[0032] See also Figures 1 to 3 The first embodiment of the present invention provides a light output module, which includes:

[0033] A light source board 10, wherein at least two lamp beads 11 are provided on the light source board 10;

[0034] The reflective cup 20 is provided on the light source board 10. The reflective cup is integrally formed and includes a plurality of first light-concentrating portions 21 and first light-flooding portions 22. At least one first light-concentrating portion 21 is provided corresponding to the lamp bead 11; and at least one first light-flooding portion 22 is provided corresponding to the lamp bead 11.

[0035] The transmissive member 30 is provided on the reflective cup 20. The transmissive member 30 is integrally formed and has a second light-focusing portion 31 matching the first light-focusing portion 21 and a second light-flooding portion 32 matching the first light-flooding portion 22. The first light-focusing portion 21 and the second light-focusing portion 31 cooperate to form a focusing on the lamp bead 11; the first light-flooding portion 22 and the second light-flooding portion 32 cooperate to form a floodlight on the lamp bead 11.

[0036] In this embodiment, the lamp beads 11 may be LED lamp beads, and the light source board 10 may be a PCB circuit board. The lamp beads 11 are arranged on the light source board 10, so that the light source board 10 can control the lamp beads 11 to be in a lighting state or an off state.

[0037] In this embodiment, the reflective cup 20 can be integrally formed by injection molding, and includes a plurality of first light-concentrating portions 21 and first floodlight portions 22 , wherein the first light-concentrating portions 21 and the first floodlight portions 22 are provided with lamp beads 11 .

[0038] Specifically, the first light collecting part 21 is in the shape of an inverted hollow circular truncated cone, which includes a bottom plane in the shape of a circle arranged on the light source plate 10 and a top plane away from the light source plate 10, the lamp bead 11 is arranged at the center of the bottom plane, and the ratio of the diameter of the top plane to the diameter of the lamp bead is 1.5-2:1; wherein the beam angle of the first light collecting part is 70-90 degrees.

[0039] In the embodiment, the beam angle can also be referred to as the light emitting angle of the first light collecting part, which is defined as the included angle formed by the boundary line of the light range on the tangent plane of the optical axis. The smaller the beam angle, the more concentrated the light beam, and vice versa, the more divergent the light beam.

[0040] Specifically, the diameter of the top plane of the first light collecting part 21 is 10-13 mm; the diameter of the bottom plane is 6-8 mm, the distance between the top plane and the light source plate is 5-9 mm, and the beam angle is 80 degrees.

[0041] In the embodiment, the first floodlight part 22 is also in the shape of an inverted hollow circular truncated cone. The first floodlight part 22 includes a bottom plane in the shape of a circle arranged on the light source plate 10 and a top plane away from the light source plate, the lamp bead 11 is arranged at the center of the bottom plane, and the ratio of the diameter of the top plane to the diameter of the lamp bead is 5-6:1, and the beam angle of the first floodlight part 22 is 100-130 degrees.

[0042] Specifically, the diameter of the top plane of the first floodlight part 22 is 17-22 mm; the diameter of the bottom plane is 5-7 mm, the distance between the top plane and the light source plate is 5-9 mm, and the beam angle is 110 degrees.

[0043] In the embodiment, the above-mentioned diameter, distance and angle of the light collecting part and the floodlight part can effectively limit the emitted light within the set angle range, avoiding light leakage. In addition, when the illumination is turned on, whether it is only turned on for light collection or only turned on for floodlight or turned on for both light collection and floodlight, the maximum output light intensity can be improved due to the cooperation of the reflecting cup 20 and the transparent member 30. Experiments show that the maximum output light intensity of the embodiment can be improved by 500-1000 cd compared with the case without reflecting cup.

[0044] In addition, it should be noted that the first light collecting part 21 and the first floodlight part 22 are parallel and the centers are located on the same line, so the bottom plane and the top plane of the first light collecting part 21 and the first floodlight part 22 are also in the same plane.

[0045] In the embodiment, the transparent member 30 can also be integrally formed by the injection molding process. The second light collecting part 31 comprises a frustum 311 which can be embedded and attached in the first light collecting part 21, and a spherical lens 312 connected with the frustum 311, wherein the frustum 311 can be provided with a light source hole, and the lamp bead 11 can be arranged in the light source hole.

[0046] In the embodiment, the second floodlight part 32 is a planar lens which is adapted to the top plane of the first floodlight part 21.

