[0002] Lamp beads can be used in the application and design of various lighting solutions such as flexible light strips, building models, running shoe light design, clothing design, travel bag design, etc.

[0003] The existing light-emitting diodes that achieve dual color temperatures are two light-emitting chips placed in parallel in a bracket with two independent grooves, and fluorescent glues of different color temperatures are respectively dotted into the two grooves to achieve a product that can emit two different colors or color temperatures on the same lamp bead. The size of the existing dual color temperature products is relatively large, with the minimum size being 3.5X2.8X0.8mm. The size and thickness of such products limit the design and application of such products in miniaturization and thinness of terminal applications. Utility Model Content

[0004] In order to solve the problems that the prior art cannot adapt to the usage requirements of different models and has poor usage safety, the utility model provides a micro light emitting diode that can achieve dual-color full color, and a first LED chip and a second LED chip are arranged in the inner cavity of a mounting plate. Since the first LED chip and the second LED chip are connected in parallel, the two LED chips can emit light simultaneously or separately to achieve different color combinations to produce a full-color effect, and the first LED chip and the second LED chip are energized through a gold wire and a second connecting wire, and a variety of different installation methods are achieved through series connection. After the installation is completed, the temperature of the inner cavity of the mounting plate can be monitored in real time through a temperature sensor to prevent the temperature of the inner cavity of the mounting plate from being too high, affecting the safety of the use of the first LED chip and the second LED chip, and ensuring that the first LED chip and the second LED chip operate within a safe temperature range. When the temperature sensor detects a temperature abnormality, it sends a signal to a warning light connected to the connecting plate through the first connecting line, and the warning light immediately lights up to remind the user to pay attention. Pay attention to temperature abnormalities to prevent the LED chip from overheating and being damaged. Since the mounting plate and the base are fixedly connected by a limit block, one end of the limit block is rotatably connected to the top of the base through a first rotating rod, and the other end is fixedly installed on the top of the mounting plate by a first bolt, ensuring the stability and positioning accuracy of the mounting plate on the base, and facilitating the disassembly of the mounting plate to replace the first LED chip and the second LED chip, or to maintain the interior of the mounting plate. Since the inner cavity of the mounting plate is coated with fluorescent glue configured with high-stability fluorescent powders of different color temperatures, when the first LED chip is connected by a gold wire, since the two ends of the gold wire are connected to the positive and negative electrodes, the currently connected first LED chip can be illuminated and a monochromatic light can be generated; when the second LED chip is connected by a gold wire, another monochromatic light can be generated. When the first LED chip and the second LED chip are powered on and lit at the same time, they will react with the fluorescent glue configured with high-stability fluorescent powders of different color temperatures coated on the inner cavity of the mounting plate, thereby generating a variety of tones and achieving a two-color full-color display effect.

[0005] To achieve the above purpose, the specific technical solution is as follows:

However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0021] Example 1: Figure 1-4 As shown, the utility model aims to provide a micro light-emitting diode that can achieve dual-color full color, so as to solve the problems in the prior art that it cannot adapt to the use requirements of different models and has poor safety of use. According to the above functions, the whole device includes a base 1, and the base 1 is provided with a mounting plate 2. The mounting plate 2 is made of a copper-plated silver material with high thermal conductivity and high reflectivity with a heat sink. At the same time, the mounting plate 2 can be filled with corresponding fluorescent glue or transparent silica gel of different component concentrations according to the color temperature or color to be achieved, so as to adapt to the lighting requirements of various colors. The inner cavity of the mounting plate 2 is provided with a first LED chip 4 and a second LED chip 5. The first LED chip 4 and the second LED chip 5 are connected in parallel. This parallel configuration allows the two LED chips to work independently, and can emit light simultaneously or separately to achieve different color combinations to produce a full-color effect. The bottom of the first LED chip 4 and the second LED chip 5 is provided with a connecting component, and the bottom of the connecting component is provided with a monitoring component for detecting the temperature of the inner cavity of the mounting plate 2. The mounting plate 2 and the base 1 are fixedly connected by a limit block 3;

[0022] Specifically, the light-emitting diode of the device is reduced in size to 2.2X2.2X1.0mm. If it is applied to a flexible light strip, the smaller lamp bead size can shorten the distance between the lamp beads and make the arrangement of the lamp beads denser, thereby obtaining a light strip product with no light spots and high light efficiency.

