Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, a lamp cascade device according to a first embodiment of the present invention includes a base 10 and a cover 20, the base 10 has notches 11 at both ends for receiving ends of a lamp 1, respectively, and the cover 20 is detachably fixed to the base 10 and covers the notches 11. Referring to fig. 3 and 4, during installation, the end portions of two adjacent lamps 1 are respectively clamped into the notches 11 at the two ends of the base 10, and the cover plate 20 covers the notches 11 for fixation, that is, the two adjacent lamps 1 are effectively and fixedly connected through the base 10 and the cover plate 20, so that the connection reliability and the design consistency are maintained, and the light emitting effect is designed.

Specifically, the cover plate 20 is generally a light-transmitting cover plate, and the light-transmitting cover plate is fixed to the base 10 in a snap-fit manner, so that the problem of inconvenience in operation due to narrow installation space of the blind groove is solved. For example, a clamping mode that a buckle is matched with a clamping hole and a clamping groove can be adopted, and the installation only needs to be aligned and pressed in place; the clamping rail form which is matched with each other can be adopted, during installation, the light-transmitting cover plate is aligned with the base 10, and the light-transmitting cover plate can be fixed by pushing the light-transmitting cover plate from one end of the clamping rail to the other end of the clamping rail. The light-transmitting cover plate is generally made of transparent plastic materials, so that the light emitted from the end part of the lamp is prevented from being shielded. The base 10 does not generally block the light, but may be made of transparent plastic material if necessary.

The lamp cascade device of the embodiment is particularly suitable for cascading linear lamps, and certainly, can also be suitable for connecting other lamps. When the linear lamps are cascaded, the notches 11 at the two ends of the base 10 can be on a straight line, so that the linearity of the cascaded linear lamps is ensured; the notches 11 at both ends may also be angled so that a specific shape, such as a star shape, can be spliced by a linear light fixture. The notches 11 at both ends may also be on the same arc, so that they are spliced to form a circular or arc pattern.

In general, the linear lamp is installed in a cascade straight line, so as to exert the advantage of light emitting linearity, and the embodiment also takes a lamp cascade device applicable to the linear lamp, in which the notches 11 at the two ends of the base 10 are on a straight line as an example, and other cases are similar and will not be described again.

As described in detail with reference to fig. 1 and 2, the base 10 includes a bottom plate 12 and two side walls 13 extending upward from two sides of the bottom plate 12, a slot 11 is formed between the bottom plate 12 and the two side walls 13 at two ends of the base 10, and the slot 11 has a specific shape matching with a lamp, and may be substantially square or have a certain arc, and is not particularly limited. According to needs, can set up elastic light-permeable's bolster on the lateral wall 13 of notch 11 to guarantee that lamps and lanterns tip card goes into the tightness of notch 11, in addition, the notch inside can also set up corresponding limit structure, thereby restriction lamps and lanterns are along base 10 length direction's position. Clamping slot holes 14 are respectively arranged at the outer sides of two side walls 13 of the base 10, and an elastic claw 21 clamped with the clamping slot holes 14 is arranged on the cover plate 20. During installation, the cover plate 20 can be fastened and fixed on the base 10 only by aligning the elastic claws 21 with the clamping groove holes 14 and pressing, so that the problems of narrow installation space and inconvenient operation of the hidden groove are solved.

Preferably, as shown in fig. 1 to 4, there are two cover plates 20, two cover plates 20 correspond to the notches 11 at the two ends of the base 10, and accordingly, two snap-in slots 14 corresponding to the two cover plates 20 are formed at the outer side of each side wall 13. That is, the ends of the two lamps are respectively butted with the base 10 and are respectively fixed by the cover plate 20, so that the convenience of operation during installation can be further improved compared with the mode that the two lamp ends are integrally fixed by the cover plate 20.

As shown in fig. 1 and fig. 2, each cover plate 20 has one elastic claw 21 at each of four corners, that is, each cover plate 20 has four elastic claws 21, and the four elastic claws 21 all extend toward the base 10. Each of the latch slots 14 includes a latch protrusion 141 at both ends and a limiting sidewall 142 connecting the latch protrusion 141, the latch protrusion 141 protrudes outward from the sidewall 13 of the base 10, and the limiting sidewall 142 is parallel to the sidewall 13 of the base 10, i.e. two elastic claws 21 on the same side of the cover plate 20 correspond to one latch slot 14. During installation, the two elastic claws 21 penetrate through the clamping groove holes 14 formed by the limiting side walls 142 and the clamping protrusions 141 and then are clamped and matched with the clamping protrusions 141 at two ends respectively, the space in the length direction of the clamping groove holes 14 formed in the way is large, positioning is convenient, for example, after the elastic claws 21 at one end enter the clamping groove holes 14, the elastic claws 21 at the other end can be moved towards the end and pressed, and the elastic claws 21 at the other end can enter the clamping groove holes 14 conveniently. The front end of the resilient jaws 21 may be provided with an arcuate or inclined guide to facilitate insertion into the snap slot 14, as desired.

