Abstract
A light-emitting diode (LED) backlight for a three-phase meter comprises a main body, an edge covering film, LED light sources, a printed circuit board (PCB) and an acrylonitrile butadiene styrene copolymer (ABS) support. The edge covering film is adhered to the upper side of the main body which is fixed on the ABS support, the LED light sources and the PCB which are welded are fixed on one side of the main body, and the main body is formed by adhering a diffusion film, a light guide board and a reflecting film. The LED backlight for the three-phase meter has the advantages that the ABS support is additionally arranged to enable the product to achieve modular installation, and the installation procedure is concise; four guide pins are arranged on the PCB to enable the power supply of the backlight to be stable; three LED light sources are arranged to enable the lighting effect of the LED backlight to be good; and six through holes arranged on one side of the ABS support serve as positioning holes of LED straw hat lamps and infrared emitting diodes so that five positioning columns on the meter and a circuit board are saved, and the structure of the product is simple.
Description
Technical field
The utility model relates to a kind of LED-backlit source that is used for the three-phase table, relates in particular to a kind of LED-backlit source that is used for the three-phase table of light source field.
Background technology
Nowadays, what adopted in most LED-backlit source all is the structural design of LGP one, satisfies the lighting requirement of most industries to the liquid crystal display reading basically at present.At present, the overall technology transformation is done over against national electric instrument by State Grid Corporation of China, is changed into advanced person's electronic watch or more advanced carrier wave meter by mechanical type table the earliest.The simple structural design in tradition LED-backlit source can not satisfy national grid installed and practiced thrift cost to module requirement.The plug-in unit led light source is adopted in most LED-backlit source, and the space hold of plug-in unit is too many, causes small product size bigger.
The utility model content
In order to address the above problem, the utility model is intended to invent the LED-backlit source that is used for the three-phase table that cost was installed and practiced thrift to a kind of ability modularization.
A kind of LED-backlit source that is used for the three-phase table; Comprise main body, bound edge film, led light source, PCB wiring board and ABS support; Described main body upside is stained with the bound edge film, is fixed with main body on the ABS support, and main body one side is fixed with led light source and PCB wiring board; Led light source and the welding of PCB wiring board, described main body are adhered to by diffusion barrier, LGP and reflectance coating and form.
Preferably, described ABS support one side is provided with some through holes.
Preferably, described through hole is 6.
Preferably, described ABS support is provided with 4 reference columns that are used for fixing the PCB wiring board.
Preferably, described PCB wiring board is provided with 4 guide pins.
Preferably, described led light source is 3.
Preferably, described main body is a rectangle.
Preferably, said rectangular length is 85-100mm, and wide is 45-60mm.
A kind of beneficial effect that is used for the LED-backlit source of three-phase table of the utility model is:
1. increased the ABS support, product can modularization be installed, installation procedure is more succinct;
2. the PCB wiring board is provided with 4 guide pins, makes the light source power supply of backlight more stable;
3. led light source is made as 3, makes LED-backlit source lighting effect better;
4. the ABS support one side locating hole that to be provided with six through holes be LED straw hat lamp and infrared-emitting diode has been practiced thrift five reference columns and wiring board on the ammeter, makes the structure of product more simple, and has simplified installation procedure.
