The first channel 20 and the second channel 40 can connect two ends of the same light source 300 or different light sources to form a corner connection structure, so that light emitting body structures in different shapes can be obtained, and the structure is simple and convenient to use. Optionally, the light source 300 is a LED strip.

Furthermore, the connecting body 10 is provided with at least one first insertion hole 30 and at least one second insertion hole 50, each connecting terminal is respectively installed in a

corresponding insertion hole

30 or 50, and the paired first connecting terminals and second connecting terminals are connected into a whole. The connecting body 10 includes at least one first connecting portion 11 and at least one second connecting portion 12 connected at a corner, at least one first insertion hole 30 and at least one second insertion hole 50 are respectively disposed on the first connecting portion 11 and the second connecting portion 12, the first channel 20 and the second channel 40 are respectively disposed on the first connecting portion 11 and the second connecting portion 12, and a joint of the first connecting portion 11 and the second connecting portion 12 forms a corner, such as an acute angle, an obtuse angle or a right angle, which may be curved in practical application. Each of the first and

second insertion holes

30 and 50 communicates with the first and

second passages

20 and 40, respectively, so that both ends of the light source 300 installed in the two

passages

20 and 40 are electrically connected through the connection terminals in the first and

second insertion holes

30 and 50, respectively. A plurality of jacks are shown to ensure electrical connection. The connecting body 10 is preferably made of a transparent material, so that light emitted from the light source 300 can penetrate and irradiate the outside of the connecting body 10. Alternatively, the junction of the first connection portion 11 and the second connection portion 12 forms a right angle.

First passageway 20 includes a first open end 23, a first inner end 24, and first receiving portion 21 and first receiving portion 22 disposed between first open end 23 and second inner end 24. The first receiving portion 21 communicates with the first receiving portion 22. Second channel 40 includes a second open end 43, a second inner end 44, and a second receiving portion 41 and a second receiving portion 42 provided between second open end 43 and second inner end 44, second receiving portion 41 communicating with second receiving portion 42. The first and

second insertion holes

30 and 50 are respectively communicated with the first and second

accommodating portions

22 and 42. The first inner end 24 and the second inner end 44 are disposed adjacent to each other, so that two ends of the light source 300 or different light sources 300 are close to each other as much as possible, thereby enabling the light source 300 to emit light uniformly at the position of the adaptor connector 100, reducing a shadow region (a non-light-emitting region), and finally enabling the two ends of the light source 300 or different light sources 300 to be perfectly connected. To eliminate the possibility of shorting when the two ends of the light source 300 are inserted into the first inner end 24 and the second inner end 44 of the first channel 20 and the second channel 40, respectively, the first inner end 24 and the second inner end 24 are preferably closed ends.

Further, the first receiving portion 21 penetrates a surface of the connecting body 10 away from the first receiving portion 22, and the second receiving portion 41 penetrates a surface of the connecting body 10 away from the second receiving portion 42. Thus, the

first passages

20 and 40 are open slot shaped. Thus, in an alternative embodiment, the first channel 20 is substantially in the form of a T-shaped slot or a T-shaped cavity, such that the cross-sectional shape of the channel is identical to the cross-sectional shape of the end of the light strip to which it is to be connected. The second channel 40 is also generally in the form of a T-shaped channel or T-shaped cavity, such that the cross-sectional shape of the second channel 40 is consistent with the cross-sectional shape of the end of the light strip to which it is to be connected.

corresponding channel

20 and 40 so as to be communicated with a circuit on the lamp strip through the connecting terminal when the lamp strip is inserted. Specifically, each of the connection terminals is pointed at an end portion extending into the first receiving portion 22 and the second receiving portion 42 so as to pierce a conductive portion of the light source 300, thereby electrically connecting both ends of the light source 300.

