[specific embodiment]
Aforementioned and other technologies content, characteristics and effect of the present utility model in the following detailed description that cooperates with reference to a graphic embodiment, can clearly present.
Before the utility model is described in detail, be noted that in the following description content similar or components identical will be represented with identical label.
Consulting shown in Figure 2ly, is an embodiment of the utility model spot device, and this spot device 2 mainly comprises an insulation transparent body 20, a positive power line 21, a negative power line 22 and a lamp string 23.
Insulation transparent body 20 is flexible hoses, its tube wall (being between the inside and outside edge) has a thickness, and by a tube wall encirclement formation accommodation space 201, and present embodiment is on general the use, insulation transparent body 20 is to be a long measure (being fundamental length) with 6 meters, and the length of positive and negative power line 21,22 is long slightly than insulation transparent body 20, and it is embedded in respectively between the inside and outside edge of insulation transparent body 20 (in the tube wall), only exposes the rear and front end.
Lamp string 23 is to be set in the insulation transparent body 20, and its two ends are connected with an end of positive and negative power line 21,22 respectively.Lamp string 23 is made up of the light-emitting component of a plurality of series connection; and has the length suitable with insulation transparent body 20; and these light-emitting components can be LED crystal particle or traditional mini bulb; and since the more traditional in the use mini bulb power saving of LED crystal particle and life-span long; therefore be to be example with the LED crystal particle in the present embodiment, and these LED crystal particles are respectively by a light-permeable insulating cement material (figure does not show) encapsulation.Particularly, more be connected in series a fuse 26 on the lamp string 23, this fuse 26 is to be connected between lamp string 23 and the positive power line 21, and in the present embodiment, the rated value of fuse 26 is 250 volts/0.25 ampere.
In addition, spot device 2 more comprises a male joint 24 and a female joint 25,24 groups of ends that are located at insulation transparent body 20 of male joint, and it comprises two male terminals 241,242 that are connected with an end of positive and negative power line 21,22 respectively.25 groups of other ends that are located at insulation transparent body 20 of female joint, it comprises two female terminals 251,252 that are connected with the other end of positive and negative power line 21,22 respectively.Therefore, the user can be connected in series a plurality of spot devices 2 mutually by the male joint 24 and the female joint 25 of spot device 2, forming required spot length, and elasticity adjustment and change the length and the moulding of spot according to circumstances.
And as shown in Figure 2, spot device 2 can be connected with a power connector 3, and this power connector 3 comprises a plug 31, a rectification and mu balanced circuit 32 and a female joint 33.Plug 31 is in order to be connected with a power end (figure does not show), and rectification and mu balanced circuit 32 are connected with plug 31, carry out rectification and voltage stabilizing in order to the power supply that power end is provided, and give connected female joint 33 to export a burning voltage.And the male joint 24 of spot device 2 is to be connected with the female joint 33 of power connector 3, and it is luminous to drive lamp string 23 with the power supply of accepting power end.In addition, be to ensure the Environmental security of power end placement, between the rectification of power connector 3 and mu balanced circuit 32 and female joint 33, more be connected in series a fuse 34, and in the present embodiment, the rated value of fuse 34 is 250 volts/1.6 amperes.
Whereby, as shown in Figure 3, when the user composes in series a long linear spot with a plurality of spot devices 2, and when connecting power connector 3, after the plug 31 of power connector 3 connects power end, these lamp strings 23 that the electric power that power end provides will drive in these spot devices 2 are luminous, at this moment, if one of them lamp string 23 of these spot devices 2 is short-circuited, make and flow through the electric current of lamp string greater than 0.25 ampere-hour, the fuse 26 that is connected with this lamp string 23 will blow greater than its rated value (0.25 ampere) voluntarily because of the electric current that passes through, make to form between the spot device that is short-circuited and the positive power line 21 and open circuit, so, the unlikely related fuse 34 of power connector 3 that makes because of continuing to increase to exceeding its rated value (1.6 amperes), the electric current that passes through is blown, can not cause cutting off the power supply between power connector 3 and other spot devices 2, make other spot devices 2 still can operate as normal when spot device is short-circuited in a certain (or some).
In addition; when short circuit is when occurring on the positive and negative power line 21,22; be the Environmental security of protection power end, excessive short circuit current will make the fuse 34 that is connected between rectification and mu balanced circuit 32 and the female joint 34 blow, and power end will be unlikely suffer super-high-current and cause danger.
In sum, the utility model spot device 2 is by series connection one fuse 26 on its lamp string 23, make when a plurality of spot devices 2 are used by serial connection, when if wherein a spot device 2 is short-circuited, the fuse 26 that is connected in series with its lamp string 23 can blow in good time, the spot device and the power end (being positive power line 21) of this short circuit are disconnected, and the fuse 34 that does not cause power connector 3 disconnects because of the super-high-current that the spot device of short circuit produces, thereby can avoid influencing the power supply of other spot devices, these spot devices are short-circuited when damaging at a certain (or some) spot device, still can keep operate as normal.
