Working principle of UVLED surface light source

UVLED surface light source is a semiconductor light-emitting device that directly generates ultraviolet light. The following is a detailed introduction to UVLED surface light source:

1. Working principle and technical characteristics

UVLED surface light source is a light source with a peak wavelength of a certain wavelength in this band, which is formed by integrating high-power LED chips with a light emission wavelength of 200nm to 450nm in a certain proportion.

UVLED surface light source uses light-emitting diodes (LEDs) to generate stable and uniform ultraviolet light, covering a large surface area, so that the photosensitive components in the material undergo polymerization reaction under the irradiation of ultraviolet light and cure rapidly.

2. Advantages

Natural light: UVLED surface light source emits uniform and stable light, with strong light, which can ensure wide coverage of the irradiation area and uniformity of the light spot.

High efficiency and energy saving: The power of UVLED light source is usually between a few watts and tens of watts, which is much lower than the power consumption of traditional mercury lamps, and no preheating is required, it can be turned on and used immediately, which can significantly improve energy efficiency.

Environmental protection and safety: UVLED light source does not contain toxic mercury, does not produce ozone emissions during use, is environmentally friendly, and has low thermal radiation during use, and will not cause thermal damage to the treated materials.

Long service life: The service life of UVLED light source can reach tens of thousands of hours, far exceeding the service life of traditional mercury lamps, reducing the frequency of replacement and maintenance, and reducing operating costs.

Easy operation: UVLED surface light source is usually controlled by touch screen, which is simple and convenient to operate and improves production efficiency.

III. Application field

Electronic components: UVLED surface light source is widely used in the production and packaging process of electronic components, such as the curing of adhesives, which can ensure the firm packaging of components and avoid local overheating to damage precision components.

Optical components: In the manufacture of optical components, UVLED surface light source is used for the bonding and surface treatment of precision lenses and optical equipment to ensure the optical transparency and firmness of the bonding parts.

Printing and packaging: UVLED surface light source is widely used in the printing and packaging industry for the rapid drying and curing of inks and coatings, which can complete high-quality surface treatment in a short time and increase production speed.

Medical equipment: UVLED surface light source is also widely used in the manufacture of medical equipment, such as in the bonding of medical devices and the curing of disinfection coatings, which meets the medical industry's requirements for high safety standards and precise processing.

IV. Selection Recommendations

When selecting a UVLED surface light source, users need to consider the wavelength, irradiation area, power, and heat dissipation performance of the light source according to actual needs. For example, smaller components or fine surface treatments can choose a light source with a smaller irradiation area, while large-scale industrial applications require uniform irradiation over a larger area.
