[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] To solve the problem of single luminous color of existing luminous beads, please refer to Figure 1-Figure 4 The utility model provides a two-color side-emitting lamp bead, which has a bracket seat 1 and a concave base 2 installed at the bottom of the bracket seat 1. Two mirror-image lamp cup grooves 3 are provided on the top of the bracket seat 1. The two lamp cup grooves 3 are each equipped with a chip component 4 for emitting two colors of light. Four pins 5 respectively connected to the two chip components 4 are installed on the concave base 2. Encapsulated fluorescent silica gel 6 for shielding and protecting the chip components 4 is installed inside the two lamp cup grooves 3.

[0023] It is worth noting that the chip assembly 4 includes two conductive pads 401 welded to the bottom of the lamp cup slot 3, one of which is provided with an LED chip 402, a die-bonding adhesive 403 is provided between the LED chip 402 and the conductive pad 401, and gold wire 404 is welded between the LED chip 402 and the two conductive pads 401. In this light-emitting lamp bead, two independent lamp cup slots 3 are provided on the bracket seat 1, and each of the two lamp cup slots 3 is equipped with an LED chip 402 emitting different colors, as well as matching conductive pads 401 and gold wire 404. In addition, of the four pins 5 provided, two are negative and two are positive, and one positive and one negative are connected to the chip assembly 4, thereby ensuring the independence of the two chip assemblies 4. Subsequently, by controlling the current of the two chip assemblies 4 separately, one of them can be selectively lit or both can be lit simultaneously, thereby achieving two different colors of light emission on a single lamp bead, thereby facilitating multiple uses of one lamp. In addition, when manufacturing the luminous lamp bead, two chip components 4 are respectively placed inside the two lamp cup grooves 3, and then phosphor powder is mixed with silica gel in a certain ratio and evenly coated on the surface of two blue LED chips 402, with different ratios on the two blue LED chips 402. Then, the LED lamp with glue applied is placed in a centrifuge for centrifugation, and the centrifuged LED lamp is placed in a high-temperature oven for baking under the optimal conditions of silica gel. After baking for a long time, the material is removed and finally the light is separated and colored. This allows the luminous lamp bead to emit two different colors of light when it is subsequently used.

[0024] When the LED chip 402 in the light-emitting lamp bead is running, it cannot completely convert the input electrical energy into light energy. Part of the electrical energy will be converted into heat energy, and the generated heat energy will accumulate in the lamp cup groove 3, causing the temperature inside the lamp cup groove 3 to rise. The high operating temperature of the LED chip 402 will accelerate the aging and degradation of the components, thereby shortening its service life. In order to effectively improve the heat dissipation effect of the LED chip 402 in the light-emitting lamp bead, such as Figure 2 and Figure 3 As shown, the bracket base 1 is provided with four gap grooves 101, one on each side of the two lamp cup grooves 3. A plurality of ventilation holes 102 interconnected with the gap grooves 101 are provided on the inner walls of both sides of the lamp cup grooves 3. A plurality of exhaust holes 103 interconnected with the gap grooves 101 are provided on the outer surface of the bracket base 1. A filter 201 extending into the interior of the gap grooves 101 is installed on the top surface of the concave base 2, and one side of the filter 201 is in contact with the inner wall of the gap groove 101 near the exhaust holes 103. A plurality of channels are formed between the ventilation holes 102, the gap grooves 101, and the plurality of exhaust holes 103, so that the heat generated by the operation of the chip assembly 4 in the lamp cup groove 3 can be discharged outward along the plurality of channels in a timely manner, thereby reducing the temperature inside the lamp cup groove 3, effectively preventing the LED chip 402 from being damaged due to being in a high temperature state for a long time, and indirectly improving the service life of the LED chip 402. In addition, the air entering the gap groove 101 along the exhaust hole 103 from the outside of the lamp bead is filtered through the filter 201, thereby effectively intercepting the fluff and dust in the air, ensuring the purity of the air entering the lamp cup groove 3, thereby effectively preventing dust from damaging the chip component 4.

[0025] Specifically, such as Figure 3 As shown, the air vents 102 are inclined from top to bottom from one end away from the gap groove 101 to the other end, and the air vents 102 are located relatively lower than the lamp cup groove 3, so that the air vents 102 directly increase the heat dissipation channel near the LED chip 402. The inclined air vents 102 are more convenient for guiding heat from the hot spot area around the LED chip 402 into the gap groove 101, effectively reducing the accumulation of heat in the lamp cup groove 3. The exhaust holes 103 are located on the upper side of the air vents 102, and the exhaust holes 103 are inclined from top to bottom from one end close to the gap groove 101 to the other end. The hot air introduced into the gap groove 101 along the air vents 102 will gradually rise, and the exhaust holes 103 set at a relatively high position are more conducive to discharging the gradually rising hot air to the outside.

[0026] like Figure 1 and Figure 4As shown, a polarity identification notch 104 is provided at one corner of the top surface of the bracket base 1, and a product identification 202 is provided in the middle of the bottom surface of the concave base 2. The polarity identification notch 104 plays an important role in facilitating polarity identification, guiding installation direction, ensuring product consistency, and assisting product management in the luminous lamp beads.
