Description

Technical Field

[0001] This utility model relates to the field of LED vehicle lighting technology, specifically to an LED vehicle lighting system with two types of LED beads to enable switching between low beam and high beam. Background Technology

[0002] According to standards, all vehicle headlights must have both low beam and high beam functionality. Currently, to achieve the switching between high and low beams, an LED light panel is installed inside the LED headlight, with at least one LED bulb on the panel. A switching device for high and low beams is also included. When using low beams, the light-blocking plate of the switching device rises to block part of the light, while when using high beams, the light-blocking plate lowers, allowing the light emitted by the LED bulb to be emitted without any obstruction. Although this structure can achieve the switching between high and low beams, it is complex and costly. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an LED vehicle light with multiple LED beads, which adopts a simple structure to achieve switching between high and low beams and has low cost.

[0021] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-2 As shown, this utility model embodiment provides an LED vehicle light with multiple LED beads, including: a body 1, a substrate 2 disposed on the body; and further including: a first LED bead 3 and n second LED beads 4 disposed on the substrate, and a lens 5 disposed on the body and located in front of the first LED bead and the second LED beads; the n second LED beads are arranged in a row and the first LED bead is located on one side of the row of second LED beads; n is a positive integer; the "row of second LED beads" here refers to the n second LED beads arranged in a row. That is, the first LED bead and the second LED beads are packaged on the same substrate and share a lens to reduce the area of ​​the substrate; the significance is that if the first LED bead and the lens are packaged separately and the n second LED beads are also packaged separately with another lens, then the two types of LED beads are first packaged separately with their respective lenses and then fixed on the substrate, which occupies a larger area.

[0023] In this embodiment, specifically, n is a multiple of three. Three adjacent second LED beads 4 form a group, and three second LED beads in the same group are connected in series. Clearly, this means that when grouping n second LED beads 4, adjacent three second LED beads are first grouped together. Currently, the power supply voltage for LED vehicle lights is generally 9V, and the voltage of a single LED bead is 3V. Therefore, connecting three adjacent second LED beads in series results in a voltage of 9V, which is convenient for compatibility with the current vehicle power supply voltage. After the three second LED beads in the same group are connected in series, adjacent groups of second LED beads 4 are connected in parallel.

[0024] like Figure 3 As shown, n=6, meaning this embodiment uses six second LED beads 4 as an example for detailed explanation. Specifically, the six second LED beads 4 are divided into two groups; the two groups of second LED beads 4 are connected in parallel and share a common positive electrode, while the negative electrodes of the two groups of second LED beads are separate, as shown. Figure 4 As shown. Obviously, although this embodiment uses the setting of six second LED beads 4 as an example for detailed description, for those skilled in the art, manufacturers can customize different numbers of second LED beads 4 according to customer needs, such as setting one set of second LED beads 4 or setting three or more sets of second LED beads 4. Apart from changing the brightness, the other technical effects are the same, that is, the function and effect of high and low beam switching of this application are the same.

[0025] like Figure 4As shown, the first LED bead 3 has a positive terminal and a negative terminal, and the pads electrically connected to the positive and negative terminals are fixed on the substrate 2; the first LED bead 3 is elliptical or circular; the second LED bead 4 is square; as shown... Figure 2 As shown, this embodiment takes setting an elliptical first LED bead 3 as an example, and the effect is the same as setting a circular first LED bead.

[0026] During processing, the two negative electrodes of the two sets of second LED beads 4 connected in parallel are electrically connected to the same solder pad on the substrate 2, that is, the two negative electrodes share one solder pad, which helps to simplify the structure and reduce the welding process.

[0027] In this embodiment, the substrate 2 is a ceramic substrate; the spacing between the second LED bead 4 and the first LED bead 3 in a row is 0.36cm. The small spacing between the two types of LED beads ensures that when both are lit simultaneously to achieve the high beam function, the emitted light pattern has no shadows. Figure 3 As shown.

[0028] like Figures 1-2 As shown, for mounting the substrate 2, the main body 1 is provided with a mounting base 101, and a longitudinal mounting groove is provided in the mounting base. A mounting plate 102 is provided in the longitudinal mounting groove; the substrate 2 is fixed on the mounting plate and n second LED beads 4 arranged in a row are located above the first LED beads 3; when it is necessary to switch to high beam, the first LED beads 3 are turned on, and the light emitted is refracted by the lens and located above the light emitted by the second LED beads, thereby realizing the high beam function, as shown. Figure 5 As shown.

[0029] In order to install the lens 5, a mounting ring 6 is also provided on the main body 1 in front of the mounting base 101, and the lens 5 is fixed on the mounting ring.

[0030] In summary, this design incorporates several second LED beads 4 arranged in a row. During operation, these second LED beads 4 emit a rectangular beam pattern and function as low beams. Below these second LED beads 4, an elliptical or circular first LED bead 3 is positioned. Both types of LED beads share a single lens 5, but are controlled independently. When switching to high beam, the first LED bead 3 is activated. The emitted light, refracted by the lens 5, is positioned above the light emitted by the second LED beads 4, thus achieving the high beam function. Compared to existing technologies, this structure eliminates the need for a switching device for high and low beams, simplifying the LED headlight structure and saving costs.
