Abstract
Provided is a durable ornamental festoon lamp. In an insulation shell, a current-limiting resistor (3), a diode (6) and an iron oxide wire (4) are in series connection and then are in parallel connection with a light-emitting diode (2). Thus, in a group of lamps even though a lamp or a plurality of lamps are in disconnection, the phenomenon that the whole lamps cannot work is avoided or a power supply short circuit is avoided.
Description
Affiliated technical field:
The utility model relates to a kind of color lamp, especially the color lamp that can comprehensively not damage because wherein one or more color lamps open circuit.
Background technology:
At present, nearly all ornamental festoon lamp all adopts series-parallel connection, and in one group of lamp, as long as one is opened circuit, then whole color lamps all can't be worked in this group.Though it is in parallel with bulb that existing durable ornamental festoon lamp has added the oxidation iron wire, overcome the problems referred to above, in one group,, then whole color lamps can be burnt out, and the danger that causes short circuit is arranged if there are a plurality of color lamps to open circuit.
Summary of the invention:
In order to overcome existing ornamental festoon lamp damage in a group, can not work and have now durable color lamp can all damage and may cause short circuit under a plurality of lamp damaged conditions deficiency all, the utility model provides a kind of durable ornamental festoon lamp, even this durable ornamental festoon lamp only also can operate as normal during surplus the next light a group, and can avoid because color lamp burns out and short circuit.
The scheme that its technical problem that solves the utility model adopts is: in insulation crust (1), and each light emitting diode (2) below branch road that is connected into by diode (6) protective resistance (3) in parallel.The branch road that this diode (6) and protective resistance (3) are connected into links to each other with circuit (as Fig. 1) with iron oxide lead (4), and all the other are partly identical with existing common ornamental festoon lamp.During the color lamp operate as normal, diode branch opens circuit; But in a single day the color lamp place opens circuit, and the voltage of 220V is added in iron oxide lead (4) two ends, with its puncture, electric current is from the diode branch process, and circuit reverts to path, because the forward voltage drop of diode, each part voltage is constant in the circuit, so can not cause whole lamps to damage or short circuit.Like this, even but whole group lamp only remains also operate as normal of the next one.
The beneficial effects of the utility model are, in the time of can one or more lamps open circuit in one group of lamp, make other lamp operate as normal, also can not cause short circuit.In each stand-by circuit, only adopt diode (6) protective resistance (3) iron oxide lead (4), simple in structure.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified
Fig. 1 is the profile at the utility model color lamp place
Fig. 2 is the some of circuit diagram of the present utility model
Among the figure, (1) insulation crust; (2) light emitting diode; (3) protective resistance; (4) iron oxide lead; (5) lead; (6) diode; (7) commercial power interface; (8) control box.
The specific embodiment
In Fig. 1, each portion of element is arranged by figure, and the interior the superiors of shell (1) are that light emitting diode (2) lower floor is diode (a 6) protective resistance (3).
In Fig. 2, control box (8) links to each other with commercial power interface (7), and iron oxide (4) protective resistance (3) diode (6) series connection back is in parallel with light emitting diode (2), and a plurality of such circuit are connected with control box (8).Protective resistance (3) resistance should be about 5 Ω.
Claims (2)
1. durable ornamental festoon lamp; light emitting diode (2) is connected with control box (8), it is characterized in that, locates one in parallel at each Light-Emitting Diode (2) and connects with iron oxide lead (4); circuit by diode (6) and protective resistance (3) are connected into is connected with control box (8).
2. a kind of durable ornamental festoon lamp according to claim 1 is characterized in that, at the color lamp place, light emitting diode (2) is above stand-by circuit.
