Abstract
Description
Technical Field
[0001] This utility model relates to the field of sign light technology, and in particular to a sign light. Background Technology
[0002] Signage lights are common lighting fixtures in fire protection and indicator lighting. Currently, most signage lights on the market use light guide plates, which can convert point or line light sources into surface light sources, so that the light shines evenly on the pattern on the panel, ensuring that the text, arrows and other markings of the signs are clearly legible.
[0003] However, in the existing technology, it is difficult to guarantee the uniformity of light effect at the indicator. The light guide plate area closer to the LED is brighter, while the light guide plate area farther away from the LED has a significantly lower local brightness due to light attenuation. This results in uneven brightness of the indicator overall, which not only affects the appearance of the product, but also reduces the efficiency of conveying the indicator information. Utility Model Content
[0004] The present invention aims to overcome the problem of uneven light effect at the indicator signs in the prior art, and provides an indicator light.
[0005] To achieve the above objectives, the present invention provides a sign light, comprising a first diffuser plate, a back plate, a frame, and a light source plate. The frame is installed between the first diffuser plate and the back plate, and the three together form an accommodating space. The light source plate is installed at one end of the accommodating space. The light ...
[0006] In one embodiment, the first lower light-blocking plate is angled toward the light source plate.
[0007] In one embodiment, the angle is 0° to 14°.
[0008] In one embodiment, the sign light further includes a second lower light-blocking plate disposed between the light source plate and the back plate.
[0009] In one embodiment, the second lower light-blocking plate is angled toward the light source plate.
[0010] In one embodiment, the sign light further includes a third lower light-blocking plate, which is disposed on both sides of the second lower light-blocking plate and is fixedly mounted on the frame.
[0011] In one embodiment, the third lower light-blocking plate is angled toward the light source plate.
[0012] In one embodiment, the frame includes at least one slot and at least one fixing post. The slot is disposed at a first end within the frame, and the upper light-blocking plate is inserted into the slot. The fixing post is disposed at a second end within the frame, and the light source plate and the first lower light-blocking plate are sequentially mounted on the fixing post.
[0013] In one embodiment, the sign light further includes a mounting bracket and a wire channel, the mounting bracket being disposed on the top of the frame, and the wire channel being formed inside the frame.
[0014] In one embodiment, the sign light further includes a mounting hole and a wire groove, the mounting bracket is disposed on the frame, and the wire groove is formed at the location where the light source plate is mounted.
[0015] In summary, this utility model provides a sign light. By installing the first lower light-blocking plate on the frame and setting the first lower light-blocking plate to an inclination of 0° to 14°, it effectively blocks some of the ineffective light from the LED beads, changes the light emission angle of the LED beads, and reflects the light into the sign light cavity, thereby effectively mitigating the problem of excessive light on the side of the diffuser plate close to the LED beads. Furthermore, the upper light-blocking plate located in the slot reflects the light projected to the top downwards, compensating for the weak light on the side of the diffuser plate away from the LED beads. This utility model, through the combined blocking and reflection of light by the upper and lower light-blocking plates, makes the light distribution within the sign light cavity more uniform, ensuring uniform luminous efficacy of the indicator sign.
[0016] To make the above-mentioned features and advantages of the utility model more apparent and understandable, specific embodiments are described below, and detailed descriptions are provided in conjunction with the accompanying drawings. Attached Figure Description

[0029] Example 1
[0030] To address the problem of uneven lighting at indicator signs in existing technologies, this utility model proposes an indicator light. Combined with... Figure 1 and Figure 2 The indicator light includes a first diffuser plate 1 and a back plate 3 (see...). Figure 3 The frame 2, light source plate 8, and light-blocking assembly are provided. The front and rear ends of the frame 2 are respectively equipped with the first diffuser plate 1 and the back plate 3. The three components together form an accommodating space. The light source plate 8 (see...) Figure 3 The light-blocking assembly is installed within the receiving space. The light-blocking assembly includes at least one upper light-blocking plate 4, a first lower light-blocking plate 5, a second lower light-blocking plate 6, and at least one third lower light-blocking plate 7. The upper light-blocking plate 4 is disposed opposite to the first light-blocking plate 5, the second lower light-blocking plate 6, and the third lower light-blocking plate 7. Specifically, the upper light-blocking plate 4 is disposed at one end of the receiving space, and the first lower light-blocking plate 5, the second lower light-blocking plate 6, the third lower light-blocking plate 7, and the light source plate 8 (see...) Figure 3All three lower light-blocking plates 7 are located at one end of the accommodating space opposite to the light source plate 8. The first lower light-blocking plate 5 is located between the light source plate 8 and the first diffuser plate 1. The second lower light-blocking plate 6 is located between the light source plate 8 and the back plate 3. The third lower light-blocking plate 7 is provided on both sides of the light source plate 8.
[0031] Combination Figure 3 The frame 2 includes at least one slot 21 and at least one fixing post 22. The slot 21 is located at a first end within the frame 2, and the fixing post 22 is located at a second end within the frame 2. The slot 21 is used to install the upper light-blocking plate 4, which reflects the light projected onto the top downwards, compensating for the weak light on the side of the first diffuser plate 1 and the back plate 3 away from the light source plate 8. The light source plate 8 and the first lower light-blocking plate 5 are sequentially installed on the fixing post 22, and the light source plate 8 is also adjacent to the second lower light-blocking plate 6, which is fixedly mounted on the frame 2. The first lower light-blocking plate 5 and the second lower light-blocking plate 6 can effectively block some of the ineffective light, change the emission angle of the light source, and reflect the light back into the receiving space, thereby mitigating the problem of excessive light on the side of the first diffuser plate 1 and the second diffuser plate closer to the light source.
