2. Description of the Related Art
In the present day, light-emitting diodes (LEDs) remain common and widely-used electronic components. With merits such as small size, quick response, long service life, low power consumption and low thermal generation, they hold recognition as one of the most popular components used in electronic products. Accordingly, in recent years, as LED lamps become excellent substitutes for conventional incandescent lamps or fluorescent lamps, various LED lamps continue to be developed.
Currently available LED lamp bodies usually simultaneously function as a thermal dissipator and a chamber for accommodating a power converter. Thermal energy generated by the LED and the power converter can be conducted to the outside of the LED lamp's body by way of the thermal dissipator. Although the aforementioned structure is helpful for thermal dissipation and insulation, the thermal dissipation ability of the thermal dissipator is severely limited due to its insufficient surface area. Accordingly, the structure is not applicable to a LED lamp with higher power. Besides, the structure needs a lot of space to accommodate the thermal dissipator and the power converter, which leads to the relatively large size of the LED lamp. Furthermore, as a large amount of thermal heat is generated when the LED is working and the power converter is disposed in the accommodating space for dissipating the thermal energy generated by the LED, electronic components installed at the power converter are apt to be damaged due to overheating, which can reduce the LED lamp's service life. Thus, it has become an urgent issue to develop a LED lamp which has small size, great thermal dissipation ability, modularized components and is applicable to LED lamps with high power.
Therefore, it is one of the primary objectives of the present invention to provide a power converter contained base, a lamp with a power converter contained base and a lamp with a separable power converter contained base to resolve the problems in conventional lamps or bases, such as large size and poor thermal dissipation.

The detailed structure, operating principle and effects of the present invention will now be described in more details hereinafter with reference to the accompanying drawings that show various embodiments of the invention as follows.
The detailed description of the present invention will be discussed in the following embodiments, which are not intended to limit the scope of the present invention, but can be adapted for other applications. While drawings are illustrated in details, it is appreciated that the quantity of the disclosed components may be greater or less than that disclosed, except expressly restricting the amount of the components. Although specific embodiments have been illustrated and described, it will be appreciated by those skilled in the art that various modifications may be made without departing from the scope of the present invention, which is intended to be limited solely by the appended claims.
Referring more particularly to the drawings,
The first commercial standard base 110 described in the application may be E26, E27 or other commercial standard base and thereby the power converter contained base may be fixed to and electrically connected to the commercial standard socket in order to be powered by external AC or DC power source.
The fundament 120 of the present invention functions as a connector for connecting the light-emitting member with the thermal dissipater, and the cover 130 is combined with the fundament 120 and the first commercial standard base 110 to define an accommodating space 170 to achieve thermal insulation and dustproof. Apparently, the fundament 120 and the cover 130 may be further minified or integrally formed, such that the accommodating space 170 may be the internal space inside the first commercial standard base 110.
As shown in
The power converter according to the present invention is used to convert the external AC or DC power source into the power source that the light-emitting member needs. Accordingly, the components inside the power converter contained base should be able to achieve electrical connection. For example, electrical connection may be achieved through the first commercial standard base 110, the power converter 140, the cover 130 and the first connector 150. Those skilled in the art would easily understand that the first commercial standard base 110 and the power converter 140 may be selectively electrically connected to one, two or three of the fundament 120, the cover 130 and the first connector 150 to achieve electrical connection.
In some preferred embodiments, the accommodating space may further comprise thermal conducting material. Accordingly, thermal generated by the power converter 140 may be conducted to the first commercial standard base 110 by the thermal conducting material to enhance the thermal dissipation and then render the power converter 140 more stable.
The first connector 150 is mainly used in connection. For example, the first connector 150 may be a hook, a notch, male thread or female thread to be engaged with or fastened to the connector of the light-emitting member. In some preferred embodiments, the first connector 150 may also be used to electrically connect the power converter 140 with the light-emitting member. The first connector 150 may comprise a conductive metal bar, a metal shrapnel or the like, or a commercial standard connector for electrical connection. For example, the first connector 150 may be a GU type base or socket, which may comprise but not be limited to GU5.3, GU10, GU24 and B22D type base or socket to be connected to a matched socket or base so as to achieve fixation and electrical connection. However, the commercial standard connector may tend to be accidentally connected to the different product with the same base and socket by a user. Accordingly, the power converter contained base 100 may further comprise various types of fool-proof apparatuses (such a protrusion) to prevent the damage resulting from user's misuse.
