When any lamp fitting of the luminous diode in the lamp string is failed or the electrode is wrong connected during assembly, the entire lamp string can also be normally operated for lighting.
Description
The utility model relates to a kind of led lamp that supplies the lamp string to use, and is especially a kind of between two leads of this light emitting diode bulb, has the lamp string led lamp of Elecrical connector.
Light emitting diode bulb is because hang down working temperature, and high-luminous-efficiency and height are economized electrical efficiency, and are applied in different fields widely.Generally, light emitting diode bulb has the electrode cable of both positive and negative polarity, and that the polarity of lead must connect correct this light emitting diode bulb that could allow is shinny, when just the light-emitting diode of light emitting diode bulb must be forward bias voltage drop, just have current lead-through and luminous, otherwise when reverse bias, because of equivalent resistance infinity non-conducting electric current almost, therefore can be not luminous.If for the polarity wrong that a light emitting diode bulb is wherein arranged by the lamp string that most light emitting diode bulb was formed by connecting, when just light emitting diode bulb is reverse bias, light-emitting diode on the lamp string can be not luminous, because the light emitting diode bulb of this polarity wrong can be blocked the conduction of electric current, making does not have on the whole lamp string loop electric current to flow.
Therefore in the manufacture process of LED light string, if the polarity wrong of a light emitting diode bulb is arranged or lost efficacy non-conductively, then the light-emitting diode of whole string all can not be shinny.For this reason, the staff must check the polarity of each light emitting diode bulb in the LED light string to connect, so that find out the light emitting diode bulb of polarity wrong or the light emitting diode bulb of disabler.This can need great amount of manpower man-hour, and can significantly increase manufacturing cost.
Main purpose of the present utility model is to provide a kind of special led lamp to use to the lamp string, has an Elecrical connector in this led lamp, its resistance is greater than the equivalent resistance of light-emitting diode under forward bias voltage drop, and less than the equivalent resistance of light emitting diode bulb under reverse bias.Generally, the light emitting diode bulb forward bias voltage drop under the 20mA operating current is from 1.7 to 6V, along with the kind of light-emitting diode and form different and different.If the light emitting diode bulb forward bias voltage drop under the 20mA operating current is 2V, then equivalent resistance is 100 Ω (being R=2/0.02).This Elecrical connector is positioned between the both positive and negative polarity lead of light emitting diode bulb.Can use alternating current system or dc system by the lamp string that this special led lamp constituted.Because the Elecrical connector between light emitting diode bulb both positive and negative polarity lead exists, so when a certain light emitting diode bulb in the lamp string lost efficacy or assembling in during electrode connection error, remaining light emitting diode bulb still can normal running and luminous in the lamp string, because electric current can be through the Elecrical connector on the light emitting diode bulb of polarity wrong.
Further purpose of the present utility model is to provide a kind of led lamp with Elecrical connector, and this Elecrical connector has enough big resistance.When a certain light emitting diode bulb in the lamp string lost efficacy or assembling in during electrode connection error, remaining light emitting diode bulb still can normal running and luminous in the lamp string.Therefore, in manufacture process, the light emitting diode bulb of finding out electrode connection error in the assembling or disabler that can be very fast is because the light that has only this light emitting diode bulb to export is different with other light emitting diode bulb.
Fig. 1 is the traditional circuit diagram of light emitting diode bulb under correct assembling, wherein electric current can flow through light emitting diode bulb, and light emitting diode bulb can be luminous, the anodal stent foot of general LED light lamp is longer, and the negative pole stent foot is shorter, in order to distinguish the polarity of light-emitting diode.
Fig. 2 is the traditional circuit diagram of light emitting diode bulb under the polarity of electrode assembly defect, and wherein electric current can't flow through light emitting diode bulb, and light emitting diode bulb can't be luminous.
Fig. 3 demonstrates the lamp string that is connected in series and is formed by many traditional light emitting diode bulbs, and the polarity of electrode assembly defect of a traditional light emitting diode bulb is wherein arranged, and just light emitting diode bulb that must be all can not be normally luminous.
Fig. 4 A is the exploded view of the utility model led lamp.
Fig. 4 B is the stereogram after the assembling of the utility model led lamp.
Fig. 5 is the lamp string that utilizes the utility model light fixture to be constituted, the polarity of electrode assembly defect that a led lamp of the present utility model is wherein arranged, but except the led lamp of this polarity of electrode assembly defect, all the other all led lamps can both be luminous and operate as normal.
Fig. 6 is first preferred embodiment of the present utility model.
Fig. 7 is second preferred embodiment of the present utility model.
