Latest Patents

One of Kopec's latest patents is a method of operating an LED lighting system. This innovative system operates with a time-based process, where the LEDs are initially energized at full power. After a predetermined time period, which is carefully selected to prevent the junction temperature of the LEDs from reaching critical levels, the current supply is gradually reduced to a steady-state supply. This steady-state current is maintained as long as the light remains on. If the light is turned on again before the LEDs have fully cooled down, the full-power time period is adjusted accordingly.

Another significant patent is the adaptive defrost controller for a refrigeration device. This system and method control the automatic defrost of a refrigerator by adaptively scheduling the defrost cycle during periods of low compressor activity. The adaptive defrost controller analyzes stored data to create a profile of compressor activity over time. By distinguishing between high and low compressor activity times, the defrost cycle is scheduled based on the analyzed data, enhancing the efficiency of the refrigeration device.
