Definitions

  • This invention relates to an easily collapsible LED bulb.
  • LED Light-Emitting Diode
  • LED Light-Emitting Diode
  • it has been popularly developed as light source for so- called LED bulbs used to replace incandescent bulbs and fluorescent bulbs.
  • the conventional LED bulbs are driven by direct current, so they need to be installed with power adapters and driving circuit modules to convert AC into DC so as to light up LED.
  • the power adapter and the driving circuit module are fixed together solidly with other LED devices on a bulb base.
  • the whole LED bulb has to be cast aside if any one of its components is broken down and impossible to be replaced.
  • the power adapter and the driving circuit module are comparatively pricy, they are uneasy to get damaged. In other words, it is LED itself that is comparatively apt to break down. Therefore, if the power adapter and the driving circuit module have to be thrown away together with the LED in case of merely a damage of LED, the LED bulbs have a high cost far beyond that of the incandescent bulbs and fluorescent bulbs, not beneficial for their popularity.
  • the object of this invention is to offer an easily collapsible LED bulb with a lighting module that can be easily disassembled by users.
  • the main characteristics of the invention are a lamp base and a lighting module.
  • the lamp base is provided with plural combining holes and a first connector, with each combining hole having a broad portion and a slender portion extended outward from the broad portion.
  • the slender portion possesses a width narrower than that of the broad portion.
  • the lighting module is installed in the lamp base, further provided with a lamp hood, at least a flexible member, a base board and plural fixing members.
  • the lamp hood is provided with plural first engaging members corresponding to the combining holes of the lamp base.
  • the flexible member is deposited at one side of the first engaging member of the lamp hood.
  • the base board is elastically pressed by the flexible members, provided with plural LEDs electrically connected with a second connector that is connected with the first connector of the lamp base. And bored in the base board to correspond to each of the first engaging member is a through hole.
  • the fixing members are inserted in the through holes respectively, with one end formed as a second engaging member to fixedly engage with the first engaging member, and with another end extended out of the through hole to expansively form as a head.
  • the head is inserted through the broad portion of the combining hole and moved to be restricted in the slender portion so as to make the lighting module fixed on the lamp base.
  • the base board is elastically squeezed by the flexible members to tightly rest on the lamp base.
  • a preferred embodiment of an easily collapsible LED bulb 100 in the present invention is applicable as ceiling lamps, consisting of a lamp base 10, a lighting module 20 and a transparent covering 30.
  • the easily collapsible LED bulb 100 of the present invention can be properly designed for being used as ceiling lamps, recessed lamps, light bulbs and light tubes etc. but not limited.
  • the lamp base 10 is made of metal, provided with an accommodating chamber 11 formed in the center with a bottom 111, a first connector 12 located in the center of the bottom 111 to output power, plural combining holes 13 bored outward around the first connector 12 in the bottom 111, and plural fixing holes 14 bored around the upper edge of the accommodating chamber 11.
  • Each combining hole 13 has a broad portion 131 and a slender portion 132 extended outward from the broad portion 131.
  • the slender portion 132 is extended outward from the broad portion 131, with the first connector 12 utilized as a center.
  • bored around the upper circumference of the accommodating chamber 11 are plural restricting holes 14.
  • the lighting module 20 is installed in the accommodating chamber 11 of the lamp base 10, provided with a lamp hood 21, at least a flexible member 22, a base board 23 and plural fixing devices 24.
  • the above components are to be described with reference to Figs. 2 and 3 .
  • the lamp hood 21 is provided with plural first engaging members 211 corresponding to the combining holes 13 of the lamp base 10, and at least a positioning bar 212 located near each of the first engaging members 211.
  • the first engaging members 211 are threaded holes, with two sides of each first engaging member 211 respectively having one positioning bar 212.
  • the flexible member 22 is deposited at one side of the first engaging member 211.
  • each first engaging member 211 of the lighting module 20 is engaged with one flexible member 22, which is formed as a plate spring.
  • the flexible member 22 is provided with a through hole 221 bored in the center to correspond to the first engaging member 211, and two positioning holes 222 correspondingly inserted in the positioning bars 212 to fix the flexible member 22 under the lamp hood 21.
  • the flexible member 22 has two ends flatly curved outward to form as leaning tips 223.
  • the base board 23 is elastically pressed by the flexible members 22, provided with plural LEDs 231 deployed like a vortex, a second connector 232 connected with the first connector 12 of the lamp base 10 to electrify the LEDs 231, a through hole 233 corresponding to each first engaging member 211, and a heat disperser 234 installed at one side opposite to the lamp hood 21.
  • the fixing members 24 are respectively inserted in the through holes 233, with one end formed as a second engaging member 241 to fixedly engage with the first engaging member 211.
  • the second engaging member 241 is a male-threaded bar.
  • the fixing members 24 have another end extended out of the through hole 233 to expansively form as a head 242.
  • the easily collapsible LED bulb 100 is provided with a transparent covering 30, which has plural locking projections 31 built on the circumference to correspondingly interlock with the restricting holes 14, so that the transparent covering 30 can be fixed on the lamp base 10 to position outside the accommodating chamber 11.
  • Figs. 4 and 5 show how to assemble and disassemble the easily collapsible LED bulb 100 of the invention.
  • the lighting module 20 is first fixed on the lamp base 10, with the heads 242 of the fixing members 24 inserted through the broad portions 131 of the combining holes 13; next, the lighting module 20 is turned around to enable the heads 242 to move to be restricted in the slender portions 132, making the lighting module 20 fixed on the lamp base 10; then the first connector 12 is connected with the second connector 232 so as to drive LED lit up.
  • the lighting module 20 when the lighting module 20 is turned around reversely to enable the heads 242 of the fixing members 24 to move to the broad portion 131, it can be removed from the lamp base 10, with the power adapter and the driving circuit module that are comparatively pricy and durable installed in the lamp base 10 and electrically connected with the first connector 12.
  • the lighting module 20 it is just necessary to replace the lighting module 20 with a new one in case of merely damage of LEDs 231 of the base board 23, without necessity of discarding the whole easily collapsible LED bulb 100. So the invention is really eco-friendly and economic.
