Problems solved by technology

However, the current quantum dot lighting scheme relies on short-wave blue light to excite red and green quantum dots, which cannot avoid the harm of short-wave blue light to human eyes.
Therefore, it is difficult for existing lighting devices to reduce blue light hazards while ensuring lighting quality

Abstract

The invention discloses a quantum dot lighting device. The quantum dot lighting device comprises a lighting device substrate, at least one ultraviolet excitation wide spectrum lamp bead and at least one long-wavelength blue light lamp bead. The ultraviolet excitation wide spectrum lamp beads and the long wavelength blue light lamp beads are arranged on the lighting device substrate in a matrix mode. The ultraviolet excitation wide spectrum lamp bead comprises an ultraviolet light chip and a packaging layer, the packaging layer at least covers the light emitting surface of the ultraviolet light chip; the packaging layer comprises a packaging base material, and red and orange wavelength conversion particles, yellow and green wavelength conversion particles and diffusion particles which are mixed in the packaging base material; wherein the red-orange light wavelength conversion particles and the yellow-green light wavelength conversion particles are made of quantum dot materials. According to the embodiment of the invention, the harm of blue light can be reduced while the illumination quality is ensured.

Description

technical field [0001] The present invention relates to the technical field of lighting, in particular to a quantum dot lighting device. Background technique [0002] White LEDs have been widely used in people's lives. At present, the use of blue LEDs combined with down-conversion fluorescent materials to achieve white light solutions with tunable spectrum has been applied to many consumer products, such as backlights for liquid crystal display panels and LED lighting bulbs. With the improvement of market demand and technological innovation, LED white light source has changed from the initial pursuit of high efficiency and high brightness to the pursuit of controllable light and higher color quality. However, the current commercial display solutions mostly use short-wave blue LED + phosphors, and it is difficult to achieve high-quality (full spectrum, high CRI) lighting. Therefore, quantum dot materials have begun to be paid attention and researched. The emission spectrum...
