Light source module, illuminating lamp and application thereof

Abstract

The invention discloses a light source module, an illuminating lamp and an application thereof. The light source module comprises a light source unit, a wavelength conversion unit and a reflecting unit. The light source unit comprises a laser source and an LED light source. The reflecting unit refers to a curved mirror, and a light outlet is formed in one side of the reflecting unit. The wavelength conversion unit is located at the focus position of the curved mirror. Laser beams emitted from the laser source are projected onto the upper surface of the wavelength conversion unit and further give out fluorescent light, and the fluorescent light is reflected by the reflecting unit and then forms an illuminating light beam to be emitted out of the light outlet of the reflecting unit. The light source module further comprises a collimation and beam expanding unit which is arranged at the outer side of the light outlet of the reflecting unit along a light path. The LED light source is located on the periphery of the collimation and beam expanding unit. According to the light source module, the illuminating lamp and the application thereof, due to the fact that the LED light source is arranged on the periphery of the collimation and beam expanding unit, when vehicles are under the conditions of close-range illuminating or turning and the like, the LED light source is turned on so that the illuminating range can be changed or increased; and meanwhile, shielding of the illuminating light beam emergent from the light outlet of the reflecting unit is well avoided, and the illuminating effect and adaptability are greatly improved.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a light source module, a lighting lamp and applications thereof. 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, due to the limitation of the brightness of the current LED light source, there is usually the problem that the central illumination is obviously not enough. In applications such as marine searchlights, stage lighting, car headlights, projection displays, etc. that require ultra-high brightness and long-distance lighting, LED The light source is difficult to meet the requirements. [0003] The laser light source has the advantages of concentrated ener...
