Description
Technical field
The utility model belongs to field of semiconductor materials, and in particular to a kind of five foot Full-color LED encapsulation structures.
Background technology
LED（Light emitting diode）Encapsulation refers to the encapsulation of luminescence chip, and existing all-colour LED is by red light chips, green light core
Piece, blue chip are encapsulated in a lamp bead, and showing a variety of colors by the different hybrid modes of three primary colours comes out.Due to three
Primary colours light mixng proportions is different, so if all-colour LED lamp bead will realize color change at present, need by be operated alone chip come
Control RGB light mixng proportions.
Current existing mode is to be equipped with all-colour LED, driving chip, current resistor etc. respectively on a printed circuit.
During use, all-colour LED is driven according to pre-set programs by driving chip, is then become by the light of multiple all-colour LEDs
Change and forms a complete LED display.But need to be mounted so that driving chip, current-limiting resistance lamp components, are caused full-color
Hypertelorism between LED lamp bead, LED display pixel is not high, can not well show careful image.Soft pcb board simultaneously
It is easy distortion, bending, device solder joint poor contact is be easy to cause, causes circuit maloperation.Meanwhile driving chip is exposed, easily by
To electromagnetic interference（EMI）.So how driving chip, LED lamp bead, current-limiting resistance to be placed in same lamp bead, lamp bead is reduced
Use space is a very significant project.
LED light will produce power consumption during powering on use, and a part of power consumption is discharged in the form of optical signal, another
Part signal is discharged outward in the form of thermal energy.This partial heat energy can be such that LED light temperature increases.LED temperature is excessively high, can make LED
Luminous efficiency reduces, and generates apparent light decay, or even damage.Meanwhile LED light is mostly with epoxy encapsulation, if temperature is super
Cross solid phase transition temperature（Tg）, encapsulating material can to rubber-like change and coefficient of thermal expansion rise sharply, so as to cause LED open circuit or
Person is failed.Since all-colour LED internal illumination chip has 3, also a driving chip, so this problem can be protruded more.
So how to reduce LED power consumptions, reduces operating temperature and be also an important issue project.
There are red light chip, green light chip and blue lamp chip in full-color LED lamp, what all-colour LED on the market used at present does
Method is the anode by three chips as above while being connected on the same power supply, in order to look after the big VF voltages of blue lamp, green light, institute
It necessarily is greater than 3.3V with supply voltage, can cause to waste a large amount of energy on red light in this way, LED is caused to overheat, reduces reliability,
Shorten the service life, also not energy-efficient environmental protection.So the voltage for how balancing three chips is also a very valuable project.
Invention content
Goal of the invention：The purpose of this utility model is that in view of the deficiencies of the prior art, providing a kind of five foot all-colour LEDs envelope
Assembling structure.
Technical solution：In order to reach foregoing invention purpose, what the utility model was specifically performed by：A kind of five feet are complete
Color LED encapsulation structure, including Ji Dao, the peripheries Ji Dao are equipped with 5 pins being connected therewith by holder, are respectively in pin
Power cord, red light power cord, Data In-Line, DOL Data Output Line and ground wire；Red LED chip, green is respectively equipped with inside base island
Light LED chip, blue-light LED chip and driving chip, each chip are fixed on by conducting resinl or insulating cement on Ji Dao, red-light LED
Chip, green LED chip, blue-light LED chip are electrically connected by conducting wire and driving chip again；The driving chip passes through conducting wire
It is connect with Ji Dao.
Wherein, the driving chip die bond is on Ji Dao.
Wherein, the red LED chip, green LED chip, blue-light LED chip die bond are on Ji Dao.
Wherein, the driving chip controls three LED chips to control the brightness of lamp bead by conducting wire.
Wherein, the red LED chip individually enters voltage control, and blue-light LED chip and green LED chip individually enter
Voltage.
Wherein, the driving chip determines the brightness of LED lamp bead by the pulsewidth width of input data.
Red LED chip positive pole individually connects electricity, blue-light LED chip and green LED chip power supply in the utility model
Anode individually connects electricity, while the three chips other ends are connect by conducting wire with driving chip.Driving chip is distinguished by conducting wire again
It is connected in power pin, data in pin, data out pin；After power input foot powers on, data input pin is again
The control signal of distinct pulse widths is inputted, driving chip receives the signal and then control LED chip is sent out different light,
To achieve the purpose that control lamp color, while data-signal is passed through data output pin output signal, conduction by driving chip again
To next lamp bead.
Advantageous effect：The utility model compared with traditional technology, can simultaneously by red LED chip, green LED chip,
Blue-light LED chip, four chips of driving chip integrate, and to allow the smaller space of full-color LED lamp, reach more
Abundant color.
