Definitions

  • the present invention relates to a lamp structure, and more particularly to a lamp structure with focused bright light, its illumination angle is as large as 180 degrees, and the lamp has a long life, good heat dissipation and is environmental friendly.
  • the present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
  • the primary objective of the present invention is to provide a lamp structure with focused bright light, its illumination angle is as large as 180 degrees, and the lamp has a long life, good heat dissipation and is environmental friendly.
  • the lamp structure provided in accordance with the present invention comprises:
  • the light emitting diode is of any color and is high power.
  • FIG. 1 is an exploded view of a lamp structure in accordance with a preferred embodiment of the present invention.
  • the lamp structure comprises: a slim light emitting source 1, a reflector 2, a flat lens 3, a lamp housing 4 and a driver 5.
  • the light emitting source 1 includes one or more high power LED (light emitting diode) 10 packaged on a MPCB (multilayered printed circuit board) aluminum base 11, and the LED 10 can be of any color.
  • MPCB multilayered printed circuit board
  • the LED 10 can be of any color.
  • Around the periphery of the aluminum base 11 are oppositely arranged two locking grooves 12 for passage and electrical connection of the positive and negative leads 50 of the driver 5 and a plurality of gaps 13 for making it easier to take out the light emitting source 1 from the lamp housing 4 when replacement is required.
  • the reflector 2 is funnel-shaped and concaved toward the center thereof, in the bottom of the reflector 2 are defined one or more holes 20 for accommodation of a part of the surface of the LED 10, and the inner surface of the reflector 2 is coated to form a light reflecting surface for adjusting the illumination angle, eliminating shade, and focusing the light generated from the light source while preventing waste of light.
  • the surface of the flat lens 3 is treated with sand blast to blend the light source and carry out luminous reflectance, so that the illumination angle can be adjusted up to 180 degrees, ghosting is prevented, and the light source is emitted out in a focused way.
  • the lamp housing 4 includes a receiving chamber 40, one end of which is accommodated with the slim light emitting source 1, the reflector 2, and the flat lens 13, respectively, and the other end of which is provided for insertion of the driver 50.
  • the outer surface of the lamp housing 4 is formed with a plurality of heat dissipation fins 41.
  • the driver 5 is inserted in the other end of the lamp 4 and has positive and negative leads 50 connected to the slim light emitting source 1 for making it to produce light.
  • Fig. 2 which is a perspective view of a lamp structure in accordance with the preferred embodiment of the present invention
  • the light emitting source 1 is inserted in the receiving chamber 40 of the lamp housing 4, and then the reflector 2 is inserted with its holes 20 aligned and engaged with the LEDs 10.
  • the flat lens 3 is assembled, and then the driver 5 is inserted into the other end of the receiving chamber 40 with its positive and negative leads extending into electrical contact with the light emitting source 1, as shown in Figs. 3 and 4 , thus forming a lamp.
  • the operating voltage of the lamp is 12 V, and because of the high power LEDs 10, the light emitting source 1 will produce bright enough light and has a long life.
  • the reflector 2 can adjust the illumination angle of the LEDs 10, illuminate shade, and focus the light of the light emitting source.
  • the sand blasted flat lens 3 can blend the light emitting source to have an illumination angle of 180 degrees, and thus ghosting is prevented.
  • the fins 41 around the outer periphery of the lamp housing 4 can effectively improve the heat dissipation efficiency.
