Reflectors




It has been proven that almost all road accidents (regardless of whether they included motorcycles, cars, bicycles or even huge lorries) take place during the night and in conditions of poor visibility, for instance fog. Therefore, it is crucial that every vehicle used on the road ought to be fitted with a form of reflector as an additional visibility safety measure its an a virtually near certainty that there is a reflector to fit every single make and model of car and motorcycle since in most cases the reflectors for vehicles such as this aren't made specifically for specific models and makes and may very easily separately be attached or stuck on.



There are also several firms specialising in the manufacturing of plastic products that along with producing reflectors in a array of polymers (from standard ABS compounds to others for instance PPS, DMC and ULTEM which have a very high level of heat resistance) for a wide variety of vehicles (manufactured using vacuuming or moulding production processes), also offer a re-metallising service for headlight reflectors of classic and modern cars alike. Companies such as these are often approached to produce suitable reflectors for many makes of cars which have failed their M.O.T. tests.



For bikes in particular, reflectors are usually manufactured as a moulded tile of transparent plastic, having a smooth exterior surface (in order to allow light such as from an approaching car’s headlights to enter) whereas the back of the reflector takes the form of a range of angled spherical beads or micro-prisms. These reflectors use the principle of retroreflection to notify motorists to the presence of the cyclist traveling on the road. Retroreflection takes place when light is reflected back to the source with a minimum amount of light being scattered and lost in the surrounding area, making Retroreflectors the perfect materials for usage within the creation of car and bicycle reflectors.



When light strikes the back of a reflector such as this (meaning the surface housing the spherical beads and micro-prisms) it will do so at an angle that is greater than the ‘critical angle’ (the angle of incidence above which total internal reflection can take place). Total internal reflection in this case means that (due to the orientation of the interior surfaces) the light is totally reflected back out through the front of the reflector in the direction it came from and immediately alerts the other motorists to the presence of another vehicle on the road.

Reflectors

It has been confirmed that the majority of road accidents (regardless of whether they included cars, bicycles, motorcycles or maybe even huge lorries) occur at night in circumstances of poor visibility, for example fog. Therefore, it is important that any vehicle used on the road ought to be fitted with a form of reflector to act as an additional visibility preventative its an an almost near guarantee that there is a reflector to meet every model and make of car and motorcycle since in the majority of cases the reflectors for vehicles such as this aren't made especially for specific models and makes and can easily be separately be stuck on or attached.



There are also several firms specialising in the manufacturing of plastic products that along with producing reflectors in a selection of polymers (from standard ABS compounds to others such as PPS, DMC and ULTEM which may have a really high level of heat resistance) for a huge selection of vehicles (manufactured using vacuuming or moulding production processes), also provide a re-metallising service for headlight reflectors of classic and modern cars alike. Companies such as these in many cases are asked to manufacture suitable reflectors for many makes of cars that have not passed their M.O.T. tests.



For bikes in particular, reflectors are normally manufactured as a moulded tile of transparent plastic, with a smooth exterior surface (in order to allow light for example from an approaching car’s headlights to enter) whereas the back of the reflector takes the form of an array of angled spherical beads or micro-prisms. These reflectors use the principle of retroreflection to alert motorists to the presence of the cyclist on the road. Retroreflection happens when light is reflected back to the source with a minimum amount of light being scattered and lost in the surrounding area, making Retroreflectors the perfect materials for use in the creation of bicycle and car reflectors.



When light strikes the rear of a reflector such as this (meaning the surface housing the spherical beads and micro-prisms) it does so at an angle that is greater than the ‘critical angle’ (the angle of incidence above which total internal reflection can take place). Total internal reflection in this case means (due to the orientation of the interior surfaces) the light is totally reflected back out through the front of the reflector in the same direction it came from and immediately alerts the various other road users towards the existence of the other vehicle on the road.
