Technical field
The present invention relates to light mixing method and the LED component of LED.
Background technology
Because the brightness of LED is high, low in energy consumption, the life-span is long, it is fast to start, luminous efficiency is high, flicker free, to be not easy to produce visual angle tired, LED gradually instead of transmission light fixture.
In LED field, mixed light is wherein one of important research direction.Now, wherein a kind of light mixing method utilizes the different chips of more than three to carry out mixed light, as at application number be 201010289388.3 patent documentation in disclose a kind of light mixing method, this light mixing method is exactly utilize the chip of different colours to carry out mixed light, although this light mixing method can improve brightness, but because the performance of different colours chip is different, requirement, light efficiency performance etc. as light decay performance, electric current all can be different, therefore, the consistency of light decay can be caused to be difficult to control, the consistency of electric current is uncontrollable, and light efficiency is low, and the circuit of control is complicated.
Now, a kind of light mixing method is also had to be utilize to excite RGB mixed fluorescent powder with color chip, this light mixing method, once the ratio-dependent of RGB fluorescent material, then the colour temperature of LED and tone all uncontrollable, and for same chip, when the current value passed into is identical, it excites the efficiency of R, G, B fluorescent material different, thus can affect the light efficiency of LED; In addition, owing to being excited the fluorescent material of mixing by same chip, if regulate the electric current of chip, then whole light-out effect may change.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of LED light mixing method and LED component.
The technical scheme solved the problems of the technologies described above is: a kind of LED light mixing method, provides more than one mixed light unit, and each mixed light unit is made up of the chip of the same race of more than three; Every chips of each mixed light unit encapsulates respectively one-color fluorescence arogel water mixture, wherein, at least three chips encapsulate respectively red fluorescence powder glue mixture, green emitting phosphor glue mixture and blue colour fluorescent powder glue mixture; Mixed light is carried out after the one-color fluorescence arogel water mixture that each chips in each mixed light unit excites correspondence to be encapsulated on chip.
Further, each mixed light unit is made up of three chips of the same race, three chips encapsulate red fluorescence powder glue mixture, green emitting phosphor glue mixture and blue colour fluorescent powder glue mixture respectively, after the one-color fluorescence arogel water mixture that each chips excites correspondence to be encapsulated on chip, blendes together white light
.
A kind of LED component, comprise substrate, substrate is provided with more than one mixed light unit, each mixed light unit is made up of the chip of the same race that more than three are carried out mixed light; Every chips of each mixed light unit encapsulates respectively one-color fluorescence arogel water mixture, wherein, at least three chips encapsulate respectively red fluorescence powder glue mixture, green emitting phosphor glue mixture and blue colour fluorescent powder glue mixture.
Further, each mixed light unit is made up of three chips of the same race, and three chips that finally can blend together white light encapsulate red fluorescence powder glue mixture, green emitting phosphor glue mixture and blue colour fluorescent powder glue mixture respectively.
The invention has the beneficial effects as follows: owing to have employed identical chip, the consistency of performance of chip of the same race is good, therefore, is easily controlled the consistency of light decay by the LED component of this light mixing method and correspondence thereof; Because this light mixing method and LED component excite the fluorescent material of single color then to carry out mixed light by independently chip, therefore, colour temperature and tone can be controlled by controlling independent chip; In addition, by allocating the consumption of the corresponding fluorescent material of each chip, the electric current of every chips can be allowed consistent, thus obtain corresponding light efficiency, therefore, the consistency of electric current is controlled; In the present invention, utilize identical chip, and the corresponding monochromatic fluorescent material of each chip carries out mixed light, relative to prior art, light efficiency can improve 2-4 doubly.In addition, adopt identical chip, can simplified control circuit.
