The utility model proposes a kind of LED lamp affixed to the ceiling, the LED driver that comprises chassis, is arranged on the LED light source in described chassis and is electrically connected with described LED light source, described in the bottom on chassis is integrated is provided with some upwards bar shaped boss of protuberancedescribed bar shaped boss is radial arrangement around the central shaft on described chassis, described bar shaped boss is from inside to outside downward-sloping setting, described LED light source is and the LED light source bar of the bar shaped of the upper surface adaptation of described bar shaped boss that described LED light source bar is fastened on the upper surface of described bar shaped boss.

Preferably, the sidewall of described bar shaped boss is from the top down outward-dipping reflection cambered surface.

Preferably, at described bar shaped boss and the corresponding connecting hole that is provided with on corresponding described LED light source bar, described LED light source bar is connected by screw and is fixed on described bar shaped boss.

Preferably, described chassis is that the metal material with conductive force is made.

The beneficial effect of LED lamp affixed to the ceiling of the present utility model is:

1, the fitting operation of LED light source plate is simple and easy, quick: on the chassis of LED lamp affixed to the ceiling, be provided with bar shaped boss, LED light source plate correspondence is placed on bar shaped boss, and lock by screw, can complete the installation of LED light source plate, be beneficial to location, make the fitting operation of LED light source plate simpler and easy, can improve the installation effectiveness of LED light source.

2, distribution of light is even, chassis central authorities and no dark space, edge: the bottom on chassis is integrated is provided with some upwards bar shaped boss of protuberancebar shaped boss is radial arrangement around the central shaft on chassis, and bar shaped boss is from inside to outside downward-sloping setting, and LED light source bar is fastened on the upper surface of bar shaped boss, LED light source bar is radial arrangement around the central shaft on chassis, be coiled into ring-type, the central authorities of illuminating chassis are gathered in the inner of LED light source bar around central shaft, and the outer end of LED light source bar is downward-sloping, illuminate the edge on chassis, LED light source is so arranged, and makes distribution of light more even, can eliminate central authorities and the dark space, edge on chassis.

3, base material wastage is few: LED light source is and the LED light source bar of the upper surface adaptation of bar shaped boss, be bar shaped setting, thereby substrate is bar shaped, when bar shaped substrate sawing sheet, between the bar shaped substrate of outputing, fit, gapless, the leftover bits and pieces producing is few, can reduce the waste of base material, greatly cost-saving.
