Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to an anti-glare light strip and its manufacturing process. Background Technology

[0002] A light strip is a lighting fixture composed of multiple LED beads. It uses a strip-shaped circuit board as a base, with the LED beads and other components arranged on the board to achieve a high-brightness lighting effect. If the circuit board is flexible, the light strip is called a flexible light strip, which has the advantages of being bendable and easy to install. If the circuit board is non-flexible, the light strip is called a non-flexible light strip, which has the advantages of high strength and structural stability.

[0003] Currently, both flexible and non-flexible LED strips can be used as in-ground lights on scenic roads to enhance the visual appeal. However, when tourists walk on roads paved with LED strips, the high brightness can cause glare and a negative experience. One solution is to design anti-glare structures on the LED strips. For example, Chinese Patent CN217540452U discloses a COB LED strip with anti-glare functionality, comprising a substrate, an LED chip, and an encapsulating colloid. The inner wall of the encapsulating colloid has a frosted layer, and the outer surface has raised patterns. Through the frosted layer and raised patterns, the light emitted by the LED chip forms soft, diffused light, creating a gentle and natural diffused light effect, thus achieving an anti-glare effect.

[0004] While the above solutions can solve the problem of glare for tourists walking on roads with LED strips in scenic areas, the LED strips will suffer from reduced brightness and insufficient light uniformity after glare reduction treatment. This reduces the visual effect of the LED strips as in-ground lights in scenic areas. Therefore, how to reduce the impact on visual effect while ensuring the LED strips have anti-glare effects is an urgent problem to be solved. Summary of the Invention

[0005] In order to reduce the impact on visual effect while achieving anti-glare effect, this application provides an anti-glare light strip and its manufacturing process.

[0006] In a first aspect, the present invention provides an anti-glare light strip, which adopts the following technical solution:

[0007] An anti-glare light strip includes a circuit board, LED chips, and a lampshade. Multiple LED chips are fixedly arranged on the top surface of the circuit board. The lampshade is concave and fixedly mounted on the top surface of the circuit board with the concave side facing downwards, covering the LED chips. A vertically retractable patterned mesh is provided on the top of the lampshade. When the patterned mesh extends upwards, it forms a raised pattern on the top of the lampshade. When the patterned mesh retracts downwards, it fits into the lampshade, making the top surface of the lampshade flat. A drive unit is externally connected to the patterned mesh to drive its vertical extension and retraction. The drive unit is connected to a controller, and a sensor is connected to the controller.

[0008] Preferably, the circuit board is a non-flexible circuit board.

[0009] Preferably, the patterned mesh includes two parallel straight rods and a pattern formed between the two straight rods, and the top of the lampshade has a groove corresponding to the shape of the patterned mesh.

[0010] Preferably, the pattern of the patterned mesh is a diamond pattern.

[0011] Preferably, both the lampshade and the patterned mesh are made of acrylic resin.

[0012] Preferably, the inner wall of the lampshade is provided with a frosted layer.

[0013] Preferably, the two opposite side walls of the recess at the bottom of the lampshade are provided with sliding grooves, and the frosted layer slides into and is installed on the inner wall of the lampshade through the two sliding grooves.

[0014] Preferably, a pressing structure is provided between the patterned mesh and the frosted layer. When the patterned mesh retracts downward, the pressing structure presses against the top surface of the frosted layer. When the patterned mesh extends upward, the pressing structure leaves the top surface of the frosted layer.

[0015] Preferably, the crimping structure includes a crimping rod and a socket. The crimping rod is disposed at the bottom of the straight rod of the patterned mesh, and the socket is formed on the groove of the lampshade and extends into the sliding groove. The socket is for the crimping rod to be inserted.

[0016] Secondly, the present invention provides a manufacturing process for an anti-glare light strip, which is applied to the aforementioned anti-glare light strip and adopts the following technical solution:

[0017] A manufacturing process for an anti-glare LED strip includes the following steps:

[0018] S1: Molds for manufacturing the lampshade and the patterned mesh respectively;

[0019] S2: The lampshade and the patterned mesh are injection molded using two sets of molds respectively;

[0020] S3: Attach the lampshade to the circuit board on which the LED chips have been arranged, and embed the patterned mesh into the top of the lampshade;

[0021] S4: Connect the patterned mesh to the drive unit, the controller, and the sensor in sequence.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. When tourists are on the road with the light strip, the top of the lampshade will automatically form a raised pattern to make the light strip have an anti-glare effect, improving the experience of tourists passing through the road with the light strip. When no tourists are on the road with the light strip, the top of the lampshade will automatically eliminate the raised pattern, thereby improving the brightness and uniformity of the light strip, thus bringing a better visual effect to tourists outside the road. This avoids the continuous reduction of the visual effect brought by the light strip due to the light strip always being in an anti-glare effect, achieving the effect of reducing the impact on the visual effect while the light strip has an anti-glare effect.

