Why UV LED Light Source With Constant Current Drive Power?

Because the constant current source drive, do not need in the output circuit series current limiting resistance, LED through the current is not affected by the external supply voltage change, environmental temperature change, as well as LED parameter dispersion, so that the current can maintain constant, full play of various excellent characteristics of LED.

LED constant current power supply is adopted to supply power to LED lamps. Due to the automatic detection and control of the current flowing through LED during the power supply, there is no need to worry about too high current flowing through LED in the moment of power supply, and no need to worry about the load short-circuit burning power supply.

Newest Introduction And Application For UV LED Light Source Equipment

UV LED light source system can quickly cure photo-included binders, thus avoiding the use of 
volatile binders, very suitable for medical applications. Using UV curing glue provides many 
advantages, such as energy saving, shorter curing time, increased productivity, and easy automation. 
At present, UV Drying machine has been use in anesthesia mask, syringe, catheter, intravenous 
infusion tube, vascular implant accessories, endoscope, arterial positioning, tube-like drainage 
device, tracheal tube, blood oxygenator, hearing aid, detection, monitoring, as well as image 
equipment and bio-chip applications.

Professional UV Light Sterilizer and Disinfection Technology

The application of UV Curable Adhesive Systems in Medical field :
1.Beauty
Mainly for easy to acne, oily skin, pores or dull skill tone and so on play a role.
2.Skin disease
At present, UVB is the best therapeutic band for skin diseases in the market. The UV LED device is 
small in size and easy to carry. Whenever and wherever possible to treat vitiligo, psoriasis, eczema 
and other intractable skin diseases.
3.UV Sterilization
The working principle of UV Light Sterilizer and Disinfection is to use the high energy of ultraviolet 
spectrum to destroy the structure of microorganisms, which has a strong bactericidal effect, so as t 
achieve the purpose of disinfection. At present, UV LED lights are widely used in medical units and 
catering systems for sterilization.
4.Dental Equipment
UVC and UVA band produced by domestic famous brands are used as ultraviolet light source to 
make UV LED deep UV toothbrush sterilizer.

Production and application of six medical products :
1.UV curable cardiac stent trocar
2.Manufacture and assembly of blood aerators
3.Needle bushing assembly
4.Conveyor casing and joint assembly
5.Insulin pen UV light solid bond
6.UV adhesive curing of endoscope

High Power UV Light Curing Equipment for Bonding

Characteristics of UV Light Curing Equipment applied in medical treatment :
1.Comparison between high-power high-end purple UV LED sterilization lamp and ordinary low 
voltage lamp :
A.Compared with the traditional UV lamp, its unique coating ensures no transmission loss of quartz 
glass, and its service life can reach up to 16,000 hours. At this time, the output of UVC can still 
reach 85% of the initial UV power.
B.High efficiency, long life and low operating cost, will become an economic alternative to 
medium-voltage lamps. They save energy and produce very little heat.
C.UV output 10 times the generally low UV lamp, working temperature up to 90°, the highest UV LED 
output can reach 16,000 hours of long life. Use less lamp to be able to achieve antiseptic effect, 
reduce first outfit and cost charge.

2.Advantages of UV LED Sterilization and Disinfection in toothbrush sterilizer
A.UV LED sterilization, instant high efficiency, can achieve 99% sterilization rate in 2 minutes.
B.Physical sterilization, no pollution, no smell, no side effects.
C.UV LED energy consumption is very low, saving battery consumption, compared with traditional 
cold cathode, energy saving 80%.
D.The actual service life is much longer than mercury lamp.
E.The actual service life is much longer than mercury lamp.
F.Extremely high surface output brightness, is 100to 1000 times of mercury lamp in the effective 
band unit area output.

3.The advantages of traditional UVB in the treatment of skin diseases were compared
A.The traditional UVB spectrum is a composite light of 310nm, which contains harmful composite
 light that patients do not need, while the ultraviolet light of UVB UV LED lamp emits a laser that is 
close to a single wavelength of 310nm, which is a real narrow spectrum UVB ultraviolet light. 
Therefore, it can better focus on the skin lesions.
B.The ultraviolet light of UV LED lamp belongs to the output of cold light source, which solves the 
problem of ordinary UVC light source overheating, with less side effects, not easy to blister, safe and 
comfortable, suitable for patients of any age.
C.The life span of UV LED lamp is longer than that of traditional UVB lamp. Compared with patients, 
it is more economical and more affordable, with stable output power and not easy to attenuate.
D.Targeted therapy focuses the energy on the lesion and can reach the lesion directly. UV LED light 
power is higher than traditional UVB power.
E.The unique lens technology enhances the UV light purity and precision of UV LED lamp and improves 
the curative effect.