Further, the connecting body 10 further comprises an insulation barrier 13 separating the first channel 20 and the second channel 40, at the junction of the two channels. Specifically, the insulation barrier 13 is provided between the first receiving part 22 and the second receiving part 41 to block both ends of the light source 300 or different light sources 300. The thickness of the insulation barrier 13 is small, so that two ends of the light source 300 or different light sources 300 are close to each other as much as possible, and shadow regions (non-light emitting regions) are reduced. Preferably, the thickness of insulation barrier 13 is between 0.1-0.5 cm.

As shown in fig. 6, the light source 300 is exemplified by a light strip, and includes a substrate 31, a light emitting portion 32 disposed on the substrate 31, a conductive portion 33 disposed on the substrate 31 and electrically connected to the light emitting portion 32, and a first light emitting end 34 and a second light emitting end 35 disposed at two ends of the substrate 31. The light emitting portion 32 is generally relatively convex from the substrate 31, and thus, the strip has a convex cross-section. That is, the light emitting portion 32 and both sides of the substrate 31 correspond to the

receiving portions

21, 41 and the receiving

portions

22, 42 of the two

channels

20, 40. When two ends of the light source 300 are connected to form a ring structure, the first light-emitting end 34 is inserted into the first opening end 23 of the first channel 20 and abuts against the first inner end 24, the substrate 31 of the light source 300 close to the first light-emitting end 34 is installed in the first accommodating portion 22, the light-emitting portion 32 is accommodated in the first accommodating portion 21, and the conductive portion 33 corresponds to the position where the first insertion holes 30 are communicated; then, the second light-emitting end 35 is inserted into the second opening end 43 of the second channel 40 and abuts against the second inner end 44, the light source 300 is mounted in the second accommodating portion 42 close to the substrate 31 of the second light-emitting end 35, the light-emitting portion 32 is accommodated in the second accommodating portion 42, and the conductive portion 33 corresponds to the position where the second insertion holes 50 communicate; finally, a plurality of connection terminals are disposed in the first and

second insertion holes

30 and 50, and the connection terminals located at the same side are connected to each other, so that the positive electrode of one end of the light source 300 is communicated with the positive electrode of the other end or the positive electrode of the other end of the light source, and the negative electrodes located at the two ends of the corner are also communicated, thereby electrically connecting the light source 300 at a predetermined angle or curvature, forming a detachable or curved light emitting band or an annular light emitting band, etc.

In order to improve the uniformity of the light emitted from the first and second light-

emitting ends

34 and 35 of the light source 300 at the first and second

inner ends

24 and 44, the first inner end 24 is disposed such that the projection of the first inner end 24 onto the second inner end 44 falls between the range D of the center and the edge of the second inner end 44, so that the light-emitting portion 32 close to the first light-emitting end 34 and the light-emitting portion 32 close to the second light-emitting end 35 are opposite to each other in the range D, and thus, the light emitted from the light-emitting portions 32 close to the first and second light-emitting

ends

34 and 35 of the light source 34 in the corner connector 100 can be prevented from being interrupted or discontinuous. Thus, when the two ends of the light source 300 are inserted into the two

passages

20 and 40, the light emitting chips in the last light emitting part 32 at the two ends can be regarded as the normal interval of the adjacent chips on the same lamp strip, and the occurrence of the light emitting blind area or the shadow can be successfully eliminated.

In another aspect of the embodiments of the present invention, there is also provided a lighting device, which includes at least one light strip, each light strip is used as a strip-shaped light source, that is, the light source 300 is as described above, as shown in fig. 6, each light strip 300 has two ends, at least one of the two ends of the light strip 300 is electrically connected through the corner connector 100 as described above, so that the light strips are connected into a whole, and thus the lighting device or the lighting strip is made by the curve or the folding line which forms an integral corner. In a specific application, the plurality of lamp strips may be electrically connected in sequence through the corner connector 100, so as to extend the light emitting length. Moreover, the angle of the corner can be set according to the requirement, and the corner connector 100 is electrically connected, so that the continuity of circuit connection is ensured, and the light source with the required zigzag shape can be combined to form various light-emitting devices.