[0047] In the embodiment, particularly, the heat dissipating member is further arranged between the reflector cup 20 and the light source plate 10.

[0048] The heat dissipating member can be an aluminum plate, for example, which is used to increase the heat dissipation of the light emitting module, so as to avoid the high working temperature of the light emitting module. It can be understood that the heat dissipating member also has a light source hole which is adapted to the lamp bead 11.

[0049] The assembly process and working principle of the embodiment are described in detail below.

[0050] In the embodiment, during the assembly, the transparent member 30 is first sleeved on the reflector cup 20, and then is mounted on the light source plate 10, so that the light source hole is adapted to the lamp bead 11. Since the reflector cup 20 and the transparent member 30 are integrally formed, the assembly process is very simple, and the light emitting module can be made lighter and thinner, so as to reduce the overall volume of the light emitting module.

[0051] During the working, the user can control the working state of each lamp bead 11 according to the actual needs, so as to realize the light effect of spotlighting, floodlighting, or simultaneous spotlighting and floodlighting, which enriches the optical effect and meets the practical needs in different scenes.

[0052] The second embodiment of the utility model further provides a lamp, which comprises a lamp body 40 and the light emitting module as described above, and the light emitting module is assembled in the lamp body 40.

[0053] Particularly, the side surface of the reflector cup 20 is provided with a step or a clamping groove for facilitating the installation, and the light emitting module is assembled on the lamp body 40 through the step or the clamping groove.

[0054] In the embodiment, the light emitting module is assembled in the lamp body 40 through the step or the clamping groove. Figures 4 to 7, particularly, the lamp further comprises a top block 50, a spring 60, a first clamping part 70, and a rotating gear 71, one end of the first clamping part 70 is rotatably connected to one end of the lamp body 40 through a first rotating shaft 72, the rotating gear 71 is arranged at one end of the first clamping part 70, the top block 50 is arranged at one end of the lamp body 40 through the spring 60, and the rotating gear 71 is configured to form continuous elastic contact with the top block 50 when the first clamping part 70 rotates relative to the lamp body.

[0055] Specifically, in the embodiment, the first clamping part 70 is used to clamp the lamp as a whole in a target environment, such as being clamped on various rods, etc. The lamp body 40 is provided with two sleeve holes 41 at one end, the rotating gear 71 has a through hole and is arranged between the two sleeve holes 41, the first rotating shaft 72 passes through the through hole of the rotating gear 71 and is fixed on the two sleeve holes 41, so that the first clamping part 70 is rotatably connected to the lamp body 40.

[0056] The two sleeve holes 41 are further provided with a plurality of spring holes, and the spring 60 is partially or entirely arranged in the spring holes. One end of the top block 50 is connected to the spring 60, and the other end is in elastic contact with the toothed portion of the rotating gear 71.

[0057] When the lamp is fixed and the light emitting angle needs to be adjusted, the lamp body 40 can be rotated. At this time, the top block 50 generates an outwardly top resistance to the rotating gear 71 under the action of the spring 60, and the resistance periodically changes with the rotation of the rotating gear 71, being larger when the top block 50 is in contact with the toothed portion of the rotating gear 71 and being smaller when the top block 50 is in contact with the gear groove of the rotating gear 71, thereby generating a rotating gear position feeling and improving the rotating experience of the user.

[0058] When the lamp body 40 is adjusted to the required angle, the top block 50 can resist the rotating gear 71 under the action of the resistance in the absence of external force, thereby ensuring the relative fixation of the lamp body 40 and the lamp clamping part 70.

[0059] Further, the lamp further comprises a second clamping part 80, the second clamping part 80 is rotatably connected to the first clamping part 70 through a second rotating shaft 81 and a torsion spring 82, and the second rotating shaft 81 is non-parallel to the first rotating shaft 72.

[0060] The second clamping part 80 can be used to quickly clamp the lamp body 40 to the lamp strip, and the lamp strip can be worn on the head of a human body to form a head lamp, so that the user can achieve the lighting effect without holding the head lamp in some cases.

[0061] In the embodiment, the first rotating shaft 72 and the second rotating shaft 81 are non-parallel, that is, the first clamping part 70 and the second clamping part 80 have different rotating directions, so that the rotating freedom of the lamp can be improved, and the angle adjustment in more dimensions can be realized.

[0062] The above is the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements are also considered to be within the scope of protection of the present application.
