  • The lamp housing 101 is arranged on the strip lamp holder 100 and extends along the length direction. The lamp cavity 101 is used to accommodate the light-emitting circuit board 200, which can be formed by buckling with the strip lamp holder 100 through an optical element (such as a lampshade). The buckle needs to be sealed. This is not redundant in the prior art, and it can also be integrally formed. In this embodiment, the lamp housing 101 is made of transparent material, which is generally made of transparent plastic, which reduces assembly and sealing materials and has better sealing effect. At least one end of the lamp housing 101 is provided with a mounting opening 102, or both ends can be provided with a mounting opening 102, and the other end can also be encapsulated by the waterproof lamp cap 300 of the present embodiment, or by the prior art, which will not be repeated.
  • The light-emitting circuit board 200 is arranged in the lamp housing 101, which is provided with a light-emitting module, and the light-emitting module can adopt an LED chip. This is not repeated since it is in the prior art. One end of the light-emitting circuit board 200 is provided with a first electrical connection member/connector 201, which is close to the mounting opening 102.
  • The waterproof light holder 300 is arranged on the mounting opening 102, and the waterproof lamp holder 300 includes an end cover 301, a plug connector 302 and an electrical connection assembly 304. The waterproof lamp holder 300 is used to encapsulate the mounting opening 102 and is provided with an external member/connector 3041 to connect the external power supply. The end cover 301 is arranged on the mounting opening 102 with a plug hole 3011. It is generally fixed outside the mounting opening 102 and sometimes partially extends into the mounting opening 102. The end cover 301 is fixedly connected with the strip lamp holder 100. In this embodiment, it is fixedly connected by screws 3012. The plug connector 302 is used to set the second electrical connection member 3042 to be electrically connected with the light-emitting circuit board 200, the root/connection structure 3021 of the plug connector 302 is fixedly connected with the inner 3012 of the end cover 301, the body extends into the light housing 101, and a first waterproof structure 303 is arranged between the body and the inner wall of the light housing 102. The first waterproof structure 303 can be a solid elastic seal, such as a sealing ring, etc., In order to improve the waterproof grade, the sealing and waterproof can also be realized by using the glue injection/filling cavity. In this example, the first waterproof structure 303 includes a front baffle 3031 and a rear baffle 3032; the front baffle 3031 is arranged on the plug connector 302; the rear baffle 3032 is spaced from the front baffle 3031 to form a first glue filling cavity 3033 between the plug 302 and the inner wall of the lamp cavity 102, and the first glue filling cavity 3033 is provided with a glue injection hole 3034. The glue injection hole 3034 is arranged on the lamp cavity 101.
  • The electrical connection assembly 304 includes an external member/connector 3041 arranged on the insertion hole 3011, a second electrical connection member/connector 3042 arranged on the plug 302 elastically against the first electrical connection member 201 to realize electrical connection, and a conductive member 3043 connecting the external connector 3041 and the second electrical connector 3042. The conductive member 3043 passes through the plug 302 and seals the passage 3022 through the second waterproof structure 305. The electrical connection assembly 304 is generally an integral part, so assembly needs to be considered. The external connector 3041 may extend out of the end cover 300 through the insertion hole 3011 with a wire, or may be arranged inside the end cover 300 in the form of a socket. In this embodiment, the external connector 3041 is a socket, and the socket is arranged on the insertion hole 3011.
  • In order to reduce the amount of glue, a connecting column 3133 is arranged between the front baffle 3031 and the rear baffle 3032. The outer contour of the connecting column 3133 is smaller than the inner contour of the cross section of the lamp housing 101, so as to make the first glue filling cavity 3033 into a ring and reduce the amount of glue.
  • Meanwhile, the plug connector 302 is provided with the second waterproof structure 305 on the outside of the rear baffle 3032. Specifically, the second waterproof structure 305 is a second glue filling cavity 3051 surrounding the channel 3022. In order to facilitate glue injection, the second glue filling cavity 3051 is connected with the first glue filling cavity 3033.
  • In order to facilitate manufacturing and installation, in this embodiment, the first waterproof structure 303 can be divided into an upper part 3035 fixedly connected with the plug connector 302 and a lower part 3036 detachably connected with the upper part 3035 in a direction perpendicular to the length of the strip light holder 100. This facilitates the installation of the electrical connection assembly 304. The upper part 3035 and the lower part 3036 are provided with the channel 3022 at the connection. When the upper 3035 and the lower 3036 part are separated, it is convenient to install the electrical connection assembly 304. After installation, the upper 3035 and the lower 3036 part are spliced together to complete the fixation
  • The electrical connection component is 304 fixed on the upper part 3035 and then the lower 3036 and the upper 3035 part are assembled to fix the electrical connection assembly 304. At the same time, the lower 3036 is also matched with the upper 3035 to form the front and rear glue filling cavities. After the front and rear glue injection cavities are filled with glue, the waterproof effect can be better improved. Finally, the plug connector 302 is assembled with the end cover 301 to form a waterproof lamp holder/cap 300, The waterproof lamp holder 300 can save the trouble of manual wire welding and realize automatic assembly.
  • The second electrical connection member 3042 and the first electrical connection/connector 201 of the invention realize electrical connection through elastic butting. The first electrical connection 201 of the embodiment is provided with a conductive area 2011, and the second electrical connector 3042 is a spring piece butting with the conductive area 2011. The conductive area 2011 is a conductive sheet or metal foil. In addition to the cooperation between the elastic sheet and the conductive area 2011, it can also be connected by means of a pin and a conductive pinhole. This is the prior art to realize plug-in electrical connection, which is not repeated in the present invention. Generally, the electrical connection is divided into positive and negative electrodes. Therefore, the second electrical connection member 3042 of this embodiment is provided with two side-by-side, which are positive and negative electrodes respectively. The conductive member 3043 can adopt a conductor, which can also be divided into positive and negative conductors.
  • As shown in FIGS. 6 and 7, in addition to being sealed in the above manner, the second waterproof structure 305 can also be directly realized by integral molding. In another embodiment, the plug connector 302 is integrally injection molded with the electrical connection assembly 304. Further, the plug connector 302 and the first waterproof structure 303 are integrally injection molded with the electrical connection assembly 304. The second waterproof structure 305 is the plug connector 302 body, so only the first waterproof structure 303 needs to be set, and the overall structure is simpler. However, the above process cost is high, and it is not applicable to the electrical connection assembly 304 with too long electrical connection assembly 3043. In the actual installation, the plug- connector 302 of this embodiment is set separately, the mounting part 3023 fixing the second electrical connection member 3042 is detachably connected with the main body of the plug connector 302.
  • The above is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modification, equivalent replacement or improvement within the spirit of the present invention, etc., is covered by the scope of the claims of the present invention.
