[0016] see figure 1 , figure 2 and image 3 , the lighting device 10 provided in this embodiment includes a first light source 13 , a primary lens 17 , a reflective element 19 and a secondary lens 18 . The first light source 13 is used for emitting first light. The primary lens 17 is located on the outgoing light path of the first light source 13 , and the distance from the center of the primary lens 17 to the center of the first light source 13 is L0. The reflective element 19 reflects the light emitted by the primary lens 17 to the secondary lens 18, wherein the distance of the optical path from the center of the primary lens 17 to the center of the secondary lens 18 is L1. The secondary lens 18 converges the light reflected by the reflective element 19, wherein the radius of the secondary lens 18 is R2. L0+L1≤2R2.
[0017] Specifically, in this embodiment, the first light source 13 is a light-emitting diode. It can be understood that the first light source 13 can be a...

[0081] see Figure 4 and Figure 5 , different from the first embodiment, the wavelength conversion element 25 of the illumination device 20 provided in this embodiment includes a first conversion region 251 and a second conversion region 253 .
[0082] The first conversion area 251 can be arranged in the center of the wavelength conversion element 25, and the center of the first conversion area 251 can be located on the main optical axis L. The first conversion area 251 is the incident surface of the second light source 11, and is used for converting the third light M3 is converted into fourth light M4. Of course, a small part of the first light M1 will also be converted into the second light M2 through the first conversion region 251 . The shape of the first conversion region 251 is not limited, the size can be similar to the spot of the third light M3, the material can be all solid-state fluorescent material, and the color of the material can be red, green, blue and so on...
