Title:
LED MODULE STRUCTURE HAVING A FLUORESCENCE SHEET
Document Type and Number:
WIPO Patent Application WO/2013/139313
Kind Code:
A1
Abstract:
An LED module structure, comprising a heat radiating member (1), and also comprising a fluorescence sheet (5), a light source module (2), and a light source cover (3) attaching said light source module (2) to said heat radiating member (1); a step is provided on said light source cover (3), and said fluorescence sheet (5) is disposed on said step. By means of the addition of a fluorescence sheet (5) to an LED module structure, and the fluorescence sheet (5) being distant from the LED chip (221) and having no direct contact with the heat source, the invention solves the problem of fluorescent powder attenuation caused by the heat of direct contact with the LED chip, and reduces the problem of color coordinate shift in an LED module over time.
