Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 2 to 4, the combination signal lamp includes a thick-wall light guide 8 and a PCB board 9 fixedly connected to the thick-wall light guide 8, a plurality of LED lamp bead groups 11 are disposed on the PCB board 9, and each LED lamp bead group 11 includes at least two LED lamp beads capable of emitting light of different colors; be equipped with a plurality of light collimation portions 10 on the thick wall light guide 8, a plurality of light collimation portions 10 and the setting of 11 one-to-ones of multiunit LED lamp pearl group, every light collimation portion 10 all includes the notch towards the recess 18 of 11 with the corresponding LED lamp pearl group of this light collimation portion 10, and the section of recess 18 is M shape.

In this embodiment, each group of LED lamp bead groups 11 includes a first LED lamp bead capable of emitting white light and a second LED lamp bead capable of emitting amber light. First LED lamp pearl can send white light, sends the white light of different luminance through the adjustment current size to position lamp and daytime driving lamp before can forming, second LED lamp pearl can send amber light and form preceding indicator.

In this embodiment, in order to make the combination signal lamp give off light more evenly, a straight line is arranged into to multiunit LED lamp pearl group 11, and first LED lamp pearl in multiunit LED lamp pearl group 11 and the second LED lamp pearl in multiunit LED lamp pearl group 11 set up alternately.

In this embodiment, the outer walls of the two sides of each light collimation portion 10 are respectively provided with an inclined optical surface 19, and the distance between the two inclined optical surfaces 19 gradually increases along the direction away from the LED lamp bead group 11 corresponding to the light collimation portion 10. The grooves 18 and the inclined optical surfaces 19 are beneficial to collimation of light rays emitted by the LED lamp bead group 11, and the grooves 18 with M-shaped sections have the advantage of good collimation effect. Further, in order to improve the collimation effect, the groove 18 is a semicircular groove, the inclined optical surface 19 is a semicircular inclined surface, and the inclined optical surface 19 and the groove 18 are coaxially arranged.

In this embodiment, the PCB 9 is fixedly mounted on the thick-wall light guide 8 by two screws 13, two mounting holes 15 matched with the screws 13 are formed in the PCB 9, two threaded holes 14 for connecting with the screws 13 are formed in the thick-wall light guide 8, two positioning pins 16 are formed in the thick-wall light guide 8, and two positioning holes 17 respectively matched with the two positioning pins 16 are formed in the PCB 9.

In the embodiment, the thick-wall light guide 8 is provided with the light emitting surface 12, and the light emitting surface 12 is provided with patterns which can make light diffuse, so that the light irradiated from the light emitting surface 12 is more uniform, and the light irradiated from the light emitting surface 12 can meet the requirements of signal lamp regulations.

When the combined signal lamp is used, when one signal lamp is lighted, the corresponding LED lamp beads are lighted, light rays pass through the light collimation part 10 and then irradiate into the thick-wall light guide 8, after the light rays in the thick-wall light guide 8 are refracted and reflected, most of light rays can uniformly irradiate on the light emitting surface 12 of the thick-wall light guide 8. If another signal lamp needs to be lightened, according to a preset condition, the vehicle lamp controller sends a signal for extinguishing the previously lightened signal lamp and lightening the other signal lamp, so that the other LED lamp bead is lightened.
