Luminescence sheet manufactured on basis of transparent substrate and manufacturing method thereof

Abstract

The invention discloses a luminescence sheet manufactured on the basis of a transparent substrate. Raw materials of the luminescence sheet comprise the transparent substrate and a mixture composed offluorescent powder, low-melting-point glass powder and organic matter; one face of the transparent substrate is plated with an antireflection film capable of enhancing blue light transmission, and theother face of the transparent substrate is plated with a reflecting film capable of enhancing yellow light reflection; and the mixture composed of the fluorescent powder, the low-melting-point glasspowder and the organic matter is brushed onto the face, coated with the antireflection film, of the transparent substrate. The invention further provides a manufacturing method for the luminescence sheet manufactured on the basis of the transparent substrate. Compared with the prior art, the manufacturing method of the luminescence sheet is simple, in addition, the manufactured finished luminescence sheet is high in luminescence strength and compact and firm in luminescence layer and has high mechanical strength.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a light-emitting sheet manufactured based on a transparent substrate and a manufacturing method thereof. Background technique [0002] Laser lighting is to use semiconductor lasers as the core light source, use laser light mixing, color adjustment and other technologies to convert laser light sources into any form of light source, form various lighting fixtures, and then apply them to the lighting field. [0003] Restricted by the structure of commercial laser diodes, the current laser-based lighting sources mostly adopt the form of remote packaging, that is, the light-emitting sheet formed by the substrate covered with phosphor powder is fixed above the laser diode. After power-on, the light emitted by the laser diode excites the Light-emitting sheet, the light-emitting sheet emits light, and the light emitted by the light-emitting sheet under the action of laser is...

Problems solved by technology

However, the synthesis temperature of luminescent ceramics is extremely high (usually greater than 1500°C), the process is complicated, and a secondary firing process is required (pre-sintering first, then vacuum annealing), and the cost of the obtained luminescent chips is relatively high; while the temperature of luminescent glass is relatively low. (usually less than 1000°C), but the mechanical strength of the obtained product is low, and it is difficult to apply to light-emitting devices
