Description

Technical Field

[0001] The utility model relates to the technical field of light emitting diodes, in particular to high-efficiency light emitting diodes. Background Art

[0002] Light-emitting diodes are a commonly used light-emitting device that emits light by releasing energy through the recombination of electrons and holes. They are widely used in the field of lighting. Light-emitting diodes can efficiently convert electrical energy into light energy and have a wide range of uses in modern society, such as lighting, flat-panel displays, medical devices, etc. Light-emitting diodes are generally composed of five parts: a gold wire bonding part, an LED chip, a reflective cap, pins, and a circular epoxy resin lens.

[0003] In order to make the LEDs emit light of different colors, some existing LEDs generally change the color of the LEDs by changing the color of the epoxy resin lens. However, the light often consumes more energy in the process of passing through the color-changed epoxy resin, which weakens the intensity of the light emitted by the LED and reduces the electro-optical conversion efficiency of the LED. Utility Model Content

[0004] The purpose of the utility model is to provide a high-efficiency light emitting diode so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-efficiency light-emitting diode, comprising an epoxy resin lens mounted on the light-emitting diode, the outer peripheral side sleeve of the epoxy resin lens is provided with a color-changing mechanism, the color-changing mechanism includes a color-changing sleeve, a sealing member is provided between the epoxy resin lens and the inner wall of the bottom opening of the color-changing sleeve, and the color-changing sleeve and the epoxy resin lens are connected by a connecting mechanism.

[0006] Preferably, the color changing cover is composed of two parts, a hemispherical shell and a circular tube, and the hemispherical shell is arranged at the top end of the circular tube, the hemispherical shell and the circular tube are cast as one piece, the inner arc wall of the hemispherical shell is connected to the top arc surface of the epoxy resin lens, and the inner wall of the circular tube is connected to the outer peripheral wall of the epoxy resin lens.

[0007] Preferably, the sealing member comprises a soft ring, an annular groove is formed on the outer peripheral wall of the bottom of the epoxy resin lens, and the soft ring is arranged in the annular groove, and the soft ring contacts the inner wall of the annular groove and the inner wall of the bottom opening of the circular tube.

[0008] Preferably, the connecting mechanism includes a limiting ring, which is fixedly mounted on the bottom end of the epoxy resin lens, and the bottom end of the circular tube is in contact with the top side of the limiting ring, and the distance between the top side of the limiting ring and the bottom wall of the annular groove is smaller than the distance between the top side of the limiting ring and the bottom wall of the annular groove.

[0009] Preferably, two exhaust holes are arranged opposite to each other in the wall of the color-changing sleeve, and the top openings of the exhaust holes are communicated with the interior of the hemispherical shell.

[0010] Preferably, two exhaust pipes are relatively fixedly installed at the bottom end of the circular tube, and two circular holes are relatively opened on the bottom side of the limiting ring. The bottom of the exhaust pipe is inserted into the corresponding circular hole and contacts with the inner wall of the corresponding circular hole, and the cross-section of the bottom of the circular hole is T-shaped.

[0011] The utility model has at least the following beneficial effects:

[0012] 1. During the use of the improved light-emitting diode, the light emitted by the light-emitting diode changes its color through the color-changing sleeve.

DETAILED DESCRIPTION

[0023] In order to make the technical solution and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The utility model provides a technical solution: Figure 1-7 The utility model discloses a high-efficiency light-emitting diode, comprising an epoxy resin lens 1 mounted on the light-emitting diode, a color-changing mechanism 2 is sleeved on the outer peripheral side of the epoxy resin lens 1, the color-changing mechanism 2 comprises a color-changing sleeve 21, a blocking member 22 is provided between the epoxy resin lens 1 and the inner wall of the bottom opening of the color-changing sleeve 21, and the color-changing sleeve 21 and the epoxy resin lens 1 are connected via a connecting mechanism 3.

[0025] In this embodiment, when the improved light-emitting diode is produced, after the light-emitting diode is produced, the color-changing cover 21 may not be installed first, and when a production order is received, the color-changing cover 21 of the corresponding color is installed on the light-emitting diode, so that after the light-emitting diodes of different colors are produced, there is no market demand and there is a backlog of goods;

[0026] When installing the color-changing sleeve 21, the operator first inserts the epoxy resin lens 1 into the color-changing sleeve 21, and the gas in the color-changing sleeve 21 is directed to the outside of the color-changing sleeve 21 through the connecting mechanism 3, so that the epoxy resin lens 1 can be directly inserted into the color-changing sleeve 21, and at this time, the outer peripheral wall of the epoxy resin lens 1 is tightly fitted with the inner wall of the color-changing sleeve 21, and finally the operator injects the epoxy resin solution into the connecting mechanism 3, and fixes the color-changing sleeve 21 on the epoxy resin lens 1 through the bonding of the epoxy resin;

[0027] When the improved light emitting diode is used, the light emitted by the light emitting diode needs to pass through the color changing sleeve 21 before being emitted to the outside, thereby changing the color of the light emitted by the light emitting diode through the color changing sleeve 21;

[0028] It should be noted that the above-mentioned color-changing cover 21 is an epoxy resin cover of different colors.

