Description

A kind of LED LGP bulb and preparation method thereof
Technical field
The present invention relates to lighting bulb, especially a kind of LED LGP bulb that is applicable to aspects such as all kinds of illuminations, artistic lighting and decorative lighting and preparation method thereof.
Background technology
The LGP design principle comes from the LCDs of notebook computer.LGP utilizes fluorescent lamp, CCFL, led light source to see through by leaded light point or leaded light groove after the optical principle calculating, under reflective membrane (reflecting plate) and diffusion barrier effect, changes line source or spot light into area source.For making the LGP can uniformly light-emitting, must be by various densitys, leaded light point not of uniform size, basic identical to guarantee light toward the efficient of all directions reflection.In the light reflected back LGP that the purposes of reflector plate (reflecting plate) is bottom surface of light guide plate is revealed out, be used for improving the service efficiency of light, improve brightness.Because LED is a kind of spot light, can not directly apply to illumination, directly use the eyes that can stimulate the people.Existing technology is to go into mode such as optical plane LGP and change spot light into area source by a lot of different material such as diffuser plate or monoblock sides of adding as reflection, lens, direct-injection type.Certainly will to increase energy consumption like this, reduce light efficiency and improve production cost.The needs of Economic Development can not have been satisfied.Because the LED light efficiency is more and more higher, and LED is a spot light and can not directly apply to illumination, so must reach the illumination purpose by the luminous form of secondary.Existing LED bulb is to adopt material shadings such as various lens, diffusion lampshade, carry out luminous not dazzle or the dazzling illumination effect of just reaching of secondary, and the materials such as lampshade of lens and diffusion usefulness have certain interception, can not penetrate light fully, cause losing most of energy consumption, cause light efficiency than defectives such as low and production cost raisings.
Summary of the invention
The present invention proposes LED LGP bulb that a kind of energy consumption and production cost are lower and light efficiency is higher and preparation method thereof in order to solve the technical barrier of above-mentioned LED bulb.
The LED LGP bulb that the present invention proposes, it comprises LGP, be located at the leaded light point on this LGP surface, be located at the led light source of LGP side, the transformer rectifier circuit that is connected with led light source, by the lamp holder that a radiator is connected with an end of described LGP, this lamp holder also is connected with described transformer rectifier circuit.
Preferably, described LGP periphery is provided with a lampshade, and this lampshade lamp holder is connected with described radiator.
Described LGP is at least any of rectangle, U-shaped, cruciform shape, hollow square column body or hollow cylinder.It can be made up of the LGP of a plurality of same shapes, can also be constituted by various difform LGPs.
Described transformer rectifier circuit can be located at described lamp holder inside, also can be to make independently rectifier and transformer, places outside the light fixture.
Described lamp holder is round or square; This lamp holder is the lamp holder of buckle-type or spiral connection.
Described LGP is made by any optical material such as acrylic, glass, PC.
Described leaded light point is made by any method such as printing, engraving, laser engraving, mould or corrosion.
Described LGP is made by methods such as mould or hot bendings.
The preparation method of the LED LGP bulb that the present invention proposes, its step is as follows:
Carry out the design of leaded light point as requested, and make the leaded light point on the surface of LGP;
According to the needs of design, adopt the method for mould or hot bending that LGP is made moulding;
Again led light source is located at the side of LGP;
At last lamp holder, radiator, led light source, LGP and transformer rectifier circuit assembling are connected.
Compared with prior art, the present invention has advantage:
(1) existing LED illumination is a spot light and can not directly be used as illumination and use, and can produce dazzle and dazzling, must have other materials to be used and carry out the luminous illuminating effect that just can reach of secondary, as materials such as lens, diffusion and light shields.The present invention can directly derive light by the LED LGP, reduces energy consumption, works together because the light transmittance of LGP (PMMA) material generally greater than 93%, is the best leaded light of LED, improves light efficiency, and (reducing material costs such as light source and diffusion) reduces cost;
(2) the present invention's application is more extensive, and the life-span is long, energy-conserving and environment-protective.Product is widely used in fields such as all kinds of illuminations, decorative lighting.
