Description
TECHNICAL FIELD
[0001] The present invention relates to the field of illumination
devices and particularly to a radiator for an LED lamp.
BACKGROUND
[0002] 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
[0003] 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.
[0004] 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
[0005] 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:
[0006] FIG. 1 is a side view of an LED lamp radiator;
[0007] FIG. 2 is an exploded view of the LED lamp radiator;
[0008] FIG. 3 is an isometric view of the LED lamp radiator;
[0009] FIG. 4 is a cross-sectional view of the LED lamp
radiator;
[0010] FIG. 5 is a top view of the LED lamp radiator with a support
plate installed; and
[0011] FIG. 6 is a bottom view of the LED lamp radiator with the
support plate installed.
DETAILED DESCRIPTION
[0012] Reference will now be made in detail to the presently
preferred embodiments of the invention, examples of which are
illustrated in the accompanying drawings.
[0013] 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.
[0014] 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.
[0015] 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.
[0016] 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.
[0017] 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.
[0018] 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.
