Description

Technical Field

[0001] This utility model belongs to the technical field of LED brackets, specifically a high-efficiency LED bracket. Background Technology

[0002] In recent years, with the widespread application of light-emitting diode (LED) technology in lighting, display, and decoration, LED packaging technology has developed rapidly. As a core component of LED devices, the LED bracket directly affects chip fixation, electrical connection, optical performance, and heat dissipation, making it a key factor determining LED performance and reliability. Traditional LED brackets typically use a metal substrate combined with a plastic cup, achieving conductivity through electroplated pins, and using adhesive to protect the chip and optimize light output, as disclosed in patent document "CN218568868U" regarding "An LED bracket and LED packaging structure." However, in multi-color LED applications, such as holographic LEDs, this technical solution struggles to achieve dynamic color adjustment with a single chip or packaging method, and light interference between multiple color light sources affects color purity and uniformity. Furthermore, to achieve high color rendering or specific color temperatures, such as white light, phosphors are often added to the encapsulating colloid; however, uneven phosphor distribution can lead to spotting or color deviation problems.

[0003] Therefore, there is an urgent need for a new type of LED bracket design that can achieve multi-color light output, high color rendering, and long-term reliability to meet the requirements. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency LED bracket to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency LED bracket includes several pins, with a cup body injection molded onto each pin. The cavity of the cup body is divided into a first functional area and a second functional area by a partition wall. A blue light chip and a green light chip are disposed in the first functional area, and the blue light chip and the green light chip are covered by an encapsulating colloid mixed with phosphor. A single blue light chip is disposed in the second functional area, and the single blue light chip is covered by a transparent colloid.

[0007] In a further technical solution, the plurality of pins includes six pins, wherein the first functional area corresponds to the first pin, the second pin, the third pin and the fourth pin, the second functional area corresponds to the fourth pin, the fifth pin and the sixth pin, the fourth pin passes through the first functional area and the second functional area, and the surface of the pin is plated with a silver layer, the thickness of the silver layer being 0.04mm-0.06mm.

[0008] In a further technical solution, the blue light chip, the green light chip, and the single blue light chip are all bound to the fourth pin. The positive and negative terminals of the blue light chip are electrically connected to the first and second pins, respectively. The positive and negative terminals of the green light chip are electrically connected to the first and third pins, respectively. The positive and negative terminals of the single blue light chip are electrically connected to the fifth and sixth pins, respectively.

[0009] In a further technical solution, the height of the partition wall is lower than the rim of the cup.

[0010] In a further technical solution, the cup body is provided with identification point one and identification point two.

[0011] In a further technical solution, the inner wall of the cup is provided with a reflective coating.

[0012] The beneficial effects of this utility model are:

[0013] The partition design of the inner sidewall of the cup in this utility model separates the blue light chip, green light chip and phosphor located in the first functional area and the single blue light chip located in the second functional area. This significantly reduces the mutual interference between the excitation light of the blue light chip, green light chip and phosphor in the first functional area and the single blue light chip in the second functional area, ensuring the purity of light color and improving high luminous efficiency.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Traditional LED brackets typically combine a metal substrate with a plastic cup body, achieving conductivity through electroplated pins, and utilizing encapsulation colloids to protect the chip and optimize light output. However, in multi-color LED applications, existing technologies struggle to achieve dynamic color control with a single chip or encapsulation structure. Furthermore, light interference easily occurs between multi-color light sources, affecting the purity and uniformity of the light color. To achieve high color rendering or specific color temperatures, such as white light, phosphors need to be added to the encapsulation colloid. However, uneven phosphor distribution or insufficient matching with the bracket structure can easily lead to light spot or color deviation problems.

[0021] Therefore, please refer to Figure 1-3 This embodiment discloses a high-efficiency LED bracket, including several pins 1, with a cup 2 injection molded on each pin 1. The cavity of the cup 2 is divided into a first functional area 4 and a second functional area 5 by a partition wall 3. A blue light chip 6 and a green light chip 7 are disposed in the first functional area 4, and the blue light chip 6 and the green light chip 7 are covered by an encapsulating colloid mixed with phosphor. A single blue light chip 8 is disposed in the second functional area 5, and the single blue light chip 8 is covered by a transparent colloid. In this embodiment, the phosphor can be yellow phosphor. It is worth noting that after the first functional area 4 is covered by the encapsulating colloid mixed with phosphor, it can be covered a second time by a transparent colloid.

