The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described by referring to the drawings below are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0028] The present utility model relates to a strip light, which includes a lamp housing 100, a lamp board 200 and a power connection member 300.

[0029] Such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the lamp housing 100 is in a long strip shape. In the direction shown in the figure, the length direction of the lamp housing 100 is the left-right direction. A cavity 110 is formed inside the lamp housing 100, and the cavity 110 extends left and right along the length direction of the lamp housing 100. The cavity 110 opens on the upper side wall of the lamp housing 100 to form a light-transmitting opening 111. The light-transmitting opening 111 extends along the length direction of the lamp housing 100, and the lengths of the light-transmitting opening 111 and the cavity 110 can be equal. The cavity 110 penetrates through at least one end of the lamp housing 100 along the length direction, and the penetrated end forms a plug-in end 120. That is, it can be that the left end of the cavity 110 penetrates to the left end of the lamp housing 100, the left end of the lamp housing 100 forms a plug-in end 120, and the right end of the lamp housing 100 is closed; or it can be that the right end of the cavity 110 penetrates to the right end of the lamp housing 100, the left section of the lamp housing 100 is closed, and the right end of the lamp housing 100 forms a plug-in end 120; it can also be that the left and right ends of the cavity 110 respectively penetrate to the left and right ends of the lamp housing 100, and the left and right ends of the lamp housing 100 are respectively plug-in ends 120. The lamp board 200 is a circuit board, on which a light source body 210 and at least two conductive rails 220 are integrated. As Figure 3 shown, the light source body 210 can be an LED lamp bead; it can also be that, as Figure 6 shown, the light source body 210 can be an integrated strip-shaped COB light source. The conductive rail 220 can be composed of a copper strip or other metal strips that can conduct electricity. The conductive rail 220 is electrically connected to the light source body 210 through a power supply board. The lamp board 200 is installed in the cavity 110. Each conductive rail 220 is on the same side of the cavity 110 to achieve single-sided conduction. The electrical connection member 300 is provided with at least two conductive terminals 301. The conductive terminals 301 can be provided with elastic conductive ends. The number of conductive terminals 301 provided is the same as the number of conductive rails 220. In this embodiment, two conductive rails 220 are provided, one is the positive electrode and the other is the negative electrode. Two conductive terminals 301 are correspondingly provided on the electrical connection member 300. The shape of the electrical connection member 300 is adapted to the shape of the plug-in end 120. When the electrical connection member 300 is inserted into the plug-in end 120, the electrical connection member 300 can be integrally inserted into the cavity 110, and the conductive terminals 301 can be smoothly paired with each conductive rail 220 without being blocked. During use, an external power supply can be connected to the electrical connection member 300 through a wire, and the electrical connection member 300 is inserted into the plug-in end 120 for fixation. The conductive terminals 301 are in one-to-one pairing contact with the conductive rails 220. The external power supply supplies power to the lamp board 200 through the electrical connection member 300, the conductive rails 220, etc., and the light source body 210 is powered on to emit light, and the light irradiates outward through the light-transmitting opening 111. The use of the plug-in pairing of the electrical connection member 300 and the plug-in end 120 realizes quick loading and unloading, and at the same time, the pairing of the conductive terminals 301 and the conductive rails 220 is used for electrical connection, replacing the conventional structure of welding and leading out wires on the circuit board, and there is no need to worry about the problem that the welding position of the wire and the circuit board is in poor contact or disconnected and difficult to repair during use.

[0030] In some specific embodiments of the present utility model, the lamp board 200 is in the shape of a long strip. The lamp board 200 is fixed on a cavity wall of the cavity 110 along the length direction of the lamp housing 100. During installation, the lamp board 200 can extend into the cavity 110 from the insertion end 120, and then the lamp board 200 is fixed on the cavity wall of the cavity 110 by means of gluing or sticking. Each conductive rail 220 is parallel to each other, and the conductive rails 220 are distributed vertically on the lamp board 200. And each conductive rail 220 extends left and right on the lamp board 200 along the length direction. The two ends of the conductive rail 220 can extend to be flush with or close to the two ends of the lamp board 200. After installation, the end of the conductive rail 220 can be flush with or close to the end face of the insertion end 120. When the electrical connector is inserted into the insertion end 120, the conductive terminal 301 can be abutted against the end of the conductive rail 220. At the same time, the electrical connector can extend into the cavity 110 to different depths along the length direction of the lamp housing 100, and it can ensure that the conductive terminal 301 remains in contact with the conductive rail 220.

[0031] In this embodiment, the cavity 110 penetrates through both ends of the lamp housing 100, and the two ends of the lamp housing 100 respectively form the insertion ends 120. One of the insertion ends 120 can be connected to an external power source through the electrical connection member 300, and the other insertion end 120 can be connected to other electrical appliances or the insertion end 120 of another strip light through another electrical connection member 300, and the electrical connection members 300 installed on the insertion ends 120 at both ends of the same strip light are electrically conducted through the conductive rail 220.

