Description

The LED bulb

Technical field

The utility model relates to a kind of lighting apparatus, relates in particular to a kind of LED bulb that is used to replace the conventional incandescent use.

Background technology

Though incandescent lamp is used less at present, but up to this point people's lamp socket of still being extensive use of incandescent lamp to be used with various electricity-saving lamps, therefore most lighting apparatus is also using traditional incandescent lamp lamp socket in life, in recent years along with LED lamp technology constantly is tending towards ripe, the manufacturing cost of LED lamp is more and more lower, led light source has plurality of advantages with respect to lighting source commonly used, to compare with the ordinary incandescent lamp of 15W, the incandescent lamp of forming with a plurality of led light sources not only the life-span longer, and there are not ultraviolet ray or an infrared light radiation, operating temperature range is wider, the more important thing is that its electric light conversion ratio is more near 100%, caloric value is far smaller than the power saving fluorescent lamp of incandescent lamp and equal illumination, the LED lamp body is long-pending less in addition, solid non-friable, therefore the packing of being more convenient for and transportation, have in the indoor application and do not launch infrared ray or ultraviolet ray, colour rendering is good, advantages such as light is softer, be suitable for the room lighting of various family expenses and industrial use, the LED lamp lighting device that does not utilize prior lamp holder to throw light in the market, many LED lighting apparatus can not be directly directly be connected use with traditional lamp socket.

The utility model content

Technical purpose of the present utility model provides a kind of can being installed in easily and has the LED bulb of realizing illuminations such as LED on the incandescent lamp screw lamp holder now.

For realizing above-mentioned technical purpose, the utility model LED bulb comprises the transparent circular Transparent lamp shade as lamp body, the alternating current-direct current transformer, lamp holder and some led light source modules, the led light source module comprises the LED lamp and has the LED lamp control circuit plate of LED control circuit, these some led light source modules are located at transparent circular Transparent lamp shade inside, lamp holder is fixedlyed connected with circular lampshade upper end, the input electrode of alternating current-direct current transformer is connected with lamp holder electrode, the input electrode of LED lamp control circuit is connected with the output of alternating current-direct current transformer, the output electrode of LED lamp control circuit is connected with the LED lamp.

These some LED control circuits are integrated on the circular circuit board, this circle circuit board is located in the circular Transparent lamp shade, identical parallel rectangular circuit board one side of being located at of some LED light irradiation directions, the input electrode of LED lamp control circuit plate is connected with lamp holder electrode, and output electrode is connected with the LED lamp.

Series connection mutually between the LED control circuit of these some led light source modules, parallel with one another between perhaps a plurality of LED control circuits, output with the alternating current-direct current transformer is connected afterwards, connect mutually by a plurality of LED, reach the LED lamp is combined illumination purposes with the conventional incandescent lamp socket proper number.

Beneficial effect: LED bulb of the present utility model is made traditional incandescent lamp form with the LED lamp, realize the illumination of LED lamp in conjunction with existing incandescent lamp screw lamp holder, make things convenient for the exchange between LED lamp and the incandescent lamp, can utilize existing traditional resource to use existing LED lamp and realize illumination, economize on resources and help the popularization of this LED bulb.

Relevant detailed content of the present utility model and technology are described as follows with regard to conjunction with figs. now.

Description of drawings

Fig. 1, be schematic perspective view of the present utility model;

Fig. 2, be the utility model circuit theory diagrams.

The specific embodiment

The utility model is that the concentrated installation back design team that is provided with of a plurality of LED lamps is dressed up traditional incandescent lamp form, to combine with existing incandescent lamp screw lamp holder easily, under the situation of not reinstalling lamp socket, utilize existing incandescent lamp screw lamp holder to realize LED lamp illumination purposes, be convenient to the popularization and the use of the LED lighting source of more energy-conservation and environmental protection.

Please refer to shown in Figure 1, be the schematic perspective view of a specific embodiment of the utility model LED bulb, the LED bulb among this embodiment includes transparent circular Transparent lamp shade 2, alternating current-direct current transformer (not shown), lamp holder 1 and the some led light source modules as lamp body.

Led light source module wherein comprises LED lamp 3 and lamp control circuit plate, the lamp-controlling circuit plate is provided with the luminous LED control circuit of driving LED lamp 3, this LED lamp 3 uses powered by direct current, therefore, the alternating current-direct current transformer is located on the circuit board, the output electrode of this alternating current-direct current transformer is connected with the input electrode of LED lamp control circuit, electric light source module and alternating current-direct current transformer together are located in the circular Transparent lamp shade 2, lamp holder 1 is fixedlyed connected with circular lampshade upper end, and the input electrode of alternating current-direct current transformer is connected with the electrode 10 of lamp holder 1.

For ease of this led light source module and alternating current-direct current transformer are located in the circular Transparent lamp shade 2, the control circuit of these a plurality of led light source modules is integrated on the circular circuit board 4 jointly, the alternating current-direct current transformer also is located on this circular circuit board, this circle circuit board 4 together is located in the circular Transparent lamp shade 2 with a plurality of led light source modules, this some LED lamp 3 is located at rectangular circuit board one side, it is approximate identical that the direction of its irradiation keeps, in use, direction of illumination can be concentrated on as far as possible the position that needs irradiation, under same consumption energy, guarantee that illuminated target area has enough brightness.
