Referring to fig. 1 and 2, a bar lamp, which may be an LED bar lamp or other types of bar lamps, is provided in the embodiments of the present application. The bar lamp includes a lamp body assembly 10 and a base 20. The base 20 is a conductor, a first insulating layer (not shown) is disposed on a surface of the base 20, and the base 20 includes a first sidewall 21. The lamp body assembly 10 includes a lamp body 11, the lamp body 11 is a conductor, a second insulating layer (not shown) is disposed on a surface of the lamp body 11, and the lamp body 11 includes a second sidewall 111. The base 20 or the lamp body 11 is set to be grounded.

With reference to fig. 3 and 4, the first sidewall 21 is provided with first conductive pointed teeth 25, and the first conductive pointed teeth 25 are electrically connected to the first sidewall 21. When the lamp body 11 is mounted on the base 20, the first sidewall 21 and the second sidewall 111 are disposed correspondingly, and the first conductive pointed teeth 25 can scrape the second insulating layer and abut against the second sidewall 111, so that the first conductive pointed teeth 25 are electrically connected to the second sidewall 111.

It is understood that in another embodiment, the position of the conductive tines is changed, that is, the second conductive tines (not shown) are disposed on the second sidewall 111, and the second conductive tines are electrically connected to the second sidewall 111; when the lamp body 11 is mounted on the base 20, the first sidewall 21 and the second sidewall 111 are disposed correspondingly, and the second conductive pointed teeth can scrape the first insulating layer and abut against the first sidewall 21, so that the second conductive pointed teeth are electrically connected to the first sidewall 21.

Compared with the related art, in the strip lamp provided by the application, the base 20 and the lamp body 11 are both conductors, and the first side wall 21 of the base 20 corresponds to the second side wall 111 of the lamp body 11. There are two ways to achieve conduction between the lamp body 11 and the base 20 when the lamp body 11 is mounted on the base 20. One way is that: the first conductive pointed teeth 25 are disposed on the first sidewall 21, and when the lamp body 11 is mounted on the base 20, the second insulating layer on the second sidewall 111 is scraped by the first conductive pointed teeth 25, so that the first conductive pointed teeth 25 abut against the second sidewall 111 and are electrically connected. The other mode is as follows: the second conductive pointed teeth are disposed on the second sidewall 111, and when the lamp body 11 is mounted on the base 20, the first insulating layer on the first sidewall 21 is scraped by the second conductive pointed teeth, so that the second conductive pointed teeth abut against the first sidewall 21 and are electrically connected to the first sidewall 21. The conductive sharp teeth are arranged to achieve the effect of conducting the base 20 and the lamp body 11, one of the base 20 and the lamp body 11 is grounded, and the other is grounded, so that the base 20 and the lamp body 11 can be assembled and disassembled conveniently. The lamp body does not need to be subjected to anti-coating treatment like a conventional strip lamp, so that the traditional surface anti-coating treatment is optimized, and the process of connecting and conducting the lamp body 11 and the base 20 through a lead is not needed.

In the bar lamp, the base 20 and the lamp body 11 are both bar-shaped. Illustratively, the base 20 is a housing in the shape of a rectangular parallelepiped, and the base 20 has a placing cavity and a mounting opening 22 communicated with the placing cavity, and the placing cavity can be used for placing relevant devices of the strip lamp, such as a circuit control board.

The lamp main part 11 is as the carrier of light source subassembly 30, if LED bar lamp, light source subassembly 30 can be the form that sets up LED lamp pearl on the base plate 31 of rectangular shape, and base plate 31 installs on lamp main part 11.

The base 20 and the lamp body 11 are generally made of metal. The first insulating layer and the second insulating layer may be formed by surface treatment such as powder spraying or paint baking so that the surface of the lamp body 11 as a conductor is insulated from the surface of the base 20.

