Patent Application
20070165412
The present invention relates to a light-emitting-diode (LED) light holder assembly, which can be easily mounted to and removed from a lighting fixture to allow the use of an LED light as a light source for lighting fixtures.
Incandescent bulbs, quartz bulbs, fluorescent bulbs, and mercury lamps are most frequently used on daily lighting fixtures as light sources. All these bulbs or lamps are not adjustable to change the light projecting directions thereof once they are installed on the lighting fixtures. Therefore, a user has to take the areas to be illuminated into consideration at the very beginning of mounting the lighting fixtures. When it is desired to project the light of a lighting fixture to different illuminating areas, the user has only one choice, that is, to change the mounting position of the lighting fixture. To do so, the user might have to troublesomely re-arrange the wires for the lighting fixture or drill new or additional holes on walls or ceilings.
The light-emitting diode (LED) has the advantages of low power consumption, high illuminating efficiency, and small volume, and is frequently used as an indicator light in a circuit. Later, LED lights are also frequently used on large-scale electronic advertising signboards and traffic signal lamps, particularly the signal lamps at pedestrian crosswalks. Recently, the LED lights have also been used on lamps of some high class cars as light sources. In all the above-mentioned applications of LED lights, the LED lights are fixedly welded to a circuit board of a lighting appliance. In the event any one of the LED lights on the circuit board is damaged, the whole lighting appliance must be replaced with a new one to show perfect lighting effect. It is apparently not economical to discard the non-damaged LED lights on the circuit board of the lighting appliance. That is why one may frequently find many advertising signboards and traffic signal lamps showing incompletely illuminated areas due to some damaged LED lights thereof. For these reasons, the LED lights have not yet been widely used on most lighting fixtures used in our daily life.
A primary object of the present invention is to provide an LED light holder assembly for easily mounting and removing an LED light to and from lighting fixtures.
Another object of the present invention is to provide an LED light holder assembly that allows an LED light mounted thereon to be easily adjusted to different light projecting directions.
A further object of the present invention is to provide an LED light holder assembly that could be easily assembled and disassembled to facilitate installation and maintenance thereof.
To achieve the above and other objects, the LED light holder assembly of the present invention includes an LED light holder and two elastic terminals serving as two power outputs. The light holder has two curve-profiled terminals fixedly provided at two opposite sides of the light holder. Each of the two elastic terminals is connected at an end to a circuit board, and has a free end formed into an annular contact for press contacting with the curve-profiled terminals. When the light holder is positioned between the two elastic terminals, the curve-profiled terminals on the light holder are in press contact with and electrically connected to the annular free ends of the elastic terminals.
In the LED light holder assembly of the present invention, the curve-profiled terminals on the LED light holder are partially protruded through the annular contacts at the free ends of the two elastic terminals, so that the annular contacts of the elastic terminals also serve to support the LED light holder thereon.
In the LED light holder assembly of the present invention, when the LED light holder is mounted between the two elastic terminals, it can be conveniently turned to regulate the light projecting direction of the LED light mounted thereon.
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein
Please refer to
The LED light 11 is provided at a top with two pins 13 to serve as power inputs. The two spherical terminals 12 on the LED light holder 10 are separately welded to the two pins 13. With the above arrangements, the LED light holder 10 could be rotated between the two elastic terminals 20 to regulate the light projecting direction of the LED light 11.
Before the LED light holder 10 is positioned between the two cups 23, a distance between the two annular rims 24 of the cups 23 connected to the free ends 22 of the two elastic terminals 20 is slightly smaller than a diameter of the spherical LED light holder 10. When the LED light holder 10 is positioned between the two cups 23, the annular rims 24 of the two elastic terminals 20 are forced apart to thereby produce an elastic restoring force to firmly clamp the LED light holder 10 therebetween.
The LED light holder assembly of the present invention can be more easily installed and replaced, and allows regulation of the light projecting direction of the LED light mounted on the LED light holder, and is therefore very practical for use on daily lighting fixtures.
