INFRARED LIGHT-EMITTING DEVICE, AND MOBILE TERMINAL

Document Type and Number:

WIPO Patent Application WO/2017/219316

Kind Code:

A1

Abstract:

Disclosed are an infrared light-emitting device (10), and a mobile terminal (100) using the infrared light-emitting device. The infrared light-emitting device (10) comprises an infrared light emitter (1) and a light cover (2). The light cover (2) comprises a fixed column (21) and a positioning platform (22) connected to each other. The fixed column (21) comprises a light-entering surface and a light-exiting surface (211) opposite to each other, and a side surface (212) connecting the light-entering surface and the light-exiting surface (211). The light-entering surface is connected to the positioning platform (22). The light-exiting surface (211) is at a distance from the positioning platform (22). The side surface (212) is used in coordination with a casing (20) of the mobile terminal (100), so that the light cover (2) is fixed to the casing (20). A light condensing surface (221) is formed on one side of the positioning platform (22) at a distance from the fixed column (21). The light condensing surface (221) comprises a concave surface, and directly faces the infrared light emitter (1), so as to receive infrared light emitted by the infrared light emitter (1). The infrared light-emitting device of the present invention has powerful remote control functionality.
