Description

    TECHNICAL FIELD
  • The present invention relates to the field of illumination devices and particularly to a radiator for an LED lamp.
  • BACKGROUND
  • A light-emitting diode (LED) is a semiconductor light source. LEDs may present many advantages (e.g., lower energy consumption and smaller size) over other light sources. LEDs may therefore be utilized as efficient light sources in fields such as automobiles, traffic lights, screen displays, general illumination, and the like. However, as the power of the LED increases, the amount of heat generated also increases. Heat generated in operation may cause the temperature of the LED to rise. The LED may burn out when the temperature exceeds a certain level.
  • SUMMARY
  • Accordingly, an embodiment of the present disclosure is directed to an LED lamp radiator. The LED lamp radiator may comprise a generally ring-shaped upper base member having a first outer diameter; a generally ring-shaped lower base member having a second outer diameter substantially identical to the first outer diameter; a plurality of fins fixedly attached to the upper base member and the lower base member, forming a generally cylindrical shape. Each of the plurality of fins has an upper portion, a middle portion and a lower portion, the upper portion being fixedly attached to a periphery of the upper base member, the lower portion being fixedly attached to a periphery of the lower base member, and the middle portion being configured for physically separating the upper base member and the lower base member. The LED lamp radiator may further comprise a support plate removably secured to the upper base member, the support plate configured for supporting an LED lamp within the generally cylindrical shape formed by the upper base member, the lower base member and the plurality of fins.
  • It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not necessarily restrictive of the invention as claimed. The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and together with the general description, serve to explain the principles of the invention.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • The numerous advantages of the present invention may be better understood by those skilled in the art by reference to the accompanying figures in which:
  • FIG. 1 is a side view of an LED lamp radiator;
  • FIG. 2 is an exploded view of the LED lamp radiator;
  • FIG. 3 is an isometric view of the LED lamp radiator;
  • FIG. 4 is a cross-sectional view of the LED lamp radiator;
  • FIG. 5 is a top view of the LED lamp radiator with a support plate installed; and
  • FIG. 6 is a bottom view of the LED lamp radiator with the support plate installed.
  • DETAILED DESCRIPTION
  • Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.
  • Heat generated during an operation of an LED may cause the temperature of the LED to rise. The LED may burn out when the temperature exceeds a certain level. Therefore, it may be appreciated to quickly transfer and/or emit the heat generated in order to improve the quality of illumination and service life of the LED.
  • Referring generally to FIGS. 1 through 6, a radiator 100 for an LED lamp is shown. It may be appreciated that, different from conventional radiators that distributes heat by conduction, the radiator 100 of the present disclosure improves the efficiency of the radiator by increasing airflow and enhancing heat dissipation performances. Furthermore, the radiator 100 of the present disclosure may also reduce material consumptions and/or per unit costs.
  • The radiator 100 comprises a generally ring-shaped upper base member 102, a generally ring-shaped lower base member 104 and a plurality of fins 106. The upper base member 102 may have a first outer diameter that is substantially identical to a second outer diameter of the lower base member 104. The fins 106 are fixedly attached to the upper base member and the lower base member, forming a generally cylindrical shape. In one embodiment, the plurality of fins 106 may be evenly spaced apart from each other. In addition, the plurality of fins 106 may be at least partially curved.
  • Each one of the plurality of fins 106 includes an upper portion 108, a middle portion 110 and a lower portion 112 (as illustrated in FIG. 4). The upper portion 108 of each fin 106 is fixedly attached to the periphery (e.g., outer edge surface) of the upper base member 102. Similarly, the lower portion 112 of each fin 106 is fixedly attached to the periphery (e.g., outer edge surface) of the lower base member 104. The middle portion 110 of each fin 106 has a predetermined length greater than zero, therefore providing a separation between the upper base member 102 and the lower base member 104.
  • The radiator 100 further comprises a support plate 114 for supporting an LED lamp within the radiator 100. For example, the support plate 114 may be configured for supporting the LED lamp within the generally cylindrical shape formed by the upper base member 102, the lower base member 104 and the plurality of fins 106. In one embodiment, the support plate 114 is a generally rectangular plate removably secured to the upper base member 102. The support plate 114 may include two screw holes 116 at which the LED lamp may be mounted to. It is understood that various other fastening means such as snap-fit clips, bolt joints, clamps and the like may be utilized without departing from the spirit and scope of the present disclosure. It is also understood that the upper base member 102 may have keyways 118 defined for receiving the support plate 114. It is also contemplated that the inner surface of the generally ring-shaped upper base member 102 may be threaded (as illustrated in FIGS. 2 through 4) to facilitate mounting of the radiator 100 to other devices.
  • It is believed that the present invention and many of its attendant advantages will be understood by the foregoing description. It is also believed that it will be apparent that various changes may be made in the form, construction and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages. The form herein before described being merely an explanatory embodiment thereof, it is the intention of the following claims to encompass and include such changes.
