Description
Technical Field
[0001] This utility model belongs to the field of lighting optics technology, specifically relating to a novel lens assembly and an emergency downlight. Background Technology
[0002] The lens on a lamp acts as an intermediary between the internal and external parts. When light from the lamp shines onto the lens, it is reflected back to the external environment, thus achieving the lighting effect.
[0003] In existing lighting fixtures, the lens is installed from the inside out, with the top of the lens fixed inside the fixture and the bottom of the lens located outside. The lens is wider at the top and narrower at the bottom, and it is clamped inside the fixture. When replacing the lens, the fixture needs to be opened, the lens removed from inside the fixture, and a new lens installed before assembling the fixture.
[0004] Alternatively, some light fixtures require the use of a screwdriver to unscrew multiple screws on the lens, then remove the old lens and install the new lens, and then reverse the process to tighten the screws, making the whole process cumbersome.
[0005] Both of these structures require disassembling the light fixture for operation, which is not only time-consuming but also demands a high level of professional skill from the operator, making them inconvenient to use. Therefore, there is an urgent need for a lens structure that is easy to replace in the light fixture. Summary of the Invention

Detailed Implementation
[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments;
[0034] This embodiment provides a novel lens assembly, including a lamp housing 01. The lamp housing 01 is integrally formed and can be square or cylindrical depending on the requirements. The interior of the lamp housing 01 is recessed and hollow. A first through hole 010 is provided on the bottom surface of the lamp housing 01. The opposite two sides of the first through hole 010 extend outward to form a fan-shaped second through hole 011. The outer edge of the second through hole 011 is recessed to form an arc-shaped first retaining strip 0110. A first notch 0111 is provided on the inner wall of one end of the first retaining strip 0110. The second through hole 011 is used for rotational positioning, the first retaining strip 0110 forms a staggered layer to serve as an overlap, and the first notch 0111 is used for insertion.
[0035] It also includes a face cover 02, which is plate-shaped; a first mounting hole 020 is opened in the middle of the face cover 02, and first male buckles 021 protrude from both sides of the first mounting hole 020, with the guide angles of the two first male buckles 021 facing away from each other.
[0036] It also includes lens 03, the bottom surface of lens 03 is arc-shaped, the top surface of lens 03 is concave to form a first pit 030, and the top sidewall of lens 03 protrudes outward to form an annular first baffle 031.
[0037] The bottom of the lens 03 passes through the first mounting hole 020 of the cover 02. The cover 02 is stacked with the first baffle 031. The first male buckle 021 of the cover 02 is inserted into the first notch 0111 of the lamp housing 01. The cover 02 rotates and the guide angle is fixed on the first locking strip 0110.
[0038] The first baffle 031 is clamped and fixed between the lamp housing 01 and the panel.
[0039] As described above, in the specific usage process, the bottom of the lens 03 is passed through the first mounting hole 020 of the faceplate 02, so that the faceplate 02 and the first baffle 031 on the top of the lens 03 are stacked together. The assembled faceplate 02 and lens 03 are aligned with the lamp housing 01, and the first male buckle 021 of the faceplate 02 is aligned with the first notch 0111 on the inner wall of the end of the first retaining strip 0110 of the lamp housing 01, and the first male buckle 021 is inserted.
[0040] Rotate the cover 02. The rotating strip 022 on the lower surface of the cover 02 assists in the rotation operation. The guide angle of the first male buckle 021 on the cover 02 gradually overlaps with the first locking strip 0110. As the rotation proceeds, the first male buckle 021 moves along the first locking strip 0110 until the cover 02 is securely installed on the lamp housing 01. At this time, the first baffle 031 is tightly clamped between the lamp housing 01 and the panel, completing the assembly of the new lens 03 assembly.
[0041] To replace lens 03, reverse the process: flip faceplate 02, remove the old lens 03, and replace it with the new lens 03.
[0042] Furthermore, the inner wall of the first through hole 010 is curved and fits against the surface of the lens 03.
[0043] As mentioned above, this design helps to better fit lens 03 and improve stability.
[0044] Furthermore, the upper surface of the other end of the first card strip 0110 is recessed to form a first step 0112, and the upper surface of the first step 0112 is connected to the upper surface of the first card strip 0110 by a slope transition.
[0045] As described above, the first step 0112 limits and fixes the first male buckle 021, and the sloping transition facilitates the smoother engagement of the cover 02 with the first locking strip 0110 during installation and rotation.
[0046] Furthermore, two parallel rotating strips 022 protrude from the lower surface of the cover 02.
[0047] As mentioned above, during installation, the rotating bar 022 allows two fingers to easily press against the rotating cover 02, making the installation operation more convenient.
[0048] Furthermore, at least two limiting posts 032 protrude from the top surface of the lens 03; the limiting posts 032 are integrally formed with the lens 03.
[0049] Limiting holes 041 are provided around the LED beads 040 on the LED light board 04. The LED beads 040 are placed in the first recess 030, and the limiting post 032 is inserted into the limiting hole 041 for fixation.
[0050] As described above, the LED light panel 04 and the lens 03 are assembled facing each other, and the limiting post 032 is inserted into the corresponding limiting hole 041 to ensure that the relative position of the lens 03 and the LED light panel is accurate and to ensure the effect of light passing through the lens 03.
[0051] Furthermore, a threaded hole 012 is provided around the first through hole 010 on the lamp housing 01;
[0052] The bolt passes through the LED light panel 04 and is connected and fixed to the threaded hole 012.
[0053] As described above, bolts are used to securely connect the LED light board to the lamp housing 01, and the rotation of the cover 02 does not affect the position of the LED light board 04.
[0054] During assembly, the LED light board 04 is placed on the bottom surface of the lamp housing 01, so that the LED beads 040 on the LED light board 04 correspond to the positions of the first through hole 010 on the lamp housing 01. Bolts are used to pass through the corresponding holes on the LED light board 04 and connect them to the threaded holes 012 around the first through hole 010 on the lamp housing 01. The bolts are tightened to fix the LED light board 04 on the lamp housing 01.
[0055] Next, the limiting post 032 on the top surface of the lens 03 is accurately inserted into the limiting hole 041 around the lamp bead 040 on the LED light board 04 to ensure that the relative position of the lens 03 and the LED light board 04 is accurate.
[0056] An emergency downlight, comprising the novel lens 03 assembly described above;
[0057] It also includes a lamp cover 05, which is connected and fixed to the top of the lamp housing 01, covering the interior of the lamp housing 01. The lamp cover 05 protects the interior of the lamp housing 01. As shown in the figure, the lamp housing 01 is cylindrical, and the lamp cover 05 is disc-shaped, with electronic components installed inside. The two are connected by covering each other.
[0058] Furthermore, a second mounting hole 013 is provided on the top of the side wall of the lamp housing 01; a second male buckle 050 protrudes from the edge of the lamp cover 05, and the guide angle of the second male buckle 050 is embedded in the second mounting hole 013 for fixation.
[0059] As mentioned above, the lamp cover 05 and the lamp housing 01 are connected by a snap-fit mechanism, which allows for easy disassembly.
[0060] In another embodiment, the screw passes through the side wall of the lamp housing 01 and is threaded to the lamp cover 05, so that the lamp cover 05 is tightly connected to the lamp housing 01, thereby improving the overall protective performance of the emergency downlight.
