Abstract
A lamp holder, particularly a lamp holder that contains a sensing control. A
pulling chain is connected to the sensing control, so the chain serves a touch-control purpose. A user can activate the sensing control to switch the lamp on or off merely by lightly tapping, touching or feeling the chain by hand.
Meanwhile, the sensing control is capable of multiple-step lighting control of the lamp. By wired or radio transmission, the lamp holder is capable of close or remote control, thereby replacing mechanical control in conventional models with electronic control, and bringing better convenience to the user.

Description
Lamp Holder BACKGROUND OF THE LNVENTION
(a) Field of the invention The present invention relates to a lamp holder that has an electronic sensor installed inside, and a pulling chain connected to the sensor, thereby enabling a function of sensing control to the chain.
(b) Description of the Prior Art FIGS. 1 and 2 illustrate a prior art of pulling-switch type lamp holder, comprising a base l, a support rod 11 erected at the center of the base 1, the upper end of the support rod 11 connected to a lower part of a socket shell 21, a mechanical hand-pull switch 3 installed inside the socket shell 21, the pulling switch 3 having a chain 31 that runs out of a channel 24 through a hole on one side of the socket shell 21. On the outside of the upper end of the socket shell 21 is a thread part 211. At the lower end of a lamp socket 22 is an insert part that is inserted into the socket shell 21. Near the middle of the lamp socket 22 is a protrusion part 222. At an upper part of a lock unit 23 is a flange part 231 with a smaller inside diameter. Inside the lock unit 23 is a thread part 232. The lock unit 23 is mounted onto the lamp socket 22. The insert part 221 of the lamp socket 22 is inserted into an upper end of the socket shell 21. By screwing the lock unit 23 to the upper end of the socket shell 21, the lamp socket 22 is joined and fastened to the socket shell 21. Finally, a lamp bulb 4 is inserted in the lamp socket 22..
Therefore, a power cord 5 is inserted through the bottom of the base 1 into the support rod 11 and into the socket shell 21, with one terminal wire 51 of the power cord 5 connected to a contact point of the pulling switch 3 that is installed inside. Meanwhile, another terminal 52 of the power cord 5 is connected to a contact point of the lamp socket 22. A conductive wire 6 is connected to somewhere between the pulling switch 3 and another contact point of the lamp socket 22. So, when a user pulls chain 31 repeatedly, the pulling switch 3 produces a continuous cycle of multiple steps of switching on and off of operations, to achieve control of multiple steps of lighting to the lamp bulb 4 on lamp socket 22.
The aforementioned conventional construction of pull-string control of lamp holder to switch on and off a lamp has been known to most consumers in past years. But the conventional, mechanical pulling control of lamp holder involves some shortcomings that need improvement. Such as:
1. Switching on and off of the lamp by pulling a string by hand is a simple operation, but it is also time-consuming and labor consuming. Extended use or excessive pulling force may result in damage to the pulling switch 3, and shortened service life of pulling switch 3.

1. Switching on and off of the lamp by pulling a string by hand is a simple operation, but it is also time-consuming and labor consuming. Extended use or excessive pulling force may result in damage to the pulling switch 3, and shortened service life of pulling switch 3.
2. Once the pulling switch is damaged, the lamp will not work at all. Besides, extended use of the mechanical pulling switch could easily result in rusting on its contact points and subsequent failure.
SUMMARY OF THE INVENTION
To overcome the aforementioned shortcomings of conventional pull-string type of lamp holder, the present invention introduces a sensing control inside the lamp holder, with a pulling chain connected to the sensing control, so the entire chain is capable of producing touch-control sensing effects. By lightly patting, touching or feeling the chain by hand, the user can switch on or off the lamp by simplified control.
The aforementioned chain is optionally replaced by a conductive string that has the same sensing function.
Moreover, the sensing control is capable of multiple steps of control to obtain different degrees of lighting.
Furthermore, signals produced when the chain is touched or felt by an object can be transmitted to a nearby or remote lamp or electrical appliance by radio transmission.
Other objectives of the present invention and a scope of further applications can be understood from the following detailed description. It is to be understood, however, that such detailed description of preferred embodiment shall not be based to limit or restrict the present invention.

FIG. 3 is a section view of an embodiment of the present invention.
FIG. 4 is a section view of another embodiment of the present invention.
DETAILED DES(.'RIPTION OF PREFERRED EMBODIMENTS
Please refer to FIG. 3. The present invention of lamp holder comprises a base 1, a support rod 11 erected on the center of the base 1 and connected to a socket shell 21, a lock unit 23 joining the lamp socket 22 with the socket shell 21, an electronic sensing control 7 installed inside the socket shell 2I, and a hand chain 31 connected to the sensing control 7 and running out of one side of the socket shell 21 through a channel 24.
A power cord 5 is directly connected to the sensing control 7. A control cord _3_ 8 of a lamp bulb 4 to be controlled is connected to the lamp socket 22. The chain 31 is also connected to the sensing control 7 to serve as a contact point. So when a user lightly pats, touches or feels chain 31 by hand, the sensing control 7 will switch the lamp on or off. The present invention is equipped with the following characteristics:
1. The lamp is easily controlled by lightly patting, touching or feeling the chain 31. The operation is time saving, labor saving and quite convenient.
2. Its service life can be extended significantly because the control mechanism does not consist of a mechanical switch.
As shown in FIG. 4, the hand-pull type of chain 31 is optionally replaced by a conductive string 32. Because of its conductivity, the conductive string 32 has a sensing function.
Effects of sensing control of the chain 31 or the conductive string 32 can also be changed by changing the frequency of the user's manual touch or feeling on the chain 31 or the conductive string 32. For example, when the control chain or the conductive string 32 is touched or felt the first time, a first step of lighting control is activated; when the control chain 31 or the conductive string 32 is touched or felt the second time, a second step of lighting control is activated; and then, when the control chain 31 or the conductive string 32 is touched or felt the third time, the lamp will go off. Thereby, the present invention is capable of achieving the same effects of multiple-step control, just like a conventional pull-string switch. Importantly, applications of the present invention also include, but are not limited to, other electrical appliances controlled by the chain 3I, such as the fluorescent lamp on the ceiling, art lamps, and many other types of lamps.
Moreover, signals created by touching or feeling the chain 31 or conductive string 32 are optionally transmitted to a nearby or remote lamp or electrical appliance by radio transmission.
Summing up, the present invention adopts a pulling chain switch as a sensing control, with improvement on various operational inconveniences and limitations as can be found in the conventional, mechanical switch. The present invention enables control by mere touch or feel, which cannot be found in conventional pull-string switches.