Preferably, as shown in fig. 2, in the first embodiment, the lamp cascade device further includes a power supply connection device 40, the power supply connection device 40 is disposed in the middle of the base 10, and the power supply connection device 40 is provided with a connection terminal 41 connected to the two lamps 1. The connecting terminal 41 is directly inserted into a connecting hole at the end of the lamp, so that the connection is more convenient and faster. The specific shapes and layouts of the power connection device 40 and the connection terminals 41 are designed according to different lamp requirements, and are not particularly limited.

Specifically, as shown in fig. 2, a recess 15 that is upwardly concave is provided on the bottom surface of the middle portion of the base 10, a terminal hole 16 is provided on the top of the recess 15, the power supply connection device 40 is fixed in the recess 15, and the connection terminal 41 passes through the terminal hole 16.

According to the requirement, a base buckle plate 17 can be further arranged, and the base buckle plate 17 is buckled on the groove 15 at the bottom, so that the power supply connecting device 40 is sealed inside to form protection. In addition, the mode that the power supply connecting device 40 is pressed and fixed in the groove 15 by the base buckle plate 17 can be directly adopted, and the fixing is simpler.

In addition, for a lamp whose end portions are not connected through a connection terminal, for example, a lamp directly connected through a power line, a wire passing slot hole through which the power line of the lamp passes may be further provided in the middle of the base 10, and the power line is introduced to the outside through the wire passing slot hole, so as to be connected with a power supply. The wire passing slotted hole is arranged, so that the range of the lamp cascade device suitable for the variety of lamps is expanded.

In the luminaire cascade device of the second embodiment as shown in fig. 5 to 10, on the basis of the first embodiment, at least one side of the base 10 is further provided with an elastic positioning member 30. As shown in fig. 11 and 12, by providing the elastic positioning member 30, the elastic positioning member 30 is matched with the side wall of the camera obscura 4 where the lamp 1 is installed, so that the lamp cascade device is conveniently positioned in the camera obscura 4, that is, the position of the lamp 1 in the camera obscura 4 is ensured to be fixed, and the light emitting effect is ensured.

As shown in fig. 12, the elastic positioning member 30 can be disposed on only one side of the base 10 according to the installation requirement of the lamp, so that the base 10 is installed on one side of the troffer 4, that is, one side wall 13 of the base 10 directly contacts with the side wall of the troffer, and the other side wall 13 of the base 10 contacts with the other side wall of the troffer through the elastic positioning member 30. The elastic positioning members 30 may also be disposed on both sides of the base 10, so as to position the base 10 in the middle of the hidden slot 4, i.e. both sides of the base 10 contact with the side walls of the hidden slot through the elastic positioning members 30. Different light-emitting effects can be realized by positioning the base 10 and the lamp at different positions of the camera obscura.

Preferably, as shown in fig. 6 to 8, the elastic positioning member 30 is detachably connected to the base 10, and during installation, whether the elastic positioning member 30 is installed or not is selected according to requirements, so as to meet different installation requirements. Specifically, at least one side of the middle of the base 10 is provided with a first connecting portion, and the elastic positioning member is provided with a second connecting portion connected with the first connecting portion. The first connecting portion and the second connecting portion are generally clamped, inserted and the like, and are simply fixed, for example, the matching structure of the connecting groove and the connecting protrusion, and the structure of the jack or the slot.

Specifically, in this embodiment, in consideration of the stability of connection, the first connection portion and the second connection portion adopt a matching structure of the connection groove and the connection protrusion, that is, the connection groove 2 is provided on one of the base 10 and the elastic positioning member 30, the connection protrusion 3 connected with the connection groove 2 is provided on the other of the base 10 and the elastic positioning member 30, and the connection protrusion 3 and the connection groove 2 are mutually clamped and matched, so as to realize detachable connection.

