Patent ID: 8240879

Claim:
An illumination module, comprising: a substrate, having a main plane, the main plane comprising a central region and a peripheral region; and a plurality of light emitting diode (LED) devices, disposed on the main plane of the substrate in the central region and the peripheral region, each of the LED devices having a light-exiting direction, and each of the LED devices comprising: an LED; and a reflective lampshade surrounding the LED and being attached on the substrate, and each of the reflective lampshades having a central line, wherein an included angle between the central line and a sidewall of each of the reflective lampshades in the central region is larger than an included angle between the central line and a sidewall of each of the reflective lampshades in the peripheral region so that an emitting angle range of each of the LEDs in the central region is larger than an emitting angle range of each of the LEDs in the peripheral region; wherein the light-exiting direction of each of the LED devices disposed in the central region is substantially perpendicular to the main plane, and the light-exiting direction of each of the LED devices disposed in the peripheral region goes outwards with respect to the central region.