[0024] 2. When the patterned mesh retracts downwards, the frosted layer can still provide basic anti-glare effect for the light strip. When the patterned mesh extends upwards, the frosted layer, together with the raised pattern, provides better anti-glare effect for the light strip.

[0025] 3. Through the setting of the pressing structure, since the road is mostly unoccupied, the light strip is mostly in the retracted state of the patterned mesh. After the patterned mesh retracts, it can press down the frosted layer, thus ensuring that the frosted layer is in a stable installation state in most cases. If the frosted layer needs to be removed, simply control the patterned mesh to extend upwards. Furthermore, when there is a power outage, the patterned mesh will automatically retract downwards due to its own weight, ensuring that the frosted layer can still achieve stable installation in the power outage state or in the state of long-term non-use.

[0032] The following will be combined with the appendix Figure 1-5 The present invention will be further illustrated by the embodiments.

[0033] This embodiment discloses an anti-glare light strip.

[0034] Reference Figure 1 The anti-glare light strip includes a circuit board 1, LED chips 2, and a lampshade 3. Multiple LED chips 2 are arranged on the top surface of the circuit board 1. The lampshade 3 is also fixedly mounted on the top surface of the circuit board 1 and covers the LED chips 2, allowing the light emitted by the LED chips 2 to be projected outwards through the lampshade 3. This light strip is used as an in-ground light and laid on roads in scenic areas. Its application scenarios include... Figure 5 As shown, an installation groove 71 is provided on the ground of the road. The light strip is installed at the bottom of the installation groove 71. A light-transmitting floor 72 is provided on the top of the installation groove 71, which ensures that the light from the light strip can shine out of the ground and maintains the flatness of the ground. This application scenario is a conventional scenario for installing in-ground lights in the prior art.

[0035] Reference Figures 1 to 4The circuit board 1 is a non-flexible circuit board. In this embodiment, the circuit board 1 is preferably a metal substrate, such as an aluminum substrate or a copper substrate, which gives the light strip of the present invention high strength and structural stability. Furthermore, the lampshade 3 is concave and is disposed on the top surface of the circuit board 1 with the concave side facing downwards. A vertically retractable patterned mesh 4 is provided on the top of the lampshade 3. After the patterned mesh 4 retracts downwards, it fits into the lampshade 3, making the top surface of the lampshade 3 flat. In addition, a drive unit is externally connected to the patterned mesh 4 to drive its vertical retraction. The drive unit is connected to a controller, and the controller is connected to a sensor. The sensor is used to detect whether tourists have entered the road where the light strip of the present invention is laid. The sensor controls the drive component as follows: When the sensor detects that someone is on the road with the light strip, the sensor transmits the sensing signal to the controller. After receiving the sensing signal, the controller controls the drive component to move, causing the drive component to lift the patterned mesh 4 on the top of the lampshade 3, thus forming a raised pattern on the top of the lampshade 3. When the sensor detects that no one is on the road with the light strip, the sensor transmits the sensing signal to the controller. After receiving the sensing signal, the controller controls the drive component to move again, causing the drive component to retract the patterned mesh 4 on the top of the lampshade 3, thus achieving a fitted top and having a flat top surface. With the above settings, when tourists are on the road with the light strip, the top of the lampshade 3 will automatically form a raised pattern to give the light strip an anti-glare effect, improving the experience of tourists walking on the road with the light strip. When no tourists are on the road with the light strip, the top of the lampshade 3 will automatically eliminate the raised pattern, thereby improving the brightness and uniformity of the light strip, thus bringing a better visual effect to tourists outside the road. This avoids the continuous reduction of the visual effect brought by the light strip due to the light strip always being in an anti-glare effect, achieving the effect of reducing the impact on the visual effect while the light strip has an anti-glare effect.

