Description

Technical Field

[0001] The utility model relates to a lamp, in particular to an opening lamp for preventing light leakage. Background Art

[0002] An opening lamp mainly refers to a lamp that is embedded inside a ceiling and only exposes the lighting part on the outside. It is commonly installed indoors, such as a downlight and a spotlight. It usually includes a radiator, a light source, a lens, and a housing. The radiator serves to dissipate heat for the light source and also acts as the rear main body. The light source is installed between the radiator and the lens. The light source is used to generate light and cooperate with the lens to form a light beam. The outside of the housing is arranged in a gradually expanding cylindrical shape. The housing is connected to the front end of the radiator and cooperates with the radiator to limit the light source and the lens. The shape of the housing constrains the light beam. During the use of the opening lamp, such as a spotlight, the light beam is relatively concentrated. In order to obtain a better irradiation angle and atmosphere creation effect, it is often necessary to adjust and optimize the angle in cooperation with other indoor lamps to better meet the needs of users. The adjustment of the light beam of the opening lamp is generally completed by adjusting the orientation and angle of the housing. However, for the opening lamp of the prior art, during the swinging or rotating process of the housing, a certain gap is often generated between the housing and the radiator, resulting in the light generated by the light source directly spilling out onto the ceiling. To achieve the corresponding lighting effect, a higher power is often required. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an opening lamp for preventing light leakage, which can prevent light leakage while ensuring convenient adjustment of the light beam angle.

[0004] To achieve the above object, the utility model provides an opening lamp for preventing light leakage, including a radiator, a light source, and a lens. The radiator includes a lamp slot for installing the light source and the lens, and also includes an inner ring and a lamp cup. A lamp hole for the light beam to pass through is formed between the inner ring and the lamp cup. The rear end of the inner ring is inserted into the lamp slot and abuts against the lens, and the inner ring is rotationally connected and cooperated with the radiator. The lamp cup is sleeved on the outer side of the front end of the inner ring, and the lamp cup can swing up and down relative to the inner ring.

[0005] The advantages of adopting the above technical solution are as follows: An inner ring and a lamp cup are provided with light holes for the sightseeing beam to pass through. The rear end of the inner ring is inserted into the lamp slot and abuts against the lens. The inner ring cooperates with the radiator to limit the lens. Then, the inner ring and the radiator are rotationally connected and matched. The lamp cup is sleeved outside the inner ring and can swing up and down relative to the inner ring. When the user needs to adjust the beam orientation, the inner ring can be rotated first and then the lamp cup can be swung. Since the adjustment of the beam orientation is achieved through two components, the inner ring only needs to rotate and the lamp cup only needs to swing, which can reduce the movement amplitude and structural difficulty of a single component and avoid the phenomenon of light leakage at the connection caused by meeting the adjustment requirements.

[0006] The utility model can be further arranged as follows: The inner ring includes a movable connection part at the front end. The movable connection part is arranged to extend gradually and decrease in an arc shape. The lamp cup includes a sleeved part.

The sleeved part is sleeved on the movable connection part. Since the movable connection part extends gradually and decreases in an arc shape, the sleeved part sleeved on the outside can be in sliding contact with it. Finally, raised parts are arranged on both sides of the sleeved part and are in screw connection and cooperation with the inner ring to form a limit on the movement direction, so that only up-and-down swinging can be performed.

[0008] The utility model can be further arranged as follows: The lamp cup includes an inner ring edge. An abutting arc surface that is in sliding contact with the movable connection part is arranged on the inner ring edge.

[0009] Through further arrangement, an inner ring edge is arranged on the lamp cup, so that the inner ring edge and the sleeved part are in sliding contact with the movable connection part together, strengthening the stability of the cooperation between the lamp cup and the movable connection part.

