HID, High Intensity Discharge is a gas discharge at high temperatures and pressure that leads to high light output. As Xenon is used as main filling gas, this light has also been named xenon light in automotive applications. The discharge process is initiated by a very high voltage pulse and transferred into a continous arcing. The starting process and the control of the arc are handled by a ballast. |

Nucon Xenon bulb ballasts |
|
A ballast generates alternating high voltage taken from the cars battery supply. The light output is regulated constantly independing from the battery voltage. |
|
Igniter connector: The ignition coil device shall be placed as close as possible to the bulb to avoid EMI problems. The optimal solution is the combination of connector and igniter ! |

The discharge bulb has two electrode wires inside a small elliptical shaped burner volume. An ignition coil generates a flashover between the electrodes to start discharge. The first automotive discharge bulb was the D1. The improved D2S has its burner inside a glas tube for protection. It also has a high voltage connector socket. The U1 bulb was specially edited for an US company with an insulated outer elektrode to reduce the danger of electric shock. The further improved D1S now uses a socket integrated ignition coil for the high voltage pulse generation (The slitted toroidal coil is shown in the x-ray picture on the right). Each discharge bulb requires a ballst of its own, even with the ignition coil being integrated in the socket. Our nucon ballast is directly connected to the D1S bulb. In order to run a D2S bulb an ignitor modul can be put between the ballast and the D2S using a high voltage connector. |
|
D2S H4 bulb version with direct connected compact igniter unit. The connection cable between igniter and ballast can be made depending to the customer needs quite long that an easy mounting of the ballast inside the vehicle can be achieved where sufficient space is available. Note: in most countries simple upgrading from halogen to HID is not allowed! |
|
21W and 32W HID bulbs ideal for installation in existing small reflectors. The 21W bulb is minimum dimmable down to approx 15W. This bulb has very intresting properties in combination with Nucon ballast like fast flicker free light run up and hot restart capabillity. No outer conductive free touchable electrode important for safety reasons. An ideal bulb for 2 wheel applications like motor cycles or bikes and other portable systems. A smaller Nucon ballast including all safety features will soon be available!!

Left: Brightstar UV bulb. Next bulb is a 24W HID H3 socketed, basically designed for DC bulb current however works fantastic with the new Nucon AC bulb principle which gives more light and more lifetime. Right thereafter you can see two views of the 24W glas reflector type (12° spot) Have a look at a comparisson in between 21W bulb and 24W bulb see also 24W HID bulb halogen comparisson. new hid spotlight comparisson between d1s 35W and 24W brightsstar.

The luminance distribution shows the higher temperature of the arc. |

HID spectral power distribution shows little infra red light and is a continuous spectra. (picture taken from Philps catalog 96) |

|
Why the luminous flux decreases ?
|
|
HID lifetime depends strongly on switching cycles. Overpowering should be avoided by the ballast. (pictures taken from Philps catalog 96) |

Our singular board design enables us to come to real small dimensions, as well as an easy design change for different connector positions on the PCB (The picture on the left shows a longer design version having the connectors at the short side). The good EMI properties of the design do allow the application of an unshielded price reasonable plastic housing. Due to the insulation of the plastic material there are no problems installing the ballast when the car body is connected to one of the battery poles. Not to forget to mention the weight advantage especially for aircraft applications. The molded round version (wattages from 20 to 50W) has a weight just about 220g. |

A volume reduction allone just thin but with a big plane does not grant a good mounting at a vehicle or inside reflectors. On the left you see an example of a new very compact version, designed to be mounted on a frame, for instance of a two wheeler, or to be integrated inside of a tube with a small diameter. |

The complete solution with 67mm outer diameter. It has the standard P32 bajonet plug and will be made available for all wattage ranges 25-50W and as Supersoftstart version. The integrated micro controler board with reed switch enables very easy diving light design. Module is later available only from special OEM customer for this design. |
