Sure, such a lamp looks like is very important. But in the world of lighting, it’s more significant to be aware what that lamp are capable of doing. It’s especially important to lighting designers and electricians.
You may have encounter graphical representations such as the ones you see below and wondered what they mean. Let’s take a peek:
A polar curve is a graphical representation of LED measurement in numerous directions. The values are indicated in cd/klm (Candelas per 1000 Lumens) so have to be multiplied through the luminous flux of the lamp used.
The solid line shows the distribution inside the transverse plane. The dotted line shows the distribution within the axial plane. These curves give you a visual guide about the lighting distribution.
Beam cones indicate light’s beam spread from the luminaire. All Aurora cone widths will be to 50% of peak beam illuminance. All values are real values as being an average across the area shown without having maintenance factor applied.
These cones present you with another design of visual guide for the light distribution how the luminaire provides and are normally only suited for direction lamps and fittings.
Within dedication to proving the lighting performance of our products, we’ve invested in both a LM-79 Test and integrating sphere, contained within temperature and voltage controlled environments in compliance with LM79-8.
Aurora performs superior in-house testing with the own, state-of-the-art photometric sphere and goniophotometer. Our testing activities meet the requirements defined in LM79. The LM79 standard recognises that solid state LED lighting is evolving, and therefore the testing of such products should be standardised and yet comparable. LM79 mandates the exact calibrations necessary and required product stabilisation procedures. We continually update our testing regime to keep before dexfpky08 mandatory requirements and greatest practices.
Our near-field imaging Spectroradiometer combines a motorised stage with an imaging photometer to do near-field angular analysis of the luminance and colour from LEDs. The inner software then scales this info to luminous intensity data through which photometric data files are set up – either IENSA (ies) or ELUMDAT (ldt) format.
Our Labsphere Light Measurement Integrating Sphere is made for the measurement from the total flux production of lamps as well as other light sources. It’s 76 inches in diameter having a highly relective, durable Spectraflect interior coating that may accommodate lamp sizes from sub-miniature incandescent and LED lamps as much as a 4-foot linear fluorescent lamp. It conforms to the recommendations of CIE publication 84.
