Light output stability
It is well known from conventional halogen lights (QTH) that the curing performance is
strongly dependent on the bulb. Towards the end of the bulb’s lifetime the output is seen to
drop dramatically. As this can not be checked automatically, it is of outmost importance to
test the QTH curing lamp on a regular basis in order to detect any deterioration in its curing
performance. The LED technology offers the advantage that the LED light source does not
deteriorate over the life time of approximately 10.0000 hours and therefore does not require
maintenance or constant monitoring.
As shown in Figure 3, a fully charged battery provides approx. 150 ten-second cures
(approx. 25 minutes operating time) with constant light output. Therefore, under most
conditions of use, the device only needs to be recharged over night.
When the battery light flashes red (fast), the battery needs to be recharged. Another
2 minutes exposure time is then left for completion of the treatment. Light output is not
reduced during this period. After these 2 minutes, the device switches off automatically and
continues to flash red (slowly) indicating the need to recharge.
