Detailed Embodiments

[0027] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the utility model.

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model.

[0029] Please refer to Figure 1 , an illumination device 10 is proposed in an embodiment of the present utility model. The illumination device 10 has an illumination function and can be used indoors or outdoors to meet the daily life and work needs of users.

[0030] Please refer to Figure 1 and Figure 2 , the illumination device 10 may include a condenser lens 100, a first light source assembly 200, and a second light source assembly 300. The first light source assembly 200 and the second light source assembly 300 may be located on the same side of the condenser lens 100. The first light source assembly 200 and the second light source assembly 300 can be independently turned on. The emitted light of the first light source assembly 200 can pass through the condenser lens 100 to form a first light beam, and the emitted light of the second light source assembly 300 can pass through the condenser lens 100 to form a second light beam. The divergence angle of the first light beam is not equal to the divergence angle of the second light beam. In this way, the user can choose to turn on the first light source assembly 200 or the second light source assembly 300 according to different illumination needs, so that the illumination device 10 forms a first light beam or a second light beam with different divergence angles, thereby enabling the light beam of the illumination device 10 to form different spot effects on the receiving surface (for example, the area of the spot is different). Compared with the illumination device in the related art, the illumination device 10 of the present application does not need to be provided with a mechanical adjustment structure to adjust the divergence angle of the light beam of the illumination device 10, which helps to reduce the overall volume of the illumination device 10.

[0031] In addition, since the illumination device 10 of the present application does not need to be provided with a mechanical adjustment structure, the installation process of the illumination device 10 is more convenient, and at the same time, it helps to reduce the maintenance cost and difficulty of the illumination device 10.

[0032] In some embodiments, the illumination device 10 may further include a controller. The controller may be electrically connected to the first light source assembly 200 and the second light source assembly 300, so that the controller can control the turning on and off of the first light source assembly 200 and the turning on and off of the second light source assembly 300.

[0033] In some embodiments, the controller may be a microprocessor or a microcontroller unit, having an integrated wireless transceiver module, such as a Wi-Fi module, a Bluetooth module, or a ZigBee module, enabling a user to remotely control the controller via a smart phone, a tablet computer, or a dedicated remote controller, thereby controlling the turning on and off of the first light source assembly 200 and the turning on and off of the second light source assembly 300, and further enabling the user to change the divergence angle of the light beam of the lighting device 10 without directly contacting the lighting device 10.

[0034] In some embodiments, the divergence angle of the emitted light of the first light source assembly 200 is not equal to the divergence angle of the emitted light of the second light source assembly 300. Wherein, the distance from the first light source assembly 200 to the condenser lens 100 is equal to or approximately equal to the distance from the second light source assembly 300 to the condenser lens 100, so that the divergence angle of the first light beam is not equal to the divergence angle of the second light beam.

[0035] In other embodiments, the divergence angle of the emitted light of the first light source assembly 200 is equal to the divergence angle of the emitted light of the second light source assembly 300. Wherein, the distance from the first light source assembly 200 to the condenser lens 100 is not equal to the distance from the second light source assembly 300 to the condenser lens 100, so that the divergence angle of the first light beam is not equal to the divergence angle of the second light beam.

[0036] In some embodiments, the number of the first light source assemblies 200 may be multiple, and the emitted light of the multiple first light source assemblies 200 can pass through the condenser lens 100 to form a first light beam. Thus, the condenser lens 100 can converge and mix the light spots of the emitted light of the multiple first light source assemblies 200, which helps to make the first light beam of the lighting device 10 have better light spot consistency.

[0037] In some embodiments, the number of the second light source assemblies 300 may be multiple, and the emitted light of the multiple second light source assemblies 300 can pass through the condenser lens 100 to form a second light beam. Thus, the condenser lens 100 can converge and mix the light spots of the emitted light of the multiple second light source assemblies 300, which helps to make the second light beam of the lighting device 10 have better light spot consistency.

