Laser light source and lamp

Abstract

The invention discloses a laser light source. The laser light source comprises a laser emission source, a light gathering component, a fluorescence sheet and a planoconvex lens, wherein the laser emission source is used for emitting laser; laser emitted by the laser emission source is gathered by the light gathering component, is subsequently irradiated into the fluorescence sheet and is capable of exciting the fluorescence sheet and enabling the fluorescence sheet to emit excited laser; the planoconvex lens is located between the light gathering component and a fluorescence sheet light path;the fluorescence sheet is adhered to the plane of the planoconvex lens; the convex surface of the planoconvex lens is plated with a light filtering film capable of transmitting the laser and reflecting the excited laser; the surface shape of the convex surface of the planoconvex lens can enable the fluorescence sheet to face to the excited laser emitted by the planoconvex lens; the excited laser is irradiated into the convex surface of the planoconvex lens, is subsequently reflected and can return to light-emitting light spots excited to emit light of the fluorescence sheet. The invention alsodiscloses a lamp comprising the laser light source; part of laser emitted backwards in the excited laser emitted by the fluorescence sheet can be reflected back to the light-emitting light spots by the convex surface of the planoconvex lens, so that the light can be concentrated in the light-emitting light spots and is subsequently emitted out, the energy can be concentrated as far as possible, and then the luminescence brightness can be effectively improved.

Description

technical field [0001] The invention relates to the lighting field, in particular to a laser light source and a lamp using the laser light source. Background technique [0002] Lamps belong to the traditional field, and there are many kinds of lamps and lanterns. After the appearance of LEDs, lamps and lanterns using LEDs as light sources also emerged in an endless stream. However, with the improvement of people's living standards, there is an increasing demand for lighting, especially decorative lighting, but this demand has not been fully met yet. Contents of the invention [0003] The present invention proposes a laser light source, which includes a laser emitting source for emitting laser light; a light concentrating component and a fluorescent sheet. Emitting the received light; a plano-convex lens located between the condensing assembly and the optical path of the fluorescent sheet, the fluorescent sheet is bonded to the plane of the plano-convex lens, and the ...
