Black Light LED industry specific applications dental nsk very promising. According
to PIDA (PIDA), engaged in the black light LED chip manufacturers,
including major Japanese manufacturers Nichia, the nitride semiconductor
(NS). Although
NS has been a supplier of chips, grain, encapsulation, application, it
is basically handled 355nm ~ 400nm low-power products. U.S. manufacturers semiconductor light-emitting diodes, high power and low power products trading. Silicon Base, the company's subsidiaries, mainly to provide packaging services. Taiwanese
manufacturers including Formosa Epitaxy (3061), Thai Valley (3339), New
Century (3383), Canton Ga (8199) and other companies. They are mainly engaged in the UV wavelength (315 to 400 nm) within the scope of development, emphasizing product at 360nm.
Albeit limited UV LED luminous efficiency and cost price factors. It is difficult in the mainstream white LED application market competition. But
the market mechanism PIDA (PIDA) that the wavelength ultraviolet LED is
suitable for fine sensing and other characteristics, high color
rendering index, less heat, high stability of the light source needs,
therefore, remains optimistic in the field of special applications, If
dental handpiece nsk the purpose of sterilization, special-purpose bio-medicine, resin is
hardened, to prevent corrosion of the semiconductor circuit. Like the blue light-emitting diodes, light-emitting diodes black can also be used for indoor growth. UV-LED
with red, green and blue color of the phosphor powder to produce a high
color rendering index of the white light, but the luminous efficiency
and cost price is limited, currently on the market UV-LED, or simply UV
application The main field of the optical band it is difficult to break into the white light applications.
However, subtle features such as sensor having a wavelength of UV-LED, has been used in identifying money. In
addition, LED applications in the medical field, generally require a
high color rendering, less heat, high stability of the light source
demand, which is UV LED noteworthy niche market. Is
around 375nm and 280nm UV light, can be used in air purifiers, water
purifiers, as well as dioxins, environmental hormones, pesticides and
other purification. Photocatalyst, dual wavelength excitation better sterilization, sterilization strong UV 280nm LED is ongoing research. UV
resin curing UV LED light source market is also being gradually
established in 2008, which is the UV spot curing system, equipped with a
mercury lamp and LED lights. Wherein the epoxy resin hardened with mercury, LED lights, used for intraoral camera hardening acrylic resins. However,
the increase in the power of the LED is not used for the frequency
domain of 365nm is converted into heat energy hardening, then heated to
facilitate the epoxy hard although lower power CUVLED, but is gradually
improving, mercury vapor lamp as short life, toxic, the future will be possible to replace the use of LED lights.