[0010] The utility model can be further arranged as follows: It includes a locking piece. A card slot for the locking piece to be embedded is arranged at the movable contact part near the screw connection and cooperation with the sleeved part. There is a gap between the sleeved part and the inner ring edge, and limiting rib strips are arranged at the gap corresponding to the card slot between the sleeved part and the inner ring edge. The limiting rib strips are in abutting and cooperating with the locking piece.

[0011] Through further arrangement, a locking piece is arranged, a card slot is arranged on the movable contact part, and limiting rib strips are arranged at the gap corresponding to the card slot between the sleeved part and the inner ring edge. The locking piece embedded in the card slot abuts against the limiting rib strips to form a limit, so that the inner ring and the lamp cup cannot swing, to meet the needs of some situations where adjustment is not required.

[0012] The utility model can be further configured as follows: the inner ring includes a plurality of clamping blocks arranged at circumferential intervals, the clamping blocks extend towards the lamp slot and are provided with tapered hook parts at the ends, a limiting rib is arranged in the lamp slot, and the large ends of the hook parts and the lower edge of the inner ring can abut against both sides of the limiting rib.

[0013] Through further configuration, when inserting the inner ring, after the hook parts of the clamping blocks pass through the limiting rib, then make the clamping blocks and the lower edge of the inner ring abut against both sides of the limiting rib, so as to form a structure that can rotate relatively but the insertion and extraction directions can be limited.

[0014] The utility model can be further configured as follows: the radiator includes an annular groove, the annular groove is arranged at the end of the radiator corresponding to the lamp slot and surrounds the lamp slot, the inner ring includes a limiting ring part located at the outer peripheral wall, and the limiting ring part can extend into the annular groove and slide along it when the inner ring is inserted into the lamp slot.

[0015] Through further configuration, by respectively arranging the annular groove and the limiting ring part on the radiator and the inner ring, when the radiator and the inner ring are completed with the plug-in fit, the limiting ring part can extend into the annular groove to provide the effect of enhanced limitation, and the sliding fit between the two can also enhance the guiding effect during the rotation of the inner ring relative to the radiator.

[0016] The utility model can be further configured as follows: it includes a honeycomb mesh, and the honeycomb mesh is arranged between the lens and the inner ring to cover the lens.

[0017] Through further configuration, the setting of the honeycomb mesh can meet the use requirements in places with particularly high requirements for the glare value.

[0018] The utility model can be further configured as follows: it further includes an outer ring, and the outer ring is detachably sleeved outside the lamp cup.

[0019] Through further configuration, by setting the outer ring detachably connected to the lamp cup, the outer ring can be installed according to the on-site requirements. By judging whether the user is for conventional embedding and pre-burial type, and then installing the outer ring, it can better meet the user's requirements.

[0020] The utility model can be further configured as follows: the outer ring includes a limiting ring surface located at its inner peripheral wall, the limiting ring surface alternately protrudes and depresses, and the lamp cup includes a spring hook, and the spring hook abuts against the limiting ring surface.

[0021] Through further setting, the limiting annular surface at the outer peripheral wall of the outer ring abuts against the spring hook on the lamp cup, which can limit the outer ring and the lamp cup. When the user's ceiling is equipped with a sound system or for other reasons, vibrations will occur during subsequent use. The limiting effect between the spring hook and the limiting annular surface can be utilized to prevent the adjusted irradiation angles of the two from rotating and shifting relative to each other due to rotation, thus better ensuring the product stability.

[0022] The utility model can be further set as follows: a shoulder and a steel wire handle are arranged on the inner ring close to the lamp cup. The steel wire handle is arranged in an arc shape and can swing to fit with the shoulder.

[0023] Through further setting, a shoulder and a steel wire handle are arranged at the lamp cup of the inner ring. During the embedded installation of the lamp, the steel wire handle can be swung and then pulled down to separate part of the lamp from the main body, facilitating subsequent maintenance. The setting of the shoulder can cooperate with the steel wire handle to provide a limiting and hidden effect, which is more beautiful and practical. Description of the Drawings
