[0035] The embodiments of the present application will be described in detail by specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present application from the disclosed content of the specification. Obviously, the described embodiments are part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.
[0036] Please refer to Figures 1-5 , a kind of quick heat dissipation energy-saving down lamp suitable for subway tunnel disclosed by the present application will be described, the present application has eight parts, such as Figure 1 , including hoisting support 1, built-in power supply 2, heat transfer support plate 3, LED lamp 4, connecting assembly 5, heat dissipation plate 6, mounting shell 7 and cover plate 8, the mounting shell 7 upper end is provided with cover plate 8, hoisting support 1 is installed on the upper surface of cover plate 8, connecting assembly 5 is installed in mounting shell 7, LED lamp 4 is installed in connecting assembly 5, heat dissipation plate 6 is installed on the upper end of connecting assembly 5, heat dissipation plate 6 upper end is provided with heat transfer support plate 3, heat transfer support plate 3 is arranged in pairs, built-in power supply 2 is installed between two heat transfer support plates 3.
[0037] When using the present invention, first select the LED lamp 4, install the LED lamp 4 in the connecting assembly 5, then select the diffusion plate 51 for this lighting condition according to the lighting condition of the LED lamp 4, then put the waterproof ring 53 on the outer side of the upper end of the diffusion plate 51, and after putting it on, install the diffusion plate 51 into the flange. When placed, the bottom edge of the diffusion plate 51 faces the opening direction of the inner cover 54, and after the diffusion plate 51 is installed, the outer surface of the waterproof ring 53 will be against the inner surface of the flange, at this time, the diffusion plate 51 and the inner cover 54 can be connected. The sealing of the gap at the connection position of the inner cover 54 can effectively prevent moisture in the air from entering and affecting the brightness of the downlight. Then, several limiting components 52 are installed in the gap between the flange and the diffuser 51. During the installation process of the limiting component 52, the L-shaped block 521 and the limiting block 522 are first brought close to each other, and the limiting spring 523 is compressed to generate elastic force, and then the limiting component 52 is inserted from the gap between the flange and the diffuser 51. After insertion, since the width of the gap is larger than the width of the L-shaped block 521 and the limiting block 522, the limiting component 52 is inserted into the gap between the flange and the diffuser 51. 22, driven by the limit spring 523, the L-shaped block 521 is pushed toward the outer surface of the diffuser plate 51, and the limit block 522 is pushed toward the inner surface of the flange. After the L-shaped block 521 and the limit block 522 are respectively pressed, the elastic force of the spring is not completely released. Under the action of the elastic force, the L-shaped block 521 and the limit block 522 are continuously pressed. The setting of the plurality of limit members 52 can effectively limit the diffuser plate 51 in the flange. After the connecting assembly 5 is assembled, the connecting assembly 5 is removed from the installation outer The housing 7 is inserted into the opening at the top of the housing 7. After insertion, the concave structure 72 will press against the connecting assembly 5. Then, the heat sink 6 is installed on the upper end of the connecting assembly 5. After the built-in power supply 2 is installed between the two heat transfer support plates 3, the built-in power supply 2 and the heat transfer support plates 3 are installed on the upper end of the heat sink 6. Then, the LED light 4 and the built-in power supply 2 are connected with wires. After the connection is completed, the sealing silicone ring 9 is installed on the upper end of the flap structure 71, and the cover 8 is placed on the upper end of the sealing silicone ring 9 and the heat transfer support plates 3. Finally, it is fixed with bolts. When the entire downlight is in use, the entire downlight is installed in the connection position using the hanging bracket 1, and the built-in power supply 2 is started to drive the LED light 4 to emit light, thereby completing the lighting of the tunnel.
