DETAILED DESCRIPTION
[0025] The utility model discloses the specific embodiment of the utility model is as follows, and the technical scheme of the utility model is further described in connection with the drawings, but the utility model is not limited to these embodiments.
[0026] As Figure 1 — Figure 3 The utility model discloses an improved light guide plate, which comprises a bottom plate 100, a vertical plate 200, a light guide column 110, a first lens 120, a second lens 210 and a third lens 220.
[0027] One end of the vertical plate 200 is arranged on the bottom plate 100, and the vertical plate 200 is perpendicular to the bottom plate 100. The bottom of the bottom plate 100 is provided with at least two light guide columns 110. The bottom plate 100 is provided with the same number of first lenses 120 as the number of light guide columns 110. One end of the vertical plate 200 close to the bottom plate 100 is provided with the same number of second lenses 210 as the number of first lenses 120. The side of the other end of the vertical plate 200 away from the bottom plate 100 is provided with the same number of third lenses 220 as the number of second lenses 210. When installing, people need to install the light guide plate on a solenoid valve (not labeled in the figure) suitable for the light guide plate. Then, the light guide column 110 is inserted into the solenoid valve, and the lamp (not labeled in the figure) in the solenoid valve is located directly below the light guide column 110. When the light guide column 110 obtains a light source, the light source will be transmitted through the first lens 120, the second lens 210 and the third lens 220 in turn. Specifically, when one of the lamps emits light, the light will be transmitted into the light guide column 110. Because the first lens 120 is located directly above the light guide column 110, and the first lens 120 is inclined relative to the bottom plate 100, the second lens 210 is inclined relative to the vertical plate 200, and the reflective surface of the first lens 120 is opposite to the reflective surface of the second lens 210. In this way, the first lens 120 will reflect the light onto the second lens 210. The third lens 220 is inclined relative to the vertical plate 200. The second lens 210 and the third lens 220 are connected to two opposite surfaces of the vertical plate 200 respectively, and the reflective surface of the second lens 210 is opposite to the reflective surface of the third lens 220. In this way, the light reflected by the second lens 210 will be transmitted to the third lens 220. In the utility model, the cross-sectional shape of the third lens 220 is wavy. In this way, the light transmitted to the third lens 220 will be reflected uniformly to the outside of the vertical plate 200. Then, people can directly judge whether the lamp in the solenoid valve emits light by observing whether the vertical plate 200 emits light.
[0028] The first lens 120 is located inside the base plate 100, the third lens 220 is located inside the vertical plate 200, and the second lens 210 is located at the bottom of the vertical plate 200 with its reflective surface facing inward. Therefore, when the light source is transmitted through the first lens 120, the second lens 210, and the third lens 220 in sequence, the light source will only be transmitted inside the base plate 100 and the vertical plate 200. Only after being reflected by the third lens 220 will the light source be reflected outward from the vertical plate 200.
[0029] The vertical plate 200 is recessed inward on the side facing the base plate 100 to form a wall groove 230. The wall groove 230 separates two adjacent third lenses 220 and two adjacent second lenses 210. Specifically, the wall groove 230 divides the vertical plate 200 into a left plate 250 and a right plate 260. The left plate 250 and the right plate 260 are each provided with a third lens 220 and a second lens 210. In this way, the light sources on both sides of the wall groove 230 can be separated to prevent the light sources on the left and right sides of the wall groove 230 from running around randomly, so that when people look at the light guide plate, they can clearly see which lamp is emitting light.
[0030] A perforation 130 is provided at one end of the base plate 100 near the vertical plate 200. Branch plates 140 are provided on both sides of the perforation 130 on the base plate 100. The first lens 120 faces the corresponding branch plate 140. One branch plate 140 is connected to the bottom of the left plate 250, and the other branch plate 140 is connected to the bottom of the right plate 260. When the first lens 120 reflects the light source, the first lens 120 will reflect the light source into the corresponding branch plate 140. Since the branch plate 140 is connected to the left plate 250 or the right plate 260, the light source in the branch plate 140 will be transmitted to the left plate 250 or the right plate 260, and reflected onto the third lens 220 through the corresponding second lens 210.
[0031] The vertical plate 200 is provided with a mounting hole 240 at the wall groove 230. Through the setting of the mounting hole 240, the vertical plate 200 can be connected to the solenoid valve with bolts or self-tapping screws so that the light guide column 110 can be stably inserted into the solenoid valve.
[0032] The following is the working principle of an improved light guide plate according to this utility model:
[0033] 1. The light guide column 110 receives the light source from the lamp inside the solenoid valve;
[0034] 2. The light source is reflected by the first lens 120 to the corresponding branch plate 140, and then the branch plate guides the light source to the second lens 210 in the left plate 250 or the right plate 260.
[0035] 3、The second lens 210 reflects the light source to the third lens 220 again.
[0036] 4、The third lens 220 finally reflects the light evenly out of the vertical plate 200, so that the user can intuitively see which area emits light, thereby judging which lamp emits the light.
[0037] According to the working principle of the above light guide plate, in addition to using the light guide plate for the electromagnetic valve, the light guide plate can also be applied to the following scenarios:
[0038] 1、In the factory automation environment, this light guide plate can be used for machine status indicator lights, such as fault alarms, operation modes (running / stop), maintenance reminders, etc., its high visibility and precise light source positioning allow workers to quickly identify information from a distance;
[0039] 2、The light guide plate can be applied to emergency exit signs, fire alarms or other public area safety prompt devices. The wavy design of the third lens 220 ensures uniform light distribution, providing clear and visible guidance even in dim environments;
[0040] 3、Smart home products such as smart refrigerators, washing machines, ovens, etc. can use this light guide plate to display working status or setting options. The user interface will be more intuitive and friendly, reducing the possibility of misoperation;
[0041] 4、Vehicle instrument panels and control panels can integrate light guide plate technology to indicate key driving information such as fuel level, speed, temperature, and warning signals, which not only improves the speed of information acquisition for drivers, but also enhances the design aesthetics of the vehicle interior;
[0042] 5、Medical devices such as electrocardiographs, infusion pumps, ventilators, etc. require accurate and easy-to-understand status indicators. By using this light guide plate, medical personnel can more easily monitor changes in patients' vital signs or treatment progress;
[0043] 6、Subway and bus route maps and arrival information displays can use light guide plates to achieve more efficient information transmission. Passengers can clearly see the approaching station or transfer information, especially in crowded and noisy environments;
[0044] 7、Commercial billboards or museum exhibit placards can use light guide plates to attract the attention of viewers and present text or patterns in an aesthetically pleasing manner. The wavy reflective surface helps create a unique visual effect while ensuring information readability;
[0045] 8、Handheld devices such as smartphones and tablets can use small-sized light guide plate components for charging indicator lights or status notifications, providing instant feedback to users without occupying too much space.
[0046] In summary, the improved light guide plate is suitable for many fields due to its efficient light propagation characteristics and design flexibility, which can improve the human-computer interaction experience and increase the product aesthetics and technical content.
