HPR Series
"Brighter" "More uniform" "Easy to use" High-Power Ring Lights
Enhanced light intensity and larger uniform area enables more diversified applications.
Radiation of High-intensity
Diffused Light
Achievement of Larger
Uniform Areas
The use of power LEDs and the unique illumination
structure achieves a high-intensity with uniform diffused
illumination. The HPR Series realized higher light intensity
compared with conventional diffusion ring lights and it
makes possible to use under various situations.
The unique illumination structure irradiates diffused light
effectively from the LEDs. Since there is little change in the
uniform area even if the distance from the workpiece to the
Light Unit will be changed, HPR Series can be used in a wide
variety of environments and for diverse applications.