[0029] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, the color changing cover 21 is composed of two parts, a hemispherical shell 211 and a circular tube 212, and the hemispherical shell 211 is arranged at the top of the circular tube 212, and the hemispherical shell 211 and the circular tube 212 are integrally cast, and the inner arc wall of the hemispherical shell 211 is connected with the top arc surface of the epoxy resin lens 1, and the inner wall of the circular tube 212 is in contact with the outer peripheral wall of the epoxy resin lens 1;

[0030] In this embodiment, the color-changing sleeve 21 composed of a hemispherical shell 211 and a circular tube 212 allows the outer wall of the epoxy resin lens 1 to fit tightly with the inner wall of the color-changing sleeve 21, thereby preventing a large gap from being generated between the epoxy resin lens 1 and the inner wall of the color-changing sleeve 21, which would affect the passage of light inside the epoxy resin lens 1 and the color-changing sleeve 21.

[0031] In a further preferred embodiment of the present invention, Figure 2 As shown, the blocking member 22 includes a soft ring 222. An annular groove 221 is formed on the outer peripheral wall of the bottom of the epoxy resin lens 1, and the soft ring 222 is disposed in the annular groove 221. The soft ring 222 contacts the inner wall of the annular groove 221 and the inner wall of the bottom opening of the circular tube 212.

[0032] In the present embodiment, after the epoxy resin lens 1 is inserted into the color changing sleeve 21, due to the mutual interference between the soft ring and the inner wall of the annular groove 221 and the inner wall of the color changing sleeve 21, the soft ring undergoes adaptive deformation, so that the soft sleeve fits tightly with the inner wall of the annular groove 221 and the inner wall of the color changing sleeve 21, thereby blocking the gap between the epoxy resin lens 1 and the inner wall of the color changing sleeve 21, preventing harmful gases from entering the color changing sleeve 21 to corrode the epoxy resin lens 1, causing the epoxy resin lens 1 to change color and be damaged.

[0033] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, the connection mechanism 3 includes a limiting ring 31, which is fixedly sleeved on the bottom end of the epoxy resin lens 1, and the bottom end of the circular tube 212 is connected to the top side of the limiting ring 31, and the distance between the top side of the limiting ring 31 and the inner bottom wall of the annular groove 221 is smaller than the distance between the top side of the limiting ring 31 and the inner bottom wall of the annular groove 221;

[0034] In this embodiment, when installing the soft ring 222, first, the soft ring 222 is sleeved on the outer peripheral side of the epoxy resin lens 1 by the hemispherical end of the epoxy resin lens 1, and then the soft ring 222 is pushed to adjust the position of the soft ring 222 on the outer peripheral side of the epoxy resin lens 1 by rotating the soft ring 222, and finally, the soft ring 222 is pushed to the opening of the annular groove 221, and then the soft ring 222 is pushed into the annular groove 221, and the soft ring 222 is mutually engaged with the limiting ring 31 and the inner wall of the annular groove 221. The soft ring 222 is prevented from slipping out of the annular groove 221 due to the contact between the annular groove 221 and the inner wall of the limiting ring 31, thereby affecting the assembly of the color changing sleeve 21 and the epoxy resin lens 1.

[0035] In a further preferred embodiment of the present invention, Figure 3-5 As shown, two exhaust holes 32 are provided in the wall of the color changing cover 21, and the top openings of the exhaust holes 32 are connected to the interior of the hemispherical shell 211;

[0036] In the present embodiment, when the epoxy resin lens 1 is inserted into the color changing sleeve 21, the gas in the color changing sleeve 21 is discharged to the outside of the color changing sleeve 21 through the circular hole 34 and the exhaust pipe 33, so as to prevent the air in the color changing sleeve 21 from affecting the insertion of the epoxy resin lens 1 into the color changing sleeve 21, thereby making the outer wall of the epoxy resin lens 1 fit tightly with the inner wall of the color changing sleeve 21.

[0037] In a further preferred embodiment of the present invention, Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, two exhaust pipes 33 are relatively fixedly installed at the bottom end of the circular tube 22, and two circular holes 34 are relatively opened on the bottom side of the limiting ring 31. The bottom of the exhaust pipe 33 is inserted into the corresponding circular hole 34 and contacts the inner wall of the corresponding circular hole 34. The cross-section of the bottom of the circular hole 34 is T-shaped.

