Description

The decorative chain device

[technical field]

The relevant a kind of decorative chain device of the utility model system is a kind of decorative chain device with multiplication of voltage design especially.

[background technology]

Light emitting diode (Light Emitting Diode; LED) mainly be to utilize the electronics of semi-conducting material, the combination in electric hole, electronics can fall to than the low energy rank, discharges light energy simultaneously and produces illuminating effect.And, owing to LED can provide light sources of different colors according to the forbidden band energy of material, so current LED can provide the light source of full-colorization series to select for the consumer, and LED is compared to conventional bulb, have volume little, than power saving, anti-ly fall, chemiluminescence, the fast advantage of reaction speed, so widely apply on multiple product gradually.

Wherein, LED just is applied on the decorative chain, is known a kind of decorative chain device 10 as shown in Figure 1, comprises that an attaching plug 12 inserts 14 with a tail that couples mutually, reaches a power supply changeover device 16 and is coupling an attaching plug 12 and a LED serial 18.Power supply changeover device 16 is in order to after converting alternating current to direct current, exports to LED serial 18.

Under original voltage, in case desire increases the light emitting diode number of lamp string, will cause the situation of light emitting diode generation luminance shortage, so adopt mode to increase voltage swing exactly usually, just the be increased light emitting diode number of lamp string can not reduce brightness again, and is right, the mode of this raising voltage can expend more electric power, increases the cost expenditure.

Therefore, the utility model proposes a kind of decorative chain device of innovation, to solve above-mentioned restriction and disappearance.

[summary of the invention]

The purpose of the utility model ties up to provides a kind of decorative chain device, mainly is the design that sees through voltage-multiplying circuit, and the light emitting diode number of light emitting diode serial is improved, and need not improve supply voltage, so can reduce cost.

Disclosing the decorative chain device according to the utility model, be to comprise that the tail that an attaching plug and that receives alternating voltage couples mutually inserts, and one couples attaching plug and the slotting light emitting diode serial of tail.Wherein, attaching plug has first capacitor that one first diode and couples mutually, and tail is inserted has second capacitor that one second diode and couples mutually, gives this light emitting diode serial with the DC voltage that is output as alternating voltage peak twice size by this.

The purpose of the utility model or other purpose know for the knowledgeable usually for this skill, and it is apparent and easy to know reading after the detailed content of following examples.

Previous general introduction and ensuing being described in detail all are examples, so that can further explain the patent request item of the utility model.

[specific embodiment]

Please refer to Fig. 2, is the three-dimensional appearance schematic diagram of the decorative chain device of the utility model.As shown in the figure, the decorative chain device 20 of the utility model comprises that one has the attaching plug 22 of pair of conductive inserted sheet 23, one tail that couples attaching plug 22 inserts 24, wherein tail slotting 24 can plug for another plug, an and light emitting diode serial 26, it is made up of a plurality of light emitting diode 26a, and one of light emitting diode serial 26 end couples attaching plug 22, and the other end couples tail and inserts 24.Wherein, light emitting diode 26a system is selected from the light emitting diode of white light emitting diode, red light-emitting diode, blue light-emitting diode, green light LED, Yellow light emitting diode or other colors.

, be the circuit diagram of the decorative chain device of the utility model please together with reference Fig. 3.As shown in the figure, attaching plug 22 have diode 221 that a rectification uses and and its capacitor C1 that couples mutually, tail insert 24 have diode 241 that a rectification uses and and its capacitor C2 that couples mutually, wherein capacitor C1 equates with the capacitance of C2, is used to store electric charge and has filter function.Attaching plug 22 receives alternating voltage via conduction inserted sheet 23, diode 221 receives alternating voltage and with the control sense of current capacitor C1 is charged, to export a voltage swing is that the DC voltage of the twice of alternating voltage peak is given light emitting diode serial 26, in like manner, tail inserts 24 from attaching plug 22 reception alternating voltages, diode 241 receives alternating voltages and with the control sense of current capacitor C2 is charged, and is that the DC voltage of the twice of alternating voltage peak is given light emitting diode serial 26 to export a voltage swing.Thus, light emitting diode serial 26 the light emitting diode number just can double.

Hence one can see that, the utility model is put the voltage-multiplying circuit of being made up of capacitor and diode by plugging at attaching plug and tail, the DC voltage that the twice size can be provided is to the light emitting diode serial, the luminosity of light emitting diode can be brighter by this, or also can increase the number of light emitting diode, and need not increase supply voltage, increase cost burden.

The embodiment of the above only is the technological thought and the characteristics of explanation the utility model, its purpose makes the personage who has the knack of this skill can understand appearance and enforcement according to this within the utility model, when can not with the claim of qualification the utility model, promptly the equalization of doing according to the spirit that the utility model disclosed generally changes or modifies, and must be encompassed in the claim of the utility model.
