Description

Welcome lamp with dynamic projection function
Technical Field
The invention relates to the field of automobile lamps, in particular to a welcome lamp with a dynamic projection function.
Background
At present, people have more and more functional demands on car lights, except for necessary lamps such as far and near lights, fog lights, brake lights and the like, more and more lamps for decorating or creating atmosphere are arranged on the car, and the welcome lamp is one of the lamps, and is popular because a certain light spot pattern can be projected when the lamp gets on or off the car, and noble atmosphere is created.
The mode of the projection pattern of the welcome lamp on the current market mainly can be divided into two modes, the first mode is to utilize the principle that the film and the projection lens group project the optical pattern, the scheme is simple in structure, low in cost and relatively mature in technical process, but the uniformity of the projection pattern is not high, and as a plurality of lenses exist in the whole lamp, the optical efficiency is low, and the dynamic projection effect cannot be realized during projection; the other is to use the principle of fly-eye lens and image array imaging, the proposal condenses the light emitted by the light source through a single condensing lens, then projects the light-emitting type at a certain distance through the fly-eye lens and the image array, the light-emitting type LED light source has the advantages of good uniformity of the projected pattern and high light efficiency, but the light of each LED is distributed on the whole pattern, the light efficiency is improved, and the dynamic projection effect cannot be realized.
Disclosure of Invention
In order to solve the problems of the welcome lamp in the current market, the invention provides a welcome lamp with dynamic projection function and uniform optical distribution.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
the utility model provides a usher's lamp with dynamic projection function, it includes drive control module, LED light source module, condenser lens, film and projection lens set gradually along the light direction that the LED sent, LED light source module contains two at least LEDs, the LED sends out light, the light gathers through corresponding condenser lens, the light carries required pattern information under the effect of film, go out through corresponding projection lens projection, splice and form required light type; the drive control module controls the on-off state of each LED individually.
Further, a grid plate is arranged between the condensing lens and the film, the grid plate comprises a grid array, the grid array corresponds to the LEDs one by one, and mutual crosstalk of optical channels is prevented.
Further, the condensing lenses are in one-to-one correspondence with the LEDs, i.e. there is a separate condensing lens for each LED.
Further, all the condensing lenses are integrally formed, so that the assembly is more convenient.
Further, the film has a plurality of sub-patterns, and part of the sub-patterns are different.
Further, each LED in the LED light source module at least corresponds to one sub-pattern on the film.
Further, the projection lenses are in one-to-one correspondence with the sub-patterns on the film, i.e., each projection lens corresponds to a sub-image.
Further, all projection lenses are integrally formed, so that the assembly is more convenient.
The beneficial effects are that:
1. The invention adopts the polycrystal integrated LED, and can reduce the size of the lamp.
2. The invention is suitable for various vehicles, has uniform optical distribution and high pattern brightness.
3. The invention can realize intelligent dynamic projection effect.

FIG. 2 is a schematic diagram of the LED drive control of the present invention;
FIG. 3 is a schematic view of a film according to the present invention;
FIG. 4 is a schematic view of a grid plate of the present invention;
In the figure: the LED light source comprises a 1-driving control module, a 2-LED light source module, a 3-condensing lens, a 4-grid plate, a 5-film, a 6-projection lens, 7-LEDs, an I-projection area I, an II-projection area II, an III-projection area III and an IV-projection area IV.
Detailed Description
The invention will be further described with reference to the drawings and examples.
The invention provides a welcome lamp with a dynamic projection function, as shown in fig. 1, the welcome lamp mainly comprises an LED light source module 2, a condenser lens 3, a grid plate 4, a film 5, a projection lens 6 and other components, wherein the LED light source module 2 at least comprises two LEDs 7, when the LEDs 7 in the LED light source module 2 are in a bright state in operation, light emitted by the LEDs passes through the condenser lenses 3 corresponding to the LEDs 7 respectively to obtain a plurality of converging lights, the converging lights firstly pass through the grid plate 4 and then pass through the film 5, each beam of light carries respective pattern information and is projected to a projection area I, a projection area II, a projection area III and a projection area IV through the corresponding projection lens 6 respectively to obtain a required light pattern, each LED 7 corresponds to one condenser lens 3 and one projection lens 6, and all the condenser lenses 3 and the projection lenses 6 can be directly processed into a whole, so that the welcome lamp is more convenient to assemble.
As shown in fig. 2, the LDO (low dropout linear regulator) model in the driving control module 1 is TLE4250G of inflight, the MCU (microprocessor) is a MC9S12G series of feishar, which sends and transmits data in a CAN communication manner, and has multiple output ports and error reporting functions, when the LED function fails, error reporting information CAN be fed back, which CAN individually control the on and off states of each LED 7 in the LED light source module 2, and because the sub-patterns corresponding to part of LEDs 7 on the film 5 are different, when each LED 7 in the LED light source module 2 is controlled to be turned on according to a certain rule or sequence, the finally projected pattern CAN present a dynamic effect.
As shown in fig. 3, the film 5 includes a plurality of sub-patterns, and part of the sub-patterns are different, and each LED 7 in the LED light source module 2 corresponds to at least one sub-pattern on the film 5.
As shown in fig. 4, the grid plate 4 includes a grid array, and the grid array is in one-to-one correspondence with the LEDs 7, so as to prevent crosstalk of optical channels.
