Specific embodiment
The present invention will be further described in detail below with reference to the embodiments, following embodiment be explanation of the invention and
The invention is not limited to following embodiments.
A kind of Windowsill lamp reflector element, as shown in Figure 1, 2, including reflector 1 and LED light source, the reflector 1 are song
Face, the curved interior surface are the reflecting surface of light reflection, and the shape of the cross section of the inner surface of the curved surface is parabola, institute
The light for stating the sending of LED light source 2 is reflected in the reflecting surface, and the center of the LED light source 2 is cutd open positioned at reflecting surface
The parabolical focal point in face, and the light-emitting surface center of the LED light source 2 be located at the parabolical bottom boundary of reflecting surface section just on
At side distance a, the LED light source and the parabolical distance from top of reflecting surface section are b.Here, passing through, a, b have determined light source
The relative position at center and reflector, and a, b make light source center be located at the parabolical focal point of the face A section.In this way, regardless of
The size of reflector is how many, as long as there is these three elements, so that it may determine the position of LED light source, a, b are with reflector
What size was changed, the only relative position that can determine that light source center and reflector a, b, along with a, b make in light source
The heart is located at the specific location that the face the A parabolical focal point of section is assured that LED light source.The purpose being arranged in this way is lain also in only
The direction of LED light source optical axis is determined, then, the reflection light of all light is parallel.
It needs to declare, parabolical focus is determining in fact, it is contemplated that complete parabola is the two of an endless
Secondary curve, and actual reflector be it is time-limited, in order to limit the size of reflector, therefore, given in entire scheme a and
Two constraint conditions of b, then cooperate the focus of reflector, i.e., it can limit shape and the position in reflector main optical face.Also
It is to say, the value of a, b define the shape in reflector main optical face, and the value of a, b are to depend on reflector overall dimensions in fact
Target value.
By above embodiments, referring to as shown in Figure 1, the position of LED light source is constant, the optical axis direction of LED light source can be sent out
Changing, it is assumed that when LED light source optical axis direction and vertical direction angle are α, β is angle of the preceding section of reflection to light source center,
In this way, all light in the angle β are used effectively, γ is the angle of source plane and vertical direction, all in the angle γ
Light is not utilized directly by reflector.And can control the utilization rate of light by adjusting the value of γ and β, β takes larger can be improved
Whole light efficiency, and hot spot effect will not be generated and be significantly affected.That is, after the value and focus of a, b are given, reflector
Shape just secure, then β's also determines that, then to determine that the value of α, the value of usual α are entire to reflect closer to β/2
The light efficiency of device is higher, just has more light to meet the expection such as Fig. 2, projects from reflector alignment, and remaining light can then damage
It loses；The emergent ray of LED light source covers half space, and in the π angular region of optical axis direction, the light in the angle γ is without anti-
Emitter will necessarily lose, at this point, the light of β is fully used, the light in remaining π-alpha-beta angle be also lose, however
Loss number depend on b value, b is bigger, and this angle is smaller, then the energy lost is fewer, as b=∞, this angle β be 0,
Thus when giving the value of b, under the constraint condition for meeting overall dimensions, the value of b takes larger, so that it may improve light
Effect.
The design of the Windowsill lamp reflector element of the present embodiment is that parabolical optical characteristics is utilized, and can be controlled in this way
The exit direction of light processed, and then improve the utilization rate of LED light source takes coordinate system as shown in figure 3, at this moment parabolical equation
For y2=2px.The coordinate of postulated point M is (X0, y0), then the equation of normal MN isY=0 is enabled, just
To the coordinate of normal and the focus N of x-axisSoAgain by parabolic
Known to the definition of line: | FM | equal to the distance of M to directrix, thereforeSo | FM |=| FN |, it is hereby achieved thatThe light for passing through focal point, after parabolic reflective, reflection light and parabolical symmetry axis are flat
Row.Therefore, the center of the LED light source 2 is located at the parabolical focal point of reflecting surface section, and the hair of the LED light source 2
Smooth surface center is located at right above the parabolical bottom boundary of reflecting surface section at distance a, and the LED light source and reflecting surface section are thrown
The distance from top of object line is b, in this way, can increase the utilization rate of LED light source, a, b have determined phase of the light source center with reflector
To position, a, b make light source center be located at the parabolical focal point of the face A section.
In order to verify to reflector, the present embodiment carries out effect emulation using ray-tracing software TracePro, first
Model of the receiver board of one 200mm*2000mm as practical ceiling is first set, and the place of 1000mm is placed below ceiling
Reflector is mixed suitable light source and is emulated, as a result as shown in Figure 4,5.Fig. 4,5 are ceiling illumination figures, it can be seen that light
Spot straight line elongated in shape, two sides dead line is clear, is better than general Windowsill lamp lens effect.
Fig. 6-Fig. 7 is the light distribution curve under different coordinates, it can be seen that angle is smaller in one direction for emergent ray,
At 3 degree or so, therefore this direction necessarily has clearly hot spot dead line；Another orientation angle very greatly at 80 degree or so, this
A direction hot spot is longer, therefore finally obtained is the strip hot spot for having clear dead line, meets the use need of Windowsill lamp
It asks.In addition, hot spot is then without dividing if can guarantee light source itself without color separation (preferable light source being selected, such as the light source of CREE)
Color (reflection is not in color separation phenomenon), this is that general Windowsill lamp lens can not accomplish (general Windowsill lamp lens color separation phenomenon
Seriously).
It, can be according to the actual demand of user in other embodiments, thus it is possible to vary as a result parabolical size can change
Light efficiency, reflector size and light distribution are as a result, because comprehensively considering these factors when designing.
In all embodiments, the reflector is using with reflector made of ductile material.Pass through ductility
Material, reflector can be stretched, in this way, if it is not being able to satisfy user needs when a Windowsill lamp reflector element
It asks, but places two Windowsill lamp reflector elements and will result in the waste of material, since reflector has ductility, thus
Reflector can be stretched, so that length or width become larger, reach the demand of client.
In other embodiments, the LED light source 2 includes at least a LED；When LED is more, plurality of LEDs is successively
It is arranged on the straight line；When LED is more, plurality of LEDs is the LED of same color or the LED of different colours.Pass through difference
The LED of color can do RGB light mixing.
