Description
Technical field
The present invention relates to a kind of structure and forming method thereof of billboard display unit, specifically reflector and the manufacture craft thereof in a kind of lamp source.
Background technology
The built-in light source of emissive type indoor and outdoor billboard, the surface is provided with advertising design, and light source is luminous in billboard, and the surface of billboard is illuminated, and to such an extent as to the light transmission is arranged on advertising design.According to the development of present electric light source, this billboard-like overwhelming majority has used the fluorescent lamp of gas discharge.That this class light source has is linear, long discharge and luminous, so, can fluorescent lamp be arranged in billboard inside with the mode of array, luminous to consist of the face type.
Existing maximum application is that the fluorescent lamp with straight pipe type is arranged in parallel, and has each other a determining deviation, the advertising design plane parallel on its plane, place and billboard surface.This mode has its intrinsic defective: because there is spacing in fluorescent tube, so projecting the luminous flux of advertising design distributes also inhomogeneous in the plane, to such an extent as to occur significantly light and dark zebra striped on advertising design: the zone near fluorescent tube is brighter, zone corresponding between fluorescent tube is darker; Although enough dense degree can make up this inhomogeneous situation, weaken the effect of zebra striped, can bring huge energy consumption increase, the waste of light fixture cost.So this its optical system of self luminous billboard needs to improve.
Summary of the invention
For the deficiency of existing billboard, technical solution of the present invention problem to be solved is, reflector and the manufacture craft thereof in a kind of lamp source is provided, with the problem that overcomes be difficult to avoid when billboard uses the long tube type fluorescent light inhomogeneous, the zebra striped occurs.Its technical scheme is as follows:

The specific embodiment
As extremely shown in Figure 11 in Fig. 1, the schematic diagram of one embodiment of the invention;
The present embodiment with the reflector in lamp source, has mainly comprised reflector 10 and the light source 20 of fluted body; Wherein reflector 10, adjacent arrangement parallel to each other; And light source 20 is long tube T5 fluorescent-lamp-type, the reflector 10 grooves focal line position separately of being individually fixed in parallel to each other, and so-called focal line i.e. the line of these reflector 10 cross section optical focus.
As seen, process through reflector 10 from the light of light source 20, central rib 11 namely and the reflection of the part in the outside 12 thereof make the light output of light source 20 linear illuminators be converted into uniform diffused light; And, astigmatic band 13 is the dotted line type, be discontinuous protruding 14, this projection 14 has played good tunning effect, the part light of light source 20 can significantly be spread, made up the uniformity of depending merely on 12 reflection rays of central rib 11 and the outside, made the advertising design in reflector 10 fronts can obtain uniform illumination and good visual effect.
The present embodiment also has other Some features:
Due to the T5 fluorescent tube that has used high light efficiency, small size, so this scheme has compact conformation, the characteristics that light efficiency is high, the central rib 11 shown in Fig. 2 is 3-5mm with the vertical interval of light source 20, this vertical interval makes the light of light source 20 belows can have good angle of flare.And as shown in Figure 4, the projection 14 of this astigmatic band 13 is placed for long some shape, this astigmatic band 13 of its long edge, and its range scale is chosen as: the height 0.5-1mm of projection 14, width c scope 0.5-1mm, length b scope 4-10mm, centre-to-centre spacing scope 6-10mm.In the present embodiment, be highly 1mm, c=1mm, a=5mm, b=7.5mm has good dispersion effect, makes the advertising design brightness on surface even.
Except projection 14 its parameters of astigmatic band 13 had preferred version, some sizes of the present embodiment reflector 10 itself also had good optical property.As previously mentioned, because light source is the T5 fluorescent tube, so as shown in Figure 5, the cross section shapes that designs these reflector 10 its central ribs 11 is arc surface; The cross section shapes of the outside 12 reflectings surface outside its central rib is also arc surface, and this outside 12 is tangent with this central authorities' rib 11 junctions; Wherein
The arc surface angle α scope of the both sides of this central authorities' rib 11 is 70-74 °;
The radius of curvature R 1 of this central authorities' rib 11 is 15-20mm;
The radius of curvature R 2 of these outside 12 reflectings surface is 680-700mm;
The subtended angle β of these outside 12 reflectings surface is 155-161 °.All make its diffusion effect of light source of T5 fluorescent tube best in this scheme scope.Especially, for simplifying technique, Material Cost, central rib 11 shown in Figure 5, projection 14 are the form of integrated punching moulding, can adopt the aluminium section bar full wafer one time punching molded.
As shown in Figure 6, each reflector 10 of the present embodiment is independent moulding, so, when needs are arranged in same billboard, must make parallel connection, reflector 10 openings have two flangings 15 backwards, and every adjacent two reflectors, 10 its two adjacent flanging 15 symmetries are plugged in the both sides in a holddown groove 30, and it is fastening to insert screw 31 between this two flanging 15, as seen, this mode has very simple transmitter 10 structures, and its fixed part is few simultaneously, and technique is quick.
As shown in Figure 3, for ease of light source 20 is installed, have transverse tube 40 at the two ends of reflector 10, this transverse tube 30 is perpendicular with light source 20, and has fixed the lamp socket 50 that is used for installing this light source on it.This form is fixing simple, and number of components is few.
Fig. 7 to Figure 11 has showed the manufacture craft of the present embodiment:
Fig. 7 is the slave board step, and this step provides a smooth metallic plate 70, is placed between the patrix 50 and counterdie 60 of a diel; The core lower end of this patrix 50 has the shape of a central rib 51, and this central authorities' rib 51 both sides, top have two sections symmetrical composite parabolics; And, having with it parallel projection band 52 in the both sides of this central authorities' rib 51, this projection band 52 is the dotted line type of discontinuous point-like; The core upper end of counterdie 60 has the shape with the core lower end coupling of this patrix 50.
Fig. 8 has showed punch steps, this step pressing patrix 50 and counterdie 60;
Fig. 9 is the die sinking step, and this step is separated patrix 50 with counterdie 60, takes out the complete metallic plate of punching press, obtains a reflector 10 of moulding;
At last, Figure 10 has showed the flanging step, in this flanging step, reflector 10 openings is obtained two flangings 15 backwards towards reverse bending.So, just obtained possessing central rib 11, projection 14 and the reflector 10 of flanging 15.This form is very suitable for one-time formed mode, as long as the sheet metal 70 of suitable dimension can have efficient batch efficient.
As Figure 11, on the technique patrix 50 of the present embodiment, projection band 52 is the form of a mold insert, and pegging graft vertically upward is matched with in the core of this patrix 50, and this projection band 52 has the insert body 56 of a band shape and the projection 55 that distributes in the one side.Above-mentioned projection 14 that this projection 55 has been moulding.And the cross section of the projection 55 of the present embodiment is the rectangle person, this rectangle length direction with the bearing of trend of projection band 52 in the same way, consisted of the structure of above-mentioned astigmatic band.The form that projection band 52 is treated to mold insert is beneficial to the different specification of replacing, is shaped to different astigmatic bands, can ensure the service life that mould is longer simultaneously.
The above, only for preferred embodiment of the present invention, therefore can not limit according to this scope of the invention process, the equivalence of namely doing according to the scope of the claims of the present invention and description changes and modifies, and all should still belong in the scope that the present invention contains.
