Description

Technical Field

[0001] The present invention relates to an indicator light, and more particularly to a structural improvement of an indicator light for platform doors. Background Art

[0002] The existing platform door indicator lights are a row of indicator lights installed on the platform doors, and each movable platform door is equipped with an indicator light. The door opening control system simultaneously controls the door opening mechanical device and the indicator light. Therefore, passengers can judge the movement state of the movable platform door by observing the on / off or flashing of the indicator light, which plays a role in indicating the opening and closing of the platform door and faults.

[0003] In addition, as a device for indicating door opening and closing and faults, the platform door indicator light generally has a light bulb, or may have multiple light bulbs, and is additionally provided with linkage accessories such as a buzzer, a broadcast speaker, and a fault reporting device. Such linkage accessories for strengthening its indication ability do not exceed the actual functions of the platform door indicator light as a device for indicating the opening and closing of the platform door and faults.

[0004] The light-emitting light source of the existing platform door indicator light is generally one or more light bulbs installed in a lamp shade. The light bulb lights up and goes out with the power supply of the connected wire. The visual effect of the indicator light mainly depends on the light source of the light bulb illuminating the lamp shade from the inside outwards. Its visual art value is limited to the design of the lamp shade, which makes the shapes of the existing platform door indicator lights identical, and the visual design is restricted by the bottleneck of the lamp shade design, and it is impossible to further develop a new type of platform door indicator light with higher visual art value.

[0005] Therefore, it is necessary to develop a platform door indicator light that does not require a lamp shade and does not use a light bulb style for the light source, so as to break through the visual design limitations of the existing platform door indicator lights.

[0006] Another existing light-emitting device is a fiber optic lighting system, which consists of a light source and optical fibers. The light source forms a beam of approximately parallel light, and a color filter can also be added to turn the beam into colored light. When the beam enters the optical fiber, the colored light is sent to a predetermined place along the path of the optical fiber.

[0007] The color filter is a part that changes the color of the light beam. According to needs, corresponding colored light sources can be obtained by replacing different color filters.

[0008] The optical fiber is the main body in the fiber optic lighting system. The function of the optical fiber is to transmit or emit light to a predetermined place. The optical fiber is divided into two types: end-emitting and body-emitting. In the former case, after the light beam reaches the end point, it is illuminated through a tail light, while in the latter case, it is itself a light-emitting body, forming a flexible light column.

[0009] Optical fibers are available in single-strand, multi-strand, and mesh types. The diameter of single-strand optical fibers ranges from Ф6 to Ф20 mm. The diameter of multi-strand optical fibers is generally from Ф0.5 to Ф3 mm, and the number of strands commonly ranges from several to hundreds. Mesh optical fibers are composed of thin-diameter volume-emitting optical fibers and can form flexible light strips.

[0010] Optical fibers are polymerized from liquid polymer compounds and have the characteristics of strong light conductivity, power saving, durability, no heat generation, no pollution, bendability, color changeability, a wide range of environmental adaptability, and safe use. The light guiding methods of optical fibers are divided into soft and warm line-light optical fibers and shining point-light optical fibers, and they are widely used in various decorative lighting projects such as building decoration lighting, landscape decoration lighting, lighting for cultural relics and handicrafts, lighting for special occasions, billboards, and entertainment venues.

[0011] It can be seen that the optical fiber lighting system has many advantages, but in the existing technology, there is no technical solution to apply this optical fiber lighting system to platform door indicator lights. Summary of the Invention

[0012] The technical problem to be solved by the present invention is to provide a platform door optical fiber indicator light system that does not require a lamp shade and does not use a bulb-like light source, so as to break through the visual design limitations of existing platform door indicator lights.

[0013] The technical solution of the present invention is as follows: A platform door optical fiber indicator light system includes: a platform door control unit and a platform door body;

[0014] It further includes: a light source machine controlled by the platform door control unit for emitting an optical fiber light source, a conversion disk, a turntable motor for driving the conversion disk to rotate, and several bundles of optical fibers;

[0015] At least a part of the structure of the platform door body uses a light-transmitting material;

[0016] The conversion disk is installed at the light outlet of the light source machine, and several openings are provided thereon, and each opening is respectively connected to a bundle of the optical fibers;

[0017] One end of each bundle of the optical fibers is connected to the conversion disk, and the other end is connected to the platform door body;

[0018] The platform door control unit controls the conversion disk to rotate through the turntable motor until a certain opening is aligned with the light outlet of the light source machine, so that the light emitted by the light source machine is transmitted through the optical fibers and finally transmitted out through the platform door body.

[0019] Different bundles of optical fibers are arranged on the platform door body to present different words and / or graphics.

[0020] Preferably, color filters are provided at the end faces of each bundle of optical fibers on the conversion disk, and the colors of these color filters are different from each other.

[0021] Each of the optical fibers is a single optical fiber or a bundle of multiple optical fibers.

