Description

Display device for filtering high energy short wavelength blue lens

The present invention relates to a display device, and more particularly to a display device for filtering high-energy short-wavelength blue lenses.

In the existing optical glasses, there are two main methods for explaining that the lens has a blue light filtering function:

1. Using a transmittance meter to detect, the detection principle is to penetrate the filter blue light beam by the light emitted by a light source (usually a halogen lamp), and then detect the light passing through the blue filter lens. Whether there is a blue wavelength of a specific band (400~500nm) and a measurement data is produced. However, for the general public, the result of obtaining only the measurement data is not intuitive enough for the optical examiner to explain. What are the advantages of the blue light filtering function of the lens, which has the advantage of reducing the "macular part" and "crystal" in the eye tissue from high-energy short-wavelength blue light and causing "macular plaque lesion" or "early cataract"? situation. In addition, the penetration rate measuring instrument is a sophisticated optical instrument, and the purchase cost is also high.

Second, the use of the past detection of sunglasses lenses is based on the UVA wavelength, such as holding a blue laser pen (commonly known as the wavelength of about 400nm, but the actual wavelength is shorter than 400nm 380nm) to illuminate a piece of white paper, the white paper A blue light spot is formed, and then the blue light-emitting lens is placed between the blue laser pen and the white paper. If the blue light spot on the white paper disappears, it means that the lens has a blue light filtering function. The advantage is that it is cheap, and it is intuitive for the public to confirm that the lens has a blue light filtering function because the blue light spot disappears. However, the general public's blue wavelength is between 400nm and 500nm, and the blue light in the 400nm~420nm band is a harmful blue light with high energy and short wavelength for the eyeball, and blue light for the 420nm~500nm band is for the eyeball. It belongs to the high-energy short-wavelength beneficial blue light. It can be understood that the method of detecting the sunglasses lens in the past does not substantially ensure that the detected blue-light lens can block wavelengths shorter than 420 nm, and can only confirm at most. The detected blue-blue lens is capable of blocking wavelengths shorter than 380 nm.

In addition, this method is inconvenient and inconvenient in use because it needs to continuously press the switch of the laser pen. Moreover, for the people whose eye structure is less clear, it is difficult to simply see the blue light spot on the white paper. It is directly associated with the location of the "macular portion" and "crystal" of the eye tissue that is vulnerable to high-energy short-wave blue light damage.

Therefore, the purpose of the present invention is to provide a display device for filtering high-energy short-wavelength blue lenses that facilitates teaching explanation.

Therefore, the display device of the novel high-energy short-wavelength blue lens comprises a platform unit, an illumination unit, and a false eye unit.

The platform unit includes a substrate having a first side portion and a second side portion disposed oppositely.

The light emitting unit is disposed on the first side of the substrate, and includes a blue light source facing the second side and having a wavelength between 400 nm and 420 nm.

The dummy eye unit is disposed on the second side of the substrate. The fake eyeball unit is configured to receive light energy emitted by the blue light source of the light emitting unit, thereby displaying a spot forming region recognizable by the human eye.

The function of the display device of the novel high-energy short-wavelength blue lens is to detect whether the lens has a blue-light filtering function, and can use the fake eyeball unit to explain to the public that the eye tissue is vulnerable to high-energy short-wave blue light damage. Where is the yellow spot and the crystal?

Since the blue light source 23, the visible light emitting diodes 241-246, the first USB transfer port 26 and the circuit board 25 are electrically connected to each other, it is well known to those skilled in the art. It is not the focus of this new model, so it will not be repeated. The blue light source 23 emits blue light having a wavelength of 400 nm to 420 nm, and the present invention adopts a blue laser light source having a wavelength of 405 nm, and the circuit board 25 has stable power and voltage functions to ensure blue laser light. The light source is stable to avoid errors caused by test environment problems.

Referring to Figures 2, 3 and 6, the hollow base 21 has a first vertical wall 211, a second vertical wall 212 spaced apart from the first vertical wall 211 along the first horizontal axis X, and a The first vertical wall 211 and the top wall 213 of the second vertical wall 212 are connected above the substrate 11 .

