Title:
LED LIGHT SOURCE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2016/154878
Kind Code:
A1
Abstract:
An LED light source structure comprises a lamp cap (1), a power supply module (2), a telescopic positioning-enabled lamp housing (3), a heat dissipation device (4), an LED light-emitting element (5), and a light-transmissive cover (6). The telescopic positioning-enabled lamp housing (3) comprises a first housing body (31) and a second housing body (32) which can be relatively positioned and sliding in an axial direction of the lamp cap (1) and cannot relatively rotate in a vertical plane to an axis of the lamp cap (1). The lamp cap (1) is connected to a top of the first housing body (31). The heat dissipation device (4) is a hat-shaped structure having a hat brim (41), wherein an outer surface of a hat top (42) is fixedly connected to a bottom of the second housing body (32), an inner surface of the hat top (42) is connected to the LED light-emitting element (5), and the hat brim (41) is immediately adjacent to the opening of a corresponding down lamp. The periphery of the light-transmissive cover (6) is connected to the inner surface of the heat dissipation device (4) to cover the LED light-emitting element (5). The LED light source structure overcomes the defect existing when replacing a conventional down lamp lighting system with a current LED lighting product, has a long service life, convenient installation, good decorative effect, and facilitates energy saving and environment protecting.
