Description

Technical Field

[0001] This application relates to the field of railway signal light technology, and in particular to a disc-type LED light for subway use. Background Technology

[0002] In subway transportation systems, signal controllers play a crucial role in ensuring the safe and orderly operation of trains. As a core component of these signal controllers, the performance of LED light-emitting panels directly affects the clarity and reliability of signal displays. With the continuous expansion of subway construction and technological advancements, higher demands are being placed on LED light-emitting panels for signal controllers. Against this backdrop, the project for miniaturized LED light-emitting panels specifically designed for subways has emerged. During the use of LED lights, if there are small stones or debris on the tracks, the subway train will cause these objects to fly up, potentially impacting the LED bulbs and causing them to malfunction. Utility Model Content

[0003] The purpose of this utility model is to provide a disc-type LED light for subway use, addressing the shortcomings and deficiencies of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The device includes a housing and an LED bead. The LED bead is located inside one end of the housing. The housing has a baffle portion on the outside of the end near the LED bead. The baffle portion covers the LED bead. The baffle portion includes a connecting ring and a baffle rope. The baffle rope is located inside the connecting ring and is arranged in a mesh pattern.

[0005] Preferably, one end of the housing is fitted with an installation ring, and the connecting ring is disposed on the inner peripheral sidewall of the installation ring.

[0006] Preferably, the mounting ring is semi-circular.

[0007] Preferably, one end of the mounting ring is rotatably connected to the side wall of the housing, and a fixing member is provided between the other end of the mounting ring and the housing, the fixing member being able to connect and install the mounting ring to the housing.

[0008] Preferably, the fixing component includes an adjusting bolt, a fixing block, and a fixing hole. The fixing block is disposed at one end of the adjusting bolt, and the other end of the adjusting bolt is threaded to the side wall of the housing. The fixing hole is opened in the side wall of the mounting ring, and the fixing block is inserted into the fixing hole.

[0009] Preferably, the inner circumferential sidewall of the mounting ring is provided with a limiting groove, and the sidewall of the connecting ring is inserted and fixed in the limiting groove.

[0010] Preferably, the side wall of the connecting ring is provided with an embedding groove, a locking rod is inserted and slidably inserted in the embedding groove, a compression spring is provided between the locking rod and the bottom of the embedding groove, the mounting ring is provided with a limiting hole in the side wall of the limiting groove, and the compression spring drives the locking rod to slide in the embedding groove and allows one end of the locking rod to be inserted into the limiting hole.

[0011] In summary, this application includes at least one of the following beneficial technical effects: 1. After the LED light is assembled, the baffle is located at one end of the housing and covers the LED light. When external impurities fly towards the LED light, the LED beads will not be impacted by the baffle, thus improving the lifespan of the LED light. 2. When the blocking rope of the blocking part is damaged and the blocking part needs to be replaced, push the locking rod to disengage one end of the locking rod from the limiting hole, and at the same time compress the compression spring. Then the connecting ring can slide out of the limiting ring groove, thereby removing the connecting ring from the mounting ring. After that, install the complete blocking part on the mounting ring, which improves the convenience of replacing the blocking part. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] This application discloses a disc-type LED light for subway use.

[0016] Reference Figure 1The device includes a housing 1 and LED beads 2. The LED beads 2 are installed inside one end of the housing 1. A mounting ring 3 is rotatably connected to the outer side of one end of the housing 1. The mounting ring 3 is semi-circular in shape, and a baffle 4 is provided on the inner circumference of the mounting ring 3. The baffle 4 includes a connecting ring 5 and a baffle rope 6. The baffle rope 6 is located inside the connecting ring 5 and is arranged in a mesh pattern. The baffle 4 is located at one end of the housing 1 and covers the LED lamp. When external impurities fly towards the LED lamp, the LED beads will not be impacted by the action of the baffle 4.

[0017] Reference Figure 2 and Figure 3 One end of the mounting ring 3 is rotatably connected to the housing 1. The other end of the mounting ring 3 is provided with a fixing member 7 between it and the housing 1. The fixing member 7 includes an adjusting bolt 8, a fixing block 9, and a fixing hole 10. The fixing block 9 is disc-shaped. The fixing hole 10 is opened on the outer side wall of one end of the mounting ring 3. The mounting ring 3 has a connecting hole 11 at the bottom of the fixing hole 10. The side wall of the housing 1 has a threaded hole 12, which can correspond to the connecting hole 11.
