Abstract
The invention relates to a surface light source device and method for manufacturing the same, which belongs to the technical field of decorative lighting. The surface light source device comprises a point light source and two strip transparent boards that are overlapped with each other or separated at certain distance. The strip is formed by a plurality of parallel strip grooves. The strip directions on two strip transparent boards are crossed into angles. The device causes the light ray to be continuous and uniform with good visual effect, and has the advantages of simple structure, convenient production and low cost.
Description
Technical field
The present invention relates to a kind of LED planar light source device and preparation method thereof, belong to the lighting decoration controlled technical field.
Background technology
At present, existing lighting is when adopting the LED spot light, and these spot light light are discontinuous, inhomogeneous, and illumination or decorative effect are poor; And be easy to generate dazzle, cause uncomfortable, eye fatigue, eyesight descends.Existing led illuminating lamp has employing and addresses the aforementioned drawbacks in the mode of LGP both sides notes light, but the light fixture light efficiency is very low, and energy-saving effect is poor.Therefore need a kind of technology that light is become continuously evenly, reduce the generation of dazzle, and cost is relatively low.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the invention provides a kind of planar light source device with practical value, this device not only can become light continuously evenly, and good visual effect, and have simple in structure, implement convenient and advantage with low cost.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of planar light source device comprises spot light, two striped light-passing boards; It is characterized in that described two striped light-passing boards are overlapped or separated by a distance, described striped is formed by many strip grooves that are parallel to each other, and the stripe direction on two striped light-passing boards intersects angle.
As preferred implementation, the stripe direction of two light-passing boards is vertical mutually; Strip groove all is arranged on backlight one side; Two striped light-passing boards can be surface plate, spherical plate or cambered plate.
The present invention converts spot light to area source by two striped light-passing boards, makes light become soft even, good visual effect, and have advantage simple in structure, easy to make and with low cost.
Description of drawings
Fig. 1 is the structural representation that spot light is converted to planar light source device of the present invention.
Fig. 2 is the decomposing schematic representation of device of the present invention.
Fig. 3 becomes spot light for the present invention the principle schematic of area source.
Mark 1 is the striped light-passing board among the figure, and 2 is the striped light-passing board, 3 expression spot lights, 4 expression Line of light, the planar light of 5 expressions.
The specific embodiment
The present invention is described in detail below in conjunction with drawings and Examples.
Referring to Fig. 1 and Fig. 2, two striped light-passing boards of present embodiment employing overlap each other and constitute the device that spot light is converted into to area source together.In actual applications, both also can at intervals place, and are fixed up with support or panel around two light-passing boards.Two striped light-passing boards can be the identical surface plate of size as present embodiment, can a plate be surface plate also, and the another one plate is spherical plate or cambered plate, can two planks all be spherical plate or cambered plate also.Striped on two striped light-passing boards is formed by many strip grooves that are parallel to each other, and stripe direction is vertical mutually or intersect certain angle.As preferred implementation, the stripe direction of two plates is preferably vertical, and like this, light conversion efficiency is the highest.
Referring to Fig. 3, spot light 3 does not promptly have the incident of groove one side from the smooth one side of striped light-passing board 1, converts point-like light 3 to Line of light 4 by striped light-passing board 1, Line of light 4 is converted to planar light 5 by striped light-passing board 2 again.Striped light-passing board 1 directly overlays on the spot light, and light-passing board 2 overlays on the light-passing board 1, and all strip grooves all are arranged on backlight one side.
Claims (4)
1. planar light source device, comprise spot light and two striped light-passing boards, it is characterized in that described two striped light-passing boards are overlapped or separated by a distance, described striped is formed by many strip grooves that are parallel to each other, and the stripe direction on two striped light-passing boards intersects angle.
2. device according to claim 1 is characterized in that the stripe direction of described two light-passing boards is vertical mutually.
