Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

The embodiment of the application discloses a lamp structure, as shown in fig. 1 to 7, including two parts that need to be assembled and disassembled, which are named as a first main body 1 and a second main body 2 in the embodiment. In some light fixtures, the first body 1 may be a light emitting module and the second body 2 may be a reflector module. The present embodiment will be described in detail below by taking the light emitting module as the first body 1 and the reflector module as the second body 2. For convenience of description, the light emitting module will be referred to by the reference numeral of the first mounting opening, and the reflector module will be referred to by the reference numeral of the second body. The light emitting module 1 may generally include a light distribution element (such as a lens, a light guide plate, a light homogenizing mask, etc.), a light source assembly (generally including a light source and a light source substrate), and a heat sink, which are sequentially arranged, and in some cases, the heat sink may also extend to form an assembly cavity to accommodate the light source assembly and the light distribution element. The arrangement structures of the light distribution elements, the light source assembly and the heat sink in the light emitting module are conventional structures, and are limited by space and are not described herein again.

The light emitting module 1 in this embodiment has a circular first mounting opening 12, and two clamping protrusions 10 are symmetrically disposed on two radial sides of the first mounting opening 12.

Have circular shape second installing port 24 on reflector module 2, the radial bilateral symmetry of second installing port 24 is provided with two joint cooperation portions 20, and joint cooperation portion 20 is including installation guide slot 200 and joint groove 202, and installation guide slot 200 sets up in the outside of joint groove 202 along the axial of second installing port 24, and the two separates through joint arris 204, and joint arch 10 can get into in the installation guide slot 200 by the one side of keeping away from joint groove 202. The installation guide 200 serves to guide and restrain the catching projection 10 from freely moving.

Clamping protrusion 10 or clamping ridge 204 is provided with an installation inclined surface, and when the clamping protrusion moves axially relative to installation guide groove 200, clamping protrusion 10 can be deformed by means of the installation inclined surface and passes through clamping ridge 204 to clamping groove 202 from installation guide groove 200. The mounting inclined surface may be provided only on the engaging protrusion 10 or only on the engaging rib 204, but it is preferable to provide the mounting inclined surfaces on both the engaging protrusion 10 and the engaging rib 204 for better guiding effect. For example, as shown in fig. 2, 3 and 5, the mounting slopes include a first mounting slope 100 disposed on the clipping protrusion 10 and a second mounting slope 2040 disposed on a side of the clipping rib 204 facing the mounting groove 200, and the first mounting slope 100 and the second mounting slope 2040 are matched with each other.

After the clamping projection 10 is located in the clamping groove 202, the clamping projection 10 can be clamped with the clamping groove 202. The clamping structure formed at this time only needs to ensure that the clamping projection 10 is not axially disengaged from the clamping groove 202, regardless of the problem of disassembly in this direction. Therefore, the clamping matching surface of the clamping protrusion 10 and the clamping groove 202 in the axial direction can be perpendicular to the axial direction, and even close to the installation guide groove 200 gradually from the notch to the groove bottom of the clamping groove 202 to form a barb structure.

In this embodiment, one side of one of the clamping grooves 202 is provided with a relief portion 22, and referring to fig. 3, a detaching inclined surface 2020 is provided at one side of the clamping groove 202 adjacent to the relief portion 22, and the detaching inclined surface 2020 extends from the groove bottom of the clamping groove 202 to the groove opening and gradually approaches the relief portion 22.

When the clamping protrusion 10 moves circumferentially relative to the clamping groove 202, that is, when the light emitting module 1 and the reflector module 2 rotate circumferentially relative to each other, the clamping protrusion 10 can be deformed by the dismounting inclined surface 2020 and get across the dismounting inclined surface 2020 to the avoiding portion 22 by the clamping groove 202, so that the clamping state of the light emitting module 1 and the reflector module 2 is released. That is to say, the dismantlement mode of sending out optical module 1 and reflector module 2 in this embodiment is through the circumferential direction, and not the axial breaks away from, consequently can not cause the influence to the dismantlement of sending out optical module 1 and reflector module 2 at axial joint structure, and the installation and the dismantlement of the optical module 1 and the reflector module 2 of the lamps and lanterns that consequently this embodiment provided are all very easy, and when sending out optical module 1 and reflector module 2 and using the axis to set up as vertical direction, still effectively avoided the problem that breaks away from by oneself under gravity.

In order to make the clamping protrusion 10 deform more easily under the action of the detachment slope 2020, a detachment matching surface 102 matching with the detachment slope 2020 can be further provided on the clamping protrusion 10. Since there are two snap projections 10, if the removal fitting surface 102 is provided on only one of the snap projections 10, it is necessary to align the snap projection 10 provided with the removal fitting surface 102 with the snap fitting portion 20 provided with the removal slope 2020 during mounting, which requires careful observation by the installer, which complicates the mounting process and increases the effort. In order to simplify the mounting complexity, it is therefore proposed to provide the release counter surfaces 102 simultaneously on both latching projections 10, so that the installer no longer has to look carefully, thus simplifying the mounting process.

Care should be taken when providing the disassembly mating surface 102 to avoid the disengagement of the snap projection 10 from the snap groove 202 without the disassembly bevel 2020 by means of the disassembly mating surface 102, which would cause unnecessary trouble to the disassembly process. This can be avoided by increasing the depth of the snap groove 202 where the detachment slope 2020 is not provided, or by decreasing the angle of inclination of the detachment mating face 102 and the detachment slope, etc.

