Embodiment Construction

[0012] See Figure 1A , Figure 1A It is a structural schematic diagram of the first embodiment of the wavelength conversion device of the present invention. As shown in the figure, the wavelength conversion device of this embodiment includes a substrate 101 with a through hole 106, and two ends of the through hole 106 are respectively a light entrance 107 and a light exit 108. The wavelength conversion device also includes a wavelength conversion material 103 arranged in the through hole 106 and in close contact with the inner wall of the through hole 106. In this embodiment, the wavelength conversion material is filled inside the through hole 106. The wavelength conversion material 103 is used to receive the incident The excitation light 104 passes through the hole and emits the stimulated light. Wherein, the inner wall of the through hole 106 is reflective to the exciting light and the receiving light. The wavelength conversion device also includes a first light splitting ...

Abstract

The invention provides a wavelength conversion device and a light emitting device. The wavelength conversion device comprises a substrate with a through hole, wherein a light incoming opening and a light outgoing opening are respectively formed in two ends of the through hole. The wavelength conversion device also comprises a wavelength conversion material which is arranged in the through hole and is in close contact with the inner wall of the through hole; the wavelength conversion material is used for receiving exciting light which is incoming into the through hole and emitting excited light; and the inner wall of the through hole has a reflectivity for the exciting light and the excited light. The wavelength conversion device also comprises a first light splitting device which is arranged at one side of the light incoming opening of the through hole and covers the light incoming opening, wherein the first light splitting device is capable of transmitting the exciting light and reflecting the excited light. The wavelength conversion material is arranged in the through hole of the substrate and is in good contact with the inner wall of the substrate, so that the radiating effect is excellent; and meanwhile, the through hole of the substrate forms a light collector, and the collected light can be outgoing only through the light outgoing opening of the through hole, so that a high-brightness light source with a small optical extend is obtained.

Description

Technical field: [0001] The invention relates to the field of illumination light sources, in particular to a wavelength conversion device and a light emitting device using the wavelength conversion device. Background technique: [0002] With the development of semiconductor technology, LED light sources are replacing traditional incandescent lamps and energy-saving lamps as a new type of lighting source, which has the advantages of high efficiency, energy saving, environmental protection and long life. However, in some special application fields, such as stage lighting, car headlights, projection display and other fields, what is needed is a light source with ultra-high brightness, and it is difficult for LEDs to meet the requirements at this time. Semiconductor lasers (hereinafter referred to as LD), which belong to the same semiconductor light source as LEDs, also have the advantages of LEDs. At the same time, due to their small etendue, they are especially suitable for ...
