Description

A kind of LED panel lamp of specular removal

Technical field

The utility model is related to illuminating product technical fields, more particularly, to a kind of LED panel lamp of specular removal.

Background technology

It sends out and develops rapidly with industrial technology, energy conservation and environmental protection is increasingly paid attention to by human society, therefore leads to LED light Tool is rapidly developed and extensive use, especially with LED light source, light guide plate, reflectance coating, diffusion board structure panel light more It is to apply incisively and vividly.Panel light have many advantages, such as fashionable appearance, it is simple in structure, shine uniformly, dazzle it is small, office, The occasions such as office building, house decoration, school, hospital are used widely.At the same time, people also focus more on the hair of panel light Light efficiency, it is energy saving the problems such as.If on June 24th, 2016 applies, 201610467794.1 disclosed invention of Patent No. is special Profit, the mainly microballon by being equipped with protrusion on light guide plate close to reflectance coating side so that panel light, which has, loses small, hair The advantages that light is uniform；On May 7th, 2015 applies for that the invention LED panel lamp of Patent No. 201510229413.1, is in the market The LED panel lamp generally used, internal light guide structure is mainly diffuser plate, light guide plate, reflectance coating and backboard etc., that is, completes light Line imports and exports process.How to be improved in existing LED panel lamp structure, is shone with further increasing LED panel lamp The uniformity and luminous efficiency of intensity had become LED panel lamp industry technical barrier urgently to be resolved hurrily already.

Invention content

The purpose of this utility model is intended to overcome the shortcomings of the prior art, provides a kind of simple structure, can be notable Improve the LED panel lamp of light emission luminance and luminous efficiency.

In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：

A kind of LED panel lamp of specular removal, including frame, the LED light bar being set in frame, and be set on frame And diffuser plate, light guide plate, reflectance coating and the backboard stacked gradually；One transparent and light transmission is set between the diffuser plate and light guide plate The good diffusion barrier of performance.

Preferably, the thickness of the diffusion barrier is 0.05~0.5mm.

Preferably, the material of the diffusion barrier is PET or PC.

Preferably, the appearance and size of the diffusion barrier is same as or slightly smaller than guide-lighting board size with guide-lighting board size.

Compared with prior art, the utility model has the following advantages that：

(1) a layer thickness is very thin, transparent and light transmission by increasing between light guide plate and diffuser plate for the utility model Good diffusion barrier, this diffusion barrier can greatly improve the light emission luminance of LED panel lamp, to improve shining for LED panel lamp Efficiency.

(2) the utility model uses very thin diffusion barrier, has filled up the gap between light guide plate and diffuser plate, has reduced light Loss, and increase diffusing reflection number, it is projected after passing through diffuser plate after multiple diffusing reflection so as to cause light.Pass through increase Diffusion barrier causes to send out identical luminous flux in LED light bar, greatly improves the diffusing reflection number of light, eventually leads to In the case of equal-wattage, the luminous efficiency of whole lamp greatly improved using diffusion barrier, about 40% light can be improved by test Effect.

Description of the drawings

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it can also be obtained according to these attached drawings other attached drawings.

Fig. 1 is the structural exploded view of the one of specific embodiment of the utility model.

Fig. 2 is the structural schematic diagram of partial component in Fig. 1.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not under the premise of making the creative labor The every other embodiment obtained, shall fall within the protection scope of the present invention.

The LED panel lamp of specular removal shown in Fig. 1-4, including frame 2, the LED light bar 9 being set in frame 2, and setting In on frame 2 and the diffuser plate 4, light guide plate 6, reflectance coating 7 and the backboard 8 that stack gradually；Between the diffuser plate 4 and light guide plate 6 One transparent and diffusion barrier 5 that light transmission is good is set.

Particularly, the thickness of the diffusion barrier 5 is 0.05~0.5mm.

Particularly, the material of the diffusion barrier 5 is PET or PC.

Particularly, the appearance and size of the diffusion barrier 5 is same as or slightly smaller than 6 size of light guide plate with 6 size of light guide plate.

Its assembling process is as follows：

(1) as shown in Figure 2, (front to the back side) places diffuser plate 4, diffusion barrier 5, light guide plate 6, reflectance coating from bottom to up 7 and backboard 8 and arrange alignment；

(2) LED light bar 9 is inserted into four side proximate matter A, B such as Fig. 3, LED light bar 9 is connected after welding, and by LED light bar 9 One end be welded to connect with power outlet 10；

(3) such as Fig. 4, four side proximate matter A, B are assembled by diagram with frame angle 3, and is screwed securely.

(4) such as Fig. 1, the DC output end of power supply 1 is inserted into the power outlet 10 of LED light bar i.e. by plug 11 It can.

The LED panel lamp is mainly used as stationary body by aluminum frame 2, for fixing entire panel light structure, surrounding Four side proximate matter A, B of frame 2 are linked into an integrated entity by frame angle 3, and a LED light bar is respectively inserted on the inside of four side proximate matter A, B 9 light emitting source as lamp body, have successively from front to the back side inside frame diffuser plate 4, diffusion barrier 5, light guide plate 6, reflectance coating 7, Backboard 8, internal LED light bar 9 are wired to power outlet 10, and 1 DC output end of DC power supply is inserted into LED light bar Power outlet 10 provides power supply to LED light bar 9.After LED light bar is powered, LED light bar light-emitting line is injected into light guide plate, in addition Back is re-introduced into light guide plate after having reflectance coating, light to be reflected from reflectance coating, a part of light is sent out after being injected into reflectance coating Raw to be reflected into light guide plate, light again passes through diffusion barrier 5 after passing through light guide plate, and diffusion barrier is very thin, filled up light guide plate with Gap between diffuser plate reduces light loss, and increases diffusing reflection number, so as to cause light after multiple diffusing reflection It is projected after diffuser plate.After increasing diffusion barrier, causes to send out identical luminous flux in LED light bar, greatly improve light The diffusing reflection number of line, then greatly improved the luminous efficiency of whole lamp.

The illumination test of the present embodiment is as shown in the table with the illumination test comparison of existing LED panel lamp：

By comparing it is found that under close power situation, the luminous efficiency of whole lamp greatly improved using diffusion barrier, can carry The light efficiency of height about 40%.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection domain within.
