1. Field of the Invention
This invention relates to a non-contact and non-disposable electric induction LED lamp.
2. Description of the Prior Art
The inventor of this invention previously devised various kinds of non-disposable LED lamps for improving the drawbacks of a conventional LED lamp that a whole set of the conventional LED lamp must be eliminated and replaced with a new one so long as a certain component of the LED lamp is damaged. An electric bulb-shaped non-disposable LED lamp, as shown in
Although foresaid non-disposable LED lamps are widely known and greatly loved by consumers after being launched to the markets, yet the inventor of this invention found that since the power module 2 is to have electricity transmitted to the luminous module 4 via the this first connector 3 and the second connector 5 that are combined together; therefore, water vapor and dust are apt to get into the power module 2 along the first connector 3 and also into the luminous module 4 along the second connector 5, thus shortening service life of both the power module 2 and luminous module 4. In addition, to replace the base 1 or the luminous module 4 and recombine them together, a user has to make the first connector 3 aligned to the second connector 5, resulting in much inconvenience. Therefore, finding the defects of foresaid non-disposable LED lamp and adhering to the spirit of endeavoring to do everything better, the inventor of this invention think that it is really necessary to ameliorate the conventional non-disposable LED lamp.
The objective of this invention is to offer a non-contact and non-disposable electric induction LED lamp, able to have the electricity of a power source transmitted to a luminous-radiating unit in a non-contact mode to enable an LED module of the luminous-radiating unit to emit light.
The non-contact and non-disposable electric induction LED lamp in the present invention includes a power source and a luminous-radiating unit. The power source is formed with a power source module electrically connected with a first electric induction plate. The luminous-radiating unit to be combined and fixed together with the power source is provided with a second electric induction plate corresponding with the first electric induction plate and electrically connected with an LED module.
The non-contact and non-disposable electric induction LED lamp of this invention is to have the electricity of the power source transmitted to the luminous-radiating unit via electromagnetic induction produced between the first and the second electric induction plates, that is, transmission of electricity is carried out in a non-contact mode. Therefore, no outer metallic contact needs to be provided and hence, the power source and the luminous-radiating unit can be sealed completely, attaining waterproof and dustproof effects, facilitating the LED lamp to be partially replaced and reducing electronic waste.
This invention will be better understood by referring to the accompanying drawings, wherein:
A non-contact and non-disposable electric induction LED lamp 100 in the present invention can be bulb-shaped, disk lamp-shaped or fluorescent lamp-shaped. A first preferred embodiment of a bulb-shaped non-contact and non-disposable electric induction LED lamp 100 in the present invention, as shown in
The power source portion 10 is formed with a base 11 and provided with a first combination member 12, which is an engage groove in this preferred embodiment. The base 11 has one side provided with an E27 electric adapter 13, and a power source module 14 electrically connected with the electric adapter 13 is installed on the base 11. The base 11 has another side set with a first electric induction plate 15 received therein with a first induction coil 16 and electrically connected with the power source module 14.
The luminous-radiating unit 20 is disposed with a heat-dissipating body 21 composed of multilayer circular radiating fins, and provided with a second combination portion 22 to be combined with the first combination portion 12 to assemble and fix the luminous-radiating portion 20 together with the power source 10. In this preferred embodiment, the second combination portion 22 is an engage projection so that the luminous-radiating unit 20 can be firmly fixed with the power source 10 in a mode of mutual engagement. Further, the heat-dissipating body 21 has one side that faces the base 1 provided with a second electric induction plate 23 having a second induction coil 24 installed therein, letting the second electric induction plate 23 of the luminous-radiating unit 20 correspond with the first electric induction plate 15 of the power source 10. An LED module 25 is mounted on the luminous-radiating unit 20 and electrically connected with the second electric induction plate 23, and the luminous-radiating unit 20 is further provided with a lamp shade 26 to be covered at the outer side of the LED module 25.
In using, referring to
Moreover, since the electricity of the power source 10 is transmitted to the luminous-radiating unit 20 in a non-contact mode; therefore, the luminous-radiating unit 20 can be replaced with a luminous-radiating unit of different specifications according to needs in use. For instance, a daylight-colored luminous-radiating unit 20 can be replaced with an electric bulb-colored luminous-radiating unit 20.
A second and a third preferred embodiments of a non-contact and non-disposable electric induction LED lamp 100, as shown in
While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
