Description

A kind of Foldable LED lamp

Technical field

The utility model relates to the LED field of illuminating lamps, especially a kind of Foldable LED lamp.

Background technology

LED is as a kind of low energy consumption, the luminous lighting product in high brightness and life-span, be widely used in illuminating industry, in use, LED often is processed into the lamp bar of a plurality of LED stripe-arrangement, then is fixed on the accoles such as shelf, because the bent degree of LED lamp bar is limited, if size is larger, bending degree has in limited time must carry out the split manufacturing as required, splices during use again, transportation and installation be relatively inconvenience all, especially large-scale LED lamp owing to need the LED of a plurality of splicings, is not easy packing and transportation very much, and take the storage area, so that large-scale LED lamp often need to carry out packed and transported by being divided into some, then assemble, its process is loaded down with trivial details, and in assembling, causing easily the damage of LED lamp bar, the process of assembling is also comparatively loaded down with trivial details, expends a large amount of manpower and materials.

Existing foldable LED, it is 200920161383.5 Chinese patent application such as application number, a kind of foldable extension LED lamp is disclosed, comprise lamp socket, two or more folding connecting rods, establish the LED transparency window with the LED assembly in each described folding connecting rod phase same side, described LED assembly is arranged in the LED transparency window, connects by rotating shaft between two adjacent folding connecting rods.The weak point of the method is that it mainly adopts bar linkage structure, and structure is comparatively complicated, and is not too convenient when being applied to a plurality of LED combination.Application number is 201020293515.2 Chinese patent application, a kind of Foldable LED display screen is disclosed, comprise that at least one row are equipped with the unit display screen of LED, wherein connect by foldable mechanism between the two neighbouring module unit display screens in the same column unit display screen, described fold mechanism comprises hinge or flexible cable syndeton.When in installation process, the upper end of this LED display is connected elevating mechanism, under the driving of elevating mechanism, the utility model is promoted, then can form a complete giant-screen, under the driving of elevating mechanism, the utility model is descended, then the utility model can be folded up.Greatly reduce volume after the LED display of this structure is folding, be convenient to packing and transportation; Secondly the monoblock giant-screen is made of some the moulding process difficult problems when having avoided volume excessive some module unit display screens.The weak point of the method is that structure is comparatively complicated, and overall weight is larger, is difficult for often assembling.Application number is the Chinese patent application of 201120037299.X, discloses a kind of foldable LED flat lamp, and its structure is comprised of plurality of LEDs light source, PCB substrate lamp bar, aluminium sheet, frame, frosted diffuser, rotatable hinge.Many low-power LED light sources equidistantly are arranged on the PCB substrate lamp bar, the even stationary arrangement of lamp bar is on aluminium sheet, with edge frame made of aluminum profiles fixing and locking aluminium sheet and frosted diffuser, the common single separate component that consists of the LED flat lamp, improve the uniformity and the eye of LED light and can't see light source, thereby connect two independently folding rotating functions of LED flat lamp realization with rotatable hinge again, realize the 360 degree omnidirectionals of LED.The weak point of the method is, adopts and rotates comparatively complexity of this structure of hinge, has improved cost.

The utility model content

Technical problem to be solved in the utility model is a kind of foldable LED lamp, solves existing large LED lamp assembling difficulty, complex structure, the problem of difficult packing and transportation.

The technical solution of the utility model is, a kind of Foldable LED lamp, comprise several lamp bar modules, described lamp bar module comprises base, the LED light emitting diode, described base is provided with circuit board, described LED light emitting diode is fixed on the circuit of circuit board, also be provided with binding post on the described base, described binding post is connected respectively with the both positive and negative polarity wire of described board circuit, be fixed with respectively flexible cable on the described binding post, the conductor of described flexible cable is connected with binding post, interconnects by flexible cable between described some lamp bar modules.

Above-mentioned a kind of Foldable LED lamp, the cross section of described base is U-shaped, the height of described circuit board and LED light emitting diode is lower than the height of base, is positioned at base.

Above-mentioned a kind of Foldable LED lamp, the space between described circuit board and the base is filled with casting glue.

Described flexible cable be for can adopt present published flexible cable structure, covers the structure of sheath outward such as conductor, and conductor adopts the soft copper conductor behind the anneal, and sheath adopts the elastic body jacket of fourth polymers.Owing to this cable particularly soft, anti-bending, steadily do not turn round, can effectively lamp bar module be coupled together each other by this flexible cable, form an integral body, and the length that flexible cable can be set as required matches with the number of lamp bar module.The conductor of flexible cable is connected with binding post, can also become the wire that circuit connects between the lamp bar group mould, in the positive and negative electrode circuit of place in circuit plate and LED light emitting diode, can be in use so that the circuit of a plurality of lamp bar group moulds passes through conductor and the electric power generating composition loop of flexible cable.Like this, be connected the difficulty of wiring when having exempted assembly and disassembly with connection with regard to the assembling that does not need to carry out again in addition wire.

The number setting of binding post can be selected as required, 2 binding posts of both positive and negative polarity generally can be set respectively, when lamp bar module width is long, can increase binding post, as arranging 4,8 binding posts are so that arrange the cable of suitable quantity, effectively connecting lamp bar module prevents the excessive problem that is easy to fracture of cable load-bearing when quantity is very few.Simultaneously the sheath of this flexible cable can also make the cable indoor/outdoor can both adaptive temperature and soda acid oil salt, strengthens reliability, long perfomance life.

By this structure, several lamp bar modules can be set in groups, a plurality of lamp bar modules are linked together, these modules are owing to can fold, and instant packed transportation launches lamp bar module to get final product in use, has also removed the complicated process of assembling from.

The cross section of described base is U-shaped, and the height of described circuit board and LED light emitting diode is lower than the height of base, is positioned at base.Because the height of base is higher than the height of LED light emitting diode; can enclose by three bread of base so that be unlikely to the LED light emitting diode; the structure that one side exceeds forms protection; when lamp bar module of the present utility model is folding; even a plurality of base plates are overlapping; the LED light emitting diode can not collided yet and be damaged, and this structure can make the LED light emitting diode protect by base.

Casting glue is filled in space between circuit board and the base plate, can play guard lamp bar module, plays the effect of waterproof, damping.

Beneficial effect: the utility model can be simplified the connected mode of LED module, and is simple in structure, and assembling is easy, and cost is low, is easy to packing and transportation.