[0038] In this embodiment, after the epoxy resin lens 1 is inserted into the color changing sleeve 21, the sealing ring 222 fits the inner wall of the color changing sleeve 21, which can block the gap between the epoxy resin lens 1 and the inner wall of the color changing sleeve 21, thereby preventing harmful gases from entering the color changing sleeve 21 to corrode the epoxy resin lens 1, causing the epoxy resin lens 1 to change color and be damaged;

[0039] After the epoxy resin solution solidifies, the top of the solidified epoxy resin solution is arc-shaped and the bottom of the solidified epoxy resin solution is T-shaped, so that the position between the color changing sleeve 21 and the epoxy resin lens 1 is locked through the mutual interference between the top of the solidified epoxy resin solution and the inner wall of the top of the exhaust hole 32 and the mutual interference between the solidified epoxy resin solution and the inner wall of the circular hole 34, and the connection between the color changing sleeve 21 and the epoxy resin lens 1 is relatively stable.

[0040] Working principle: In the production process of the improved light-emitting diode, after the production of the light-emitting diode is completed, the color-changing cover 21 may not be installed first. When the production order is received, the color-changing cover 21 of the corresponding color is installed on the light-emitting diode, thereby preventing the light-emitting diodes of different colors from being overstocked when there is no market demand after they are produced;

[0041] When connecting the above-mentioned color-changing sleeve 21 with the light-emitting diode, the operator first puts the soft ring 222 from the hemispherical end of the epoxy resin lens 1 on the outer peripheral side of the epoxy resin lens 1, then pushes the soft ring 222 to adjust the position of the soft ring 222 on the outer peripheral side of the epoxy resin lens 1 by rotating the soft ring 222, and finally pushes the soft ring 222 to the opening of the annular groove 221, and then pushes the soft ring 222 into the annular groove 221, and the soft ring 222 is mutually conflicted with the limiting ring 31 and the inner wall of the annular groove 221, so that the soft ring 222 shrinks and deforms, thereby inserting the soft ring 222 into the annular groove 221. At this time, due to the mutual conflict between the annular groove 221 and the inner wall of the limiting ring 31, the soft ring 222 is stably located in the annular groove 221;

[0042] After the soft ring 222 is installed, the operator inserts the epoxy resin lens 1 into the color changing sleeve 21, and the gas in the color changing sleeve 21 is discharged to the outside of the color changing sleeve 21 through the circular hole 34 and the exhaust pipe 33, so as to prevent the air in the color changing sleeve 21 from affecting the insertion of the epoxy resin lens 1 into the color changing sleeve 21, so that the outer wall of the epoxy resin lens 1 is closely fitted with the inner wall of the color changing sleeve 21;

[0043] It should be noted that after the epoxy resin lens 1 is inserted into the color changing sleeve 21, the sealing ring 222 fits the inner wall of the color changing sleeve 21, which can block the gap between the epoxy resin lens 1 and the inner wall of the color changing sleeve 21, thereby preventing harmful gases from entering the color changing sleeve 21 to corrode the epoxy resin lens 1, causing the epoxy resin lens 1 to change color and be damaged;

[0044] Then the operator turns the color-changing sleeve 21 and the epoxy resin lens 1 upside down, and injects the epoxy resin solution into the exhaust groove from the position of the circular hole 34 until the epoxy resin solution fills the exhaust hole 32 and the circular hole 34. After the epoxy resin solidifies, the limiting ring 31, the color-changing sleeve 21 and the epoxy resin lens 1 are connected together by the adhesive force of the epoxy resin, and the connection between the light-emitting diode and the color-changing sleeve is completed;

[0045] When the improved light emitting diode is used, the light emitted by the light emitting diode needs to pass through the color changing sleeve 21 before being emitted to the outside, thereby changing the color of the light emitted by the light emitting diode through the color changing sleeve 21;

[0046] When the transparency of the color-changing sleeve 21 decreases due to oxidation, the operator can scrape out the solidified epoxy resin in the circular hole 34 with a drill bit, thereby releasing the connection between the limit ring 31 and the color-changing sleeve 21. Then, the operator can cut off the sleeve wall of the color-changing sleeve 21 with pointed scissors, thereby peeling the color-changing sleeve 21 off the epoxy resin lens 1. Finally, according to the above, a new color-changing sleeve 21 can be installed on the outer peripheral side of the epoxy resin lens 1, and the replacement of the color-changing sleeve 21 is completed.

[0047] It should be noted that after the connection between the above-mentioned limit ring 31 and the color changing sleeve 21 is disconnected, the color changing sleeve 21 and the epoxy resin lens 1 are only connected by a very small amount of solidified epoxy resin, and the connection strength between the color changing sleeve 21 and the epoxy resin lens 1 is relatively low. During the process of peeling off the color changing sleeve 21, the connection between the solidified epoxy resin and the epoxy resin lens 1 can be disconnected by tilting the solidified epoxy resin, and finally the solidified epoxy resin remaining on the epoxy resin lens 1 can be ground off by grinding.

[0048] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
