Description

Technical Field

[0001] This utility model relates to the field of light source detection, and in particular to an anti-glare mechanism for backlight adjustment. Background Technology

[0002] Commonly used backlights have strong illumination and a large divergence angle. Generally, the light source needs to be adjusted before use. However, when adjusting the light source, the light emitted by the light source will shine into our eyes, which can cause eye strain. This can make the adjustment difficult, resulting in inaccurate light source settings and affecting the subsequent testing results. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide an anti-glare mechanism for backlight adjustment. By controlling the angle of light through a grating film, the light will only return along the original direction and will not be reflected out from other angles, thereby ensuring that the light angle does not spread too much and glare the eyes of the adjustment personnel.

[0004] To achieve the above objectives, this utility model provides an anti-glare mechanism for backlight adjustment, including a locking component, a backlight assembly, and an anti-glare component. The anti-glare component includes an anti-stab bracket, a grating film, and a transparent plate. A hollow light-transmitting area is formed on the anti-stab bracket. The transparent plate and the grating film are stacked sequentially from top to bottom on the upper surface of the anti-stab bracket. The other end of the anti-stab bracket relative to the grating film wraps around the backlight assembly. The locking component passes through the four sides of the anti-stab bracket and locks with the backlight assembly.

[0005] Furthermore, the upper surface of the anti-stab bracket is provided with multiple first mounting holes, and the transparent plate and the grating film are respectively provided with second mounting holes and third mounting holes that match the first mounting holes. The mounting holes allow for quicker and more convenient installation of the transparent plate and the grating film, and different grating films can be quickly and easily used to adjust the light projection effect and increase the anti-stab effect as needed.

[0006] Furthermore, the transparent plate and the grating film are sequentially bonded to the anti-stab bracket along their perimeter using UV adhesive. Alternatively, they can be directly bonded using optical adhesives such as UV adhesive, achieving different methods of fixation that are flexible and convenient.

[0007] Furthermore, the locking element is a wing nut, and a fourth mounting hole is provided along the four sides of the anti-stab bracket. The locking element passes through the fourth mounting hole and abuts against the four sides of the backlight assembly for locking. Using a locking element allows it to directly pass through the fourth mounting hole and abut against the backlight assembly for locking, without needing to loosen the locking element. Installation and disassembly are very convenient and quick, the structure is simple, and production costs can be saved.

[0008] Furthermore, fifth mounting holes for locking the locking member are provided along the four sides of the backlight assembly. By providing the fifth mounting holes, the locking function of the locking member can be better coordinated, improving the stability during light source adjustment.

[0009] Furthermore, the size of the anti-stab bracket is larger than the size of the backlight assembly. This not only allows the anti-stab bracket to enclose the backlight assembly, but also creates a certain space between the backlight assembly and the anti-stab bracket to facilitate heat dissipation of the backlight assembly, thus preventing excessive temperature concentration during debugging from affecting the normal operation of the backlight assembly.

[0010] Furthermore, the upper surface of the backlight assembly is provided with a light outlet, and the depth of the anti-stab bracket is greater than the depth of the light outlet. This allows the anti-stab bracket to completely enclose the backlight assembly, preventing light from the backlight assembly from escaping from the sides of the anti-stab bracket and affecting the operator's vision, thus improving the efficiency and accuracy of the debugging process.

[0011] Furthermore, the thickness of the grating film is less than or equal to 0.5 mm. A film thickness of only about 0.5 mm does not interfere with or affect the structure of traditional backlighting, ensuring the accuracy of the calibration.

[0012] Furthermore, a sawtooth grating is formed on one side of the grating film, and the sawtooth grating faces the backlight assembly. The sawtooth grating controls the angle of light, ensuring that the light only returns along its original direction and does not reflect out from other angles. This prevents the light from spreading too much and potentially irritating the eyes of the operator, similar to the privacy screen protector on a mobile phone. It does not alter the illuminance or color temperature of the light source.

[0013] Furthermore, the sawtooth grating is tilted longitudinally at 60° or laterally. This 60° longitudinal or lateral tilt effectively enhances the reflectivity of the grating film, ensuring control over the angle of light and preventing excessive light diffusion that could irritate the eyes of the operator.

[0014] Compared with existing technologies, this invention has the following advantages: This invention adds a grating film to the bottom of the transparent plate to adjust the light divergence angle. The structure consists of a traditional backlight assembly with an added grating film. The grating film controls the light angle through its internal sawtooth grating, ensuring that the light only returns along its original direction and does not reflect out at other angles. This prevents the light from spreading too much and irritating the eyes of the operator, similar to the anti-peeping film on a mobile phone. It does not alter the illuminance or color temperature of the light source, and the film thickness is only about 0.5mm, so it does not interfere with or affect the traditional backlight structure.

If the specific posture changes, the directional indicator will also change accordingly.

[0025] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0026] Please see Figures 1 to 5 The present invention provides an anti-glare mechanism for backlight adjustment, including a locking component 1, a backlight assembly 2, and an anti-glare assembly 3.