More preferably, the connecting groove 2 is disposed on the base 10, and the connecting protrusion 3 is disposed on the elastic positioning member 30, so as to avoid the contact area between the side wall 13 of the base 10 and the side wall of the camera obscura from being reduced due to the protrusion disposed on the base 10, and improve the reliability. In addition, as shown in fig. 8, the two sides of the middle of the base 10 can be provided with the connecting grooves 2, so that the elastic positioning members 30 can be freely and selectively installed on one side or two sides according to the installation requirements, thereby meeting the requirements of different installation positions and achieving different light emitting effects.

In addition, as shown in fig. 1 and 8, the connecting groove 2 is formed between the limiting side walls 142 of the two clamping groove holes 14 on the same side wall 13, so that on one hand, the plane of the limiting side walls 142 is the outer contact surface of the base, and the contact area is increased; on the other hand, the side wall 13 of the base 10 is not required to be provided with the connecting groove 2 separately, so that the whole structure is more compact,

further, as shown in fig. 6 to 8, the elastic positioning member 30 includes at least one elastic fitting 31; a first end of the elastic fitting 31 is provided with a coupling protrusion 3, and a second end of the elastic fitting 31 is provided with a coupling groove 2. When there is only one elastic fitting 31, the coupling projection 3 of the first end of the elastic fitting 31 is coupled with the coupling groove 2 of the base 10, and the second end of the elastic fitting 31 abuts against the side wall of the camera obscuration. When the number of the elastic fittings 31 is two or more, the connecting protrusion 3 at the first end of the second elastic fitting 31 can be connected to the connecting groove 2 at the second end of the first elastic fitting 31, that is, the connecting groove 2 and the connecting protrusion 3 are used to connect two adjacent elastic fittings 31, so as to extend the width of the whole elastic positioning member 30 and meet the requirement of a wider hidden slot. As shown in fig. 12, a design manner that the elastic fittings 31 can be connected to each other is adopted, and the connection manner of the elastic fittings 31 and the elastic fittings 31 is the same as the connection manner of the base 10, so that on one hand, the requirement of matching different chase widths can be realized by the way that the elastic fittings 31 are connected to each other, and on the other hand, one or more elastic fittings 31 can be adjusted from one side of the base 10 to the other side for installation, thereby realizing the position adjustment of the base 10 and meeting the requirements of installing different bases 10 at different positions.

Further, as shown in fig. 6, the elastic fitting 31 has an M-shape, and the M-shaped elastic fitting 31 can be directly and stably placed in the camera. The end plate part of the first end of the M-shaped elastic fitting 31 is provided with a connecting bulge 3 extending along the height direction of the end plate; the end plate part of the second end is provided with a connecting groove 2 extending along the height direction of the end plate. That is, the connecting protrusion 3 and the connecting groove 2 are connected by applying pressure in the up-down direction, and in the connecting process, no additional force in the lateral direction or other directions is applied to the base 10, so that the movement of the base 10 in the installation process is avoided.

Generally, as shown in fig. 1, 6 and 7, the connecting groove 2 extends from top to bottom, i.e. the opening of the connecting groove 2 is located at the top, and the elastic fitting 31 can be directly pressed from top to bottom in the process of fixing the blind groove. The connecting groove 2 may also extend from bottom to top, i.e. the opening of the connecting groove 2 is located at the bottom, and during installation, the elastic fittings 31 are required to be assembled on the base 10 first, or the elastic fittings 31 are connected with each other first, but during pressing into the blind groove, the elastic fittings 31 will not loosen.

As shown in fig. 6, the middle V-shaped tip of the M-shaped elastic fitting 31 is provided with a cutout 32, i.e. a part of the material of the V-shaped tip can be removed, so as to reduce the hardness of the elastic fitting 31, improve the elasticity thereof, and meet the requirement of large expansion and contraction.

Preferably, as shown in fig. 1 and 7, the cross sections of the connecting grooves 2 and the connecting protrusions 3 are T-shaped, which can effectively improve the structural strength of the connecting protrusions 3 and also improve the connection reliability of the connecting grooves 2 and the connecting protrusions 3.

As shown in fig. 11 and 12, the present invention further provides a lighting device, including at least two lamps 1 and the lamp cascade device, where two adjacent lamps of the at least two lamps are connected by the lamp cascade device, so as to ensure effective fixed connection of the adjacent lamps, maintain connection reliability and design consistency, and achieve a designed light emitting effect. When the lamp 1 is a linear lamp, the linearity of the connection of the linear lamp can be ensured, and the advantage of linear light emission of the linear lamp is exerted.
