Description
Technical field
The present invention relates to a kind of mirror-surface aluminum base board fluorescent tube, belong to fluorescent tube technical field.
Background technology
LED fluorescent lamp tube can become one of LED lamp getting in earliest, and this is advantageously inseparable with itself.Have the advantages that a lot for its relative fluorescence fluorescent tube, these advantages sum up and are：Luminous efficiency height, energy-saving and environmental protection, life-span length, do not contain ultraviolet, radiationless, to start voltage low, safety is no dangerous and stable performance etc..
LED fluorescent lamp tube is the LED electric light source of a comprehensive application, the circuit control design case of its good cooling mechanism and uniqueness, not only ensure that the service life of product, and be really achieved energy-efficient, up to more than 60% for its power saving relatively fluorescent tube, high brightness, high-color rendering is it is not necessary to use ballast or starter, no stroboscopic, use time is more than 50000H, is state-of-the art room lighting product.
Industry technology main flow is at present, according to the surface structure classification of fluorescent tube, can be divided into:" transparent type " and " vaporific type "；According to type of LED light source classification, can be divided into:" plug-in type " and " patch-type "；However, above-mentioned fluorescent tube processing disadvantages are：
1. a fluorescent tube needs using plurality of LEDs finished product light source, during using " plug-in type " and " patch-type " light source, because light source itself there is certain color distortion, plurality of LEDs finished product light source is cascaded after making fluorescent tube, even if we are adjusted by lampshade, also still can feel that color is inconsistent；
2. current fluorescent tube on the market, substrate is FR4 plate or common aluminium base, and its heat conductivity is respectively：1W/mk, 1.5W/mk and 2W/mk, reflectance is about 80%, and this two substrate all has some bottlenecks in terms of heat conduction and reflectance, and then makes whole fluorescent tube there is the limitation of some；
3. traditional GaN wafer encapsulation, because the electrode of wafer surface has tied up the area of luminous zone, thus affecting chip luminous efficiency, causes fluorescent tube overall performance to have much room for improvement；
Mirror-surface aluminum base board, circuit is directly made on substrate, and circuit surface presses insulating barrier, surface of insulating layer attached element functional areas, fix out the face shaping of required finished product by directly solid for the chip of falling stake before encapsulation with box dam glue in functional areas, in the box dam glue region of molding, then put fluorescent glue.
Content of the invention
For the problems referred to above, the technical problem to be solved in the present invention is to provide a kind of mirror-surface aluminum base board fluorescent tube.
Invention mirror aluminium base fluorescent tube, it comprises mirror-surface aluminum base board 1, chip 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 passes through die bond glue-line 3 bonding and is provided with several chips 2, and line layer 5 has been done on mirror-surface aluminum base board 1, line layer 5 surface presses insulating barrier 4, the surrounding point of mirror-surface aluminum base board 1 has box dam glue 6, puts fluorescent glue 7 in box dam glue 6 region of molding.
Preferably, described chip 2 is the chip of falling stake, luminous efficiency is high, antistatic effect is higher.
Beneficial effects of the present invention：1. packaged type adopts COB formula to encapsulate, and whole luminous zone forms single light source, and colour consistency is preferable；
2. substrate adopts specular aluminium, and its feature is:Thermoelectricity separates.Specular aluminium heat conductivity 137W/mk, higher by 98% than FR4 plate or common aluminium base, substantially increase the thermal diffusivity of product；It two：Specular aluminium reflectance is more than 98%, preferably can eject the light of chip；It three：During production operation, chip is directly anchored on aluminium by crystal-bonding adhesive, and production efficiency is high, cost-effective.
3. adopt the chip of falling stake, high-luminous-efficiency, low thermal resistance, antistatic effect are higher, and while ensureing properties of product, high degree improves service life and the reliability of product.