[0032] Further, as Figure 1 and Figure 5 The cavity wall of the cavity 110 includes a first wall 112, a second wall 113 and a third wall 114. The second wall 113 and the third wall 114 are respectively formed by extending from the left and right sides of the first wall 112 in the same direction, and the first wall 112, the second wall 113 and the third wall 114 are distributed in a U shape. The first wall 112 is opposite to the light transmission opening 111, and the second wall 113 and the third wall 114 are opposite to each other. The lamp board 200 is fixed on the second wall 113, and each light source body 210 faces the third wall 114. A light guide bar 400 is installed at the light transmission opening 111. The light guide bar 400 is made of a light-transmissive material. The light guide bar 400 closes the light transmission opening 111. A plurality of light source bodies 210 are distributed on the lamp board 200 along the length direction of the lamp board 200. The light guide bar 400 can guide the light generated by the light source body 210 towards the light transmission opening 111. The light irradiates towards the third wall 114 direction, and then refracts and diffuses towards the light transmission opening 111 direction through the light guide bar 400, so that the light is more uniform when projected outwards, and the contour of the light source body 210 when emitting light cannot be seen through the light guide bar 400.

[0033] Specifically, as Figure 1 and Figure 5As shown in the figure, the light guide bar 400 includes a first light guide portion 410 and a second light guide portion 420 distributed in an L shape. That is, the cross-section of the light guide bar 400 in the up and down direction is L-shaped. The first light guide portion 410 is horizontally arranged, and the second light guide portion 420 is vertically arranged. The first light guide portion 410 is installed at the light transmission port 111 and is opposite to the first wall 112, and the first light guide portion 410 can close the light transmission port 111. The second light guide portion 420 is located in the cavity 110 and on the side where the third wall 114 is located. The light source body 210 is opposite to the second light guide portion 420. The light source body 210 is closer to the light guide bar 400 than the conductive rail 220. After the power connection member 300 is connected to the conductive rail 220, it will not block the light, so that there will be no dark area in the whole light guide bar 400 when the light passes through the light guide bar 400. The light mainly irradiates on the second light guide portion 420, and then refracts toward the first light guide portion 410 through the second light guide portion 420 and irradiates outward. Further, a first light blocking layer 430 is provided on the side surface of the first light guide portion 410 close to the second wall 113. The first light blocking layer 430 is attached to the second wall 113. A second light blocking layer 440 is provided on the side surface of the second light guide portion 420 close to the third wall 114. The second light blocking layer 440 extends to the side surface of the second light guide portion 420 opposite to the first wall 112. The part of the second light blocking layer 440 close to the third wall 114 is attached to the third wall 114. The first light blocking layer 430 and the second light blocking layer 440 are made of non-light-transmitting materials, and the first light blocking layer 430 and the second light blocking layer 440 are directly formed on the light guide bar 400. The light refracts through the first light blocking layer 430 and the second light blocking layer 440, and at the same time, it can prevent the light from leaking through the gaps between the conduit bar and the first wall 112 and the second wall 113.

[0034] Among them, as Figure 1 , Figure 2 and Figure 5 shown, first clamping bars 130 extending along the length direction are provided on both the second wall 113 and the third wall 114. Claw slots 450 extending along the length direction are provided on both the first light blocking layer 430 and the second light blocking layer 440. During installation, the light guide bar 400 is inserted into the light transmission port 111 from the insertion end 120, and the first clamping bars 130 and the claw slots 450 are slidably connected in a one-to-one correspondence. The installation of the light guide bar 400 is guided by the first clamping bars 130 and the claw slots 450, and at the same time, the light guide bar 400 is restricted from disengaging from the light transmission port 111 in the up and down direction. A second clamping bar 140 extending along the length direction is provided on the third wall 114. One side of the second light blocking layer 440 facing the first wall 112 abuts against the second clamping bar 140. The light guide bar 400 is further fixed by the second clamping bar 140. At the same time, the second clamping bar 140 is used to distinguish the second wall 113 and the third wall 114, so as to quickly identify and install the lamp board 200 on the second wall 113.

[0035] In some specific embodiments of the present invention, as Figure 4As shown, the power connection member 300 includes two connection portions 310. The connection portions 310 are adaptively plugged into the plug-in ends 120. At least two conductive terminals 301 are provided on each connection portion 310. The conductive terminals 301 on the two connection portions 310 are paired one by one and connected through wires. One connection portion 310 on the power connection member 300 can be connected to the plug-in end 120 of one linear lamp, and the other connection portion 310 can be connected to the plug-in end 120 of another linear lamp, so that the two linear lamps are electrically connected.
