Abstract
This invention discloses a lightning surface light source which consists of curved plane and lighting slab. The technical scheme includes lighting slab, lighting resource, electricity source and curved plane. The light pattern is set on the lighting slab, the lighting resource which is set beside the lighting slab connects to the electricity source and the light comes from the side. The reflecting plane is concave, arch or prismatic. The concave faces one side of the two shiny surfaces of the lighting slab and the reflecting light ejects from the other side of the lighting slab. The merits of the invention lie in replacing the current attaching plane reflection slab with the curved plane making the light from one side of the lighting slab assemble to the lighting area outside the lighting slab so as to improve the lightness. Meanwhile, with no reflection slab the lighting slab is glittering, bright and beautiful. Besides, it is green and energy-saving with LED as the source of the lighting slab.
Description
Technical field
The present invention relates to a kind of area source that is used to throw light on that constitutes by curved-surface reflection side and LGP.
Background technology
Present LGP area source, reflecting plate that is adopted or reflecting surface all are the planes, and are attached at the back side of LGP.When the LGP area source is used to throw light on, the problem that luminous dispersion and luminous intensity are not concentrated will occur, and make LGP lose sparkling and crystal-clear bright characteristic, influenced attractive in appearance.Can not improve illumination effectively and increase the LGP area.Especially when adopting the LED group for the LGP incident light source, because the encapsulation volume of low-power LED has limited the arranging density that LED organizes cheaply, also just limited the incident light intensity, the requirement of luminous degree of converging was just higher when LGP was used to throw light on.
And at present the larger area LGP uses fluorescent tube as light emitting source more, can have " stroboscopic " when being used to throw light on, exchanges harm such as radiation and include harmful substances " mercury ".
Summary of the invention
At the deficiency of above-mentioned existing LGP area source when being used to throw light on, the present invention has adopted the curved surface reflector or the curved surface reflective surface of non-sticking type, makes the LGP surface source luminescence more concentrated, and outward appearance is more graceful.And the present invention adopts the light emitting source of LED group as LGP, healthy environment friendly energy-conservation.
The present invention is achieved in that a kind of area source that is used to throw light on that is made of curved-surface reflection side and LGP, includes LGP, light source, power supply and curved-surface reflection side.Wherein, described LGP is provided with the leaded light pattern; Described light source is connected in described power supply; Described light source is arranged at described LGP side, and by its side incident; Described curved-surface reflection side is concave surface, arc or prismatic; The concave surface of described curved-surface reflection side is towards LGP two light-emitting areas one side, and reflection ray penetrates from the another side of LGP light-emitting area.
Wherein, described curved-surface reflection side is concave surface, arc or prismatic, is specially: part ball face, part ellipsoidal surface, the part face of cylinder, part elliptic cylinder, part prismatic surface or U-shaped are constituted or are spliced by a plurality of individualities by single individuality.Described curved-surface reflection side has high reflectance towards the concave surface of LGP one side, and reflection ray penetrates by LGP is positive.The focus of described curved-surface reflection side or reverberation convergent point should be positioned at the zone of distance more than 10 centimetres outside the LGP front.
Wherein, described light source is the LED group.Described LED group is for one or more, and wherein all LED are parallel with one another and be connected in described power supply, and described power supply is a constant-voltage DC source.
In addition, this area source also includes LED group cladding plate, and this cladding plate is organized semi-surrounding with LED, makes the light of LED group emission inject described LGP fully.
The present invention has replaced the sticking type plane reflector that present LGP area source adopts with curved-surface reflection side, makes the light of the LGP back side one side can reflect the field of illumination that converges in outside the LGP front, improves brightness of illumination.Simultaneously, sparkling and crystal-clear bright because LGP is not attaching reflecting plate, have aesthetic feeling.Adopt the incident light source of LED group, healthy environment friendly energy-conservation as LGP.LED in the LED group is connected in parallel and adopts constant-voltage DC source, has improved the reliability of equipment effectively.

Fig. 2 is the lateral plan of same embodiment among Fig. 1;
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention.
Fig. 1 is a decomposition texture schematic diagram of the present invention.Shown in the figure is that a LGP is rectangular embodiments of the invention, adopts the curved-surface reflection side of curved circular cylinder, and its pattern backlight is a line graph, one-sided light inlet.
As shown in Figure 1, the present invention includes LGP 11, LGP is provided with leaded light pattern 12, and LED organizes the 13 side incident raies from LGP, the curved-surface reflection side 14 of curved circular cylinder, power supply 15 and pcb board 16.When the present invention worked, 13 made two-sided area source of the luminous formation of LGP from LGP side incident ray.LGP is reflected to the light of camber reflection surface launching, converges at the field of illumination outside the LGP front, realizes the function of illumination.
LGP 11 can form different shape, and the leaded light pattern can be point-like or wire, and light source 13 can also carry out half coating makes more light enter LGP from the side.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those skilled in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
