Abstract
The utility model provides a double-color LED which relates to a semiconductor luminous component, particularly to an LED. Two different monochromatic LEDs are arranged in a packaging structure, wherein the positive electrode of the first LED is connected with the negative electrode of the second LED, and then is led out by a leading foot outwards. The negative electrode of the first LED is led out by another leading foot outwards; the positive electrode of the second LED is led out by a third leading foot outwards; or the negative electrode of the first LED is connected with the positive electrode of the second LED, and then is led out by another leading foot outwards. The double-color LED solves the problem that the existing double-color LED with four leading feet has complex connection relation.
Description
Technical field
The utility model relates to a kind of light emitting semiconductor device, particularly relates to a kind of light-emitting diode.
Technical background
Existing dichromatic LED, owing to be that two different monochromatic light-emitting diodes are set in an encapsulating structure, two electrodes of every light-emitting diode are outwards drawn by leading foot respectively.For example, the disclosed number of patent application of Chinese utility model patent specification CN 2084660U is 91202435.6, and name is called the technical scheme of " dichromatic LED ", is like this.Dichromatic LED is generally used for occasions such as caution, advertisement and decoration, during use often a kind of monochromatic light of color embody a kind of implication or effect, the monochromatic light of another kind of color embodies another kind of implication or effect, just instructions for use can have been satisfied, therefore a dichromatic LED will connect four leading foots, seems too loaded down with trivial details in actual use.
The utility model content
The utility model aims to provide and a kind ofly can alternately send two kinds of color monochromatic light after energising, and the simple dichromatic LED of annexation.
The technical solution of the utility model is: dichromatic LED, two different monochromatic light-emitting diodes are set in the encapsulating structure, outwards draw by a leading foot after wherein the negative electrode of the positive electrode of first light-emitting diode and second light-emitting diode interconnects, the negative electrode of first light-emitting diode is outwards drawn by the another leading foot, and the positive electrode of second light-emitting diode is outwards drawn by the 3rd leading foot.
Further: dichromatic LED, two different monochromatic light-emitting diodes are set in the encapsulating structure, outwards drawn by a leading foot after wherein the negative electrode of the positive electrode of first light-emitting diode and second light-emitting diode interconnects, the positive electrode of the negative electrode of first light-emitting diode and second light-emitting diode interconnects the back and is outwards drawn by the another leading foot.
The utility model dichromatic LED, adopt the positive electrode of a light-emitting diode and the negative electrode of another light-emitting diode to interconnect the structure that the back is outwards drawn by a leading foot, externally saved the connecting line of a leading foot, in occasions such as the billboard that uses this dichromatic LED in a large number, warning mark, decorative chains, not only can significantly reduce numerous and diverse property of assembly working, can also reduce cost significantly; Internally saved the internal connection line of an electrode and a leading foot, simplified encapsulation operation, reduced production costs.Particularly the positive electrode of two light-emitting diodes adopts mutual reversed polarity to be connected each structure of outwards being drawn by a leading foot of back with negative electrode, externally saved the connecting line of two leading foots, internally saved the internal connection line of two electrodes and two leading foots, effect is more remarkable.Dichromatic LED of the present utility model also is fit to the demonstration of tri-state logic circuit and bipolar circuit state except that being used for the General Logic circuit, have wide range of commercial market.
Description of drawings
Fig. 1 is the electric structure chart of the utility model dichromatic LED embodiment one.
Fig. 2 is the electric structure chart of the utility model dichromatic LED embodiment two.
Fig. 3 is the electric structure chart that a kind of typical case of Fig. 2 embodiment uses.
Embodiment
One, embodiment one
The electric structure of first embodiment of the utility model dichromatic LED, as shown in Figure 1.This dichromatic LED D1, a red light emitting diodes 110 and a green LED 120 are set in an encapsulating structure, outwards draw by a leading foot 101 after wherein the negative electrode 121 of the positive electrode 111 of red light emitting diodes 110 and green LED 120 interconnects, the negative electrode 112 of red light emitting diodes 110 is outwards drawn by another leading foot 102, and the positive electrode 122 of green LED 120 is outwards drawn by the 3rd leading foot 103.
Two, embodiment two
The electric structure of second embodiment of the utility model dichromatic LED, as shown in Figure 2, this dichromatic LED D2, a red light emitting diodes 210 and a green LED 220 are set in an encapsulating structure, outwards drawn by a leading foot 201 after wherein the negative electrode 221 of the positive electrode 211 of red light emitting diodes 210 and green LED 220 interconnects, the negative electrode 212 of red light emitting diodes 210 interconnects the back with the positive electrode 222 of green LED 220 and is outwards drawn by another leading foot 202.
In a kind of typical case of present embodiment shown in Figure 3 used, d type flip flop T was as the controller of dichromatic LED D2, and resistance R 21 is pull-up resistors of d type flip flop T output Q end.Resistance R 22 is current-limiting resistances of dichromatic LED D2.Resistance R 23 is the identical divider resistances of resistance value with resistance R 24, and the current potential of the tie point of the leading foot 201 of they and dichromatic LED D2 is VC/2.D type flip flop T output Q end output is during near earthy low level, and the red light emitting diodes 210 of dichromatic LED D2 is luminous.When d type flip flop T output Q end was exported near the high level of positive supply+VC, the green LED 220 of dichromatic LED D2 was luminous.Change the signal level of d type flip flop T input D end in good time, just can control photochromic that dichromatic LED D2 sends.Obviously, all the dichromatic LED than original four leading foots is simple to adopt behind the present embodiment control relation and electrical connection.
The above only is the utility model preferred embodiment, does not limit the scope that the utility model is implemented with this, and the equivalence of doing according to the technical solution of the utility model and description changes and modification, all should belong to the scope that the utility model is contained.
