Description

Technical Field

[0001] This utility model relates to the field of light-emitting diode module technology, and in particular to a light-emitting diode module with an installation module. Background Technology

[0002] In the structural design of ring-shaped LED lights, the connection stability between the LED light-emitting module and the ring substrate is the core factor ensuring the normal power supply and luminous performance of the lamp. Currently, most ring-shaped LED lights use a traditional interlocking mounting structure, where the pins or connection terminals of the LED light-emitting module are directly embedded into pre-set mounting slots or soldering holes in the ring substrate, and then connected with thermally conductive adhesive. While this mounting method meets basic electrical connection requirements in the initial assembly stage, during long-term use, factors such as changes in ambient temperature, LED self-heating, and material characteristics can cause gaps to appear at the interlocking position between the LED light-emitting module and the ring substrate, leading to poor electrical contact and becoming a key defect restricting the lifespan and reliability of ring-shaped LED lights. LED light-emitting modules continuously generate heat during operation, especially in high-power ring-shaped LED lights, where the operating temperature of the LED chip can reach 60-80℃, and even exceed 100℃ under some conditions. In existing technologies, LED light-emitting modules mostly use plastic encapsulation shells, while the annular substrates are mainly made of aluminum or fiberglass substrates. The two types of materials have significantly different coefficients of thermal expansion: the thermal expansion coefficient of the plastic encapsulation shell differs greatly from that of the aluminum or fiberglass substrates. During long-term temperature cycling, the thermal deformation of the plastic encapsulation shell is much greater than that of the annular substrate, leading to stress accumulation at the originally tightly fitted connection. When the stress exceeds the material's tolerance limit, gaps gradually appear and widen. A noticeable gap can be observed at the joint between the LED light-emitting module and the annular substrate in LED lights; the gap width is typically between 0.1 and 0.3 mm, and it gradually widens with prolonged use.

[0016] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0017] The illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0018] LED light-emitting modules mostly use plastic encapsulation shells, while annular substrates are mainly made of aluminum substrates or fiberglass substrates. The thermal expansion coefficients of the two types of materials are significantly different: the thermal expansion coefficient of the plastic encapsulation shell is much different from that of the aluminum substrate or fiberglass substrate. During long-term temperature cycling, the thermal deformation of the plastic encapsulation shell is much greater than that of the annular substrate, which leads to stress accumulation in the originally tightly fitted connection parts. When the stress exceeds the material's tolerance limit, the fitting gap gradually appears and continues to expand. A noticeable gap is observed at the junction of the LED light-emitting module and the annular substrate in LED lights. The gap width is typically between 0.1 and 0.3 mm, and it tends to widen gradually with prolonged use. To address this, a light-emitting diode module with a mounting module is proposed, comprising: an annular substrate 10, with a mounting groove 11 provided in the circumferential direction of the annular substrate 10; a terminal electrode 50 disposed on the annular substrate 10; an LED light-emitting module 20 mounted in the mounting groove 11; and a terminal pin 21 disposed on the LED light-emitting module 20, the terminal pin 21 being coupled to the terminal electrode 50; a flexible washer 30 covering the LED light-emitting module 20 and abutting against the groove wall of the mounting groove 11; and a fixing part 40 disposed on the LED light-emitting module 20 and forming a detachable fixed connection with the annular substrate 10.

[0019] In one embodiment, see Figure 5 and Figure 6The flexible gasket 30 is made of thermally conductive and insulating elastic rubber. When the flexible gasket 30 covers the LED light-emitting module 20, it can quickly conduct heat to the LED light-emitting module 20, thereby achieving rapid cooling of the LED light-emitting module 20 and avoiding performance degradation caused by excessive temperature. The flexible gasket 30 covers the LED light-emitting module 20 and abuts against the wall of the mounting groove 11. It can absorb the stress caused by the difference in thermal expansion coefficients between the LED light-emitting module 20 and the annular substrate 10 through its own elastic deformation, eliminating the formation of gaps between the two and ensuring a long-term tight fit, thus avoiding the hidden dangers caused by gaps from the root. Furthermore, the connection pin 21 and the connection electrode 50, together with the stable positioning of the LED light-emitting module 20 by the flexible gasket 30, can maintain a constant contact pressure between the two, significantly reducing electrical contact resistance, completely solving the problem of poor electrical contact, and avoiding performance failures such as brightness decay and flickering of the lamp.

