Abstract

[0002] Most conventional lighting devices use a metal case to improve heat dissipation, and the metal case is connected to a ground point to meet safety requirements. However, a parasitic capacitance is formed between the copper foil on the light source board and the metal case. When the switch is turned on, an AC voltage is applied to the light source (connected to the copper foil) on the light source board. When an AC voltage is applied to the parasitic capacitance, it becomes conductive, and the light source on the light source board is subjected to a certain reverse voltage. If this reverse voltage is applied to the light source for a long period of time, it will cause damage to the light source.
[0003] Several solutions have been proposed to solve the above problems: One common solution is to add a Zener diode to the lighting device circuit, but this solution increases costs and reduces light efficiency.

[0015] In one embodiment, the number of the plurality of second extension portions is greater than the number of the plurality of first extension portions.
[0016] In one embodiment, the bracket further includes a reflector cup disposed within the bracket, the light source disposed within the reflector cup, and a filler material disposed within the reflector cup. [Effects of the Invention]
[0017] Based on the above, a light emitting diode with high reverse voltage resistance according to an embodiment of the present invention may have one or more of the following advantages.
[0018] (1) In one embodiment of the present invention, a light-emitting diode includes a bracket, a positive electrode pad, a negative electrode pad, and a light source. The positive electrode pad is installed within the bracket and includes a first body and a first extension portion connected to each other. The negative electrode pad is installed within the bracket and includes a second body and two second extension portions. The two second extension portions are connected to the second body. The light source is installed within the bracket and electrically connected to the positive electrode pad and the negative electrode pad. The two second extension portions extend toward the positive electrode pad, forming an accommodating space between the two second extension portions. The first extension portion extends toward the accommodating space. Therefore, a capacitor can be formed between the first extension portion and any adjacent second extension portion, making the light source equivalent to a parallel connection of multiple capacitors and increasing the distributed capacitance of the light source. In this way, when a reverse voltage is applied to the light source, the distributed capacitance provides a buffering effect and prevents the light source from being damaged. As can be seen from the above, the special complementary pad structure design can greatly improve the reliability of the light emitting diode and extend the service life of the light emitting diode.
[0019] (2) In one embodiment of the present invention, the light emitting diode has a complementary pad structure design, which increases the distributed capacitance of the light source without using circuit components such as Zener diodes, thereby improving the reliability of the light emitting diode. This significantly reduces the cost of lighting devices using this light emitting diode and achieves high light efficiency, thereby broadening the application of light emitting diodes and better meeting the requirements of actual applications.
[0020] (3) In one embodiment of the present invention, the light emitting diode has a complementary pad structure design, which increases the distributed capacitance of the light source without requiring an independent power supply or other circuit components, thereby improving the reliability of the light emitting diode. This significantly reduces the cost of lighting devices using this light emitting diode and achieves high power efficiency, thereby broadening the application of light emitting diodes and better meeting the requirements of actual applications.
[0021] (4) In one embodiment of the present invention, the light emitting diode has a complementary pad structure design, which increases the distributed capacitance of the light source without using additional resistors, capacitors, or other circuit components, thereby improving the reliability of the light emitting diode. This significantly reduces the cost of lighting devices using this light emitting diode and achieves high light efficiency, thereby broadening the application of light emitting diodes and better meeting the requirements of actual applications.
[0022] (5) In one embodiment of the present invention, the complementary pad structure design of the LED can significantly increase the surface area of the positive and negative pads, and also increase the heat dissipation area of the LED. At the same time, the channel between the positive and negative pads can be used as a heat dissipation channel, which can significantly improve the heat dissipation performance of the LED. Therefore, the reliability of the LED can be further improved and the service life of the LED can be extended.
[0023] (6) In one embodiment of the present invention, the LED has a complementary pad structure design, which can greatly increase the distributed capacitance of each light source. Therefore, when the LED is connected to a power supply and the input voltage of the power supply is applied to the LED, the distributed capacitance can achieve an instantaneous high voltage suppression effect, preventing the LED light source from being damaged by the instantaneous high voltage. This further improves the reliability of the LED and better meets future development trends.
