Detailed Description Of The Invention
In the following description, shown specific embodiment of the present invention with reference to accompanying drawing and by description.Should be appreciated that, can use other embodiment, can make structure and other variation to it without departing from the present invention.Moreover, the use that can mutually combine of the various aspects of each embodiment and each embodiment.Therefore, accompanying drawing and detailed description will be counted as descriptive, rather than restrictive.Identity element in each accompanying drawing is by same reference numeral.
The present invention relates to a light reflecting cover, it is used for the emission light that light source produces.According to an embodiment, light reflecting cover is the cavity of a trapeziform trapezoidal shape (trapezoidal), and an end is an optical receiving end, and the other end is a light output end.Cavity inner wall is reflective, has a plurality of stratum or conduit to be used for the light reflection is gone out from output.
Referring now to Fig. 1 and 2, Fig. 1 is the vertical view of a light reflecting cover 100 of first embodiment of the invention, and Fig. 2 is the bottom view of light reflecting cover 100.Light reflecting cover 100 has plate 104 behind the header board 102,, first side plate 106 and second side plate 108.Header board 102, back plate 104, first side plate 106 and second side plate 108 can be called " plate " together.Each plate outside its bottom angle is tilted to, forms one four lateral opening chamber in that light reflecting cover 100 is inner from the top of light reflecting cover 100, vestibule from the top to the bottom flare.The inner face of each plate normally reflects, thereby forms a reflection vestibule in light reflecting cover.According to an embodiment, each plate only some inner face reflects, or at least a portion inner face of vestibule reflects.The lateral alignment of header board 102 is parallel to the lateral alignment of back plate 104 usually.Second angle that first angle that first side plate 106 and header board 102 form and second side plate 108 and header board 102 form normally equates.Equally, the third angle degree of first side plate 106 and back plate 104 formation and second side plate 108 also equate usually with the 4th angle that back plate 104 forms.So light reflecting cover has the trapezoidal trapeziform frustum of a pyramid shape of a truncation.
The light reflecting cover of described embodiment is the shape of the trapezoidal pyramid of quadrangle truncated cone or truncation normally.So according to embodiment, the lateral cross section layer of light reflecting cover is a quadrangle or a trapezoidal shape.
The plate of light reflecting cover 100 forms a square or four-sided openings 109 usually at the top of light reflecting cover 100, and forms a bigger isosceles trapezoid opening 110 (Fig. 2) in the bottom of light reflecting cover.In use, the top of light reflecting cover 100 is placed and covers on light source top, and light is launched or reflected away from the trapezoid-shaped openings of reflector 100.
It is the LED illumination that of light reflecting cover practices, and the structure of light reflecting cover can be particularly suitable for the LED illumination.But, light reflecting cover is not subject to the LED illumination and uses, also can be used for other types of illumination, as incandescent lamp (incandescent), fluorescent lamp (fluorescent), high-voltage gas discharging light (high intensity discharge), low-pressure sodium lamp (low pressuresodium), solar energy or any other types of illumination.Light reflecting cover embodiment can be used for any illumination and use, as lamp, street lamp, park illumination, portable lighting, room lighting, outdoor lighting, building lighting, decorative lighting, emergency lighting and other suitable applications.
With reference to Fig. 2, along the inner face of plate, the plate inwall has circumference stratum 112.Stratum comprises that a plurality of adjacent oncus (ridge) extend to the bottom from the top of each plate of light reflecting cover 100.Stratum 112 constitutes a ribbed surface, and each stratum 112 forms one four side ring shape oncus in the periphery of inner wall of light reflecting cover 100 plates.So, term " oncus " and " stratum " trans-substitution use mutually.The shape of stratum 112 can be described at an easy rate with reference to Fig. 3 A and 3B.According to an embodiment, the inner surface of light reflecting cover 100 is inferior light clad cans of exasperate, uniformity of light in order to strengthen.But the clad can of other effects also can be used on the inner surface, as the requirement of particular implementation institute.According to an embodiment, reflecting surface comprises vacuum deposited aluminum.According to another embodiment, reflecting surface comprises vacuum-deposited silver.According to another embodiment, reflecting surface can comprise aluminium, silver or an aluminium silver compound of implementing according to any appropriate method.
Fig. 3 A is the sectional view of the light reflecting cover that shows along line A in first embodiment of the present invention Fig. 1.In Fig. 3 A, can see a cross section of first side plate 106 and second side plate 108.In the sectional view shown in Fig. 3 A, can be easy to see the shape of each stratum 112 of on first side plate 106 and second side plate 108, seeing.In described embodiment, there is a convex arc in each stratum 112, and is crooked away from plate.The curved shape of different stratum, height and the degree of depth may be different.Light reflecting cover 100 has a top 114 and a bottom 116.
Fig. 3 B is the sectional view of the light reflecting cover that shows along line B in Fig. 2.In Fig. 3 B, can see a cross section of header board 102 and back plate 104.In the sectional view shown in Fig. 3 B, can see the shape of each stratum of header board 102 and back plate 104.
Though each stratum 112 has identical height usually, can change stratum's height to obtain the light output of expectation.In addition, the shape of arc radius value and arc can be different in different stratum, from about 2 millimeters to about 40 millimeters.In an embodiment, the arc radius arrives in about 12 millimeters scope at about 3 millimeters.Although the excursion of example is provided, changing value may depend on output uniformity, reflector size and the light-source brightness of expectation.Be appreciated that isolated value also may be according to the shape and concrete throw light on and use different and different of the light reflecting cover that uses.In addition, though in accompanying drawing, described a specific arc radius, can use other suitable arc radius.
The selection of arc radius value will be considered the balance between light loss consumption (optical loss) and the uniformity (uniformity value).Radius value is more little, and uniformity is good more, and the light loss of light reflecting cover consumption is then big more, is that light when light emitted is reflected by the light in the reflective optical system during with the interaction of each stratum and diffraction causes because light loss consumes to small part.But, because the amount of the light loss that reflection and diffraction cause consumption and little is an acceptable, because the growth of output uniformity of light is sizable.In an embodiment, the light loss consumption approximately be overall optical power 3% or less than 3%.
According to one embodiment of the present of invention, the arc radius arrives in about 15 millimeters scope at one about 8 millimeters.All different from bottom to top layer arc radius.Also can use other shape in the stratum, as a combined shaped of other curve shape or curve and straight line and angle.
