Solid light, or hard light, is a hypothetical material consisting of light in a solidified state. It has been theorized that solid light could exist. [ 1 ] [ 2 ] Some experiments claim to have created solid photonic matter or molecules by inducing strong interaction between photons.
English: Military map symbol for a friendly unit or formation. The blue frame and icon were defined in APP-6 to indicate friendly. In APP-6A, the option to use a solid "Crystal Blue" fill was introduced for friendly units. In APP-6, all units were represented by a rectangle with dimensions that varied from 1.5 by 1 to 1.7 by 1.
Hard light, an approach for computationally blending images; A type of tactile hologram in science fiction; Hardlight, a video game development studio acquired by Sega "Hardlight" (song), released in 2022 by indie rock band Spacey Jane; Solid light, a theoretical state of light that is solid via strong interactions between photons
This is a list of sources of light, the visible part of the electromagnetic spectrum.Light sources produce photons from another energy source, such as heat, chemical reactions, or conversion of mass or a different frequency of electromagnetic energy, and include light bulbs and stars like the Sun. Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that ...
A common thermal light source in history is the glowing solid particles in flames, but these also emit most of their radiation in the infrared and only a fraction in the visible spectrum. The peak of the black-body spectrum is in the deep infrared, at about 10 micrometre wavelength, for relatively cool objects like human beings.

An assortment of LED lamps commercially available as of 2010 as replacements for screw-in bulbs, including floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications. Solid-state lighting (SSL) is a type of lighting that uses semiconductor light-emitting diodes ...
Photoluminescence (abbreviated as PL) is light emission from any form of matter after the absorption of photons (electromagnetic radiation). [1] It is one of many forms of luminescence (light emission) and is initiated by photoexcitation (i.e. photons that excite electrons to a higher energy level in an atom), hence the prefix photo-. [2]
