UV LED - Overview

A UV LED is a semiconductor device, similar to a regular LED, that emits light in the ultraviolet (UV) spectrum when an electric current passes through it. Unlike traditional mercury lamps, UV LEDs are solid-state devices that don't use filaments or gas, and they are classified as UVA, UVB, or UVC based on their emission wavelength.

Advantages of UV LED

UV LEDs Are Less Affected by Heat

Unlike UV lamps, UV LEDs do not generate infrared rays, which greatly reduces damage to heat-sensitive materials.

UV LEDs Offer a Shorter Cure Time

Cure times are short (generally 0.1 to several seconds), which shortens production times.

UV LEDs Have a Compact Configuration

UV lamps require extensive cooling and exhaust systems. UV LEDs do not, yielding a more compact configuration. Many of our products rely on simple air cooling, resulting in extremely compact designs.

UV LEDs Protect the Natural Environment

UV LEDs do not require mercury, unlike UV lamps, so there is no emission into the environment. Plus, with significantly lower power consumption, LEDs dramatically reduce CO2 emissions.

Types of UV LED

UV LEDs in the optoelectronics market consists of product ranging from approximately 265nm – 420nm with a variety of package styles including through-hole, surface mount and COB (Chip-On-Board). There are many unique applications for UV LED emitters; however, each is greatly dependent on wavelength and output power. In general, UV light for LEDs can be broken down into 3 general areas. These are classified as UV-A, UV-B and UV-C.
● UV-A: 400 – 315 nm
● UV-B: 315 – 280 nm
● UV-C: 280 – 100 nm

Application of UV LED

Industrial and Cosmetic Curing
UV curing is a process that uses UV light to instantly cure or "dry" inks, coatings, adhesives, resins, and polymers so they solidify without heat.

Analytic Tools
Another UV light application is the UV analysis lamps used to excite the electrons of examined substances, causing them to glow and making certain materials visible to the human eye.

Gemological Field
Ultraviolet (UV) light is an essential tool in gemology, allowing mineral and stone collectors to identify and authenticate gems and minerals.Experts can distinguish natural gems from synthetic or artificially treated ones by observing the fluorescence that some stones, such as diamonds and rubies, emit under UV light.

Sterilization and Disinfection
The medical field uses UV-C radiation, an excellent choice for air and water purification. This process occurs because high radiation destroys the genetic material of microorganisms such as viruses and bacteria, preventing them from infecting humans. This type of disinfection uses ultraviolet light in the food production and health sectors, among others.

Indoor Gardening
UV LED lights play an important role in indoor urban gardening for fruits, vegetables, and other plants grown for human consumption. UV LED lights increase the production of polyphenols, which are believed to have antioxidant and anti-aging qualities.

FAQ

Q: What are UV LEDs used for?

A: UV LEDs are used for a wide range of applications, including disinfection (water, air, and surfaces), industrial curing (paints, coatings, and inks), medical therapies (treating skin conditions), and analytical and forensic purposes (detecting blood, validating documents, and scientific analysis). They are also used in specialized areas like plant growth for horticulture and cosmetic tanning.

Q: Do I need to take protective measures when using UVA LEDs?

A: Yes, UVA LEDs will emit radiation, and if prolonged exposure, it can cause irreversible damage to our skin and eyes. To avoid accidents, do not look directly at the UV LED modules or stay in the area for extended periods. If necessary, please wear UV protective goggles for eye protection.

Q: Does it support the customization of UV LEDs with other wavelengths?

A: Yes, we support customization of any wavelength of UVA, UVB, and UVC, but the specific led packaging process needs to be determined according to customer needs. Please contact our customer service to confirm the details.

Q: Is this model of UV COB LED waterproof?

A: The COB's light-emitting surface and components have some waterproof properties due to glue sealing, but they are not completely waterproof. COB improves waterproof performance of the lamp, serving as an auxiliary. Additionally, solder joints should be sealed to prevent short-circuiting upon contact with water.

Q: May I have some free samples?

A: Yes, for samples in stock or with low cost, we can provide 1-2pcs samples for customers to test. And for customized styles or those with large cost, we have to charge a certain sample fee based on cost, thanks for your understanding!

Q: How to place an order? Is there a minimum order quantity requirement?

A: For spot styles, generally no MOQ is required; but for customized types, usually MOQ≥200pcs is needed. Please contact us to confirm the details and purchase matters.

Q: Do you offer volume discounts?

A: Yes, we provide discounts for large orders. Contact our sales team for a customized quote.

Q: Is there a warranty for your products?

A: Yes, all products come with a warranty which varies by model. We will repair or replace defective items during the warranty period.

Q: How do you handle complaints?

A: We take complaints seriously and will investigate promptly, keeping you updated until a resolution is reached.

Q: What is your sample policy?

A: If we have stock, we can provide samples, but the customer must pay the sample fee and express fee Question

Q: Have you tested all your goods before shipment?

A: Yes, we will conduct 100% test before delivery, and we will send detailed photos of parts for your approval Question .

Q: How can you maintain a long-term good relationship with our business?

A: We maintain good quality and competitive prices to ensure the interests of our customers.
