  • the present invention relates to a lighting set, especially to a light emitting diode (LED) lighting set.
  • LED light emitting diode
  • the present invention is to solve the heat dissipating issue of the lighting sets.
  • Conventional LED lighting set comprises a pipe, an LED module, and two electrical connectors; the pipe is transparent, with a number of heat dissipating holes formed thereon; the LED module is received in the pipe, which comprising a substrate and a plurality of LED lamps electrically connected to the substrate.
  • the LED lamp When the LED module is electrified, the LED lamp then sends out light and at the same time emits heat, the heat produced thereby is transformed to the substrate and dissipated via the heat dissipating holes.
  • the conventional LED lighting set has the following drawback in actual use: since heat produced by the LED lamps is transformed to the substrate and sends out via the heat dissipating holes, the LED lamps is cooled via convection of outer atmosphere, therefore the cooling effect is not noticeable, thus the heat dissipating effect is affected, and thus the usage life-span of the LED lamps is reduced.
  • the present invention relates to an LED lighting set, with the design of aluminum extrusion radiating base and that of pasting an LED module onto the radiating base, the LED lighting set gains the advantages of good heat dissipating effect and furthermore improved usage life-span.
  • the present invention provides an LED lighting set, which comprising an aluminum extrusion radiating base, an LED module, a light focus plate, a diaphanous cover, and two electrical connectors;
  • the LED module comprising a substrate settled onto the radiating base and a plurality of LED lamps electrically connected to the substrate, the light focus plate fixed onto the radiating base and correspondingly formed under the LED lamps; the diaphanous cover connecting the radiating base and correspondingly formed under the light focus plate; the two electrical connectors separately connecting two ends of the radiating base and also electrically connecting the substrate; wherein the aluminum extension radiating base, the diaphanous cover and the two electrical connectors defining a closed space together, and the LED module and the light focus plate being received therein.

  • the base-plate 11 comprises a plurality of screw holes 111.
  • Each of the two side-plates 12 comprises a block groove 121 and a corresponding catching groove 122.
  • Securing holes 112 are separately mounted at two ends of the base-plate 11.
  • the LED module 20 comprises a substrate 21 and several LED lamps 22, the LED lamps 22 are electrically connected to the substrate 21.
  • the substrate 21 is settled onto the base-plate 11 of the radiating base 10, therefore making the LED module 20 received among the base-plate 11 and the two side-plates 12.
  • the substrate 21 comprises several through holes 23 corresponding to the screw holes 111, enabling a bolt 24 drill through the through holes 23 and the screw holes 111, which makes the LED module 20 locked onto the base-plate 11.
  • a material of the substrate 21 could be copper or silver, therefore leading to improvement of heat conducting rate.