[0038] In some embodiments, the multiple first light source assemblies 200 may be arranged at intervals in sequence along the circumferential direction of the axis of the condenser lens 100, and the multiple second light source assemblies 300 may be arranged at intervals in sequence along the circumferential direction of the axis of the condenser lens 100, and each first light source assembly 200 may be located between two adjacent second light source assemblies 300. Thus, the multiple first light source assemblies 200 and the multiple second light source assemblies 300 are arranged alternately in sequence, enabling the lighting device 10 to more effectively utilize the emitted light of each light source assembly, reducing the waste of the emitted light, and thus helping to improve the energy efficiency of the lighting device 10.

[0039] In some embodiments, the lighting device 10 may further include a third light source assembly 400. The first light source assembly 200, the second light source assembly 300, and the third light source assembly 400 are located on the same side of the condenser lens 100. The first light source assembly 200, the second light source assembly 300, and the third light source assembly 400 can be independently turned on respectively. The light emitted by the third light source assembly 400 can pass through the condenser lens 100 to form a third light beam, and the divergence angle of the third light beam is not equal to the divergence angles of the first light beam and the second light beam. In this way, the user can choose to turn on the first light source assembly 200, the second light source assembly 300, or the third light source assembly 400 according to different lighting requirements, so that the lighting device 10 forms a first light beam, a second light beam, or a third light beam with different divergence angles.

[0040] In some embodiments, a plurality of first light source assemblies 200 are arranged at intervals in sequence around the circumference of the third light source assembly 400, and a plurality of second light source assemblies 300 are arranged at intervals in sequence around the circumference of the third light source assembly 400. In this way, the plurality of first light source assemblies 200 and the plurality of second light source assemblies 300 can be arranged in a substantially annular shape and surround the outer circumference of the third light source assembly 400, so that the third light source assembly 400, the plurality of first light source assemblies 200, and the plurality of second light source assemblies 300 can be arranged neatly and orderly, thereby making the structure of the lighting device 10 relatively compact, and further making the volume of the lighting device 10 relatively small.

[0041] In some embodiments, the power of the third light source assembly 400 is greater than the powers of the first light source assembly 200 and the second light source assembly 300. In this way, since the number of the third light source assemblies 400 is less than the number of the first light source assemblies 200 or the number of the second light source assemblies 300, and the power of the third light source assembly 400 is greater than the powers of the first light source assembly 200 and the second light source assembly 300, the brightness of the third light beam can be kept substantially consistent with the brightness of the first light beam or the second light beam.

[0042] In some embodiments, the first light source assembly 200 includes a first light source 210 and a first lens 220. The light emitted by the first light source 210 sequentially passes through the first lens 220 and the condenser lens 100. The second light source assembly 300 includes a second light source 310 and a second lens 320. The light emitted by the second light source 310 sequentially passes through the second lens 320 and the condenser lens 100. The divergence angle of the light emitted by the first light source 210 is equal to the divergence angle of the light emitted by the second light source 310. The divergence angle of the light beam of the light emitted by the first light source 210 passing through the first lens 220 is not equal to the divergence angle of the light beam of the light emitted by the second light source 310 passing through the second lens 320. Specifically, the distance from the first light source 210 to the first lens 220 is equal to or approximately equal to the distance from the second light source 310 to the second lens 320. The first light source 210 and the second light source 310 may correspond to different types of lenses. For example, the first lens 220 is a plano-concave lens, and the second lens 320 is a biconvex lens, so that the divergence angle of the light emitted by the first light source assembly 200 is not equal to the divergence angle of the light emitted by the second light source assembly 300.

[0043] In some embodiments, the first light source assembly 200 further includes a first light blocking structure 230. The first light blocking structure 230 is connected between the first light source 210 and the first lens 220 and is disposed circumferentially around the optical axis of the light emitted by the first light source 210. Among them, the overall outer contour of the first light blocking structure 230 may be substantially annular. The first light source 210 may include a first circuit board 211 and a first lamp bead 212. The first lamp bead 212 is mounted on the first circuit board 211. The first light blocking structure 230 is connected between the first circuit board 211 and the first lens 220. The first light blocking structure 230, the first circuit board 211, and the first lens 220 may form a closed first accommodation space, and the first lamp bead 212 is located in the first accommodation space. The light-emitting surface of the first lamp bead 212 faces the first lens 220, so that the light emitted by the first lamp bead 212 exits from the first lens 220. Thus, the first light blocking structure 230 can block the light scattered by the first light source 210 and prevent the light scattered by the first light source 210 from randomly entering the second light source assembly 300.

