LED lamp having a large illumination angle
An LED bulb includes a connecting member having an Edison male screw base and an LED module engaging with the connecting member. The LED module includes a circuit board, a first LED and a plurality of second LEDs mounted on the circuit board. The first LED is arranged on a center of the circuit board. The second LEDs are located surround the first LED. The LED bulb furthermore includes a plurality of lens. Each lens covers a corresponding second LED. Each lens includes a light-guiding portion which includes a light input surface and a light output surface. Light emitted from each of the second LEDs travels into the lens via the light input surface, and is refracted out to lateral directions of the LED bulb by the light output surface of the light-guiding portion to obtain a wider illumination range.
