Detailed description of the invention
Make Zhong mono-step below in conjunction with the drawings and specific embodiments to the present invention to illustrate, can better understand the present invention to make those skilled in the art and can be implemented, Dan Suo Bowl embodiment is not as a limitation of the invention.
The present inventor finds through research, after the LED tower crane lamp of current use uses a period of time, there will be lighting effect to decline, light area disperse, the phenomenon that light is uneven, that light source assembly is heated for a long time and causes luminous flat deformation of cylindrical to cause because the light source assembly of LED tower crane lamp directly uses screw to be fixed on the heat-pipe radiator of tower crane lamp.The research of inventor Zhong mono-step finds light source assembly deformation of cylindrical, the contact area of its not heat-pipe radiator can be caused to reduce, thus have impact on the transmission of light source assembly heat, make LED lamp bead cross cause thermal damage, cause light source assembly to reduce service life.Inventor finds simultaneously, and light source assembly directly uses screw perforation, not only damages the globality of pcb board, makes from screw hole generation seepage, thus the risk damaging light source assembly increases.In addition, when LED tower crane lamp is arranged on tower crane, if driving power is positioned at the top of heat-pipe radiator, also can affects heat-pipe radiator heat and distribute, the radiating efficiency of heat-pipe radiator is reduced.To sum up, inventor, based on found problem and reason thereof, has made the present invention.
LED tower crane lamp as shown in Figure 1, Figure 2 and Figure 3, comprises heat-pipe radiator 1, supporter 2, lampshade 3, light source assembly 4, driving power 5 and reflector 6, the LED lamp bead 8 that light source assembly 4 comprises pcb board 7 and is arranged on pcb board 7; Heat-pipe radiator 1 comprises heat pipe heat radiation portion 10 that substrate 13, not the heat pipe endothermic section 9 of matching in heat pipe endothermic section 9, not heat pipe endothermic section 9 connect and is arranged on the fin 14 in heat pipe heat radiation portion 10; Reflector 6 is made up of cup 11 and retainer ring 12; Heat-pipe radiator 1 and lampshade 3 not supporter 2 are fixed together, the agent structure of composition LED tower crane lamp.Reflector 6 and light source assembly 4 are arranged in lampshade 3.
Particularly, be provided with through hole bottom lampshade 3, heat pipe radiator base plate 13 corresponding site is equipped with blind hole, uses fixture to be fixed on the substrate 13 by lampshade 3.Respectively offer through hole on supporter about 2 both sides, use fixture supporter 2 to be fixed on the two sides of heat-pipe radiator 1.Supporter 2 is also provided with fixture 19 and Contraband shape handle 20, offer axis hole at fixture 19 and Contraband shape handle 20 correspondence position, fixture 19 and Contraband shape handle 20 are pivotally connected.
The present inventor, in order to solve degradation problem under the lighting effect that occurs after LED tower crane lamp uses a period of time, LED tower crane lamp substrate 13 arranges fastener 15, for fixed light source assembly 4.This fastener 15 comprises fixed part and buckling parts, and pcb board 7 is connected between fastener 15 and substrate 13, and fastener fixed part is D1 to reflector centre distance, pcb board outer rim is D2 to reflector centre distance, fastener buckling parts is D3 to reflector centre distance, and D1 is greater than D2, and D2 is greater than D3.Fastener fixed part does not leave appropriate gap between pcb board outer rim, can extend, can not cause pcb board 7 deformation of cylindrical, and affect the illumination effect of light source assembly 4 when pcb board 7 is heated on its not heat-pipe radiator 1 contact surface.
Particularly, reflector retainer ring 12 and fastener 15 fixed part relevant position respectively have some through holes, reflector 6 and fastener 15 are fixed on heat pipe radiator base plate 13 with fixture 18.Simultaneously pcb board 7 is connected between the two by fastener 15 and heat pipe radiator base plate 13, makes heat pipe endothermic section 9 thermo-contact of pcb board 7 not heat-pipe radiator 1.Use fastener 15 pcb board 7 is fixed on heat-pipe radiator 1, make pcb board 7 not heat-pipe radiator 1 contact closely, improve the radiating efficiency of light source assembly 4, and not be used in heat-pipe radiator 1 pcb board 7 do not contact position arranging installing hole.
Reflector 6 and fastener 15 use that identical fixture 18 Zhong is capable to be fixed, and also reduce the distribution on heat pipe radiator base plate 13.Reduce distribution and reduce LED tower crane lamp damages light source assembly 4 because of roof leaking risk in outdoor.Adopt that identical fixture 18 Zhong is capable to be fixed, structure is simple, decreases installation procedure simultaneously.
More tight for making the heat pipe endothermic section 9 of light source assembly 4 not heat-pipe radiator 1 contact, obtain better radiating effect, heat-conducting silicone grease can be aided with on the contact surface of pcb board 7 not heat-pipe radiator 1.
For making light source assembly 4 fixing more firm, can offer through hole in the center of pcb board 7, on heat pipe radiator base plate 13, relevant position arranges blind hole, uses fixture 17 to be fixed on the substrate 13 by light source assembly 4.Be fixed on the center of pcb board 7, when pcb board 7 is heated, middle part can not deformation of cylindrical, causes lighting effect to reduce, nor can affect to extend when pcb board 7 is heated and cooling time shrink.
As one of specific embodiment, fastener 15 can be arranged to strip fastener, than the shape of fastener 15 as shown in Figure 3.Fastener 15 can rotate to an angle around fixing point, makes light source assembly 4 installation and removal convenient.
More specifically, the buckling parts outer rim of described fastener 15 can be arranged to arc, than the shape of fastener 15 as shown in Figure 4, arranges the contact area adding fastener 15 not pcb board 7 like this, thus ensures the fixed effect of light source assembly 4.
As another specific embodiment, fastener 15 can be arranged to circular arc fastener, than the shape of fastener 15 as shown in Figure 5.
More specifically, the fixed part of fastener 15 is not provided with connecting portion between buckling parts.The connecting portion of fastener can be arranged to ridge-shaped, than shape as shown in Figure 6, or the connecting portion of fastener is arranged to Contraband shape, than shape as shown in Figure 7.For making fastener 15, there is better screen resilience, interference fit can be adopted between fastener 15 and pcb board 7 to overlap, make light source assembly 4 not heat-pipe radiator 1 combine more tight, and effectively to stop when LED tower crane lamp is arranged on tower crane, the whereabouts trend of light source assembly 4.Fastener 15 can also be arranged to the shape that other can obtain effect same.
The present embodiment provides LED tower crane lamp, and heat-pipe radiator 1 is provided with lampshade 3 side and is provided with power shelf 16, such as power shelf 16 can be arranged on the substrate 13 of lampshade 3 two opposite sides, for placing driving power 5.
