Abstract
The utility model relates to a backlight on a mobile hard disk. The purpose is that the lighting part of a provided lighting plate should be distributed in a three-dimensional structure, and the lighting plate has the characteristics of simple structure and low manufacturing cost. The technical scheme is that the mobile hard disk backlight comprises a trapezoidal light guiding plate and a lead wire which is provided with a plug and is electrically communicated with the light guiding plate; a rectangular light-transmitting bar transversely extending and protruding forwards is arranged at the upper end of the light guiding plate; a notch is arranged at the lower part of the light guiding plate; an LED lighting assembly is arranged in the notch; the lead wire extends into the notch of the light guiding plate from outside and is electrically connected with the lighting assembly; a photomask is covered at the front of the light guiding plate and the part below the light-transmitting bar; a light reflecting film is adhered at the back and the periphery of the light guiding plate; the LED lighting assembly is glued and fixed on the light guiding plate by UV (Ultraviolet) adhesive; a plurality of mesh points formed by protruding and focusing are arranged at the back of the light-transmitting bar at the upper end of the light guiding plate; a light slowing bar higher than the light-transmitting bar is formed by the further extending of the top end of the light guiding plate for a long distance; and slope-like illuminating surfaces are respectively arranged at two ends of the light-transmitting bar.
Description
Technical field
The utility model relates to the backlight on a kind of demonstration and light decorations articles for use, the especially portable hard drive.
Background technology
Conventional portable hard drive back light source structure is: be in the bottom notch of trapezoidal sheet LGP 1 the LED luminescence component is housed, one lead 2 that has a plug 3 is electrically connected with this luminescence component from the notch of LGP is stretched in the outside, and the back side of LGP is adhesively fixed on the LED luminescence component on the LGP by bonded adhesives by reflective membrane 4.When the plug energising made the LED luminescence component luminous, light promptly conducted the upper end that is crossing to LGP from LGP, and the rectangle light transmission strip of LGP upper end just sends light (two dimensional surface is luminous); Because LGP is installed on the shell of portable hard drive, thereby makes the profile of portable hard drive obtain tangible optics decorative effect.
According to the market demand, the design of the shell of portable hard drive requires the sheet LGP to send light at three-dimensional; Obviously need the ray structure of existing portable hard drive backlight be improved.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of improvement of portable hard drive backlight is provided, and the luminous site of the luminous plaque in this backlight should be three-dimensional structure and distribute, and has characteristics simple in structure, low cost of manufacture.
The utility model has adopted following technical scheme:
A kind of portable hard drive backlight, comprise one be trapezoidal LGP and with the lead that has plug of LGP electric connection; The upper end of LGP be shaped on an extending transversely and toward the place ahead outstanding rectangle light transmission strip, the LGP bottom is shaped on a notch, and the LED luminescence component is housed in the notch, described lead is electrically connected with this luminescence component from the notch of LGP is stretched in the outside; LGP front, the following position of light transmission strip are coated with photomask; The back side of LGP and the surrounding of LGP are along being stained with reflective membrane, and described LED luminescence component is fixed on the LGP by gluing the connecing of UV; The back side of the light transmission strip of described LGP upper end is shaped on by a plurality of projectioies assembles the site that forms; The slow striation that some distance formation one are higher than light transmission strip is also up extended on the top that it is characterized in that described LGP, and the two ends of described light transmission strip are shaped on the slope shape transparent surface respectively.
1-5mm is up extended on the top of described LGP.
Described site and light transmission strip coincide in the projection at the LGP back side.
Operation principle of the present utility model is: after this portable hard drive backlight energising, the light that the LED luminescence component sends, in LGP, conduct and just from the site, disperse, also disperse simultaneously to the slope shape transparent surface at light transmission strip two ends to the light transmission strip front through the light at position, site (forming) by a plurality of projectioies; Thereby these positions just become and are the luminous site, make light transmission strip front and two ends all send light; Because these luminous sites are corresponding one by one with display window on the portable hard drive shell, thereby finish function and the effect that demonstration and light are adornd.
The beneficial effects of the utility model are: the two ends of light transmission strip are shaped on the slope shape transparent surface, refraction by luminous site, make the front and the two ends of light transmission strip can both send light, thereby obviously strengthened the extraneous adornment effect of portable hard drive, satisfied the market demand.And, because the top of LGP is shaped on slow striation, make the uniformity of the light that light transmission strip sends and soften all be significantly improved, promoted product specification.In addition, the making of LGP only needs mould is changed a little, so also processing is simple, manufacturing cost is lower naturally.

The specific embodiment
As shown in the figure: the portable hard drive backlight, comprise one be trapezoidal LGP 1 and with the lead that has plug 32 of LGP electric connection; The upper end of LGP be shaped on an extending transversely and toward the place ahead outstanding rectangle light transmission strip 1-1, the LGP bottom is shaped on a notch 1-2, and the LED luminescence component is housed in the notch, described lead is electrically connected with this luminescence component from the notch of LGP is stretched in the outside; LGP front, the following position of light transmission strip are coated with photomask 5; The back side of LGP and the surrounding of LGP are along being stained with reflective membrane 4, and described LED luminescence component is fixed on the LGP by gluing the connecing of UV; The back side of the light transmission strip of described LGP upper end also is shaped among the site 1-5(Fig. 2 that is formed by a plurality of projection gatherings to be represented with hatching); The above structure all structure with existing portable hard drive backlight is identical.
Improvement of the present utility model is: the slow striation 1-6 that some distances (1-5mm) formation one is higher than light transmission strip is also up extended on the top of described LGP; As recommendation, the height of described slow striation 1-6 is to show among the 5mm(figure, and slow striation is trapezoidal).
The light transmission strip profile that the two ends of described light transmission strip also are shaped among transparent surface 1-10(Fig. 4, Fig. 5 of slope shape is trapezoidal).
In addition, described site and light transmission strip coincide in the projection at the LGP back side (be both area equal and opposite in directions, both mutual projected positions overlap); The projecting height of described projection is 0.01 ~ 0.1mm.These structures are all identical with existing backlight.
