Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a high-light-transmittance anti-glare polycarbonate lampshade. Background Art

[0002] Glare is an undesirable lighting phenomenon. When the brightness of the light source is extremely high or there is a large difference in brightness between the background and the center of the field of vision, glare will occur. Glare not only reduces the visibility of objects, but also makes the user's vision uncomfortable, affecting the user's vision health.

[0003] Most existing lighting fixtures use direct light. Although the light energy utilization rate is high, the structure is simple and easy to design, the direct light source can easily affect the human eye. Although there are anti-glare lamps, there are still certain limitations. For example, the patent number CN201910550893.X discloses an anti-glare structure of "the anti-glare lampshade includes a straight cylindrical portion, the straight cylindrical portion is integrally connected to the large opening end, the ratio of the height of the tapered cylindrical portion to the height of the straight cylindrical portion is 0.5 to 2, and the height of the tapered cylindrical portion and the height of the straight cylindrical portion are greater than or equal to 3mm". That is, each light source is equipped with a straight cylindrical portion and a tapered cylindrical portion, and the light source is refracted to achieve an anti-glare effect. This anti-glare structure is relatively complex and costly, and due to multiple refractions, the brightness of the light source will be reduced and the temperature of the lampshade will increase. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a high-light-transmittance and anti-glare polycarbonate lampshade.

[0005] The utility model is achieved in this way:

[0006] A high-transmittance anti-glare polycarbonate lampshade comprises a lampshade body and an anti-glare mechanism, wherein the lampshade body comprises a fixing ring, a light-transmitting plate is installed on the inner top of the fixing ring, a protective cover is installed inside the fixing ring below the light-transmitting plate, the anti-glare mechanism comprises a connecting ring, an anti-glare plate is installed inside the connecting ring, a plurality of honeycomb holes are opened on the top of the anti-glare plate, and the connecting ring is installed on the inner bottom of the fixing ring.

[0007] The beneficial effect of adopting the above further scheme is that, when the light emitted by the lamp tube passes through the light-transmitting plate, the transmitted light will be emitted in a diffusely reflected state. This process can reduce the possibility of glare. Then, after the emitted light passes through a number of honeycomb holes, the honeycomb holes can block and disperse the light to increase the shading angle. Because the larger the shading angle, the smaller the glare value, the purpose of reducing glare can be further achieved.

[0008] Furthermore, the ratio of the diameter of the anti-glare plate to the side length of the honeycomb hole is 1:0.3.

[0009] The beneficial effect of adopting the above further solution is that, by limiting the size of the anti-glare plate and the honeycomb holes, the anti-glare plate of any size has a suitable number of honeycomb holes to ensure the anti-glare ability of the anti-glare plate.

[0010] Furthermore, a first thread is provided on the outer side of the connecting ring, a second thread is provided on the inner bottom of the fixing ring, and the first thread and the second thread are engaged with each other.

[0011] The beneficial effect of adopting the above further solution is that the connecting ring can be freely disassembled and assembled by using the first thread and the second thread. In an environment where strong light is required, the illumination brightness of the lamp tube can be increased by removing the connecting ring.

[0012] Furthermore, a third thread is provided on the inner top of the fixing ring, and the fixing ring can be engaged and connected with the lamp holder through the third thread.

[0013] The beneficial effect of adopting the above further solution is that, by utilizing the third thread, it is possible to achieve the purpose of facilitating the user to disassemble and assemble the lampshade.

[0014] Furthermore, the light-transmitting plate is made of frosted glass.

[0015] The beneficial effect of adopting the above further solution is that, because the surface of the frosted glass is uneven, light is reflected by the frosted glass and emitted in all directions, thereby preventing glare.

[0016] Furthermore, the protective cover is arc-shaped and is made of polycarbonate.

[0017] The beneficial effect of adopting the above further solution is that the arc-shaped protective cover can increase the irradiation range of light, and the light transmittance of polycarbonate is usually between 80% and 90%, so the light transmittance of the protective cover made of it is better.

[0018] Furthermore, the fixing ring is made of opaque plastic.

[0019] The beneficial effect of adopting the above further solution is that the fixing ring made of opaque plastic can prevent light from emitting through it.

[0020] Furthermore, the smoothness of the inner surface of the fixing ring is less than the smoothness of the outer surface thereof.

[0021] The beneficial effect of adopting the above further solution is that the light reflected therein can be emitted in a diffuse reflection manner.

[0022] The beneficial effect of the utility model is as follows: the utility model obtains a high-transmittance anti-glare polycarbonate lampshade through the above design, which utilizes a translucent plate. When the light emitted by the lamp tube passes through it, the transmitted light will be emitted in a diffuse reflection state. This process can reduce the possibility of glare. After the emitted light passes through a plurality of honeycomb holes, the honeycomb holes can block and disperse the light to increase the shading angle. Because the larger the shading angle, the smaller the glare value, so the purpose of reducing glare can be further achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 2 of the utility model of a high light transmittance anti-glare polycarbonate lampshade

[0034] Reference Figure 1-Figure 4 Specifically, the ratio of the diameter of the anti-glare plate 2002 to the side length of the honeycomb hole is 1:0.3. By limiting the size of the anti-glare plate 2002 and the honeycomb hole, the anti-glare plate 2002 of any size has a suitable number of honeycomb holes to ensure the anti-glare ability of the anti-glare plate 2002. The light-transmitting plate 1002 is made of frosted glass. Since the surface of the frosted glass is uneven, the light is reflected through the frosted glass and emitted in all directions, thereby preventing glare.

[0035] Embodiment 3 of the utility model of a high light transmittance anti-glare polycarbonate lampshade

[0036] Reference Figure 1-Figure 4Specifically, a first thread 2003 is provided on the outer side of the connecting ring 2001, and a second thread 1005 is provided on the inner bottom of the fixing ring 1001, and the first thread 2003 and the second thread 1005 are engaged with each other.

[0037] Specifically, the working principle of this kind of high-transmittance anti-glare polycarbonate lampshade is as follows: when in use, the lampshade is installed on the lamp holder to be adapted using the third thread 1004. When the lamp tube on the lamp holder is powered on, the light-transmitting plate 1002 is used. When the light emitted by the lamp tube passes through it, the transmitted light will be emitted in a diffusely reflected state. This process can reduce the possibility of glare. After that, the emitted light passes through a number of honeycomb holes, which can block and disperse the light to increase the shading angle. Because the larger the shading angle, the smaller the glare value, so the purpose of reducing glare can be further achieved.