[0036] Reference Figure 4The patterned mesh 4 includes two parallel straight rods 41 and a pattern formed between the two straight rods 41. In this embodiment, the pattern is a diamond pattern. The geometry and layout of the diamond pattern can effectively scatter light and reduce the intensity of light directly hitting the human eye, thus providing an excellent anti-glare effect. Furthermore, to allow the patterned mesh 4 to retract downwards and embed, a groove is provided on the top of the lampshade 3 corresponding to the shape of the patterned mesh 4. It should be noted that in this embodiment, the groove on the top of the lampshade 3 must ensure that the outer side of the straight rods 41 of the patterned mesh 4 is exposed outside the top of the lampshade 3, so that a drive component can be externally connected to the patterned mesh 4 to drive its extension and retraction. In addition, both the lampshade 3 and the patterned mesh 4 are made of acrylic resin. Acrylic resin is a polymer of polymethyl methacrylate (MMA) or polyethyl methacrylate (EMA), a plastic material with good permeability, weather resistance, and corrosion resistance. It also has good processability after injection molding, facilitating further processing of the mating positions between the lampshade 3 and the patterned mesh 4.

[0037] Reference Figure 4 and Figure 5 In this application scenario of the light strip, the sensor is located outside the mounting slot 71 on the ground to achieve its sensing function. In this embodiment, the sensor is a thermal imaging camera, which can convert infrared radiation into images to sense road conditions in real time. To better distinguish between humans and animals entering the road, machine learning can be used for training based on the differences in body temperature and thermal images between humans and animals. The trained model can recognize the thermal image features of humans and animals, thereby classifying them. When a human is detected on the road, the patterned mesh 4 of the lampshade 3 is raised to provide an anti-glare effect. In other embodiments, the sensor can also be a microwave sensor, an infrared sensor, an ultrasonic sensor, etc., as long as it can detect whether there are tourists on the road covered with the light strip.

[0038] Reference Figure 4 and Figure 5 In this application scenario of the light strip, the driving component is fixedly installed in the mounting groove 71 on the ground to achieve its driving function for the light strip. In this embodiment, the driving component is a miniature electric cylinder, which is fixedly installed outside the light strip. The miniature electric cylinder is fixedly connected to the patterned mesh on the top of the lampshade 3 through its telescopic rod, and the telescopic direction of the telescopic rod of the miniature electric cylinder is the same as the telescopic direction of the patterned mesh 4, so as to realize the function of the miniature electric cylinder driving the patterned mesh 4 to extend and retract. In other embodiments, cylinders, motors, or other driving components can also be used to drive the extension and retraction of the patterned mesh 4, as long as the effect of driving the up and down extension and retraction of the patterned mesh 4 can be achieved.

[0039] Reference Figures 1 to 4The inner wall of the lampshade 3 is provided with a frosted layer 5. When the patterned mesh 4 retracts downwards, the frosted layer 5 can still provide a basic anti-glare effect for the light strip. When the patterned mesh 4 extends upwards, the frosted layer 5, together with the raised pattern, provides a better anti-glare effect for the light strip. Furthermore, the opposite side walls of the recess at the bottom of the lampshade 3 are provided with sliding grooves 51. The frosted layer 5 slides into and is installed on the inner wall of the lampshade 3 through the two sliding grooves 51, so that the frosted layer 5 can be pulled out for regular replacement or removal and placement according to lighting needs. In addition, a pressing structure is provided between the patterned mesh 4 and the frosted layer 5. The pressing structure includes a pressing rod 61 and an insertion hole 62. The pressing rod 61 is located at the bottom of the straight rod 41 of the patterned mesh 4. The insertion hole 62 is opened in the groove of the lampshade 3 for the straight rod 41 to be inserted. The insertion hole 62 extends into the sliding groove 51. The insertion hole 62 allows the pressing rod 61 to be inserted. When the patterned mesh 4 retracts downward, the pressing rod 61 presses against the top surface of the frosted layer 5 to achieve stable installation. When the patterned mesh 4 extends upward, the pressing rod 61 leaves the top surface of the frosted layer 5, at which point the frosted layer 5 can be pulled out. In addition to guiding the extension and retraction of the patterned mesh 4, the pressure rod 61 and the socket 62 also have another effect: since the road is mostly unoccupied, the light strip is mostly in the retracted state of the patterned mesh 4. After the patterned mesh 4 retracts, it can press down on the frosted layer 5, thereby ensuring that the frosted layer 5 is in a stable installation state in most cases. If it is necessary to remove the frosted layer 5, simply control the patterned mesh 4 to extend upwards. Furthermore, when there is a power outage, the patterned mesh 4 will automatically retract downwards due to its own weight, ensuring that the frosted layer 5 can still achieve stable installation in the power outage state or in the state of long-term non-use.
