Description
Technical field
The utility model relates to a kind of light emitting diode bulb.
Background technology
At present, for reaching non-polar object in light emitting diode bulb, all adopt the bridge circuit connecting luminous diode (or chip) be constituted by a diode.But, because the bridge circuit be made up of 4 groups of diodes unavoidably occupies larger bulb space.
Utility model content
The purpose of this utility model solves in prior art to cause bulky problem because using diode composition bridge circuit, provides a kind of light emitting diode bulb of Novel electrodeless high brightness.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of light emitting diode bulb, it is characterized in that, include, lamp socket end face, described lamp socket end face has the first light-emitting diode chip for backlight unit, the second light-emitting diode chip for backlight unit, the 3rd light-emitting diode chip for backlight unit, the 4th light-emitting diode chip for backlight unit, the 5th light-emitting diode chip for backlight unit and the 6th light-emitting diode chip for backlight unit.Wherein, described first light-emitting diode chip for backlight unit, described second light-emitting diode chip for backlight unit, described 3rd light-emitting diode chip for backlight unit, described 4th light-emitting diode chip for backlight unit form bridge circuit, the input termination power of described bridge circuit, the 5th light-emitting diode chip for backlight unit, described 6th light-emitting diode chip for backlight unit and the first resistance described in the output termination of described bridge circuit.The first described light-emitting diode chip for backlight unit ~ the 6th light-emitting diode chip for backlight unit is the device of same model, its rated current I
f=30mA; Reverse withstand voltage V
r=40V; The resistance R=1.5K Ω of described first resistance; Power consumption W=0.25W: the operating current I under rated voltage condition
g=10mA.
Compared with prior art, advantage of the present utility model at least comprises following: non-polar condition lower volume is little, and brightness is high.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
See the principle signal that Fig. 1 is a kind of small-size electrodeless high brightness LED lamp bubble, it is characterized in that the bridge circuit being connected in series power supply is made up of four groups of light-emitting diode chip for backlight unit D1-D4, the output of bridge circuit is light-emitting diode chip for backlight unit D5, D6 of two series connection and the resistance R of a series connection.When by illustrated forward rated voltage input, D1, D3 forward conduction in bridge circuit also can be ignited; D2, D4 are the cut-off that is oppositely energized, because of the reverse withstand voltage V of selected LED chip
r=40V, under the reverse power on condition that this is specified, can not be breakdown; Otherwise, when pressing rated reverse voltage energising, D2, D4 conducting; D1, D3 end; The power supply no matter inputted just is connecing or reversal connection, D5, D6 of being connected with bridge circuit are all in forward conduction can by the state ignited, ensure that thus no matter under forward and reverse rated voltage initial conditions, all the time four groups of light-emitting diode chip for backlight unit are had to ignite under the driving of operating current, achieve high brightness and non-polar target, resistance R then assume responsibility for the effect of current limliting in the line.
Below only have expressed execution mode of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
