What are the external contacts and internal contacts of high pressure sodium lamps?
If the circuit lighting ballast or lamp ballast + + + trigger, can reach the requirements of the normal work of the high-pressure sodium lamp trigger high-pressure sodium lamp ignition circuit.
In the working circuit of high pressure sodium lamp, in addition to the bulb, it must also trigger the high pressure sodium lamp or trigger the high pressure sodium lamp, and select the corresponding working circuit respectively,
The circuit of the matching work is different.In the work of the circuit in addition to high pressure sodium lamp bulb, also must press the trigger high-pressure sodium lamp or external trigger high-pressure sodium lamp were used to work the corresponding circuit, such as light bulbs or lamp ballast circuit + + + ballast can trigger, ignition circuit to seek external trigger high-pressure sodium lamp high pressure sodium lamp to work properly.
