Description
Technical field
A kind of panel light of sandblasting frame heat dissipation is the utility model is related to, especially one kind can improve panel light heat dissipation effect
Fruit, the outer list processing of wear-resisting and anticorrosion sandblasting, a kind of structure without changing other mounting means, belongs to semiconductor illumination technique neck
Domain.
Background technology
The light source of early stage panel light uses fluorescent tube more, and heat is low, without considering frame heat dissipation problem.
Recent LED panel lamp frame uses extrusion forming, and the product heat dissipation area that this is squeezed out is fairly limited, and
Cutting and welding procedure are employed when carrying out four edges frame combination squarely, and often due to producing when this cutting and welding
High temperature, which can make very thin aluminum alloy frame adjacent locations produce oxidation, to be caused to change colour；When finished product is made in order to cover these discolorations
Method employ spray paint measure to be covered, but paint belongs to nonmetallic, and heat conduction and heat-sinking capability all very poor its are led
Hot coefficient only has 0.8W/M.K or so；Here it is panel light power currently on the market do less, heat dissipation effect is poor, lamp life is short
The reason for；It is known that LED is that To Be Protected from Heat light source, when the junction temperature on LED luminescence chip PN junctions is at 65 DEG C the service life can be up to 100,000
Hour, then often raise 10 DEG C of temperature when the service life will shorten half；So the technical task mainly studied in the world today be as
Limited radiator structure is reduced LED junction temperature and ensures LED lamp service life by what to reach.
The content of the invention
For the utility model in order to overcome drawbacks described above, the purpose is to be that it is in rough surface energy to provide a kind of sandblasting
Increase heat dissipation area, heat dissipation effect can be improved and appearance is beautiful, easy for installation and can realize and can be increased under identical structure situation
Design of Luminaires power again can prolonging service lives of lamps a kind of sandblasting frame heat dissipation panel light.
The utility model to achieve these goals, is achieved by the following technical programs：
A kind of panel light of sandblasting frame heat dissipation, it includes：Frame, LED aluminum base plate, diffuser plate, light guide plate, reflecting paper,
Foam-rubber cushion, backboard；
The panel light is from the back side of lamp body to the structural order that stacks gradually of front：Backboard, foam-rubber cushion, reflecting paper, lead
Tabula rasa, diffuser plate；
The structural plane of installation LED aluminum base plate, the horizontal plane of plate placement lamp diffuser plate accessory and centre are designed with frame
Square hole；
Except the outer surface position of structural plane, the horizontal plane of plate placement lamp diffuser plate accessory and middle square hole on frame
Put region and be provided with sandblasting layer；
It is square on the surface of the sandblasting layer of frame and structural plane, the horizontal plane of plate placement lamp diffuser plate accessory and centre
The outer surface in hole is provided with anticorrosion oxide layer.
Further, fixed screw holes and conducting wire card slot are provided with backboard；
The fixed screw holes are located at the edge of backboard, and the conducting wire card slot is located at the angle end of backboard.
Further, the sandblasting layer is the structure of surface irregularity.
The beneficial effects of the utility model：
The panel light of the utility model is a kind of panel light of sandblasting frame heat dissipation, it can improve heat dissipation effect and appearance drift
It is bright, easy for installation and can realize Design of Luminaires power can be increased under identical structure situation again can prolonging service lives of lamps.

Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
A kind of panel light of sandblasting frame heat dissipation, it includes：Frame 1, LED aluminum base plate 2, diffuser plate 3, light guide plate 4, reflection
Paper 5, foam-rubber cushion 6, backboard 7；
The panel light is from the back side of lamp body to the structural order that stacks gradually of front：Backboard 7, foam-rubber cushion 6, reflecting paper 5,
Light guide plate 4, diffuser plate 3；
Structural plane 1-1, the horizontal plane 1-2 of plate placement lamp diffuser plate accessory of installation LED aluminum base plate are designed with frame 1
With middle square hole 1-3；
Except structural plane 1-1, the horizontal plane 1-2 of plate placement lamp diffuser plate accessory and middle square hole 1-3 on frame 1
Outer surface position region be provided with sandblasting layer；
The surface of the sandblasting layer of frame 1 and structural plane 1-1, plate placement lamp diffuser plate accessory horizontal plane 1-2 and
The outer surface of middle square hole 1-3 is provided with anticorrosion oxide layer.
Fixed screw holes 7-1 and conducting wire card slot 7-2 are provided with backboard 7；
The fixed screw holes 7-1 is located at the edge of backboard 7, and the conducting wire card slot 7-2 is located at the angle end of backboard 7.
The sandblasting layer is the structure of surface irregularity.
Because this type panel light is saves expensive material cost, panel light is with the thickness structure of ultra-thin 8-9mm
Occur, and so thin structure there is heat dissipation area reduction, be in turn mounted at the immobilising interior of closed air, this is just into this
The panel lamp power of type structure is done less, service life not very long technical bottleneck.
Heat-removal modalities have three kinds of modes：Conduction, convection current, radiation；And convection current accounts for the 70% of heat dissipation mainstream, heat loss through conduction accounts for 20%
Ratio；In order to which heat dissipation effect must most preferably increase conduction surface and the conductive-convective space of heat dissipation.
The utility model takes frame except the horizontal plane of the accessories such as installation LED aluminum base plate position, plate placement lamp diffuser plate
Illustrated with blasting treatment is all carried out at middle square hole without other positions outside blasting treatment；Former panel lamp frame
It is the strip smooth surface come out by extrusion die extrusion molding, this patent, which is particularly, carries out product surface the position meeting after blasting treatment
The many intensive rough points of increase, these points can increase the total heat dissipation area and increase appearance wearability of frame, this
A little increased heat dissipation areas are conducive to increase conductive-convective space, then carry out surface oxidation again to carry out frame anticorrosion and outer
Sight is handled, and thermal conductivity factor 0.8W/M.K of the thermal conductivity factor of aluminium oxide between 28-32W/M.K than taking painted surface to handle
It is about four times big.
After frame four edges frame is first assembled integrally by this product installation process, then frame is carried out at sandblasting and oxidation
Reason；It is close to again by product requirement on frame after heat-conducting silica gel sheet is sticked at the LED aluminum base plate back side again, then installation diffusion successively
Plate 3, light guide plate 4, reflecting paper 5, foam-rubber cushion 6, backboard 7, card slot 7-2 conducting wire being caught on backboard, finally squeezes into the back of the body with screw
Screw fixing hole 7-1 on plate.
In addition to the implementation, the utility model can also have other embodiment, all to use equivalent substitution or equivalent change
The technical solution of form is changed, is all fallen within the protection domain of the requires of the utility model.