[0027] In this embodiment, the anti-sting component 3 includes an anti-sting bracket 31, a grating film 32, and a transparent plate 33. A hollow light-transmitting area 311 is formed on the anti-sting bracket 31. The transparent plate 33 and the grating film 32 are stacked sequentially from top to bottom on the upper surface of the anti-sting bracket 31. The thickness of the grating film 32 is less than or equal to 0.5 mm. The diaphragm thickness is only about 0.5mm, which does not interfere with or affect the structure of traditional backlighting, ensuring the accuracy of the adjustment. The anti-stab bracket 31 wraps the backlight assembly 2 at the other end relative to the grating diaphragm 32. That is, the transparent plate 33 and the grating diaphragm 32 are sequentially arranged above the light-transmitting area 311, and the backlight assembly 2 is arranged below the light-transmitting area 311. The grating diaphragm 32 adjusts the light emitted from the light-transmitting area 311. To increase the reflection effect of the grating diaphragm 32, a sawtooth grating 321 is formed on one side of the grating diaphragm 32. The sawtooth grating 321 faces the backlight assembly 2. Preferably, the sawtooth grating 321 is tilted at 60° longitudinally or laterally. The 60° longitudinal tilt or the lateral tilt can effectively enhance the reflection effect of the grating diaphragm 32, ensure its control over the light angle, and prevent the light from spreading too much and piercing the eyes of the adjustment personnel.

[0028] In this embodiment, the locking element 1 passes through the four sides of the anti-stab bracket 31 and locks with the backlight assembly 2. Specifically, the locking element 1 is a wing nut. A fourth mounting hole 312 is provided on the four sides of the anti-stab bracket 31. During installation, the locking element 1 is simply passed through the fourth mounting hole 312 and locked against the four sides of the backlight assembly 2. After adjustment, the locking element 1 can be released. Installation and disassembly are very convenient and quick.

[0029] Its simple structure can save on production costs.

[0030] The connection between the anti-stab bracket 31, the grating diaphragm 32, and the transparent plate 33 can be achieved in various ways, such as... Figure 1As shown, multiple first mounting holes 313 are provided on the upper surface of the anti-stab bracket 31. The transparent plate 33 and the grating film 32 are respectively provided with second mounting holes 331 and third mounting holes 322 that match the first mounting holes 313. The mounting holes allow for quicker and more convenient installation of the transparent plate 33 and the grating film 32. Different grating films 32 can be used to adjust the light emission effect and increase the anti-stab effect as needed. Furthermore, the grating film 32 and the transparent plate 33 can be connected to the anti-stab bracket 31 by adhesive bonding. For example, the four edges of the transparent plate 33 and the grating film 32 can be sequentially bonded to the anti-stab bracket 31 with UV adhesive to achieve different fixing methods, which are flexible and convenient. Of course, in addition to the two methods mentioned above, there can be other detachable connection methods for the installation of the grating film 32 and the transparent plate 33, which will not be described in detail here.

[0031] A light outlet 22 is provided on the upper surface of the backlight assembly 2. The size of the anti-stab bracket 31 is larger than the size of the backlight assembly 2, and the depth of the anti-stab bracket 31 is greater than the depth of the light outlet 22. This not only allows the anti-stab bracket 31 to cover the backlight assembly 2, but also creates a certain space between the backlight assembly 2 and the anti-stab bracket 31 to facilitate heat dissipation of the backlight assembly 2. It also prevents the light from the backlight assembly 2 from escaping from the side of the anti-stab bracket 31, thus avoiding obstructing the view of the debugging personnel and improving the efficiency and accuracy of debugging.

[0032] In some embodiments, as Figure 5 As shown, to further ensure the stability of the locking between the backlight assembly 2 and the anti-stab bracket 31, fifth mounting holes 21 for locking the locking member 1 are provided on all four sides of the backlight assembly 2. By providing the fifth mounting holes 21, the locking member 1 can be inserted into them. Since the contact area between the backlight assembly 2 and the locking member 1 is generally a metal shell, insufficient locking force may occur when the backlight assembly 2 and the locking member 1 are in contact, leading to slippage. However, with the fifth mounting holes 21, the locking member 1 is directly inserted, preventing slippage and thus improving stability during light source adjustment.

[0033] The working principle of this utility model can be briefly described as follows: This utility model adds a grating film 32 to the bottom of the transparent plate 33 to adjust the light divergence angle. The structure is the traditional backlight component 2 plus a grating film 32. The grating film 32 controls the light angle through the internal sawtooth grating 321. The light will only return along the original direction and will not be reflected out from other angles, so that the light angle will not spread too much and irritate the eyes of the debugging personnel. The principle is similar to the anti-peeping film of mobile phones. It will not change the illuminance and color temperature of the light source. Moreover, the film thickness is only about 0.5mm, which has no interference or impact on the traditional backlight structure.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
