Specific embodiment
As shown in Figure 1 to Figure 3, the present embodiment provides a kind of reflectors, including the first reflective surface 5, the second reflective surface 6 and
Three reflective surfaces 7, first reflective surface 5, the second reflective surface 6 and third reflective surface 7 are successively smoothly connected, and are all made of curved surface knot
Structure, for first reflective surface 5 close to metope 1, the third reflective surface 7 is farthest apart from metope 1, and the light of light source 3 is anti-from second
When the top position of smooth surface 6 is irradiated down to reflector 2, light is equably reflexed to metope 1 by the reflector 2.
Referring to Figures 1 and 2, when being applied to reflector 2 to wash wall illumination, the reflector 2 is horizontally arranged at the attached of metope 1
Closely, specifically, first reflective surface 5 is nearest at a distance from metope 1, is secondly the second reflective surface 6, the third reflective surface 7
It is farthest apart from metope.For the present embodiment by carrying out asymmetrical sectional design to reflector 2, the light source 3 is mounted on second
The top position of reflective surface 6, the light of light source 3 are aimed downwardly to reflector 2, and reflector 2 carries out secondary distribution to light, due to
The different light of progress of each reflective surface to light distributes, and more reasonably distribution is irradiated to the light at 1 bottom of metope to top
Line avoids passing through the brightness irregularities that lens light distribution is uneven, on metope 1, out so that light be made uniformly to expose on metope 1
Show hot spot, caused dazzle, reduces illumination comfort level and illuminating effect.In addition, using lens on light line using reflector ratio
Utilization rate it is higher, improve light utilization.
Specifically, as described in Figure 3 using the wall lamp of the reflector 2 of the present embodiment, the light source 3 is mountable in light source board
On, the surface of the second reflective surface 6 is arranged in the light source board, since reflector 2 is made using highly reflective material, to keep away
Exempt from dust to fall on reflector 2, increases by one layer of glass 4 on the light-emitting surface of wall lamp.
Referring to Fig. 2, further, when the distance between the light source 3 and the second reflective surface 6 are 20-40mm, described first is anti-
Smooth surface 5 reflects the light of 0 ° of -80 ° of range of light source, light of second reflective surface 6 to 80 ° -100 ° of light source of range
It is reflected, the third reflective surface 7 reflects the light of 100 ° -180 ° of light source of range.
Light source 3 is mounted on to the distance of 6 top 20-40mm of the second reflective surface, in the present embodiment, light source 3 and second is instead
The distance of smooth surface 6 is 30mm.
Referring to Figures 1 and 2, further, light of first reflective surface 5 for that will expose to the first reflective surface 5 is uniform
Ground reflexes to metope 1.
First reflective surface 5 reflects the light of 0 ° of -80 ° of range of light source, and light is reflected by the first reflective surface 5
It retrodeviates to 1 side of metope, and the metope bottom of required illumination is uniformly washed to top bright.
Referring to Fig. 4, further, curved path the first formula of satisfaction of the cross section of first reflective surface 5, described first
Formula are as follows:
Y1=0.001x3-0.033x2-0.820x+16.55
Wherein Y1 represents ordinate, and the value range of abscissa is 0≤x < 21.
The curved path of the cross section of first reflective surface 5 meets the first formula, and related coefficient reaches 0.999.
Referring to Figures 1 and 2, further, light of second reflective surface 6 for that will expose to the second reflective surface 6 is uniform
Ground reflexes to the bottom position of metope 1, and the bottom position is the wall locations close to reflector 2.
Second reflective surface 6 reflects the light of 80 ° -100 ° of light source of range, and reflection light is made to be biased to metope 1
And the bottom position of metope 1 is exposed to, the brightness of 1 bottom of metope is increased, the bottom position is the metope close to reflector 2
Position, when the bottom that wall lamp is mounted on building is irradiated upwards, construction bottom is bottom position；Otherwise, when wall lamp is installed
When being aimed downwardly at the top of building, building top is bottom position.
Referring to Fig. 5, further, curved path the second formula of satisfaction of the cross section of second reflective surface 6, described second
Formula are as follows:
Y2=-0.009x3+0.740x2-18.24x+147.1
Wherein Y2 represents ordinate, and the value range of abscissa is 21≤x < 27.
The curved path of the cross section of second reflective surface 6 meets the second formula, and related coefficient reaches 0.999.
Referring to Figures 1 and 2, further, the third reflective surface 7 is used to expose to the light reflection of third reflective surface 7
To the top position of metope 1, the top position is the wall locations far from reflector 2.
The third reflective surface 7 reflects the light of 100 ° -180 ° of light source of range, and light passes through third reflective surface
After 7, the angle for being biased to metope 1 is smaller, so exposing to the top position of metope 1.Since wall lamp is specific in use, light source 3
It is mounted on light source board, therefore part hair reflection light can be used for supplementing the dark space generated because light source board blocks and metope top
The brightness in portion；The light overflowed outward is controlled in lamps and lanterns outer simultaneously, prevents the generation of dazzle.
Referring to Fig. 6, further, the curved path of the cross section of the third reflective surface 7 meets third formula, the third
Formula are as follows:
Y3=0.031x2-1.434x+17.55
Wherein Y3 represents ordinate, and the value range of abscissa is 27≤x < 46.
The curved path of the cross section of the third reflective surface 7 meets third formula, and related coefficient reaches 0.999.
In conclusion the reflector of the present embodiment at least has the following beneficial effects:
(1), asymmetrical sectional design is carried out to reflector, then after exposing to reflector using the light of light source, led to
Cross reflector and secondary distribution carried out to light so that light equably covering wall, avoid carrying out using lens light distribution cause it is dizzy
The problem of light improves illumination comfort level and illuminating effect.
(2), it is supplemented using the reflected light of third reflective surface bright at the top of the dark space generated because light source board blocks and metope
Degree, reaches and uniformly washes wall effect, improve illuminating effect.
