When the light source module 100 being equipped with the resistor 106 being used in current detecting is connected to ignition device 10a, carry out the work identical with the ignition device 10 of the first execution mode.More specifically, the first lead-out terminal 16c of ignition device 10a is connected to the first splicing ear 105a of the connection portion 104 of light source module 100 via the first splicing ear 15a of connecting portion 14.The second lead-out terminal 16d of ignition device 10a is connected to the second splicing ear 105b of the connection portion 104 of light source module 100 via the second splicing ear 15b of connecting portion 14.Current sense input 50 is connected to the light source 102 of light source module 100 and the connected node 103 of resistor 106 via the 3rd splicing ear 15c of connecting portion 14 and the 3rd splicing ear 105c of connection portion 104.The ignition device 10a of present embodiment has 2 paths in the same manner as the ignition device 10 of the first execution mode, namely has main path Pm and secondary path Ps.Main path Pm is: anode → resistor 106 → the second splicing ear 105b, 15b of first lead-out terminal 16c → the first splicing ear 15a, 105a → light source 102 → second lead-out terminal 16d → resistor 51.In addition, secondary path Ps is: anode → node the 103 → three splicing ear 105c, 15c of first lead-out terminal 16c → the first splicing ear 15a, 105a → light source 102 → current sense input 50 → resistor 71 → resistor 51.In the ignition device 10a of present embodiment, the electric current flowing through light source 102 flows through the main path Pm comprising the resistor 106,51 be connected in series.The detection voltage Vdet1 that the electric current being supplied to light source 102 generates based on the series impedance of the parallel resistance value of resistor 71,106 and the resistance value of resistor 51, by control part 12 current constant control.Detect voltage Vdet1 and be input to control part 12 via current sense input 50.The detection voltage Vdet1 being input to control part 12 such as compares with the reference power supply Vref of the inside of control part 12, and is controlled to consistent with reference voltage V ref by control part 12.
In the ignition device 10a of present embodiment, the resistance value being built in the resistor 106 of light source module 100 can be the resistor of arbitrary value.That is, the resistance value of resistor 106 can be set to 0 Ω ~ ∞ Ω.When the resistance value of resistor 106 is set to 0 Ω, the detection voltage Vdet1 that current sense input 50 detects is the current potential of the second lead-out terminal 16d.The electric current flowing through light source module 100 is determined by the voltage produced at the two ends of the resistor 51 being equipped on ignition device 10a.Therefore, when the resistance value of resistor 106 is 0 Ω, there is maximum current in light source module 100 supply.
On the other hand, when the resistance value of resistor 106 is set to ∞ Ω, the second lead-out terminal 16d is open circuit.Electric current towards light source module 100 flows through secondary path Ps.That is, the electric current of light source module 100 flows through in the path of anode → node the 103 → three splicing ear 105c, 15c → current sense input 50 → resistor 71 → resistor 51 of first lead-out terminal 16c → the first splicing ear 15a, 105a → light source 102.In such cases, the electric current flowing through light source 102 is determined by being equipped on the resistance value (2 resistance values and) of the series resistance of the resistor 51,71 of ignition device 10a.
