Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a pattern lamp that realizes dynamic projection effects based on high-frequency rotation of a reflector. Background Art

[0002] A pattern light consists of a light source and a pattern disk. The pattern disk has several light holes, each of which is equipped with a pattern translucent sheet. Each pattern translucent sheet is printed with patterns corresponding to different frames in the animation. The light source is fixed in position, and its light beam corresponds to a specific light hole. During operation, the pattern disk rotates at high speed, driving each light hole to pass through the light beam of the light source, thereby projecting a frame of pattern at the projection point. Due to the high rotation speed of the pattern disk, each frame of the pattern at the projection point forms an animation.

[0003] At present, the dynamic pattern lights or dynamic projection lights on the market are mainly divided into two categories according to the number of pattern pieces: single pattern piece and double pattern piece.

[0004] However, both categories have disadvantages:

[0005] As shown in the prior art such as CN 216844531 U and CN 109681834 A, a single-gobo dynamic pattern lamp or dynamic projection lamp uses an intermittent motion mechanical structure to achieve the pause and rotation of the gobo. However, the disadvantages are: (1) the intermittent motion mechanical structure rotates at high speed in a high-temperature lamp body and is prone to jamming; (2) it is difficult to synchronize the high-speed strobing of the light source with the gobo light hole, which easily causes offset; and (3) there is only one gobo, and the output dynamic effect content is very short.

[0006] As shown in the prior art such as CN 111059484 A, a dynamic pattern lamp or dynamic projection lamp with two pattern pieces rotates at high speed without stopping to achieve special effects. However, the disadvantage is that the two pattern pieces overlap without stopping and the specified projection effect content cannot be obtained. Summary of the Invention

In this way, not only can the driving speed of the first driving member 332 and the second driving member 342 and the stroboscopic requirements of the light sources of the first light source unit 31 and the second light source unit 32 be halved, which can better ensure the quality and technical requirements of these components, but it can also double the pattern effect, thereby achieving a longer-lasting dynamic effect, making the pattern light have the advantages of a long service life and good dynamic projection effect for a long time.

[0064] As a further preference, the first connector 353 of this embodiment is sleeved on the driving end of the third driving member 352 .

[0065] In this embodiment, the dynamic projection device 3 also includes an inner shell 37, which is installed inside the outer shell 1 with a gap between the two. A first accommodating cavity is formed inside the inner shell 37, and the first light source unit 31, the second light source unit 32, the first pattern piece unit 33, the second pattern piece unit 34, and the reflecting unit 35 are all installed in the first accommodating cavity; the imaging unit 36 is installed on the outer shell 1.

[0066] Preferably, the inner shell 37 of this embodiment is in the shape of a cube, which can be formed as one piece or enclosed by a plurality of fixing plates or fixing pieces.

[0067] In this embodiment, the reflective portion 35 further includes a second bearing seat 357 mounted on the inner housing 37. The second connector 354 of this embodiment is rotatably mounted on the second bearing seat 357 at one end away from the reflective lens 351.

[0068] In this embodiment, the first light source unit 31 can be composed of a first light source and a first mounting plate, the first light source is installed on the first mounting plate, and the first light source is preferably an LED light source or a laser light source. The second light source unit 32 can be composed of a second light source and a second mounting plate, the second light source is installed on the second mounting plate, and the second light source is preferably an LED light source or a laser light source.

[0069] In this embodiment, the dynamic projection device 3 also includes a first focusing portion 38 and a second focusing portion 39. The first focusing portion 38 is mounted on the periphery of the first light source and is located between the first light source portion 31 and the first pattern piece portion 33. The second focusing portion 39 is mounted on the periphery of the second light source and is located between the second light source portion 32 and the second pattern piece portion 34.

[0070] Preferably, the first light focusing portion 38 and the second light focusing portion 39 may be a light focusing lens or a light focusing lens group, and the imaging portion 36 may be an imaging lens or an imaging lens group.

[0071] In this embodiment, the pattern light that realizes the dynamic projection effect based on the high-frequency rotation of the reflector further includes a heat dissipation device 2 disposed inside the housing 1 .

[0072] The heat dissipation device 2 includes a heat conductor 21 and a radiator 22. One end of the heat conductor 21 is connected to the inner shell 37, and the other end is connected to the radiator 22. The first mounting plate of the first light source unit 31 and the second mounting plate of the second light source unit 32 can be directly mounted on the heat conductor 21.

[0073] In this embodiment, the heat dissipation device 2 further includes a heat dissipation fan 23 . The heat dissipation fan 23 is installed on the radiator 22 and located inside the housing 1 . The housing 1 is provided with an exhaust hole that cooperates with the heat dissipation fan 23 .

[0075] As a further preference, the radiator 22 of this embodiment is a fin-type radiator 22 , and there are multiple cooling fans 23 disposed on the side of the radiator 22 .

[0076] In this embodiment, the housing 1 includes a front housing 11 and a rear housing 12. The front housing 11 is disposed on the periphery of the inner housing 37. The imaging unit 36 is embedded in the front housing 11. The rear housing 12 is disposed behind the front housing 11. The heat sink 22 and the heat dissipation device are both installed inside the rear housing 12. One end of the thermal conductor 21 extends into the interior of the heat sink 22, while the other end penetrates from the rear housing 12 into the front housing 11 and abuts against the inner housing 37. The first mounting plate of the first light source unit 31 and the second mounting plate of the second light source unit 32 abut against the thermal conductor 21. As a result, heat generated by the first light source unit 31, the second light source unit 32, and other components and transferred to the inner housing 37 can be quickly transferred from the thermal conductor 21 to the heat sink 22. Combined with the cooling fan 23, rapid cooling is achieved, achieving excellent heat dissipation.

