Patents Act 1990 INNOVATION SPECIFICATION FOR AN INVENTION ENTITLED Invention title: Name of Applicant: Address for Service Lamp Structure Che-Kai Chen, Yao-Hung Wong, Sam Wu A.P.T. Patent and Trade Mark Attorneys PO Box 222 Mitcham, S.A. 5062 The invention is described in the following statement: 00 LAMP STRUCTURE BACKGROUND OF THE INNOVATION Field of the Innovation The present innovation relates to a lamp structure, and more particularly to a lamp structure with focused bright light, its illumination angle is as large as 180 degrees, and the lamp has a long life, good heat dissipation and is environmental friendly.

00 F Description of the Prior Art Conventional lights, not matter wall or ceiling type, are all big in size and occupy a lot space. On top of that, if the light itself doesn't have an appealing appearance and a well-designed shape, it can't be in harmony with the surrounding decorations.

The present innovation has arisen to mitigate and/or obviate the afore-described disadvantages.

For the purposes of this specification the word "comprising" means "including but not limited to", and the word "comprises" has a corresponding meaning. Also a reference within this specification to a document is not to be taken as an admission that the disclosure therein constitutes common general knowledge in Australia.

SUMMARY OF THE INNOVATION The primary objective of the present innovation is to provide a lamp structure with focused bright light, its illumination angle is as large as 180 degrees, and the lamp has a long life, good heat dissipation and is environmental friendly.

To achieve the above objective, the lamp structure provided in accordance with the present innovation comprises: a slim light emitting source including at least one light emitting diode packaged on a 00 S multilayered printed circuit board type aluminum base; a funnel-shaped reflector being concaved toward a center thereof, in a bottom of the j reflector being defined at least one hole for partially accommodating a surface of the light emitting 0 diode, and an inner surface of the reflector being coated to form a light reflecting surface; a flat lens whose surface being treated with sand blast; 0 0 a lamp housing including a receiving chamber, one end of which being accommodated 00 S with the slim light emitting source, the reflector, and the flat lens, respectively, and the other end of which being provided for insertion of a driver, an outer surface of the lamp housing being formed with a plurality of heat dissipation fins; and the driver being inserted in the other end of the receiving chamber of the lamp and having a positive and negative leads connected to the slim light emitting source for making it produce light.

The light emitting diode is any color and is high power.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is an exploded view of a lamp structure in accordance with a preferred embodiment of the present innovation; Fig. 2 is a perspective view of the lamp structure in accordance with the preferred embodiment of the present innovation; Fig. 3 is a cross sectional view of the lamp structure in accordance with the preferred embodiment of the present innovation; and Fig. 4 is another cross sectional view of the lamp structure in accordance with the preferred embodiment of the present innovation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 00 0 The present innovation will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present innovation.

Referring to Fig. 1, which is an exploded view of a lamp structure in accordance with a preferred embodiment of the present innovation. The lamp structure comprises: a slim light emitting source 1, a reflector 2, a flat lens 3, a lamp housing 4 and a driver 00 The light emitting source 1 includes one or more high power LED (light emitting diode) packaged on a MPCB (multilayered printed circuit board) aluminum base 11, and the LED can be any color. Around the periphery of the aluminum base 11 are oppositely arranged two locking grooves 12 for passage and electrical connection of the positive and negative leads 50 of the driver 5 and a plurality of gaps 13 for making it easier to take out the light emitting source 1 from the lamp housing 4 when replacement is required.

The reflector 2 is funnel-shaped and concaved toward the center thereof, in the bottom of the reflector 2 are defined one or more holes 20 for accommodation of a part of the surface of the LED 10, and the inner surface of the reflector 2 is coated to form a light reflecting surface for adjusting the illumination angle, eliminating shade, and focusing the light generated from the light source while preventing waste of light.

The surface of the flat lens 3 is treated with sand blast to blend the light source and carry out luminous reflectance, so that the illumination angle can be adjusted up to 180 degrees, ghosting is prevented, and the light source is emitted out in a focused way.

The lamp housing 4 includes a receiving chamber 40, one end of which is accommodated with the slim light emitting source 1, the reflector 2, and the flat lens 13, respectively, and the other end of which is provided for insertion of the driver 50. The outer surface of the lamp housing 4 is 00 0 formed with a plurality of heat dissipation fins 41.

The driver 5 is inserted in the other end of the lamp 4 and has positive and negative leads 50 connected to the slim light emitting source 1 for making it to produce light.

As shown in Fig. 2, which is a perspective view of a lamp structure in accordance with the preferred embodiment of the present innovation, the light emitting source 1 is inserted in the S receiving chamber 40 of the lamp housing 4, and then the reflector 2 is inserted with its holes 00 O aligned and engaged with the LEDs 10. After that, the flat lens 3 is assembled, and then the driver is inserted into the other end of the receiving chamber 40 with its positive and negative leads extending into electrical contact with the light emitting source 1, as shown in Figs. 3 and 4, thus forming a lamp.

When in use, the operating voltage of the lamp is 12 V, and because of the high power LEDs 10, the light emitting source 1 will produce bright enough light and has a long life. On top of that, the reflector 2 can adjust the illumination angle of the LEDs 10, illuminate shade, and focus the light of the light emitting source. Furthermore, the sand blasted flat lens 3 can blend the light emitting source to have an illumination angle of 180 degrees, and thus ghosting is prevented.

Finally, the fins 41 around the outer periphery of the lamp housing 4 can effectively improve the heat dissipation efficiency.

While we have shown and described various embodiments in accordance with the present innovation, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present innovation.
