difficult it is if it is difficult. This can be determined by how many times the wrong place occurred.

Although the reading test alone can find an appropriate overlap color, it is possible to improve the reliability of the reading test by discriminating the degree of color vision abnormality and the degree of color vision abnormality through the color vision test. This is because the result of the reading test can not be relied on if the color vision test is judged as a color blindness, because the ability to distinguish the color is insufficient. In other words, it is desirable to perform the color vision test in parallel to confirm the reliability of the reading test.

If the final overlay color thus determined is applied to a lens (such as a spectacle) or a lamp, the visual stress of the user can be minimized.

This is because it is possible to lower the contrast sensitivity of the user by the overlaid color, thereby improving the reading ability and lowering the stress.

The storage unit 250 is connected to the controller 200 and stores illumination color information for controlling the illumination color of the LED light emitting unit 100.

As described above, the illumination color information stored in the storage unit 250 refers to RGB illumination color information that can minimize visual stress to the user through reading inspection, color vision inspection, and the like.

The controller 200 may select one of the plurality of illumination color information stored in the storage unit 250 and output the selected illumination color information to the LED light emitting unit 250. [ 100) according to the present invention. This is to provide a personalized type of illumination capable of minimizing individual visual stress even when a plurality of people use the visual stress relieving LED illumination apparatus 1000 according to an embodiment of the present invention.

The communication unit 300 can communicate with the outside and is connected to the control unit 200 or the storage unit 250 to transmit the illumination color information received from the outside to the control unit 200, do.

That is, the communication unit 300 may receive the illumination color information from the external device to minimize the visual stress to the user, and may store the information in the control unit 200 or the storage unit 250.

The communication unit 300 may be a communication unit that uses at least one of Bluetooth, Zigbee, Ultra Wide Band (UWB), Radio Frequency Identification (RFID), and Wi- Is used as the light source.

A typical portable device preferably uses Bluetooth and Wi-Fi. This is because most devices support Bluetooth and Wi-Fi.

The communication unit 300 may include a MAC address (media access control) address, an International Mobile Station Equipment Identity (IMEI), a User Device IDentification (UDID) UUID: Universally Unique IDentifier) to the storage unit 250 together with the illumination color information, and the control unit 250 stores the unique identification information of the external device connected to the communication unit And the illumination color of the LED light-emitting unit 100 is controlled by selecting the stored illumination color information.

This is because the control unit 200 confirms the unique identification information of the external device connected to the communication unit 300 to determine which user is going to use the visual stress relieving LED illumination device 1000 according to an embodiment of the present invention can do. In other words, even if there is no separate request from the user, once the user is stored, the user can confirm the RGB lighting color that minimizes the visual stress, and by illuminating the RGB lighting color, Can be solved.

A MAC address (media access control) address is an address of a network device in the MAC layer in a network structure, and is usually stored in the ROM of the network card.

A User Device IDentification (UDID) is an identifier for identifying a user device. It is a kind of serial number.

A Universally Unique Identifier (UUID) is a 128-bit number used to identify an object or entity on the Internet. It is a nearly uniquely identifiable identifier made up of a combination of space and time (up to about 3400 years), and is used for a variety of purposes ranging from extremely short time objects to permanent object identification. There is no registration procedure for certification bodies, but only a unique identification number of the generic single identifier generation program is required. For example, if a certain product's MAC address is stored in a specific server, a problem such as leakage of personal information may occur, so that it can be used as an identifier for storing and storing a MAC address.

Various unique identification information (identifiers) have been described above, and one device can have a plurality of unique identification information.

For example, if the mobile phone is capable of Wi-Fi and Bluetooth communication, it has various unique identification information such as an identifier (UDID) of the mobile phone device itself, a MAC address for the Wi-Fi chip, and a MAC address for the Bluetooth chip.

As a result, the visual stress-relieving LED illumination device according to an embodiment of the present invention is further developed in an emotional LED capable of expressing various colors, And to provide a visual stress relieving LED illumination device.

It is to be understood that the invention is not limited to the above-described embodiment, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
