Description

Plug-in LED packaging structure for fuses

technical field

The utility model relates to a light-emitting diode, in particular to a plug-in type light-emitting diode packaging structure dedicated to fuses.

Background technique

At present, the fuses used in automobiles are electrically connected to the control circuit of the automobile equipment to ensure that the equipment electrically connected to the circuit will not be reversed due to the instantaneous start of the automobile or the instantaneous pressing of the switch. Surge signal) to burn out.

Since the fuse of the automobile fuse that was manufactured earlier is blown after the fuse connected between the two conductive inserts, it cannot be directly observed from the appearance of the fuse housing. Therefore, when overhauling, the maintainer must pull out each fuse one by one to check, which will result in time-consuming and labor-intensive maintenance. In order to facilitate overhaul or maintenance, a low-resistance light-emitting diode is electrically connected between the two conductive inserts of the car fuse. When the fuse electrically connected between the two conductive inserts is blown, the current will be Flow through the light emitting diode, so that the light emitting diode is lit. After the maintainer opens the fuse box, he can directly see which fuse's light-emitting diode is lit, which means that the fuse of the fuse has been blown, so that the maintainer can repair or replace the fuse.

However, the light-emitting diode connected between the two conductive inserts is a low-resistance component, so when the current flowing through the light-emitting diode is too large, it will burn the light-emitting diode. Therefore, in order to prevent the light-emitting diode from being burned, a high-resistance resistor component is electrically connected to one of the pins of the light-emitting diode. Although connecting a high-resistance resistor component in series with one of the light-emitting diodes can ensure that the light-emitting diodes will not be burned, such a connection method is likely to cause troubles in production.

The chipset is composed of first and second resistor chips and first and second light-emitting chips. The first resistor chip and the second light-emitting chip are crystal-bonded on the first convex electrode. The light-emitting chip is crystal-bonded on the second convex-shaped electrode.