[0032] like Figure 4 and Figure 5 As shown, preferably, both the first lower light-blocking plate 5 and the second lower light-blocking plate 6 are arranged at an angle α toward the light source plate 8, where the angle α is 0° to 14°. More preferably, the angle α is 10°.
[0033] Furthermore, such as Figure 3 As shown, both the first lower light-blocking plate 5 and the light source plate 8 have fixing holes 51 and 81, in which the fixing post 22 is installed. The first lower light-blocking plate 5 and the light source plate 8 are mounted on the fixing post 22 through the fixing holes 51 and 81. Furthermore, the first lower light-blocking plate 5 also has a groove 52, which fits into the frame 2. The light source plate 8 and the second lower light-blocking plate 6 are both set at an angle α. Several light sources 82 and communication indicator lights 83 are provided on the side of the light source plate 8 near the third lower light-blocking plate 7 (see...). Figure 6 The light source 82 provides stable, visible light, and the communication indicator light 83 reflects the communication status of the device. The light source board 8 also has a light-transmitting hole 84 for the communication indicator light 83. It is worth noting that the light source board 8 also functions as a control board.
[0034] The second lower light-blocking plate 6 has a third lower light-blocking plate 7 on both sides, and the third lower light-blocking plate 7 is fixedly mounted on the frame 2. Preferably, the third lower light-blocking plate 7 is positioned at an angle β toward the light source plate 8, and the angle β is 0° to 14°. More preferably, the angle β is 10°.
[0035] In this embodiment, the sign light is installed by suspension. The frame 2 is also equipped with a mounting bracket 23, which is located at the top of the frame 2. The mounting bracket 23 enables the sign light to be suspended. Furthermore, the frame 2 is equipped with a wire groove 24, in which wires are installed.
[0036] In this embodiment, the back plate 3 is a second diffuser plate. Both the first diffuser plate 1 and the second diffuser plate are processed with marking patterns, which can be achieved through ink printing, attaching printed plastic sheets, or using perforated patterned sheets. The first diffuser plate 1 also has a communication light-transmitting hole 11 to ensure that the wireless communication function between the marker light and external devices is not obstructed.
[0037] During assembly, the light source plate 8 with wires is first installed on the fixing post 22 of the frame 2 through the fixing hole 81, and the wires are sequentially inserted into the wire groove 24. The two sides of the upper light-blocking plate 4 are inserted into the slot 21, and then the first lower light-blocking plate 5 is installed on the fixing post 22 through the fixing hole 51. The first diffuser plate 1 and the second diffuser plate are then fixed using ultrasonic welding or adhesive bonding. After assembly, the sign light is suspended in the usage scenario using the mounting component 23. The blocking and reflection of light by the upper light-blocking plate 4, the first lower light-blocking plate 5, the second lower light-blocking plate 6, and the third lower light-blocking plate 7 makes the light distribution within the sign light wall more uniform, thereby solving the problem of uneven sign light effect.
[0038] Example 2
[0039] This embodiment provides a sign light that can be wall-mounted, combined with... Figure 3 and Figure 7 As shown, compared with Embodiment 1, this embodiment does not include the second lower light-blocking plate 6, the third lower light-blocking plate 7, the second diffuser plate, or the mounting component 23.
[0040] Combination Figure 7 As can be seen, in this embodiment, the frame 2 is provided with mounting holes 25, which are used for wall mounting.
[0041] In this embodiment, the wire groove 24 is provided at the location where the light source plate 8 is installed on the frame 2, and the wire is reserved in the wire groove 24.
[0042] In addition, combined Figure 8 The back plate 3 is not a diffuser plate, and the back plate 3 is provided with a lead hole 31, through which the wire passes.
[0043] During assembly, the light source plate 8 with wires is installed on the fixing post 22 of the frame 2 through the fixing hole 81, and the wires are sequentially inserted into the wire groove 24. The two sides of the upper light-blocking plate 4 are inserted into the slot 21, and then the first lower light-blocking plate 5 is installed on the fixing post 22 through the fixing hole 51. Finally, the first diffuser plate 1 and the back plate 3 are fixed using ultrasonic welding or adhesive bonding. After assembly, the sign light is wall-mounted in the usage scenario using the mounting hole 25.
[0044] The first lower light-blocking plate 5 is tilted towards the light source plate 8 at a 0°–14° angle, preferably 10°. The first lower light-blocking plate 5, together with the upper light-blocking plate 4, blocks and reflects the light, making the light distribution within the sign light wall more uniform, thereby solving the problem of uneven sign light effect.
[0045] In summary, this utility model provides a sign light. By installing the first lower light-blocking plate 5 on the frame 2 and setting the first lower light-blocking plate 5 at an angle of 0° to 14°, it effectively blocks some of the ineffective light from the LED beads, changes the light emission angle of the LED beads, and reflects the light into the sign light cavity, thereby effectively mitigating the problem of excessive light on the side of the diffuser plate close to the LED beads. Furthermore, the upper light-blocking plate 4 located in the slot 21 reflects the light projected to the top downwards, compensating for the weak light on the side of the diffuser plate away from the LED beads. This utility model, through the combined blocking and reflection of light by the upper and lower light-blocking plates, makes the light distribution within the sign light cavity more uniform, ensuring uniform luminous efficacy of the indicator sign.
