Abstract
The utility model discloses an LED light bulb, comprising a hollow base and a hollow lampshade, wherein, the bottom and the periphery of the base are respectively provided with an electrode, the lampshade is connected with the top of the base, the base is inside provided with a power converter connected with the electrode, and the lampshade is inside provided with at least one LED connected with the power converter. The LED has the advantages of lower electric power consumption and longer service life over a tungsten lamp, therefore, the LED gradually replaces the tungsten lamp. The utility model makes use of the advantages of the LED and is capable of converting the AC of commercial power into DC needed by LED through the power converter, which leads to the LED applicable to the lamp holder originally for the tungsten lamp. Therefore, the utility model is convenient and practical.
Description
Technical field
The utility model relates to a kind of bulb, especially a kind of light emitting diode bulb that is provided with light-emitting diode chip for backlight unit in lampshade.
Background technology
General existing bulb is based on osram lamp, it is provided with tungsten filament and inert gas environment in lampshade, electric current by tungsten filament to heat this tungsten filament to temperature up to 2500 ℃, so that heat radiation produces luminous energy, yet this osram lamp has only 5% electric energy to be convertible into luminous energy approximately, and all the other all are converted to heat energy, therefore osram lamp is wasted a large amount of electric energy, but luminosity still can't improve.In addition, the life-span of osram lamp is short, is not durable very much.
The utility model content
Applicant of the present utility model is because existing osram lamp power consumption, luminosity is low and the life-span is short, therefore through constantly attempting and effort, creates this light emitting diode bulb finally.
The purpose of this utility model provides a kind of light-emitting diode chip for backlight unit that is provided with in lampshade, increasing bulb brightness under the situation of low power consumption, and have the light emitting diode bulb in extremely long service life.
For achieving the above object, light emitting diode bulb of the present utility model, it comprises a hollow base and a hollow lampshade, and this base bottom and outside respectively are an electrode, and this lampshade is connected in the pedestal top, it is characterized in that:
Be provided with the power supply changeover device that connects electrode in this pedestal, be provided with at least one light emitting diode that is connected in this power supply changeover device in this lampshade.
Because light emitting diode has power consumption and the extremely long service life (about five ten thousand to ten ten thousand hour) low than osram lamp, therefore replace osram lamp gradually, and the power consumption of light emitting diode is the highest only has to 2.5 watts (W), very power saving, so the utility model has utilized the advantage of light emitting diode, and can also convert the alternating current of civil power to light emitting diode required direct current by power supply changeover device, it can be useful in originally accept on the lamp socket of osram lamp, very convenient and practical.

The specific embodiment
Please referring to Figure 1 and Figure 2, light emitting diode bulb of the present utility model, its spiral shell is located at a tool internal thread and is had in the lamp socket (not shown) of the plug that can be connected with supply socket, this light emitting diode bulb comprises a hollow base 11 and a hollow lampshade 12, the bottom of this pedestal 11 and outside respectively are provided with an electrode, and this outside is provided with corresponding to the internal thread of lamp socket and this light emitting diode bulb can be fixed at the external screw thread 111 of lamp socket, this lampshade 12 is connected in pedestal 11 tops, it is characterized in that:
Be provided with the power supply changeover device 20 that connects electrode in this pedestal 11, be provided with in this lampshade 12 and be connected in this power supply changeover device 20 and inner at least one light emitting diode 30 with chip (not shown).
Among the embodiment of the present utility model, be that the mode that two light emitting diodes 30 pile up with vertical type is arranged in the lampshade 12, and respectively be connected that the mode that plural light emitting diode 30 all piles up with this vertical type places in the lampshade 12 with power supply changeover device 20.
Please referring to Fig. 2 and shown in Figure 3, this power supply changeover device 20 comprises filter circuit 21 and bridge rectifier 22 and at least one resistance 23 that connects two electrodes respectively, this bridge rectifier 22 is connected with electrode (being power supply) by filter circuit 21, bridge rectifier 22 outputs are connected with light emitting diode 30 by resistance 23 again, thereby make and to send into alternating current in the light emitting diode bulb by the power supply that plug connected of lamp socket, can convert the required dc supply of light emitting diode 30 to by this power supply changeover device 20, produce luminous energy with the chips that drive in the light emitting diode 30.
Because light emitting diode 30 has power consumption and the long service life (about five ten thousand to ten ten thousand hour) low than osram lamp, therefore can replace osram lamp gradually, so the utility model has utilized the advantage of light emitting diode 30, and can also it is applicable to by power supply changeover device 20 originally to accept on the lamp socket of osram lamp, very convenient and practical.
