Title:
LED LIGHT SOURCE, LED MODULE, BACKLIGHT MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/149081
Kind Code:
A1
Abstract:
An LED light source (51), an LED module (50), a backlight module (20), and an electronic device. The LED light source (51) comprises a light emitting body (53), a bracket (54) and pole pieces (55). The bracket (54) is provided with a light emitting surface (501), the light emitting body (53) is encapsulated within the bracket (54), and light emitted from the light emitting body (53) is emitted from the light emitting surface (501). The pole pieces (55) comprise a first pole piece (56) and a second pole piece (57), the first pole piece (56) comprising a first body part (561) and a first welding part (562), and the second pole piece (57) comprising a second body part (571) and a second welding part (572). The first body part (561) and the second body part (571) are encapsulated within the bracket (54) and are electrically connected to the light emitting body (53). The first welding part (562) extends from the first body part (561) in the direction away from the light emitting surface (501), and a first protrusion (563) is formed by bending and protruding from the end of the first welding part (562) away from the light emitting surface (501), and the second welding part (572) extends from the second body part (571) in the direction away from the light emitting surface (501), and a second protrusion (573) is formed by bending and protruding from the end of the second welding part (572) away from the light emitting surface (501), and the first protrusion (563) and the second protrusion (573) are opposite to each other. As a result, the LED light source (51) has its lamp beads reduced in size without lowering its welding stability.
