DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0029] Example 1

[0030] like Figures 1 to 7 As shown, the utility model provides a stripe projection lamp, comprising a projection plane 1 and a light-emitting mechanism 2 obliquely arranged at the rear side of the projection plane 1; the light-emitting mechanism 2 comprises a circuit board 21 and a projection control block 22 arranged at the front side of the circuit board 21; a plurality of light beam channels 23 are sequentially opened on the projection control block 22, a plurality of LED lamp beads 24 are arranged at the front end of the circuit board 21, the plurality of LED lamp beads 24 are arranged in one-to-one correspondence with the plurality of light beam channels 23, and the light emitted by each of the LED lamp beads 24 is projected onto the projection plane 1 through the corresponding light beam channel 23; at least some of the plurality of light beam channels 23 have different sizes, and at least some of the light beam channels 23 are not parallel to each other.

[0031] In actual use, since the light emitted by each LED lamp bead 24 needs to be projected onto the projection plane 1 through the corresponding beam channel 23, stripe light is formed on the projection plane 1; when the width of the beam channel 23 is larger, the stripe light projected onto the projection plane 1 is wider, and when the height of the beam channel 23 is larger, the stripe light projected onto the projection plane 1 is longer; when the beam channels 23 are not parallel to each other, that is, the inclination angles of the beam channels 23 relative to the central axis L extending in the front-to-back direction of the projection control block 22 are different, the stripe light projected onto the projection plane 1 is also not parallel to each other. Therefore, by setting each beam channel 23 to have different widths, different heights and / or different inclination angles relative to the central axis L of the projection control block 22, stripe light with different widths, different lengths and / or different inclination angles is presented on the projection plane.

[0032] In this embodiment, by controlling the size of each light beam channel 23 in the projection control block 22, that is, controlling the width and length of each light beam channel 23, and controlling the mutual parallelism between each light beam channel 23, that is, controlling the inclination angle of each light beam channel 23 relative to the central axis L extending in the front-to-back direction of the projection control block 22, it is possible to achieve stripe lights of different widths, different lengths and / or different inclination angles on the projection surface; in this embodiment, the diversity of the stripe projection lamp can be achieved through a simple structure.

[0033] Further, see Appendix Figure 7 Each of the LED lamp beads 24 is provided with an IC chip 25 and three light-emitting modules 26 , wherein the three light-emitting modules 26 are a red light-emitting module 261 , a blue light-emitting module 262 and a green light-emitting module 263 , and the three light-emitting modules 26 are arranged in sequence along the vertical direction.

[0034] In this embodiment, the specific arrangement order of the three light-emitting modules 26 is not limited. For example, the red light-emitting module 261, the blue light-emitting module 262 and the green light-emitting module 263 can be arranged in sequence from top to bottom, or the blue light-emitting module 262, the red light-emitting module 261 and the green light-emitting module 263 can be arranged in sequence from top to bottom, or the green light-emitting module 263, the blue light-emitting module 262 and the red light-emitting module 261 can be arranged in sequence from top to bottom, and so on. In this embodiment, since the three light-emitting modules 26 are arranged in sequence along the vertical direction, and the light-emitting mechanism 2 is tilted on the rear side of the projection plane 1, that is, the circuit board 21 and the projection control block 22 are tilted on the rear side of the projection plane 1, the three light-emitting modules 26 form strip lights of different colors and different lengths in the projection plane 1; when a single light-emitting module 26 is lit, strip lights of corresponding colors will appear; when more than two light-emitting modules 26 are lit, more than two strip lights of different colors will appear partially overlapping, and the overlapping part of the strip lights will show colors other than red, blue, and green. For example, when red light and green light overlap, yellow light will appear, and when red light and blue light overlap, purple light will appear, and so on, thereby increasing the diversity of the colors of the strip lights. The IC chip 25 inside each LED lamp bead 24 dynamically controls the specific lighting states of the red light-emitting module 261, the blue light-emitting module 262 and the green light-emitting module 263 in the LED lamp bead 24, that is, dynamically controls whether they are on or off. The stripe light projected by the stripe projection lamp can dynamically change in length and color. At the same time, the control effect of the light beam channel 23 is superimposed, so that the stripe light size, inclination angle and color of the stripe projection lamp presented on the projection plane 1 can be dynamically changed, making the change of the stripe projection lamp more diversified, and the overall structure of the stripe projection lamp is simple and the cost is low.

