1. Field of the Invention
The present invention relates to an improvement in the construction of a lamp holder, particular to an improved lamp holder, in which different lighting can be displayed no matter a lamp base is fastened or apart from the lamp holder by providing extension arms that can carry the function element with contact points in different heights in the bottom of said lamp base.
2. Description of the Prior Art
As generally known, series lamp strings are frequently used in festivities or decorations; particularly the Christmas lamps are widely used in Christmas seasons. However, light bulbs of conventional series lamp strings may come off due to shock or collision. In addition, the light bulbs will not work when the tungsten filaments of the bulbs are burned-out after a period of usage. It is troublesome to merely replace the bulb or lamp holder, while it costs much to replace the whole lamp string.
In order to overcome the above-mentioned shortcomings, U.S. Pat. No. 6,283,797 has proposed to provide a resistor in the lamp holder, in which when one bulb in series lamp strings are burned out, the resistor can act as a route so that other bulbs of series lamp strings can still work.
Accordingly, the present invention has been invented to solve the above-mentioned problems occurred in the prior art.
An objective of the present invention is to provide a lamp holder device having a function element, in which a downward extending extension arm having the clip-on capability is provided in the bottom of said lamp base, and a function element having different function properties in accordance with displacement of the function element is provided in said extension arm, which enables different lighting display when the lamp base and lamp holder are fastened or apart from each other.
The lamp holder device having a function element in the present invention comprises: a lamp base, a light emitting element, a set of conducting slices, a function element, a lamp holder, and a set of electrical wire. Said light emitting element is provided in the lamp base, where extension arms in the bottom of said lamp base have side holes for the side of the function element held within can be outwardly protruded. When the entire components are assembled, an electric circuit is formed, while the light emitting element and function element can function as default. When said lamp base including light emitting element is connected to the lamp holder and displaced or apart from each other, said function element is also displaced. The conducting contact point of said function element and the conducting slices in the lamp holder are contacted in different places or different ways, which enables said function element to function as default after its displacement.
In the lamp holder device having a function element in the present invention, the function element being used may be single or multiple sets of resistors, PPTC (Polymeric Positive Temperature Coefficient Resistor), or fuses. The fuses being used may be resettable fuse, alarm fuse or temperature transmitting fuse.
In the lamp holder device having a function element in the present invention, at least a flange is provided on the conducting slices in the lamp holder, providing the function element with the conductivity. By allowing the side of said function element to have contact points in different heights, the light emitting element in the lamp base will not be turned off because the lamp base and lamp holder are loosen and apart from each other. On the contrary, said function element has different contact point with the conducting slices because the position of said lamp base relative to the lamp holder is changed, which changes the lighting display of said light emitting element, and serves as another purpose of the present invention.
In the lamp holder device having a function element according to the present invention, the function element can be contacted with the conducting slices in different places because said function element has several contact points in different heights, which allows the light emitting element to maintain bright state. When this is used in the series lamp string, the whole lamp string will not be off due to the loose of lamp base and being apart from the lamp string (this may impact the festivals or decoration atmosphere), which serves as another purpose of the present invention.
The detailed structure, application principle, purposes and functions of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings.

The lamp holder device having a function element in the present invention, as shown in
A neck flange 12, which allows to properly cover the fringe of lamp holder 6 when it is assembled with the lamp holder 6; two downward extending extension arms 13 and 14 are provided in the bottom of said lamp base 1, and an accommodation space is provided properly between the two extension arms 13 and 14, in which the interior wall is provided with inward protruding flat-top 131 and 141. The two sides of said extension arms 13 and 14 are not completely contacted with each other, and thus a proper interval is formed having a rectangular hole or a downward penetrating channel 132 and 142. The present embodiment uses the downward penetrating channel as an example.
Said light emitting element 2 may be a LED lamp or a tungsten lamp. The present embodiment uses a lamp bulb as an example. The center of light emitting element 2 is provided with downward extending filaments 21 and 22. When light emitting element 2 is inserted into the lamp base 1, said filaments 21 and 22 are diverged outward due to the contact with the crotched part 10 in the lamp base, and passed out of the channels 132 and 142 between two extension arms 13 and 14. When the lamp base 1 is being inserted into the lamp holder 6, the filaments 21 and 22 are formed and extended downward to flip to outside the lamp base. Then, the filaments are contacted and conducted with conducting slices 4 and 5 in the lamp holder 6.
