[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods, so that the implementation process of how the application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0020] Since the current single-cup LED cannot meet the requirements of dual-color or multi-color use, and the cost is high and the practicality is insufficient, please refer to Figures 1-4 The present embodiment provides a two-color common anode side-emitting lamp bead, which can adjust three colors for a single lamp bead, meeting the use requirements of two-color or multi-color luminescence, and the lamp bead has a low cost and greatly improved practicality. The lamp bead includes a lamp holder 1, and two limit plates 6 for limited sliding are fixedly connected to the top of the lamp holder 1, and a dimming component 2 for shielding and scattering light is slidably connected to the top of the lamp holder 1. The dimming component 2 includes two recessed transparent scattering lenses 201 for scattering light, and an opaque shading plate 202 for shielding light is fixedly connected between the two scattering lenses 201. The side end of the shading plate 202 is fixedly connected to a toggle rod 203 for toggling the scattering lens 201 and the shading plate 202 so that the dimming component 2 can slide in a straight line.

[0021] Before implementation, the lamp holder needs to be processed. The processing process is to use a double-cup bracket to fix the chip to realize the function of dual-color side-emitting, and then use fluorescent powder and silica gel mixed in a certain proportion to stir for a period of time. The recommended ratio is between 1:1 and 1:3, and the recommended time is controlled at about 20 minutes. The utility model uses a ratio of 1:2 fluorescent powder and silica gel, and the stirring time is controlled at 20 minutes. After stirring evenly, the mixture is coated on the surface of the blue light chip, that is, the upper surface of the fluorescent groove 401 in the groove. The color of the fluorescent powder can be selected by matching. For example, if red, blue and purple colors of light are required, the fluorescent powder can be determined as one blue and one red, and the blue light and red light are mixed into purple light to emit the third color of light. At the same time, the mixture should cover the top of the chip 403, and then the LED lamp holder with glue is placed in a centrifuge for centrifugation.

[0022] The centrifuged LED lamp beads are placed in a high-temperature oven and baked according to the optimal conditions of the silica gel. The optimal conditions are that the baking temperature is between 80 and 200 degrees, and the baking time is controlled within 1 to 24 hours. In this utility model, it is only necessary to bake at a temperature of 120 degrees for 2 hours, and then take it out after long baking. During use, the light-emitting color is mainly adjusted by the toggle lever 203. For example, three colors of red, blue, and purple are selected. If you want to emit only red light, you can adjust the toggle lever 203 to slide and make the light-shielding plate 202 completely cover the top surface of the blue fluorescent groove. When emitting light, due to the shielding effect of the light-shielding plate 202, the LED will only emit red light. At the same time, the position of the red light source uses the scattering lens 201 to further scatter the light, which can expand the illumination area and make the light softer. If you want to switch to blue light, just shield the red light. If you want to adjust to purple light, adjust the light-shielding plate 202 to the middle position so that the two color lights are emitted at the same time. The scattering lens 201 scatters and mixes the two lights at the same time. The scattered red light and blue light can be mixed better and softer, and the purple light is made more natural.

[0023] In an alternative embodiment, as Figure 2 and Figure 3 shown, the inner side of the lamp holder 1 is provided with a groove with an inclined surface, so that the uncured epoxy resin can better cover the groove. A light-emitting component 4 for common anode of two colors is fixedly connected in the groove. The light-emitting component 4 includes a fluorescent groove 401 for emitting two colors of light. A plurality of conductive solder pads 402 convenient for conductive welding are fixedly connected to the bottom end of the groove. Among them, the top end of the conductive solder pad 402 near the middle position of the groove is fixedly connected with a chip 403 for emitting light. A conductive pin 404 for connection is fixedly connected to the side end of the conductive solder pad 402, and the conductive pin 404 penetrates through the side end of the lamp holder 1.

[0024] It should be noted that the conductive solder pad can play a conductive function after welding. A mixture of fluorescent powder and silica gel is placed on the top of the fluorescent groove 401. The chip 403 emits light through moving electrons and holes. The conductive pin is used for connecting the LED lamp bead to the external circuit.

[0025] In an alternative embodiment, as Figure 1 shown, heat dissipation components 3 for heat dissipation and limiting are fixedly connected to the two side walls of the lamp holder 1. A product identification 5 is fixedly connected to the bottom surface of the lamp holder 1. A polarity notch 101 for identifying the polarity is provided at the corner position of the top surface of the lamp holder 1. The heat dissipation component 3 includes a plurality of heat dissipation fins 301 fixedly connected to the outer side wall of the lamp holder 1 for increasing heat dissipation. A limiting inclined surface 302 for limiting is provided at the bottom end of each heat dissipation fin 301.

[0026] It should be noted that during the use process, since the smooth bottom surface of the LED lamp bead is not easy to be fixed inside the groove during the fixing process, the heat dissipation component 3 can enable the LED lamp bead to be smoothly limited inside the groove by the action of the inclined surface and gravity during the installation process. Through the heat dissipation function of the heat dissipation component 3, the present utility model can assist in the heat dissipation of the lamp holder and avoid circuit problems caused by overheating of the lamp holder.

[0027] When fixing the lamp holder, the inclined surface can be used to better limit and fix the lamp holder 1 inside the groove, avoiding the difficulty of fixing the lamp holder inside the groove during installation. During the subsequent movement after fixation, the interaction between the inclined surface and the groove can be utilized to prevent the position from shifting due to movement or jolting, which may affect normal use, thus improving the safety and heat dissipation of the LED lamp bead. The polarity notch 101 can be used to identify the polarity of the LED lamp bead, preventing the operator from wasting time due to the inability to quickly identify it.

[0028] The heat dissipation component 3 can quickly dissipate the heat of the LED lamp bead through the side heat sink 301, reducing the temperature of the LED lamp bead and preventing the LED lamp bead from being in danger due to overheating. At the same time, the inclined surface and gravity of the limiting inclined surface 302 enable the lamp bead to be quickly limited inside the groove for fixation, thereby greatly improving the use efficiency of the LED lamp bead.

[0029] In an alternative embodiment, as Figure 1 shown, the inner side of the limiting plate 6 is slidably connected to the top surface of the dimming component 2. It should be noted that the limiting plate 6 can assist in the limiting and sliding of the light shielding plate 202 and the scattering lens 201 during the operation of the dimming component 2.

For the same or similar parts among the embodiments, reference can be made to each other. For the above embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and for the relevant parts, reference can be made to the partial description of the method embodiments.
