Here are a few significant facts of Andromeda LED Lighting's “Film-Covered LED Device” Patent:
Our patented technology produces high efficiency of white light and sidesteps two main categories of LED lighting patents in the LED industry-- White Light LED Phosphor and High Power LED Packaging.
Our technology streamlines the manufacture process, thus reducing production costs and increasing product quality simultaneously. The defect ratio is less than 1%!
High luminous efficiency of warm white light
Color temperature deviation is less than 30 degrees. The margin of error in the CIE chromaticity diagram is extremely small, maintaining color consistency.
Because of this design, the light source gives out areal light, as opposed to the light cones by competitors' LED point light sources.
The advantages are 1) less heat generated (warm to the touch) 2) longer lifetime 3) uniform light 4) esthetically appealing 5) maintaining constant light output (lumens) for a much longer duration of time

No phosphor is needed to cover the LED chips. It is replaced by a film covering the LED chips to produce the desired light colors.