The circuit board 25 is located within the hollow base 21. The cover plate 22 is disposed on the top wall 213 of the hollow base 21, and includes a top surface 221 and a first pattern on the top surface 221 corresponding to the visible light emitting diodes 241-246. The portions 222 to 227 and a second pattern portion 228 located on the top surface 221 and corresponding to the blue light source 23 .

Referring to FIGS. 1, 2, and 4, the power unit 3 is electrically connected to the circuit board 25, and is configured to provide the required power of the blue light source 23 and the visible light emitting diodes 241-246. The power unit 3 includes a mobile power source 31 and a transmission line 32. The mobile power source 31 has a second USB port 311. The two ends of the transmission line 32 are detachably electrically connected to the second USB port 311 of the mobile power source 31 and the first USB port 26 of the light unit 2. The switch unit 4 is electrically connected to the circuit board 25 and the power unit 3.

Referring to FIGS. 1, 3, and 6, the dummy eye unit 5 is disposed on the second side portion 112 of the substrate 11. The false eyeball unit 5 is configured to receive the light energy emitted by the blue light source 23 of the light emitting unit 2, thereby displaying a light spot forming region 512 recognizable by the human eye. Specifically, the fake eye unit 5 includes a half-eye ball 51 with an opening facing upward, and a lesion sticker 52. The half-eye ball holder 51 has a light passage region 511 with respect to the blue light source 23, and the light spot formation region 512 disposed opposite to the light passage region 511. The light passing region 511 is interposed between the blue light source 23 and the spot forming region 512, and the lesion sticker 52 is detachably attached to the spot forming region 512 of the half eye socket 51.

It is worth mentioning that the pseudo eye unit 5 itself can be a fluorescent powder containing an absorbable wavelength of 400 nm to 420 nm and capable of exciting fluorescence. Specifically, the pseudo eye unit 5 itself is an eyeball. a fluorescent sticker, such that when the false eye unit 5 is configured to receive the light energy emitted by the blue light source 23 of the light emitting unit 2, the fluorescent powder contained in the false eye unit 5 itself absorbs light energy. The excited state is entered, and the excitation is immediately deactivated and visible light is emitted, thereby making the pseudo eye unit 5 thereby become the spot forming region 512 recognizable by the human eye.

The following describes the advantages of the novel by examining whether the lens has a blue light filtering function:

Referring to FIG. 6, in the embodiment, the wavelength range of the blue light source 23 is between 400 nm and 420 nm, and in the present embodiment, the wavelength is 405 nm. After the switch unit 4 is turned on, the laser beam emitted by the blue light source 23 (shown by a dashed arrow) is projected through the light passing region 511 of the half-eye socket 51 to the spot forming region 512. At this time, the optical examiner can attach the lesion sticker 52 to the spot formation region 512 of the half-eye ball holder 51, thereby indicating that the eye tissue "macular portion" suffering from short-wavelength blue light damage has occurred.

Referring to FIG. 3, the optical examiner can then place a blue light filter lens 91 having a blue light filtering function and a normal light lens 92 having no blue light filtering function on the groove 113 of the platform unit 1, when the optical examiner follows the first The horizontal axis Y moves to move the blue light lens 91. When the laser beam emitted by the blue light source 23 is blocked by the blue light lens 91, the light spot forming area 512 cannot be reached, thereby enabling the public to intuitively Because the blue light spot disappears, it is confirmed that the lens has a blue light filtering function. Conversely, when the blue light blue lens 91 is not disposed between the blue light source 23 and the fake eye unit 5, the normal lens 92 is changed instead. When the second horizontal axis Y is movably disposed between the blue light source 23 and the false eyeball unit 5, the laser beam emitted by the blue light source 23 can still reach the spot forming region 512. This allows the public to visually confirm that the ordinary lens 92 cannot effectively filter out blue light.

