Title:
LED LAMP PROVIDED WITH LIGHT TRANSMISSIVE MASKS
Document Type and Number:
WIPO Patent Application WO/2017/206324
Kind Code:
A1
Abstract:
An LED lamp provided with light transmissive masks, comprising a light emitting diode and light transmissive masks (20), the light emitting diode comprising a printed circuit board (11), a heat dissipation substrate (12), and M light emitting wafers (16), M being a natural number greater than or equal to 1, and the number of light transmissive masks (20) being M. The printed circuit board (11) and the heat dissipation substrate (12) are bonded together and M through openings are disposed in the printed circuit board (11), each light emitting wafer (16) being arranged at an opening and the bottom of the light emitting wafer (16) being attached to the surface of the heat dissipation substrate (12). A circuit is etched onto a surface conductive copper layer of the printed circuit board (11), the pins (161) of each light emitting wafer (16) all being electrically connected to the circuit on the printed circuit board (11). Each light transmissive mask (20) masks a light emitting wafer (16), each light transmissive mask (20) comprising a mask body, the cross-section of the mask body being in a "Π" shape, and the inner walls of the mask body being provided with a plurality of light transmissive strip grooves (22) distributed in a wave shape.
