LED lighting assembly

Abstract

This utility model relates to an LED lighting assembly, comprising: a heat sink; a sealing gasket placed on the mounting surface of the heat sink; an LED module fixed on the mounting surface of the heat sink and located within the sealing gasket; a lens module placed on the sealing gasket; and a pressure frame with multiple buckles along its outer contour. The buckles engage with the heat sink, pressing the lens module and the sealing gasket onto the mounting surface of the heat sink. The sealing gasket has an upper surface and a lower surface, with the upper surface contacting the lens module and the lower surface contacting the mounting surface of the heat sink. This design, through the engagement of the buckles with the heat sink, ensures uniform pressure on the lens module and the sealing gasket by the pressure frame, guaranteeing consistent deformation of the sealing gasket and preventing dust and other impurities from easily entering the LED lighting assembly. The increased sealing contact area of ​​the sealing gasket further improves the sealing effect of the LED lighting assembly.

Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to LED lighting components. Background Technology

[0002] Traditional LED lighting fixtures consist of a frame, a lens, an LED module, and a mounting base (heat sink). The frame and mounting base are connected by fasteners, and the lens and LED module are pressed between the frame and the mounting base. Due to inconsistent torque of the fasteners, the frame may be fixed crookedly on the mounting base, causing the lens to be fixed crookedly on the mounting base as well. This uneven force on the lens leads to lens deformation and affects the lens's light transmission.

[0003] In addition, the lens and the mounting base are connected by a sealing ring with a circular cross-section. Due to the force exerted on the lens, the deformation of the sealing ring is inconsistent. As a result, the part of the sealing ring with smaller deformation has a poorer seal with the lens and the mounting base. Dust and other impurities can enter the interior of the sealing ring through the gap, affecting the light transmittance of the device.

[0004] In summary, improving the sealing performance between the lens and the heat sink has become an urgent problem for those in the field. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to improve the sealing performance between the lens and the heat sink;

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model relates to an LED lighting assembly, comprising: a heat sink; a sealing gasket placed on the mounting surface of the heat sink; an LED module fixed on the mounting surface of the heat sink and located within the sealing gasket; a lens module placed on the sealing gasket; and a pressure frame with multiple buckles along its outer contour, the buckles engaging with the heat sink to press the lens module and the sealing gasket onto the mounting surface of the heat sink; the sealing gasket has an upper plane and a lower plane, the upper plane contacting the lens module and the lower plane contacting the mounting surface of the heat sink; the outer wall of the sealing gasket is coated with sealant, which is used to seal the gap between the sealing gasket and the mounting surface of the heat sink, as well as the gap between the sealing gasket and the lens module.

[0008] Furthermore, a pressure strip is provided in the middle of the pressure frame, the end of the pressure strip is connected to the long side of the pressure frame, and the end face of the pressure strip contacts the middle of the lens module.

[0009] Furthermore, the lens module is made of glass.

[0010] Furthermore, the lens module has an electrical appliance receiving cavity protruding from the center; a groove is provided at the pressure strip, and when the pressure strip presses the lens module, the groove matches the electrical appliance receiving cavity.

[0011] The beneficial effects of this utility model are as follows: This utility model is an LED lighting component. This solution uses a snap-fit ​​connection between the buckle and the heat sink to ensure that the pressure of the pressure frame on the lens module and the sealing gasket is uniform and consistent, thus ensuring that the deformation of the sealing gasket is consistent and that dust and other impurities are not easily allowed to enter the interior of the LED lighting component. The upper surface of the sealing gasket contacts the lens module, and the lower surface contacts the mounting surface of the heat sink. Compared with a sealing ring with a circular cross-section, the sealing contact area of ​​the sealing gasket is increased. Because the pressure of the pressure frame on the lens module and the sealing gasket is uniform and consistent, the sealing effect of the LED lighting component is further improved.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] To improve the sealing performance between the lens and the heat sink, this application discloses the following embodiments.

[0019] This embodiment is an LED lighting component; see [link / reference]. Figure 1 , Figure 1 This is an exploded view of an LED lighting assembly. From bottom to top, the components are: heat sink 1, sealing gasket 2, LED module (not shown), lens module 3, and pressure frame 4. The top surface of the heat sink 1 is the mounting surface 11. Multiple clips 41 on the outer contour of the pressure frame 4 engage with the heat sink 1, pressing the lens module 3 and sealing gasket 2 between the heat sink 1 and the pressure frame 4, forming... Figure 2 The structure of LED lighting components in the middle;

[0020] Unlike traditional technologies that use fasteners to rotate and tighten, this embodiment uses the snap-fit ​​41 and the heat sink 1 to engage, so that the pressure frame 4 applies uniform pressure to the lens module 3 and the sealing gasket 2, ensuring that the deformation of the sealing gasket 2 is consistent and that dust and other impurities are not easily allowed to enter the LED lighting components.

[0021] See Figure 1 The sealing gasket 2 has an upper surface 21 at the top and a lower surface 22 at the bottom. The upper surface 21 contacts the lens module 3, and the lower surface 22 contacts the mounting surface 11 of the heat sink 1. Compared with the sealing ring with a circular cross-section, the sealing contact area of ​​the sealing gasket 2 is increased. Since the pressure frame 4 exerts a uniform and consistent pressure on the lens module 3 and the sealing gasket 2, the sealing effect of the LED lighting component is further improved.

[0022] See Figure 3 , Figure 3 This is a cross-sectional view of an LED lighting assembly. In the figure, the lens module 3 and the sealing gasket 2 are pressed between the heat sink 1 and the pressure frame 4. The outer periphery of the sealing gasket 2 is coated with sealant 4, which contacts the heat sink 1 and the lens module 3. The sealant 5 fills the gap between the sealing gasket 2, the mounting surface 11 of the heat sink 1, and the gap between the sealing gasket 2 and the lens module 3, further improving the sealing effect.

[0023] The specific installation steps are as follows: First, fix the LED module on the mounting surface 11 of the heat sink 1, place the sealing gasket 2 on the mounting surface, then apply sealant 5 to the outer ring of the sealing gasket 2, then place the lens module 3 on the sealing gasket 2, and finally press down the pressure frame 4 until the snap-fit ​​41 engages with the heat sink 1 to complete the assembly of the LED lighting components; during this process, the sealing gasket 2 is compressed, and the sealant 5 flows and fills the gap between the sealing gasket 2, the mounting surface 11 of the heat sink 1, and the gap between the sealing gasket 2 and the lens module 3.

[0024] In this embodiment, the lens module 3 is made of glass. Compared with PC material, glass material can improve the light transmittance of LED lighting components.

[0025] See Figure 1 In this embodiment, the lens module 3 has a protruding electrical receiving cavity 31 in the middle. The electrical receiving cavity 31 is used to house the components of the LED module. Personnel can easily see the internal components through the electrical receiving cavity 31, which is unsightly; see also Figure 4 , Figure 4 A pressure strip 42 is provided in the middle, which contacts and supports the lens module 3 to ensure that the lens module 3 does not deform; in addition, a groove 43 is provided in the pressure strip 42, which matches the electrical appliance receiving cavity 31. Due to the obstruction of the pressure strip 42, the aesthetics of the LED lighting component are improved.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