[0024] (7) In one embodiment of the present invention, the complementary pad structure design of the light emitting diode can not only improve the light efficiency of the lighting device, but also improve the power efficiency of the lighting device, thereby effectively improving the overall performance of the lighting device and meeting the requirements of different users.

DETAILED DESCRIPTION OF THE INVENTION
[0027] In the following embodiments, detailed features and advantages of the present invention are described, the contents of which are sufficient to enable those skilled in the art to understand the technical contents of the present invention and implement them accordingly, and the disclosure contents, claims and drawings of this specification allow those skilled in the art to easily understand the objectives and advantages of the present invention.
[0028] Hereinafter, embodiments of a light-emitting diode having high reverse voltage resistance of the present invention will be described with reference to the related drawings. However, for clarity and ease of description in the drawings, the dimensions and proportions of each component in the drawings may be exaggerated or reduced. In the following description and / or claims, when a component is described as being "connected" or "coupled" to another component, this may be directly connected or coupled to the other component, or an intervening component may be present. When a component is described as being "directly connected" or "directly coupled" to another component, this does not mean that an intervening component is present, and other terms describing the relationship between components or layers should be interpreted similarly. For ease of understanding, the same components in the following embodiments will be denoted and described with the same reference numerals.
[0029] 1 is a cross-sectional view of a structure of a light-emitting diode having high reverse voltage resistance according to one embodiment of the present invention. As shown in the figure, the light-emitting diode 1 includes a bracket 11, a positive electrode pad 12, a negative electrode pad 13, a light source 14, and a reflector cup 15.
[0030] The positive electrode pad 12 is placed in the bracket 11. The positive electrode pad 12 includes a first body 121 and a first extension 122 that are connected to each other. In one embodiment, the positive electrode pad 12 can be made of copper, aluminum, iron, or other metal materials.
[0031] The negative electrode pad 13 is installed in the bracket 11. The negative electrode pad 13 includes a second body 131 and two second extensions 132. The two second extensions 132 are connected to the second body 131, and the cross section of the negative electrode pad 13 is U-shaped. In one embodiment, the negative electrode pad 13 can be made of copper, aluminum, iron, or other metal materials.
[0032] A reflector cup 15 is mounted within the bracket 11. In one embodiment, the reflector cup 15 may be made of metal, plastic, or other similar material.
[0033] The light source 14 is mounted within the bracket 11 and is placed within a reflector cup 15. The reflector cup 15 is filled with a filler material FM (e.g., a mixture of phosphor powder and adhesive). The light source 14 is electrically connected to the positive and negative pads 12 and 13 via conductors CW. The light source 14 may be a light emitting diode die.
[0034] As can be seen from the figure, the two second extensions 132 of the negative electrode pad 13 extend toward the positive electrode pad 12, forming an accommodating space AS between the two second extensions 132. The first extension 122 extends toward the accommodating space AS. This structural design allows the positive electrode pad 12 and the negative electrode pad 13 to complement each other, forming a complementary pad structural design. Therefore, the first extension 122 is disposed between the two second extensions 132, with a gap between the first extension 122 and each of the second extensions 132. In this embodiment, a portion of the first extension 122 is located within the accommodating space AS, and the other portion of the first extension 122 is exposed to the outside of the accommodating space AS. In another embodiment, the first extension 122 may be located entirely within the accommodating space AS.
[0035] A capacitor (distributed capacitance) may be formed between the first extension 122 and any adjacent second extension 132, and this capacitance is connected in parallel with the parasitic capacitance of the light source 14 itself. In this manner, the light source 14 is equivalent to connecting multiple capacitors in parallel to increase the overall distributed capacitance of the light source 14. Therefore, when a reverse voltage is applied to the light source 14, the distributed capacitance provides a buffering effect, preventing damage to the light source 14. As can be seen from the above, the special complementary pad structure design can significantly improve the reliability of the light emitting diode 1 and extend the service life of the light emitting diode 1.
[0036] Furthermore, the above-mentioned complementary pad structure design eliminates the need for a Zener diode or an isolated power supply, and eliminates the need for additional resistors, capacitors, or other circuit components, and increases the distributed capacitance of the light source 14, thereby improving the reliability of the light emitting diode 1. This significantly reduces the cost of a lighting device using this light emitting diode 1 and achieves high light efficiency, thereby broadening the application of the light emitting diode 1 and better meeting the requirements of actual applications.
