Abstract
A light distribution structure of a reflector of a car daytime/nighttime running light is characterized in that a plurality of zigzag structures are formed on the inner wall surface of the ring-shaped reflector, the peaks and the troughs of the zigzag structures are arc-shaped and extend in the axial direction of the reflector, and the zigzag structures at the four corners of the inner wall surface are larger than the zigzag structures on the edges. Therefore, when a light source at the bottom of the reflector emits lights, the light rays can be more efficiently reflected and refracted through the zigzag structures.
Description
Technical field
The utility model relates to a kind of Reflecting shade structure of automobile night running in the daytime lamp that improves luminous intensity distribution efficiency.
Background technology
Automobile daytime running lamp is a kind of signal lamp of automatically opening immediately in the time of car engine.This Deng Ju An Installed is at body forward structure, when vehicle is travelled by day, improve significantly other road users to automobile can See degree, increase road safety.Early stage automobile night running in daytime lamp is for meeting standard-required, mostly adopt halogen bulb, but along with scientific and technological progress, now designed automobile night running in daytime lamp system adopts the LED light source of high brightness, can significantly reduce the electric energy needing, increase life-span of battery, and LED light source MaLS more reaches 10000 hours, be almost equal to the service life of vehicle; But automobile night running in daytime lamp is had relatively high expectations for luminous intensity distribution performance, General Requirements center luminous intensity must not be lower than 400cd, and not higher than 800cd; Just do not reach prompting function lower than 400cd, the sight line that can affect other drivers in subtend track higher than 800cd, is prone to accidents.
While using high-power LED, conventionally to see through medium element (lens or reflection shield) its luminous energy is done to reasonable distribution and utilization, can it also reach the indispensable factor of country and international standard for the luminous intensity distribution performance of automobile night running in daytime lamp, therefore high efficiency light distribution structure is also the urgently problem of Decision to be separated of LED automobile night running in daytime lamp.
summary of the invention
The purpose of this utility model, shortcoming that luminous intensity distribution hot spot that system provides one effectively to overcome known automobile night running in daytime lamp is inhomogeneous, the design cycle is long, the efficiency of light energy utilization is low, size restrictions is large etc., has that hot spot is even, the design cycle is short, the reflection shield light distribution structure of efficiency of light energy utilization high and provide a kind of.
The technical solution of the utility model is: the internal diameter wall that ties up to the reflection shield of ring-type forms plural zigzag structure, the crest of described zigzag structure and trough are curved shape and extending axially at reflection shield, by this, while being located at the light source luminescent of reflection shield bottom, utilizing those zigzag structures to be able to anti-She ﹑ more expeditiously and reflect light.
A feature more of the present utility model, four corners settings that tie up to reflection shield internal diameter wall are large zigzag structure with respect to other each limits, make light be able to become good reflection compensation in those corner regions.
The utility model has the advantages that: in the time being located at the light source luminescent of reflection shield bottom, utilized those zigzag structures more expeditiously anti-She ﹑ reflect light.

Fig. 2 is the embodiment floor map of the Reflecting shade structure of demonstration the utility model.
Fig. 3 is the profile along the A-A ' direction of Fig. 2, shows the schematic diagram of the reflection shield reflection ray of the utility model simultaneously.
Detailed description of the invention
Below coordinate graphic and component symbol to do the more explanation of detail to embodiment of the present utility model, studying carefully after this description and can implement according to this in order to do making to have the knack of this skill person.
As shown in Figures 1 and 2, the Reflecting shade structure that the utility model provides, this reflection shield 1 has the interior space 10 of extending a degree of depth, and the internal diameter wall in this interior space 10 is reflective surface 101, and the bottom in interior space 10 provides at least one light source 2 (as shown in the 3rd figure) is set; At embodiment of the present utility model, be to adopt light-emittingdiode (LED) as light source.The preferred embodiment of described reflective surface 101 be to be formed as when face is watched before, having plural zigzag structure 11 from reflection shield 1, and the size of this zigzag structure 11 is larger with respect to other positions in four corners of reflection shield 1 internal diameter wall; In addition, the crest 111 of described zigzag structure 11 is curved shape and extending axially at reflection shield 1 with trough 112.
As shown in Figure 3, by aforesaid Reflecting shade structure, when being located at the light source 2 of reflection shield 1 bottom center when luminous, part light can directly project reflection shield, part light can be projected to reflective surface 101, and then utilizes those zigzag structures 11 by light reflection and reflect reflection shield 1; Wherein, light can become good reflection compensation by the zigzag structure reflection compared with thick and refraction in each corner regions of reflection shield 1, and then becomes more high efficiency luminous intensity distribution.
The utility model system adopts following methods manufacture to produce the reflection shield light distribution structure with aforementioned advantages: (1) LED light source is selected: select from LED light source lighting angle, colour temperature, light distribution, forward voltage.(2) analytical standard: distribute and calculate corresponding Illumination Distribution figure according to the luminous intensity distribution of standard reflection shield, the hot spot scope of generation is cut and is divided into n homalographic grid, then calculate the luminous flux of unit grids area.(3) according to the size of actual reflection shield, the luminous flux of light source is divided into three parts: direct projection utilizes Qu ﹑ direct projection can not utilize Qu ﹑ reflection to utilize district, cutting sub reflector utilizes district's luminous flux and direct projection to utilize the sum total luminous flux in district, corresponding Target ellipse hot spot unit are luminous flux.(4) set up light-ray equation and energy equation according to catadioptric law, be converted into Mathematical Modeling.(5) in order to obtain attractive in appearance and light mixing effect, smooth surface set reflection shield is cut and is divided into multiple curved surfaces, i.e. the zigzag structure of the utility model, the editing machine of recycling computer software is write formula, solves a series of multiple surface coordinates point.(6) coordinate points is imported to drawing software, point is connected into close-shaped; By point, to line, line is to face, and face is to entity, thus reduced model.(7) model is imported to suitable computer optics software and carry out optical analog checking.(8) result of verifying in optics software is output model as met the requirement of design,, as having deviation with designing requirement, repeat above-mentioned (2)-(7) Bu Sudden, until meet the requirements.
As described above is only in order to explain the preferred embodiment of the utility model; not attempt tool the utility model is done to any formal restriction; be with; all any modification or changes that has the relevant the utility model of doing under identical utility model spirit, all must be included in the category of the utility model intention protection.
