Definitions

  • the present invention relates to a light emitting diode (LED) lamp, especially to an energy efficient high intensity reflector lamp that features on reduced volume and enhanced heat dissipation property.
  • LED light emitting diode
  • a conventional reflector lamp includes a light emitting diode (LED) 61 disposed on a light emitting diode (LED) unit 60.
  • the LED unit 60 is also arranged with a driving electronic 62 and is connected to a heat conducting portion 63 for heat dissipation.
  • the LED unit 60 is further connected to a LED driver 64 and the LED driver 64 is fastened on a driver's heat dissipation portion 65 so as to dissipate heat generated. All the components mentioned above are mounted and positioned in a clamp 70 and then is set into a housing 80.
  • a lens unit 81 and a front cover 82 are covered over an opening of the housing 60.
  • Both the LED unit 60 and the LED driver 64 are disc-like circuit boards being disposed with a lot of electronics. Thus they have larger volume and occupy more space. Therefore the space of the housing 80 needs to be increased in order to receive the LED unit 60 and the LED driver 64. The total volume of the device is too large.
  • the LED 61 and the driving electronic 62 are assembled on the same LED unit 60. While in use, the LED 61 generates a lot of heat that is directly conducted to the driving electronic 62. Thus the driving electronic 62 is easy to get damaged due to overheat.
  • the LED unit 60 also has bad heat dissipation.
  • the reflector lamp includes an integrally formed aluminum shade disposed with a plurality of heat dissipation fins, a round plate, a reflector installed on top of the shade, a housing disposed with inclined locking blocks and stopping strips, and an electronic device.
  • the shade includes a heat dissipation channel communicating an inner side and an outer side thereof, a circular groove disposed close to the bottom end thereof, at least one stopping slot arranged axially and a mounting portion close to the top end thereof.
  • An outer edge of the round plate is tightly riveted onto the mounting portion of the shade and a LED light is disposed on a front surface of the round plate.
  • the reflector is installed on top of the shade. A plurality of inclined locking blocks and a plurality of stopping strips are projected from a surface of the housing.
  • the housing is mounted into and fixed on the shade by the stopping strip inserted into the stopping slot and the inclined locking blocks locked into the circular groove of the shade. And the shade is only in contact with the housing at the inclined locking blocks.
  • the electronic device is formed by a main circuit board and at least one secondary circuit board while the secondary circuit board is disposed on the main circuit board perpendicularly. Thus the electronic device is able to be mounted in the housing and used to control the LED light.
  • external threads are formed on the heat dissipation fins and are around a top end of the shade while the reflector is positioned by a fixing ring.
  • the fixing ring is disposed with internal threads on an inner edge thereof.
  • the fixing ring is fastened on the heat dissipation fins by the internal threads engaged with the external threads.
  • An adhesive sealant is filled between the round plate and the LED light.
  • At least one slot is arranged at the main circuit board of the main circuit board.
  • a plurality of electric contacts is disposed projectingly on a surface of the housing while the electronic device is connected to the electric contacts.
  • An adhesive sealant is filled inside the housing.
  • the electronic device is connected to a protective capacitor.
  • One end of the protective capacitor and the electronic device are conducted to each other while the other end of the protective capacitor is connected to a wire.
  • the wire is clipped between the housing and the shade.
  • the protective capacitor conducts the high voltage current to the shade to form a test loop, without passing the LED light.
  • the protective capacitor prevents the high voltage current from flowing through the LED light, working as high voltage shielding.
  • the electronic device is connected to a magnetic reluctance that eliminates noises.
  • the space in the housing is filled with the adhesive sealant for covering and positioning the electronic device.
  • the heat dissipation of the electronic device is also improved by heat conduction of the adhesive sealant.
  • sulfuration of the electronic device is also eliminated due to vacuum state formed by the adhesive sealant.
  • a plurality of heat dissipation fins is arranged circularly around the tubular shade.
  • the heat dissipation of the shade is further improved by the heat dissipation channel that is communicating an inner side and an outer side of the shade.
  • an energy efficient high intensity reflector lamp of the present invention includes a shade 10, a round plate 20, a reflector 30, a housing 40, and an electronic device 50.
  • the shade 10 is integrally formed and made from aluminum.
  • a plurality of heat dissipation fins 11 is arranged circularly around the tubular shade 10 and a heat dissipation channel 12 communicating an inner side and an outer side of the shade10 is disposed circularly around the tubular shade 10.
  • the heat dissipation effect of the shade 10 is increased by the heat dissipation fins 11 and the heat dissipation channel 12.
  • External threads 111 are formed on the heat dissipation fins 11 and are around a top end of the shade 10.
  • a circular groove 13 is mounted inside the shade 10, close to the bottom end of the shade 10 while at least one stopping slot 14 is axially arranged in the shade 10.
  • a mounting portion 15 is formed adjacent to the top end of the shade 10.
  • An outer edge of the round plate 20 is tightly riveted onto the mounting portion 15 of the shade 10 and a LED light 21 is disposed on a front surface of the round plate 20.
  • An adhesive sealant 22 is arranged between the round plate 20 and the LED light 21 to fill pores therebetween and enhance heat conduction and dissipation.
  • the reflector 30 is installed on top of the shade 10 so that light from the LED light 21 is converged and emitted out.
  • a fixing ring 31 is used to position the reflector 30 and is disposed with internal threads 311 on an inner edge thereof.
  • the internal threads 311 of the fixing ring 31 are engaged with the external threads 111 of the heat dissipation fins 11.
  • a plurality of inclined locking blocks 41 and a plurality of stopping strips 42 are projected from a surface of the housing 40. After the housing 40 being mounted into the shade 10, the stopping strip 42 is inserted into the stopping slot 14 for preventing the shade 10 and the housing 40 from rotating.
