Abstract
The invention discloses a film-pasted COB light source comprising a substrate. A positive electrode, a negative electrode and LEDs are arranged on the substrate. The substrate is provided with an enclosing dam surrounding the LEDs. The enclosing dam is provided with a transparent silica gel layer covering the LEDs. The surface of the transparent silica gel layer is covered by a fluorescent film layer which is formed by uniform mixing of phosphor and silica gel through baking and solidification. According to the film-pasted COB light source, crystal solidification and wire welding are performed on the substrate and then one transparent silica gel layer is sealed firstly, and color of the product is adjusted via additional arrangement of one fluorescent film layer on the transparent silica gel layer, wherein manufacturing of the fluorescent film layer is that the fluorescent film layer is formed by uniform mixing of phosphor and silica gel according to a certain proportion through baking and solidification, and the thickness and the shape of the fluorescent film layer can be determined according to the required color and the product shape.
Description
Technical field
The present invention relates to a kind of pad pasting COB light source, particularly relate to one can on substrate first front cover layer transparent silicon glue-line after die bond, bonding wire, by adding the pad pasting COB light source that the color of one deck phosphor film layer to product adjusts on transparent silicon glue-line again.
Background technology
The flow process of conventional COB is: die bond → bonding wire → glue → light splitting.Wherein need to carry out proportioning debugging before a glue, after parameters is correct, joins glue, some glue again.May need again to debug proportioning due to the change of fluorescent material batch in pilot process, because proportioning debugging can waste a large amount of time in whole process, production efficiency is not high.
Summary of the invention
The present invention is the defect in order to overcome prior art, object is to provide a kind of pad pasting COB light source, this pad pasting COB light source can on substrate first front cover layer transparent silicon glue-line after die bond, bonding wire, adjust by adding the color of one deck phosphor film layer to product on transparent silicon glue-line again, wherein the making of phosphor film layer toasts coagulation forming with after fluorescent material and silica gel by a certain percentage Homogeneous phase mixing, and its thickness and shape determine according to required color and shape of product.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pad pasting COB light source, comprise substrate, positive pole, negative pole and LED is provided with in substrate, substrate is provided with the box dam surrounding LED, box dam is provided with the transparent silicon glue-line covering LED, the surface coverage of transparent silicon glue-line has one deck phosphor film layer, and phosphor film layer toasts coagulation forming after adopting fluorescent material and silica gel Homogeneous phase mixing.
Further, described box dam is circular, and transparent silicon glue-line and phosphor film layer are semiarc shape shape.
In sum, pad pasting COB light source of the present invention avoids conventional production procedure and can waste the more time because of debugging proportioning; When this pad pasting COB light source is produced, just can be mass-produced phosphor film layer after the thickness determining fluorescent film proportioning used and film, later production only need add one deck phosphor film layer on transparent silicon glue-line, its process is simple, strong operability and can save the plenty of time, and the COB colour consistency to produce by this scheme is good, color can convert at any time on demand, and brightness also obtains certain raising.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of pad pasting COB light source of the embodiment of the present invention 1.
