The present utility model provides a flexibly deformable hard linear lamp, comprising a plurality of light source assemblies 10 and a connection assembly 20 connecting the light source assemblies 10. The connection assembly 20 is flexibly snap-fitted into the first through hole 11 at adjacent ends of adjacent light source assemblies 10, so that both the spacing and included angle of two adjacent light source assemblies 10 can be adjusted within a certain range. Therefore, the deformation angle is flexible and the length varies flexibly; a single lamp can meet the deformation requirements, so that the cost is reduced, and at the same time the wiring is simple and aesthetic; the spacing of adjacent light sources may be consistent, so that the light spots are evenly distributed, and there is favorable light effect. It is suitable for both specially shaped projects and large-scale commercial lighting projects.

The first embodiment of the present utility model will be specifically described below.

Referring to FIG. 1, FIG. 1 is a schematic view of an overall structure in a normal state according to a first embodiment of the present utility model. The present utility model may be formed by connecting eight identical light source assemblies 10 shown in FIG. 1. In a normal state, the connected eight identical light source assemblies 10 maintain the same spacing and the same included angle (0 degree) , so that the entire lamp presents an elongated shape. The spacing between adjacent light source assemblies 10 is still maintained consistent, so that the light spots are evenly distributed, and there is a favorable light effect.

Referring to FIG. 1, the light source assembly 10 is provided with a second through hole 12 to accommodate an electric wire and to allow the electric wire to pass therethrough. Therefore, the electric wire may pass through the second through hole 12 and connect respective light source assemblies 10, so that the hard linear lamp of the present utility model has a simple and aesthetic wiring.

In addition, the lamp housing 13 is provided with an arc-shaped protrusion 131 that facilitates heat dissipation on both sides thereof, so as to optimize the heat dissipation effect of the hard linear lamp of the present utility model. The arc-shaped protrusion 131 is evenly provided with a plurality of strip-like grooves 132, so that an elastic piece 30 for installation can be snap-fitted and fixed to the strip-like groove 132. The specific installation manner will be described later in conjunction with FIG. 4.

Referring to FIG. 2, FIG. 2 is a schematic view of an overall structure in a curved state according to the first embodiment of the present utility model. The lamp formed by connecting eight identical light source assemblies 10 shown in FIG. 1 may be curved into a state shown in FIG. 2 by adjusting an included angle between adjacent light source assemblies 10. At this time, the spacing between adjacent light source assemblies 10 is still maintained consistent, so that the light spots are evenly distributed and there is a favorable light effect.

Obviously, if different numbers of light source assemblies 10 are selected, hard linear lamps having different lengths may be obtained. On such basis, the spacing and angle between adjacent light source assemblies 10 may be adjusted to obtain hard linear lamps with various different shapes (e.g., "S" , "J" ) , so as to be adapted for arc-shaped or irregular linear lighting occasions. The hard linear lamps adjusted into various shapes may be understood in conjunction with the first embodiment of the present utility model, and thus will not be described further herein.

Referring to FIG. 3, FIG. 3 is a first schematic view of an exploded structure in a curved state according to the first embodiment of the present utility model. The connection assembly 20 is flexibly snap-fitted into the first through hole 11 of adjacent light source assemblies 10 through a fastener 22 at both ends of the connection assembly. Therefore, the spacing and angle between adjacent light source assemblies 10 may be flexibly adjusted. The connection manner thereof will be described in more detail in conjunction with FIG. 5.

Referring to FIG. 5, FIG. 5 is a second schematic view of an exploded structure in a curved state according to the first embodiment of the present utility model. The fastener 22 includes a fixing screw 221, a wave washer 222, a plain washer 223, a gasket 224, and an antiskid nut 225. During assembling, the connecting piece 21 is first passed through the first through hole 11 in lamp covers 15 at adjacent ends of adjacent light source assemblies 10, and then the fixing screw 221, the wave washer 222, the plain washer 223, the gasket 224 and the antiskid nut 225 described above are assembled into a fastener 22, which is mounted at both ends of the connection assembly 20, and at the same time snap-fitted into an inside of the lamp cover 15 of the light source assembly 10. Since the width of the connecting piece 21 is less than that of the first through hole 11 and the height of the connecting piece 21 is less than that of the first through hole 11, the connection assembly 20 may adjust the angle and the exposed length within a certain range, thereby realizing the adjustment of the spacing and angle between adjacent light source assemblies 10.

Referring to FIG. 4, FIG. 4 is a schematic side view in a normal state according to the first embodiment of the present utility model. The hard linear lamp in the present utility model may be fixedly mounted on a contact surface such as a wall surface through the elastic piece 30. Specifically, the elastic piece 30 is first fixedly mounted on a contact surface such as a wall surface with a screw in the middle, and then the elastic piece 30 is snap-fitted and fixed to the arc-shaped protrusion 131 of the strip-like groove 132 in the lamp housing 13, so as to achieve the fixation of the elastic piece 30, the light source assembly 10 and the hard linear lamp, thereby fixedly mounting the hard linear lamp on the contact surface such as a wall surface.

Referring to FIGS. 6 and 7, FIGS. 6 and 7 are respectively two schematic views of an exploded structure of a light source assembly according to the first embodiment of the present utility model. The lamp housing 13 includes a lamp cover 15 detachably connected to both ends of the lamp housing 13. A cavity to accommodate the fastener 22 and to allow the movement of fastener 22 is provided at a position within the light source assembly 10 proximate to the lamp cover 15. The light emitting assembly 14 is designed to have a size matching the cavity, so that the light emitting assembly 14 can be stably accommodated within the lamp housing 13.

The light emitting assembly 14 includes a cylindrical lens housing 141, an LED 142 disposed on the bottom of the lens housing 141, and a lens 143 disposed above the LED 142. The lens 143 is accommodated within the lens housing 141. The light from the LED 142 is diffused through the lens 143 above, thereby forming a LED light effect having a wider angle.

An annular protrusion 145 is provided on a top edge of the lens 143, and an annular groove 146 and a buckle 147 corresponding to the annular protrusion 145 are provided inside the top of the lens housing 141. During assembling, there is only a need to correspondingly embed the annular protrusion 145 of the lens 143 into the annular groove 146 and the buckle 147 of the lens housing 141, so that the lens housing 141 can be snap-fitted and fixed to the lens 143. Next, the lens 143 are mounted on the LED 142.

In addition, a plurality of radiating fins 16 that are perpendicular to the lamp cover 15 are evenly arranged below the lamp housing 13, so as to ensure the heat dissipation effect of the hard linear lamp of the present utility model.

The second embodiment of the present utility model will be briefly described below.

Referring to FIG. 8, FIG. 8 is a schematic view of an exploded structure in a curved state according to a second embodiment of the present utility model. In the second embodiment, adjustments are made to an assembly accessory of the fastener 22 and the snap-fitting manner of the elastic piece 30 with the lamp housing 13, so that the hard linear lamp in the present utility model is also suitable for arc-shaped or irregular linear lamping occasions, and may meet different requirements in terms of cost and price as well as installation environment.