[0022] Compared with the prior art, the platform door optical fiber indicator system of the present invention creatively improves the optical fiber lighting technology and specifically applies it to the platform door indicator. Through the light source machine and the turntable motor driving the switching disc, optical fiber bundles with different arrangements are presented on the light-transmitting door body of the platform door, enabling the platform door to emit light not by a fixed-point light source of a light bulb but by multiple bundles of optical fibers arranged freely at positions on the light-transmitting door body of the platform door. The light-emitting points can arbitrarily arrange various patterns or words in the light-transmitting area of the entire platform door body, and can also be controlled to change color and controlled to switch patterns or words; the indicator of the present invention does not require a lampshade, and the light source does not adopt the style of a light bulb, subverting the technical route of the traditional light bulb light source type platform door indicator, breaking through the visual design limitations of the existing platform door indicator, and enhancing the overall visual art value of the platform door.

[0024] Figure 2 It is a schematic diagram of the components through which the optical path of the platform door optical fiber indicator system of the present invention passes. Detailed Embodiments

[0025] The present invention will be further described in detail below in conjunction with the embodiments and the drawings.

[0026] As Figure 1 and Figure 2 shown, the platform door optical fiber indicator system of the present invention includes: a platform door control unit 1, a light source machine 2, a switching disc 3, a turntable motor 4, several bundles of optical fibers 5, and a platform door body 6. In this embodiment, the platform door control unit 1, the light source machine 2, the switching disc 3, and the turntable motor 4 are installed in a platform door base 8 below the platform door body 6.

[0027] Among them, the platform door control unit 1 is a standard electrical control component and serves as a control signal source. The present invention only proposes to use the platform door control unit 1 as the control signal source and does not involve the design inside the platform door control unit 1. The platform door control unit 1 controls the light source machine 2, the turntable motor 4, and the platform door body 6.

[0028] The light source machine 2 is a standard optical fiber light source machine and serves as the light source of the optical fiber indicator. The present invention only proposes to use the light source machine 2 as the light source and does not involve the design inside the platform door control unit 1.

[0029] The conversion disk 3 is in the shape of a partial disk in this embodiment and is rotatably installed at the light outlet of the light source machine 2. A number of openings 31 are formed thereon, and each opening 31 is respectively docked with a fiber optic cable 5.

[0030] The turntable motor 4 is a motor, and its motor shaft is connected to the rotating shaft of the conversion disk 3, and is used to drive the conversion disk 3 to rotate, so that the end faces of the fiber optic cable bundles at the openings 31 on the conversion disk 3 sequentially pass through the light outlet of the light source machine 2.

[0031] Each fiber optic cable 5 can be a single fiber optic cable or a bundle of multiple fiber optic cables. One end thereof is docked with a certain opening 31 on the conversion disk 3, and the other end is docked with the platform door body 6.

[0032] The platform door body 6 can be a single platform door or can include multiple platform doors. At least a part of the structure of each platform door uses a light-transmitting material.

[0033] The platform door control unit 1 controls the conversion disk 3 to rotate to a certain opening 31 to align with the light outlet of the light source machine 2 through the turntable motor 4, so that the light emitted by the light source machine 2 is transmitted through the fiber optic cable and finally transmitted through the platform door body 6, thereby presenting a light-emitting effect that can be observed by the waiting passengers on the platform.

[0034] Different bundles of fiber optic cables 5 can be arranged on the platform door body 6 to present different words and / or graphics, so that the platform door control unit 1 can control the switching of the graphics and / or words displayed on the platform door body 6.

[0035] In a possible implementation manner, when the train arrives at the station, the platform door is controlled by the platform door control unit 1 to open the corresponding sliding door. At the same time, the platform door fiber optic indicator light system of the present invention is also controlled by the platform door control unit 1 to start the light source machine 2. In addition, in various situations such as when the train enters the station, leaves the station, passes through the station, and the platform door fails, the platform door control unit 1 will send different action signals to the turntable motor 4 to make the turntable motor 4 rotate the conversion disk 3 to several specific positions, so that the light outlet of the light source machine 2 is aligned with a specific opening 31 on the conversion disk 3 where the end face of the fiber optic cable bundle is fixed. Each signal corresponds to a specific bundle of fiber optic cables 5 on the conversion disk 3, and the other end of each fiber optic cable 5 is connected to the platform door body 6. Each fiber optic cable 5 presents different fiber optic cable arrangement modes on the light-transmitting material of the platform door body 6 according to its corresponding indication state. For example but not limited to, the end of the fiber optic cable bundle corresponding to the door opening signal can arrange the word "Open the Door" on the platform door body 6, and the fiber optic cable corresponding to the door closing signal is arranged in the word "Close the Door".

[0036] Preferably, color filters may also be provided at the end faces of each optical fiber 5 on the conversion disk 3, and the colors of these color filters are different from each other. Thus, the act of switching the optical fiber bundles by the conversion disk 3 can not only change the spatial arrangement effect of the optical fiber bundles, but also change the color of light.

[0037] According to different indication status signals received from the platform screen door control unit 1, on the one hand, the platform screen door optical fiber indicator system of the present invention can control the on / off of the light source machine 2, and on the other hand, it can control the turntable motor 4 to drive the conversion disk 3 to switch the optical fiber bundles presenting different arrangement modes on the platform screen door light-transmitting material. Thus, a more diversified lighting design effect than that of the traditional bulb light source can be achieved, effectively enhancing the visual value appreciation space of the platform screen door indicator lamp.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
