Abstract
The utility model provides a double-surface light emitting plate, comprising a light guiding plate with two light-permeable surfaces. One surface of the light guiding plate is provided with reflective elements and is adhered and connected with a light-permeable panel. Compared with the prior art, the double-surface light emitting plate almost has no dead angle for light radiation, and achieves relatively high light source utilization rate, energy-saving effect, long service lifetime and strong decorative effect.
Description
Technical field:
The invention belongs to lighting field, relate in particular to a kind of double-side plate.
Background technology:
Under the prior art condition, the LED flat head lamp comprises a light guide panel, the subsidiary light emitting source of frame is encapsulated on the limit of light guide panel, the LGP and one that light guide panel comprises one one printing opacities is the light penetrating panel of transparent surface bonding connection with it, be distributed with reflective spot or Reflect light line on the non-transparent surface of LGP, the light that light source sends, after reflective spot through distributing on the LGP or the reflection of Reflect light line and the scattering, penetrate via light penetrating panel, the light that light emitting source is sent changes direction, realizes that line source converts the area source towards irradiation object to.
Prior art has following defective:
1. because light shines out through an area source, so the dead angle of light irradiation is bigger, relatively poor back to a light of irradiation object;
2. the light that sends of light emitting source shines out through a face, and the light source utilization rate is lower.
Summary of the invention:
Big for solving above LED flat head lamp lighting dead angle, the problem that the light source utilization rate is low, the utility model provides a kind of double-side plate, and this double-side plate lighting dead angle is little, light source utilization rate height.
The technological means that this double-side plate technical solution problem is adopted is: this double-side plate comprises a LGP, and the one side of LGP is distributed with reflective key element, described LGP two sides printing opacity, and the one side of the reflective key element that distributes also bonding connection has a light penetrating panel.
Preferably, described reflective key element is a reflective spot.
Optionally, described reflective key element is a Reflect light line.
Preferably, described light penetrating panel is glass, transparent organic material or natural printing opacity stone.
Preferably, described reflective spot or Reflect light line are that silk-screen is on LGP.
Optionally, described reflective spot or Reflect light line are that engraving is on LGP.
Preferably, described light emitting source is the LED particle.
Optionally, described light emitting source is the LED bar.
Preferably, the different luminescent spectrums of the LED particle of described light emitting source or LED strip adoption.
Double-side plate of the present utility model compared with prior art has following beneficial effect:
1. because light is two faces that pass through LGP to be shone out, so the light irradiation does not almost have the dead angle;
2. the light that sends of light emitting source is that two faces through LGP shine out, and the light source utilization rate is than higher.
Description of drawings:
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of double-side plate;
Fig. 2 is the another kind of schematic diagram of the light guide panel of double-side plate;
Fig. 3 is the rip cutting figure of double-side plate;
The specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Figure 1-3, the light guide panel of this double-side plate (1) comprises that a LGP (2) reaches two light penetrating panels (3) of two face difference bonding connection with it, be distributed with reflective key element (4) on the face of LGP (2), the subsidiary light emitting source (6) of frame (5) is encapsulated on the limit of light guide panel (1).Reflective key element can be reflective spot (7), it also can be Reflect light line (8), light penetrating panel (3) can be a glass, also can be other transparent materials, reflective spot (7) or Reflect light line (8) can be that engraving is on LGP (2), also can be silk-screen on LGP (2), LGP (2) two sides printing opacity.Light emitting source (6) adopts LED particle or LED bar, and LED particle or LED bar can adopt different luminescent spectrums.
Light emitting source (6) is encapsulated on the limit of light guide panel (1), the light that light emitting source (6) sends, after the reflection and scattering of last reflective spot (7) that distributes of LGP (2) or Reflect light line (8), passing LGP (2) and light penetrating panel (3) penetrates, the light that light emitting source (6) is sent changes direction, realizes that line source converts the area source towards irradiation object to.Because being two area sources of process LGP (2), light shines out, so the light irradiation does not almost have the dead angle; In addition, the light that light emitting source (6) sends reflects through two LGPs (2) or scatters out, and the light source utilization rate is than higher.
Claims (9)
1. a double-side plate is characterized in that the subsidiary light emitting source of frame is encapsulated on the limit of LGP, and any one side of LGP is distributed with reflective key element, and there is the two sides light penetrating panel on the two sides of LGP bonding connection respectively.
2. according to the described double-side plate of claim 1, it is characterized in that described reflective key element is a reflective spot.
3. according to the described double-side plate of claim 1, it is characterized in that described reflective key element is a Reflect light line.
