The specific embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only shows the formation relevant with the present invention.
Shown in Fig. 1-2, a kind of toilet of high efficiency and heat radiation LED flat lamp, comprise two LED lamp bars that be arranged in parallel, be used for the radiator of LED lamp bar heat radiation and the flat box shaped shell of ccontaining LED lamp bar and radiator, be provided with LGP 2 between the two LED lamp bars, radiator comprises two blocks of first heat sinks 4 of being located at LGP 2 both sides respectively, LED lamp bar comprises pcb board 6 and is located at LED lamp pearl 8, the first heat sinks 4 on the pcb board 6 set gradually corresponding LED lamp bar towards a side of LGP 2 pcb board 6 and LED lamp pearl 8.One side of first heat sink, 4 face away from light guide 2 is provided with polylith fin 12, and the outer rim of fin 12 is arranged in arc 14 at first heat sink 4.
Concrete, housing comprises the light diffusing sheet 16 of being located at LGP 2 fronts and is located at reflectance coating 13 and the backboard 18 at LGP 2 back sides successively, also comprises the L-shaped L shaped connecting plate 22 in two cross sections that connects backboard 18 and light diffusing sheet 16 respectively.Backboard 18, light diffusing sheet 16 and L shaped connecting plate 22 are enclosed the cylindrical shell of both ends open, and two openends of cylindrical shell seal respectively with two blocks of side plates (not shown).The surface of preferred light diffuser plate 16 flushes with L shaped connecting plate 22 respective side surface, can play the effect that prevents dirt accumulation, especially is fit to the toilet and uses.
Radiator comprises that also second heat sink, 24, the second heat sinks 24 that arrange, are located at LGP 2 back sides perpendicular to two blocks of first heat sinks 4 are located at backboard 18 inboards.First heat sink 4 is close to pcb board 6 and is arranged, and heat transfer area is big, bears main heat radiation work, and LED lamp pearl 8 is had electromagnetic shielding action, and second heat sink 24 also contacts with pcb board 6, but heat transfer area is less relatively, bears auxiliary heat dissipation work.
Preferred first heat sink 4 is provided with five fin 12.The angle on the fin 12 at first heat sink, 4 middle parts and first heat sink, 4 planes is 90 °, and to the end, the angle α on fin 12 and first heat sink, 4 planes reduces gradually by first heat sink, 4 middle parts.Make the diverse location of 12 edges of adjacent fin vertical first heat sink 4 directions have different distances, the heat that further produces different spaces transmits difference, strengthens and flows and heat radiation.For example first heat sink, 4 middle parts arrange a fin 12, and two fin 12 are set up at two ends separately, and away from fin 12 directions of centre, the angle α on two fin 12 and first fin, 12 planes is respectively 70 °, 45 °.Further preferred, by first heat sink, 4 middle parts to the end, reducing gradually apart from d of adjacent two fin 12 and first heat sink 4 junctions, increase the heat-dissipating space of the bigger fin 12 of middle part area of dissipation, the corresponding heat-dissipating space that reduces the less fin of two ends area of dissipation 12 rationally utilizes the space.
Preferably, first heat sink 4 vertically is provided with and LED lamp pearl 8 heating column 26 one to one towards a side of LGP 2, and heating column 26 passes pcb board 6 and directly contacts with corresponding LED lamp pearl 8.Save the pcb board 6 as the intermediate transfer medium, improved rate of heat dispation greatly.Further preferred, be provided with through hole 28 in the position that correspondence arranges LED lamp pearl 8 on the pcb board 6, through hole 28 sectional dimensions are less than LED lamp pearl 8 sectional dimensions, and through hole 28 can make heating column 26 pass through.So every pcb board 6 need not to be divided into a plurality of parts and reserves passing through of passage assurance heating column 26, but can keep as a whole, only by being set, through hole 28 fixes LED lamp pearl 8, no matter be at pcb board 6 LED lamp pearls 8 to be installed, still PCB be installed on first heat sink 4 all convenient and high accuracy.For example can avoid a plurality of parts to be spliced into the trueness error of pcb board 6, avoid a LED lamp pearl 8 to be connected across installation difficulty and low precision on the pcb board 6 of at least two divisions.Concrete, LED lamp pearl 8 is fixed on through hole 28 peripheries by its edge, and the heating column 26 of first heat sink 4 passes through hole 28 and directly conflicts on the LED of correspondence lamp pearl 8.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine technical scope according to the claim scope.
