Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Referring to fig. 1 to 3, a ceiling lamp includes a lamp body 1 and a base 2, the base 2 is disposed above the lamp body 1, and is used for fixing the lamp body 1 to an external installation base, such as a ceiling.

The lamp body 1 comprises a front lampshade 11 and a rear lampshade 12, a diffusion ring 13, a light guide plate 14, a reflecting film 15 and an LED lamp strip 16 are arranged between the front lampshade 11 and the rear lampshade 12, the front lampshade 11 faces a user (downwards) when in use, and the rear lampshade 12 is fixedly installed on the base 2. The front cover 11 and the rear cover 12 are made of a light-permeable material.

The front light cover 11 includes a cover plate 111 and a ring wall 112 disposed on a side of the cover plate 111 facing the rear light cover 12, in the present embodiment, the cover plate 111 is circular, the ring wall 112 is circular, and the ring wall 112 is located at a position near an edge of the cover plate 111. The diffusion ring 13 is provided on the inner peripheral wall of the annular wall 112, and the light guide plate 14 is supported on an end of the diffusion ring 13 away from the cover plate 111. The reflective film 15 is disposed on a side of the light guide plate 14 away from the cover plate 111, and the reflective film 15 is smaller in size than the light guide plate 14, and a projection of the reflective film 15 on a horizontal plane is located within a projection of the light guide plate 14 on the horizontal plane in a mounted state. The light guide plate 14 and the cover plate 111 of the front lamp housing 11 are spaced up and down, and the reflective film 15 and the rear lamp housing 12 are spaced up and down. In the present embodiment, since the middle of the rear lamp cover 12 is mounted with the chassis 2, light can be emitted only at a position located at the periphery of the chassis 2 (the rear lamp cover 12 may be made of a light-transmitting material only at the portion), and therefore, an area where the reflective film 15 does not cover the light guide plate 14 is the periphery of the reflective film 15, and an area where the reflective film 15 does not cover the light guide plate 14 may be smaller than a portion where the rear lamp cover 12 is located at the periphery of the chassis 2, corresponding to a position where the rear lamp cover 12 is located at the periphery of the chassis 2.

The LED light bar 16 is also annular, and is disposed on the outer periphery of the light guide plate 14 and the reflective film 15, and in the mounted state, its projection on the horizontal plane is located within the projection of the diffuser ring 13 on the horizontal plane. The periphery of the LED light bar 16 is provided with an annular aluminum substrate 17, and the LED light bar 16 can be adhered to the aluminum substrate 17 by using heat-conducting glue. The aluminum substrate 17 is recessed toward the front cover 11 to form a slot 171 in a direction away from the front cover 11, and the annular wall 112 of the front cover 11 can be inserted into the slot 171 to position the aluminum substrate 17.

The light source on the LED lamp strip 16 is towards the light guide plate 14, and when ceiling lamp was opened, the light that LED lamp strip 16 sent was leaded light through the light guide plate 14, upwards respectively with the outgoing downwards, the light that sends the illumination after the light that the lamp housing 11 was gone out to the outgoing downwards, owing to be provided with diffusion ring 13, consequently, can carry out the diffusion once with the parasitic light at light guide plate 14 edge, carry out the secondary diffusion through the lamp housing 11 before again to solve the problem of marginal parasitic light homogeneity. The light emitted upward from the light guide plate 14 is mostly reflected by the reflective film 15, and a part of the light passes through the backlight 12 upward from the area where the reflective film 15 does not cover the light guide plate 14, and then is emitted to form a backlight. Therefore, the light is emitted upwards and downwards in all directions.
