The invention discloses an LED ceiling lamp with an optical lens cover. The LED ceiling lamp comprises a lamp plate and a reflection cup with the inner surface and the outer surface capable of reflecting light. The lower end of the reflection cup is arranged on the lamp plate, and LED light sources are arranged at the positions, inside and outside the lower end of the reflection cup, of the lamp plate. The lower end of the reflection cup is buckled on the lamp plate, the LED light sources are arranged at the positions, inside and outside the lower end of the reflection cup, of the lamp plate,only one lamp plate exists, it is ensured that the cost cannot be increased, machining assembling difficulty is reduced, on the other hand, the heat dissipating path is enough, and the heat dissipating effect is not affected; light emitted by the LED light source in the reflection cup passes through the inner surface of the reflection cup to be reflected and refracted, the light emit angle is increased, light emitted by the LED light source outside the lower end of the reflection cup passes through the outer surface of the reflection cup to be refracted and reflected, the light emit angle is further increased, and the large-angle emit-lighting LED lamp can be wholly formed.
