Jiweina takes you to understand the secret of the blue sky lamp

Let's talk about why the sky is blue, mainly because there are many small particles floating in the Earth's atmosphere, causing scattering phenomenon. This scattering, known as Rayleigh scattering, is a phenomenon that occurs when light passes through particles that are much smaller than the wavelength of light. The visible light on our Earth is composed of a combination of blue and red light of 360 nanometers to 830 nanometers, so the sky we see appears blue (blue wavelength is short).

Blue sky lamp is also called blue sky lamp, clear sky lamp, as the name suggests, this is a kind of natural blue sky simulation of the lamp, originally designed and produced by an Italian brand. In fact, the current Qingzao lamp also uses this principle to make the sky blue panel, which can ensure that the light emitted by the lamp is white, and can make the panel of the lamp show the sky blue. The light waves of blue light mainly fall near 500 nanometers, so if you want to make the blue light effect of Rayleigh scattering, you need to add 5-30 nanometers in the panel to scatter the light.

At present, the Aozao lamps sold on the market are developed on the basis of 5 nanometer titanium dioxide, and the JWN-A01 independently developed by very small nano and has a number of patents is the leader of them, with 5 nanometer particle size, all high, aqueous phase monodisperse and other advantages, its dispersion liquid takes the blue phase, and can form the Tindahl effect. The pain points that nano titanium dioxide is easy to agglomerate and not easy to disperse are solved.
