DETAILED DESCRIPTION

[0022] The following will be combined with the attached embodiment of the present utility model Figure 1-6 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] As shown in the figure, a spotlight that is easy to replace a light cup 5 includes a radiator 1, a light source bracket 2, a light source 3, a lens 4, a light cup 5, a face ring 6, a connecting bracket 7 and a light cup bracket 8. The light source 3 is arranged on the light source bracket 2, and the light source bracket 2 is fixedly connected to the radiator 1 by screws. The lens 4 is fixedly connected to the light source bracket 2 and is opposite to the light source 3. The connecting bracket 7 is fixedly connected to the radiator 1. The light cup bracket 8 is connected to the connecting bracket 7. A plurality of snap-in plates 51 are formed on the outer surface of the light cup 5, and a first snap-in protrusion 52 is formed on the snap-in plate 51. A plurality of snap-in holes 81 matching the first snap-in protrusion 52 are opened on the light cup bracket 8. The cup 5 is placed in the optical cup bracket 8 so that the first clamping protrusion 52 is clamped into the clamping hole 81, thereby realizing the fixed connection between the optical cup 5 and the optical cup bracket 8. A clamping ring 61 is formed on the inner side surface of the face ring 6, and a plurality of second clamping protrusions 82 and third clamping protrusions 83 are formed on the outer side surface of the optical cup bracket 8. A clamping gap matching the thickness of the clamping ring 61 is formed between the second clamping protrusion 82 and the third clamping protrusion 83. The face ring 6 is sleeved on the outside of the optical cup bracket 8 so that the clamping ring 61 is clamped into the clamping gap, that is, the second clamping protrusion 82 and the third clamping protrusion 83 are respectively pressed against the two end surfaces of the clamping ring 61 to limit the clamping ring 61, thereby realizing the fixed connection between the face ring 6 and the optical cup bracket 8.

[0024] Specifically, a plurality of first elastic plates 84 are formed on the optical cup bracket 8 , the second clamping protrusions 82 are formed on the outer sides of the first elastic plates 84 , and the front ends of the first elastic plates 84 are chamfered.

[0025] Specifically, the structure in which the lens 4 is fixedly connected to the light source bracket 2 also includes a lens bracket 9 and a middle ring 10. Two L-shaped first snap-in grooves 21 are provided on the inner side surface of the light source bracket 2. The notches of the first snap-in grooves 21 penetrate the light source bracket 2 forward. Two first snap-in blocks 91 matching the first snap-in grooves 21 are formed on the rear end of the lens bracket 9. The first snap-in blocks 91 pass through the notches of the first snap-in grooves 21 and rotate to snap into the first snap-in grooves 21 to achieve a fixed connection between the lens bracket 9 and the light source bracket 2. A snap-in pin 92 is formed at the front end of the lens bracket 9. A second snap-in groove 41 matching the snap-in pin 92 is provided at the front end of the lens 4. The lens 4 is placed in the lens holder 9 so that the snap-in pin 92 is snapped into the second snap-in groove 41, thereby realizing a fixed connection between the lens 4 and the lens holder 9. A limiting step 101 is formed on the inner side of the middle ring 10. The middle ring 10 is sleeved outside the lens holder 9 and screwed into the radiator 1 so that the front end of the lens 4 is tightly against the limiting step 101, thereby realizing axial support for the lens 4 and ensuring the stability of the lens 4 after alignment with the light source 3. The structure in which the lens 4 is fixedly connected to the light source holder 2 does not require the use of tools and connectors, thereby facilitating the assembly of the lens 4, and the installation of the lens 4 is very stable, thereby ensuring the relative stability of the lens 4 and the light source 3 when the spotlight is working, thereby ensuring the lighting effect.

[0026] Specifically, the connecting bracket 7 is fixedly connected to the structure on the radiator 1: two L-shaped third clamping grooves 71 are opened on the outer side surface of the rear end of the connecting bracket 7, and the notch of the third clamping groove 71 passes through the connecting bracket 7 backwards, and two second clamping blocks 11 matching the third clamping grooves 71 are formed on the inner side surface of the radiator 1. The second clamping blocks 11 pass through the notch of the third clamping groove 71 and then rotate to be clamped into the third clamping groove 71 to achieve a fixed connection between the connecting bracket 7 and the radiator 1. The structure in which the connecting bracket 7 is fixedly connected to the radiator 1 does not require the use of tools and connectors, which is convenient for the assembly of the connecting bracket 7, and the installation of the connecting bracket 7 is very stable.

