The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, water proof type LED flat lamp for a kind of toilet of good heat dissipation, comprise two LED lamp bars that be arranged in parallel, for the radiator of LED lamp bar heat radiation and the flat box shaped shell of accommodating LED lamp bar and radiator, be provided with LGP 2 between two LED lamp bars, radiator comprises two blocks of first heat sinks 4 of being located at respectively LGP 2 both sides, LED lamp bar comprises pcb board 6 and is located at the LED lamp pearl 8 on pcb board 6, the first heat sink 4 sets gradually pcb board 6 and the LED lamp pearl 8 of corresponding LED lamp bar towards a side of LGP 2, one side of the first heat sink 4 face away from light guide 2 has the arcuate flanks 12 of evagination.
Concrete, housing comprises the light diffusing sheet 14 of being located at LGP 2 fronts and is located at successively reflectance coating 13 and the backboard 16 at LGP 2 back sides, also comprises two L-shaped L shaped connecting plates 18 in cross section that connect respectively light diffusing sheet 14 and backboard 16.Backboard 16, light diffusing sheet 14 and L shaped connecting plate 18 enclose 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 14 flushes with L shaped connecting plate 18 respective side surface, can play the effect that prevents dirt accumulation, especially is applicable to toilet and uses.
Radiator also comprises that the second heat sink 22, the second heat sinks 22 that arrange, are located at LGP 2 back sides perpendicular to two blocks of first heat sinks 4 are located at backboard 16 inboards.14, two blocks of first heat sink 4, the second heat sinks 22 of light diffusing sheet and LGP 2 enclose the first cavity 24.L shaped connecting plate 18, the first heat sink 4 and the second heat sink 22 enclose respectively the second cavity 26 at the flat lamp two ends.The first heat sink 4 is close to pcb board 6 and is arranged, heat transfer area is large, bear main heat radiation work, and LED lamp pearl 8 is had to electromagnetic shielding action, though the second heat sink 22 is the heat transfer area less with the contact area of pcb board 6, but the area of dissipation of the second heat sink 22 is large, bear auxiliary heat dissipation work.
Preferably, along the optional position of the first heat sink 4 length directions, arcuate flanks 12 has identical cross section camber line, and the cross section camber line is circular arc, increase area of dissipation and the heat dissipation direction of the first heat sink 4, this side view is also easy for processing simultaneously simultaneously.Further the central angle of preferred cross-sections camber line is 20 °-30 °.Keep the increase of certain area of dissipation, guarantee the second certain cavity 26 space sizes simultaneously, the heat of being convenient to distribute from the first heat sink 4 sheds from the second cavity 26.
Preferably the second heat sink 22 is provided with the thermovent 28 that is communicated with the second cavity 26.Form the passage that directly for heat in the second cavity 26, is dissipated to second heat sink 22 outsides.Preferably thermovent 28 is the strip of length along the first heat sink 4 length directions, and the width d of thermovent 28 is greater than the second cavity 26 along 3/5ths of thermovent 28 width d direction full-size b.Because the two ends of the second heat sink 22 directly do not contact with pcb board 6, and the second heat sink 22 middle parts have larger radiating surface, the two ends of the second heat sink 22 are mainly to play the effect be connected and fixed with housing, therefore large as far as possible thermovent 28 width dimensions are set, can not affect the thermolysis of the second heat sink 22, can also strengthen on the first heat sink 4 simultaneously distribute heat outside the second heat sink 22, the even quick circulation of hull outside, and avoid heat accumulation in the second cavity 26.