In this embodiment, when the clamping protrusions 10 on both sides are clamped with the clamping matching part 20, only one of the clamping protrusions needs to be located at the periphery of the other clamping protrusion, wherein the clamping protrusions 10 can be arranged at the periphery, and the clamping matching part 20 can also be arranged at the periphery.

For example, as shown in fig. 1 to 7, when the clamping fit portion 20 is disposed on the periphery, the two clamping fit portions 20 are disposed opposite to each other, and the two clamping protrusions 10 are away from each other, and the clamping fit portion 20 is clamped and fitted with the clamping protrusion 10 from the radial outer side. When the light emitting module 1 and the reflector module 2 need to be disassembled, the light emitting module 1 is rotated, and the clamping protrusion 10 is pushed inwards and deformed under the action of the disassembling inclined plane 2020 until the light emitting module crosses the disassembling inclined plane 2020 and reaches the avoiding portion 22.

Similarly, when the latch projection 10 is located at the periphery (not shown), i.e. the two latch projections 10 are located opposite to each other, and the two latch mating parts 20 are away from each other, the latch projection 10 is in latch mating with the latch mating part 20 from the radial outside. When the light emitting module 1 and the reflector module 2 need to be disassembled, the light emitting module 1 is rotated, and the clamping protrusion 10 is pushed outwards under the action of the disassembling inclined surface 2020 until the clamping protrusion crosses the disassembling inclined surface 2020 and reaches the avoiding portion 22. In general, the first approach is easier to implement.

The entire first mounting opening 12 can be used as an extending section, and the second mounting opening 24 can be used as a receiving section, and the avoiding portion 22 is a gap extending from the reflector module 1 to the receiving section 24 (for convenience of description, the reference numeral of the second mounting opening is used below). When the engaging protrusion 10 engages with the engaging groove 202, the extending section 12 (for convenience of description, the reference numeral of the first mounting opening is used below) can extend into the receiving section 24 to improve the structural stability.

For the two parts which are usually connected, only the connection and fixation need to be completed, but for some lamps, such as spot lamps which need to be adjusted in angle, the light emitting module 1 and the reflector module 2 may also need to be capable of rotating relatively. In order to meet the above requirement, the light emitting module 1 in this embodiment can rotate relative to the reflector module 2 in the opening 22 by using the clamping matching structure of the clamping protrusion 10 and the clamping groove 202 as a rotation axis.

In order to keep the light emitting module 1 and the reflector module 2 relatively fixed when they are rotated to any angle, so as to keep the current posture, as shown in fig. 1, 4 and 7, the present embodiment may provide the damping portion 120 on the first mounting opening 12, and provide the damping fitting portion 244 on the second mounting opening 24. When the clamping protrusion 10 rotates relative to the clamping groove 202, a damping, i.e. a friction force, is generated between the damping portion 120 and the damping fitting portion 244, and under the action of the friction force, after the external rotational force is removed, the light emitting module 1 and the reflector module 2 can be stably maintained at the current angular posture.

Damping portion 120 and damping cooperation portion 244's structural style is various in this embodiment, as long as can guarantee to provide frictional force all the time when joint arch 10 rotates with joint groove 202, and the cooperation of damping portion 120 and damping cooperation portion 244 can not hinder joint arch 10 and the installation of joint cooperation portion 20 and dismantlement process simultaneously can.

For example, as shown in fig. 1, 4 and 7, the clamping protrusion 10 is disposed outside the extending section 12, and the damping portion 120 is located on one side of the clamping protrusion 10 away from the center of the light source module 1 and forms a gap with the clamping protrusion 10. The receiving section 24 further includes two symmetrically disposed engaging lugs 242, the snap-fit portion 20 is disposed on one side of the engaging lug 242 facing the center of the reflector module 2, and one side of the engaging lug 242 facing away from the center of the reflector module 2 is a damping fit portion 244.

Further, the damping portion 120 and the engaging lug 242 have a partial interference in the axial direction, and due to the interference, when the engaging protrusion 10 moves relative to the engaging groove 202 in the axial direction, the damping portion 120 or the engaging lug 242 is deformed by the other one so that both can pass through alternately. After the crossing, the damping part 120 and the damping matching part 244 will be jointed together and form a friction force under the action of the deformation force. This frictional force is maintained by the deformation until the snap projection 10 and the snap fitting portion 20 are released from the snap state.

In order to facilitate the damping part 120 to cross the coupling lug 242 and to fit the damping fitting part 244, the present embodiment recommends providing a guide slope on the damping part 120 or the coupling lug 242 so as to guide the damping part 120 to fit the damping fitting part 244. Of course, the guide slope may preferably include both the first guide slope 1200 provided on the damper portion 120 and the second guide slope 2420 provided on the engaging lug 242, and the first guide slope 104 and the second guide slope 2420 need to be matched with each other.

To sum up, the lamp structure that this application embodiment provided has still effectively avoided the problem that breaks away from by oneself under gravity when the installation with dismantle easily.

In the embodiments of the present application, the difference between the embodiments is described in detail, and different optimization features between the embodiments can be combined to form a better embodiment as long as the differences are not contradictory, and further description is omitted here in view of brevity of the text.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art.
