Description
Technical field
The present invention relates to a kind of automobile head light, be specifically related to a kind of LED headlamp that is suitable for vehicle (like motorcycle, automobile, electric motor car) usefulness.
Background technology
LED (light emitting diode) be described as the 4th generation light source, it has the advantage that the life-span is long, light efficiency is high, radiationless.The theoretical life-span of LED surpasses 100,000 hours, and luminous efficiency is up to 90%, and the energy consumption of same light flux is merely 8% of incandescent lamp, has the advantage of significant green, low-carbon (LC).Worldwide LED is used widely in lighting field.
It is light source that present automobile head light mainly adopts incandescent mercerising lamp, Halogen lamp LED.Because the light efficiency of incandescent mercerising lamp and halogen light source is low, caloric value is big, the life-span is short; The utilization rate of light is low; So there is very big potential safety hazard in the problem that existing automobile head light ubiquity illumination is weak, caloric value is big, the life-span is short (being prone to blow, be prone to fragmentation like filament).
Because the extensive use of LED and the remarkable advantage that is had thereof; Many people attempt to adopt LED as automobile head light; But because the structural design of LED headlamp is reasonable inadequately, light utilization efficiency is not high, light decay serious, heat radiation is bad, can not be arrived in the appointed area of filament shield by the light of reflector reflection; Desirable distance light hot spot or dipped beam hot spot can't be formed, the light distribution requirements of country can not be reached about automobile head light; Therefore, fail to be widely used.
Summary of the invention
The purpose of this invention is to provide a kind of automobile-used LED headlamp, this headlamp can improve the emergent light brightness of light source, forms the hot spot of high brightness, to reach the light distribution requirements of country about automobile head light.
Automobile-used LED headlamp of the present invention comprises LED lamp pearl, reflector, slide and back cover, and LED lamp pearl is positioned at reflector, and LED lamp pearl and reflector are installed in the back cover, and slide is arranged on reflector the rim of a bowl the place ahead; The reflecting surface of said reflector is to be the benchmark curved surface with the parabola, and the centre of luminescence of said LED lamp pearl is positioned on the focus of benchmark curved surface.LED lamp pearl is adopted once the lamp pearl of light envelope moulding, and reflector is the hollow body that adopts metal or plastic shaping, adopts the vacuum film to improve the reflecting effect of reflecting surface on the reflecting surface of reflector.The reflecting surface of reflector (being inner surface) is a free form surface; This free form surface is to be the benchmark curved surface with the parabola; This parabola is divided into several zones; Adjust each regional curvature and direction, the light that LED is sent is mapped to each zone back light of reflecting surface and is reflected to formation high brightness hot spot in the appointed area of filament shield, and these each regional curved surfaces are promptly formed free form surface.
Said headlamp is a dipped headlights; The LED lamp pearl centre of luminescence is arranged on the focus of said benchmark curved surface; The rim of a bowl with reflector is forward a benchmark, and the direction that is provided with of LED lamp pearl is that light-emitting area makes progress, or on the basis that light-emitting area makes progress, tilts 0 °～60 ° forward or backward; The light that LED lamp pearl sends is all or part of to be dropped in the first half reflecting surface of reflector, and the light that LED lamp pearl sends is through reflecting surface reflection formation forward "cut-off"line clearly.
Said headlamp is a high beam; The LED lamp pearl centre of luminescence is arranged on the focus of benchmark curved surface; The rim of a bowl with reflector is forward a benchmark, and the direction that is provided with of LED lamp pearl is that light-emitting area is downward, or on luminous prone basis, tilts forward or backward 0 °～90 °; The light that LED lamp pearl sends in reflecting surface reflexes to the zone of the place ahead filament shield appointment, tilt forward or backward 90 ° to be lamp pearl light-emitting area be right against reflector the rim of a bowl direction or be right against the reflector bowl at the bottom of direction.
Said headlamp is the Assembled lamp of distance light and dipped beam, is forward benchmark with the rim of a bowl of reflector, with the reflecting surface of reflector to be divided into two parts up and down perpendicular to the rim of a bowl; The first half is the dipped beam reflecting surface; The latter half is the distance light reflecting surface, the first half dipped beam reflecting surface of reflector, and it is to be the free form surface that the benchmark curved surface forms after adjusting with a parabola; LED lamp pearl is set on the focus of this benchmark curved surface; And guarantee that the LED lamp pearl centre of luminescence drops on the focus of this benchmark curved surface, the direction that is provided with of LED lamp pearl is that light-emitting area makes progress, or on the basis that light-emitting area makes progress, tilts 0 °～60 ° forward or backward; Be that the light that LED lamp pearl sends is through reflecting surface reflection formation forward "cut-off"line clearly in all or part of the first half reflecting surface that drops on reflector of the light that sends of LED lamp pearl; The latter half distance light reflecting surface of said reflector; It is to be the free form surface that the benchmark curved surface forms after adjusting with another parabola; Other LED lamp pearl is set on the focus of this benchmark curved surface; And guarantee that the LED lamp pearl centre of luminescence drops on the focus of this benchmark curved surface, the direction that is provided with of LED lamp pearl is that light-emitting area is downward, or on luminous prone basis, tilts forward or backward 0 °～90 °; The light that LED lamp pearl sends in reflecting surface reflexes to the zone of the place ahead filament shield appointment, tilt forward or backward 90 ° to be lamp pearl light-emitting area be right against reflector the rim of a bowl direction or be right against the reflector bowl at the bottom of direction.The characteristics of this combination head lamp are that the light that LED lamp pearl sends can only be through being positioned at the dipped beam reflecting surface reflection of the first half; Obtain "cut-off"line clearly; The light that LED lamp pearl sends mainly through the reflection of distance light reflecting surface, also can pass through the beam split of dipped beam reflecting surface reflecting part.
In order better to control the light decay of LED; Accelerate heat radiation; Behind reflector bottom centre installing hole, be provided with electronic refrigerating chip and radiator, electronic refrigerating chip adopts existing ripe product, and its basic structure comprises the electronics P-N knot at middle part and the heat-absorbent surface and the heating face of upper and lower surfaces; LED lamp pearl directly or indirectly is attached on the heat-absorbent surface of electronic refrigerating chip, and the heating face of electronic refrigerating chip is close on the radiator.
The present invention is placed on the LED lamp pearl centre of luminescence on the focus of benchmark curved surface; And select the different directions that is provided with according to different headlamp; Make the light that sends from LED lamp pearl be reflected to the appointed area on the filament shield; Formed the distance light hot spot or the dipped beam hot spot of high brightness, reached the light distribution requirements of country, thereby realized the application of LED headlamp in motorcycle, automobile, electric motor car about automobile head light.
