Vehicle lamp illuminating apparatus with ability for implementing various illuminating light patterns
A vehicle lamp illuminating apparatus with ability for implementing various illuminating light patterns is constructed by a lens, a circuit board, a plurality of light emitting diode (LED) light sources disposed on the circuit board and distributed in an array, and a reflection structure disposed between the plurality of LED light sources and the lens. The LED light sources are transversely arranged in an upper row and a lower row. The reflection structure has a plurality of reflection mirror sets each disposed in one-to-one correspondence with two LED light sources that are vertically opposite to each other. Luminance of one or more local areas of an illuminating light pattern can be adjusted, thus implementing various illuminating light patterns and meeting a self-adaptive requirement of a headlamp.
