The present invention is related to an LED lighting fixture, and more particularly to a high brightness lighting fixture with compact size and enhanced cooling effect.
A structure of spotlight, characterized in the LED 61 is assembled on the LED unit structure 60, which the LED unit structure 60 has driving electronic device 62, and the LED unit structure 60 connects to heat conducting part 63 to cool the heat. Furthermore, the LED unit structure 60 connects to the LED driving device 64, which LED driving device lock sets cooling part of driving device 65 to cool the heat. Above-mentioned units all set at clamp 70 and fixed, and are put into housing 80 by clamp 70. Lens unit 81 and front panel 82 cover housing 80 to make its composition, and LED 61's light penetrates lens unit 81 projecting. However, above-mentioned structure still has some problems can be improved, these are the main problems: 1. The LED unit structure 60 and LED driving device 64 are both circular circuit board, which is used to provide a large amount of electronic unit composition, and has bigger volume, it makes housing 80 needs to be bigger to set LED unit structure 60 and LED driving device 64 inside. It has the obvious problem that the product is not small enough. 2. LED 61 and driving electronic device 62 are set at same LED unit structure 60. When using LED 61 will generate a large amount heat and conduct to driving electronic device 62 directly, it makes driving electronic device 62 easier to damage by overheating, also, the LED unit structure 60 can cool down efficient, which makes the problem of undesired cooling effect. 3. LED unit structure 60 and LED driving device 64 are both exposed to the air. It causes the problems of unstable structure and effect of sulfation, which affect its durability. 4. LED unit structure 60 and LED driving device 64 are separately connect to heat conducting part 63 and cooling part of driving device 65 to cool down. However, the cooling structure is fully covered by housing 80, lens unit 82 and front panel 82. It makes the high temperature air cannot convective heat transfer. Furthermore, heat conducting part 63 and cooling part of driving device 65 has not enough cooling area, and LED 61 does not have LED driving device 64 to make effective heat barrier. It causes the whole structure overheated and might make LED driving device 64 damages, which has the problem of cooling down.
Therefore, there remains a need for a new and improved LED lighting device to overcome the problems stated above.
To solve the problems stated above, the present invention provides an energy-saving and high-brightness lighting fixture.
The energy-saving and high-brightness lighting fixture may include an integrally molded aluminum light cover, which is tubular with plurality of heat sinks on outer ring, and outside the connected light cover has a cooling tank, wherein, inside the light cover has a ring groove transverse, at least a restricting groove longitudinal. The ring groove near the bottom of light cover, an engaging portion is at the top of the light cover. A circular plate is riveted with light cover's engaging portion, and a LED lamp set on it. A light-collecting lens is set on the top of the light cover. A housing body's surface with fixture block and plurality limiting strip, which housing body is inserted in the restricting groove by limiting strip and using fixture block to fix at ring groove of light cover, it makes the light cover only contact with fixture block and housing. An electronic device is composed by a main circuit board and at least one auxiliary circuit board, and the auxiliary circuit board is vertically set on main circuit board, it makes electronic device can be set inside the light cover and control LED lamp.
In one embodiment, heat sink on the top of the housing has outer thread outside, and the light collecting lens is fixed by a fixed ring, which the fixed ring has a inner thread inside to make fixed ring can lock set with heat sink's outer thread.
In another embodiment, the circular plate stick LED lamps with adhesive strip. In still another embodiment, the electronic device on main circuit board has a groove, and the surface of the housing has plurality electrical connection contact points, and the electronic device contacts with these electrical connection contact points.
In a further embodiment, the housing is filled with adhesive strip inside. In still a further embodiment, the electronic device contacts with protection capacitance, and the protection capacitance conducts with electronic device output point on one side and contact with wire on the other side. The wire sets between housing and light cover. Doing the test of high voltage insulation resistance, the high voltage current can come around LED lamp have conducting loop with protection capacitance. It has high voltage insulation function and protect LED lamp.
In still a further embodiment, the electronic device connects with a magnetic resistance to eliminate noise.
The main objective of the present invention is making auxiliary circuit board vertically disposed on the main circuit board to decrease the volume of the electronic device, so the electronic device can be inserted into housing to decrease the volume of the product.
The second objective of the present invention is to provide space for the electronic device inside the housing and filled the housing with adhesive strip, which can make electronic device covered by adhesive strip and fixed. Furthermore, using adhesive strip's heat conduction to enhance the cooling effect of electronic device and using vacuum state to eliminate sulfation of electronic device.
The third objective of the present invention is that the housing is fixed at light cover's ring groove through the fixture block, and the circular plate is riveted at light cover's engaging portion, moreover, the fixing ring is set at heat sink's outer thread by inner thread, which can compose the structure faster and make a composition without contact point, and increase the product's additional value.
The forth objective of the present invention is that the housing's limiting strip combine with light cover's restricting groove and make anti-rotation effect. The housing is fixed at light cover's ring groove by fixture block, which can make housing and light cover partly contact with fixture block, it can decrease a lot contact area and have great heat insulation effect, so the electronic device will not be affected by the LED lamp's heat to increase its durability.
The fifth objective of the present invention is that an integrally molded aluminum light cover, which is tubular with plurality of hollow heat sinks on outer ring, it can make air follow through these heat sinks, also, the light cover contact with cooling tank, it can enhance the cooling effect of light cover.
The sixth objective of the present invention is that the circular plate contacts LED lamps with adhesive strip, filling their pores to enhance heat conduction effect.