[0023] Example 2: Figure 1-4As shown, the monitoring component includes a temperature sensor 11 fixedly installed in the inner cavity of the base 1, and a partition plate 14 is arranged on the top of the temperature sensor 11. The partition plate 14 is fixedly sleeved on the bottom inner cavity of the mounting plate 2, and a plurality of through holes are opened on the partition plate 14, so as to facilitate the flow of the temperature of the inner cavity of the mounting plate 2 to the inner cavity of the base 1, thereby realizing the circulation of temperature and facilitating the cooling and heat dissipation of the inner cavity of the mounting plate 2.

The connecting plate 7 and the temperature sensor 11 are electrically connected through a first connecting line 12. The warning light 8 on the connecting plate 7 will light up to a corresponding degree according to the changes in the temperature of the inner cavity of the installation plate 2, thereby playing a role of reminder and warning.

[0025] like Figure 3 and Figure 4 As shown, the monitoring component includes a circuit board 15 fixedly mounted on the bottom of the inner cavity of the mounting plate 2, both ends of the circuit board 15 are fixedly connected with gold wires 17 through positioning blocks 18, and the top of the circuit board 15 is electrically connected to the first LED chip 4 and the second LED chip 5 through a second connecting wire 16. The circuit board 15 can be energized through the gold wire 17, and the second connecting wire 16 transmits power to the first LED chip 4 and the second LED chip 5 respectively, thereby realizing the separate energization of the first LED chip 4 and the second LED chip 5 or the simultaneous energization of the first LED chip 4 and the second LED chip 5.

[0026] like Figure 3 As shown, one end of the limit block 3 is rotatably connected to the top of the base 1 through the first rotating rod 13, and the other end of the limit block 3 is fixedly installed on the top of the mounting plate 2 through the first bolt 9. The limit block 3 can be used to connect and fix the mounting plate 2, and it is convenient to disassemble the first LED chip 4 and the second LED chip 5 for replacement or maintenance. The end of the limit block 3 that contacts the mounting plate 2 has a protruding part, thereby improving the limiting and fixing effect of the mounting plate 2.

[0027] like Figure 1 and Figure 2 As shown, a positive wire hole 6 is provided on one side of the mounting plate 2, and a negative wire hole 10 is provided on the other side of the mounting plate 2. The positive and negative wire holes can facilitate the installation personnel to install and distinguish the lines, ensure the correctness of the installation connection, and enable the first LED chip 4 and the second LED chip 5 to be powered on smoothly.

[0028] Working principle of this device:

[0029] When the device is needed, firstly, the first LED chip 4 and the second LED chip 5 are arranged in the inner cavity of the mounting plate 2. Since the first LED chip 4 and the second LED chip 5 are connected in parallel, the two LED chips can emit light simultaneously or separately to achieve different color combinations to produce a full-color effect. The first LED chip 4 and the second LED chip 5 are powered on by the gold wire 17 and the second connecting wire 16, and a variety of different installation methods are achieved by connecting in series. After the installation is completed, the temperature of the inner cavity of the mounting plate 2 can be monitored in real time by the temperature sensor 11 to prevent the temperature of the inner cavity of the mounting plate 2 from being too high, affecting the safety of the use of the first LED chip 4 and the second LED chip 5, and ensuring that the first LED chip 4 and the second LED chip 5 operate within a safe temperature range. When the temperature sensor 11 detects a temperature abnormality, it sends a signal to the warning light 8 connected to the connecting plate 7 through the first connecting wire 12, and the warning light 8 lights up immediately to remind the user to pay attention to the temperature abnormality to prevent the LED chip from being damaged by overheating. 2 is fixedly connected to the base 1 through a limit block 3, one end of the limit block 3 is rotatably connected to the top of the base 1 through a first rotating rod 13, and the other end is fixedly installed on the top of the mounting plate 2 through a first bolt 9, ensuring the stability and positioning accuracy of the mounting plate 2 on the base 1, and facilitating the disassembly and replacement of the first LED chip 4 and the second LED chip 5 of the mounting plate 2, or the maintenance of the interior of the mounting plate 2. Since the inner cavity of the mounting plate 2 is coated with a fluorescent glue configured with high-stability fluorescent powders of different color temperatures, when the first LED chip 4 is connected through the gold wire 17, since the two ends of the gold wire 17 are connected to the positive and negative electrodes, the currently connected first LED chip 4 can emit light and generate a monochromatic light; when the second LED chip 5 is connected through the gold wire 17, another monochromatic light can be generated. When the first LED chip 4 and the second LED chip 5 are powered on and lit at the same time, they will react with the fluorescent glue configured with high-stability fluorescent powders of different color temperatures coated in the inner cavity of the mounting plate 2, thereby generating a variety of tones and achieving a two-color full-color display effect.
