5.
Visually bulb checking (no filament): damaged glass, damaged for upper parts and lower parts of glass tube.
Elements
Xenon gas: Xenon gas activates the initial reaction for rapid illuminating.
Molybdenum electrode: anode arcing
Metal halide salts: color composing component
Lightening principle
When Xenon gas and metal halide salt will discharge the molybdenum anode in a capsule, it emits light.
Ignitor is an electromagnetic transformer that receives current from ballast and boost voltage to light on the arc light source in any environment.
Ballast delivers an instant high voltage pulse to the ignitor electrode, to initialize discharge in the source.
Ballast supplys the stable power to the bulb and the ignitor during initialization and normal state of arc.
Durable for vibration as there is no filament.
HID lamp had a more long life than halogen lamp.
Does not operate if polarity are changed.
Operating input voltage : 9-16V
Check the battery voltage. (Low beam will be on when the battery voltage above 9V.)
Check the fuse and relay.
Check the polarity of ballast. (If the polarity are changed, low beam doesn't lighten)
Check the bulb connector securely.
Visually bulb checking (no filament): damaged glass, damaged for upper parts and lower parts of glass tube.
After 1~5, replace the ballast and the ignitor (ballast assembly).
No. | Item | Service procedures | Warning | Remarks |
1 | Replacement of lamp assembly | 1. Turn the head lamp switch off 2. Disconnect the power connector from the lamp 3. Remove and replace the lamp assembly 4. Connect the power connector 5. Installation is the reverse of removal | ● Turn the head lamp switch off to avoid high voltage | ● Other description is the same as the halogen bulbs |
2 | Replacement of the Bulb | 1. Turn the head lamp switch off 2. Disconnect the power connector from the lamp 3. Remove the lamp assembly 4. Remove the ballast 5. Remove the dust cover 6. Remove the bulb socket and replace the bulb 7. Installation is the reverse of removal | ● Turn the head lamp switch off to avoid high voltage ● Be careful not to damage the bulb and use genuine bulbs only ● Do not apply excessive force and fit it correctly. ● Confirm the bulb locking | |
3 | Replacement of the Ballast (with built-in ignitor) | 1. Turn the head lamp switch off 2. Disconnect the power connector from the lamp 3. Remove the head lamp assembly 4. Remove the ballast 5. Remove the dust cover 6. Disconnect the bulb socket from the bulb 7. Replace the ballast 8. Installation is the reverse of removal | ● Turn the head lamp switch off to avoid high voltage | ● Replace the ballast only and install the used lamp ● Replace the sub assembly except the ballast |
4 | Others | 1. Power supply should be according to the rated capacity 2. Use the rated fuse and wire 3. Bulb socket shall be free from moisture or dirt. 4. Do not apply the ballast severe shock, water, or extreme heat | ● All parts should be serviced only at specified service centers. | ● HID lamp should not be installed on other cars (Dangerous, fire may occur) |
HID lamp shall not be used on other cars.(Fire may occur.)
Fire may occur when HID lamp initially lights due to the fact that arc-discharge generates high voltage (max. 20,000V) and high current(12-13A), and are different from the halogen lamp specification.
Install the dust cover after confirming the locking state between bulb and bulb holder.
When testing the HID head lamp, turn the power on or off with switch between power supply and lamp because of high voltage.
Do not operate the head lamp switch with the bulb not installed, because it generates spark momently.
