Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the technical solution of the utility model is described in detail.
As depicted in figs. 1 and 2, the nonpolarity LED lamp bead of a kind of two pins that this utility model embodiment provides, including first
Pin the 7, second pin 8 and covering 1；The top of described first pin 7 and the second pin 8 is packaged in covering 1, the first pin 7
It is exposed to covering 1 outside with the bottom of the second pin 8；The upper end of the first pin 7 is provided with mounting platform, and mounting platform is provided with
First luminescence chip 2 and the second luminescence chip 3；The positive pole of described first luminescence chip 2 passes through bond wire line 4 and the first pin
7 electrical connections, the negative pole of the first luminescence chip 2 is electrically connected with the second pin 8 by bond wire line 4；Described second luminescence chip 3
Negative pole electrically connected with the first pin 7 by bond wire line 4, the positive pole of the second luminescence chip 3 passes through bond wire line 4 and the
Two pins 8 electrically connect.I.e. first luminescence chip 2 and the electrode reverse parallel connection of the second luminescence chip 3.
Specifically, as in figure 2 it is shown, in this utility model embodiment, the end face of described mounting platform is provided with a depressed part
6, described first luminescence chip 2 and the second luminescence chip 3 are installed in depressed part 6.
Further, described first luminescence chip 2 and the second luminescence chip 3 are monochromatic luminescence chip, in described depressed part 6
It is filled with fluorescent material 5.
Further, the housing that described covering 1 becomes for epoxide-resin glue system.
Further, described first luminescence chip 2 can be dissimilar with the second luminescence chip 3 and have Bu Tong luminous
The chip of color, it is also possible to be same type and the chip with identical glow color.
As it is shown on figure 3, when the nonpolarity LED lamp bead of multiple two pins of this utility model offer is connected on DC power-supply system
In, and system forward power (the i.e. first pin 7 connects positive pole, the second pin 8 connects negative pole) time, the first luminescence chip 2 turns on luminescence,
Second luminescence chip 3 reversely ends and does not work.
As shown in Figure 4, the nonpolarity LED lamp bead of multiple two pins provided when this utility model is connected on DC power-supply system
In, and system reverse power (the i.e. first pin 7 connects negative pole, the second pin 8 connects positive pole) time, the first luminescence chip 2 reversely ends
Not working, the second luminescence chip 3 turns on luminescence.
I.e. when externally fed is direct current, no matter polarity of voltage how, in the first luminescence chip 2 and the second luminescence chip 3
One can turn on luminescence, another does not works because of voltage reversal.Therefore, the nonpolarity LED of two pins of the present utility model
Both positive and negative polarity can be distinguished when pearl is installed in DC power-supply system, simplify installation process.
As it is shown in figure 5, when the nonpolarity LED lamp bead of multiple two pins of this utility model offer is connected on ac power supply system
Time middle, at the positive half period of alternating current, the first luminescence chip 2 turns on luminescence, and the second luminescence chip 3 reversely ends and do not works；?
The negative half-cycle of alternating current, the first luminescence chip 2 reversely ends and does not work, and the second luminescence chip 3 turns on luminescence；I.e. first is luminous
Chip 2 and the second luminescence chip 3 are luminous at positive half period and negative half-cycle alternate conduction successively.
Therefore, it is same type and the chip with identical glow color when the first luminescence chip 2 and the second luminescence chip 3
Time, LED lamp bead that two pins of the present utility model is nonpolarity understands image persistence luminescence and without stroboscopic phenomenon in ac power supply system.When
When first luminescence chip 2 and the second luminescence chip 3 are dissimilar and have the chip of different glow color, it is also possible to by right
Alternating current is modulated, and makes the nonpolarity LED lamp bead of two pins of the present utility model realize color blending effect in ac power supply system.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, common for this area
For technical staff, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
