Class: LightEmittingDiode

The LightEmittingDiode element is used to describe various kinds of LED lamps. As the LightEmittingDiode is inside a LightSource it already has available the values from ManufacturerSpec (Manufacturer, Model, SerialNumber, LotNumber) And the values from LightSource which includes Power in milliwatts We have looked at extending this element but have had a problem producing a generic solution.

Possible attributes talked about adding include: Power in lumens - but this is complicated by multi-channel devices like CoolLED where each channel’s power is different Wavelength Range - not a simple value so would require multiple attributes or a child element Angle of Projection - this would be further affected by the optics used for filtering the naked LED or that combine power from multiple devices These values are further affected if you over-drive the LED resulting in a more complex system Another issue is that LED’s may not be used directly for illumination but as drivers for secondary emissions from doped fiber optics. This would require the fiber optics to be modeled. Thanks to Paul Goodwin of Applied Precision of information about this topic.
