According to the LED light source head lamp, the defects in the prior art can be overcome, the different LED lamps controlled by the single-pole three-throw switch are designed, the installation positions of the LED lamps are reasonably designed, different lighting levels are adjusted, and lighting dead zones are reduced.
Description
Technical field
The present invention relates to a kind of light fixture, especially a kind of LED light source headlamp.
Background technology
The light source of car headlamp uses halogen bulb more at present, as H4 bulb.The luminous volume of halogen bulb is large, and the life-span is short, and the efficiency of light energy utilization is low.Light emitting diode (Light-Emitting Diode, LED), as new type light source, has luminous efficiency high, long service life, and reliability high, has been widely used in various illuminating products at present.Along with the continuous maturation of LED technology and the reduction of cost, become possibility as car headlamp with LED, therefore LED be also referred to as the 4th generation vehicle lamp light source.Adopt the car headlamp of conventional light source, because the cause of conventional light source causes the efficiency of light energy utilization generally on the low side, wanting increases the efficiency of light energy utilization by reflector, but reflector bore is larger, and Hyundai Motor front portion is lower and adopt airflow design, thereby it is less to leave the bore of car headlamp for.Therefore, how exigence at car headlamp bore hour, obtains the maximum efficiency of light energy utilization.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of LED light source headlamp, can improve the deficiencies in the prior art, the different LED lamp by design by the control of SP3T switch, and the installation site of appropriate design LED lamp, realize the adjusting of different brightness of illuminations, reduced lighting blind zone.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of LED light source headlamp, comprise lamp body, the edge of described lamp body is provided with several LED lamps, the one LED lamp is divided into ten arc LED lamp bands and is uniformly distributed as the center of circle taking the center of described lamp body, the radius of curvature of arc LED lamp band is 2: 1 with the ratio of the interior radius of a circle of arc LED lamp band composition, the angle of the inner circle of arc LED lamp band and its composition is 20 °, there is the 2nd LED lamp of annular in the arranged outside of each LED lamp, the power of the 2nd LED lamp is greater than the power of a LED lamp, inner side at arc LED lamp band is provided with the 3rd LED lamp, the 3rd LED lamp is taking the center of described lamp body as circle is uniformly distributed, the arranged outside of the 3rd LED lamp has the 4th LED lamp of annular, the power of the 4th LED lamp is greater than the power of the 3rd LED lamp, the arranged outside of the 3rd LED lamp and the 4th LED lamp has diffuser, and the transparent wavelength range of diffuser is 550nm～650nm, also comprise a SP3T switch, first loop of SP3T switch is in series with a LED lamp, and second loop of SP3T switch is in series with the 3rd LED lamp, and the 3rd loop of SP3T switch is in series with the 2nd LED lamp and the 4th LED lamp.
As preferably, in the fluorescent tube of a described LED lamp, the 2nd LED lamp, the 3rd LED lamp and the 4th LED lamp, be provided with cylindrical metal cover, an electrode short circuit in cylindrical metal cover and fluorescent tube.
As preferably, the fluorescent tube afterbody of a described LED lamp, the 2nd LED lamp, the 3rd LED lamp and the 4th LED lamp is provided with radiating fin.
The installation site of the present invention's the one LED lamp and arrangement mode can reduce by 60% lighting blind zone, and the diffuser in the 3rd LED lamp outside only sees through gold-tinted and ruddiness, can build the photoenvironment of dim warmth, and light is not dazzling.In the time of needs highlight illumination, SP3T switch is adjusted to tertiary circuit, high-power the 2nd LED lamp and the 4th LED lamp are lighted simultaneously, so that enough illumination to be provided.High pressure, high temperature and electric spark that when cylindrical metal cover can shield fluorescent tube startup on the one hand, between electrode and electrode, moment produces; Play on the other hand the rapid effect to electrode and filament cooling, reduced the probability that filament is blown.Radiating fin can be strengthened the radiating effect in the use procedure of LED lamp.
