Definitions

  • the present invention relates, in general, to bar type LED lighting apparatuses and, more particularly, to a bar type LED lighting apparatus, in which an upper surface of a main body equipped with an LED module is inclined to both sides to expand a beam angle, the number of respective parts constituting the lighting apparatus is reduced, the parts are air-tightly fastened to each other, a fastening means for mounting the parts is also simple and affords convenience, and a heat dissipating problem occurring in the LED can be overcome by changing a structure of a main body, to increase heat dissipating efficiency, thus allowing the beam angle to be expanded, and ensuring air-tightness as well as a compact structure.
  • a light emitting diode (hereinafter referred to as an 'LED') is a photoelectric conversion semiconductor device consisting of an N-type semiconductor crystal and a P-type semiconductor crystal.
  • a plurality of carriers is electrons in the N-type semiconductor crystal, while a plurality of carriers is holes in the P-type semiconductor crystal.
  • the LED is a semiconductor light emitting device using natural emitting light that is generated when the electrons and holes injected into a PN junction are recombined with each other.
  • an LED light source is arranged only on a front, so that it is limited to expand a beam angle.
  • the bezel part 30 itself closes the side surface of the lighting apparatus and protects the LED module disposed therein, thus enhancing air-tightness due to the double pressurizing structure.
  • an uneven portion 145 is formed laterally on a side surface of the heat dissipation fin 140, thus maximizing a contact area and enhancing the heat dissipating effect.
  • the fastening means T is mounted to the lower surface of the main body 10 to fasten the lighting apparatus to the vehicle.
  • the fastening surfaces 62 are bent rearwards from both ends of the connecting surface 61 and then bent outwards.