Fig. 4 and 5 show a second embodiment of the corner connector 200 of the present invention, which is different from the first embodiment mainly in that the first channel 20 ' of the second embodiment is communicated with the second channel 40 ', and the first receiving portion 21 ' and the second receiving portion 41 ' are communicated with the surface of the body 10 ', that is, the first channel 20 ' and the second channel 40 ' are slotted.

Referring to fig. 4 to 6 together, specifically, the first receiving portion 21 'and the second receiving portion 41', and the first receiving portion 22 'and the second receiving portion 42' are all communicated at a connection portion (i.e., a corner) of the first connection portion 11 'and the second connection portion 12', and meanwhile, the first receiving portion 21 'penetrates through a surface of the connection body 10' away from the first receiving portion 22 ', and the second receiving portion 41' penetrates through a surface of the connection body 10 'away from the second receiving portion 42'. When the first and second light emitting ends 34 and 35 of the light source 300 are mounted in the first and second channels 20 'and 40', the second light emitting end 35 abuts against the substrate 31 near the first light emitting end 34, and the light emitting portion 32 is exposed from the first and second connection portions 11 'and 12'.

That is, compared to the first embodiment, the insulation barrier 13 is omitted between the first light emitting end 34 and the second light emitting end 35, so that the first light emitting end 34 and the second light emitting end 35 are closer to each other, and the emitted light is better connected. In addition, because the light emitting part 32 is directly exposed out of the first connecting part 11 'and the second connecting part 12', the light emitted by the light emitting part 32 at the corner connector 200 is not blocked, the brightness is consistent with that of other places, and the display effect is good. The material of the connecting body 10' does not need to be permeable, and other materials can be used, so that the limitation on the production of the corner connector 200 is reduced; the connecting body 10 'can be made of various materials (such as iron and rubber), so that the connecting body 10' has different hardness and rigidity, and a user can select the connecting body according to the use requirement, thereby increasing the selectivity of the corner connector 200.

In another alternative embodiment, the first channel 20 and the second channel 40 or the first channel 20 'and the second channel 40' are arranged to intersect at the adjacent position, such as an overpass structure. Taking the shape of fig. 3 as an example, the first inner end 24 is tilted upward, and the second inner end 44 is penetrated by the bottom wall of the first passage 20 but not penetrated by the first passage 20. Specifically, the bottom surface of the first channel 20 is sloped, i.e., the bottom surface rises diagonally from the first open end 23 to the first inner end 24. The bottom wall of the first channel 20 is dug with an empty groove at the extending position of the second channel 40, so that the second inner end 44 extends into the empty groove of the first channel 20 and extends to the side of the first channel 20 far away from the second inner end 44, and a three-dimensional crossing structure is formed. Of course, the channel 40 may be an obliquely upward channel, and is not limited thereto.

It can be seen that the corner connectors (100, 200) and the light emitting device are arranged in the first channels (20, 20 ') and the second channels (40, 40') of the corners, so that two ends of the same light source 300 are respectively arranged in the first channels (20, 20 ') and the second channels (40, 40') to form a ring-shaped light emitting body, or the ends of different light sources 300 are respectively arranged in the first channels (20, 20 ') and the second channels (40, 40') to connect the different light sources 300 in an angled or arc manner, and because the adjacent positions of the two ends of the light sources are close enough, the light emitting blind area or shadow at the corner connecting position is effectively avoided, and the light emitting is continuous when the zigzag light emitting strip is manufactured, the light emitting effect is unexpectedly good, the structure is simple, and the use is convenient.

It should be noted that the present invention is not limited to the above embodiments, and other changes can be made by those skilled in the art according to the spirit of the present invention, and all the changes made according to the spirit of the present invention should be included in the scope of the present invention.
