A bottle beam is generated using an axicon- lens system and an incoherent blue LED source. It is demonstrated that the bottle beam can be obtained via an axicon-lens system illuminlated by an incoherent source. According to diffraction theory and the superposition of multi-wavelength, the intensity distribution of light field which is generated by a certain frequency bandwidth of partially coherent light propagating through an axicon-lens system is analyzed. The three-dimensional intensity distribution of the beam evolution and the transverse intensity distributions at different propagating distances are simulated. In the experiment, a blue LED source combined with an axicon-lens system is used to generate the bottle beam. The transverse intensity distribution of the bottle beam is recorded by a stereomicroscope. The experimental results are consistent well with the theoretical analysis, and the result shows a guidance and practical significance for particle trapping and atom cooling.
