High Output LED Ringlights
for space critical applications
The 4200 Series of ringlights represent the latest in LED technology.
The units are less than 25 mm thick and can fit in to tight locations that other
units can not. Some of these units are comprised of a large number of surface mount
LEDS arranged in compact squares. And other units are constructed of
larger circular LEDS arranged in radial ring patterns. The smallest
ringlights have a 38 mm outer diameter and a 15 mm inner diameter. The
largest standard size ringlight is 140 mm OD and 95 mm ID.
Standard 4200-R70/39R Red LED Backlight
These units provide flat illumination fields designed to work at a specified
distance from front surface to the object, this is referred to as the
"working distance" and is abbreviated WD on the chart below. The
larger the size of the ring light the more LED provided and the greater the
operating power requirements. All units operate on 12 VDC and the
necessary current requirements are listed in the chart below.
Shown above are the 70 mm diameter ring (39 mm opening)
illuminated as viewed off-axis.