  • the inclined locking blocks 41 are pressed and locked into the circular groove 13 of the shade 10. Thus the shade 10 is only in contact with the housing 40 at the inclined locking blocks 41 so as to block heat conduction effectively.
  • a plurality of electric contacts 43 is disposed projectingly on the surface of the housing 40.
  • the electronic device 50 having a main circuit board 51 and at least one secondary circuit board 52, is connected to the electric contacts 43. There is at least one slot 511 on the main circuit board 51 for providing electrical isolation.
  • the secondary circuit board 52 is arranged at the main circuit board 51 perpendicularly so as to reduce the volume of the electronic device 50.
  • the electronic device 50 can be mounted in the housing 40 for control of the LED light 21.
  • An inner space of the housing 40 is filled with an adhesive sealant 44 and the adhesive sealant 44 is used for positioning and improving heat dissipation of the electronic device 50.
  • the electronic device 50 is in vacuum insulation due to the adhesive sealant 44.
  • capacitor electrolyte is unable to evaporate and sulfuration of the electronic device 50 will not occur. Therefore the service life is extended.
  • the structure mentioned above not only reduces overall volume but also improves heat dissipation.
  • the electronic device 50 is connected to the electric contacts 43 of the housing 40. Due to perpendicular design of the main circuit board 51 to the secondary circuit board 52, the volume of the electronic device 50 is reduced and is able to be mounted into the housing 40 easily. Then the electronic device 50 is vacuum sealed by the adhesive sealant 44 filled in the housing 40. Thus the electronic device 50 is not only fixed firmly, the heat dissipation thereof is effectively improved and the sulfuration is minimized. Next the housing is arranged into the shade 10. The rotation of both the housing 40 and the shade 10 is prevented by the stopping strips 42 of the housing 40 and the stopping slot 14 of the shade 10.
  • the housing 40 and the shade 10 are in a partial contact and are fixed.
  • the electronic device 50 is electrically connected to the LED light 21 of the round plate 20.
  • the electrical contact 43 and the LED light 21 are electrically connected and the LED light 21 is controlled by the electronic device 50.
  • the round plate 20 is fixed on the mounting portion 15 of the shade 10 by rivets.
  • the reflector 30 is arranged in front of the LED light 21 in the shade 10 and is fixed by the internal threads 311 of the reflector 30 engaged with the external threads 111 of the heat dissipation fins 11. Thus light from the LED light 21 is concentrated and emitted.
  • the structure mentioned above has following advantages: (1) The secondary circuit board 52 of the electronic device 50 is disposed on the main circuit board 51 in the direction perpendicular to the main circuit board 51. Thus the volume of electronic device 50 is reduced and is able to be mounted into the housing smoothly. The overall volume of the reflector lamp is decreased. (2) After receiving the electronic device 50, the housing is filled with the adhesive sealant 44 so as to cover and position the electronic device 50. Moreover, the heat dissipation of the electronic device 50 is enhanced due to heat conduction of the adhesive sealant 44. The sulfuration of the electronic device 50 is also minimized due to the vacuum state formed by the adhesive sealant 44. (3) The housing 40 is assembled with the shade 10 by the inclined locking blocks 41 being pressed and locked into the circular groove 13.
  • the round plate 20 is riveted and fixed on the mounting portion 15 of the shade 10.
  • the internal threads 311 of the reflector 30 are engaged with the external threads 111 of the heat dissipation fins 11 of the shade 10.
  • the assembly is fast and non-contact.
  • the value added is increased.
  • the rotation of both the housing 40 and the shade 10 is prevented by the stopping strips 42 of the housing 40 connected to the stopping slot 14 of the shade 10.
  • the housing 40 and the shade 10 are in a partial contact by the inclined locking blocks 41 of the housing 40 being pressed and locked into the circular groove 13 of the shade 10.
  • the electronic device 50 will not be affected by high temperature of the end with the LED light 21 and having higher durability.
  • the tubular shade 10 is integrally formed, made from aluminum and having a plurality of heat dissipation fins 11 therearound. Air flows through the space between the hollowed-out heat dissipation fins 11 so as to dissipate heat more effectively. Moreover, the heat dissipation of the shade 10 is further improved by the heat dissipation channel 12 that is communicating an inner side and an outer side of the shade 10. (6) The adhesive sealant 22 between the round plate 20 and the LED light 21 fills pores therebetween to improve heat conduction and dissipation therebetween.
  • the electronic device 50 is connected to a magnetic reluctance 53 that eliminates noises.
  • the magnetic reluctance 53 noises of the current flowing from the electric contact 43 and the electronic device 50 are filtered and eliminated so as to improve the stability in use.
  • the LED light 21 is fixed on the round plate 20 with high thermal conductivity so that the working temperature of the LED light 21 is significantly decreased. Once the insulation strength is not enough, high voltage current easily enables a spark jumps from the LED light 21 to the shape 10 and this lead to damages of the LED light 21 while performing high voltage insulation test The lamp is also unable to pass the high voltage test.
  • the electronic device 50 is connected to a protective capacitor 54.
  • One end of the protective capacitor 54 and the electronic device 50 are conducted to each other while the other end of the protective capacitor 54 is connected to a wire 541.
  • the wire 541 is clipped between the housing 40 and the shade 10.
  • the capacitance of the protective capacitor 54 is at least five times than larger the total capacitance of the electronic device 50.
  • the capacitor 54 is an open circuit and has no effect on use and control of the LED light 21.
  • the protective capacitor 54 conducts the high voltage current to the shade 10 to form a test loop, without passing the LED light 21.
  • the protective capacitor 54 prevents the high voltage current from flowing through the LED light 21, working as high voltage shielding.
  • the LED light 21 is protected by the protective capacitor 54 and the safety requirements are met.
