Document Type and Number:
Japanese Patent JP2017139309
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an LED module capable of preventing generation of a color shift in an adjacent LED, and improving light utilization efficiency.SOLUTION: An LED module 1 comprises a substrate 3, an LED 2, and a lens 4. The lens 4 comprises a salient 5 which swells in a direction in which an upper surface 2a of the LED 2 faces, and an inclined part 6 arranged between the salient 5 and the substrate 3. A surface 5a of the salient 5 curves so as to separate from the substrate 3 as it gets close to a central axis 2c of the LED 2. A surface 6a of the inclined part 6 gets close to the substrate 3 as it gets close to the central axis 2c in a cross section including the central axis 2c of the LED 2.SELECTED DRAWING: Figure 2
