Description
Technical field
The present invention relates to car lights field, especially a kind of greeting lamp with dynamic projection function.
Background technique
Currently, people are more and more for the functional requirement of car light, in addition to long-and-short distant light, fog lamp, Brake lamp etc. are necessary
Lamps and lanterns have the lamp that will be installed some decorations or construction atmosphere on more and more vehicles, and greeting lamp is exactly one of which, because it is upper
It can be projected out certain spot pattern when getting off, build honorable atmosphere and very popular.
Currently marketed greeting lamp can be divided mainly into two kinds according to the mode of its projection pattern, the first is to utilize the film
Piece and projection microscope group are projected out the principle of optical design, and such scenario-frame is simple, and cost is relatively low, technical matters relative maturity,
But the uniformity of its projection pattern is not high, since, there are multi-disc lens, optical efficiency is low in entire lamps and lanterns, and can not when projection
Realize dynamic projection effect；Another kind is the principle being imaged using fly's-eye lens and pattern matrix, and such scheme issues light source
Light carry out optically focused by single collector lens, using fly's-eye lens and pattern matrix, project light-emitting type in a certain distance,
Its advantage is projection pattern good evenness, and light efficiency is high, but its by the light distribution of each LED on entire pattern, improve light
Effect, but cannot achieve dynamic projection effect.
Summary of the invention
To solve the above problem existing for currently marketed greeting lamp, the present invention, which provides one kind, has the function of dynamic projection
And the greeting lamp of uniform optical distribution.
To achieve the above object, the present invention adopts the following technical solutions:
A kind of greeting lamp with dynamic projection function, it include drive control module, LED light source module, collector lens,
Film and projecting lens, the radiation direction that LED light source module, collector lens, film and projecting lens are issued along LED is successively
Setting, LED light source module include at least two LED, and LED emits beam, and converge light by corresponding collector lens, light exists
Required pattern-information is carried under the action of film, is projected away by corresponding projecting lens, and institute's light-dependent type is spliced to form；
Drive control module individually controls the light on and off state of every LED.
Further, it is provided with Turbogrid plates between collector lens and film, includes grid array on Turbogrid plates, and grid
Lattice array and LED are corresponded, and prevent the mutual crosstalk of optical channel.
Further, collector lens and LED are corresponded, i.e., all there is individual collector lens therewith for every LED
It is corresponding.
Further, all collector lenses are integrally formed, more convenient for assembling.
Further, there are multiple sub-patterns, and partial subgraph case is not identical on film.
Further, every LED in LED light source module at least corresponds to a sub-pattern on film.
Further, the sub-pattern on projecting lens and film corresponds, i.e., each projecting lens corresponds to one
A subgraph.
Further, all projecting lens are integrally formed, more convenient for assembling.
The utility model has the advantages that
1. the present invention uses polycrystalline integrated LED, it is possible to reduce the size of lamps and lanterns.
2. the present invention is suitable for various vehicles, uniform optical distribution, pattern intensity height.
3. Intelligent Dynamic drop shadow effect may be implemented in the present invention.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
The present invention proposes a kind of greeting lamp with dynamic projection function, as shown in Figure 1, mainly including LED light source module
2, the components such as collector lens 3, Turbogrid plates 4, film 5 and projecting lens 6, LED light source module 2 include at least two LED 7, work
When making, when the LED 7 in LED light source module 2 is in " bright " state, the light issued passes through the corresponding optically focused of LED 7
Lens 3 obtain multi beam converged light, first pass through Turbogrid plates 4, then pass through the effect of film 5, and every beam light all carries respective figure
Case information, and view field I, view field II, view field III and projected area are projected to by corresponding projecting lens 6
Domain IV obtains required light type pattern, wherein all corresponding collector lens 3 of every LED 7 and a projecting lens 6, own
Collector lens 3 and projecting lens 6 all can directly be processed into an entirety, for assemble it is more convenient.
As shown in Fig. 2, LDO (low pressure difference linear voltage regulator) model Infineon in drive control module 1
TLE4250G, MCU (microprocessor) are the MC9S12G series of Freescale, are sent by CAN communication mode and transmit number
According to, have the function of the output port of multichannel and report an error, when there is LED function failure, error information can be fed back, it can be independent
" bright " and " going out " state of each LED 7 in LED light source module 2 is controlled, and since part LED 7 is right on film 5
The sub-pattern answered is different, when controlling each LED 7 in LED light source module 2 according to certain rules or when sequential illumination, finally projects
To pattern can show dynamic effect.
As shown in figure 3, including multiple sub-patterns in film 5, and partial subgraph case is not identical, and in LED light source module 2
Every LED 7 all at least correspond to a sub-pattern on film 5.
As shown in figure 4, including grid array on Turbogrid plates 4, and grid array and LED 7 are corresponded, and prevent optical channel
Mutual crosstalk.
Limiting the scope of the invention, those skilled in the art should understand that, in technical solution of the present invention
On the basis of, the various modifications or variations that can be made by those skilled in the art with little creative work still of the invention
Within protection scope.
