Abstract
A vehicle lamp having a switching structure for low-beam and high-beam headlights is provided. The vehicle lamp includes a heat dissipating device, an LED light source, an electromagnet, a reflector assembly, a lens unit, a light-shaping plate, a driving rod, and an intermediate plate. The LED light source and the electromagnet are disposed on the heat dissipating device, and the light-shaping plate is rotatably disposed on the electromagnet. The driving rod is disposed between the electromagnet and the light-shaping plate, and the electromagnet drives the driving rod to synchronously drive the light-shaping plate to be moved to a first position or a second position. The intermediate plate is replaceably connected between the lens unit and the heat dissipating device.
Claims7
A vehicle lamp having a switching structure for low-beam and high-beam headlights, comprising:
- a heat dissipating device;
- an LED light source disposed on the heat dissipating device;
- an electromagnet disposed on the heat dissipating device;
- a reflector assembly located above the LED light source;
- a lens unit located in front of the reflector assembly, wherein light emitted from the LED light source is capable of being reflected by the reflector assembly and being irradiated outward through the lens unit;
- a light-shaping plate being rotatably disposed between the reflector assembly and the lens unit, wherein the light-shaping plate is pivotally connected to the heat dissipating device by a rotation shaft and is able to be moved between a first position and a second position;
- a driving rod disposed between the electromagnet and the light-shaping plate;
- wherein the electromagnet is capable of driving the driving rod to synchronously drive the light-shaping plate to be moved to the first position or the second position so as to change a reflected light of the LED light source, so that the reflected light forms a low-beam or a high-beam;
- and
- an intermediate plate replaceably connected between the lens unit and the heat dissipating device, wherein a plurality of lamp seat assembly holes are formed on the intermediate plate;
- wherein the intermediate plate has a horizontal portion and two vertical portions, and the two vertical portions are respectively connected to two ends of the horizontal portion;
- wherein the horizontal portion has at least one first lamp seat assembly hole formed thereon, and each of the two vertical portions has at least one second lamp seat assembly hole formed thereon;
- and
- wherein the driving rod has a pivot portion, an active end, and a slave end, and the active end and the slave end are respectively connected to two ends of the pivot portion, wherein the pivot portion is pivotally connected to a pivot shaft of the heat dissipating device, the active end is connected to the electromagnet, and the slave end is connected to and the light-shaping plate, wherein the active end is capable of moving along a direction that is perpendicular to a light axis and the slave end is capable of moving along a front-rear direction, so as to change directions of power transmission of the electromagnet and the light-shaping plate.
