Title:
FLEXIBLE LED SURFACE LIGHT SOURCE AND MANUFACTURING METHOD THEREFOR, AND LIGHT EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/191546
Kind Code:
A1
Abstract:
Disclosed are a press-formed flexible LED surface light source and manufacturing method therefor. The LED surface light source is formed by attaching LED chips to a flexible circuit board and directly carrying out pressing and packaging. The LED surface light source emits uniform light, can be folded in any manner, features a small thickness, and can be widely applied to fields such as physiotherapy healthcare and display. The flexible LED surface light source comprises: a flexible circuit board having an upper surface provided with a conductive circuit, a plurality of LED solder points being provided on the conductive circuit; a flip LED chip array which is mounted on the flexible circuit board by means of the plurality of LED solder points and implements electrical connection by means of the conductive circuit; and a packaging layer which is press-formed by a liquid adhesive by means of a mold and covers the front surface of the conductive circuit and the LED chips.
