The action of (b) lighting monitoring arrangement
In this lighting monitoring arrangement 150; CPU 153, substantially according to the voltage of the king light 11A detected, judges that the state of king light 11A is normal or abnormal (judgment means), when being judged as abnormal; perform hand-off process, power to stand-by lamp 11B.In this case, control part 155 plays function as monitoring arrangement.
Figure 24 is the flow chart of the main process that lighting monitoring arrangement 150 is shown.In a step 101, CPU 153 is by the normal voltage V by the king light 11A detected by the process shown in following Figure 25 f_dayas reference voltage value (a reference value) V freg.Implication about this step 101 will be described later.A reference value V freg, such as, be the forward voltage of LED.
CPU 153 obtains the voltage V of king light 11A from A/D converter 152 f(step 102).CPU 153 determining reference value V fregwith the voltage V detected fbetween difference | V freg-V f| whether less than the threshold value beta being stored in advance in storage part 154 (step 103).That is, the voltage V of CPU 153 couples of king light 11A frelative to a reference value V fregchange monitor.When this changing value is less than threshold value beta, is considered as king light 11A and is in normal condition, return treatment step 101.
Such as, if the total voltage of six LED 15 is about 20 (V), so threshold value beta can be set as about 2 (V).
CPU 153, when this variation value is more than or equal to threshold value beta, judges that king light 11A there occurs exception, such as output abnormality signal (step 104).In this case, due to the overtension of king light 11A, can infer and there occurs open fault.
Thus, CPU 153 stops the driving (step 105) to king light 11A, starts to drive stand-by lamp 11B (step 106).In other words, CPU 153 stops powering to king light 11A, switches to and powers to stand-by lamp 11B.In this case, CPU 153 and drive division 156 play function as switching device shifter.
As mentioned above, the lighting monitoring arrangement 150 involved by present embodiment, not detects the electric current by incandescent lamp bulb, but detects the voltage V of the light source portion with solid-state light emitting element as in the past f, therefore, it is possible to positively detect the generation of the exception of its light source portion.
Figure 25 show perform before the main process shown in Figure 24, to the flow chart of the process after such as modulator 300 (i.e. king light 11A) drops into power supply.
Such as, CPU 153 before the dump of the king light 11A by modulator 300, by power supply drop into before store voltage V fas the voltage V of last time f_dayread, and be stored in storage part 154 (step 201).CPU 153 obtains the voltage V that power supply drops into the king light 11A that rear primary detection goes out from A/D converter 152 f(step 202).
CPU 153 judges last voltage V f_daywith voltage V fbetween difference | V f_day-V f| whether less than the threshold alpha being stored in advance in storage part 154 (step 303).
CPU 153, works as difference | V f_day-V f| when being less than threshold alpha, judge that king light 11A is in normal condition, cover and preserve last voltage V f_day(the first magnitude of voltage) (step 204).On the other hand, difference is worked as | V f_day-V f| when being more than or equal to threshold alpha, CPU 153 judges that king light 11A there occurs exception, replaces voltage during this exception, the V last by voltage time normal f_dayas current detection voltage.
Then, CPU153 starts the main process illustrated in Figure 24, by the V stored f_dayas a reference value V freg(step 101).
