Description

A kind of greeting lamp with dynamic projection function

Technical field

The utility model 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.

Utility model content

To solve the above problem existing for currently marketed greeting lamp, the utility model provides a kind of with dynamic projection The greeting lamp of function and uniform optical distribution.

To achieve the above object, the utility model 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 utility model uses polycrystalline integrated LED, it is possible to reduce the size of lamps and lanterns.

2. the utility model is suitable for various vehicles, uniform optical distribution, pattern intensity height.

3. Intelligent Dynamic drop shadow effect may be implemented in the utility model.

Specific embodiment

The present invention will be further described with reference to the accompanying drawings and examples.

The utility model proposes a kind of greeting lamps with dynamic projection function, as shown in Figure 1, mainly including LED light source The components such as module 2, collector lens 3, Turbogrid plates 4, film 5 and projecting lens 6, LED light source module 2 include at least two LED 7, when work, when the LED 7 in LED light source module 2 is in " bright " state, the light issued is corresponding by LED 7 Collector lens 3 obtains multi beam converged light, first passes through Turbogrid plates 4, then pass through the effect of film 5, every beam light all carries each From pattern-information, and view field I, view field II, view field III are projected to by corresponding projecting lens 6 and is thrown Shadow zone domain IV obtains required light type pattern, wherein all corresponding collector lens 3 of every LED 7 and a projecting lens 6, All collector lenses 3 and projecting lens 6 all can directly be processed into an entirety, more convenient for assembling.

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.

Limitation to scope of protection of the utility model, those skilled in the art should understand that, in the skill of the utility model On the basis of art scheme, the various modifications or variations that can be made by those skilled in the art with little creative work still exists Within the protection scope of the utility model.