Said function element 3, provided between two extension arms 13 and 14 in the bottom of the lamp base, can be clipped and held stably on the flat-top 131 and 141 of said extension arms 13 and 14. A plurality of electrical devices with control functions in the interior of said function element 3 provide conductivity by using the outward extending contact points on its side in the same height. In the present embodiment, the sides of said function element 3 have two sets of first contact point 31 and second contact point 32 in different heights. The preset function of first contact point 31 and second contact point 32 may be different or the same. When said function element 3 is provided between the extension arms 13 and 14 in the bottom of the lamp base, the first contact point 31 and second contact point 32 on the two sides are located on the channel 131 and 141 of extension arms 13 and 14, so that the contact points can be contacted externally. Moreover, a protruding insert pointer 33 is provided in one direction of said function element 3, by which the function element can be inserted correctly, and thus the damage of lamp strings caused by improper installation can be avoided.
Said conducting slices 4 and 5 provided in the lamp holder 6 mainly provide with contact and conductivity for the light emitting element 2 and function element 3. The upper parts 41 and 51 of said conducting slices 4 and 5 are formed as slice-shaped and attached to the interior wall of said lamp holder 6. Two inward protruding flanges 42 and 52 are formed on the surface of said lamp holder 6. The electrical wires 7 and 8 are connected to the lower ends of said lamp holder 6, and said electrical wires 7 and 8 are connected to power or lamp holder of other series lamp strings.
Said function element 3 may be single or multiple sets of resistance, or single or multiple sets of PPTC (Polymeric Positive Temperature Coefficient Resistor). Said function element 3 may be signal or multiple sets of fuses. The fuses may be resettable fuse, alarm fuse or temperature transmitting fuse.
When the whole components have been assembled, as shown in the figure, besides filaments 21 and 22 of said light emitting element 2 and slice-shaped upper part 41 and 51 of conducting slices 4 and 5 are contacted and conducted, the first contact point 31 and second contact point 32 of said function element 3, which is clipped and held by the extension arms 13 and 14 of said lamp base 1, are contacted with the flanges 42 and 52 of conducting slices 4 and 5 respectively. As such, through the preset function of said function element 3, the light emitting element 2 generates lighting changes before the lamp base 1 is not apart from the lamp holder 6.
When the lamp base 1 is apart from lamp holder 6 due to external force (i.e. man-made or natural factor, such as wind power), as shown in
Accordingly, during implementation, besides the filaments 21 and 22 of light emitting element 2 have been contacted and conducted with the slice-shaped upper part 41 and 51 of said conducting slices 4 and 5, said function element 9 being suppressed by the extension arms 13 and 14 of said lamp base 1 are not contacted with the flanges 42 and 52 of said conducting slices 4 and 5.
When lamp base 1 is apart from the lamp holder 6 due to external force (i.e. man-made or natural factor, such as wind power), the function element 9 that has originally suppressed by the extension arms 13 and 14, due to lose of suppressing force, restores the elasticity by means of the elasticity element 92, and moves said function element 9 upward, so that the conducting materials 91 provided in the exterior of said function element 9 contact with the flanges 42 and 52 of conducting slices 4 and 5 due to the upward movement. Accordingly, the interior of said lamp holder remains as the route, so that the power of series lamp strings will not be cut off.

A signal receiving and delivering mechanism 84, which is used for connecting power and the IC chip 81 and its assisted parts assembly 82 and uses the wireless signal of infrared rays (IR) or microwave radio frequencies (RF); the signal receiver mechanism 841 and receiver 72 are integrated as a unity. In consideration of practical utility, the IC chip 81 is provided with the preset On/Of or reset function to switch to On/Off automatically or reset. The entire components are then connected with electrical wires 85 to form an integral whole.
Multiple sets of lamps can be connected in series during usage by using the power connector to connect to power. IC chip and its assisted parts assembly can be used to drive multiple sets of lamps, so that the light emitting device can generate light or shade. Then, any of the IC chips can be used to generate signals that are transmitted to each set of IC chip, while activating (START) or resetting (RESET) each string of lamp sets, controlling to have the same preset electrical functions, and generating the effect of synchronously operating multiple strings of lamp sets.
As understood from the above descriptions, the lamp holder device having a function element according to the present invention allows bulbs in the series lamp string to be bright even when one or more bulbs or lamp holder are apart, which overcomes the shortcoming occurred in the conventional series lamp string that the whole lamp string may be off when a bulb is burned out or a lamp holder is apart. Also, the present invention has not yet been made public, which is consistent with relevant Patent Law.
Although a preferred embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
