Uniform curing of three-dimensional products requires a departure from the narrow focused, half-ellipse systems originally designed for two-dimensional curing. To uniformly and economically cure a wide range of 3-D product, a useable level of curing energy must be focused with a depth of field as wide as possible. Development for CON-TROL-CURE®'s 10 INCH FOCUS UV LAMP REFLECTOR HOUSING began with Lighthouses higher efficiency reflector approach. Then, we improved it with variable length geometry to deliver high energy concentration with a significantly increased depth of field. By varying the length of the curing energy focus, the light within the UV lamp is initially reflected in wider angles resulting in a more vertical concentration of energy below the lamp in the curing zone. This concentrated focus and increase in energy combine to deliver an optimal 3-D curing envelope. In addition, since the curing energy delivered to the product is closer to perpendicular than other systems, more energy will penetrate and cure the coating, and less energy will be reflected by the coating. The accompanying diagram shows a Lighthouse LV lamp using a variable length reflector to achieve a 10 energy focus (see diagram #3). By extending the focus, the effective curing depth of field has been increased to more than five inches (diagram 3, item A), an increase of almost 500% when compared to the traditional half-ellipse reflector system. Using the variable length reflector system, a curing system can be constructed with a specific depth of field to deliver maximum curing energy custom suited to a customers application.