[0020] In one embodiment, see Figure 6 and Figure 8 To ensure reliable electrical contact between the wiring pin 21 and the wiring electrode 50, an elastic sheet 51 is provided on the wiring electrode 50, and the wiring pin 21 of the LED light-emitting module 20 is in electrical contact with the elastic sheet 51.

[0021] In the above embodiments, the elastic sheet on the terminal electrode 50 can form a continuous and stable clamping force on the terminal pin 21 of the LED light-emitting module through its own elastic deformation. Even if the LED light-emitting module 20 undergoes a slight displacement due to temperature changes, the elastic sheet 51 can still maintain close contact with the terminal pin 21, avoiding contact pressure fluctuations and further ensuring the stability of the electrical connection. The elastic properties of the elastic sheet 51 can absorb the slight stress between the terminal pin 21 and the terminal electrode 50 caused by assembly errors or long-term use, preventing deformation of the terminal pin 21 and wear of the terminal electrode 50 caused by rigid contact, extending the service life of both, and reducing the risk of electrical contact failure caused by damage to the contact components.

[0022] In one embodiment, to connect the LED light-emitting module 20 to the annular substrate 10, the mounting groove 11 is opened along the inner circumferential direction of the annular substrate 10, and an overlapping groove 12 is also opened on the annular surface of the annular substrate 10. The overlapping groove 12 is located at the edge of the mounting groove 11, and a mounting hole 121 is opened at the bottom of the overlapping groove 12. The fixing part 40 passes through the LED light-emitting module 20 and is connected to the mounting hole 121.

[0023] In one embodiment, see Figure 5 and Figure 6The LED light-emitting module 20 is generally rectangular. A connecting plate 22 is provided on the edge of the outer shell of the LED light-emitting module 20. When the LED light-emitting module 20 is inserted into the mounting groove 11, the connecting plate 22 is inserted into the connecting groove 12. A through hole 221 is provided on the connecting plate 22. (See reference...) Figure 3 The enlarged view shows that the fixing part 40 passes through the through hole 221 and is inserted into the mounting hole 121.

[0024] Specifically, see Figure 7 To achieve a tight fit between the flexible washer 30 and the outer wall of the LED light-emitting module 20, a step 23 is provided on the bottom surface of the outer shell of the LED light-emitting module 20. The flexible washer 30 is in the shape of a rectangular ring and is arranged around the platform of the step 23.

[0025] The aforementioned flexible washer 30 is positioned around the platform of the step 23, allowing the end face of the flexible washer 30 to engage with the groove wall and bottom surface of the mounting groove 11, thereby ensuring a reliable connection between the LED light-emitting module 20 and the annular substrate 10.

[0026] In one embodiment, to ensure a sealed and elastic connection between the overlapping plate 22 and the overlapping groove 12, a connecting sealing tube 222 is provided on the overlapping plate 22. The connecting sealing tube 222 is arranged concentrically with the through hole 221 and is inserted into the mounting hole 121.

[0027] In one embodiment, see Figure 1 and Figure 6 The outer wall of the sealing tube 222 is provided with a through deformation part, and the fixing part 40 is a pin that passes through the inner wall of the sealing tube 222.

[0028] The aforementioned fixing part 40 is a pin with a large end and a small body. When the sealing tube 222 is inserted into the mounting hole 121, the fixing part 40 passes through the sealing tube 222, causing the sealing tube 222 to expand. This, in turn, causes the through deformation part of the sealing tube 222 to expand, thereby making the outer wall of the sealing tube 222 tightly connected with the wall of the mounting hole 121.

[0029] In one embodiment, the sealing tube 222 may also be made of thermally conductive and insulating elastic rubber.

[0030] In one embodiment, the wiring pin 21 is vertically arranged on the bottom surface of the housing of the LED light-emitting module 20.

[0031] Specifically, see Figure 8The enlarged view shows that the annular substrate 10 has an annular groove 13 on its annular surface away from the mounting groove 11. The terminal piece 50 is fitted into the annular groove 13. The bottom of the annular groove 13 has an insertion hole 131. (See reference...) Figure 4 The enlarged view shows that the wiring pin 21 passes through the plug hole 131 and is connected to the wiring electrode 50.

[0032] In the above embodiment, a receiving area is provided at the bottom of the annular groove 13 where the opening of the plug hole 131 is located. This receiving area is used to receive the elastic sheet 51. When the wiring pin 21 passes through the plug hole 131, its end can abut against the elastic sheet 51.

[0033] In one embodiment, a sealing ring 211 is fitted on the wiring pin 21, and the sealing ring 211 is engaged with the insertion hole 131.
