The light of the LED light source 2 is sequentially emitted through the reflection portion 3 and the fly-eye lens 5, and the reflection portion 3 and the compound eye The lens 5 is a separate component. When the light of the LED light source 2 passes through the reflecting portion 3, the reflecting portion 3 shrinks the light of the LED light source 2 into a light beam of a predetermined beam angle, for example, 10°, 20° or 30°; The light of the light source 2 passes through the fly-eye lens 5 The fly-eye lens 5 then increases the beam angle of the beam to a predetermined angle, such as 40°, 50°, and the like.

For example, when the angle of the reflecting portion 3 is 11°, that is, when the light beam angle of the light beam of the LED light source 2 passes through the reflecting portion 3 is 11°, the beam angle of the lamp beam is The relationship between the chord height and the radius of the fly-eye lens unit 51 is as follows:

For example, when the angle of the reflecting portion 3 is 20°, that is, when the light beam angle of the light beam of the LED light source 2 passes through the reflecting portion 3 is 20°, the beam angle of the lamp beam is The relationship between the chord height and the radius of the compound eye lens unit 51 is as follows:
