The packaged type adopts the encapsulation of COB formula, and whole light zone forms single light source, and same colour nature is better, and the base plate adopts mirror surface aluminium to improve the thermal diffusivity of product greatly, mirror surface aluminium reflectivity is greater than 98%, and the optical excitation with the wafer that can be better is come out, during the production operation, the wafer passes through the wafer fixing glue snap -on on the aluminum product, and production efficiency is high, practices thrift the cost. Adopt the flip chip, high luminous efficacy, low thermal resistance, antistatic effect are stronger, and when guaranteeing properties of product, very big degree has improved the life and the reliability of product.
Description
Technical field
The utility model relates to a kind of mirror-surface aluminum base board fluorescent tube, belongs to fluorescent tube technical field.
Background technology
LED fluorescent lamp tube can become one of LED lamp entering indoor the earliest, and this and itself are advantageously inseparable.Its relative fluorescence fluorescent tube has a lot of advantages, and these advantages sum up and are: luminous efficiency is high, energy-saving and environmental protection, life-span are long, not containing ultraviolet, radiationless, starting resistor is low, and safety is without dangerous and stable performance etc.
LED fluorescent lamp tube is the LED electrical light source of a comprehensive application, the control circui design of its good cooling mechanism and uniqueness, not only ensure that the useful life of product, and really reach energy-efficient, its power saving comparatively fluorescent tube can reach more than 60%, high brightness, high-color rendering, does not need to use ballast or starter, without stroboscopic, service time is greater than 50000H, is state-of-the art room lighting product.
Current industry technology main flow is, classifies, can be divided into according to the surface structure of fluorescent tube: " transparent type " and " vaporific type "; According to LED light source classification of type, can be divided into: " plug-in type " and " patch-type "; But above-mentioned fluorescent tube processing disadvantages is:
1. a fluorescent tube needs to use plurality of LEDs finished product light source, when adopting " plug-in type " and " patch-type " light source, because light source self just exists certain color distortion, after plurality of LEDs finished product string of light is linked togather and makes fluorescent tube, even if we are regulated by lampshade, also still can feel that color is inconsistent;
2. current fluorescent tube on the market, substrate is FR4 plate or conventional aluminium substrate, its conductive coefficient is respectively: 1W/mk, 1.5W/mk and 2W/mk, reflectivity is about 80%, all there are some bottlenecks in this two substrate, and then make whole fluorescent tube there is the limitation of some in heat conduction and reflectivity;
3. traditional GaN wafer encapsulation, the electrode due to wafer surface has tied up the area of luminous zone, thus affects wafer luminous efficiency, causes fluorescent tube overall performance to have much room for improvement;
Mirror-surface aluminum base board, is directly made in circuit on substrate, circuit surface pressing insulating barrier, the attached element functional areas of surface of insulating layer, flip chip is directly solid in functional areas, fixedly go out the face shaping of required finished product before encapsulation with box dam glue, then in shaping box dam glue region, put fluorescent glue.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of mirror-surface aluminum base board fluorescent tube.
The utility model mirror-surface aluminum base board fluorescent tube, it comprises mirror-surface aluminum base board 1, wafer 2, die bond glue-line 3, insulating barrier 4, line layer 5, box dam glue 6 and fluorescent glue 7, the upper surface of mirror-surface aluminum base board 1 is provided with several wafer 2 by die bond glue-line 3 bonding, and mirror-surface aluminum base board 1 is made with line layer 5, the surperficial pressing insulating barrier 4 of line layer 5, the surrounding point of mirror-surface aluminum base board 1 has box dam glue 6, puts fluorescent glue 7 in shaping box dam glue 6 region.
As preferably, described wafer 2 is flip chip, and luminous efficiency is high, antistatic effect is stronger.
The beneficial effects of the utility model: 1. packaged type adopts the encapsulation of COB formula, and whole luminous zone forms single light source, and colour consistency is better;
2. substrate adopts specular aluminium, and its feature is: thermoelectricity is separated.Specular aluminium conductive coefficient 137W/mk, than FR4 plate or conventional aluminium substrate high by 98%, substantially increase the thermal diffusivity of product; Its two: specular aluminium reflectivity is greater than 98%, can better by the optical excitation of wafer out; Its three: during production operation, wafer is directly fixed on aluminium by crystal-bonding adhesive, and production efficiency is high, cost-saving.
3. adopt flip chip, high-luminous-efficiency, low thermal resistance, antistatic effect are stronger, and while guarantee properties of product, high degree improves useful life and the reliability of product.