[0044] In addition, the first light blocking structure 230 can effectively change the propagation direction of the light scattered by the first light source 210, which helps to reduce the risk of the light scattered by the first light source 210 exiting to the second light source assembly 300, and thus helps to reduce the risk of light pollution caused by the light scattered by the first light source 210 to the surrounding environment.

[0045] There are various choices for the first light blocking structure 230. For example, the first light blocking structure 230 can be made of a metal material; for another example, the first light blocking structure 230 can be made of a black plastic.

[0046] In some embodiments, the first light shielding structure 230 is provided with a first reflective coating, and the first reflective coating is located on one side of the first light shielding structure 230 facing the optical axis of the emitted light of the first light source 210. Specifically, the first reflective coating can be arranged facing the first lens 220. The first reflective coating can reflect the light scattered by the first light source 210 until the light scattered by the first light source 210 exits from the first lens 220, so that the first reflective coating can reflect the light scattered by the first light source 210 to the first lens 220, thereby helping to improve the light utilization rate of the first light source 210.

[0047] There are various choices for the first reflective coating. For example, the first reflective coating can be a metal reflective coating; for another example, the first reflective coating can be a polymer reflective coating; for still another example, the first reflective coating can be a ceramic reflective coating.

[0048] In some embodiments, the second light source assembly 300 further includes a second light shielding structure 330. The second light shielding structure 330 is connected to the second light source 310 and the second lens 320 and is arranged circumferentially around the optical axis of the emitted light of the second light source 310. Among them, the overall outer contour of the second light shielding structure 330 can be generally annularly arranged. The second light source 310 can include a second circuit board 311 and second lamp beads 312. The second lamp beads 312 are mounted on the second circuit board 311. The second light shielding structure 330 is connected between the second circuit board 311 and the second lens 320. The second light shielding structure 330, the second circuit board 311 and the second lens 320 can form two closed second accommodation spaces, and the second lamp beads 312 are located in the second accommodation spaces. The light-emitting surface of the second lamp beads 312 faces the second lens 320, so that the emitted light of the second lamp beads 312 exits from the second lens 320. In this way, the second light shielding structure 330 can block the light scattered by the second light source 310 and prevent the light scattered by the second light source 310 from randomly spreading to the first light source assembly 200.

[0049] In addition, the second light shielding structure 330 can effectively change the propagation direction of the light scattered by the second light source 310, which helps to reduce the risk of the light scattered by the second light source 310 exiting to the first light source assembly 200, thereby helping to reduce the risk of light pollution caused by the light scattered by the second light source 310 to the surrounding environment.

[0050] There are various choices for the second light shielding structure 330. For example, the second light shielding structure 330 can be manufactured using a metal material; for another example, the second light shielding structure 330 can be manufactured using black plastic.

[0051] The second light shielding structure 330 is provided with a second reflective coating, and the second reflective coating is located on one side of the second light shielding structure 330 facing the optical axis of the emitted light of the second light source 310. Specifically, the second reflective coating can face the second lens 320. The second reflective coating can reflect the light scattered by the second light source 310 until the light scattered by the second light source 310 exits from the second lens 320, so that the second reflective coating can reflect the light scattered by the second light source 310 to the second lens 320, thereby helping to improve the light utilization rate of the second light source 310.

[0052] There are various choices for the second reflective coating. For example, the second reflective coating can be a metal reflective coating; for another example, the second reflective coating can be a polymer reflective coating; for still another example, the second reflective coating can be a ceramic reflective coating.

[0053] In some embodiments, the third light source assembly 400 can include a third light source 410 and a third lens 420. The emitted light of the third light source 410 sequentially passes through the third lens 420 and the condenser lens 100. The third light source assembly 400 further includes a third light shielding structure 430. The third light shielding structure 430 is connected between the third light source 410 and the third lens 420 and is disposed circumferentially around the optical axis of the emitted light of the third light source 410. Among them, the overall outer contour of the third light shielding structure 430 can be generally annular. The third light source 410 can include a third circuit board 411 and third lamp beads 412. The third lamp beads 412 are mounted on the third circuit board 411. The third light shielding structure 430 is connected between the third circuit board 411 and the third lens 420. The third light shielding structure 430, the third circuit board 411, and the third lens 420 can form a closed third accommodation space, and the third lamp beads 412 are located in the third accommodation space. The light-emitting surface of the third lamp beads 412 faces the third lens 420, so that the emitted light of the third lamp beads 412 exits from the third lens 420. In this way, the third light shielding structure 430 can block the light scattered by the third light source 410 and prevent the light scattered by the third light source 410 from randomly spreading to the first light source assembly 200 and the second light source assembly 300.

