There is more to lighting than meets the eye

Les Kacev is passionate about lighting education, measurement and the quality of light. He has run seminars, workshops and webinars for utilities, associations, universities, LED manufacturers, vendors, distributors, and conferences. A few examples follow

The human eye is truly our window to the world. Not only does it contain rods and cones which stimulate our vision, but it has recently been discovered that the eye contains a variety of intrinsically photosensitive retinal ganglion cells known as ipRGC which are involved in non-visual functions. Light and light quality play an immensely important role in stimulation of ipRGCs and in so doing determine our mood, sleep patterns, productivity, health and  general wellbeing. Light exposure plays an important part in our mental health.

Not only does light [natural and artificial] affect humans, but its impact on fauna and flora is only now being appreciated. Its influence on mammals, birds, bats, insects, fish and plant life has opened up a new branch of science.

The Lighting Passport spectrometer is a Bluetooth device requiring version 4.0 or better to send information to an iPhone, iPad, iPod Touch or Android phone/tablet.

Although the Flagship Set is an integrated device and the Lighting Passport is physically connected to the iPod Touch, it can readily be “unclipped”. Communications is still accomplished via Bluetooth as with the Standard Set and Essence. By consisting of two separate devices, flexibility is increased.

  • The user with the smart device can operate the Lighting Passport from approximately twenty feet away.
  • The Lighting Passport can be placed and correctly oriented in “tight” areas with limited access or size restrictions.
  • In quality control applications, the Lighting Passport can be mounted on a production line at a fixed distance from a conveyor ensuring accurate and consistent readings with remote operation.

There are several methodologies for transferring data from a smart phone or tablet after it has been saved.
There are two methodologies common to both Apple and Android devices

  • Data can be emailed using the device’s regular email program. This can be accomplished via a mobile network or the internet. Some email programs will create “zipped” files which will then have to be unzipped and the text file extracted for manipulation.
  • NEW During the setup process one can define a user network and transfer data automatically via WiFi from smart device to a specific folder designated to receive data.

Apple devices have the ability to backup via iTunes.  Data from the backup file can be transferred to the Lighting Passport data folder.

When Android devices are connected to a PC via a USB cable, they are recognized as a separate drive. Data can be copied from this drive to any designated folder.