[0077] In this embodiment, the pattern light that realizes dynamic projection effect based on high-frequency rotation of the reflector further includes a mounting bracket 4 , which is rotatably mounted on the front shell 11 or the rear shell 12 and is formed with a mounting hole or a hanging hole.

[0078] In this embodiment, the control device 5 includes at least a control circuit board 52 electrically connected to electrical components such as the light source, the radiator 22, the cooling fan 23 and various driving parts, a controller 51 electrically connected to the control circuit board 52 and arranged on the housing 1, and an electronic driver 53 electrically connected to the controller 51 and installed on the housing 1.

[0079] Preferably, the controller 51 is installed on the surface of the front shell 11 or the rear shell 12, the control circuit board 52 is installed behind the controller 51 or in the space enclosed by the front shell 11 and the inner shell 37, and the electronic driver 53 is installed at the tail end of the rear shell 12.

[0080] In this embodiment, the control device 5 may further include a positioning sensing mechanism, which may be a combination structure of a sensor + a sensing sheet. The first pattern sheet portion 33, the second pattern sheet portion 34 and the reflecting portion 35 may all be equipped with a positioning sensing mechanism, and then cooperate with the controller 51 or the electronic drive 53 to achieve stopping and starting at a specified angle, thereby coordinating the start and shut down of the light source.

[0081] The working principle of the pattern light of the present invention that realizes dynamic projection effect based on high-frequency rotation of the reflector is as follows:

[0082] S1, the electronic driver 53 transmits power to the controller 51;

[0083] S2. The controller 51 activates the first light source unit 31 to emit a light beam, which is formed into a focused light beam under the action of the first focusing unit 38, i.e., a first incident light path;

[0084] S2. The first incident light path passes through one of the first light-transmitting holes 331a in the first pattern sheet 331 (assuming that pattern No. 1 is set in the first light-transmitting hole 331a);

[0085] S4. The electronic driver 53 controls the reflective lens 351 of the reflective unit 35 to rotate to a position at a 45-degree angle to the first incident light path. The reflective lens 351 receives pattern No. 1 and forms a first reflected light path, which is then projected through the imaging unit 36 to obtain pattern No. 1.

[0086] S5. While performing step S3, the controller 51 can control one of the second light-transmitting holes 341a in the second pattern sheet 341 (assuming that pattern No. 2 is set in the second light-transmitting hole 341a) to prepare at the position corresponding to the light-transmitting hole;

[0087] S6. The controller 51 controls the first light source 31 to turn off, and the electronic driver 53 controls the reflective lens 351 of the reflective portion 35 to rotate to a position at a 45-degree angle to the second incident light path, ready to receive pattern No. 2.

[0088] S7. The controller 51 activates the second light source unit 32 to emit a light beam. The light beam forms a focused light beam under the action of the second focusing unit 39, i.e., a second incident light path. The reflective lens 351 receives pattern No. 2 and forms a second reflected light path, which is then projected through the imaging unit 36 to obtain pattern No. 2.

[0089] S8. Repeat steps S1-S7 until all the effects on the first pattern piece 331 and the second pattern piece 341 are projected, and then loop.

[0090] As described above, the pattern light of the present invention that realizes dynamic projection effect based on high-frequency rotation of the reflector has at least the following advantages over the traditional projection device:

[0091] 1. The present invention provides a pattern light with a brand-new structure that realizes dynamic projection effects based on high-frequency rotation of a reflector. The pattern light adopts a light path generation structure of dual light sources + dual pattern pieces, and is combined with a reflective portion 35 capable of high-speed rotation, which can effectively solve the defects of a single pattern piece. By alternating the dual pattern pieces, not only can the speed and strobe requirements be halved, which can better guarantee the quality of accessories and technical requirements, but also the pattern effect can be doubled, thereby achieving a longer-lasting dynamic effect. The pattern light has the advantages of a long service life, good dynamic projection effect and long duration.

[0092] 2. The first pattern piece portion 33 drives the first pattern piece 331 to rotate through the first driving member 332, and the second pattern piece portion 34 drives the second pattern piece 341 to rotate through the second driving member 342. By controlling the start and stop of the first driving member 332 and the second driving member 342 and coordinating the strobing of the first light source portion 31 and the second light source portion 32, the operation is smooth and highly accurate, which can effectively solve the problems of jamming and position offset existing in traditional intermittent motion mechanical structures.

[0093] 3. The heat dissipation structure of heat conducting member 21 + radiator 22 + cooling fan 23 is adopted, and the heat conducting member 21 is in direct contact with the first light source unit 31 and the second light source unit 32 , which is not only compact in structure and small in size, but also has good heat dissipation effect.

[0099] As a further preferred embodiment, the output end of the transmission assembly 355 of this embodiment is in transmission connection with the first connector 353 , that is, the third transmission gear 355 c is sleeved on the outer periphery of the first connector 353 .

[0100] In this embodiment, the reflective portion 35 further includes a first bearing seat 356 and a second bearing seat 357, which are mounted on the inner housing 37.

[0104] Example 3

[0105] like Figure 20 As shown, the present invention provides a first pattern piece 331 and a second pattern piece 341 in one embodiment.

[0106] like Figure 20 The figure shows a top view of the first pattern piece 331 and the second pattern piece 341 in one embodiment of actual use. The first light-transmitting hole 331a of the first pattern piece 331 is provided with a set of digital patterns (including eight numbers), and the second light-transmitting hole 341a of the second pattern piece 341 is provided with another set of digital patterns (including eight numbers). By controlling the alternating playback, a continuous dynamic carousel of digital patterns can be formed. Under the same conditions, traditional lamps can only play eight numbers, while the present invention can play 16 numbers. Therefore, the dynamic projection lamp of the present invention has the advantage of doubling the pattern effect and achieving a longer-lasting dynamic effect.
