Description
Technical field
The present invention relates to a kind of high-power LED fluorescent powder apparatus for coating, is a kind of device of realizing implementing high-power LED fluorescent powder coating on-line autocontrol light color specifically.
Background technology
At present, the generation technique of some kinds of LED white lights is arranged in the world, mainstream technology wherein is to excite yellow fluorescent powder to produce white light with blue chip, and this relates to the problem of fluorescent material coating.The coating of fluorescent material is directly connected to the uniformity and the luminous efficiency of the photochromic performance of white light LEDs, photochromic spatial distribution.The proportioning of these performances of product and bare chip parameter, support parameter, phosphor gel, the chromaticity coordinates (x of fluorescent material, y), the graphical coating of phosphor gel amount and phosphor gel is directly related, therefore, in the encapsulation of carrying out great power LED was produced, the device of implementing the high-power LED fluorescent powder coating just seemed very important.Existing in the market high-power LED fluorescent powder apparatus for coating mainly all is a control phosphor gel amount, its fluorescent-powder coating method mainly is divided into two kinds: a kind of is manually quantitatively to put glue by the precise glue dispensing machine by photochromic tester, must add, subtract the glue amount repeatedly for reaching desired parameter.This method is more general, can only control the phosphor gel amount roughly, can not carry out the graphical coating of phosphor gel, therefore, because influencing the phosphor gel amount of the photochromic performance of product is controlled roughly, so the photochromic performance of product is passable, but because the fluorescent material coating is not patterned, crawling is even, formed phosphor powder layer is inhomogeneous, irregular, can not make five faces of chip light emitting wrap up in layer of fluorescent powder equably, the uniformity of phosphor powder layer is directly connected to the uniformity of the spatial distribution of the light that chip sends, so the spatial distribution of the light that chip sends is inhomogeneous, causes the photochromic consistency of product very poor, the irregular light that chip is sent of phosphor powder layer reflects in lens inside, refraction loss has reduced the luminous efficiency of product.In addition, because operation manually, speed is quite slow; A kind of is volume and the shape of measuring reflector on a group or a few pack support by CCD, manually determines the glue amount, utilizes the precise glue dispensing machine to carry out mechanization then and quantitatively puts glue.This mode is quite high to the coherence request of support and chip, and the hypothesis of its work is: the performance parameter of the size of all supports, size and all chips is on all four.This method speed is fast, but the glue amount of fluorescent material coating is impossible in full accordly not to be effectively controlled because of the performance parameter of size, size and all chips of all supports in fact, and this mode is not implemented graphical coating to the coating of phosphor gel yet, the not only photochromic performance of product processed does not include like this, and photochromic spatial distribution is also inhomogeneous.In addition, also has a kind of high-power LED fluorescent powder apparatus for coating on the market, it can implement the graphical coating of high-power LED fluorescent powder glue, but it can not control the glue amount exactly, the photochromic spatial distribution of product processed is even like this, but the photochromic performance of product is bad, causes the photochromic consistency of product poor.There just do not have a kind of high-power LED fluorescent powder apparatus for coating product processed both to satisfy photochromic performance in the market to be good at all, it is uniform to satisfy photochromic spatial distribution again, this has influenced the development of the development of semiconductor lighting, particularly large power white light LED to a certain extent.
