When the light-emitting component 1 is applied to a terminal device, the light-emitting component is fixed in the casing, and the light-emitting element 12 is connected to the circuit board of the terminal device at 2 points through pins. When the circuit board 2 controls the first pin to be energized, the first light-emitting element 121 emits light; when the circuit board 2 controls the second pin to be energized, the second light-emitting element 122 emits light, and the circuit board 2 selectively controls each light-emitting element 12 to emit light .

In the prior art, as shown in FIG. 1, only one side of the substrate 11' is provided with a light-emitting element 12'. When installed in the housing, the two substrates 11' are stacked on both sides of the circuit board 2', and the two substrates 11' The light-emitting element 12' on the top faces in the opposite direction. Such an arrangement makes the overall size of the light-emitting component 1' in the thickness direction of the casing larger, and correspondingly, the overall thickness of the terminal device needs to be increased. However, in the present invention, light-emitting elements 12 are provided on both sides of the substrate 11.

In order to achieve the above purpose, the light-emitting component can be arranged in various ways. The structure of the light-emitting component and the terminal device will be introduced in detail below by taking the application of the light-emitting component to a terminal device as an example.

The substrate 11 may be a ceramic substrate 11, which has outstanding characteristics of high temperature resistance and high electrical insulation performance, and ceramics have low dielectric constant and dielectric loss, high thermal conductivity, and good chemical stability.
