Abstract
The utility model relates to a dipped headlight of an automobile headlight, by using LED as a light source. Three units are stacked and combined with a heat radiator to realize enough flux quantity and the light type required by the dipped headlight. Each unit consists of a multi-ellipsoidal reflective surface, a baffle plate and a light source. The light source is a multiple-chip linear packaged large-power LED, the reflective surface is a multi-ellipsoidal reflective surface, and a lens is an aspherical lens.
Description
Technical field
The utility model relates to a kind of car headlamp dipped headlights, as light source, adopts many ellipsoids reflecting surface, baffle plate, lens to carry out the optics and the frame for movement of luminous intensity distribution with multi-chip high power LED.
Background technology
Present auto lamp light source mostly is Halogen lamp LED or high-voltage gas discharging light, and the light efficiency of led light source improves greatly in recent years, because it has the perfect light source that advantages such as the speed of lighting is fast, energy-conservation, long-life become auto lamp of future generation.Because the characteristics of luminescence of LED necessarily requires light fixture to have good heat-sinking capability, and can not occupy excessive space, therefore also will guarantee sufficiently high light extraction efficiency simultaneously, that can satisfy light distribution requirements when designing good heat dissipation, efficient height, good reliability again becomes the technological difficulties of LED car headlamp with LED as the dipped headlights of light source.
Summary of the invention
In order to overcome the difficulty that existing automobile lamp can not directly replace with light source led light source, the utility model provides a kind of dipped headlights structure, this structure adopts great power LED as light source, and many ellipsoids reflector, baffle plate, lens constitute optical texture and form dipped beam light type.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of car headlamp dipped headlights, comprise three unit that are superimposed and radiator, and it is characterized in that each unit by reflector, baffle plate, lens and light source are formed.3 identical optical unit stacks provide enough luminous fluxes.The reflector of each unit is many ellipsoids reflector, and reflecting surface is free form surface, and lens are non-spherical lens, and light source adopts the encapsulation of multicore sheet straight line.Many ellipsoids reflector converges the light that high-power LED light source sends, and shelters from part light to form "cut-off"line through baffle plate, and light obtains dipped headlights institute light-dependent type again after lens converge.Radiator leaves the usefulness of cavity for heat pipe heat radiation.All there is heat dissipation base each unit, to guarantee the requirement of LED to temperature.The led light source position is near many ellipsoids reflector first focus.Non-spherical lens is positioned near many ellipsoids reflecting surface second focus.
The beneficial effects of the utility model are, have realized the light distribution requirements of dipped headlights can satisfying the requirement of LED to heat radiation simultaneously again with led light source, have improved lamp life and efficient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a mechanical construction drawing of the present utility model
Fig. 2 is an optical schematic diagram of the present utility model
The accompanying drawing mark
1 lining frame, 2 non-spherical lenses, 3 back-up rings, 4 M4 screws, 5 baffle plates, 6 M3 screws, the reflector of ellipsoid more than 7,
