Description

Technical Field

[0001] The utility model belongs to the technical field of downlights, and particularly relates to a downlight that can avoid the siphon effect. Background Technique

[0002] With the progress of society, LED downlight lighting has gradually become the mainstream in the field of indoor lighting. At present, all LED downlights are required to have good waterproof functions, and the front face waterproof requirement meets the IP65 level.

[0003] However, in the actual application process, due to the need for waterproofing, the lamp body has a sealed cavity. Then, the heat generated when the lamp beads are lit will cause the air in the lamp body to expand, resulting in the air inside the lamp body being discharged from the weak points, such as the gaps between wires, etc.; when the lamp beads are extinguished or encounter water, the temperature inside the lamp body decreases, the air contracts, resulting in a negative pressure inside the lamp body, and the air intake speed between the wires is slow, so water will enter the lamp body from other weak points, such as the connection between the lens and the radiator, etc., forming a siphon effect, reducing the waterproof effect of the downlight and posing a safety risk. Content of the Utility Model

[0004] The purpose of the utility model is to provide a downlight that can avoid the siphon effect to solve the problems raised in the above background technique. A downlight that can avoid the siphon effect provided by the utility model has the characteristics of quickly balancing the pressure difference inside and outside the lamp body, avoiding the siphon effect problem, enhancing the waterproof effect, and avoiding affecting the safety of users.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A downlight that can avoid the siphon effect includes an outer shell body, a driver is connected above the outer shell body, a lamp body is connected inside the outer shell body, and a face ring is connected below the lamp body. Among them, a silica gel sleeve is connected between the heat dissipation shell of the lamp body and the driving lower cover of the driver, and the silica gel sleeve connects the internal cavity of the lamp body and the internal cavity of the driver. One end of the wire is connected to the light source board inside the lamp body, and the other end of the wire passes through the silica gel sleeve and is connected to the driving board inside the driver.

[0006] In order to achieve the sealed waterproof between the silica gel sleeve and the heat dissipation shell, further, the silica gel sleeve is connected to the heat dissipation shell by interference fit.

[0007] In order to make the heat dissipation shell rotatable so as to adjust the irradiation direction, further, the lamp body further includes a mounting bracket. The mounting bracket is of a "C" - shaped structure, and both ends of the mounting bracket are respectively connected to both sides of the heat dissipation shell by screws.

[0008] To enable quick assembly and disassembly of the outer ring, the face ring further includes an outer ring, with two symmetrical connecting arms on the upper part of the outer ring. The two connecting arms are respectively provided with slots with opposite opening directions, and the mounting bracket is provided with a locking block corresponding to the slot.

[0009] In order to enable the assembly of the inner ring and the outer ring, and to allow the inner ring to be assembled and disassembled together with the outer ring, the ring further includes an inner ring with symmetrical inserts on its circumference and slots corresponding to the inserts on the connecting arm.

[0010] In order to enable the inner ring to rotate together with the heat sink, both the slot and the plug are arc-shaped, and the arc length of the plug is less than the arc length of the slot.

[0011] To further enable adjustment of the overall lamp color temperature, a DIP switch is also installed inside the heat sink housing.

[0012] To further ensure a waterproof seal between the DIP switch and the lens, a silicone sleeve is fitted over the DIP switch.

[0013] To protect the building mounting surface from damage and to achieve a seal between the outer casing and the mounting surface to prevent moisture from entering, a silicone pad is further provided above the edge of the outer casing.

[0035] By adopting the above technical solutions, the sealing and waterproof between the silicone sleeve 31 and the heat dissipation shell 32 are realized.

[0036] Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that: Specifically, the lamp body 3 further includes a mounting bracket 310. The mounting bracket 310 is a "U" - shaped structure. The two ends of the mounting bracket 310 are respectively connected to both sides of the heat dissipation shell 32 by screws. The end of the screw passes through the mounting bracket 310 and is threadedly connected to the heat dissipation shell 32. When assembling the whole lamp, the end of the screw passes through the driving lower cover 103 and the housing 2 in sequence and is threadedly connected to the mounting bracket 310, and then the driving board 102 is locked with the driving lower cover 103 by screws. After connecting the wire 33 with the driving board 102, the driving upper cover 101 is covered.

[0040] By adopting the above technical solution, during installation, the outer ring 4 is rotated to make the slot 42 lock onto the block 311, thus realizing the installation of the outer ring 4 and the lamp body 3. During disassembly, the outer ring 4 is simply rotated in the opposite direction to separate the slot 42 from the block 311, thus realizing the quick installation and disassembly of the outer ring 4.

[0041] Specifically, the face ring also includes an inner face ring 5, on the circumference of which are symmetrical inserts 51, and on the connecting arm are slots 41 corresponding to the inserts 51.

[0042] By adopting the above technical solution, the inner ring 5 and the outer ring 4 are assembled by inserting the insert block 51 into the slot 41, so that the inner ring 5 can be disassembled and assembled together with the outer ring 4.

[0043] Specifically, both the slot 41 and the plug 51 are arc-shaped structures, and the arc length of the plug 51 is less than the arc length of the slot 41.

[0044] By adopting the above technical solution, the inner ring 5 can rotate together with the heat sink 32.

[0052] By adopting the above technical solution, on the one hand, the building installation surface can be protected from damage, and on the other hand, the outer shell 2 can be sealed to the installation surface to prevent moisture from entering.

[0053] In summary, the power supply is achieved by the wire 33 passing through the silicone sleeve 31. The silicone sleeve 31 connects the internal cavity of the lamp body 3 with the internal cavity of the driver 1, quickly balancing the pressure difference between the inside and outside of the lamp body, avoiding the siphon effect, enhancing the waterproof effect of the entire lamp front, and preventing any impact on user safety. The two ends of the mounting bracket 310 are connected to the two sides of the heat sink 32 by screws, allowing the heat sink 32 to rotate and thus adjust the illumination direction. The outer ring 4 has two symmetrical connecting arms above it, each with a slot 42 with opposite opening directions. The mounting bracket 310 has corresponding locking blocks 311 on each slot 42.

Both the slot 41 and the insert 51 are arc-shaped structures, and the arc length of the insert 51 is less than the arc length of the slot 41, so that the inner ring 5 can rotate together with the heat sink 32. The heat sink 32 of this invention is also equipped with a DIP switch 39. The color temperature of the entire lamp can be adjusted by moving the DIP switch 39. The outer shell 2 of this invention is provided with a silicone pad 22 above the edge, which can protect the building installation surface from damage and seal the outer shell 2 with the installation surface to prevent moisture from entering.
