LED Spot W
The Honle LED Spot W is a super high power, compact, and versatile LED flood-type system ideal for fast curing UV adhesives and potting compounds. The Spot W produces a homogeneous pattern of UV or visible light in a 20mm x 20mm area.
The wider area of irradiation of this compact LED floodlight permits curing of larger adhesive bondlines and potting surfaces. Smaller components may also be batch cured with the LED Spot W. With some similarity to the Honle LED Spot, the LED Spot W unit is more than twice as powerful. Water cooling permits curing intensities to be generated as high as 25,000 mW/cm2 (405nm). This permits very short curing cycle times in high volume production. The closed-loop water chilling system is easy to maintain, utilizing flexible tubing to circulate water from the chiller to the LED Spot W head. LED life is 20,000 hours, or more.
The LED Powerdrive control unit is capable of operating up to three LED Spot W heads. They can be programmed to work simultaneously, in sequence, or totally independently to create up to three separate workstations. A power adjustment feature provides the ability to reduce output intensity from 100% to as low as 2% for maximum operating efficiency. Process Flow Control permits full programming of the curing cycle including exposure series using different intensities and dwell time for parts handling.
This system requires no warm-up time and provides instant on/off control. Using an external control, cycle time can be set for less than 100 micro seconds. The LED Spot W can also be programmed for continuous operation. Programming and process monitoring can be accomplished from a remote PLC. A fault warning will be displayed if a single LED fails to operate in the array.
The LED Spot W flood unit is available with LED outputs of 365, 385, 395, 405, and 460nm wavelengths. Typical applications include the curing of UV adhesives, potting materials, and coatings associated with component assembly in the medical, micro-electronics, mobile device, and transportation industries.
