Description

FIELD OF THE INVENTION

The present invention relates to LED lighting modules, and more particularly, to a power device adapted for use with an LED lighting module and installed directly on a fluorescent lamp holder, such that a power controller of the power device can be changed independently.

BACKGROUND OF THE INVENTION

Conventional lighting equipment mainly includes incandescent lamps and fluorescent tubes. However, incandescent lamps and fluorescent tubes have their own disadvantages, such as high power consumption and short service life. By contrast, nowadays, high-power light-emitting diodes (LED) have advantages, namely low power consumption, high durability, and long service life, and thus are good candidate for replacing the conventional incandescent lamps gradually. Nonetheless, existing light-emitting diodes (LED) are confronted with plenty of technical problems, one of which is about enabling a user to change an LED lamp or an LED bulb directly without the hassles of changing an LED lamp/bulb holder.
To develop a substitute for conventional fluorescent tubes, the prior art did put forth some solutions. Referring to FIG. 1, a conventional LED lamp 10 has one end coupled to a power supplying device 20. The power supplying device 20 comprises therein electronic components, such as a circuit board and a driving control IC. The LED lamp 10 has the other end coupled to a conductive terminal 30. The outer end of the power supplying device 20 is coupled to another conductive terminal 30. Both the LED lamp 10 and the power supplying device 20 together are installed on a lamp holder. The power supplying device 20 converts alternating current (AC) into direct current (DC), and rectifies the direct current (DC) to provide voltage and current required for the LED lamp 10. However, with the power supplying device 20 being directly integrated with the LED lamp 10 to form a unitary structure, if any of the electronic components inside the power supplying device 20 gets damaged or malfunctions, it will be necessary to change the LED lamp 10 and the power supplying device 20 together to the detriment of cost effectiveness.
Referring to FIG. 2 and FIG. 3, to cope with the aforesaid problem and drawback of the power supplying device 20, the prior art put forth another solution that involves designing power supplying devices 20a, 20b and the LED lamp 10 in a manner to have separable structures, and connecting the LED lamp 10 to the power supplying devices 20a, 20b by a thread connection structure 201a and a conductive pin 201b, respectively, such that it will be necessary to change the power supplying devices 20a, 20b only when the power supplying devices 20a, 20b get damaged or malfunction. Nonetheless, the power supplying devices 20a, 20b contain multiple electronic components, among which is a power controller (an electric transducer) that is most likely to get damaged or malfunction. It is not cost-effective to the power supplying devices 20a, 20b just because the power controller gets damaged or malfunctions. Due to the aforesaid structural design, to change the power supplying devices 20a, 20b, it is necessary to remove both the LED lamp 10 and the power supplying devices 20a, 20b from the lamp holder and then mount the old LED lamp 10 and new power supplying devices 20a, 20b on the lamp holder to the detriment of user convenience.
Accordingly, it is imperative to provide a power device adapted for use with an LED lighting module and characterized by ease of replacement of a power controller and a low cost of changing the power controller.

SUMMARY OF THE INVENTION

In view of the aforesaid drawbacks of the prior art, the inventor of the present invention conceived room for improvement in the prior art and thus conducted extensive researches and experiments according to the inventor's years of experience in the related industry, and finally developed a power device of an LED lighting module such that a power controller thereof can be changed easily and at a low cost.

In the first preferred embodiment, the power device is characterized in that: the casing of the power device has a guide slot; and the power device further comprises a power controller corresponding in position to the guide slot and insertable thereinto for controlling power supplied to the LED lighting module.
In the first preferred embodiment, the power controller comprises a plate having an end provided with a plurality of guide terminals for electrical connection with the power device, and the plate has therein at least an LED driving control IC.
In the first preferred embodiment, the light-penetrable lamp of the LED lighting module is a slender lamp installed on a fluorescent lamp holder, and the casing of the power device is connected to the slender lamp.
In order to achieve the above and other objectives, the present invention provides an power device of an LED lighting module, wherein, in the second preferred embodiment, the LED lighting module comprises a light-penetrable lamp having therein an LED lighting component, and the power device is disposed inside the light-penetrable lamp. In the second preferred embodiment, the power device is characterized in that: the light-penetrable lamp has a guide slot in communication with the power device, and the power device further comprises a power controller corresponding in position to the guide slot and insertable thereinto for controlling power supplied to the LED lighting module.
In the second preferred embodiment, the light-penetrable lamp of the LED lighting module is a slender lamp installed on a fluorescent lamp holder, and the power device has a casing disposed inside the slender lamp.
Accordingly, a power device of an LED lighting module according to the present invention is characterized in that a power controller thereof is implemented in the form of a self-contained element that is easily and quickly inserted into a guide slot of a light-penetrable lamp or the power device rather than directly fixedly connected to the power device. Hence, if the power controller gets damaged, malfunctions, or undergoes alteration of its specifications and thus needs to be changed, it will not be necessary to change the power device in whole, nor will it be necessary to remove the LED lighting module in order to change the power controller. Hence, the power device of the present invention overcomes the drawbacks of a conventional LED lamp, renders it easy to change the power controller, and cuts replacement costs.
