In other embodiments, the collecting lens group 20 may include a plurality of collecting lenses 21 with the same main optical axis, and the number of collecting lenses 21 in the collecting lens group 20 is related to the beam quality of the light beam generated by the light emitting chip 11 in the lighting device 1. When the light emitting chip 11 having higher output beam quality is used in the illumination device 1, the number of collecting lenses 21 in the collecting lens group 20 can be set smaller; when the light-emitting chip 11 used in the lighting device 1 has low beam quality, the collection capability of the collection lens group 20 for the light beam emitted by the light-emitting chip 11 is improved by increasing the number of the collection lenses 21 in the collection lens group 20 or replacing the collection lens 21 with higher collection capability for the light beam.

Optionally, the lighting device 1 further includes a pattern disc 60, and the pattern disc 60 is disposed on the optical path of the light beam converged by the first condenser lens 30, and is used for changing the shape of a light spot formed by the converged light beam. As shown in fig. 6, the pattern disc 60 of the present embodiment is circular, and the artistic modeling and the lighting effect of the lighting apparatus 1 applied to the stage lighting can be expressed by the patterns and the number of the pattern disc 60, and the more the pattern effect on the pattern disc 60 is, the richer the light beam effect obtained by the lighting apparatus 1 is by adjusting the pattern effect of the pattern disc 60.

Optionally, the lighting device 1 further comprises a filter 70, the filter 70 being arranged adjacent to the pattern disc 60 for changing the color of the light beam. The filter 70 is disposed between the first collecting mirror 30 and the pattern disk 60 or between the pattern disk 60 and the second collecting mirror 50, and can be dynamically adjusted, and the filter 70 can be a filter wheel 71 or a linear filter 72.

Alternatively, in the case where the illumination device 1 requires high beam uniformity, the fly-eye lens 80 may be provided in the illumination device 1. The fly-eye lens 80 is disposed on the light path of the light beams collected by the collection lens group 20, and homogenizes the light beams collected by the collection lens groups 20, thereby improving the uniformity of the light beams by using the fly-eye lens 80.

The fly-eye lens 80 in the lighting device 1 is conventionally used by using an anterior fly-eye lens and a posterior fly-eye lens in combination. When the light source irradiates the back fly-eye lens after passing through the front fly-eye lens, the light beam in the middle is large, the light beam at the outer edge is small, and the long axis direction of the light beam has an inclination angle. If each lenslet on the back fly-eye lens is made to be the same size, it will cause "spill-over" of the light beam at the center, and the light beam at the outer edge will not fully impinge on the corresponding lenslet. And because the small lenses on the front fly-eye lens and the rear fly-eye lens are in corresponding relation, the light energy can only play a role when the light rays emitted from one small lens of the front fly-eye lens irradiate the corresponding small lens in the rear fly-eye lens, and if the light rays irradiate other lenses in the rear fly-eye lens, the light rays also become stray light and are lost. Therefore, a large part of the light energy at the center and the outer edge is lost, and the energy utilization rate is low. In the embodiment, the front fly-eye lens and the rear fly-eye lens are manufactured into a whole by using the double-sided fly-eye lens, so that the front fly-eye lens and the rear fly-eye lens are positioned on two opposite surfaces of the same glass plate or other light-transmitting bodies, the space is greatly saved, the installation is convenient, and the transmittance and the uniformity of light beams are greatly improved.

Further, the first condenser lens 30 disposed at one side of the rear fly eye lens among the double-sided fly eye lenses converges the light beam after transmittance and uniformity of the light beam are improved based on the double-sided fly eye lens, so as to obtain a uniform light beam.
