Abstract
The utility model discloses an efficient LED automobile dipped beam headlamp. An LED light source is fixed on a radiator; a lens is disposed before the LED light source and is fixed on a lining frame; a reflecting mirror is disposed between the radiator and the lens and is above the LED light source; a baffle plate is fixed below the reflecting mirror; the reflecting mirror comprises a first main reflecting mirror capable of casting ray to the lens and a first auxiliary reflecting mirror capable of casting ray to a position below a portion between the baffle plate and the lining frame; the baffle plate is fixedly provided with a reflecting plate reflecting blocked ray to the lens for a second time; and the bottom of the baffle plate is connected with a second reflecting mirror reflecting reflected ray of the first auxiliary reflecting mirror to a position ahead of the bottom of the lens for a second time. The reflecting plate reflects the blocked ray to the lens and thus acquires a dipped beam light type having a cut-off line, thereby improving utilization rate of light quantity, improving grading effect greatly, and increasing lighting distance and width obviously. The first auxiliary reflecting mirror and the second reflecting mirror are combined to reflect the ray on the front end of the reflecting mirror to the position ahead of the bottom of the lens for a second time, thereby enhancing lighting brightness and forming III area illumination.
Description
Technical field
The utility model shines the high a kind of high efficiency LED automobile lower beam headlamp of dipped beam led light source, particularly led light source utilization rate before relating to automobile.
Background technology
Existing LED automobile lower beam headlamp uses projector structure mostly; As shining dipped headlights before the disclosed a kind of automobile of Chinese utility model patent (CN201561349U); Its luminescence unit and radiator are superimposed; Each luminescence unit is made up of reflector 7, baffle plate 5, lens 2 and light source 10; Its operation principle is: reflector 7 converges the light that led light source 10 sends, and shelters from part light to form "cut-off"line through baffle plate 5, and light obtains having the dipped beam type of "cut-off"line again after lens 2 converge; The shortcoming that this lower beam headlamp exists mainly contains: 1. light is by baffle plate 5 eclipsing losses, and the utilization rate of the light that led light source 10 sends is lower, and promptly the utilization rate of luminous flux of light source is lower; 2. the light that reflecting surface reflected of reflector 7 far-ends; Reflex to which direction light angle that 2 refractions are penetrated through lens all more than 12 °; And this part light is mapped to apart from light fixture 3.5m with interior scope apart from ground level 0.75m calculating (0.75/tan12 °=3.5) recent photograph by light fixture; And this part light has no meaning in driving, so this part light also belongs to waste.Therefore the irradiation distance of the light of this lower beam headlamp is nearer, the light width is narrower, light light is darker.
The utility model content
For solving before the above-mentioned automobile according to the existing problem of dipped headlights, the utility model is intended to propose a kind of high efficiency LED automobile lower beam headlamp, makes the distance of irradiate light of light farther, width increases, brightness is higher.
For reaching above-mentioned purpose; The utility model proposes a kind of high efficiency LED automobile lower beam headlamp; Comprise radiator, be fixed on led light source, lens on the radiator and be arranged on led light source the place ahead and be fixed on the lining frame; Speculum is located between radiator and the lens and is positioned at the top of led light source; One baffle plate vertically is fixed on speculum below, it is characterized in that: speculum is by converging light first principal reflection mirror that projects lens and can constitute the first auxilliary arrangement of mirrors that light converges the below that projects between baffle plate and the lining frame; Baffle plate top cross fixing one can secondary reflect to the light that is blocked by baffle plate the reflecting plate of lens; Baffle plate bottom connection one can secondary reflect to the reflection ray of the first auxilliary speculum second speculum in the place ahead, lens bottom.
Described first principal reflection mirror is connected with the first auxilliary mirror integral moulding.
Described baffle plate, reflecting plate and the second mirror integral moulding are connected.
The beneficial effect of the utility model is: 1. the reflecting plate through the baffle plate top secondary reflects to lens to the part light that is blocked by baffle plate; To obtain having the dipped beam type of "cut-off"line; The most of light that filters that is blocked simultaneously is fully used; The utilization rate of luminous flux is improved, and light distribution effect is significantly promoted, and makes the irradiation distance of light, width obviously increase; 2. cooperate through the first auxilliary speculum and second speculum to secondary reflect to the place ahead, lens bottom to the light of speculum front end, the light luminance of enhancing light also forms the illumination in III district.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The operation principle sketch map that Fig. 2 has the dipped beam type of "cut-off"line for the utility model acquisition.
Fig. 3 obtains to have the operation principle sketch map of the big dipped beam type of illumination width for the utility model.
