Description
Technical field
The present invention relates to the reflex reflector that a kind of guiding lamp radiant distributes, relate in particular to a kind of use in lamp box, eliminate the reflex reflector of the rib line between two fluorescent tubes.
Background technology
Traditional lamp box is generally the lamp box of built-in lamp, and its inside is provided with several fluorescent tubes that be arranged in parallel.Owing to have certain interval between two adjacent fluorescent tubes, cause the vacancy of light, the discontinuous or uneven phenomenon of light can appear in the back lamp box picture of turning on light, and produces black-tape, has a strong impact on the effect of lamp box and picture.
In order to reduce rib line phenomenon, generally the display surface at lamp box is provided with softbox in addition, and strengthens distance between lamp box backboard and the plate reducing illuminance, thereby slackens the black-tape phenomenon.But this lampshade structure can not be eliminated rib line phenomenon fully, and owing to widened distance between lampshade and the softbox, can cause that lamp house thickness is big, volume is big, and waste raw material and electric energy are not only uneconomical but also not attractive in appearance.
The present inventor had once carried out various improvement to lamp box, comprising: 1, the reflector of arc is set in the part of the close backboard of lamp box fluorescent tube, and the light emission of fluorescent tube being shone toward back plate is to the fluorescent tube periphery; 2, the reflecting angle that connects two curved reflectors is set between adjacent two curved reflectors.Through above-mentioned improvement, the lighting effect of lamp box has obtained certain improvement, can reduce or eliminate lamp box and produce rib line phenomenon, increases the illuminance on the softbox, makes the light effects of lamp box better.
But prior art still can not provide makes more standardization, operate more simple, the light guiding device of sheen better effects if.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the invention provides a kind ofly make the light of fluorescent tube more even, soft, and make fluorescent tube reflector simple, easy for installation.
The invention provides and a kind of a plurality of fluorescent tubes are carried out the reflector of leaded light, it is characterized in that: reflector is arranged between fluorescent tube rear and two the adjacent fluorescent tubes; Above-mentioned reflector has bossing and sunk part, and wherein, the part that reflector is positioned at the rear of fluorescent tube forms concave arc, the light at reflection fluorescent tube rear; The part of reflector between two fluorescent tubes is to showing that direction forms projection, and guiding light is to showing the direction irradiation.
The present invention provides a kind of lamp box in addition, comprise backboard, Graphic Panel, many fluorescent tubes, it is characterized in that: between Graphic Panel and the fluorescent tube and between two adjacent fluorescent tubes reflector is being set, above-mentioned reflector has bossing and sunk part, wherein, the part that reflector is positioned at the rear of fluorescent tube forms concave arc, the light at reflection fluorescent tube rear; The part of reflector between two fluorescent tubes forms projection to the Graphic Panel direction, and guiding light shines to the Graphic Panel direction.
By lamp box provided by the invention, make that the light of fluorescent tube is more even, soft, and make simple, easy for installation.Because reflector can compensate the light in half-light district with the light retroeflection to the side of the reflector of fluorescent tube both sides, thereby reach the purpose of eliminating the rib line.
In addition,, the distance between the fluorescent tube be can widen, fluorescent tube and energy-conservation effect reduced thereby reach by reflector of the present invention.

The specific embodiment
Shown in Fig. 1-12, shown the reflex reflector that guiding lamp radiant provided by the invention distributes.In the accompanying drawings, be distributed as example, shown the setting of reflector with the light source in the guiding lamp box.But, be understandable that the present invention is equally applicable to guide the distribution of light of general lighting.
As Figure 1-3, shown that the reflector top is pointed embodiment.As shown in Figure 1, the single face lamp box comprises backboard 3, and Graphic Panel 2 is arranged on a plurality of fluorescent tubes 1 on the backboard 3 abreast.Among the present invention, reflector 4 is arranged between Graphic Panel 2 and the fluorescent tube 1, and between two adjacent fluorescent tubes 1.The zone of above-mentioned reflector between Graphic Panel 2 and fluorescent tube 1 forms concave arc; The zone of reflector between two fluorescent tubes 1 is to Graphic Panel direction projection.
The top reflector has top 41 and sidewall 43.In the reflector that Fig. 1-3 demonstrates, the top 41 of top reflector is pointed, and it is recessed to the concave arc panel that forms, the convex arc panel facing plate directly, protrude to Graphic Panel to Graphic Panel that sidewall 43 can be respectively.
The bottom reflector has middle body and side arm, and above-mentioned middle body is a curved surface, and curved surface is arranged on the below of fluorescent tube 1, catches the fluorescent tube bottom, and the light that fluorescent tube 1 is launched toward back plate is directed to the display board direction.Particularly, the reflector of light 1 both sides can be mapped to light on the Graphic Panel 2, has compensated the light in black-tape zone, reaches the purpose of eliminating the rib line.The shape of the sidewall of bottom reflector is corresponding to the shape of top reflector sidewall 43.
Above-mentioned top reflector, bottom reflector can be distinguished moulding, form two independent parts, are assembled into one then, also can be one-body molded.
Shown in Fig. 4-6, shown that the reflector top is the embodiment of arc.
In the reflector that Fig. 4-6 demonstrates, the top 41 of top reflector is an arc, and it is recessed to the concave arc panel that forms, the convex arc panel facing plate directly, protrude to Graphic Panel to Graphic Panel that sidewall 43 can be respectively.
Bottom reflector middle body is a curved surface, and curved surface is arranged on the below of fluorescent tube 1, catches the fluorescent tube bottom.The shape of the sidewall of bottom reflector is corresponding to the shape of top reflector sidewall 43.
Shown in Fig. 7-9, shown that the reflector top is the embodiment of spill.As shown in the figure, the top 41 of top reflector is the spill to Graphic Panel 2 depression, and it is recessed to the concave arc panel that forms, the convex arc panel facing plate directly, protrude to Graphic Panel to Graphic Panel that sidewall 43 can be respectively.
Bottom reflector middle body is a curved surface, and curved surface is arranged on the below of fluorescent tube 1, catches the fluorescent tube bottom.The shape of the sidewall of bottom reflector is corresponding to the shape of top reflector sidewall 43.
Except the alteration of form of reflector, can also be as shown in figure 12, towards the direction of Graphic Panel 2 reflecting angle 10 is set at fluorescent tube 1.Acting as of above-mentioned reflecting angle: light-illuminating is reflexed to the bottom reflector to the light of Graphic Panel 2, reflex on the Graphic Panel 2 part again away from fluorescent tube.
In addition, can also be as shown in figure 11, be provided with two at light 1 towards the direction of Graphic Panel 2 and separate the shadow shields 11 that are provided with along fluorescent tube axis symmetry.Acting as of above-mentioned shadow shield 11: weaken the light of the direct directive Graphic Panel 2 of fluorescent tube, light is reflexed on the Graphic Panel 2 part away from fluorescent tube by the bottom reflector.
In addition, also can reflector be arranged in the double-faced lamp to shown in Figure 10.The tow sides of double-faced lamp all are provided with Graphic Panel 2, and reflector 2 has raised or sunken part.Fluorescent tube is arranged on reflector towards Graphic Panel 4 and forms raised or sunken part.Like this, reflector of the present invention also can be used for double-faced lamp.
