[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] A light-emitting diode includes a transparent glass substrate 1, a transparent resin platform 3, a light-emitting chip 4, and a transparent glass cover 2;
[0019] The transparent resin platform 3 is fixedly disposed at the upper center of the transparent glass base plate 1. The transparent resin platform 3 is insulated. The light-emitting chip 4 is disposed at the upper end of the transparent resin platform 3 with its bottom facing down. The substrate of the light-emitting chip 4 is located at the lower end. Four downward-facing metal springs 5 are welded to the lower end of the light-emitting chip 4. Slots 6 extending downward from the upper end are provided on the four sides of the transparent resin platform 3. The four metal springs 5 are respectively matched and inserted into the slots 6 around the transparent resin platform 3 to clamp the transparent resin platform 3. The bottom of the slot 6 is provided with an inwardly extending limiting hole 8. The lower end of the metal spring 5 protrudes and is provided with a limiting hook 7 that is embedded in the corresponding limiting hole 8.
[0020] Two downward-extending pins 11 are fixed on the transparent glass base plate 1. The two pins 11 are respectively connected to the positive and negative terminals of the light-emitting chip 4 through a metal wire 12.
[0021] The transparent glass cover 2 is placed over the upper end of the transparent glass base plate 1 and fixedly connected. The fixing method adopts existing technology, such as sealing with sealant or flame sintering the connection between the transparent glass cover and the transparent glass base plate. The transparent resin platform 3, the light-emitting chip 4, the metal spring 5 and the metal wire are all located inside the transparent glass cover 2.
[0022] The light-emitting chip 4 is clamped by four metal springs 5 at the lower end of the transparent resin platform 3 located in the center of the transparent glass base plate 1, so that the light-emitting chip 4 is located in the center and is not easy to shift. Furthermore, the light-emitting chip 4 is restricted to the upper end of the transparent resin platform 3 by the cooperation of the limiting hole 8 and the limiting hook 7.
[0023] In a preferred embodiment, the bottom of the light-emitting chip 4 is connected to the upper end of the transparent resin stage 3 via a solder layer 13. The solder layer 13 is used to solder the light-emitting chip 4 to the transparent resin stage 3 via reflow soldering, further fixing the light-emitting chip 4 to the upper end of the transparent resin stage 3.
[0024] In a preferred embodiment, the upper end of the bottom of the transparent glass is provided with an annular limiting groove surrounding the transparent resin platform 3, and the lower end of the transparent glass cover 2 is provided with an annular limiting edge 9, which is fitted into the annular limiting groove. Through the cooperation of the annular limiting groove and the annular limiting edge 9, the center of the transparent glass cover 2 is aligned with the center of the transparent glass base plate 1 without any offset.
[0025] In a preferred embodiment, the upper end of the transparent glass base plate 1 has two grooves, both located inside the transparent glass outer cover 2. Metal connectors 10 are fixedly installed within the grooves. The upper ends of two leads 11 are connected to the two metal connectors 10 respectively, and two metal wires are connected to the two metal connectors 10 respectively. Because the leads 11 are thinner and have a smaller cross-sectional area, connecting the metal wires 12 through the metal connectors 10 with larger cross-sectional areas facilitates wiring.
[0026] In the preferred embodiment, the two pins 11 are located on opposite sides of the transparent resin stage 3. This ensures that the two metal wires 12 are located on opposite sides of the transparent resin stage 3, preventing them from colliding and short-circuiting.
