Abstract

The invention discloses a self-adaptive laser illuminating lamp. The self-adaptive laser illuminating lamp comprises a laser source unit, a wavelength conversion unit and a reflection unit, and further comprises a first adjusting unit and a control unit, wherein the first adjusting unit is connected to the laser source unit, and the control unit is connected to the first adjusting unit; a laser beam emitted by the laser source unit is projected to the upper surface of the wavelength conversion unit; the control unit controls the first adjusting unit to adjust the position of the laser source unit so as to change the projection position of the laser beam on the upper surface of the wavelength conversion unit; the upper surface of the wavelength conversion unit is located at the focal point of the reflection unit; the wavelength conversion comprises a plurality of fluorescent layers which are closely arranged; and a diffuse reflection layer is arranged on the outer periphery of the side surface of each fluorescent layer. According to the self-adaptive laser illuminating lamp, the whole vehicle lamp is not required to be adjusted, the energy consumption is reduced, the control precision is high, the stability is good, the self-adaptive laser illuminating lamp can be applied to complex roads and driving environments and is wide in applicability, and the requirements of actual application can be practically met.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an adaptive laser lighting lamp. Background technique [0002] With the development of semiconductor technology, LED (Light Emitting Diode, light-emitting diode) light source has the advantages of high efficiency, energy saving, environmental protection, low cost and long life, and is gradually replacing traditional incandescent lamps and energy-saving lamps, becoming a general lighting light source. [0003] In the existing LED car headlights, the LED light source is located at the focal point of the reflective bowl of the car light. The light beam emitted by the LED light source is collected by the reflective bowl of the car light and distributed by the rear optical system (including baffles, lenses, etc.). Project the required far and near light field distribution. This type can obtain the light distribution of the low beam of the car headlights that meets the demand. Howev...