[0037] Furthermore, the positive electrode pad 12 includes a first body 121 and a first extension 122 connected to each other, and the negative electrode pad 13 includes a second body 131 and a plurality of second extensions 132. Therefore, the complementary pad structure design can significantly increase the surface area of the positive electrode pad 12 and the negative electrode pad 13, and simultaneously increase the heat dissipation area of the light-emitting diode 1. At the same time, the channel between the positive electrode pad 12 and the negative electrode pad 13 can be used as a heat dissipation channel, thereby significantly improving the heat dissipation performance of the light-emitting diode 1. This further improves the reliability of the light-emitting diode 1 and extends its service life.
[0038] Furthermore, when the light emitting diode 1 is connected to a power supply and the input voltage of the power supply is applied to the light emitting diode 1, the distributed capacitance achieves an effect of suppressing momentary high voltage, thereby preventing the light emitting diode 1 and the light source 14 from being damaged by momentary high voltage, thereby further improving the reliability of the light emitting diode 1 and making it more compatible with future development trends.
[0039] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the light-emitting diode with high reverse voltage resistance of this embodiment should still fall within the scope of protection of the present invention.
[0040] Fig. 2 is a cross-sectional view of a light-emitting diode having high reverse voltage resistance according to another embodiment of the present invention. Fig. 2 shows only the positive electrode pad 22 and the negative electrode pad 23 of the light-emitting diode, and the other configurations are the same as those of the above-described embodiment and are therefore not shown in Fig. 2.
[0041] Unlike the previous embodiment, the positive electrode pad 22 includes a first body 221 and a plurality of first extensions 222 connected to each other. The negative electrode pad 23 includes a second body 231 and a plurality of second extensions 232, which are connected to the second body 231. The number of the second extensions 232 is greater than the number of the first extensions 222. The second extensions 232 extend toward the positive electrode pad 22, and a plurality of accommodation spaces AS are formed between the second extensions 232. The first extensions 222 correspond to the accommodation spaces AS, respectively, and each first extension 222 extends toward the corresponding accommodation space AS. Therefore, each first extension 222 is located between two adjacent second extensions 232, and there is a gap between the first extension 222 and each second extension 232. In this embodiment, a portion of the first extending portion 222 is located within the accommodation space AS, and another portion of the first extending portion 222 is exposed to the outside of the accommodation space AS. In another embodiment, the first extending portion 222 may be located entirely within the accommodation space AS.
[0042] Similarly, a capacitor (distributed capacitance) is formed between each first extension 222 and the adjacent second extension 232, and this capacitor is connected in parallel with the parasitic capacitance of the light source itself. In this way, the light source is equivalent to connecting multiple capacitors in parallel to increase the overall distributed capacitance of the light source. Therefore, when a reverse voltage is applied to the light source, the distributed capacitance provides a buffering effect and prevents damage to the light source. As can be seen from the above, the special complementary pad structure design can significantly improve the reliability of the light emitting diode and extend the service life of the light emitting diode 2.
[0043] Furthermore, the complementary pad structure design further significantly increases the surface area of the positive electrode pad 22 and the negative electrode pad 23, simultaneously increasing the heat dissipation area of the LED. The channel between the positive electrode pad 22 and the negative electrode pad 23 can also be used as a heat dissipation channel, significantly improving the heat dissipation performance of the LED. This further improves the reliability of the LED and extends its service life. The complementary pad structure design further increases the surface area of the positive electrode pad 22 and the negative electrode pad 23, simultaneously increasing the heat dissipation area of the LED. The channel between the positive electrode pad 22 and the negative electrode pad 23 can also be used as a heat dissipation channel, significantly improving the heat dissipation performance of the LED. This further improves the reliability of the LED and extends its service life.
[0044] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the light-emitting diode with high reverse voltage resistance of this embodiment should still fall within the scope of protection of the present invention.
