technical field

The utility model relates to a light-emitting device, in particular to a thin and portable flexible light-emitting device, which is especially suitable for phototherapy on acupuncture points of human skin.

Background technique

Based on energy issues, current light emitting devices have gradually used light emitting diodes as light sources. These light-emitting devices can be roughly classified into organic light-emitting devices and inorganic light-emitting devices, depending on whether organic light-emitting diodes or inorganic light-emitting diodes are used as light sources.

Please refer to Figure 1, Figure 2, Figure 3 and Figure 4 at the same time. FIG. 1 is a schematic diagram illustrating the appearance of a flexible light emitting device 100 according to an embodiment of the present invention; FIG. 2 is an exploded schematic diagram illustrating the flexible light emitting device 100 in FIG. 1; FIG. A cross-sectional view of the flexible light emitting device 100 in a first use state; and FIG. 4 is a cross-sectional view of the flexible light emitting device 100 in FIG. 1 in a second use state.

The flexible light emitting device 100 basically includes a flexible upper cover 110 , a power supply unit 120 and a light emitting unit 130 . In this embodiment, a flexible lower cover 140 may be further included.

The flexible upper cover 110 includes an accommodating space 111 and a pulling portion 112 . In one embodiment, the triggering portion 112 is formed by a partial area of the flexible upper cover 110 ; for example, a corresponding and bendable triggering portion 112 is formed on the flexible upper cover 110 .
