Description of the embodiments

The utility model is further described below with reference to the drawings and specific examples.

1-4, a vehicle door panel integrated with a projection lamp includes a door panel body 200 and a projection lamp 100; the outer surface of the door panel main body 200 is provided with a target projection area and a protruding part higher than the target projection area, and the surface shape of the target projection area is a free curved surface; the projection lamp 100 is placed in the boss and obliquely projected on the target projection area and forms a projection pattern 300; the target projection area includes a proximal end and a distal end, and a ratio of a distance between the distal end of the target projection area and the projection lamp to a distance between the proximal end of the target projection area and the projection lamp is greater than 2.5.

The vehicle door panel of the embodiment integrates the projection lamp 100, and the projection pattern 300 can be formed in the target projection area on the door panel main body 200 through the projection lamp 100, so that compared with the existing surface-emitting vehicle door panel, the vehicle door panel has no need of changing the internal structure of the vehicle door panel, and the structural design is simplified; meanwhile, the projection lamp 100 can be suitable for various vehicle door panels with different surface shapes of the target projection area, the surface shape change can achieve the pattern required by final vision only by changing the imaging image 41 on the film, the existing surface-emitting vehicle door panel can not be like the existing surface-emitting vehicle door panel, and the internal structure of the vehicle door panel needs to be changed again along with the surface shape change of the vehicle door panel, so that the cost is reduced as a whole.

The degree of blurring of the projection pattern 300 is affected by various factors such as the focal length, the inclination angle, and the distance from the surface to be projected of the projection lamp 100, and when the inclination angle between the optical axis and the surface to be projected is made larger in the case where the vertical distance between the projection lamp and the surface to be projected is fixed, the more blurring is made at the far lamp end of the projection pattern 300, because the distance between the far lamp end of the projection pattern 300 and the distance between the near lamp end of the projection pattern 300 are too different, and the focal length required at the far lamp end of the projection pattern 300 is different from the focal length required at the near lamp end of the projection pattern 300, and the projection lamp of the conventional structure cannot make the far lamp end and the near lamp end of the projection pattern 300 clear at the same time. Since the projection lamp 100 is installed on the vehicle door panel 200 in this embodiment, the installation position determines that the projection lamp 100 is very close to the vehicle door panel 200, so that the projection pattern 300 with a larger size needs to be formed by tilting the target projection area projected on the vehicle door panel 200, but when the ratio of the distance between the distal end of the target projection area and the projection lamp 100 to the distance between the proximal end of the target projection area and the projection lamp 100 is greater than 2.5 times, this also means that the width dimension of the projection pattern 300 is larger, and finally the distal end of the projection pattern 300 is blurred. While conventional other off-board projection lights on vehicles, such as floor lights, logo welcome lights, tend to be less than a factor of 2.

In order to make the far-end of the projection pattern 300 clearer, the projection lamp in this embodiment includes an LED lamp 20, a condenser lens module 30, a film 40 and an imaging lens module 50, which are disposed on the circuit board 10, and the light generated by the LED lamp 20 sequentially passes through the condenser lens module 30, the film 40 and the imaging lens module 50 and is projected to the target projection area to form the projection pattern 300; the projected pattern 300 includes a near light end and a far light end; the film 40 is inclined with respect to the optical axis direction, and the film 40 has an imaging pattern 41, and the unit imaging pattern on the imaging pattern 41 corresponds to the unit projection pattern on the projection pattern, and the unit projection pattern corresponding to the unit imaging pattern closer to the LED lamp 20 is closer to the lamp near end. In this embodiment, the film 40 in the projection lamp 100 is disposed obliquely to the optical axis direction, so that the back intercept of the unit imaging pattern on the film 40 increases with the distance between the corresponding unit projection pattern and the projection lamp 100, thereby making the projection pattern 300 at the far lamp end clearer. In this embodiment, the entire film 40 is black and can block light, and the imaging pattern 41 is formed by a light-permeable region of the film 40.

It should be appreciated that in an actual vehicle door panel product, there may not be a distinct line of distinction between the target projection area on the door panel body 200 and other areas, and if there is no line of distinction, the location occupied by the projection pattern 300 may be considered as the target projection area.

In this embodiment, the condensing lens module 30 includes a first condensing lens 31 and a second condensing lens 32, the divergence angle of the led lamp 20 is 120 °, the divergence angle of the light after the condensing effect of the first condensing lens 31 is 60 °, the divergence angle of the light after the condensing effect of the second condensing lens 32 is 24 °, and then the light enters the film 40.

In another embodiment, the condensing lens module 30 may also achieve a predetermined condensing effect using a single condensing lens, but the single condensing lens needs to increase the size in terms of length and width or diameter of the condensing lens due to a large angle of deflecting light. The use of two condenser lenses increases the size in the thickness direction relative to a single condenser lens, and thus the particular use of a single condenser lens or two condenser lenses may be determined based on practical space constraints for the projection lamp 100.

The imaging lens module 50 in this embodiment includes a first collecting lens 511, a second collecting lens 512 and a first dispersing lens 531, wherein the first collecting lens 511 is used for collecting the light passing through the film 40 and deflecting the collected light, the second collecting lens 512 is used for further deflecting the collected light, and the first dispersing lens 531 is used for emitting the collected light and controlling the focal length of the projection lamp 100. Considering that the vehicle door panel 200 is closer to the projection lamp 100 and the projection pattern 300 has a larger width, adding a specially designed wide-angle diverging lens 532, i.e., a second diverging lens, can project a relatively larger field angle, thereby covering the entire target projection area while reducing system distortion.

If the projection lamp 100 is a white light source, color difference occurs in the projection lamp because the white light is actually composed of RGB three-color light, and the refractive indexes of the light rays with different colors or wavelengths in the glass or other material lens are different, when the mixed light passing through the unit imaging pattern on the film 40 passes through the imaging lens module 50 again, the corresponding unit projection pattern has chromatic aberration (color difference for short) caused by the light path difference of the different color light due to the refractive indexes, and the naked eye looks like a smear phenomenon. The larger the angle of inclination of the projection lamp 100, the more severe the smear at the far lamp end of the projection pattern 300. To solve this problem, in the present embodiment, the imaging lens module 50 further includes an acromatic lens 52, where the acromatic lens 52 is a combined lens formed by bonding flint glass and crown glass, and the acromatic lens 52 can effectively solve or reduce the chromatic aberration problem.

The light passing through the imaging pattern 41 is projected to the target projection area through the imaging lens module 50 to form the projection pattern 300, but it is required to know that the material of the lens is not 100% pure, and very little impurity exists, although the impurity is very few, a small amount of light passing through the imaging lens module may deviate from a preset propagation route, which finally results in the situation that the projection pattern 300 is out of stray light, and the situation is more serious as the number of lenses in the imaging lens module 50 is more. In order to solve the flare problem, in the present embodiment, a stop member 60 is further disposed in front of the first diverging lens 531, and the stop member 60 can block the light passing through the imaging lens module 50 at a final projection position outside the range of the projection pattern 300, in other words, the stop member only allows the light passing through the imaging lens module 50 at a final projection position within the range of the projection pattern 300, and the projection pattern 300 is finally formed by the light.

While the utility model has been described with reference to a preferred embodiment, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present utility model as defined by the following claims.
