Description

Reflecting plate and the LED flat lamp equipped with the reflecting plate
Technical field
The present invention relates to LED field, and in particular to a kind of reflecting plate for LED and the LED equipped with the reflecting plate are put down Plate lamp.
Background technology
The defects of now reflective sheeting in the art has water ripples and expanded with heat and contract with cold.The defects of water ripples, refers to, is put down in LED During the use of plate lamp, the plane corner of reflective sheeting can warp, not smooth enough, and middle position meeting air-blowing, so as to whole The shape for seeming ripple, referred to as water ripples are formed on body.Because the swells branch of water ripples is equipped with air, it is not adjacent to and leads Tabula rasa, whole LED flat lamp just occur the phenomenon of light and dark, cause the result that light is uneven when work.The heat The defects of swollen shrinkage, is, because the environment used has different temperature, for example (,) it is cold in winter and hot in summer, can be to the thing of LED flat lamp Material can be further exacerbated by the reaction expanded with heat and contract with cold again with the reaction expanded with heat and contract with cold, the temperature of lamp body light, so as to further The defects of aggravation forms water ripples.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to propose a kind of to overcome water ripples and expand with heat and contract with cold defect Reflecting plate and the LED flat lamp equipped with the reflecting plate.
Used technical scheme is：
A kind of reflecting plate, it is the saturating benzene and 10-30wt% light reflection master batch for changing benzene, 20-40wt% by 40-60wt% It is manufactured；The light reflection master batch is by the titanium white of 80-90wt% makrolon, 5-10wt% dispersant and 5-10wt% Made of powder.
Wherein, reflecting plate is also known as reflector, saturating benzene and to change benzene be being commonly called as the art, and saturating benzene is general purpose grade polyphenyl second Alkene, english abbreviation GPPS；It is shock resistance polystyrene to change benzene, english abbreviation HIPS.In this formula, saturating benzene and change benzene Effect be, make reflecting plate that there is stronger pliability and high impact properties, and cooperate with light reflection master batch be fused into gram Take the effect of reflecting surface water ripple phenomenon.The makrolon of light reflection master batch has anti-flammability, impact resistance, heat resistance in itself, Its impact resistance can be with changing benzene and saturating benzene Synergistic；Its heat resistance can resist the change of temperature, overcome showing for heat expansion pyrocondensation As.The effect of dispersant is to make have preferable interface compatible between makrolon and titanium dioxide, improves titanium dioxide in poly- carbon Dispersed homogeneous degree in acid esters, so as to improve reflectivity.Titanium dioxide has preferable refractive index, mixes in makrolon, refraction The increase of rate can increase reflectivity.
Preferably, the dispersant is silicone dispersion agent.The silicone dispersion agent of both ends polarity, the polar group of its one end Group can be taken aim at admittedly on titanium dioxide surface, and the polar group of the other end is compatible with makrolon, so as to preferably scattered makrolon And titanium dioxide.
Preferably, the titanium dioxide is rutile type titanium white 2233.The titanium dioxide of this type compare with it is other kinds of Titanium dioxide has higher refractive index, so as to have higher reflectivity.
Prepare light reflection master batch when, can in high-speed mixer the makrolon of mixing formula amount, dispersant and titanium white Powder, then it is made again through melting extrusion, granulation.
The light reflection master batch made remixes changing benzene and saturating benzene melting compacting or being molded into plate for formula ratio, cools down and is made anti- Penetrate plate.
A kind of LED flat lamp, including the reflecting plate described in framework, LED, light guide plate, diffuser plate and any of the above-described scheme, The LED is arranged on the inner side of the framework, and the diffuser plate, the light guide plate and the reflecting plate are sequentially overlapped fitting peace In the framework, and the LED is set to be located at the both sides of the light guide plate；The light guide plate connects with the reflecting plate Contacting surface is provided with multiple salient points.
In this structure, the conducting path of light is as follows：The light of LED first is sent to light guide plate, light guide plate by salient point from Different directions are oriented to reflecting plate, the unidirectional light of baffle reflection, then are exported through light guide plate, spread and go out through diffuser plate. During this, it because reflecting plate can overcome water ripples and defect of expanding with heat and contract with cold, therefore can be more uniformly distributed light diffusion, light Efficiency is more preferably.
Preferably, the diffuser plate be by 40-60wt% change benzene, 20-40wt% saturating benzene and 10-30wt% light expand Dissipate made of master batch；The smooth diffusion master batch is by 80-90wt% makrolon, 5-10wt% light diffusing agent and 5- Made of 10wt% fire retardant.
In the formula of diffuser plate, saturating benzene is with the effect for changing benzene, makes diffuser plate that there is stronger pliability and height to resist Impact, and cooperate with light diffusion master batch to be fused into the effect for further overcoming water ripple phenomenon, the poly- carbon of light diffusion master batch Acid esters has anti-flammability, impact resistance, heat resistance in itself, and its impact resistance can be with changing benzene and saturating benzene Synergistic；Its is heat-resisting Property can resist the change of temperature, overcome the phenomenon of heat expansion pyrocondensation；Its anti-flammability can be with fire retardant Synergistic.The work of light diffusing agent With the diffusivity and uniformity for being to strengthen light.
Preferably, the light diffusing agent is organic silicon resin ball-shaped micro powder.Such as Japan's more letter production can be selected KMP-590 or MP-470, particle diameter is preferably at 1-5 μm.
Preferably, the makrolon is bisphenol A polycarbonate.
Preferably, the fire retardant is organic silicon fibre retardant.Organic silicon fibre retardant is with organic silicon resin ball-shaped micro powder Organosilicon material, it can be easier to merge on bisphenol A polycarbonate in the preparation.
It is highly preferred that the organic silicon fibre retardant is polyphenyl methyl siloxane, more phenyl silsesquioxanes and phenol end Mixture more than one or both of base dimethyl siloxane.
Light diffusion master batch is that light diffusing agent and fire retardant are homogeneously incorporated into makrolon in the preparation.This can be incited somebody to action Three kinds of raw materials are smashed with banbury and uniformly mixed in high-speed mixer, are then made again through melting extrusion, granulation.
The light diffusion master batch made remixes changing benzene and saturating benzene melting compacting or being molded into plate for formula ratio, cools down to be made and expands Fall apart.
Preferably, the light guide plate is made of polycarbonate pc.So, reflecting plate, light guide plate and diffuser plate are equal Material containing makrolon, when triplicity is integral, preferably it can be bonded each other, without gap, so that Non-uniform light caused by air will not be housed, i.e., the water ripples between further eliminating and defect of expanding with heat and contract with cold.
The beneficial effects of the present invention are：
1. the reflecting plate of the present invention and the LED flat lamp equipped with the reflecting plate solve water ripples and what is expanded with heat and contract with cold lacks Fall into, more energy efficient environmental protection.
2.LED flat lamps are luminous uniform, and luminous efficiency reached more than 96% in 20000 hours.
The guide-lighting conversion efficiency 90-96% of the light guide plate of 3.LED flat lamps.
