bicycle lighting

bicycle lighting is illumination attached to bicycles whose purpose above all is, along with reflectors, to improve the visibility of the bicycle and its rider to other road users under circumstances of poor ambient illumination. a secondary purpose is to illuminate reflective materials such as cat's eyes and traffic signs.a third purpose may be to illuminate the roadway so that the rider can .

liter of light

liter of light is an open source design for a low-cost light tube that refracts solar light to provide daytime interior lighting for dwellings with thin roofs. daylighting is cheaper than using indoor electric lights during the day. the device is simple: a transparent two-liter bottle is filled with water plus a little bleach to inhibit algal growth and fitted into a hole in a roof.

led strip light

pavement light

pavement lights, vault lights, floor lights, or sidewalk prisms are flat-topped walk-on skylights, usually set into pavement or floors to let sunlight into the space below. they often use anidolic lighting prisms to throw the light sideways under the building. they were developed in the 19th century, but declined in popularity with the advent of cheap electric lighting. older cities and smaller centers around the world have or have had pavement lights. most such lights are approximately a centur

tactile paving

tactile paving also called tenji blocks, truncated domes, detectable warnings, tactile ground surface indicators, tactile walking surface indicators, or detectable warning surfaces is a system of textured ground surface indicator found on footpaths, stairs and train station platforms to assist pedestrians who are visually impaired.

led strip light

'neon' or 'flex' led tape refers to led tape constructed in such a way to emulate neon lights. the led tape is embedded on the side of a silicone filled, plastic c-channel; the silicone both diffuses the light from the led tape and directs it out to one side, 90 degrees to the direction the smd leds face.

plasticity physics

in physics and materials science, plasticity, also known as plastic deformation, is the ability of a solid material to undergo permanent deformation, a non-reversible change of shape in response to applied forces. for example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur within the material itself. in engineering, the transition from elastic behavior to plastic behavior is known as yielding. plastic deformation is observed in most m

lighting for the elderly

designing lighting for the elderly requires special consideration and care from architects and lighting designers. as people age, they experience neurodegeneration in the retina and in the suprachiasmatic nucleus scn . less light reaches the back of the eyes because the pupils decrease in size as you age, the lens inside your eye becomes thicker, and the lens scatters more light, causing .

disco ball

photopolymer

a photopolymer or light-activated resin is a polymer that changes its properties when exposed to light, often in the ultraviolet or visible region of the electromagnetic spectrum. these changes are often manifested structurally, for example hardening of the material occurs as a result of cross-linking when exposed to light. an example is shown below depicting a mixture of monomers, oligomers .

lightbulb socket

a lightbulb socket, light socket, lamp socket or lampholder is a device which mechanically supports and provides electrical connections for a compatible electric lamp.sockets allow lamps to be safely and conveniently replaced re-lamping . there are many different standards for lampholders, including early de facto standards and later standards created by various standards bodies.
