Abstract

Disclosed is a tilt angle type high-low dimmer HID xenon lamp with high reliability and random connection of an anode and a cathode and without permanent magnet part and polar operation. An insulated shell and an anti-dazzling screen are fixed on a metal disc of a headlight of an automobile, in the surrounding of the insulated shell, a round hole of a heel piece is aligned with a round hole of a coil skeleton, an iron core penetrates through the coil skeleton and the heel piece and is coaxially inlaid and combined therewith, an HID lamp tube, a lamp holder and an armature are sequentially inlaid and connected with one another, the armature is hung on the heel piece end, a sideline on the heel piece end is taken as a shaft, the lamp holder can smoothly slide, rotate and swing by a certain angle by taking the shaft as a pivot, a spring is disposed at the top end of the armature and at the top end of one side of the heel piece parallel to the armature, the lamp holder can upwards swing to a limiting point integrated with the coil holder to be in a low lamp state under the pulling action of the spring, when the coil is injected with direct current, the coil generates a magnetic field to magnetize the iron core, then the armature attracts the iron core under the action of electromagnetic attraction, so as to drive a lamp holder mechanism to move to a level position to form a high lamp state. The on and off of the coil current realize high-low lamp dimming.

Description

Swing angle type just becomes light HID xenon lamp

Affiliated technical field

The utility model relates to a kind of swing angle type conversion height lamp device of DC control, does not especially have permanent magnetism part and nonpolarity operation, and the swing angle type that both positive and negative polarity arbitrarily connects just becomes light HID xenon lamp.

Background technology

At present, known change light HID auto lamp internal structure is made up of ring flange, the U-shaped yoke of HID fluorescent tube, lamp socket, coil rack, solenoid, permanent-magnet steel, iron core, guide rail copper sheathing, band guide rail bearing.When to forward or backwards pulse voltage of one of solenoid input, iron core slides towards the high end of magnetic induction intensity, after the dead electricity because the effect of permanent-magnet steel, iron core is subjected on the magnetic maintenance position at one end, the forward and reverse iron core that just makes that switches the pulse voltage of solenoid input produces reciprocal rectilinear motion, thereby makes the result who forms the conversion of height lamp with lamp socket, the HID fluorescent tube of iron core machinery matching relationship.But the iron core motion will overcome the active force of permanent-magnet steel, needs the outside that opposite, the high magnetic induction intensity active force of direction is arranged, and is exactly that solenoid needs big input current.The generation of big electric current, positive and negative pulse voltage causes the complexity of control circuit, also has the permanent-magnet steel characteristic that magnetic lost efficacy when operating temperature surpasses Curie temperature, and working environment influences the reliability of its work all than higher temperatures just.

Summary of the invention

In order to improve the reliability of work, the utility model provides a kind of swing angle type just to become light HID xenon lamp, this swing angle type just becomes light HID xenon lamp device and removes permanent magnetic part, change the power supply mode of solenoid: by both positive and negative polarity connect must be correctly, pulse power supply control forward or backwards transfers the control that nonpolarity operation, both positive and negative polarity arbitrarily connect to, simplify control circuit, thereby improved the reliability of work.

The technical scheme that its technical problem that solves the utility model adopts is: insulation crust and anti-dazzling screen are fixed on the automobile front metal dish, in the encirclement of insulation crust, skeleton around coil, yoke, iron core, armature, spring, parts such as lamp socket are by the marriage relation assembling, circular hole on the yoke aligns with the coil rack circular hole, iron core passes coil rack, the yoke circular hole is coaxial inlays combination, the lead rear section glass that HID fluorescent tube metal leg connects silicone rubber insulation layer inserts lamp socket, fix with the silicone adhesive embedding, the residue glass part extends in outside the insulation crust, lamp socket and armature are spliced and are suspended on the yoke end, with the sideline on the yoke end is axle, lamp socket is that fulcrum can be along sliding rotary oscillation certain angle with the axle, spring is equipped with on the top of armature top and yoke one side parallel with armature, because the pulling force effect of spring, lamp socket can swing upwards into the spacing point of coil holder one and end, two power conductor that connect the HID fluorescent tube pass from insulation crust rear end via hole with the control line that is connected solenoid, put the insulation wire bushing, crimp connector is to electric power system.This utility model mainly is to utilize electromagnetic induction principle work, when coil passes to DC current, coil just produces magnetic field, iron core in the middle of the coil generation magnetic force that is magnetized, thereby armature is inhaled to iron core under the effect of electromagnetic attraction, this moment, armature drove the lamp socket mechanism kinematic to becoming level with ground, made the HID lamp tube light source in high lamp source position, formed high light by the effect of automobile headlamp catoptric system and shone; When disconnecting the electric current of coil, iron core just loses magnetism, armature restPoses under the pulling force effect that spring recovers, armature drive this moment lamp socket mechanism kinematic to spacing point ends, HID fluorescent tube and ground form an angle, the HID lamp tube light source is displaced to low lamp position, forms low light by the effect of automobile headlamp catoptric system and shines.Above operation principle as can be seen, as long as provide enough DC voltages, electric current to coil, no matter the sense of current how, coil just produces magnetic field and drives the lamp socket mechanism action, the conversion of realization from low lamp to high lamp, and transform to low lamp from high lamp, and be to finish by the active force that recovers spring, electric current need not be provided.
