HID LAMP WITH SEPARATE IGNITION ASSEMBLY {HID LAMP WITH AN ASSEMBLY OF IGNITER SEPARABLE FROM BULB}

The present invention relates to a HID lamp having a detachable igniter assembly for easily converting a D2 type bulb into a D1 type bulb or a D4 type bulb into a D3 type bulb.

More specifically, the present invention is to make it easy to use the D1 type or D3 type bulbs used in the headlights of the automotive field, aviation field, etc., and easily compatible with the D2 type or D4 type bulbs currently widely used. HID lamp is configured to separate only igniter assembly from D1 type bulb or D3 type bulb.

Currently, high-density discharge lamps (HID lamps) are used in light bulbs mainly used in headlights of automobiles and aircrafts. The D2 type HID bulb, which is a standard bulb, not only has excellent lifespan and power efficiency compared to halogen lamps, but also secures a user's visible area with sufficient light quantity.

However, since these HID bulbs require a high starting voltage of more than 25,000 volts and a corresponding control circuit necessary to induce discharge, the resulting electromagnetic field may cause mutual interference to the advanced control device of the vehicle. .

In order to overcome these technical difficulties, one of the ignition devices, the ballast has used a HID bulb mounted directly to the bulb igniting circuit (igniting circuit) necessary for starting. As such, the HID lamp in which the bulb and the ignition device (Igniter) are integrated is called a D1-type bulb.

As such, with the advent of the D1 type bulb, it has no influence on the various precision control devices mounted on the vehicle. In particular, it is possible to extend the life of the bulb with the minimum starting voltage, and is designed excessively against the vibration of the vehicle. The voltage can be reduced from 25,000 volts to 20,000 volts. In recent years, according to the recognition that eco-friendly products are applied to vehicles, the demand is gradually increasing along with the production of D3 bulbs without adding mercury in the bulb.

For the reasons described above, the user has no choice but to use only D1-type or D3-type bulbs in which the bulb and the igniter (Igniter) are integrated. Accordingly, even when the ignition device is intact, in order to replace the old bulb, the only option is to purchase and replace a high-priced D1 bulb in which the ignition device is integrated, which increases the cost of replacement or repair. In addition, the replacement of a good igniter (igniter) all at once is a source of national resource waste.

The present invention aims to solve the problems of the prior art described above, and in general, anyone can easily attach or detach a standard D2 type light bulb or a D4 type light bulb to an ignition device that can be easily purchased at a low price. It is an object of the present invention to propose a HID lamp having a separate igniter assembly that allows a standard D2 type bulb to be shared with a D1 type bulb and a standard D4 type bulb to be shared with a D3 type bulb.

In order to achieve the above object, the present invention is characterized in that the standard D2 bulb or D4 bulb is configured as a detachable igniter assembly that can be detached or mounted to the igniter assembly.

As described in the present invention, the user has two contact terminals 117 and 148 electrically contacting the D2 or D4 bulb base 131 to the circuit board 110 provided therein through the opening 139 of the igniter assembly. It is provided, characterized in that the configuration that can be assembled or detached to the D2 or D4 bulb ignition assembly.

When using a D1 or D3 bulb consisting of the separate ignition assembly of the present invention, when the bulb is replaced, such as old or damaged, instead of replacing the entire expensive D1 bulb or the entire D3 bulb, a standard D2 bulb is commercially available. Alternatively, replacing only the D4 bulb can achieve the same effect as replacing the D1 bulb or the D3 bulb, and thus, various advantages that can not be obtained in the D1 bulb or the D3 bulb of the existing technology, such as cost saving and ease of maintenance, can be obtained. have.

The components of the present invention shown through the drawings may be represented in various other forms, and thus the following detailed description should not be considered as limiting the claims of the present invention, and is understood only as a representative example of a preferred embodiment of the present invention at this point in time. I will have to.

For reference, the meaning of each term used in the description of the present invention is as follows.

"D2 bulb" means a HID standard bulb consisting of a light tube and a base.

"D4 bulb" means a mercury free HID standard bulb. The D4 bulb also consists of a light emitting tube and a base only.

“D1 bulb” refers to an assembly in which the HID standard light emitting tube is integrally coupled with an igniter (igniter).

"D3 bulb" means an assembly in which a mercury free HID standard light emitting tube is integrally combined with an igniter.