Referring to fig. 3 and 4, in another embodiment of the present application, when the first conductive tine 25 is disposed on the first sidewall 21, the first conductive tine 25 includes a first cantilever 251 connected to the first sidewall 21 and a first tine 252 bent and extended from an end of the first cantilever 251, and the first tine 252 is disposed toward the second sidewall 111. When the lamp body 11 is mounted on the base 20, the first pointed tooth portion 252 will have a relative displacement with respect to the second sidewall 111, and will scrape the second insulating layer and abut on the second sidewall 111. The first cantilever 251 has a certain elasticity, and during the process of mounting the lamp body 11 to the base 20, the first cantilever 251 is elastically deformed to reduce the resistance between the first pointed tooth portion 252 and the second sidewall 111, which facilitates the mounting of the lamp body 11 to the base 20. Meanwhile, the first pointed tooth 252 at the end of the first cantilever 251 reliably abuts against the second sidewall 111, so that the lamp body 11 and the base 20 are well conducted. Illustratively, the edge of the first sidewall 21 is provided with a notch 211, and the first suspension 251 is connected to the inner edge of the notch 211, so that the size of the first sidewall 21 in the height direction is small, and the first sidewall 21 in the height direction is in the up-down direction in fig. 3. Specifically, a plurality of first pointed teeth 252 may be disposed at the end of the first cantilever 251 to enhance the effect of the first pointed teeth 252 scraping the second insulation layer. Illustratively, the first tine 252 has a triangular shape, which is easily stamped and formed, and the tip of the tine can scrape the insulation layer and rest against the sidewall.

When the first conductive sharp teeth 25 are disposed on the first sidewall 21, the second sidewall 111 includes a second vertical wall 1111 and a second bent wall 1112, the second bent wall 1112 is formed by bending and extending an edge of the second vertical wall 1111, and a second assembling area 1113 is formed between the second vertical wall 1111 and the second bent wall 1112; when the lamp body 11 is mounted on the base 20, at least a portion of the first sidewall 21 extends into the second mounting region 1113, the first sidewall 21 faces the second vertical wall 1111, and the end edge of the first sidewall 21 abuts against the second bent wall 1112. When the lamp body 11 is mounted on the base 20, the end edge of the first side wall 21 supports the second bending wall 1112, thereby limiting the lamp body 11 on the base 20. Moreover, the first conductive pointed teeth 25 can scrape the second insulating layer on the second vertical wall 1111 and abut against the second vertical wall 1111, so that the conductive member is conducted with the lamp body 11.

In another embodiment of the present application, when the second conductive tine is disposed on the second sidewall 111, the second conductive tine includes a second cantilever (not shown) connected to the second sidewall 111 and a second tine portion (not shown) formed by bending and extending an end of the second cantilever, and the second tine portion is disposed toward the first sidewall 21. When the lamp body 11 is mounted on the base 20, the second pointed tooth part will be displaced relative to the first sidewall 21, scraping the first insulating layer and abutting on the first sidewall 21. The second cantilever has a certain elasticity, and during the process of mounting the lamp body 11 to the base 20, the second cantilever will be elastically deformed, reducing the resistance between the second pointed tooth portion and the first side wall 21, which facilitates the mounting of the lamp body 11 to the base 20. Meanwhile, the second pointed tooth part at the end of the second cantilever will reliably abut against the first sidewall 21, and good conduction between the lamp body 11 and the base 20 is realized. Illustratively, the edge of the second sidewall 111 is provided with a notch, and the second cantilever is connected to the inner edge of the notch, so that the second sidewall 111 has a smaller dimension in the height direction. Specifically, the second cantilever end can be provided with a plurality of second pointed teeth so as to enhance the effect of the second pointed teeth on scraping the first insulating layer. Illustratively, the second pointed tooth is triangular, which is easily stamped and formed, and the pointed end of the pointed tooth can scrape the insulating layer and abut against the side wall.

When the second sidewall 111 is provided with the second conductive sharp teeth, the first sidewall 21 includes a first vertical wall (not shown) and a first bent wall (not shown), the first bent wall is formed by bending and extending an edge of the first vertical wall, and a first assembling area is formed between the first vertical wall and the first bent wall; when the lamp body 11 is mounted on the base 20, at least a portion of the second sidewall 111 extends into the first mounting region, the second sidewall 111 faces the first vertical wall, and the end edge of the second sidewall 111 abuts against the first bent wall. When the lamp body 11 is mounted on the base 20, the first bent wall supports the end edge of the second sidewall 111, thereby limiting the lamp body 11 on the base 20. Moreover, the second conductive pointed teeth can scrape the first insulating layer on the first vertical wall and abut against the first vertical wall, so that the conductive piece is conducted with the lamp body 11.

