PROBLEM TO BE SOLVED: To improve problems affecting health and work efficiency caused by too strong rays from a direct high ceiling light.SOLUTION: A ceiling light hung down under a ceiling includes a lamp holder, a plurality of joining plates, a plurality of heat radiator plates, a plurality of lighting modules, and a lamp shade. The joining plates are mutually fitted into and connected with each other by corresponding engagement projected ribs in engaging grooves. Each lighting module is assembled to one surface of a plurality of the heat radiator plates. Each lighting module includes an electric circuit board and a plurality of light-emitting diodes. The lamp shade covers the joining plates and includes an accommodation part and an arc shape extension part. Since a reflection surface is installed on an inner surface of the arc shape extension part and the emitting light (source) from each light-emitting diode radiates at first on the reflecting surface to be then reflected outside the lamp shade from the reflecting surface, irradiation rays will never be too strong and dazzling. |
