Description
Technical field
The present invention relates to a kind of insulation systems of non-isolated driving lamps and lanterns, belong to energy conservation and environmental protection electronic technology field.
Background technology
In LED illumination industry, LED drive power is that power supply supply is converted to specific voltage and current to drive LED to send out
The power supply changeover device of light, it seems unremarkable in the design of entire illuminating product, but but incomparable crucial.Comply with the need in market
It wants, reduces cost, raising efficiency and reliability has become the target that each enterprise most asks.Light source of new generation is used as to this LED,
Its plasticity on light source provides the thinking of development of differentiation for numerous LED manufacturers.
At present general LED illumination in the market, there are isolated form driving powers and non-isolation type power supply（Including linear drive
It is dynamic）Point.Isolated power supply is due to band isolating transformer, it is meant that LED directly can be contacted without electric shock with hand, large quantities of at present
The use of amount is in I classes and II class lamps and lanterns；Non-isolated driving is since LED can not be in direct contact at work, and there is safety
Hidden danger, at present design are only limitted to double insulating products, such as the substitute products of light bulb, will be relatively more with non-isolated, need
Some mechanical insulation is realized by guard shield, current method, which is LED and entire product, can all be sealed in nonconductive plastic material
In, therefore, there is no the danger of any electric shock by end user.
The product for as one end user can use safely, be bound to the reliability for considering insulation with being isolated.As
Complete product, the part that product surface user can touch have to, by isolation, people cannot be allowed to get an electric shock.And it is whole from product
For a system, isolation is inevitable, and the difference position that only setting is isolated is different.Some designers are using the change being isolated
Transformer design, therefore they can simplify heat dissipation and the design of lampshade.If designed with non-isolated driving, in structures such as lamp housings
On just must take into consideration reliable insulating requirements.When producing LED lamp product, enterprise can go to analyze from many aspects, such as cost
With the requirements such as manufacturing process, efficiency and volume.Driving cost with isolating transformer is higher, and LED lamp is allowed to become costly.
To sum up, isolation circuit used at present is complicated, device is more, and cost is higher, less efficient.Be isolated
Circuit relatively, existing non-isolated circuit, though with circuit it is simple, device used is few, small, and cost is relatively low, efficiency compared with
High advantage, but be isolated due to not done with power grid, security presence hidden danger.Therefore seek a kind of using non-isolated driving lamps and lanterns
Insulation is extremely urgent with isolation scheme.
Insulation mainly divides 2 parts to solve with shielding system, drive part and lamp bead plate part.
Existing way is all by insulating trip come so that electrical body and casing insulation, way are united substantially to drive part at present
One；The way of lamp bead part routine be handled by the insulation of aluminum substrate itself, and the insulation of aluminum substrate be by copper foil and
The insulating layer of about 100um between aluminium sheet, but larger security risk is still remained, reason has at 2 points --- and aluminum substrate itself is with after
Phase processes process, as follows：
Reason 1：Referring to Fig.1, the structural schematic diagram of non-isolated driving lamps and lanterns aluminum substrate, point 4 layers of composition, respectively erosion-resisting oil
Ink, copper foil, insulating layer, aluminium sheet.It is only obstructed by the insulating layer of the epoxy resin of one layer of 100um between aluminium sheet and copper foil, ring
Oxygen resin insulating barrier in process of production, may have a vacuum phenomenon, and extremely difficult discovery during the test.
Reason 2：After the aluminum substrate of monoblock transports to processing factory, sawing sheet-nog plate-exposure-development-etching-welding resistance-will also be subjected to
The techniques such as baking sheet-drilling-molding-osp- packagings, in these processes, aluminum substrate is easy to encounter sharp object, asphalt mixtures modified by epoxy resin
The insulating layer of fat is pierced.In addition, during being assembled into lamps and lanterns, first, easily encountering sharp objects；Second, the height of welding
Temperature can make the fragility that epoxy resin insulating layers become, and slightly firmly insulating layer will be made ineffective.
In view of this, the applicant specializes in this, a kind of insulation system of non-isolated driving lamps and lanterns is developed,
Thus this case generates.
