DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.
[0017] Examples of the described embodiments are shown in the accompanying drawings, wherein like or similar designations refer to like or similar elements or components throughout. The embodiments described below are exemplary and are intended to be illustrative of the present application and are not to be understood as limiting the present application.
[0018] Referring to Figures 1-3 A heat-dissipating direct-inserted lamp bead comprises a lampwick body 2, a lampwick mounting seat 3, a pin assembly, a transparent plastic cover 1 and a heat-dissipating assembly. The lampwick mounting seat 3 is a plastic cylinder. The lampwick mounting seat 3 is provided with a lampwick clamping groove 31 at the top. The pin assembly comprises two pin rods 7 and an abutting gasket 72. The two pin rods 7 are inserted into the bottom of the lampwick clamping groove 31 from the bottom of the lampwick mounting seat 3. The abutting gasket 72 is fixed on the top of the pin rods 7 and exposed at the bottom of the lampwick clamping groove 31. The heat-dissipating assembly comprises a metal sleeve 4, a metal ring base 5 and heat-dissipating fins 6. The bottom of the metal sleeve 4 is fixedly connected with the upper surface of the metal ring base 5. The inner wall of the metal sleeve 4 is matched and connected with the inner wall of the metal ring base 5. The outer wall of the metal ring base 5 is uniformly provided with a plurality of heat-dissipating fins 6. The lampwick mounting seat 3 is inserted into the inner cylinder of the metal sleeve 4 and the metal ring base 5. The lampwick body 2 is provided with two lampwick pins 21 and a lampwick electrically connected between the two lampwick pins 21. The bottom of the lampwick body 2 is provided with two clamping grooves 22 matched with the abutting gasket 72. The bottom of the two lampwick pins 21 is extended into the clamping grooves 22 and exposed. The lampwick body 2 is inserted into the lampwick clamping groove 31 and the two clamping grooves 22 are clamped on the abutting gasket 72, so that the bottom of the two lampwick pins 21 is abutted on the abutting gasket 72.
[0019] First, two pin rod insertion holes are opened on the lampwick mounting seat 3 (the insertion holes are opened by a die-casting opening device). The two pin rods 7 are inserted into the pin rod insertion holes from the bottom of the lampwick mounting seat 3. The abutting gasket 72 is welded on the top of the pin rods. At this time, the lampwick body 2 is inserted into the lampwick clamping groove 31 (the sidewall of the lampwick body 2 is provided with a direction sliding rail and the inner sidewall of the lampwick clamping groove is provided with a matched sliding groove, so that when inserted, the square is positive). The clamping grooves 22 are clamped on the abutting gasket 72. The bottom of the two lampwick pins 21 is abutted on the abutting gasket 72 (the sidewall of the lampwick body 2 is coated with glue before being inserted).
[0020] Then, the lampwick mounting seat 3 provided with the lampwick body is inserted from the bottom of the metal ring base 5 and the bottom of the lampwick mounting seat 3 is flush with the metal ring base 5. Then, the metal sleeve 4 is injection molded with the transparent plastic cover 1 and the transparent plastic cover 1 covers the lampwick body 2 (as shown in Figure 1 The outer diameter of the transparent plastic cover 1 is the same as the outer diameter of the metal ring base 5.
[0021] The metal sleeve 4, the metal ring base 5 and the heat dissipation fin 6 are integrally pressure cast, and the whole is made of copper. The copper has fast heat dissipation, and the integrally pressure cast is firm and easy to conduct heat.
[0022] The top of the lamp wick mounting seat 3 exposes the top of the metal sleeve 4 by 8-10 mm, so as to expose the lamp wick body and make the lamp wick body 2 higher than the lamp wick mounting seat 3. The metal sleeve 4 does not affect light emission.
[0023] The upper half of the lamp wick body 2 exposes the lamp wick mounting seat 3, and the lamp wick is in the upper half of the lamp wick body 2. Since the upper half exposes the lamp wick mounting seat 3, the light emitted by the lamp wick will be diffused in all directions.
[0024] The pin rod 7 is sleeved with a square block 71 at a position below the lamp wick mounting seat 3, and the square block 71 is marked with positive and negative electrode labels. This is convenient for distinguishing the positive and negative electrode pin rods.
[0025] The lamp wick mounting seat 3 is easy-to-heat insulating plastic. The polyimide has heat conductivity only next to metal, and has higher heat conduction speed than general living plastic.
