Description

A kind of tracing lamp box

Technical field

The utility model relates to a kind of lamp box, more specifically is meant a kind of tracing lamp box.

Background technology

The lamp box that is used to copy word, figure at present generally all by general T 4, T5 fluorescent tube as light source, be clouded in the light-emitting area back to realize the conversion of line source to area source, the life-span is low, power consumption is high, have certain potential safety hazard, complex structure, thick and heavy clumsiness.

Summary of the invention

The main purpose of the utility model is to provide a kind of tracing lamp box, its can solve the life-span that present tracing lamp box exists low, power consumption is high, complex structure, thick and heavy problem, it adds LGP, the frosted plate can reduce the shadow phenomenon.

The another purpose of the utility model is to provide a kind of tracing lamp box simple, easy to use of making.

The technical scheme that the utility model adopts is: a kind of tracing lamp box; Comprise box-frame, luminescence unit, LGP, frosted plate, transparent acrylic panel and base plate, wherein, this box-frame has first draw-in groove and is positioned at second draw-in groove under this first draw-in groove; Wherein, This luminescence unit is placed in this first draw-in groove, and this leaded light edges of boards portion is connected in this first draw-in groove corresponding with this luminescence unit, and this frosted plate is arranged on this LGP; This transparent acrylic panel is arranged on the top of this frosted plate and is fixed on this box-frame, and the limit portion of this base plate is connected in this second draw-in groove.

This luminescence unit is a LED lamp bar.

This box-frame is to be spliced each other through four coupling assemblings by the four edges frame, and wherein, each coupling assembling all comprises gusset and the rounded corner spare that is used to splice per two frames.

The beneficial effect of the utility model is: the utility model structurally comprises box-frame, luminescence unit, LGP, frosted plate, transparent acrylic panel and base plate; Wherein, This box-frame has first draw-in groove and is positioned at second draw-in groove under this first draw-in groove, and wherein, this luminescence unit is placed in this first draw-in groove; This leaded light edges of boards portion is connected in this first draw-in groove corresponding with this luminescence unit; This frosted plate is arranged on this LGP, and this transparent acrylic panel is arranged on the top of this frosted plate and is fixed on this box-frame, and the limit portion of this base plate is connected in this second draw-in groove.This luminescence unit is a LED lamp bar.The utility model its can solve the life-span that present tracing lamp box exists low, power consumption is high, complex structure, thick and heavy problem, it adds LGP, the frosted plate can reduce the shadow phenomenon.And also have and make effect simple, easy to use.

Fig. 2 is the overall schematic of the utility model.

Fig. 3 is the explosive view of Fig. 2.

The specific embodiment

Extremely shown in Figure 3 like Fig. 1 is a kind of preferable practical implementation example of the utility model; A kind of tracing lamp box; Comprise box-frame 10, luminescence unit 20, LGP 30, frosted plate 40, transparent acrylic panel 50 and base plate 60, wherein, this box-frame 10 has first draw-in groove 11 and is positioned at second draw-in groove 12 under this first draw-in groove 11; Wherein, This luminescence unit 20 is placed in this first draw-in groove 11, and these LGP 30 limit portions are connected in this first draw-in groove 11 corresponding with this luminescence unit, and this frosted plate 40 is arranged on this LGP 30; This transparent acrylic panel 50 is arranged on the top of this frosted plate 40 and is fixed on this box-frame 10, and the limit portion of this base plate 60 is connected in this second draw-in groove 12.

Further, this luminescence unit 20 is a LED lamp bar.In concrete the use, luminescence unit 20 also can be CCFL can reach very approaching effect, but security and service life are all less than LED.Most preferred embodiment of the luminescence unit 20 of the utility model is a LED lamp bar, works as as light source with the LED lamp to be not limited to the LED lamp source.

This box-frame 10 is to be spliced each other through four coupling assemblings 112 by four edges frame 111, and wherein, each coupling assembling 112 all comprises gusset 113 and the rounded corner spare 114 that is used to splice per two frames 111.

The transparent acrylic panel of the utility model, the wide silver color frame of silk-screen 26mm, its frosted plate is used for eliminating " rainbow " phenomenon that occurs when writing, and its LGP is realized the conversion of line source to backlight

The product that the advantage of the utility model is new is to combine LED photoelectric technology and LGP plate technique, and it is about 80% to make product compare power saving with traditional like product, reduces to 17mm by traditional like product 150-200mm thickness.The direct current 12V low voltage designs of its LED lamp bar improves security performance greatly, and the fillet of hommization is handled.

The key of the LGP lighting engineering of the utility model is the total reflection effect of light in PMMA.Reflection and refraction can take place in light when unconventional two kinds of transparent mediums; When light from refractive index greater than the transparent medium of air during the directive air; Because the difference of refractive index; Total reflection will take place greater than the certain angle time in incidence angle θ on the interface, no longer include light and penetrate medium, that is to say that light only depends on the absorption of medium to light in the inner loss of medium; And do not have loss (light reflex time on metal covering can lose 10%-15% usually) at reflex time on the interface, and the PMMA LGP has utilized this characteristic just.

Embodiment of the utility model and accompanying drawing are just in order to show the design concept of the utility model, and the protection domain of the utility model should not be confined to this embodiment.

Can find out that through top narration the purpose of design of the utility model can effectively implement.The part of embodiment has been showed the purpose of the utility model and has been implemented function and structural themes, and comprised other the replacement that is equal to.

Therefore, the right of the utility model constitutes the equivalence that comprises other to be implemented, and the concrete right scope is with reference to claim.