[0022] Specifically, the partition wall 3 on the inner wall of the cup body 2 separates the blue light chip 6, green light chip 7 and phosphor located in the first functional area 4 from the single blue light chip 8 located in the second functional area 5. This significantly reduces the mutual interference between the excitation light of the blue light chip 6, green light chip 7, and phosphor in the first functional area 4 and the single blue light chip 8 in the second functional area 5, ensuring the purity of light color and improving high luminous efficiency. The blue light chip 6, green light chip 7 and yellow phosphor in the first functional area 4 combine to generate high color rendering white light through efficient wavelength conversion, further optimizing the uniformity of light output and improving the electro-optical conversion efficiency. Moreover, the partition wall 3 avoids cross-interference of light colors, significantly improving the purity and consistency of light color, which is suitable for the dynamic light color adjustment needs of iridescent LEDs.

[0023] In this embodiment, the multiple pins 1 include six pins, wherein the first functional area 4 corresponds to the first pin 11, the second pin 12, the third pin 13 and the fourth pin 14, the second functional area 5 corresponds to the fourth pin 14, the fifth pin 15 and the sixth pin 16, the fourth pin 14 passes through the first functional area 4 and the second functional area 5, and the surface of the pin is plated with a silver layer with a thickness of 0.75μm-3μm. Preferably, in this embodiment, the thickness of the silver layer is 2μm. Further, the blue light chip 6, the green light chip 7 and the single blue light chip 8 are all bound to the fourth pin 14. The positive and negative terminals of the blue light chip 6 are electrically connected to the first pin 11 and the second pin 12, respectively. The positive and negative terminals of the green light chip 7 are electrically connected to the first pin 11 and the third pin 13, respectively. The positive and negative terminals of the single blue light chip 8 are electrically connected to the fifth pin 15 and the sixth pin 16, respectively.

[0024] Specifically, through optimized pin layout and electrical connection design, the convenience of light and color control and the stability of electrical performance are significantly improved. The first functional area 4 corresponds to pins 11, 12, 13, and 14; the second functional area 5 corresponds to pins 14, 15, and 16. Pin 14 passes through the first functional area 4 and the second functional area 5. The pin surface is plated with a silver layer with a thickness of 0.75μm-3μm. Blue LED chip 6, green LED chip 7, and a single blue LED chip 8 are all bonded to pin 14. The positive and negative terminals of blue LED chip 6 are electrically connected to pins 11 and 12, respectively. The positive and negative terminals of the green light chip 7 are electrically connected to the first pin 11 and the third pin 13, respectively, and the positive and negative terminals of the single blue light chip 8 are electrically connected to the fifth pin 15 and the sixth pin 16, respectively. Through the reasonable allocation of the six pins and the shared design of the fourth pin 14, the blue light chip 6, the green light chip 7, and the single blue light chip 8 are independently electrically connected, supporting precise current control and light color adjustment. The blue and green light chips 7 in the first functional area 4 and the single blue light chip 8 in the second functional area 5 can be driven separately, which facilitates the realization of multi-color dynamic light mixing effects such as RGBW, and meets the flexible control requirements of colorful LEDs in smart lighting and displays.

[0025] In this embodiment, the height of the partition wall 3 is lower than the mouth of the cup body 2. During manufacturing, the operator can separate the encapsulating colloid and the transparent colloid in the first functional area 4. There are two implementation methods. The first implementation method is to fill the second functional area 5 with transparent colloid, at which time the height of the transparent colloid is lower than the partition wall 3, and fill the first functional area 4 with encapsulating colloid so that it can be separated by the partition wall 3. Finally, the first functional area 4 and the second functional area 5 are filled with transparent colloid a second time, at which time the height of the transparent colloid exceeds the partition wall 3. The second implementation method is to first fill the first functional area 4 with encapsulating colloid with a height not exceeding the partition wall 3. After the encapsulating colloid is filled, the first functional area 4 and the second functional area 5 are directly filled with transparent colloid a second time.

[0026] In this embodiment, the cup body 2 is provided with identification point 18 and identification point 19 to improve identification efficiency and convenience; in this embodiment, the inner wall of the cup body 2 is provided with a reflective coating 20 to improve the confusion between the blue light chip 6, the green light chip 7 and the yellow phosphor.
