Abstract
The utility model discloses LED point light source and area light source switching equipment, which comprises two stripe light transmitting plates. The LED point light source and area light source switching equipment is characterized in that the two stripe light transmitting plates are overlapped and arrayed mutually and are abutted mutually or spaced at a certain distance, stripes are formed by a plurality of mutually parallel strip-shaped grooves, stripe directions of the two stripe light transmitting plates are crossed at a certain angle, and the strip-shaped grooves are all disposed on one side of a backlight source. The LED point light source and area light source switching equipment has the advantages that point light sources are switched into area light sources by the aid of the two stripe light transmitting plates so that light is soft and uniform and vision effect is fine, and further, the LED point light source and area light source switching equipment is simple in structure, convenient in manufacturing and low in cost.
Description
[technical field]
The utility model relates to a kind of equipment that the LED spot light is converted to area source.
[background technology]
At present, present lighting is when adopting the LED spot light, and these spot light light are discontinuous, inhomogeneous, illumination or decorative effect are poor, and are easy to generate dazzle, cause eye fatigue, watch the LED spot light attentively, cause eyesight to descend when serious easily as the workers with long time of production line.
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 on the market, reduce the generation of dazzle, and the relatively low equipment of cost.
[utility model content]
The purpose of this utility model is at above-mentioned the deficiencies in the prior art part, a kind of LED spot light and area source conversion equipment are provided, this equipment not only can become light continuously evenly, good visual effect, and have advantage simple in structure, easy to make and with low cost.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED spot light and area source conversion equipment, comprise two striped light-passing boards, it is characterized in that, described two overlapped arrangements of striped light-passing board, and mutually near 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 certain angle.
According to the utility model of said structure, its feature is that also the stripe direction of two striped light-passing boards is vertical mutually.
According to the utility model of said structure, its feature is that also described strip groove all is arranged on backlight one side.
According to the utility model of said structure, its feature is that also two striped light-passing boards can be surface plate, spherical plate or cambered plate.
According to the utility model of said structure, its beneficial effect is that the utility model is by two striped light-passing boards, convert spot light to area source, make light become soft even, good visual effect, and have advantage simple in structure, easy to make and with low cost.
[description of drawings]
Below in conjunction with drawings and the embodiments the utility model is explained detailedly.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a decomposing schematic representation of the present utility model.
Fig. 3 is a principle schematic of the present utility model.
Among the figure, 11, the striped light-passing board; 13, spot light; 14, Line of light; 15, planar light.
[specific embodiment]
As Fig. 1 and Fig. 2, two striped light-passing boards 11 of present embodiment employing overlap each other and constitute the device that spot light 13 is become area source together, in actual applications, both also can at intervals install, and are fixed up with support or panel around two light-passing boards 11.
Two striped light-passing boards 11 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 11 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 13 is from the smooth one side of striped light-passing board 11, promptly there is not the incident of groove one side, convert point-like light 13 to Line of light 14 by striped light-passing board 11, again Line of light 14 is converted to planar light 15 by striped light-passing board 11, striped light-passing board 11 directly overlays on the spot light, and two striped light-passing boards 11 are stacked together, and all strip grooves all are arranged on backlight one side.
Only the part of the utility model preferred embodiment shown in the utility model the foregoing description and the accompanying drawing; can not limit to the utility model with this; under the condition that does not break away from the utility model marrow, any change that those skilled in the art did all belongs to protection domain of the present utility model.