[0054] In addition, the third light shielding structure 430 can effectively change the propagation direction of the light scattered by the third light source 410, which helps to reduce the risk of the light scattered by the third light source 410 exiting to the first light source assembly 200 or the second light source assembly 300, thereby helping to reduce the risk of light pollution caused by the light scattered by the third light source 410 to the surrounding environment.

[0055] There are various choices for the third light shielding structure 430. For example, the third light shielding structure 430 can be made of a metal material; for another example, the third light shielding structure 430 can be made of black plastic.

[0056] The third light blocking structure 430 is provided with a third reflective coating, and the third reflective coating is located on one side of the third light blocking structure 430 facing the optical axis of the emitted light of the third light source 410. Specifically, the third reflective coating can face the third lens 420. The third reflective coating can reflect the light scattered by the third light source 410 until the light scattered by the third light source 410 exits from the third lens 420, so that the third reflective coating can reflect the light scattered by the third light source 410 to the third lens 420, thereby helping to improve the light utilization rate of the third light source 410.

[0057] There can be various choices for the third reflective coating. For example, the third reflective coating can be a metal reflective coating; for another example, the third reflective coating can be a polymer reflective coating; for still another example, the third reflective coating can be a ceramic reflective coating.

[0058] In some embodiments, there can be various choices for the first lens 220. For example, the first lens 220 can be a convex lens; for another example, the first lens 220 can be a total internal reflection lens; for still another example, the first lens 220 can be a reflector cup.

[0059] In some embodiments, there can be various choices for the second lens 320. For example, the second lens 320 can be a convex lens; for another example, the second lens 320 can be a total internal reflection lens; for still another example, the second lens 320 can be a reflector cup.

[0060] In some embodiments, there can be various choices for the third lens 420. For example, the third lens 420 can be a convex lens; for another example, the third lens 420 can be a total internal reflection lens; for still another example, the third lens 420 can be a reflector cup.

[0061] In some embodiments, the first light source 210 can be an LED lamp or a laser, etc. The second light source 310 can be an LED lamp or a laser, etc. The third light source 410 can be an LED lamp or a laser, etc.

[0062] In some embodiments, the first lamp bead 212 is electrically connected to the first circuit board 211, the second lamp bead 312 is electrically connected to the second circuit board 311, the third lamp bead 412 is electrically connected to the third circuit board 411, and the controller is electrically connected to the first circuit board 211, the second circuit board 311, and the third circuit board 411, so that the user can select to turn on the first light source assembly 200, the second light source assembly 300, or the third light source assembly 400 through the controller.

[0063] Please refer to Figures 1 to 8, based on the above embodiments, the first lens 220 can be a plano-concave lens, the second lens 320 can be a biconvex lens, and the third lens 420 can be a concave-convex lens. The divergence angles of the emitted light of the first light source 210, the second light source 310, and the third light source 410 are substantially the same. The distances from the first light source 210 to the first lens 220, from the second light source 310 to the second lens 320, and from the third light source 410 to the third lens 420 are substantially the same. The distances from the first lens 220 to the condenser lens 100, from the second lens 320 to the condenser lens 100, and from the third lens 420 to the condenser lens 100. Among them, the divergence angle of the first light beam is greater than that of the third light beam, and the divergence angle of the second light beam is greater than that of the third light beam. Thus, the user can select to turn on the first light source assembly 200, the second light source assembly 300, or the third light source assembly 400 according to different lighting requirements, so that the lighting device 10 forms a first light beam, a second light beam, or a third light beam with different divergence angles, thereby enabling the light beam of the lighting device 10 to form different spot effects on the receiving surface.
