Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a low-voltage safety lamp. Background Art

[0002] Tunnel lights (standardly called low-voltage safety lights) for lighting need to be installed in the maintenance tunnel to facilitate daily maintenance of the subway and vehicle depot. Specifically, when the vehicle is being repaired, it will be parked above the tunnel, and personnel will repair the vehicle in the tunnel. Low-voltage safety lights are installed on both side walls of the tunnel for lighting.

[0003] In order to improve the sealing of the shell and reduce the intrusion of water vapor and dust into the low-voltage safety lamp through the gap between the shell and the mask, there are two common practices in the market: First, the shell 1 is made of aluminum profile, and the mask 2 is made of silk-screen black-edged tempered glass, and the tempered glass is glued to the shell 1 with glass glue 91 to achieve dust and water proof effect of the shell, such as Figure 1 As shown, the disadvantage of this structure is that the tempered glass of the mask needs to be silk-screened with black borders on both sides of the glass to cover the glass glue, otherwise it will be ugly. Tempered glass is more expensive than plastic diffuser plates, and the silk-screen process cost is even higher. In addition, after the tempered glass is glued, the low-voltage safety lamp needs to be moved to an idle place and placed for a period of time to wait for the glue to solidify, which affects the production efficiency of the assembly line and wastes labor hours. Second, the shell 1 is made of aluminum profiles, and the mask 2 uses a plastic diffuser plate. The silicone waterproof strip 93 is squeezed by the pressure strip 92 to achieve the dust and water proof effect of the shell, such as Figure 2 As shown, the disadvantages of this structure are high material cost, the layering strips need special machines to be pressed in, high processing costs and low production efficiency.

[0042] Example 1

[0043] Please refer to Figures 3 to 6, Embodiment 1 of the present invention is: a low-voltage safety lamp, comprising a shell 1, a mask 2 and a waterproof rib 3, the shell 1 comprising a bottom plate 11 and two side plates 12 arranged oppositely, the two side edges of the bottom plate 11 are respectively connected to the two side plates 12, the inner walls of the side plates 12 have a locking rib 121 and a locking groove 122, and the locking groove 122 is located above the locking rib 121; the mask 2 comprises a panel 21 and a vertical wall 22 arranged oppositely, the vertical wall 22 is connected to the panel 21, and the lower part of the vertical wall 22 is provided with a clamping head 221 that cooperates with the locking rib 121; the hardness of the waterproof rib 3 is less than the hardness of the mask 2, and the outer wall of the vertical wall 22 is provided with a plurality of waterproof ribs 3, the waterproof ribs 3 abut against the inner wall of the side plate 12, at least two of the waterproof ribs 3 extend in different directions to form an eight-shaped shape, and the end of at least one waterproof rib 3 extends into the locking groove 122.

[0044] In this embodiment, the housing 1 is an aluminum extrusion structure, the mask 2 is made of PC, and is a milky white, translucent mask. The waterproof ribs 3 are made of TPE. For ease of processing and production, the mask 2 and waterproof ribs 3 are preferably co-extruded into a one-piece structure. PC has high diffusion, high light transmittance, and high strength, making it suitable for use as a translucent mask 2 and a load-bearing member. TPE has excellent sealing properties and is stronger than silicone, but much softer than PC, making it deformable but incompressible.

[0045] In this embodiment, three waterproof ribs 3 are connected to the vertical wall 22. The waterproof rib 3 at the bottom extends obliquely downward, and its end extends into the locking groove 122. The other two waterproof ribs 3 extend obliquely upward. In one or more embodiments, the number of waterproof ribs 3 on the vertical wall 22 can also be two, four, five, or more.

[0046] When the integrated structure of the mask 2 and the waterproof ribs 3 is pressed downward into the housing 1, the two waterproof ribs 3 near the top are squeezed and deformed upward. Due to the strength of the TPE material itself, the two waterproof ribs 3 are tightly attached to the inner wall of the side panel 12 after being deformed, achieving a waterproof effect. The waterproof ribs 3 near the bottom are squeezed and deformed, tightly contacting the top surface of the locking rib 121, and the ends are embedded in the locking grooves 122, thus achieving a good sealing effect. At the same time, the clamping head 221 is hooked on the locking rib 121, thereby effectively holding the mask 2 and the housing 1.

[0047] The low-voltage safety lamp also includes an LED light source assembly 4 arranged on the inner side of the base plate 11. In this embodiment, the LED light source assembly 4 includes a circuit board and LED lamp beads arranged on the circuit board. To facilitate processing and production, the driver 5 for driving the LED light source assembly 4 is integrated on the circuit board.

[0048] The low-voltage safety lamp also includes a sealed end cap assembly, which includes an end cap 61 and a sealing gasket 62. One side of the sealing gasket 62 contacts the end of the mask 2 and the end of the housing 1. The end cap 61 is connected to the housing 1 by screws 7, and the end cap 61 contacts the sealing gasket 62. The sealing gasket 62 can be a waterproof silicone ring or the like.

[0049] In this embodiment, a reinforcement groove 123 is provided on the side panel 12. The cross section of the reinforcement groove 123 is arc-shaped. The end of the reinforcement groove 123 is provided with a thread that cooperates with the screw 7. The reinforcement groove 123 can be bent or extruded.

[0050] In one or more embodiments, a bracket 8 is further provided at the bottom of the housing 1 , and preferably, the housing 1 is rotatable relative to the bracket 8 .

[0051] The above are only optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
