Detailed Description

For further understanding of the features and technical means, as well as the specific objects and functions of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. The description of the relative positional relationship of the components of the present invention is only made with reference to the orientation of the components shown in the drawings, and does not represent an absolute limitation to the scope of the present invention.

Refer to fig. 1 to 4. The utility model provides an ultra-thin side-emitting LED ceiling lamp, includes drain pan 1, installs LED lamp strip 2 in drain pan 1, covers the frame 4 of diffusion sheet 3 and fixed diffusion sheet 3 on the light-emitting port of drain pan 1.

The bottom case 1 includes a bottom wall 11, a side wall 12 surrounding an edge of the bottom wall 11, and a support rib 13 provided on the bottom wall 11. The LED lamp strip 2 comprises a circuit board 21, a plurality of LED lamp beads 22 and electronic elements 23 which are dispersedly arranged and form a driving power supply are uniformly arranged on the front surface of the circuit board 21 at intervals, and each electronic element comprises a capacitor 231, a chip 232, a resistor 233 and the like. Drive power supply truns into 220V high voltage alternating current into the low voltage direct current that is fit for LED lamp pearl to use, like this the utility model discloses can the lug connection commercial power. A plurality of independent series modules 20 are formed by the LED lamp beads 22, a parallel relation is formed among the series modules 20, and each series module 20 is internally provided with an electronic element 23 forming a driving power supply, so that the power of the electronic element can be reduced, the electronic element is miniaturized, the thickness of a bottom shell is further reduced, and on the other hand, the failure of the whole lamp caused by the fact that any one LED lamp bead is broken is also prevented.
