Embodiment 1, referring to fig. 1 and 2, an LED ceiling lamp of a novel light distribution, the LED ceiling lamp comprising: a lamp body 100 and a heat sink 200, the lamp body 100 including: the outer ring 110, the middle ring 120, the lens 140, the reflecting cup 130 and the light source holder 150, the middle ring 120 is sleeved with the outer ring 110, the light source holder 150, the lens 140 and the reflective cup 130 all fall into the middle ring 120, a COB light source 151 is installed in the middle of the light source bracket 150, the periphery of the light source bracket 150 is clamped with the middle of the heat sink 200, the periphery of the heat sink 200 is provided with a threaded wall 220, the threaded wall 220 is in threaded connection with the inner wall of the middle ring 120, the lens 140 covers the COB light source 151, the reflector cup 130 has an upper opening 132 and a lower opening 133, the caliber of the upper opening 132 is larger than that of the lower opening 133, the upper opening 132 and the lower opening 133 are transitionally connected through a cambered surface, the reflecting cup 130 covers the lens 140 through the lower opening 133, the focal length of the lens 140 is set to f, and the height of the reflecting cup 130 is set to h, wherein f is less than or equal to 0.5 h.

Referring to fig. 3, when the COB light source 151 emits light, the light enters the lens 140, is focused by the lens 140, and is focused at a position below 0.5h of the reflector cup 130, so that the light continues to propagate and is transmitted to the inner wall of the reflector cup 130, and is reflected by the inner wall of the reflector cup 130. Because the light that COB light source 151 sent passes through once focusing, so, the light that COB light source 151 sent is more concentrated, because the focus of lens 140 is less than or equal to 0.5h, consequently, the light that COB light source 151 sent through once focus after alright carry out even diffusion through reflection of light cup 130. The LED ceiling lamp with the structure can emit light with better light distribution parameters. Through the test, the annulus luminous flux of the LED ceiling lamp with the structure is shown in the table 1.