It is worthy to point out that the power converter of the power converter contained base according to the present invention is disposed in the space defined by the cover, the fundament and the first commercial standard base. Accordingly, when the power converter is working, the electromagnetic radiation generated by the power converter can be blocked by the base's metal housing, which can effectively reduce the electromagnetic radiation generated by the power converter. In addition, thermal generated by the power converter can be conducted to the outside of the base via the thermal conducting material, the base, the socket to which the base is connected and corresponding conducting wires. Moreover, the components of the base and the socket may be further made of metal, ceramics, thermally conductive plastics and the like to effectively improve the thermal dissipation of the power converter and thereby render the power converter more stable.
In some preferred embodiments, the surface of the power converter contained base, such as the surface of the cover 120 or the base 130, may comprise a power adjustment component. The component may be a cross knob, a pointer type knob or a protruded knob for a user to adjust the output of the power converter by a screwdriver or his own hand. The component may just be a hole on the cover 120 or the base 130 for a screwdriver and the like to be put into to adjust the output of the power converter.
Installed on the power converter contained base according to the present invention may be a LED light source, an OLED light source or any light source needing to be powered by the power converter which performs power transformation on an external AC or DC power source.
As described above, the first connector 150 may be disposed at the cover 130 or the fundament 120, and the power converter contained base 100 may be connected to the second connector 250 of the light-emitting member 200 through the first connector 150, wherein the first connector 150 and the second connector 250 may be a set of hook and notch or a set of male thread and female thread, a set of second commercial standard base or the like. Similarly, in the preferred embodiment, the GU type socket is just taken as an example for illustrating the first connector 150. The first connector 150 may be other commercial standard sockets, such as B22D and the like, or various electrical connection bases or sockets. Apparently, these electrical connection bases and sockets may be just used in fixation and connection instead of electrical connection. The aforementioned are just some preferred embodiments, and those skilled in the art would easily understand that the first connector and the second connector may comprise more embodiments, which should be in a range limited by the specification of the present invention.
The light-emitting member 200 may comprise a second connector 250 corresponding to the first connector 150. The first connector 150 may be connected to the second connector 250 to make the first commercial standard base 110, the power converter 140, the one of or the combination of two or three of, the fundament 120, the cover 130 and the first connector 150, and the light-emitting member 200 become electrically connected. As described above, the fundament 120 and the cover 130 may be further disposed with a power adjustment component electrically connected to the power converter 140 in order to directly or indirectly adjust the output of the power converter 140.
It would be easily understandable that the first connector 150 and the second connector 250 may be made of material with low thermal conductivity to almost completely or completely prevent thermal from being conducted to the power converter contained base.
It is worthy to point out that the special design of the present invention makes it possible for each of the components of the lamp with power converter contained base according to the present invention to be separately modularized and manufactured. Accordingly, the present invention is more convenient and of higher commercial value than the prior art. Besides, the present invention may further comprise a power adjustment component disposed at the cover or the fundament, which makes it possible for the power converter contained base to be connected to various light-emitting members with different power. Thus, the present invention is more flexible in use than the prior art.

In the embodiment, the first connector 150 may comprise male thread and the second connector may comprise female thread which can be fastened to the male thread. Similarly, the first connector 150 and the second connector 250 may be a set of hook and notch or the like. In the embodiment, the cover 130 does not contact the light-emitting member 200, and a space is left between them, which is different from the aforementioned embodiments. As air can pass through the space, the space is helpful to thermal dissipation and thermal insulation. Accordingly, the space can almost entirely or entirely block thermal generated by the light-emitting member 200 from the power converter contained base 100.
The cover 130 can be, no matter the cover 130 contacts the light-emitting member 200 or not, electrically connected to the light-emitting member 200 via the second connector 250 with electrical conductivity after the first connector 150 is connected to the second connector 250. In some preferred embodiments, the first connector 150 and the second connector 250 are just used in fixation and connection, and the cover 130 may be electrically connected to the light-emitting member 200 via extra electric wires, fool-proof device or the like.
Besides, the second connector 250 may be disposed at a thermal dissipater (not shown), and the light-emitting member 200 may be also disposed at the thermal dissipater. Therefore, the power converter contained base 100 may be connected to the second connector 250 through the first connector 150 in order to be electrically connected to the light-emitting member 200 through the first connector 150 and the thermal dissipater. Thermal generated by the light-emitting member 200 may be dissipated by the thermal dissipator, which can enhance the thermal dissipation of the apparatus and block the thermal generated by the light-emitting member 200 from the power converter 140.
