UVLED curing lamps by light energy → electrical conversion, making high-power ultraviolet LED diode chip to produce high purity 365nm, 385nm, 395nm, 405nm monochromatic UV, uv curing energy is highly concentrated in the desired wavelength band.

UVLED ultraviolet light emitting diode that is usually common UVLED wavelength of 405nm, 395nm, 385nm, 365nm, 305nm, 278nm, etc.

For UV curing glue is mainly effective wavelength 365nm, and for the main ink curing wavelengths of PCB exposure machine has 385nm, 395nm, 405nm and the like. The main wavelength for UV disinfection are 305nm, 278nm, the shorter the wavelength, the stronger sterilization. So-called UVLED light equipment mostly refers to 365nm, 385nm, 395nm, 405nm wavelength UVLED light source device.

New UV LED curing system, by electrical → light energy conversion makes LED (LG Korea imports) high-power UV diode chip produced high purity 365nm, 385nm, 395nm, 405nm monochromatic UV light, high concentration of energy in the ultraviolet curing glue needed wavelength band. Application areas: electronics, precision parts, heads, optical lenses, liquid crystal display panels, micro-motor, medical supplies, crafts, fiber optic connectors, LCD, LCD, motor, hard drives and other emerging fields can apply a wide range of applications. Or supporting the use of automatic or manual dispenser. Fiber is the traditional high pressure mercury lamp spot light machine replacement.

1, the product is different from the traditional high pressure mercury lamp type curing equipment; UV curing machine produced by traditional light brightness looks very bright, high in calories, in fact, it's a very wide spectrum, a UV spectrum really effective curing effect only part of its energy, a significant part in the visible segment (stray light) and generates heat, serious injury to the operator's eyes and easy to workpiece thermal deformation

Using LED light source illumination, and the issue is a high purity 365nm, 385nm, 395nm, 405nm monochromatic UV light, it belongs to the cold light source; workpiece temperature rise only about 3 degrees, does not deform the workpiece, which has a high concentration of energy in the effective solidification of a UV spectrum, which is UV-LED spot light intensity of ultraviolet light, although only 500mw or so, but its practical effect high pressure mercury lamp and light intensity 1500-2500mw curing effect comparable to the main reason, usually makes cure time 0.5 to 5 seconds.

2, low production costs: As a result of the LED light way, life of up to 25,000 hours (continuous light life) energy-saving design, only when required, by irradiating lights, low power consumption: about 50W. (Traditional UV curing machine, lamp life is typically 1000 hours, high power consumption, Power 30KW.LED point light body small and lightweight 27 * 12 * 18cm3, it can be easily integrated into an automated assembly process, or as a complete desktop system can also be installed in small devices .LED irradiation head through the computer CPU control, according to the actual need to select manual or automatic control operation, and the time required to set their own light irradiation (accurate to 0.01S) further support the needs of high-precision engagement, reducing time error .LED curing equipment manual operation of almost no heat, non-friable, no mercury; do not need maintenance cost (conventional curing lamp operating temperature: 500 ℃, brittle, containing mercury; maintenance costs: a number).

3, UV-LED is equipped with a special condenser lens assembly also makes it a high concentration of energy in the solidification point to improve the efficiency of UV-curing adhesive, can drive 8 channels (each device can be installed eight LED tube), each independently controlled, for users to reduce costs, while increasing the irradiated area.

UVLED Categories

UVLED SPOTLIGHT: Usually a UVLED lamp beads (in most cases as a single, but also multiple chips) to emit light, forming a point, called point source

UVLED line source: Usually multiple UVLED lamp beads (but also integrated chip) in a row, the linear light emitted form a line, called linear light source

UVLED surface light source: a plurality UVLED is formed in accordance with the different combinations of lamp beads arranged in rows and columns, emits light of various shapes surface, forming a surface, called the surface light source.

UVLED wavelength range

(1) UVA wavelength 320-390nm, also known as long-wave ultraviolet light shading effect. It has a strong penetration, it can penetrate most transparent glass and plastic. Sunlight contains ultraviolet There are more than 98% of the ozone layer and can penetrate clouds reach the Earth's surface, UVA can direct skin's dermal layer, destruction of elastic fibers and collagen fibers, our skin tanning. 360nm wavelength UVA rays meet the phototaxis response curve insects, and can be made trap lamp. 300-420nm wavelength UVA rays through special tinted glass tube can be completely cut-off visible light, the only radiation to 365nm as the center of near-ultraviolet light can be used for mineral identification, stage decoration, paper money and other places.

(2) UVB wavelength of 280-320nm, also known as medium wave ultraviolet erythema effect. Moderate penetration, its shorter wavelength part will be transparent glass absorbed ultraviolet sunlight contains largely absorbed by the ozone layer, less than 2 percent to reach the Earth's surface, in the summer, and the afternoon will be particularly strong. UVB erythema ultraviolet radiation on the human body has a role in the body can promote the formation of mineral metabolism and vitamin D, but the long-term or excessive radiation can make the skin tan, and cause redness and peeling. Health UV lights, grow light is emitted through the use of special purple glass (254nm or less impervious to light) and peak at 300nm is made near the phosphor.

(3) UVC wavelength of 280nm or less, also called short-wave ultraviolet sterilization. Its ability to penetrate the weakest, most impenetrable transparent glass and plastic. Shortwave ultraviolet sunlight contains almost completely absorbed by the ozone layer. Shortwave ultraviolet radiation on the human body great harm, short irradiation can burn the skin, long-term or high-intensity irradiation can also cause skin cancer. UV germicidal UVC light is emitted shortwave ultraviolet light. UVD band, wavelength 100 ~ 200nm, also known as vacuum ultraviolet rays.

(4) UVV wavelength at 390nm or more.

UVLED advantages compared to traditional mercury lamp
