A projection lamp 100 according to an embodiment of the first aspect of the present invention is described below with reference to fig. 1-3.
The projection lamp 100 according to an embodiment of the present invention includes: a plurality of projection units and a control module.
In particular, each projection unit comprises at least one projection module 1. For example, each projection unit may include one projection module 1, or may include a plurality of projection modules 1, where a plurality means two or more.
The projection module 1 is adapted to project a first target image, where the first target image may be a static pattern, and when each projection unit includes a plurality of projection modules 1, all the projection modules 1 in each projection unit are adapted to project according to a preset program so as to combine all the first target images into a second target image, where the second target image may be an animation or a static pattern. When each projection unit has only one projection module 1, the second target image is the same as the first target image and is a static pattern. Optionally, the second target image projected by each projection unit is different. In this way, the projection lamp 100 can project different animation or static patterns as required, for example, when the vehicle is switched to a different state, the projection lamp 100 can be switched to a different second target image. The control module may control execution of the preset program in response to a preset control instruction, where the preset control instruction may correspond to state information of the vehicle.
For example, when the automobile is in an acceleration state and the second target image to be projected is a running person, the corresponding projection unit may include two projection modules 1, where the first target image projected by one projection module 1 is a person pattern with a front left foot and a rear right arm, and the first target image projected by the other projection module 1 is a person pattern with a front right foot and a rear left arm, and at this time, the control instruction may be that the two projection modules 1 project alternately, and then the control module controls the projection unit to operate according to the control instruction, that is, the projection unit may be caused to project a running person pattern.
When the vehicle is in a welcome state and the second target image to be projected is a person who is welcomed to bend over, the corresponding projection unit may include one projection module 1, the first target image projected by the projection module 1 is the person who is welcomed to bend over, at this time, the control instruction may be to control the projection module 1 to work and continue for a preset time, and then the control module controls the projection unit to work according to the control instruction, so that the projection unit can project the person who is welcomed to bend over within a certain time. Optionally, when there are character elements such as "welcome ride" or other elements on the second target image, the corresponding projection module 1 may be added.
According to the projection lamp 100 provided by the embodiment of the invention, a plurality of projection units are arranged, and each projection unit comprises at least one projection module 1, so that the projection lamp 100 can control the corresponding projection unit to work according to different running states of the vehicle, and the projection units can project static patterns or animation according to different projection modules 1, thereby being beneficial to enhancing the technological sense of the vehicle and improving the user experience.

In this way, the light emitted from the light emitting element 11 passes through the condenser lens assembly 13, the film assembly 14 and the imaging lens assembly in sequence to project the first target image.
According to some embodiments of the present invention, each projection unit can be independently controlled, so that a plurality of projection units can work simultaneously, independently, or in any combination, thereby diversifying the target image projected by the projection lamp 100 and providing more scientific and aesthetic feeling.
Further, the projection modules 1 corresponding to each projection unit can be independently controlled, for example, when one projection unit includes a plurality of projection modules 1, the plurality of projection modules 1 can work simultaneously or according to a preset time sequence, so as to project a static or dynamic effect.
According to some embodiments of the present invention, backsheet assembly 14 may comprise: an imaging plate 141 and a fixing support 142. The imaging negative film 141 is provided with a pattern to be projected, the pattern on the imaging negative film 141 can be formed by engraving the light shielding plate, for example, the imaging negative film 141 can be a film, the imaging negative film 141 is detachably arranged on the fixing support 142, and the fixing support 142 is detachably arranged in the shell 12, so that the structure is simple, the assembly and disassembly are convenient, the film can be replaced, and the pattern projected by the related projection module 1 can be changed.
According to some embodiments of the present invention, codes may be provided for the imaging negatives 141 of all projection modules 1 of all projection units and stored in the control module. After the second target image needing to be projected is determined according to the current state of the vehicle, the control module firstly determines the code of the imaging negative film 141 of the projection module 1 needing to start working according to the current state of the vehicle, and after the pattern on the imaging negative film 141 is obtained according to the code, the pattern is sent to a vehicle owner, the vehicle owner confirms whether the pattern is in accordance with the second target image, for example, the pattern is sent to a central control display screen of the vehicle for the vehicle owner to confirm, and after the vehicle owner confirms, the control module controls the corresponding projection module 1 to work, so that the projected second target image can be prevented from being not matched with the current state of the vehicle, the projection accuracy is improved, and the user experience is improved.

Further, controlling the projection unit to operate includes: and controlling at least one projection module 1 corresponding to the projection unit to project according to a preset program. For example, when the automobile is in an acceleration state and the second target image to be projected is a running person, the corresponding projection unit may include two projection modules 1, where the first target image projected by one projection module 1 is a person pattern with a front left foot and a rear right arm, and the first target image projected by the other projection module 1 is a person pattern with a front right foot and a rear left arm, and then the control module controls the two projection modules 1 of the projection unit to alternately project according to a preset time period, so that the projection unit may project the running person pattern.
Optionally, a unique number corresponding to the first target image may be configured for the imaging negative film 141 of each projection module 1 of the projection unit, so that during the projection process of the projection unit, the control module may automatically read the number, obtain the corresponding first target image according to the number, send the first target image to the vehicle owner for confirmation, determine the vehicle state bound by the number according to the confirmation information of the vehicle owner, and then automatically project the corresponding static pattern or animation.
According to some embodiments of the present invention, the turn-on time may also be preset for projection lamp 100. For example, in general, the light is sufficient in the daytime, and the pattern projected by the projection lamp 100 is not too obvious, so the turn-on time of the projection lamp 100 can be set to be at night, and of course, the specific time of the sun falling into the mountain is different in different seasons and different regions, so the preset turn-on time can be determined according to the factors such as the seasons and the regions.
In some other embodiments, before acquiring the current state of the vehicle, the current light intensity of the external environment may be acquired, and when the current light intensity of the external environment is lower than a preset value, the projection lamp 100 may be turned on, so that it may be ensured that the second target image projected by the projection lamp 100 is sufficiently obvious.
