Description
Technical field
The present invention relates to a kind of ultraviolet ray (Ultraviolet; UV) slaking lamp; Especially UV cold-cathode fluorescence lamp (Cold Cathode Florescent Lamp; CCFL), utilize UV phosphor that UV excites UV wavelength, the nail that is coated on finger or toe and the specific nail lacquer on the animal pets nail are solidified with conversion light.
Background technology
The professional skill field of nail art is introduced the whole world widely, and grows up along with irradiation and the development of nail lacquer composition and improvement, to concoct different new technologies.Generally, nail art is meant cosmetic or the decoration to the nail of finger or toe.Traditional nail art can use resin or the colloidal state artificial composition of polymerization at room temperature to form artificial nails.Can in the quite short time, form or aggregate into the more advanced nail lacquer of artificial nails, can use the UV radiation to strengthen this slaking or aggregation processing.
There has been incandescent UV lamp can be fit to the different lamps in Different Industries and the commercial application.Traditional incandescent UV lamp major part comprises coating layer or wavelength filter layer/film, to reach the UV irradiation of required purpose, comprises the UVA, UVB and the UVC that launch different spectral regions.Yet, in the nail art field, use this UV incandescent lamp, have binomial doubt at least and be and use this UV incandescent lamp relevant in this field.One of them is; Under these UV incandescent lamps or bulb, can let people's skin be exposed to UV light for a long time and cause the danger of cutaneum carcinoma; Because with reference to protection to skin; The UV incandescent lamp is three kinds of UV light of emission usually, and these are UVA (wavelength 400nm to 315nm), UVB (wavelength 315nm to 280nm), and UVC (wavelength 280nm to 100nm).It is important, known in these three kinds of light, the UVC wavelength of 280nm to 100nm, or with energy, be tool nocuity and tool highest energy in three kinds.Another major defect is that the use life time of UV incandescent lamp is quite short, and needs often maintenance.General UV incandescent lamp has the use life time of 3000 hours (or about 4 months), and if when adopting light fixture or the machine system of this UV lamp to comprise meticulous assembly and/or electric connector and/or circuit, then be not the most desirable in the time must changing.
The technical development in illumination recently also let electricity-saving lamp (Compact Florescent Lamp, CFL) and light-emitting diode (LED) illumination in different commerce and commercial Application, become possibility.Known CFL lamp has suitable energy in the general lighting field, can produce the sufficient light of wide-angle; Yet; The fluorescent tube that is adopted in it at present or the spiral-shaped and size of lamp bag; Get the mercury plasma that is contained in it and use and produce or when reaching the required even illumination of the enough lumen output of tool, can be easy to the generation problem if the time have any UV excite compound to be introduced in it to be excited with response in operation.Be prone to speech, be found to CFL at present or standard shape and structure be can't be only in it injection UV excite compound in response to or produce enough or required even UV radiation with being contained in mercury ion steam or the plasma in it together.In addition, the LED that is made up of semi-conducting material also can be in order to produce the UV radiation.The wavelength of LED emission light is the function that p-n connects the band gap of face institute materials used.Known LED is becoming power conversions to have very high efficient in the light; However, at present can emission wavelength UV LED or LED in UV spectrum still to be developed to and have in visible wavelength and the general suitable efficient of LED.In fact find, because the restriction of existing UV LED, be transmitted in UV radiation in the UV spectral region and also be not considered to be far away and in visible light, have the efficient identical with other known LED.In addition; UV LED is subject to the lighting angle of its point-source of light just as the existing LED of major part; And need a plurality of modules be used for the field of illumination, with the white heat of equal illumination output and given area or CFL light ratio, can increase unwanted integral material and settle cost.Produce the required more high-power of enough or required UV radiation by existing UV LED, can increase the too many operating temperature of UV LED or connect surface temperature, for existing UV radiation and the most modern application can cause unsuitable or unpractiaca solution.
And for the nail art field, the outward appearance of nail lacquer is quite important for artificial nails after known curing time and the slaking.That is, in order in the short curing time, to accomplish maturation process, nail lacquer polymerization at the appointed time or curing as stated so nail lacquer must respond the UV radiation.Commercial nail lacquer can be the fluent material of high viscosity, comprise can be under normal room temperature be main monomer with the methacrylic acid in back polymerization or curing sometime.And with prior resin type nail lacquer by comparison, the artificial nails of these colloidal state can cause lighter smell or skin irritatin, and also can have the better property grasped.Yet the slaking artificial nails of colloidal state nail still can flavescence, and thereby can't satisfy client's aesthetic requirement.Another factor is that the slaking of typical nail lacquer or curing generally need the very long processing time, and can involve or not involve the photopolymerization starting agent.Known, this photopolymerization starting agent is an important component for certain nail lacquer, but in order to response UV light and mat UV radiation with effective slaking.
Since on address to the nail art field; Therefore best mode is the UV radiation that will consider the UV light source simultaneously and want mat UV light source with the form of the nail lacquer that carries out slaking; So that the UV radial burner has energy-efficient at least; UV light can reduce the adverse effect of human body, the UVC wavelength between the 80nm to 100nm especially, but and can painstakingly obtain to comprise the result of nail lacquer outward appearance of the artificial nails of this UV aging system.That is; Need a kind ofly can overcome and comprise the above-mentioned UV lamp of putting forward the known technology shortcoming of incandescent lamp, CFL lamp and LED lamp; And the UV radiation that can produce safe, reliable and effective rate, but especially in the field of nail art and to the nail lacquer of slaking under this UV radiation.In addition, a kind of UV lamp need be provided, to make things convenient for once safety and the effective nail protection of creating nail art and a plurality of finger or the toe of tool high-reliability.
