Detailed description of the invention

With reference to Fig. 1, Fig. 2, Fig. 3, a kind of energy-saving LED lamp that the utility model proposes, comprising: the cross section perpendicular to axis direction is the substrate 1 of arc, circuit board 2 and driver module.

Circuit board 2 is provided with multiple LED chip and peripheral circuit, and multiple LED chip is along the arrangement of circuit board 2 length direction, and on circuit board 2, multiple LED chip is uniformly distributed, and multiple LED chip line is positioned in the middle part of circuit board.So, under can ensureing circuit board 2 duty, the uniformity that LED chip light covers, improves human eye level of comfort.

Substrate 1 periphery is provided with multiple mounting groove 3, mounting groove 3 is evenly distributed along substrate 1 arc section, circuit board 2 is arranged in mounting groove 3 correspondingly, is specifically bonded and fixed in mounting groove 3 by colloid, and the LED chip place straight line on each block circuit board 2 is all parallel to substrate 1 axis.By being evenly distributed of mounting groove 3, LED chip being evenly distributed in substrate 1 periphery can be ensured, thus ensure the uniformity of dispersing of light.

Driver module is arranged on substrate 1 concave surface side, and is connected with circuit board 2 respectively.Particularly, be provided with through hole 5 bottom mounting groove 3, driver module is by being connected and installed the circuit board 2 in groove 3 through the cable of each through hole 5.The setting of through hole 5, is conducive to the heat radiation of circuit board 2 in mounting groove 3.In present embodiment, in order to improve radiating efficiency further, be also vertically provided with multiple fin 6 at substrate 1 concave surface, and distance between arbitrary neighborhood two fin 6 is equal.
