Embodiment Construction

[0021] The present invention is described in detail below in conjunction with accompanying drawing:

[0022] Such as Figure 1-2 As shown, the present invention provides a wavelength conversion device 100, including a first reflective substrate 10 and a second reflective substrate 20 arranged in sequence from top to bottom, and a fluorescent layer 30 disposed in the first reflective substrate 10, so The first reflective substrate 10 is provided with a through hole 110 compatible with the fluorescent layer 30, the fluorescent layer 30 is limited in the through hole 110, and the lower surface of the fluorescent layer 30 is in contact with the second reflective layer. The upper surface of the substrate 20 is in contact. Specifically, by setting the first reflective substrate 10 and setting the through hole 110 in the first reflective substrate 10 that is compatible with the fluorescent layer 30, on the one hand, it plays the role of positioning and limiting the fluorescent layer...

Abstract

The invention discloses a wavelength conversion device, a light-emitting device and a laser illuminating lamp. The wavelength conversion device comprises a first reflecting substrate, a second reflecting substrate and a fluorescent layer arranged in the first reflecting substrate, wherein the first reflecting substrate and the second reflecting substrate are sequentially arranged from top to bottom, the first reflecting substrate is provided with a through hole matched with the fluorescent layer, the fluorescent layer is limited in the through hole, and the lower surface of the fluorescent layer is in contact with the upper surface of the second reflecting substrate. By forming the through hole matched with the fluorescent layer in the first reflecting substrate, the effect of positioning and limiting the fluorescent layer is played, the side wall of the through hole can reflect light emitted from the side face of the fluorescent layer back to the fluorescent layer, and formation of non-designated-direction stray light is avoided. The second reflecting substrate is arranged below the first reflecting substrate, the lower surface of the fluorescent layer is in contact with the upper surface of the second reflecting substrate, laser beams are prevented from being emitted from the lower portion of the fluorescent layer, meanwhile a heat conducting effect is played, and heat produced in the fluorescent layer is rapidly conducted out.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a wavelength conversion device, a light emitting device and a 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...
