Description
Technical field
The utility model relates to a kind of LED-backlit product-derived technical field, relates in particular to a kind of polychrome district changeable colour LED-backlit product-derived that is provided with a plurality of luminous zones, can sends a plurality of colors.
Background technology
Backlight mainly is comprised of light source, LGP, optical film sheet, plastic frame etc.It is high that backlight has brightness, long, the luminous characteristics such as evenly of life-span.Mainly contain at present tri-kinds of type of backlight of EL, CCFL and LED, according to distribution of light sources position difference, be divided into side-light type and straight-down negative.
Along with the LED module constantly to brighter, gentlier, thinner future development, side-light type CCFL formula backlight becomes the main flow of current backlight development.
The thin amount of electroluminescent (EL) backlight body is light, the light uniformity provided.Its power consumption is very low, and the operating voltage of requirement is 80～100Vac, provides the inverter of operating voltage to be transformed to the input of 5/12/24Vdc to exchange output.But the service life of EL backlight is limited, be 3000～5000 hours the average life under 50% brightness conditions, on higher luminance level, will shorten dramatically service life, therefore, desirable EL back lighting allows output voltage and frequency to increase along with the aging of EL bulb with inverter, thereby extends the Acceptable life of the display of the back lighting light source that adopts EL.
The service life in LED-backlit source is longer than EL, and uses DC voltage, usually is applied to small-sized monochrome display, such as phone, remote controller, micro-wave oven, air-conditioning, instrument and meter, stereo audio equipment etc.But, its brightness at present also deficiency think that large-scale transmissive display provides back side light source.The LED-backlit source is structurally consistent with the CCFL backlight substantially, and wherein main difference is that LED is spot light, and CCFL is line source.
In the LED-backlit source of prior art, backlight can only send a kind of color in same flake products light-emitting zone, and the coloured light therefore sent is single, can not adapt to backlight Diversification development trend, and meet the need of market.
Therefore, need a kind of polychrome district changeable colour LED-backlit product-derived that can in same flake products light-emitting zone, send manifold color-emitting badly.
The utility model content
The purpose of this utility model is to provide a kind of polychrome district changeable colour LED-backlit product-derived that can in same flake products light-emitting zone, send manifold color-emitting.
To achieve these goals, the utility model provides a kind of polychrome district changeable colour LED-backlit product-derived, it comprises: the LED light source of pcb board, LGP, several coloured light, glue frame and diffusion barrier, be provided with at least two described LGPs on described pcb board, the described glue frame of described LED light source that is provided with at least two kinds of coloured light on each described LGP is coated on described LED light source and described LGP, described diffusion barrier is bonded on described glue frame, forms described polychrome district changeable colour LED-backlit product-derived.
The quantity of described LGP is according to the quantity setting of described LED light source, and described LED light source comprises the LED light source of several coloured light, and is arranged on accordingly on described LGP.
Described pcb board is provided with a plurality of for the light-emitting zone of described LGP is installed, and adjacent two described light-emitting zones are provided with line of demarcation.
Described LED light source can be the LED lamp bar of various coloured light.
Compared with prior art, due in the utility model polychrome district changeable colour LED-backlit product-derived, described LED light source can be selected to the described LED light source into several different colours, red LED light source for example, White LED light source, blue led light source etc., and the described LED light source of these different colours is arranged on different described LGPs accordingly, be provided with at least two kinds of described LED light sources on each described LGP, and the size of described LGP can be designed according to client's needs, between adjacent described LGP, line of demarcation is set, while therefore switching on power, can on each LGP, select to allow any described LED light source luminous, therefore described polychrome district changeable colour LED-backlit product-derived can send several different color of light, and not there will be the phenomenon of in the past mutually altering light.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are for explaining embodiment of the present utility model.
The accompanying drawing explanation
The structural representation of an embodiment of the LGP that Fig. 1 is the utility model polychrome district changeable colour LED-backlit product-derived.
The diffusion barrier that Fig. 2 is polychrome district changeable colour LED-backlit product-derived as shown in Figure 1 will be bonded in the schematic diagram of glue frame.
The schematic diagram that Fig. 3 is polychrome district changeable colour LED-backlit product-derived access failure power supply as shown in Figure 1.
Fig. 4 is polychrome district changeable colour LED-backlit product-derived as shown in Figure 1 switches on power after luminous schematic diagram.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, in accompanying drawing, similar element numbers represents similar element.As mentioned above, as Fig. 1, 2, 3, shown in 4, the polychrome district changeable colour LED-backlit product-derived 100 that the utility model provides, it comprises: pcb board 10, three LGP 20a not of uniform size as shown in Figure 1, 20b, 20c, and described LGP is unified to label is 20, the size of described LGP 20 can be designed according to client's needs, and at described LGP 20a, 20b, the described LED light source (not showing on figure) of three kinds of different colours is set on 20c, described LED-backlit product-derived 100 also comprises glue frame 30 and diffusion barrier 40, be provided with at least two kinds of described LED light sources on each described LGP 20, therefore each described LGP 20 can send at least two kinds of coloured light, , and described LED light source and described LGP 20 are coated by described glue frame 30, described diffusion barrier 40 is bonded on described glue frame 30, form described polychrome district changeable colour LED-backlit product-derived 100.