[0038] In a specific embodiment, Figure 2The connecting assembly 5 comprises a diffusion plate 51, a limiting member 52, a waterproof ring 53 and an inner cover 54. The inner cover 54 is provided with a plurality of limiting members 52 at the bottom. The limiting members 52 and the bottom of the inner cover 54 form an installation space. The outer surface of the bottom of the inner cover 54 abuts against the inner wall of the installation shell 7. The diffusion plate 51 is installed in the installation space. The waterproof ring 53 is sleeved on the outer side of the top end of the diffusion plate 51. The diffusion plate 51 is used to realize the effect of optical diffusion by using the physical phenomenon that light is refracted, reflected and scattered when it encounters two media with different refractive indexes (densities) in the path. This is usually achieved by adding inorganic or organic light diffusers in the base material or by adjusting the light through the array arrangement of the micro features on the surface of the base material, so that the light is refracted, reflected and scattered in different directions, thereby changing the path of the light, achieving sufficient dispersion of incident light, and further achieving the effect of uniform light emission. The limiting member 52 is arranged to solve the problem that different LED lamps 4 require different diffusion plates 51. Different diffusion plates 51 have different diameters and cannot guarantee that the outer surface of each diffusion plate 51 abuts against the inner wall of the flange to limit the diffusion plate 51. Therefore, the limiting member 52 is arranged to limit the diffusion plate 51, thereby preventing the diffusion plate 51 from shifting during the light emission of the LED lamp 4, which causes uneven light emission and affects the lighting of the tunnel. The LED lamp 4 generates a large amount of heat during light emission. The heat causes the water in the air to condense into water droplets. If the water droplets enter the connecting assembly 5, the water droplets will fall on the diffusion plate 51 and form water stains on the diffusion plate 51, which will block the diffusion of light and affect the illumination. The waterproof ring 53 prevents the condensed water droplets from entering the connecting assembly 5.
[0039] In a specific embodiment, as shown in Figure 2 The inner cover 54 is a light reflecting cup structure. The light reflecting cup structure is provided with a flange at the bottom. The outer surface of the flange abuts against the inner wall of the installation shell 7. The outer edge of the waterproof ring 53 abuts against one end of the limiting member 52 and the inner wall of the flange. The light reflecting cup structure can cause the light generated by the LED lamp 4 to be refracted on its surface, so that more light can be emitted. The outer surface of the flange is in contact with the inner wall of the installation shell 7, so that the heat on the inner cover 54 can be dissipated along the installation shell 7, thereby improving the heat dissipation efficiency.
[0040] In a specific embodiment, as shown in Figure 3The limiting member 52 includes an L-shaped block 521, a limiting block 522, a limiting spring 523, and an inclined slot 524. The limiting spring 523 is mounted on one end of the L-shaped block 521, which is positioned below the waterproof ring 53. The limiting block 522 is mounted on the other end of the limiting spring 523. The outer surface of the limiting block 522 abuts against the inner wall of the flange, and the inclined slot 524 is provided on the side wall of the limiting block 522. The two sides of the L-shaped block 521 respectively contact the bottom and side surfaces of the diffuser plate 51. Under the action of the elastic force of the limiting spring 523, the L-shaped block 521 and the limiting block 522 are continuously pushed, thereby limiting the position of the diffuser plate 51. The inclined slot 524 is provided to guide the installation.
[0041] In a specific embodiment, Figure 4 The bottom of the mounting housing 7 is provided with a concave structure 72, the top of which abuts against the bottom of the connecting assembly 5. The top of the mounting housing 7 is provided with a flap structure 71 perpendicular to the side panels of the mounting housing 7. The concave structure 72 not only supports and mounts the connecting assembly 5, but also allows the diffuser 51 to move away from the bottom of the connecting assembly 5, thereby preventing glare.
[0042] In a specific embodiment, Figure 5 The cover plate 8 includes a wire outlet waterproof buckle 81, a plate body 82, a connecting block 83, and a threaded hole 84. The connecting block 83 is mounted on the bottom surface of the plate body 82. The connecting blocks 83 are arranged in pairs and have threaded holes 84 formed in the connecting blocks 83. The threaded holes 84 extend to the plate body 82. The wire outlet waterproof buckle 81 is mounted on the plate body 82. A sealing silicone ring 9 is installed at the connection between the plate body 82 and the mounting housing 7. The waterproof buckle 81 can achieve a waterproof and dustproof effect. The threaded hole 84 is used to install a bolt, so that the hanging bracket 1 can be installed on the plate body 82. The sealing silicone ring 9 has the same effect as the waterproof ring 53, also preventing water droplets from entering. The fixing bolts run along the plate body 82 and pass through the silicone ring 9 and the flap structure 71 in sequence.
[0043] In one specific embodiment, the heat sink 6 and the heat transfer support plate 3 are U-shaped, and both are made of metal. The U-shaped structure provides a larger contact area between the heat receiving and heat dissipating ends, further improving heat dissipation efficiency. Metal has excellent thermal conductivity, further enhancing heat transfer and heat dissipation efficiency.
[0044] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
