Claim 0:
1. A lens for covering a light source, comprising:
a first irradiation part (2) having a concave surface and a convex surface, the concave surface being defined by a first curve line, the convex surface being defined by a second curve line, the first curve line being substantially similar to the second curve line;
a second irradiation part (3) attached to the first irradiation part (2);
a concave space (1), defined by the first irradiation part (2) and the second irradiation part (3), for accommodating the light source (100),
wherein
the second irradiation part (3) is defined by a convex transmitting surface (311), a plane-transmitting surface (312), a reflecting surface (32), and a second light emission surface (33), the convex transmitting surface (311) and the plane-transmitting surface (312) face the light source, the convex transmitting surface (311) is defined by a third curve line, the convex transmitting surface (311) is connected to the concave surface, the plane-transmitting surface is defined by a straight line and connected to the convex transmitting surface (311), and
a main light beam emitted from the first irradiation part (2) and a main light beam emitted from the second irradiation parts (3) form an acute angle.
