The 6868 high-power UVA LED bead is professionally developed for industrial continuous photocuring scenarios. This SMD packaged ultraviolet light source adopts four LED chips connected in series and is fitted with a high-transmittance 60° quartz focusing lens.

Different from ordinary silicone lenses, quartz glass possesses excellent heat resistance and powerful anti-ultraviolet aging capability. It will not turn yellow after long-term continuous UVA irradiation, effectively avoiding luminous attenuation caused by lens aging and securing sustained stable ultraviolet output.

The optimized 6868 packaging structure achieves excellent heat conduction performance to rapidly export heat generated during long-hour operation. The 60° focused beam angle concentrates ultraviolet radiant energy, raising irradiance level and greatly enhancing curing efficiency for UV glue, resin, printing ink and other materials.

UV resin photocuring, UV adhesive curing, screen printing ink drying, PCB exposure equipment, UV testing instruments, nail curing equipment and automated industrial photocuring production lines.

Constructed with four series-connected chips and equipped with a 60° quartz focusing lens, the 6868 UVA LED bead serves as a reliable high-power UV light source for industrial curing. Quartz optics solve the yellowing defect of silicone lenses, supplying concentrated and consistent UVA radiation for continuous industrial production.

Q: Why choose quartz lens instead of silicone lens?

A: Silicone lenses gradually degrade and yellow under persistent UVA radiation. Quartz glass can withstand long-term ultraviolet exposure without discoloration, maintaining high UV transmittance and extending the service life of LED beads.
