What is UV bulb?

UV (UV) bulb is a relatively general term to describe most types of lamps capable of producing ultraviolet light. UV light is a short wave form of electromagnetic radiation, which is generally invisible to the mere eye. It occurs naturally in sunlight and is created artificially in electrical arches and ultraviolet lamps. Common types of UV flask include fluorescent tubes, black light and gas drain lamps. UV lamps have a wide range of uses including medical and cosmetic treatments, pest control, safety verification and cure of certain adhesives.

Ultraviolet light has wavelengths between 10 and 400 nanometers, which place it at a higher frequency of ringing than in violet light, hence its name. UV light naturally occurs in sunlight and is also artificially generated by electric arches and specially designed lamps. There are several UV bulbs classes that have specific characteristics of ultraviolet radiation such as UV-A, UV-B and UV-C waveslength. The bridge in common is high -pressure mercury or fluorescent varieties, although several other types are available. The theses include xenon arch, metal-alide, mercury-xenone arch, deuterium arc and tungsten-halogen bulbs.

UV bulb usually consists of a glass envelope containing a pressure mixture of inert gases and a small amount of mercury. This glass envelope also contains an electric fiber covered with carefully formulated and applied phosphor layer. When the bulb is under voltage, the inert gases transmit the charge to the mercury, causing the reaction in the atomic structure and the production of UV radiation. The phosphor coating effectively examines this radiation to allow the emitting of certain wavelengths of the UV light depending on the coating structure. The manipulation of the composition of this phosphor layer allows very accurate control of the volume and nature of the emitted UV light.

These bulbs can be used for different procesAces that rely on exposure to various wavelengths UV. Common UV systems include medical and cosmetic treatments such as sunbeds used for sunbathing and treatment of eczema and vitiliga. Photochemotherapy used to treat psoriasis is a combined treatment including simultaneous exposure to psoral and UV-light. UV light is also a useful forensic examination tool because it reveals the presence of body fluids such as blood, sperm and saliva regardless of the surface. Shortwave UV-C light is also often used to kill bacterial, such as E. coli and giardia in drinking water by drawing microorganisms that cannot be replicated.

The

bulb of this kind is also used as an attractive insect device in zapper errors. Items printed or covered with several phosphorize materials live glow when they are exposed to UV light and are considerably used as decorative accessories. UV Light Sources are also LUSTING TO WORK IN Verification Facilities,which are able to detect otherwise invisible security features on holographic credit cards and bank notes. UV bulb emissions can also remove programming from components of a deceivable programmable reading of memory only (EPROM). Many adhesives and watering resins also cure or harden when exposed to light light sources, allowing them to use the flexibility of treatment on request.
