The specific embodiment

Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Referring to figs. 1 through Fig. 3, one embodiment of LED lamp affixed to the ceiling of the present utility model is proposed, this LED lamp affixed to the ceiling comprises chassis 10, LED light source 20, the LED driver 30 being connected with LED light source 20 and lampshade 40, and LED light source 20 and LED driver 30 are installed in chassis 10; Lampshade 40Yu chassis 10 connects, and LED light source 20 and LED driver 30 are covered within it.This LED lamp affixed to the ceiling adopts LED light source 20 to replace traditional annular lamp tube, has that light efficiency is high, the longer service life of the feature such as power and energy saving, environmental protection, and LED light source more 20.

LED light source 20 is comprised of at least three LED substrates 201 and the some LED chips that are welded on LED substrate 201, and LED substrate 201 is to form from base material cutting, and the shape of every LED substrate 201 is identical.The curved setting of LED substrate 201, the radian of every LED substrate 201 is identical, the outer arc of the LED substrate 201 of arc can be fitted with the inner arc of another LED substrate 201, like this, base material is when cutting sawing sheet, between the LED substrate 201 of the center of circle of outputing from base material on same straight line, do not have the waste of base material, thereby can reduce the waste of base material, cost-saving.

Chassis 10, for heat radiation chassis 10, has thermolysis.On chassis 10, be provided with the mounting groove 101 identical and adaptive with LED substrate 201 shapes, the LED substrate 201 in the present embodiment is provided with three, so mounting groove 101 is also provided with three.LED substrate 201 is arranged in corresponding mounting groove 101, LED substrate 201 bottom surface contacts with mounting groove 101 bottom surface, the sidewall contact of the sidewall of LED substrate 201 and mounting groove 101, thereby LED substrate 201Yu chassis 10 fully contacts, can improve heat-transfer rate, thereby radiating efficiency is improved, dispel the heat faster.
