Technical field

The utility model relates to flexible light band fields, and in particular to a kind of flexible light band structure.

Background technique

One kind is electric light source (small tungsten wire lamp bead or LED light source) and flexible plastic cement or silica gel through soft made of special process Property linear modulation band has nearly production in 30 years and applicating history.This light bar due to its softness is plastic, can cut out, mix it is suitable Accessory, it may be convenient to use and moulding, make such lamp decoration be widely used in advertisement, city lighting illumination, commercially shine In bright.

The length of the integrated single work of flexible light band, we always wish that the longer the better, very convenient using meeting in this way, but Due to the presence of line loss, with the increase of length, head and the tail pressure difference increases, and causes the brightness at light bar head and the tail inconsistent, so that Limited length is cascaded, using effect is influenced.Currently, being typically only 5--10 using the cascade length of the flexible light band of DC24V power supply Rice, and the cascade length of the flexible light band of high pressure (AC220) power supply is used to be typically only 50--100 meters, therefore, it is necessary to upper The deficiency stated is improved.

Utility model content

In order to improve the above deficiency, the utility model provides a kind of flexible light band structure that can extend cascade length.This reality Be achieved through the following technical solutions with novel: a kind of flexible light band structure, including shell, the shell is interior to be equipped with flexible circuit board And LED light, the LED light are set on the flexible circuit board, and the first sheet metal and the second sheet metal are additionally provided in the shell, First, second sheet metal is in band-like, and is laid at the adjacent flexible circuit board along the length direction of the shell, In, it insulate between first, second sheet metal, and first sheet metal and the exposed cathode circuit of the flexible circuit board Adjacent, second sheet metal and the exposed cathode traces of the flexible circuit board are adjacent.

Preferably, it is arranged in parallel between first, second sheet metal, and is equipped with the knot for barrier insulation therebetween Structure.

Preferably, clip slot structure, first, second sheet metal are equipped with along the length direction of the shell in the shell It is set at the clip slot structure with the flexible circuit board.

Preferably, the clip slot structure is formed by the wall portion of the shell.

Preferably, first, second sheet metal is copper sheet.

The utility model increases the sectional area of main traverse line, reduces impedance, reduce line by the setting of sheet metal Damage, keeps flexible light band cascade longer, while can also protect flexible circuit board, prevent its fracture.

Detailed description of the invention

The utility model is described in further detail in the following with reference to the drawings and specific embodiments.

Fig. 1 is the schematic cross-sectional view of the utility model embodiment；

Fig. 2 is the explosive view of the utility model embodiment.

Corresponding as follows, the upper housing part 1 of each label, LED light 21, flexible circuit board 22, the first lower housing part 31, the second lower casing in figure Portion 32, the first copper sheet 41, the second copper sheet 42, barrier insulating part 5.

Specific embodiment

With reference to the accompanying drawing and the utility model is further described in embodiment:

As an example, the flexible light band structure of the present embodiment, as illustrated in fig. 1 and 2, including it is shell, LED light 21, soft Property wiring board 22, the first copper sheet 41 and the second copper sheet 42.

Above-mentioned shell includes upper housing part 1, the first lower housing part 31, the second lower housing part 32 and barrier insulating part 5, wherein first The structure of lower housing part 31 and the second lower housing part 32 bilateral symmetry, and it is equipped with the clip slot structure formed by its wall portion, the first lower casing The material of portion 31 and the second lower housing part 32 is non-transparent material, and the material of upper housing part 1 and barrier insulating part 5 is light transmission material.

LED light 21 is located in flexible circuit board 22, and in flexible circuit board 22, the circuit connecting with 21 anode of LED light is Cathode circuit, connecting circuit with 21 cathode of LED light is cathode traces, and above-mentioned cathode circuit and cathode traces are in flexible circuit board It is exposed at 22 lower part.

First copper sheet 41 and the second copper sheet 42 are in band-like.

When specific assembling, along the length direction of above-mentioned shell, the first copper sheet 41 is located to the clip slot knot of the first lower housing part 31 At structure, the second copper sheet 42 is located at the clip slot structure of the second lower housing part 32, by barrier insulating part 5 and the first lower housing part 31, Two lower housing part 32 connection (can be clamping, can also bond), is laid in first for the flexible circuit board 22 for being welded with LED light 21 At the clip slot structure of lower housing part 31 and the second lower housing part 32, so that the first copper sheet 41 and the exposed cathode circuit of flexible circuit board 22 Adjacent, the second copper sheet 42 and the exposed cathode traces of flexible circuit board 22 are adjacent, then by upper housing part 1 and the first lower housing part 31, Second lower housing part 32 connection (can be clamping, can also bond).After being completed, LED light 21, flexible circuit board 22, first Copper sheet 41 and the second copper sheet 42 are located at the inside of shell, parallel between the first copper sheet 41 and the second copper sheet 42.

Above-mentioned barrier insulating part 5 can play, and the first copper sheet 41 is isolated with the second copper sheet 42, is limited to it, and makes its it Between the effects of insulating.In the first copper sheet 41 and the second copper sheet 42 that 22 bottom of flexible circuit board is laid with, it is leading that increase can be played The sectional area of line lowers impedance, reduces line loss, realizes the cascade longer effect of flexible light band, can also play to flexible circuitry Plate 22 is protected from the effect of its fracture.

It should be understood that for those of ordinary skills, it can be modified or changed according to the above description, And all these modifications and variations all should belong to the protection scope of the appended claims for the utility model.

Illustrative description has been carried out to the utility model patent above, it is clear that the realization of the utility model patent not by The limitation of aforesaid way, if the method concept of the utility model patent and the various improvement of technical solution progress are used, or It is not improved that the conception and technical scheme of the utility model patent are directly applied into other occasions, in the utility model In protection scope.
