Therefore, one of following light source that the LED lighting source is most interested in as people, its direct target will be replace incandescent and fluorescent tube.MITI of Japan is called this " illuminate Japan project ", promptly is incandescent lamp and the fluorescent lamp that substitutes half, annual saving is equivalent to the energy of 6,000,000,000 crude oil, has great economic benefit and social benefit.
The utility model content
In order to overcome the defective of lighting sources such as existing incandescent lamp and fluorescent tube, the utility model provides a kind of Diffusion Type Led-based Lighting, this light source is except that the characteristics that have the LED cold light source fully, introduced side leaded light technology backlight, it can regulate the emission state of LED light beam, make originally and handle by the leaded light of LGP for the light source of point-like, change area source into, unconsciously dazzling when making people see light source, play the effect of illumination again, have more the LED long-life, low in power consumption, and can be at area, shape, aspects such as direction change on demand, for the use of led light source provides more wide space.
In order to reach this purpose; the utility model provides following technical scheme; a kind of Diffusion Type Led-based Lighting; this lighting source has comprised efficient and energy-conservation superbright LED illuminating source; the high light-conductive rate of light-conductive rate＞90% and high all LGPs of photosensitiveness; the highly reflecting films of reflecting rate 95%; directional transmissions cover and diffuser; superbright LED illuminating source is placed on the side of LGP; reflective membrane is placed on the one side that LGP has line; LGP is not placed the side of LED also can paste reflective membrane in case light leak; diffuser is placed on the front of LGP; outside these members, place directional transmissions cover and diffuser with protective effect; outer field directional transmissions cover of light source or scattering cover; make the light-emitting area of light source present uniform directional beam; this light source can change the luminescence emissions direction of LED, has widened the light-emitting area and the shape of light source.
Described superbright LED illuminating source can be a kind of efficient and energy-conservation superbright LED luminescence chip, also can be a kind of superbright LED encapsulation lamp.
The shape of described lighting source can be rectangle, circle or other shape.
Described superbright LED illuminating source can be placed on a side, two sides or all sides that LGP forms.
The back side of described LGP is provided with can pass through the laser rag, process rag, be printed as line or be injection molded into sags and crests or the tongue and groove that all light technology of line forms.
The utility model mainly possesses following advantage: this Diffusion Type Led-based Lighting combines superbright led light source technology and side backlight light-guiding technology; can change the luminescence emissions direction of LED; the light-emitting area and the shape of light source have been widened greatly; formed various uses; different lighting source; it is fast that led light source is lighted the time; electromagnetic-radiation-free; save the energy; long service life; simultaneously, resistant to elevated temperatures light-guide material is fit to use in multiple place, can make the soften of light through the led light source of LGP diffusion; the uniformity is well improved and is promoted; can the better protection vision, for the use of light source of new generation provides more wide space.
Description of drawings
Fig. 1 is the exemplary block diagram of the utility model light source.
Fig. 2 is an operation principle schematic diagram of the present utility model.
Fig. 3 is the structural representation of the utility model rectangle lighting source.
Fig. 4 is the structural representation of the utility model circular illumination light source.
The specific embodiment
The typical structure of the utility model light source as shown in Figure 1, main member is: highly reflecting films 1, reverse side has the LGP 2 of dimpled grain, superbright LED illuminating source 3, directional transmissions cover 4, diffuser 5, the highly reflecting films that the utility model light source relates to, its full light reflecting rate 〉=95% is moulded fat by special-purpose optics and is made the silver-colored luminescent material of the high reflection of surperficial lining, can make the loss of light reach few.The LGP that the utility model light source relates to is moulded the fat material by the optics of light-conductive rate 〉=90% and is made, and can or be machined into different shape by injection moulding.Equal photoconduction on the LGP can or be injection molded into line with laser engraving, mechanical engraving, serigraphy to line.The shape of LGP can be bar-shaped, spherical, planar or other geometry that needs.Its area can be several square centimeters or several thousand square centimeters.
