`
`ABSTRACT
`
`A heat sink device for configuring a lamp house is disclosed.
`The heat sink device includes a heat sink and a lamp house.
`The lamp house is telescoped into the heat sink. The heat
`sink includes room for containing a heat condition material.
`The lamp house is used for configuring an light emitting
`device. The heat sink comprises a plurality of fins surround
`itself. The heat generated by the light emitting device can be
`dissipated into the air via the heat condition material and the
`fins.

`
`LAMP HOUSE WITH HEAT SINK
`
`BACKGROUND UE THE INVENTION
`
`[0001]
`
`1. Field of the lnve11tio11
`
`[0002] The present invention generally relates to a heat
`sink, and more particularly to the heat sink configured on a
`lamp house.
`[0003]
`2. Description of the Prior Art
`
`[0004] Light emitting diode has the excellence of l1igh
`brightness, low power consumption.
`long lifetime. a11dlow
`temperature. Comparing to the drawbacks of the traditional
`lan1p. it is a breakthrough. For examples, the light emitting
`diode can be used on a llashlight over 50 hours with 3 ‘AAA
`batteries. Some excellent light emitting diodes can further
`used over 70 hours. Namely, the light emitting diodes have
`very excellent elficiency of power consumption.
`[0005] For enhancing the brightness, the light emitting
`diodes are designed to have better illumination. Although
`the light emitting diodes are low power consumption, it still
`can not avoid generating a lot of heat within a limited space
`for better illumination. The heat will age or damage the other
`components in the surroundings. Therefore a better design
`for dissipating the heat.
`
`SUMMARY OF THE INVFNTION
`
`[0006] Therefore, in accordance With the previous sum­
`mary. objects. features a11dadvantages of the present dis­
`closure will become apparent to one skilled in the art from
`the subsequent description and the appended claims taken in
`conjunction with the accompanying drawings.
`
`[0007] A l1eatsink device for configuring a lamp house is
`disclosed. The heat sink device includes a heat sink and a
`lan1p house. The lan1phouse is telescoped into the heat sink.
`The heat sink includes room for containing a heat condition
`material. The lamp house is used for configuring a light
`emitting device. The heat sink comprises a plurality of fins
`surround itself. The heat generated by the light emitting
`device can be dissipated into the air via the heat condition
`material and the fins.
`
`BRIEF DESCRIPTION OF THE DRAVVINGS
`
`[0008] The accompanying drawings incorporated in and
`for111inga part of the specification illustrate several aspects
`of the present invention, and together With the description
`serve to explain the principles of the disclosure. In the
`drawing s:
`
`FIG. 1 is a diagram illustrates the structure of the
`[0009]
`lamp house with a heat sink according to one embodiment
`of the present invention;
`
`FIG. 2 a11dFIG. 3 are the side profiles of the lamp
`[0010]
`house with a heat sink; and
`
`[0011] FIG. 4 is a diagram shows the lamp house with a
`heat sink.
`
`DETAILED DESCRIPTION OF TIIE
`PREFERRED EMBODIMENTS
`
`[0012] The present disclosure can be described by the
`embodiments given below. It is understood, however, that
`
`the embodiments below are not necessarily limitations to the
`present disclosure, but are used to a typical implementation
`of the invention.
`
`[0013] Having summarized various aspects of the present
`invention, reference will now be made in detail to the
`description of the invention as illustrated in the drawings.
`\Vhile the invention will be described in connection with
`these drawings,
`there is no intent
`to li111itit to the e111bodi­
`ment or embodiments disclosed therein. On the contrary the
`intent is to cover all alternatives. modifications and equiva­
`lents included within the spirit a11dscope of the invention as
`defined by the appended claims.
`
`It is noted that the drawings presents herein have
`[0014]
`been provided to illustrate certain features and aspects of
`embodiments of the invention. It will be appreciated from
`the description provided herein that a variety of alternative
`embodiments and implementations may be realized. consis­
`tent with the scope and spirit of the present invention.
`
`It is also noted that the drawings presents herein are
`[0015]
`not consistent with the same scale. Some scales of some
`components are not proportional
`to the scales of other
`components in order to provide comprehensive descriptions
`and emphasizes to this present invention.
`
`l-‘IG. 1 illustrates the structure of the lan1p house
`[0016]
`with a heat sink according to one embodiment of the present
`invention. The lamp house with a heat sink comprises a heat
`sink base 10 and a lan1phouse 30. The heat sink base 10 has
`a first cup structure 16 which is inward hollow. The bottom
`of the first cup structure 16 comprises at least a first hole 12.
`The heat sink base 10 can comprise a plurality of fins 18,
`wherein the first cup structure 16 is circularly surrounded by
`the fins 18. Furthermore, lamp house 30 has a second cup
`structure 36 which is inward hollow. The second cup struc­
`ture 36 comprises at least a second hole 32 and is telescoped
`i11tosaid heat sink base 10.
`
`[0017] Referring to l-‘IG.2, heat sink 10 has closed space
`20. The closed space 20 can be a ringlike space surrounded
`by a plLu"alityof fins. The shape of the closed space 20 can
`also be like a cup. Besides, the closed space 20 circularly
`surrounds the first hole 12. The embodiment further com­
`prises a heat conduction material (not shown in the figures)
`within the closed space 2|). The heat conduction material can
`be injected into the closed space 20 through a hole. After
`injecting, the hole can sealed to fonn the closed space 20.
`
`[0018] Referring to FIG. 3. the embodiment can further
`comprises a light emitting device 40 configured on said
`second hole 32. The light emitted device 40 comprises at
`least a wire. wherein each wire goes through one of the first
`holes 12 and one of the second holes 32. Moreover, the light
`emitting device 40 can further comprises the relative circuit
`components. i.e. the printed circuit board. Furthermore. the
`bottom of the first cup structure can ftmher comprise a base
`which can be an inward hollow area for configuring with the
`relative circuit components of the light emitting device 40.
`
`[0019] Accordingly. referring to PIG. 4, the ligl1temitting
`device 40 inside the lamp house 30 ca11get
`the electric
`power or control signals outside the lamp house via the wires
`42 when the heat sink base 10 and lan1p house 30 are
`teleseoped. Besides, the heat can be conducted to the fins via
`the heat conduction material, thereby the heat can be dissi­
`pated well.

`holloW,Wherein said second cup structure comprises at
`
`lcast a sccond holc and is tclcscopcd into said hcat sink
`basc.

`2. A lamp house With a heat sink of claim 1, Wherein said
`hcat sink basc compriscs a plurality of fins.
`3. A lamp house With a heat sink of claim 2, Wherein said
`first cup structurc is circularly surroundcd by said fins.
`4. A lamp house With a heat sink of claim 3, Wherein said
`closcd spacc is a ringlikc spacc circularly surrounded by said
`fins.
`
`5. A lamp house With a heat sink of claim 1, Wherein the
`configuration of said closcd spacc is likc a cup and said
`closed space circularly surrounds said first hole.
`turthcr
`6. A lamp housc with a hcat sink of claim l,
`comprising a heat conduction material within said closed
`space.
`turthcr
`7. A lamp housc with a hcat sink of claim l,
`comprising a light emitting device configured o11said second
`hole.
`
`8. A la111phouse With a heat sink ofclaim 7, wherein said
`light cmittcd dcvicc compriscs at lcast a Wirc, Whcrcin cach
`Wire goes through one of said first holes and one of said
`second holes.
`9. A lamp house With a heat sink of claim 8, Wherein the
`bottom of said first cup structure comprises an inward
