Description
Technical field
The utility model belongs to the LED field of illumination lamp technology, particularly relates to a kind of ultra thin LED flat lamp.
Background technology
Ultra thin LED flat lamp on the existing market mainly adopts the mode of four limit aluminum alloy extrusion section bar splicings to assemble, and this mode die cost is lower, dimensional flexibility good, the construction cycle is short, so obtained using widely.But the several problems of this mode ubiquity:
1, rigidity is poor, makes light fixture be easy to torsional deformation, not only causes the change in gap between LED and the LGP easily, influences the light fixture light efficiency, and may cause that damage that light inlet side leakage light, four corner connections seam strengthens light leak, circuit causes the damage of light fixture etc.
2, assembling difficulty is difficult to guarantee dimensional accuracy and the stability of light fixture, and not only production efficiency is had a strong impact on, and is also very big to the influence of quality (comprising the control, light leak in gap between LED and the LGP etc.).
When 3, using for a long time, light fixture is easy to generate distortion, thereby causes the generation of shaded stripe.
4, be difficult to adopt the mode of lifting, because can produce serious deformation, thereby have to adopt extra structure to be strengthened, namely increasing cost has inconvenience, also not attractive in appearance.
5, there is tangible piece in four corners of light fixture, and this has not only caused light fixture to produce the phenomenon of light leak herein, and has influenced the outward appearance of light fixture.
Summary of the invention
The utility model purpose be the defective at prior art provide a kind of rigidity height, good reliability, cost low, not light leak, light efficiency height, light is even, molded dimension is various, easy-to-install thin-type LED light fixture.
The utility model adopts following technical scheme for achieving the above object:
A kind of ultra thin LED flat lamp, comprise the light fixture frame with step that is spliced by aluminum alloy extrusion section bar, with the diffuser plate that sets gradually at step, LGP, reflective membrane, elastic buffer plate and backboard, and the LED lamp bar that is arranged on the LGP side, it is characterized in that: described aluminum alloy extrusion section bar has rectangular through-hole in the cross section, each section bar end face is 45 ° of tangent planes, is spliced into rectangle light fixture frame by the L shaped connector that is arranged in the rectangular through-hole; Described L shaped connector is fastening with screw by screw on the step of the aluminum alloy extrusion section bar back side.
It is further characterized in that: described aluminum alloy extrusion section bar has the multilayer step, and the ground floor step is used for placing diffuser plate, and its height is a little less than the thickness of diffuser plate; Second layer step side is provided with groove, and described LED lamp bar is arranged in the described groove, and described LED lamp bar centre-height is consistent with the light inlet side centre-height of LGP; The 3rd layer of step is used for placing described backboard.
Further: it is characterized in that: described LGP all has the notch cuttype breach on four angles, four shape locating pieces that are complementary are with it respectively placed in the space that forms with light fixture frame corner, make the gap between LGP side incidence surface and the LED lamp bar remain unchanged by locating piece.
Described locating piece top is provided with groove and matches with described backboard be used to pushing down LED lamp bar output line.
Its further feature also is: four fan-shaped triangular steel plates are placed at place, four angles of described backboard, and triangular steel plate is pushed down each following parts by the screw on the step of the aluminum alloy extrusion section bar back side and be fixing; Both sides, the backboard back side have respectively been installed and have been bent into L shaped ear stamping parts, two through holes are arranged on the ear stamping parts minor face, be fixed on the light fixture back side by the screw on the step of the aluminum alloy extrusion section bar back side with screw, the ear stamping parts has the I shape through hole to be used for mounting spring on the long limit.
Above-mentioned diffuser plate can be materials such as PS, PMMA, PC.
Above-mentioned LGP can be materials such as PMMA, PC, and the back side is printed the specified point array and is used for reflection ray, guarantees that the light that side LED sends penetrates from the light-emitting area perpendicular to the lamp bar, and LGP is installed on the diffuser plate back side.
The carbon element carbon steel that above-mentioned L shaped connector is high rigidity is stamped to form.
Above-mentioned locating piece is that the elastic insulating material with certain degree of hardness is made; material can be silica gel, polyurethane, EVA etc.; its distinctive elasticity can be guaranteed after light fixture uses a period of time; the lamp interior temperature raises when causing the LGP volumetric expansion; himself deform to guarantee the invariant position of LGP, protection LED lamp pearl.
Described elastic buffer plate is that high-temperature insulation material cuts and forms, and material can be high temperature resistant hard foam, pearl plate etc.
The carbon element carbon steel stamping parts that described fan-shaped triangular steel plate is high rigidity.
Compared with prior art, the utlity model has following advantage: the utility model rigidity of structure is higher, and better reliability, assembling are simply, production efficiency is high, light leak is few, bright dipping is even.The thin-type LED light fixture is by increasing the connector of inlaying a L type between edge strip, make frame before diffuser plate, LGP and backboard are installed, form a firm frame, under the prerequisite that does not take the lamp interior space, installation steps have been simplified, improve production efficiency, thereby reduced the cost of light fixture; Simultaneously be installed in triangular steel plate on four angles of backboard has improved whole lamp from two aspects rigidity; And use the fastening adjacent edge strip of screw and connector, and can regulate gap between edge strip by adjusting the screw elasticity, can farthest reduce piece.Secondly, the innermost shoulder height in the frame back side that assembly is good is more lower slightly than diffuser plate thickness, and this step has not only been located diffuser plate can effectively prevent the light fixture light leak simultaneously; And the groove of frame medial side face has effectively been located the centre-height of LED on the lamp bar, make that its side incidence surface height with LGP is consistent, the hard locating piece of installing on four angles has guaranteed to have between LED and the LGP light inlet side gap of a stable and consistent, these structural location have guaranteed the relative position of each part of lamp interior, thereby have improved the light efficiency of light fixture; And the groove structure at locating piece top and top cover plate form the space that is slightly less than the output line footpath of sealing, the position of having limited output line, solved light fixture in assembling process owing to output line moves the assembly problem that causes, improved installation effectiveness; At last, be fixed on the ear stamping parts mounting spring at the light fixture back side after the bending after, make light fixture equally to be used for ceiling with Down lamp and inhale the top and install, simplified installation steps and improved installation effectiveness simultaneously, reduced cost.
The utility model has solved the insurmountable a series of problems of common thin-type LED flat lamp, and moulding is changeable, and applicability is stronger, simple installation.To compare light efficiency higher with product of the same type, and light loss is littler, and applicable situation is more extensive.
