Description

The 3PIN three-color LED lights that lamp bead can be lighted one by one

Technical field

It the utility model is related to LED technology field, more particularly to the 3PIN three-color LED lights that lamp bead can be lighted one by one.

Background technology

At present, 3PIN plug-in units lamp bead is generally double-colored light source, and the LED chip that it is encapsulated is typically in three kinds of colors of red, green, blue In select two kinds, 3PIN plug-in units lamp bead typically uses common cathode or common anode connection, due to by encapsulation technology, material, technologic limitation, Product is caused some defects to be in the application present, such as：Above-mentioned 3PIN plug-in units lamp bead cannot be distinguished by being common cathode in an assembling process Or common-anode, and 3PIN plug-in units lamp bead can only routinely encapsulate two kinds of colors.In addition, the three-color LED of in the market has used four Individual PIN, and be also required to the connection using common cathode or common-anode, the problem of equally existing above-mentioned 3PIN dual-colored LEDs lamp bead, And in order to realize the control of three-color LED light, it is necessary to increase a PIN than dual-colored LED lamp, both add material cost more, Circuit design cost is added again.

The Chinese utility model patent 201520315528.8 authorized on the 16th of September in 2015 discloses a kind of colors of 3PIN tri- LED and its lamp bead, including the first LED chip, the second LED chip and the 3rd LED chip, the negative pole of first LED chip For the first leads ends of 3PIN three-color LED lamps, the positive pole of the 2nd LED chips of connection, the negative pole of the 2nd LED chips is 3PIN The second pin end of three-color LED lamp, the negative pole for connecting the 3rd LED chips, the just extremely colors of 3PIN tri- of the 3rd LED chips 3rd leads ends of LED lamps, the positive pole for connecting the first LED chips, the first LED chips are red LED chips, second LED chips are blue led chip, the 3rd LED chips are green LED chip.The patent solves common cathode common anode and is difficult to area The problem of dividing simultaneously saves corresponding material cost and circuit design cost, but the connection can not individually light the 3rd LED core Piece, because when the 3rd LED chip is lighted（That is the 3rd pin is high level, second pin is low level）If the first pin is High level then lighted by the second LED chip, and the first LED chip is lighted if the first pin is low level, if the first pin is electrical Linkage section is in high-impedance state, it is likely that and the first LED chip can be lighted simultaneously with the second LED chip, because Realism Design In circuit, the level value of power supply will not just be the conducting voltage of LED chip, brighter in order to ensure that can send LED Light, level value typically all can be twice more than the threshold value turned on, therefore the design can not be realized and individually light the 3rd LED chip.

The content of the invention

Therefore, for it is above-mentioned the problem of, need to only connect three wires the utility model proposes a kind of and can be achieved to control three The 3PIN three-color LED lights that the lamp bead of colored lights pearl light on and off one by one can be lighted one by one.

To achieve the above object, the utility model employs following technical scheme：The colors of 3PIN tri- that lamp bead can be lighted one by one LED, including：The housing of LED, three in housing lamp beads connect with three lamp beads and pass three of housing and lead Line, three lamp beads are respectively lamp bead one, lamp bead two, lamp bead three, and three wires for passing housing are respectively first to lead Line, the second wire, privates, the first wire connection positive pole of lamp bead one, the negative pole of lamp bead two, the positive pole of lamp bead three, Negative pole, the positive pole of lamp bead two of the second wire connection lamp bead one, the negative pole of the privates connection lamp bead three.

It is further improved to be:The color that three lamp beads light later light is respectively：Lamp bead one for it is red, Lamp bead two is green, lamp bead three is blueness, i.e. three lamp beads are respectively red light pearl, green light pearl, blue lamp pearl.

It is further improved to be：During encapsulation, privates puts centre, and the first wire and the second wire put both sides.

By using preceding solution, the beneficial effects of the utility model are：The colors of 3PIN tri- that lamp bead can be lighted one by one LED, including：The housing of LED, three in housing lamp beads and connected with three lamp beads and pass the three of housing Bar wire, three lamp beads are respectively lamp bead one, lamp bead two, lamp bead three, and three bars of wires for passing housing are respectively One wire, the second wire, privates, the first wire connection positive pole of lamp bead one, the negative pole of lamp bead two, lamp bead three are just Pole, negative pole, the positive pole of lamp bead two of the second wire connection lamp bead one, the negative pole of the privates connection lamp bead three, institute Stating the color that three lamp beads light later light is respectively：Lamp bead one is red, lamp bead two is green, lamp bead three is blueness, That is three lamp beads are respectively red light pearl, green light pearl, blue lamp pearl, when the first wire is high level, the second wire is low level, the 3rd When wire is high level, green light pearl is bright, and red light pearl and blue lamp pearl are extinguished；When the first wire is low level, the second wire is high electricity When flat, privates is high level, red light pearl is bright, and green light pearl and blue lamp pearl are extinguished；When the first wire is high level, the second wire When for high level, privates being low level, blue lamp pearl is bright, and red light pearl and green light pearl are extinguished, can by connecting three wires Three lamp beads are lighted one by one to realize, the wire for not only needing to connect is few, reduces the probability to be broken down during installation, also reduces The design cost of the production cost of three-color LED light and related installation circuit, it is of the present utility model if not considering bright light order The 3PIN three-color LED lights that lamp bead can be lighted one by one can arbitrarily be installed regardless of pin order, as long as pressing level of the present utility model Design, can just realize and light tri coloured lantern one by one, and during encapsulation, privates puts centre, and the first wire and the second wire put two Side is such to be designed, in the case of not considering pin order when mounted, as long as the level state of more two kinds of pins is set, so that it may To realize the third lighting lamp state, i.e., when the level of both sides pin is low and high level alternating and the level of centre is low level, Green light and blue lamp while the state lighted just occurs, the combination of green glow and blue light forms the light of another color, makes three-color LED Lamp can send the light of four kinds of colors.