Referring to fig. 5, in another embodiment of the present application, the number of the first sidewalls 21 is two, two first sidewalls 21 are disposed at intervals, a mounting opening 22 is formed between the two first sidewalls 21, and the first sidewalls 21 are sidewalls of the base 20 in the length direction of the strip lamp. The number of the second side walls 111 is two, two second side walls 111 are arranged at intervals, and the second side walls 111 are the side walls of the lamp body 11 in the length direction of the strip-shaped lamp. When the lamp body 11 is mounted on the base 20, the two second sidewalls 111 are respectively located at the outer side surfaces of the two first sidewalls 21, and the lamp body 11 is covered on the mounting opening 22, so that the lamp body 11 can be limited on the base 20.

Referring to fig. 5, in another embodiment of the present application, the first sidewall 21 is provided with a first buckle, the second sidewall 111 is provided with a second buckle 113 matched with the first buckle in a clamping manner, and the second buckle 113 is clamped to the first buckle so as to mount the lamp body 11 on the base 20. By adopting the mode, the lamp body 11 and the base 20 can be quickly assembled and disassembled, the operation is convenient, and in the process of installing the lamp body 11 on the base 20, the second sharp teeth scrape the corresponding insulating layer and abut against the side wall. Specifically, the two sides of the base 20 are provided with first buckles extending outwards, the two side edges of the lamp body 11 are provided with second buckles 113 extending inwards, the lamp body 11 provided with the end cover is assembled to the mounting port 22 of the base 20, the first buckles are connected with the second buckles 113 in a clamping mode, and reliable assembly of the lamp body 11 and the base 20 can be achieved. The disassembly process is also convenient to operate. The first buckle of the base 20 is a plurality of protruding structures protruding from two sides of the base 20, and the second buckle 113 of the lamp body 11 is disposed on the entire edge of the lamp body 11, so that the lamp body 11 can be reliably connected to the base 20 in the length direction when the second buckle 113 is fastened to the first buckle.

Referring to fig. 5, in another embodiment of the present application, the strip lamp includes a lamp body assembly 10 and a base 20. The end of the base 20 has a baffle 23. The lamp body assembly 10 includes a lamp body 11, a lamp cover 12, and an end cap 13. The lampshade 12 is installed on the lamp body 11, the lampshade 12 and the lamp body 11 enclose to form a containing cavity, and with reference to fig. 6, openings 121 communicated with the containing cavity are formed in two ends of the lampshade 12. With reference to fig. 8, the end cap 13 has a first surface 13a and a second surface 13b opposite to each other, and the first surface 13a is provided with a positioning structure for positioning and assembling with an end portion of the lamp housing 12 or an end portion of the lamp body 11; the second face 13b is provided with a step groove 131, and the step groove 131 can be understood as a groove of a step-like shape. With reference to fig. 5, 6, and 10, when the end cap 13 is mounted at the opening 121 and the lamp body 11 is mounted on the base 20, the baffle plate 23 can extend into the stepped groove 131 to limit the end cap 13 at the opening 121 along the normal direction of the opening 121, where the normal direction of the opening 121 can be understood as the direction perpendicular to the plane of the opening 121.

Referring to fig. 6, when the end cap 13 is mounted to the opening 121 of the end portion of the lamp housing 12, the end cap 13 is mounted and positioned to the end portion of the lamp housing 12 or the end portion of the lamp body 11 through the positioning structure, and with reference to fig. 5, the lamp body 11 mounted with the end cap 13 is mounted to the base 20, wherein the baffle 23 at the end portion of the base 20 extends into the step groove 131 of the end cap 13, so that the end cap 13 is limited at the opening 121 along the normal direction of the opening 121 of the lamp housing 12, the end cap 13 will not separate from the end portion of the lamp housing 12, and the mounted end cap 13 is stable and. Referring to fig. 5, when the end cap 13 needs to be removed, the lamp body 11 is separated from the base 20, and then the end cap 13 is separated from the end of the lamp housing 12 in combination with fig. 6. The assembly and disassembly operations among the base 20, the lamp body 11 and the end cover 13 are convenient and quick, the production cost is reduced, the production efficiency is improved, and the assembly and disassembly of the end cover 13 are not required to be realized by means of tools and screws as in the existing strip-shaped lamp.

