Abstract

The utility model provides an advertising lamp-box light source, which belongs to the technical field of advertising lamp-box light sources. The prior advertising lamp-box has the main shortcoming that a fluorescent tube is installed inside the lamp box as a light source, thereby resulting in relatively high energy consumption and advertising cost. The advertising lamp-box light source comprises LED lamps, a light guide plate and a support frame, wherein, the LED lamps and the light guide plate are installed on the support frame respectively, the light guide plate comprises a reflective layer and a photic zone made of translucent materials, the photic zone includes a light inlet surface, a reflective surface and a light outlet surface, the support frame includes a radiating fin, an installation groove and a back plate, the LED lamps are arranged in the installation groove, the upper end of the light guide plate is clamped in the installation groove, the light inlet surface in the photic zone is clung to the LED lamps, the upper part of the reflective layer in the light guide plate is clung to the back plate in the support frame, the reflective layer is tightly jointed with the reflective surface in the photic zone, and more than two LED lamps are arranged in the installation groove. When used as an advertising lamp-box light source, the utility model has the advantages of long service life, low energy consumption, good illuminating effect, and low advertising cost.

Description

A kind of advertising lamp box light source

Technical field

The utility model relates to light source field, particularly relates to a kind of advertising lamp box light source.

Background technology

LED is the abbreviation of English Light Emitting Diode (light emitting diode), and it is the high-performance solid light source that a kind of novel faint electric energy of usefulness just can be luminous.First commercialization of 20 middle of century LED light emitting diode appears on the market, and through the course in surplus 50 years, its performance was constantly improved, and manufacturing cost constantly descends, and has obtained the rapid progress that attracts people's attention.LED has obtained using widely with advantages such as its intrinsic high efficiency, long-life, low-loss, vibration resistance, response speed piece, volume are little.The advertising lamp box of prior art mainly at the inner fluorescent tube of installing of lamp box as light source because the fluorescent tube volume is bigger, thereby advertising lamp box also will make greatlyyer, so advertising cost is higher; The fluorescent tube power consumption is more, thereby advertising cost is higher; Because fluorescent tube is shorter service life, will in time change after fluorescent tube is scrapped again, untimely replacing will influence advertising results, and in time changes trouble, and increases advertising cost.Advertising lamp box market wishes that urgently long service life, a kind of advertising lamp box light source that advertising lighting is effective, advertising cost is lower come out.

The utility model content

Technical problem to be solved in the utility model is, satisfy the active demand in advertising lamp box market, a kind of advertising lamp box light source is provided, this advertising lamp box light source uses LED to make light source, its long service life, advertising lighting are effective, light import behind the LGP reflective evenly, can produce enough brightness, have power saving and athermic advantage, thereby reduce advertising cost.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of advertising lamp box light source, comprise the LED lamp, LGP and bracing frame, LED lamp and LGP are installed on the bracing frame respectively, LGP comprises reflector layer and the photic zone made from light-transmitting materials, it is characterized in that: photic zone comprises incidence surface, reflective surface and exiting surface, bracing frame comprises fin, mounting groove and backboard, the design of LED lamp is in mounting groove, the LGP upper end is fastened in the mounting groove, incidence surface in the photic zone is close to the LED lamp, the backboard in the bracing frame is close on reflector layer top in the LGP, and the reflective surface in reflector layer and the photic zone closely combines.

In technique scheme, design has the LED lamp more than 2 in mounting groove.

Described fin, mounting groove and backboard are overall shaped into one.

Exiting surface in the photic zone is rectangle or square.

Reflective surface in the described photic zone is parabolic shape, and reflector layer also is parabolic shape with the corresponding face that closely combines of reflective surface in the photic zone.

The beneficial effects of the utility model are: owing to used led light source in advertising lamp box, LED lamp long service life, energy consumption are low, thereby reduce advertising cost, and this is that the fluorescent tube of prior art is difficult to realize; Because the reflective surface in the photic zone is parabolic shape, reflector layer also is parabolic shape with the corresponding face that closely combines of reflective surface in the photic zone, thereby the light of LED lamp enters photic zone, run into reflector layer after the reflector layer reflection, form collimated light beam, collimated light beam penetrates from exiting surface, makes the light homogeneous and bright of throwing photograph, produces enough brightness; The effect that the bracing frame of being made by aluminum material has installation and dispels the heat, the fin of being made by aluminum material also has the effect of heat radiation, thereby this advertising lamp box light source has power saving and athermic advantage, be easy to apply, and advertising lighting is effective, advertising cost is lower; Do not pollute the environment after LGP is discarded, meet energy conservation and environment protection.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an exploded view of the present utility model.

Among the figure, 1, the LED lamp; 2, reflector layer; 31, incidence surface; 32, reflective surface; 33, exiting surface; 4, fin; 5, mounting groove; 6, backboard.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Referring to Fig. 1 and Fig. 2, the described a kind of advertising lamp box light source of present embodiment, comprise LED lamp 1, LGP and bracing frame, LED lamp 1 and LGP are installed on the bracing frame respectively, LGP comprises reflector layer 2 and the photic zone made from light-transmitting materials, it is characterized in that: photic zone comprises incidence surface 31, reflective surface 32 and exiting surface 33, bracing frame comprises fin 4, mounting groove 5 and

backboard

6,1 design of LED lamp is in mounting groove 5, the LGP upper end is fastened in the mounting groove 5, incidence surface 31 in the photic zone is close to LED lamp 1, and the backboard 6 in the bracing frame is close on reflector layer 2 tops in the LGP, and the reflective surface 32 in reflector layer 2 and the photic zone closely combines; Design has the LED lamp 1 more than 2 in mounting groove 5; Described fin 4, mounting groove 5 and backboard 6 are overall shaped into one; Exiting surface 33 in the photic zone is rectangle; Reflective surface 32 in the described photic zone is parabolic shape, and reflector layer 2 also is parabolic shape with reflective surface 32 corresponding faces that closely combine in the photic zone.
