LED Driver Circuit with Temperature Compensation

In another project directed by Carmanah, the engineering intern devised a strategy that would maximize the operating efficiency of the LEDs over the life of the product they were integrated into. The net effect would be to maintain a brightness that complies to the end user's expectations while broadening the number of sites the product can be deployed into. With better operating efficiencies, it would be possible to install solar powered marine lanterns at higher and lower latitudes than was previously possible. Broadening the market that Carmanah has access to provides a benefit for both Carmanah and the end user that had no alternative to solar powered lighting.