Referring to fig. 2, in the bar lamp, a lamp housing 12 is in the shape of a bar. The lampshade 12 is made of transparent material and is light-permeable. The lamp housing 12 covers the outside of the light source assembly 30 to protect the light source assembly 30. Illustratively, the lamp housing 12 is a semi-cylindrical housing, and the semi-cylindrical lamp housing 12 can generate a relatively uniform light effect when the light source assembly 30 emits light. It can be understood that the openings 121 are formed at both ends of the lampshade 12, the end covers 13 are mounted at both ends of the lampshade 12, and the two end covers 13 are respectively assembled in a limiting manner through the two baffle plates 23.

Referring to fig. 8 (b), in another embodiment of the present application, the step groove 131 has a step surface 131a and a step side surface 131b, the step surface 131a refers to a surface parallel to the second surface 13b, and the step side surface 131b refers to a surface perpendicular to the second surface 13 b. Referring to fig. 5 and 9, when the end cap 13 is mounted to the opening 121 and the lamp body 11 is mounted to the base 20, the step surface 131a of the step groove 131 is flush with the end surface of the lamp body 11, the baffle plate 23 is attached to the step surface 131a of the step groove 131 and the end surface of the lamp body 11, and referring to fig. 10, the edge 23a of the baffle plate 23 is attached to the step side surface 131b of the step groove 131. By attaching the shutter 23 to the stepped surface 131a of the stepped groove 131 and the end surface of the lamp body 11, the shutter 23 blocks the end cap 13 completely in the normal direction of the opening 121 of the lamp housing 12, and movement of the end cap 13 in the normal direction of the opening 121 is restricted. By fitting the edge 23a of the shutter 23 to the stepped side surface 131b of the stepped groove 131, the end cap 13 is completely restrained in a plane perpendicular to the normal direction of the opening 121 of the lamp housing 12. Even if external force acts on the bar lamp, the end cap 13 is reliably fixed at the opening 121 of the lamp housing 12, reducing the possibility that the end cap 13 is separated from the opening 121. It can be understood that the inner side surface of the baffle 23 is not attached to the step surface 131a of the step groove 131 and the end surface of the lamp body 11 but has a certain distance, and the edge of the baffle 23 is not attached to the step side surface 131b of the step groove 131, so that the baffle 23 can limit the end cover 13.

As shown in fig. 11, fig. 11 shows a structure of a bar-type lamp in the related art. The light source assembly 30 'is disposed at the middle position of the surface of the lamp body 11', and two sides of the lamp body 11 'are planes parallel to the light emitting surface of the light source assembly 30'. The light emission angle β of the light source module 30' is about 120 °, and a region in the middle portion is defined as a light source beam region a, and a region other than this region is defined as a non-light source beam region B. When the light source assembly 30 ' emits light, the light source beam area a is light directly emitted from the light source assembly 30 ', the intensity of the light is relatively high, and the effect presented on the lamp shade 12 ' is relatively bright. The non-light source light beam region B needs to be illuminated by the light reflected from the inner wall of the lamp housing 12', and the intensity of the light is less than that of the light source light beam region a. Therefore, the conventional strip lamp has a light emitting effect that the middle of the light emitting surface of the lampshade 12' is slightly bright, the two sides of the light emitting surface are slightly dark, and the light emitting surface is uneven in brightness.

To solve the above problem, referring to fig. 7 and 12, the lamp body 11 includes a supporting wall 114 and an inclined wall 115 connected to two opposite sides of the supporting wall 114, and the supporting wall 114 and the inclined wall 115 enclose an installation cavity. Opposite sides of the lamp housing 12 are connected to inclined walls 115 located at opposite sides of the supporting wall 114. The light source assembly 30 is mounted on the support wall 114 with the light-emitting side of the light source assembly 30 disposed facing the lamp housing 12. The included angle α between the inclined walls 115 at opposite sides of the supporting wall 114 is smaller than or equal to the light-emitting angle β of the light source assembly 30, and the light-emitting angle β of the light source assembly 30 is the angle formed between the two side edges of the light beam emitted from the light source assembly 30. Because the included angle α formed by the inclined walls 115 on the two opposite sides of the supporting wall 114 is smaller than or equal to the light-emitting angle β of the light source assembly 30, most of the light generated by the light source assembly 30 can directly irradiate the lampshade 12, and the dark area is greatly reduced, so that a relatively uniform light-emitting effect is obtained, and the conditions that the middle of the light-emitting surface of the conventional strip-shaped lamp lampshade is slightly bright and the light and the shade on the two sides are not uniform are overcome.