Referring to FIGS. 2, 4, and 5, the light blocking plate 12 is disposed on the substrate 11, and the imaging surface 123 of the inclined wall 122 of the light blocking plate 12 faces the light emitting unit 2, and the inclined wall of the light blocking plate 12 The position of the top edge of the 122 in the height axis Z is higher than the position of the laser beam emitted by the blue light source 23. In this embodiment, the colors appearing in the first pattern portions 222 to 227 respectively correspond to the colors emitted by the visible light emitting diodes 241-246. For example, the visible light emitting diodes The bodies 241 to 246 are respectively a red light emitting diode, an orange light emitting diode, a yellow light emitting diode, a green light emitting diode, a green light emitting diode and a purple light emitting diode, and the first patterns The portions 222 to 227 are respectively red, orange, yellow, green, enamel, and purple; the color of the second pattern portion 228 is blue, corresponding to the blue light emitted by the blue light source 23. Thus, the imaging surface 123 of the light blocking plate 12 is arranged with red, orange, yellow, green, blue, 靛, and purple spots in the second horizontal axis Y.

The blue light-emitting lens 91 is disposed between the inclined wall 122 of the light-blocking plate 12 and the light-emitting unit 2, and moves along the second horizontal axis Y. Since the blue-light lens 91 has a function of filtering blue light wavelength, Therefore, when the blue light-emitting lens 91 is sequentially moved to the visible light-emitting diodes 241-2244, the light emitted by the visible light-emitting diodes 241-244 can penetrate the blue light-emitting lens 91 and reach the The imaging surface 123 of the light blocking plate 12, so that the imaging surface 123 of the light blocking plate 12 allows the public to see red, orange, yellow, and green light spots; and when the blue light filtering lens 91 moves to the blue light source 23, respectively When the blue light emitting diode 245 and the purple light emitting diode 246 are in front, the blue, green and purple light spots originally located on the imaging surface 123 of the light blocking plate 12 will disappear, thereby being intuitively understood by the public. The lens has the function of filtering blue light shorter than 405 nm.

Referring to Figures 7 and 8, a second embodiment of a display device for filtering a high-energy short-wavelength blue lens is similar to the first embodiment, the second embodiment and the first embodiment. The main differences in the examples are:

The power unit 3 includes a plug 33 having a second USB port 331 and a second USB port 331 electrically connected to the plug 33 and a transmission line 32 of the first USB port 26 of the unit 2.

The light barrier 12 has a base wall 121 extending along the second horizontal axis Y, and an inclined wall 122 extending upward from the base wall 121 toward the light emitting unit 2. The inclined wall 122 has an imaging surface 123 facing away from the light emitting unit 2.

Compared with the light blocking plate 12 (shown in FIG. 5 ) disclosed in the first embodiment, the position of the top edge of the inclined wall 122 of the light blocking plate 12 in the height axial direction Z in this embodiment is Below the position of the laser beam emitted by the blue light source 23. At the time of detection, the imaging surface 123 of the inclined wall 122 of the light blocking plate 12 faces away from the light emitting unit 2, and then the blue filtering lens 91 is disposed adjacent to the inclined wall 122 of the light blocking plate 12, at this time, In addition to being able to confirm that the blue light lens 91 does have a blue light filtering function because the blue light spot formed in the light spot forming region 512 disappears, the image surface 123 of the light blocking plate 12 does not have a blue light spot or a weak brightness. The blue light spot can further confirm that the blue light-emitting lens 91 is a coating technology that absorbs the blue light wavelength. Conversely, if the image surface 123 of the light-blocking plate 12 has a clearly visible blue light spot, the blue light-emitting lens can be confirmed. 91 is a coating technology that uses a blue light wavelength.

Thus, the second embodiment can achieve the same efficacy and purpose as the first embodiment.

Through the above description, the advantages of this embodiment can be summarized as follows:

1. The present invention can intuitively utilize the fake eyeball unit 5 to explain to the public where the eye tissue "macular portion" and "crystal crystal" which are vulnerable to short-wavelength blue light are located, and let the public clearly understand the blue light-emitting lens. When moving between the blue light source 23 and the false eye unit 5, the blue spot located in the spot forming area 512 disappears and the lens is confirmed to have a blue light filtering function.

Second, the novel can also let the public know that the blue light-emitting lens 91 does not filter visible light (such as red, orange, yellow, green, etc.) which is longer than the blue wavelength.

3. The novel can further detect that the blue light-emitting lens 91 is a coating technology that reflects a blue wavelength or a coating technology that absorbs a blue wavelength.

In summary, the novel high-energy short-wavelength blue lens display device can achieve the purpose of the present invention.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
