Abstract

The present invention relates to a headlamp for a vehicle, and more particularly, a lamp that can serve as a high beam and a low beam as a single lamp.

In the conventional lighting method, there is a disadvantage in that an installation space is required by having a headlamp divided into an upstream and a downward use, and the cost of the installation is increased.

The present invention is to install a trigger electrode 10 for illuminating upward and a light emitting electrode (2) for illuminating downward in one head lamp 20 to solve the above disadvantages of the prior art as a device that combines the high and the low light By giving a so that the front of the car to the installation space of the headlamp 20 is not greatly bound and also to reduce the cost,

As a structure, the trigger electrode 10 is provided in the power supply portion of the molybdenum electrode serving as the light emitting source of the head lamp 20, and the down light roughening electrode 2 is disposed at the downward focus position of the reflector 21 inside the head lamp 20. ) And put the up-lighting trigger electrode 10 spaced apart by a predetermined distance to the up-focusing position to move the focus of the reflection of the light emitting source so that the reflected light is upward or has a function of a downlight. It is a head lamp that doubles up and down to secure the field of vision at night by adjusting the power supply of the light emitting electrode.

Description

Light emitting lamps for automotive headlamps that combine both up and down lights

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head lamp for automobiles, and more particularly, to a lamp that can serve as an uplight and a downlight with a single lamp.

In general, the headlamps are equipped with a separate upper and lower lights on the front of the car, and according to the driver's choice, the driver lights down lights when driving in the city and lights up the lights on roads without long distances or street lights to secure the driver's vision at night. I'm trying to.

The structure of the conventional head lamp 20 will be described. The head lamp 20 includes a lamp 1 having one light emitting electrode 2 emitting light in the center of the inner reflector 21 of the head lamp 20. Is fixed at the focus position set by the direction of the light irradiation direction, connect the luminous power source 3 to it, and attach the high voltage generator 5 to one end thereof to supply the initial luminous power and the voltage regulator to the front terminal. By connecting (4), the light emitting power source 3 supplied to the light emitting electrode 2 is stably supplied.

The general headlamp 20 is manufactured and used for upward or downward fixing by fixing the light emission center of the lamp 1 to the reflection focus according to the downward or upward determination.

In this conventional method, the installation space is required on the front surface of the vehicle by providing headlamps divided into upward and downward directions, thereby limiting the appearance of the vehicle and increasing the cost of the installation. There was this.

The present invention has been made to solve the above conventional problems,

It is manufactured by separating the upward trigger electrode and the downward light emitting electrode in the interior of the lamp 1 installed inside one headlamp 20 and having the functions of upward and downward light by sexually emitting these electrodes. Provided are automotive headlamps.

When described in detail with reference to the accompanying drawings the configuration and operation of the present invention as follows.

2 is a connection diagram of a lamp installed in the headlamp 20 of the present invention, in which a light emitting electrode 2 is provided on one side of a vacuum lamp 1 filled with mercury gas or ion gas, and is separately and predetermined. The trigger electrode 10 is installed to be fixed at a distance apart from each other, and the light emitting electrode 2 is connected to the light emitting power source 3 and is connected to the high voltage generator 5 and at the front of the voltage regulator 4. The trigger 12 is connected in succession. In this trigger 12, the trigger power source 11 connected to the trigger electrode 10 is connected, and the driving switch 6 and the trigger switch 7 at the front end of the trigger 12. ) Is installed.

Referring to the operation of the present invention having the above structure in more detail as follows.

At night, the vehicle is operated by lighting a downlight at an initial stage. At this time, the headlamp 20 is turned on by operating the drive switch 6, which becomes a downlight.

That is, the drive switch 6 passes the trigger 12 and drives the voltage regulator 4 to drive the high voltage generator 5 in the voltage regulator 4 to supply high voltage power to the light emitting electrode 2. By generating a plasma on the light emitting electrode 2 as an initial light emitting power source, a light source is generated.

The state of maintaining the light emission is a state in which the reflector 21 is in the focal position of the headlamp 20 in which the lamp 1 is installed, as shown in FIG. 3. The light emitting electrode 2 is the reflector 21. It is placed in the downward beam position of the to perform the downlight function at all times, and when the driver has a high light function to secure the night vision put more, when the trigger switch 7 is operated, power is supplied to the trigger 12 while trigger power is supplied. Since the power source 11 supplies power to the trigger electrode 10, the trigger electrode 10 also emits light.

The light emitting trigger electrode 10 is spaced apart from the light emitting electrode 2 by a predetermined distance, which is in the upward focusing position as opposed to the downward focusing position, thereby operating the triggering electrode 10. As a result, the headlamp 20 is to be illuminated.

The present invention that acts as described above the front of the car by installing a lamp that can combine both up and down lighting in one headlamp to completely solve the problems caused by installing the upper and lower lights as in the prior art Not only can it be beautiful, it is a very useful invention that can reduce the installation cost of the headlamp.

Claims (1)
