LED lamp
Technical field
The present invention relates to a kind of LED lamp, refer to especially a kind of LED lamp that can flexible transformation bright dipping form.
Background technology
LED source can produce emerging third generation light source high-power, high brightness as a kind of, there is the advantage such as energy-saving and environmental protection, long-life, meet the theme of energy-conserving and environment-protective now, be used widely and fast development in lighting field, and have the trend of conventional light source such as replacing incandescent lamp, fluorescent lamp.
Traditional LED lamp comprises the multiple light emitting diode module that fit together according to set mode, in the time that light emitting diode module is in running order, because all light emitting diode module are fixed on the relevant position of light fixture securely, make the too unification of bright dipping form of light fixture, cannot flexible adaptation the lighting demand of different occasions.
Summary of the invention
In view of this, be necessary to provide a kind of convenient LED lamp of installing, dismantling light emitting diode module.
A kind of LED lamp, it comprises light fitting body and light emitting diode module, on this light fitting body, offer a pair of jack, one side of this light emitting diode module has a pair of plug, when installation, by the plug of this light emitting diode module being inserted in the jack of this light fitting body, this light emitting diode module is connected with this light fitting body conduction; When dismounting, disconnect light emitting diode module and be connected with the conduction of this light fitting body by the plug of this light emitting diode module is extracted from the jack of this light fitting body.
Compared with prior art, LED lamp of the present invention can be as required, by the plug of light emitting diode module being inserted in the jack of light fitting body or the plug of light emitting diode module being extracted from the jack of light fitting body, can neatly the light emitting diode module of varying number be assembled on light fitting body or from light fitting body and be dismantled, thereby make the bright dipping form of light fixture more diversified, thereby meet the lighting demand of multiple different occasions.

Detailed description of the invention
As shown in Figure 1, the LED lamp for room lighting of one embodiment of the invention comprises a locating dowel 10, a light fitting body 20 being connected with locating dowel 10 and the multiple light emitting diode module 30 that are connected with this light fitting body 20.
Described locating dowel 10 is a cylindric metal bar, and its bottom wears and is fixedly connected on light fitting body 20, and its top is used for being connected on building top and by this LED lamp location.
This light fitting body 20 comprises a voltage transformation module 22 and is arranged on multiple light emitting diodes 24 of these voltage transformation module 22 bottoms.This voltage transformation module 22 is for alternating current is converted into direct current, so that light emitting diode 24 and the light emitting diode module 30 required dc source of working to be provided.Two relative horizontal side (left side and right side) of this voltage transformation module 22 are respectively offered a pair of jack 220.The plurality of light emitting diode 24 can be configured to send the light of same color as required, or sends the light of different colours.
Each light emitting diode module 30 comprise a rectangle body 31, be arranged on multiple light emitting diodes 32 of these body 31 bottom sides and a horizontal side (left side) of this body 31 extend horizontally away certainly a pair of plug 36.Another horizontal side (right side) corresponding plug 36 of this body 31 is offered a pair of jack 34.The light emitting diode 32 of each light emitting diode module 30 can be configured to send the light of same color as required, or sends the light of different colours.
Figure 2 shows that the circuit theory diagrams of this LED lamp, this voltage transformation module 22 comprises a rectifier bridge U1 and a conversion chip U2.The model of this conversion chip U2 is DS8643.This rectifier bridge U1 comprises end to end four diode D1~D4.The pair of terminal of this rectifier bridge U1 is connected with alternating current, and another pair of terminal connects respectively pin H and the pin E of conversion chip U2.The two ends of capacitor C 1 are connected between this another pair of terminal of rectifier bridge U1, to carrying out filtering from the voltage of rectifier bridge U1 output.The pin D of this conversion chip U2 and pin E ground connection.The two ends of the series arm of resistance R 1, diode D5 and inductance L are connected with pin H and the pin A of this conversion chip U2 respectively.The grid G of FET Q connects the pin C of this conversion chip U2, and the drain D of FET Q is connected between diode D5 and inductance L, and the source S of FET Q is by resistance R 2 ground connection.The two ends of the series arm of the plurality of light emitting diode 24 are connected with two outputs of this voltage transformation module 22 respectively.The series arm of the light emitting diode 32 of each light emitting diode module 30 and the series arm of the plurality of light emitting diode 24 are in parallel.
In LED lamp of the present invention, on described light fitting body 20, offer a pair of jack 220, this light emitting diode module 30 has a pair of plug 36, when installation, by the plug of this light emitting diode module 30 36 is inserted, the jack 220 of this light fitting body 20 is interior to conduct electricity this light emitting diode module 30 to be connected with this light fitting body 20; When dismounting, disconnect light emitting diode module 30 and be connected with the conduction of this light fitting body 20 by the plug of this light emitting diode module 30 36 is extracted from the jack 220 of this light fitting body 20.The plug 36 of each light emitting diode module 30 can insert in the jack 220 of light fitting body 20, the plug 36 of each light emitting diode module 30 also can insert in the jack 34 of other light emitting diode module 30, thereby more easily this light fitting body 20 is fitted together with multiple light emitting diode module 30, light fitting body 20 is connected with multiple light emitting diode module 30 conductions.Also the plug of light emitting diode module 30 36 can be extracted from the jack 220 of light fitting body 20 or extracted from the jack 34 of other light emitting diode module 30, thereby more easily this light fitting body 20 be dismantled with multiple light emitting diode module 30.Therefore, LED lamp of the present invention can be as required, neatly the light emitting diode module of varying number 30 is assembled on light fitting body 20 or from light fitting body 20 dismountings, makes the bright dipping form of light fixture more diversified, thereby meet the lighting demand of different occasions.