[0045] Most conventional lighting devices use a metal case to improve heat dissipation, and the metal case is connected to a ground point to meet safety requirements. However, a parasitic capacitance is formed between the copper foil on the light source board and the metal case. When the switch is turned on, an AC voltage is applied to the light source (connected to the copper foil) on the light source board. When an AC voltage is applied to the parasitic capacitance, it becomes conductive, and the light source on the light source board is subjected to a certain reverse voltage. If this reverse voltage is applied to the light source for a long period of time, it may damage the light source. Several solutions have been proposed to solve the above problem. One common solution is to add a Zener diode to the lighting device circuit, but this solution increases costs and reduces light efficiency. Another common solution is to add an independent power supply to the lighting device circuit, but this solution also increases costs and reduces power efficiency. Yet another common solution is to add a resistor (or capacitor) to the lighting device circuit and connect the resistor in parallel with the light source, but this solution also increases costs and reduces light efficiency. In contrast, according to an embodiment of the present invention, a light-emitting diode includes a bracket, a positive electrode pad, a negative electrode pad, and a light source. The positive pad is mounted within the bracket and includes a first body and a first extension, which are connected to each other. The negative pad is mounted within the bracket and includes a second body and two second extensions. The two second extensions are connected to the second body. The light source is mounted within the bracket and electrically connected to the positive pad and the negative pad. The two second extensions extend toward the positive pad, forming a receiving space between them. The first extension extends toward the receiving space. Therefore, a capacitor can be formed between the first extension and any adjacent second extension, making the light source equivalent to a parallel connection of multiple capacitors and increasing the overall distributed capacitance of the light source. In this way, when a reverse voltage is applied to the light source, the distributed capacitance provides a buffering effect, preventing damage to the light source. As can be seen from the above, the special complementary pad structure design significantly improves the reliability of the light-emitting diode and extends its service life.
[0046] According to an embodiment of the present invention, the light emitting diode has a complementary pad structure design, which can increase the distributed capacitance of the light source without using circuit components such as Zener diodes, thereby improving the reliability of the light emitting diode, thereby significantly reducing the cost of the lighting device using this light emitting diode and achieving high light efficiency, thereby broadening the application of the light emitting diode and better meeting the requirements of actual applications.

[0049] Furthermore, according to the embodiment of the present invention, the surface area of the positive and negative pads of the LED is significantly increased by designing the complementary pad structure, which also increases the heat dissipation area of the LED. At the same time, the channel between the positive and negative pads can be used as a heat dissipation channel, which significantly improves the heat dissipation performance of the LED. Therefore, the reliability of the LED can be further improved, and the service life of the LED can be extended.
[0050] Furthermore, according to the embodiment of the present invention, the LED has a complementary pad structure design, which can greatly increase the distributed capacitance of each light source.

[0051] In addition, according to the embodiment of the present invention, the complementary pad structure design of the light emitting diode can not only improve the light efficiency of the lighting device, but also improve the power efficiency of the lighting device, thereby effectively improving the overall performance of the lighting device and meeting the requirements of different users.
[0052] Furthermore, according to the embodiments of the present invention, the light emitting diode can achieve the desired effect with a simple design and low cost. Therefore, the light emitting diode realizes high practicality, makes the light emitting diode more flexible, and can meet the requirements of different applications. From the above, it can be seen that the light emitting diode with high reverse voltage resistance according to the embodiments of the present invention can indeed achieve excellent technical effects.

A portion of each first extension is located within the corresponding accommodation space. Each first extension is placed between two adjacent second extensions, and there is a gap between the first extension and either of the two adjacent second extensions. Step S34: Install the reflector cup into the bracket. The reflector cup can be made of metal, plastic, or other similar materials. Step S35: A light source is placed in the reflector cup and electrically connected to the positive and negative pads. The light source may be a light emitting diode die. Step S36: Fill the reflective cup with a filling material, which may be a mixture containing fluorescent powder and adhesive.
[0054] As mentioned above, the first extension extends toward the receiving space. Therefore, a capacitor can be formed between the first extension and any adjacent second extension, which is equivalent to connecting the light source in parallel with multiple capacitors, thereby increasing the overall distributed capacitance of the light source. Therefore, when a reverse voltage is applied to the light source, the distributed capacitance provides a buffering effect, preventing damage to the light source.
