The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Below in conjunction with concrete accompanying drawing, the realization of the present embodiment is described in detail.
As depicted in figs. 1 and 2, LED lamp bar fixed structure comprises bracket base 13, a plurality of LED lamp bar 12 and filament support 11, is vertically provided with the support column 131 that can settle for filament support 11 on bracket base 13.Filament support 11 is metalwork, is arranged on support column 131, comprises a plurality of lower carriages 112 and a plurality of upper bracket 111.Lower carriage 112 is fixed on support column 131 lower ends, comprise conducting rod 1121 and Duo Gen lower support bar 112, conducting rod 1121 is connected and fixed and lower support bar 112 lower ends, can electricity be imported from the external world to lower carriage 112, lower support bar 112 can be fixed LED lamp bar 12 lower ends, because lower carriage 112 is metalwork, so can electricity be imported to LED lamp bar 12 lower ends by lower support bar 112.Upper bracket 111 is fixed on support column 131 upper ends, also comprises many upper support bars 1112, upper end that can fixed L ED lamp bar 12.The end bending of lower support bar 112 and upper support bar 1112 is snap fit, snap fit has the width over LED lamp bar thickness, and 11 of filament supports are as metalwork, there is certain elasticity and plasticity, LED lamp bar 12 two ends snap in snap fit, and clutch snap fit, can complete with lower support bar 112, upper support bar 1112 and fix.
Because filament support 11 is metalwork, taken into account electric conductivity and plasticity simultaneously, LED lamp bar 12 two ends snap in after snap fit, its plastic deformation can be realized snap fit compression fixing.LED lamp bar 12 can also be switched to power supply by filament support 11.The fixing mode of this snap fit has substituted butt-joint fixation of the prior art, and its advantage of bringing comprises:
1. handling ease, only needs to insert to compress operation, does not need complicated welding equipment, and production efficiency is higher;
2. yields is high, because clamping process is reversible, if positional fault can directly take off and reinstall, and can not occur to locate mistake in butt-joint, does not directly cause irreversible welding unsuccessfully, occurs the problem of defective products, has also indirectly reduced generation cost;
3. little on part impact, do not use after welding, in Assembly of the parts process, without standing high temperature, also there will not be the impact of Yin Gaowen on part, because LED lamp bar 12 relies on LED chip integrated on substrate luminous, substrate need to adopt special anti-high temperature material, and for fear of LED chip high temperature, damage, need to strengthen the distance of LED chip and weld part, cause can be integrated LED chip quantity reduce, the last intensity of illumination that directly affects, and after adopting snap fit, these problems can be avoided.
The quantity of lower carriage 112 can have a plurality of, such as two, four, six etc., in the present embodiment as shown in Figure 2, lower carriage 112 quantity are two, each lower carriage 112 comprises that bullion sheet relatively bends and forms two lower support bars 112, is connected with the both positive and negative polarity that conducting rod 1121, two conducting rod 1121 other ends are electrically connected on respectively extraneous power supply on this strip metal sheet, lower support bar 112 quantity that each lower carriage 112 is provided with are also two, can altogether fix four LED lamp bars 12.Also can adopt in actual applications the lower carriage 112 of other quantity.
Corresponding with lower carriage 112 quantity, upper support bar 1112 quantity are four, as shown in Figure 2, each upper support frame 111 is relatively bent and forms by bullion sheet, and two ends bend out two upper support bar 1112, two upper support frame 111 bending places and are embedded in support column 131, and arrange dorsad, overbending direction is contrary.Each upper support bar 1112 both can play fixation, one end of LED lamp bar 12 can be communicated with again.
It should be noted that, in actual installation, because support column 131 is insulating part, and upper bracket 111 and lower carriage 112 are separate, LED lamp bar 12 upper ends are difficult to directly access in the loop of lower carriage 112 formation, so each upper bracket 111 need to be connected in to two LED lamp bar 12 upper ends on different lower support bars 112, i.e. dislocation arranges to guarantee to form series relationship, make each LED lamp bar 12 can place in circuit in.
LED lamp bar 12 comprises ceramic substrate and be packaged in the LED chip on ceramic substrate, and ceramic two ends are provided with contact, and contact is electrically connected on LED chip, is convenient to LED chip to be communicated to lower support bar 1122, upper support bar 1112.
Support column 131 in the present embodiment is thermoplastic material, the region of interest of lower support bar 1122 and upper support bar 1112 is directly mounted in support column 131 and is fixed when supporting 131 thermoplastics, process at one time, it specifically can adopt the modes such as plastic injection-moulded or glass blowing.
Lower carriage 112 and upper bracket 111 are copper sheet and make, and copper has the advantages such as heat conduction is good, conduction is good, can guarantee 12 normal operations of LED lamp bar.
Outside LED lamp bar 12 and filament support 11, be also covered with globe holder 14, globe holder 14 is Transparent Parts, is convenient to printing opacity and bag protects internal structure.
As shown in Figure 1, the present embodiment also provides LED bulb lamp 1, comprises aforesaid LED lamp bar fixed structure, lamp holder and globe holder 14, bracket base 13 is arranged on lamp holder, conducting rod 1121 is electrically connected on lamp holder, and globe holder 14 is located at outside the structures such as LED, is connected in lamp holder.Lamp holder can screw in or be pressed in extraneous lamp socket, plays the effect of introducing power supply and fixed L ED bulb lamp 1 simultaneously, and itself and globe holder are prior art, and basal body structure does not repeat.
LED bulb lamp 1 in the present embodiment, its LED lamp bar 12 connection procedures are simple, are not prone to waste product in production, and integral production cost is low.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