[0027] In the above embodiment, the spotlight is fixedly installed at the desired position for use through the face ring 6. When the light cup 5 needs to be replaced to meet the needs of different users for the irradiation light effect, the first elastic plate 84 is pushed inward through the gap between the light cup bracket 8 and the face ring 6, and the second clamping protrusion 82 is driven to swing inward to leave the position abutting against the clamping ring 61 and disengage the limit of the clamping ring 61, so that the clamping ring 61 can leave from the clamping gap, and the face ring 6 can move backward to expose the clamping hole 81, and then the first clamping protrusion 52 is pressed inward through the clamping hole 81 to drive the clamping plate 51 to swing inward, and the clamping plate 51 drives the first clamping protrusion 52 to swing inward to leave the clamping hole 81, and the light cup 5 can be removed from the face ring 6. The optical cup 5 is removed from the optical cup bracket 8, and then the optical cup 5 to be replaced is placed in the optical cup bracket 8 so that the first snap-in protrusion 52 is snapped into the snap-in hole 81 to achieve the fixed connection between the optical cup 5 and the optical cup bracket 8, and then the face ring 6 is pushed forward to make the snap-in ring 61 snap into the snap-in gap to achieve the fixed connection between the face ring 6 and the optical cup bracket 8, thereby realizing the replacement of the optical cup 5. The replacement process of the above-mentioned optical cup 5 is relatively convenient to operate, and it is easy to replace the optical cup 5 to meet the needs of different users for lighting effects, so that the spotlight has better applicability. In the above-mentioned process of replacing the optical cup 5, the purpose of setting the first elastic plate 84 is to make it easier for the user to push the second snap-in protrusion 82 to make the snap-in ring 61 escape from the snap-in gap.

[0028] Preferably, a plurality of second elastic plates 85 are formed on the optical cup holder 8, and a semi-cylindrical first limiting protrusion 86 is formed on the outer side surface of the second elastic plate 85. A plurality of second limiting protrusions 62 distributed in an array are formed on the inner side surface of the face ring 6. A limiting gap matching the first limiting protrusion 86 is formed between adjacent second limiting protrusions 62. The second limiting protrusion 62 is inserted into the limiting gap. The first limiting protrusion 86 cooperates with the limiting gap to limit the rotation of the face ring 6 on the optical cup holder 8, thereby ensuring the stability between the face ring 6 and the optical cup holder 8. After the face ring 6 is fixedly installed, the optical cup holder 8 and the optical cup 5 remain stable, thereby ensuring the lighting effect. By turning the face ring 6 with force to push the second elastic plate 85 to deform, the first limiting protrusion 86 moves between the limiting gaps at different positions, and the face ring 6 and the optical cup holder 8 can rotate relative to each other. This is particularly useful when the radiator 1 of the spotlight is non-cylindrical (for example Figure 1 When the radiator 1 is in the wolf-tooth type shown in the figure, the circumferential direction of the radiator 1 can be adjusted to adapt to different spotlight installation environments, thereby facilitating the installation and use of the spotlight.

[0029] Preferably, a semi-cylindrical third limiting protrusion 12 is formed on the inner side surface of the radiator 1, and a limiting groove 72 matching the third limiting protrusion 12 is opened on the outer side surface of the rear end of the connecting bracket 7. The third limiting protrusion 12 is inserted into the limiting groove 72 when the second clamping block 11 is inserted into the third clamping groove 71. The third limiting protrusion 12 cooperates with the limiting groove 72 to limit the rotation of the connecting bracket 7 relative to the radiator 1, thereby improving the stability of the connecting bracket 7 when it is fixedly connected to the radiator 1.

[0030] Preferably, the front end of the connecting bracket 7 extends into the light cup bracket 8, and two connecting screws are symmetrically arranged on the light cup bracket 8, which pass through the light cup bracket 8 and are screwed on the connecting bracket 7. The rear end of the light cup bracket 8 is oblique. Through the above structure, the connecting bracket 7 and the light cup bracket 8 can swing relative to each other in the axial direction, and the direction of the light source 3 is adjusted, thereby adjusting the irradiation angle, so that the spotlight has better applicability.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
