Abstract
The technical problem to be solved in the invention is to provide a high-power reflection-type LED (light emitting diode) daytime driving lamp which comprises a driving lamp bottom shell, a lampshade, a circuit board equipped with LED lamp beads, an electric connection line and reflective bowls. The daytime lamp at least adopts five 1W LED lamp beads, the at least five reflective bowls are integrated into a whole, the reflective bowls are paratactic semi-paraboloids by side view, an opening penetrating through LED lamp beads is arranged at the bottom of each reflective bowl, and the reflective bowls are at least five paratactic rectangles by front view, the inner reflective surface of each reflective bowl is a frosted surface; the reflective bowls use multiple reflectors for light distribution, the lamp beads are arranged at the bottom of the reflective bowls, the reflective bowls are semi-parabolas with the focal length of 0.5 cm by side view, the inner reflective surface of each reflective bowl is processed with 8*7 reflective surfaces, thus direct light of the lamp beads can be avoided; and meanwhile, the frosted reflective surfaces cannot generate directional diffuse reflection, so that the reflected light can be more gentle and glare stimulation on passersby and traveling vehicles can be avoided.
Description
Technical field
The present invention relates to a kind of automobile lamp, relate in particular to a kind of high power reflective LED daytime running lamps.
Background technology
At present, daytime running lamps also do not use on the automobile at home, the expert call that the area of only a few is also only arranged in the world, should on the vehicle that travels, use daytime running lamps, especially the expert of European Union thinks, automobile, truck and big bus car are equipped with to drive a vehicle in the daytime and can allow them more showy, help traffic safety, reduce traffic accident, and require energy-conservation.Also drafting the corresponding regulations standard in the world.EU Committee announces that European Union rose due to 2012 and carries out an automobile new standard, requires the vehicle of new listing to be equipped with daytime running lamps.
At the car light that uses in the daytime, need high brightness in advance, promptly need powerful car light, what existing car light was used is the requirement that common halogen tengsten lamp can satisfy power, but the life-span of halogen tengsten lamp is short, and the energy consumption height does not meet environmental requirement.Along with the maturation of great power LED technology, be many times of halogen tengsten lamp the service life of LED, and with under the constant power, the LED lamp is tens times of halogen tengsten lamp, and the technology that the great power LED technology is used for daytime running lamps exists may.
Summary of the invention
The technical problem to be solved in the present invention provides and a kind ofly can realize environmental protection requirement when realizing high brightness in the high power reflective LED driving lamp of using in the daytime.
The present invention is by following scheme technical solution problem, daytime running lamps include car light drain pan, lampshade, the wiring board that LED lamp pearl is housed, electrical interconnection, reflector, its described lamp in the daytime adopts 5 1WLED lamp pearls at least, described at least 5 reflectors are one, the side-looking of reflector is a half paraboloid arranged side by side, the opening that passes LED lamp pearl is arranged at the bottom, just is being considered as 5 rectangles arranged side by side at least.The interior table reflective surface of described reflector is a frosting.Reflector adopts multipath reflection body luminous intensity distribution, the lamp pearl is in the reflector bottom, 5.0 centimetres of semi-parabolics of focal length, reflective surface is processed into 8 * 7 reflectings surface in the reflector, avoid the direct projection of lamp pearl like this, reflective surface adopts frosting simultaneously, improves the non-directional diffuse reflection, make the light of reflection softer, avoid the high light of passerby and driving is stimulated.Play lamp prompting function on daytime, avoid light pollution simultaneously.
As further improvement, described LED lamp pearl is 5.
As further improvement, described LED lamp pearl power is 1W.
This invention is compared with original technology, has following advantage:
The present invention adopts large-power LED light bead, and promptly the lamp pearl of 1W power is compared with common halogen tengsten lamp, and under same brightness, the consumption of electric energy is the 1/10-1/2 of common Halogen lamp LED.And the use of 5 LED lamp, can effectively realize together the contrast of light in the daytime.
Reflector structure of the present invention is compared with original circular reflector, change has taken place in reflective form, light has increased the contrast of light when penetrating at last and the light of the reflector reflection that the light that penetrates in each reflector is circular for another example is light independently one by one, and is more eye-catching.
The present invention carries out frosted by the interior table reflective surface with reflector and handles, and by the repeatedly non-directional reflection of light at the reflector inner surface, light is compared with original reflector, and light is softer, has prevented to dazzle the eyes the generation of phenomenon.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention done the following specifically describes:
Fig. 1 splits structure chart for daytime running lamps; Fig. 4 and shown in Figure 5 is seen on car light back cover 4 bases; described car light back cover has by the lead at the bottom of the back cover 7; the weaving webmaster 6 of guardwire; the sealing ring that is used for the sealed bottom hole; be used for female mouth 9 with the fixing 3P of car body; heat-shrink tube 8; the public pin of H13 and be positioned at car light back cover 4 O-ring seal suitable for reading; fixing glue that is used for fixing and silica gel; the LED lamp pearl of 5 1W is installed on Fig. 3 circuit board 3; lead 7 is connected with circuit board; circuit board is fixed on the car light drain pan by screw; 5 reflectors 2 are processed into one; the cross section of each reflector is a semi-parabolic; parabolical focal length is 5.0 centimetres; reflective surface has been processed into 8 * 7 reflectings surface in the reflector; see shown in the accompanying drawing 2; the reflector bottom opening is opposed 1 LED lamp pearl respectively; the interior table reflective surface of reflector is processed into frosting, and outermost is seen with lampshade 1 sealing and formed daytime running lamps by Fig. 6.
This patent is this a kind of form of the specific embodiment not only, is the protection domain of this patent with the similar mode of this patent.Reflector can adopt the various materials that can be suitable for.The shape of reflector can be different with the shape of patent figures indication, such as be greater than or less than 8 * 7 reflectings surface at the change and the reflecting surface of parabolic focal length, is the protection domain of this patent as long as can realize function that this patent is explained.
