[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] Reference Figures 1 to 3 In some embodiments of the first aspect of the present invention, a lamp end plug comprises an end plug body 100, a cavity 110 with an open end is provided inside the end plug body 100, an opening for connecting the outside with the inside is provided at the upper part of the cavity 110, a plug connector 120 is provided at both sides of the opening of the cavity 110, and the two plug connectors 120 extend in a direction toward the outside of the cavity 110. To facilitate the production of the end plug body 100, in some embodiments of the present invention, the end plug body 100 and the two plug connectors 120 are integrally injection molded, a light source 200 that can emit light when powered is provided in the cavity 110, and the light source 200 is inclined toward the end of the opening away from the plug connector 120 or the middle of the light source 200 toward the opening.

[0035] Since the end plug of the present invention is provided with a light source 200 installed in the cavity 110, the light source 200 is tilted toward the end of the upper opening of the cavity 110 away from the connector 120 or the light source 200 is toward the middle of the opening, by adopting the above structure, the light source 200 on the end plug can illuminate the end plug when powered on, thereby enabling the lamp using the end plug of the present invention to illuminate its end, thereby solving the technical problem of the existence of a dark brightness area at the end of the existing lamp when powered on, thereby meeting the needs of users.

[0036] Reference Figure 1 and Figure 3 In order to prevent the light source 200 from being exposed, in some embodiments of the present invention, a light-transmitting plate 130 is disposed at the opening of the upper portion of the cavity 110, and the light source 200 is tilted toward the end of the light-transmitting plate 130 away from the connector 120 or toward the middle of the light-transmitting plate 130. By adopting the above structure, when the light source 200 is powered on and emits light, the light can illuminate the end of the light-transmitting plate 130 away from the connector 120 or illuminate the middle of the light-transmitting plate 130, and then illuminate the end plug body 100, thereby preventing a dark area from appearing at the end of the end plug body 100 away from the connector 120.

[0037] Reference Figures 1 to 3 In order to facilitate the end plug to be better connected with the external light expansion plate (not shown in the figure), in some embodiments of the present invention, an upwardly extending mounting arm 140 is respectively provided on both sides of the upper part of the end plug body 100, and a mutually parallel mounting groove 141 is respectively provided on the inner walls on both sides of the two mounting arms 140. The two mounting grooves 141 are located above the light-transmitting plate 130, and the horizontal heights of the two mounting grooves 141 are the same. By adopting the above structure, the external light expansion plate can be embedded in the two mounting grooves 141, which is convenient for installation. At the same time, the light emitted by the light source 200 passes through the light-transmitting plate 130 and then irradiates the light expansion plate. Through the function of the light expansion plate, the light can be made softer to prevent glare.

[0038] In order to make the light emitted from the end plug softer, in some embodiments of the present invention, an uneven texture 131 is provided on the inner wall of the light-transmitting plate 130 facing the light source 200. By adopting the above structure, the light emitted by the light source 200 will be scattered when passing through the light-transmitting plate 130, thereby achieving a better diffusion effect of the light and preventing glare.

[0039] In order to facilitate the installation of the light source 200 in the cavity 110, in certain embodiments of the present invention, the inner bottom wall of the cavity 110 is a slope whose horizontal height gradually decreases along the direction away from the plug-in connector 120; the light source 200 includes a plate-shaped substrate 210 and a light-emitting chip 211 disposed on the substrate 210, and the substrate 210 is attached to the inner bottom wall of the cavity 110. Since the substrate 210 and the light-emitting chip 211 are conventional technologies in the art, they will not be described in detail. By adopting the above structure, when the substrate 210 is attached to the inner bottom wall of the cavity 110, the light-emitting chip 211 will be inclined toward the end of the light-transmitting plate 130 away from the plug-in connector 120, and then when the light-emitting chip 211 is powered on to emit light, the light can be better irradiated to the outer end of the light-transmitting plate 130 away from the plug-in connector 120, and then the end plug can be better illuminated.

[0040] In order to facilitate supplying power to the light source 200, the end plug of some embodiments of the present invention further includes two conductive contacts 300 for conducting electricity. The two conductive contacts 300 are respectively arranged on both sides of the light source 200 and extend outward in a direction away from the cavity 110. Two metal contacts 212 for conducting electricity are arranged on the surface of the substrate 210. The two conductive contacts 300 are in contact with the two metal contacts 212 in a one-to-one correspondence. By adopting the above structure, when the end plug is inserted into the lamp, the two conductive contacts 300 can contact the power supply circuit inside the lamp, and then the two conductive contacts 300 can conduct the electric energy to the two metal contacts 212. Finally, the two metal contacts 212 transfer the electric energy to the substrate 210 and the light-emitting chip 211. By adopting the above structure, the connection between the end plug and the power supply circuit can be simpler and faster.

[0041] In order to facilitate the positioning and installation of the two conductive contacts 300, in some embodiments of the present invention, the two conductive contacts 300 are respectively pressed against the inner side walls of the two plug connectors 120. By adopting the above structure, the positioning and installation of the two conductive contacts 300 are facilitated, and the two conductive contacts 300 can be prevented from being exposed or shifted, which can prevent leakage and make the connection between the two conductive contacts 300 and the power supply circuit more solid and reliable.

[0042] In order to facilitate the connection between the end plug of the present invention and the external connection piece (not shown in the figure), a downwardly extending clamp arm 150 is respectively provided on both sides of the bottom of the end plug body 100, and two conductive contact pieces 300 pass through the bottom of the end plug body 100 and abut against the inner side walls of the two clamp arms 150 one by one. Therefore, the external connection piece can be inserted between the two clamp arms 150, which is convenient for installation; if metal connection pieces for conduction (not shown in the figure) are provided on the outer walls of the two sides of the connection piece, the metal connection pieces on the outer walls of the two sides of the connection piece can contact the two conductive contact pieces 300 one by one, thereby facilitating the connection of the circuit, so that the external power supply circuit can supply power to the end plug or the end plug can supply power to the external electrical equipment.

[0043] Furthermore, in order to facilitate the installation of the end plug body 100 on the lamp, in some embodiments of the present invention, a mounting hole 160 arranged in a horizontal direction is provided at the middle position of the bottom of the end plug body 100. Therefore, when the end plug is inserted into the lamp, a bolt can be passed through the mounting hole 160 and connected to the lamp, and then the end plug can be locked on the lamp to prevent the end plug from accidentally detaching from the lamp, and the connection is firm and reliable.

[0044] Reference Figures 1 to 4A lamp according to some embodiments of the second aspect of the present invention comprises a lamp body 400, wherein an open lamp accommodating cavity 410 is provided inside the lamp body 400, and the above-mentioned lamp end plug is installed at the open portion of the lamp accommodating cavity 410.

[0045] The lamp of the present invention overcomes the technical problem that dark areas of brightness are easily generated at the ends of existing lamps by adopting the above-mentioned end plugs, which not only makes the lighting effect of the lamp better, but also prevents dark areas of brightness from appearing between two adjacent lamps connected in series.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
