Scattering device and lamp

Abstract

The embodiment of the invention provides a scattering device. The scattering device comprises a scattering board; the scattering board comprises a light entering surface for receiving light rays and a light emitting surface for emitting the light rays; the scattering device further comprises a transparent medium and first type scattering particles distributed inside the transparent medium; and the first type scattering particles can enable light received through the light entering surface of the scattering board to form rayleigh scattering, and rayleigh scattering light rays formed through the first type scattering particles can be emitted through the light emitting surface of the scattering board. The embodiment of the invention further provides a lamp. The lamp comprises the scattering device and a light source; and light emitted by the light source is emitted after being scattered through the scattering board. After the light rays are emitted through the scattering device provided by the embodiment of the invention, the nature feeling of color temperature of sunlight and a blue canopy of a sunny sky can be imitated, the nature feeling of the light rays is improved, and the comfort degree is improved.

Description

technical field The embodiments of the present invention relate to the field of optical technology, and in particular to a scattering device and a lamp. Background technique Because there is no atmosphere in space, when people do not face the sun or stars, the light of the sun or stars cannot enter the human eye through scattering or refraction, so the sky is black. From the perspective of the earth, due to the scattering of light by atmospheric particles, it can be seen that on a sunny day, the scattered natural light makes the sky appear bright blue or light blue. On cloudy days, diffused natural light makes the sky appear pure white, while the sky at the horizon in the morning and evening appears orange. In modern buildings, there is often a lack of natural light or insufficient lighting due to space constraints. In order to improve this situation, artificial lighting lamps are installed in most buildings. However, the light emitted by these lamps is always consistent i...

Problems solved by technology

In modern buildings, there is often a lack of natural light or insufficient lighting due to space constraints. In order to improve this situation, artificial lighting lamps are installed in most buildings. However, the light emitted by these lamps is always consistent in terms of brightness and color temperature. Fixed, it cannot change with seasons or time of day like natural light, nor can it change with weather conditions. needs

In addition, when people work in such an environment with constant brightness and color temperature for a long time, it will cause visual fatigue and even psychological discomfort.

The lamps and lanterns of the prior art cannot make the user visually experience the visual eff
