Solution

Yajiang evaluated the color LED options available and

determined that Lumileds offered the best solution in terms

of wide color options, color consistency, quality of white light

and friendliness to secondary optical design. The first two

products developed in the Stager line are the Fresno Fresnel

spotlight and the Eclipse Profile spotlight. The Fresno utilizes

RGBLA LEDs with a single optic per LED for maximum color

control. The Eclipse Profile spotlight is a LED module spotlight

with RGBLA LEDs.

The LUXEON C Color Line is specifically designed for flawless

color mixing. Each LED, regardless of color, has the same

focal length, leading to a consistent radiation pattern from

secondary optics. The LED source size is 2mm x 2mm,

enabling compact design on the PCB. A low dome over

the LED improves light extraction and maximizes punch

in spotlights.

The LUXEON C Color Line also features the industry’s lowest

thermal resistance substrate (2.8 °C/W), which allows the LEDs

to be driven harder or heatsink costs to be reduced. In stage

lighting applications, sometimes a quiet set is needed and

lighting fans must be shut off. The cooler operation enabled

by the LUXEON C, together with Yajiang’s heatsink design,

provide such system flexibility during performances.

Results and Benefits

The Stager spotlights are designed to exceed user

expectations for state-of-the-art stage lighting. By combining

the color richness of the LUXEON C Color Line with the Stager

optics, heatsink and overall sleek design, lighting professionals

enjoy the highest quality color mixing and white light in a

compact form factor.

The Stager spotlights are an excellent example of

adaptiveness in a single platform for multiple stage lighting

applications. The product series can deliver consistent color,

flawless color mixing and a high color gamut due to the

expansive color options in the LUXEON C Color Line. The

quality of white light is critical, as well, and the spotlights

deliver a wide color temperature range (2700K-6500K) with

CRI greater than 85 for accurate white light depiction.

“The color richness of the LUXEON C

Color Line brings flexible color mixing

and a high color gamut. It also delivers

the best quality of white illumination

with high CRI.”
