Abstract
The utility model provides a lighting device, includes light guide plate, reflecting plate and light source, is equipped with on the light guide plate and goes out plain noodles, plane of reflection and at least one light incident surface, and the relative plane of reflection of reflecting plate sets up, and the relative light incident surface of light source sets up its characterized in that: the light incident surface is a curved surface or an inclined surface. The utility model discloses a lighting device designs the incident plane of light guide plate for curved surface or inclined plane, makes the light that the light source sent change the propagation path of light under the effect of curved surface or inclined plane form incident plane, can evenly throw on arbitrary position of light guide plate, and the play plain noodles of following the light guide plate at last jets out again, and whole light guide plate is luminous even, does not have the dark space. In addition, the number of light sources is not increased, the cost is saved, and the power consumption is lower.
Description
Technical field:
The utility model relates to lighting, advertising lamp box, direction board case and the ultra-thin frame of a kind of lighting device and application thereof.
Background technology:
Existing lighting device, tabular lighting as shown in Figure 1, the lamp 02 that generally comprises LGP 01 and be located at LGP 01 periphery, a side relative with lamp 02 on the LGP 01 forms plane of light incidence 011, and plane of light incidence 011 is generally a vertical plane.There is following defective in this lighting device: be perpendicular because of the plane of incidence 1,, so being parallel projection, the light overwhelming majority that power lights is sent advances in the LGP, these parallel light of injecting are because can not be reflected by the reflecting surface at the LGP back side, and can there be certain light loss in the parallel light of injecting in the LGP in communication process, so can cause the lateral location of close lamp on the LGP brighter, then there is the dark space in the LGP centre position, the whole non-uniform light of LGP; 2, in order to eliminate or to reduce the dark space, common way is the power that increases lamp, yet does like this and can increase cost, and the power consumption height, does not meet low-carbon economy now, so need make improvements it.
Summary of the invention:
A purpose of the present utility model is to provide a kind of uniform lighting device simple in structure, luminous.
A kind of lighting device, comprise LGP, reflecting plate and light source, LGP is provided with exiting surface, reflecting surface and at least one plane of light incidence, the relative reflecting surface setting of reflecting plate, the relative plane of light incidence setting of light source is characterized in that: described plane of light incidence is a curved surface or inclined-plane.
The lighting device of the utility model, the plane of incidence of LGP is designed to curved surface or inclined-plane, the light that light source is sent changes the propagation path of light under the effect of the curved surface or the inclined plane shape plane of incidence, can evenly be incident upon on arbitrary position of LGP, last penetrate from the exiting surface of LGP again, whole LGP is luminous evenly, does not have the dark space.In addition, do not increase quantity of light source, save cost, power consumption is lower.
Described plane of light incidence is an inner sunken face, can change the propagation path of light, light evenly is incident upon on arbitrary position of LGP, and shoots out from the exiting surface of LGP.
Described plane of light incidence is an outer convex surface, can change the propagation path of light, light evenly is incident upon on arbitrary position of LGP, and shoots out from the exiting surface of LGP.
Described plane of light incidence is an accordion curved surface or an inclined-plane, can change the propagation path of light, light evenly is incident upon on arbitrary position of LGP, and shoots out from the exiting surface of LGP.
Described reflecting plate is a diffuse reflector, makes the light that enters from the LGP plane of incidence can further improve the luminous uniformity of LGP evenly to all directions reflection of LGP communication process.
A kind of LED lighting is characterized in that having used above-mentioned described lighting device, and described light source is LED lamp, fluorescent lamp, electrodeless lamp or energy-saving bulb.
A kind of advertising lamp box is characterized in that having used above-mentioned described lighting device.
A kind of direction board case is characterized in that having used above-mentioned described lighting device.
A kind of ultra-thin frame is characterized in that having used above-mentioned described lighting device.

The specific embodiment:
Embodiment one: as Fig. 2, shown in Figure 3, a kind of lighting device, especially a kind of tabular lighting, comprise LGP 1, reflecting plate 3 and light source 2, LGP 1 is provided with exiting surface 12, reflecting surface 13 and at least one plane of light incidence 11, reflecting plate 3 is the diffuse reflector that relative reflecting surface 13 is provided with, and described light source 2 relative planes of light incidence 11 are provided with, and this plane of light incidence 11 is an outer convex surface.
A kind of lighting has used described lighting device, and wherein said light source is LED lamp, fluorescent lamp, electrodeless lamp or energy-saving bulb.
A kind of advertising lamp box has used described lighting device.
A kind of direction board case has used described lighting device.
A kind of ultra-thin frame has used described lighting device.
Embodiment two: as shown in Figure 4, be with embodiment one difference that described plane of light incidence 11 is an inner sunken face.
Embodiment three: as shown in Figure 5, be with embodiment one difference that described plane of light incidence 11 is an accordion curved surface.
Embodiment four: as shown in Figure 6, be with embodiment one difference that described plane of light incidence 11 is an inclined-plane.
The foregoing description is a better embodiment of the present utility model; but embodiment of the present utility model is not limited thereto; other are any not to deviate from change, the modification done under spiritual essence of the present utility model and the principle, substitute, combination, simplify; be the substitute mode of equivalence, be included within the protection domain of the present utility model.