Comparing the conventional bar lamp shown in fig. 11 and the bar lamp of the present application shown in fig. 12, both of them adopt a light source module with a light emitting angle β of 120 ° and a lamp shade with the same size, a light source beam region a of the lamp shade 12 irradiated by a light beam of the light source module 30 shown in fig. 12 is larger than a light source beam region a of the lamp shade 12 'irradiated by a light beam of the light source module 30' shown in fig. 11, and a non-light source beam region B is greatly reduced. It can be understood that, when the included angle α between the inclined walls 115 located at two opposite sides of the supporting wall 114 is smaller, the range of the light source assembly 30 irradiating the lampshade 12 is larger, the dark area of the light emitting surface is smaller, and the light emitting effect is more uniform.

When the included angle α is reduced to a value where the edges of the two sides of the light beam intersect with the end of the inclined wall 115, the included angle is called a critical angle, the light source light beam area a of the strip lamp is the largest, the light emitting area dark area is the smallest, and the light distribution angle of the whole lamp remains unchanged.

When the angle α between the inclined walls 115 located on opposite sides of the supporting wall 114 is smaller than the critical angle, such as the embodiment shown in fig. 13, the angle α is 80 °. The light source assembly 30 emits light beams with two side edges onto the inclined walls 115 of the lamp body 11, and the light beams will strike the lamp housing 12 along the included angle α between the inclined walls 115. The light-emitting angle of the whole lamp can be changed due to the change of the included angle alpha of the inclined walls 115 at the two sides, so that the light distribution angle of the whole lamp is changed. And when the included angle alpha is smaller than the critical angle, the smaller the included angle is, the smaller the light distribution angle of the whole lamp can be synchronously reduced.

Illustratively, the two opposite sides of the supporting wall 114 are respectively connected with an inclined wall 115, so that the structure having one supporting wall 114 and two inclined walls 115 is easily formed. The light source assembly 30 has a light emitting angle β ranging from 115 ° to 125 °, that is, the light source has a light emitting angle β of about 120 °, which is determined by the LED lamp bead 32 of the light source assembly 30. Illustratively, the light emission angle β of the light source assembly 30 is 119 °, 120 °, or 121 °.

Referring to fig. 7 and 12, in another embodiment of the present application, a light source assembly 30 includes a substrate 31 and a bead 32 disposed on a surface of the substrate 31, wherein the substrate 31 is disposed on a supporting wall 114. The lamp beads 32 are provided on the substrate 31, and the substrate 31 having the lamp beads 32 is assembled to the support wall 114, thus facilitating the assembly of the light source assembly 30. And the substrate 31 can radiate the light-emitting lamp bead 32, so that the heat generated by the lamp bead 32 is transmitted to the lamp body 11 through the substrate 31. The substrate 31 can be fitted into the card slot 112 through the port 112 a. This can reliably fix the substrate 31 to the lamp body 11, and reduce the possibility that the substrate 31 separates from the lamp body 11 by an external force. The card slot 112 has two facing recesses 112 b. The connection between the inclined wall 115 and the support wall 114 is provided with a protruding edge 116, and a groove 112b is formed between the protruding edge 116 and the support wall 114. During assembly, the substrate 31 is pushed into the card slot 112 through the port 112a, and two opposite edges of the substrate 31 enter the two grooves 112b respectively, so that the substrate 31 is limited on the lamp body 11.

The inclined walls 115 on the two opposite sides of the supporting wall 114 are symmetrically distributed relative to the supporting wall 114, the lamp beads 32 are linearly distributed, and the straight lines where the lamp beads 32 are located in the middle of the supporting wall 114. The inclined wall 115 of symmetric distribution, the cooperation sets up lamp pearl 32 in the middle of supporting wall 114, and the light that lamp pearl 32 produced most can directly see through lamp shade 12 like this, and the dark space on the lamp shade 12 can be few to obtain more even light-emitting effect.

Referring to fig. 7 and 12, in another embodiment of the present application, inward flanges 122 are formed on two opposite sides of the lamp housing 12 in an extending manner, an assembling groove 117 is formed at the end of the inclined wall 115, and the inward flanges 122 can be clamped in the assembling groove 117 to limit the lamp housing 12 on the lamp body 11. With this arrangement, the inward flange 122 of the lamp cover 12 is easily engaged with the fitting groove 117 of the inclined wall 115, and the lamp cover 12 is fitted to the lamp main body 11.
