Advantages of UV LED Area Light Sources

Single-wavelength UV light output, with no harmful thermal effects

Utilising high-power LEDs to emit a single-wavelength light source, the product is highly targeted and efficient.

The influence of light emitted by sources other than the main wavelength has been eliminated.

In particular, as it does not emit infrared radiation, it significantly reduces the thermal impact on the workpiece. It is the ideal light source for high-precision curing, where thermal effects are a major concern.

For example, the assembly of ultra-thin resin lenses. Low power consumption, energy-saving

It achieves a low power consumption equivalent to just a few tenths of that of a UV mercury lamp. The product can significantly reduce annual energy consumption and waste emissions.

Reduces environmental impact. Flexible layout, space-saving

By using UV-LEDs, the unit is approximately 90% smaller than UV mercury lamp models. It is also significantly lighter, eliminating concerns about installation space and allowing for greater freedom in layout.

The irradiation heads can be controlled individually or simultaneously, thereby reducing capital expenditure on equipment

Select the number of irradiation heads as required; multiple conventional mercury UV lamps can now be replaced by a single UV LED line or area light source.

This reduces capital expenditure, whilst the irradiation heads can be controlled individually or in unison, depending on on-site process requirements.

Consistent output accuracy

By employing unique heat dissipation technology in the UV-LED sector, we have developed a cooling method that balances high light output with a long service life, minimising drift and ensuring stable illumination.

Long service life, reduced running costs

Compared with UV mercury lamps, LED lamps have a significantly longer service life. This is precisely what characterises LED technology. Unlike UV mercury lamps, which must remain switched on at all times, UV LEDs can be switched on and off instantly; consequently, the difference in actual service life is even greater.

By utilising a proprietary optical system, this UV irradiation minimises variations in light intensity across a wide area. It helps to prevent curing,

Curing deformation of drying spots and adhesives, assisting customers with quality management.

Detailed Areas of Application: UV LED area light sources measuring 100 × 100 mm are used in the following industries in which you operate:

 

1. UV-curable screen-printing varnish

It can be used for spot varnishing or full-surface varnishing. The varnished surface features vibrant, glossy and transparent colours with a photographic finish; it is wear-resistant, does not peel or curl, and is used for the decorative and protective finishing of high-end packaging.

Product features:

a. The product is odourless, solvent-free, causes minimal skin irritation and cures quickly.

b. The product has excellent defoaming and levelling properties, making it suitable for high-speed printing on automatic printing presses.

c. The product exhibits excellent adhesion and fold resistance on gold and silver cardstock.

d. The product’s viscosity is adjustable to suit screens of different mesh counts, making it suitable for printing on a wide range of wine boxes and cigarette packets.

2. UV plastic varnish (suitable for hot foil stamping)

Primarily used for roller coating on the surfaces of PE and PP films or sheets; suitable for gloss finishing on toothpaste tubes, PE tubes and self-adhesive film surfaces.

Product features: Resistant to yellowing, low odour, abrasion-resistant, high gloss and good flexibility. This range also includes a UV matt varnish.

3. UV varnish for CD protection

Disc protective coating is a key material in disc production and is crucial to disc quality; it must adhere well to the disc’s reflective metal layer, be highly compatible with printing inks, and exhibit good performance at both high and low temperatures,

Excellent wear resistance: our company’s Shenzhen Deshengxing Technology products possess the aforementioned characteristics.

4. UV-curable adhesives

Features: A single-component UV-curing adhesive; UV-curing adhesives are not only easier to use than traditional two-component thermosetting adhesives, but also offer the following features.

Optical properties: The liquid crystal adhesive is crystal-clear; after curing, its light transmittance is ≥90%.

Adhesive properties: Low volume shrinkage after curing, high elongation and high adhesive strength.

Weather resistance: Once cured, the adhesive exhibits excellent weather resistance; it does not yellow when exposed to prolonged ultraviolet radiation and has high resistance to both high and low temperatures, making it suitable for use in a temperature range of –50 to 80 degrees Celsius.

Uses: For the rapid bonding of transparent materials such as transparent plastics, glass and metals, as well as non-transparent materials such as plastics, ceramics and rubber; the curing time can be as fast as 1 second, and the bond strength is adjustable.

, suitable for bonding, encapsulation or mounting applications involving optical discs, electronic components, optical communication components, biological products, furniture and the like.

a. UV disc adhesive: UV disc adhesive, suitable for the production of DVD-5 and DVD-10 discs.

b. Glass–aluminium alloy adhesive (UV-curing adhesive): Widely used in optical instruments, medical devices, handicrafts, furniture and the construction industry, for bonding glass to metal,

Bonding of glass to glass, metal to metal, etc.

Instructions for use: First, clean the surface of the object to be bonded thoroughly and allow it to dry. Apply a small amount of adhesive to the surface of the object to be bonded, then press the surfaces firmly together to remove any air bubbles from the adhesive layer, ensuring that the adhesive layer is less than 25 μm thick,

After application, cure the resin by exposing it to a high-pressure mercury lamp (power: 60 W/cm) at a distance of 10 cm for 10–20 seconds (curing times may vary slightly depending on the light-curing material and the lamp used). The properties of the light-curing resin will reach their optimum after half an hour.

5. UV-curable soft rubber

Uses: To provide a protective, transparent finish for trademarks, badges, labels, etc.

Features: The liquid adhesive is stable in storage and cures rapidly upon exposure to ultraviolet light; the cured adhesive is transparent and elastic, and is scratch-resistant; indentations and scratches disappear of their own accord.

Instructions for use: Once the resin has been dispensed, it may be placed in a light-curing oven for curing. The resin layer should not exceed 2 mm in thickness. Curing conditions: high-pressure mercury lamp, 60–80 M/cm; curing time: 10–25 seconds.

6. UV-cured marble-effect coating

UV marble varnish, used for decorating marble, engineered stone, ceramic stone and similar materials, provides a bright finish with a distinctive effect; it reduces energy consumption in stone production and improves production efficiency.

7. UV-curing adhesive

For bonding glass to glass, glass to metal, plastic to plastic, and plastic to metal.

Features: Fast curing, high bond strength, no yellowing, no bubbling. Cures within 20 seconds in sunlight.