[0035] Furthermore, it also includes a base 3, which includes a projection seat 31 and a mounting seat 32 obliquely arranged on the rear side of the projection seat 31, the upper surface of the projection seat 31 is the projection plane 1, and the light-emitting mechanism 2 is installed on the upper surface of the mounting seat 32; preferably, a first angle α is formed between the upper surface of the projection seat 31 and the upper surface of the mounting seat 32, and the first angle α is an obtuse angle.

[0036] In this embodiment, by specifically configuring the base 3 as a projection base 31 and a mounting base 32, and the mounting base 32 being tilted at the rear side of the projection base 31, when the light-emitting mechanism 2 is mounted on the upper surface of the mounting base 32, the circuit board 21 and the projection control block 22 are mounted on the upper surface of the mounting base 32, and the circuit board 21 and the projection control block 22 can be tilted relative to the projection plane 1, so that the structure is simple, compact and has good effect.

[0037] Furthermore, the light-emitting mechanism 2 also includes a protective cover 27, and the protective cover 27 is arranged on the outside of the circuit board 21 and the projection control block 22. In this embodiment, the circuit board 21 and the projection control block 22 are protected by the protective cover 27 to prevent external dust, impurities, etc. from entering the circuit board 21 and the projection control block 22, thereby affecting their use effect and service life. Specifically, the protective cover 27 is in a rectangular shape and has an opening on the bottom surface, so that the protective cover 27 is conveniently arranged on the outside of the circuit board 21 and the projection control block 22, and the side of the protective cover 27 opposite to the projection control block 22 is also set to an opening shape, so that the light coming out of the beam channel 23 is directly projected onto the projection plane 1; the protective cover 27 is specifically made of a light-shielding material to prevent the light emitted by the LED lamp beads 24 from penetrating from other positions, thereby affecting the effect of the entire stripe projection lamp.

[0038] Further, the plurality of beam channels 23 are parallel to the same plane, and the cross section of the beam channel 23 is rectangular. Specifically, the plurality of beam channels 23 are parallel to the upper surface or the lower surface of the projection control block 22 .

[0039] Furthermore, if Figure 6 As shown, the central axis L extending along the front-to-back direction of the projection control block 22 and each of the light beam channels 23 respectively form a second angle β, and at least some of the light beam channels 23 have different second angles β; specifically, the second angle β is an acute angle. In this embodiment, by specifically limiting the size of the second angle β of each light beam channel 23, that is, limiting the size of the inclination angle of each light beam channel 23 relative to the central axis L extending along the front-to-back direction of the projection control block 22, the inclination angle of the stripe light presented on the projection plane 1 is controlled.

[0040] Furthermore, the magnitude of the second angle β of the plurality of light beam channels 23 increases from the middle light beam channel 23 to the light beam channels 23 on both sides. Figure 1 As shown, in this embodiment, by setting the second angle β, the strip light on the projection plane 1 presents a fan shape.

[0041] Example 2

[0042] The utility model also provides a car, which comprises the stripe projection lamp described in any one of the first embodiments.

[0043] In the present embodiment, a stripe projection lamp is arranged in the automobile. The stripe projection lamp has not only a simple structure, but also can simultaneously control the specific light emitting states of the three light emitting modules 26 in each LED lamp bead 24 through each IC chip 25, so that the color, size and inclination angle of the strip light presented by the automobile's atmosphere lamp can be changed at the same time, and each IC chip 25 controls each LED lamp bead 24 to light up in sequence, so that the strip light presented by the automobile's atmosphere lamp can achieve a flowing water effect while changing the color, size and inclination angle, thereby increasing the diversity of the dynamic changes of the automobile atmosphere lamp, meeting the needs of different consumers, and being conducive to improving the luxury and grade of the automobile interior.

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model.
