Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
A kind of light high density line reflection LED lamp, which is characterized in that including taper reflector, the taper is anti-
The tool of cover is penetrated there are one the incidence hole being arranged at top, and the inner face linear circular cone reflecting surface 3 coaxial with light hole center point,
Circular cone reflecting surface extends to opening along incidence hole；LED illumination ontology includes the mounting assembly 1 to connect with incidence hole and lamp cap 2,
The incidence hole for the incident ray that lamp cap 2 generates for entirely falling in linear circular cone reflecting surface 3, in the lamp cap 2
Heart point is overlapped with the central point of incidence hole, and the central axis of lamp cap 2 is overlapped with the central axis of linear circular cone reflecting surface 3；When

Preferably, the diameter of the lamp cap 2 is less than the diameter of incidence hole, and lamp cap 2 is adapted with incidence hole, and lamp cap 2 produces
Raw light beam is all fallen in linear circular cone reflecting surface 3.
Preferably, the lamp cap 2 is mounted in mounting assembly 1, the phase of mounting assembly 1 and incidence hole on taper reflector
It connects.
Preferably, the linear circular cone reflecting surface 3 has linear gradient, and defines sloping reflector and incidence hole institute
At the inclination angle that face is formed.
Preferably, the lamp cap 2 generates light beam on linear circular cone reflecting surface 3 after multipath reflection is reinforced, anti-
The narrow angle injection light being aggregated less than beam incident angle is penetrated at cover opening, is projected from the exit of taper reflector.
As shown in Figures 2 and 3, conventional light source can be radiated the area of space more than 270 °, and LED light source can also be radiated
180 ° of area of space, but most of is all the waste being not necessarily to.As shown in Figures 4 and 5, however compared with the light source incidence of extensive angle
Light is in linearity circular conical surface, after have passed through multipath reflection, is assembled to the injection light of relative narrow-angle in outgoing plane so that penetrate
The luminous intensity of light extraction increases, while brightness is also enhanced, and when by equally distance reaches illuminated plane, brightness is penetrated higher than original
The light gone out.
When LED light source light emitting angle is 120 °, luminous intensity
I0=F/ Ω=F/ (4 π * (120 °/360 °))=3F/4 π, wherein Ω are solid angle, and F is luminous flux
After circular cone drift angle is the linearity circular conical surface set of a, I0(da)=F/ (4 π * (da/360 °))
As 120 ° of a <, I0(da) > 3F/4 π
According to the aerial attenuation law of light：After light beam passes through air x distance, luminous intensity is from I0Fall to I
(x), expression formula is:
I (x)=I0e-ax
WhereinIt is called absorption coefficient, ω is the frequency of light in formula, and c is the light velocity.
It can be seen that when light emitting angle is 120 ° of LED light intensity I0, 120 ° of linearity circular cone is less than by circular cone drift angle

h0=rkocota
Wherein rkoIndicate that 3 light extraction radius surface of linear circular cone reflecting surface, a indicate 3 vertex of a cone of linear circular cone reflecting surface half
Angle.
In order to clearly analyze multiple reflections process of the light in linear circular cone reflecting surface 3, aperture is unfolded, and builds
Coordinate system shown in Liru Fig. 6 a.Coordinate origin takes in the center of circle of 3 light-emitting surface of linear circular cone reflecting surface, and+z-axis is downward.
From Fig. 6 b as can be seen, being reflected for ith (i.e. after (2i-1) secondary reflection of linear circular cone reflecting surface 3)
Light for, from ith pip piTo the injection distance x of optical axis (i.e. z-axis)iIt is represented by
In expanded view 3, from ith pip PiTo the vertical range z of x-axisiIt is represented by
The light is represented by illumination plane position at a distance from outgoing beam center
F is linear circular cone reflecting surface 3 to the distance for needing illumination plane in formula
Formula (4) and (5) are substituted into formula (6), can be obtained
It is possible thereby to find：When the size and light source that 3 vertex of a cone half-angle of linear circular cone reflecting surface is determined to required illumination
After the distance of plane, we can produce to control freely in illumination plane via the height for changing linear circular cone reflecting surface 3
The magnitude range of raw illumination region.
As shown in FIG. 7 and 8, light high density line reflection principle LED lamp and other LED lamp brightness and energy consumption pair
Than as can be seen from Figure 8：
1, using electricity identical, the brightness of light high density line reflection principle lamps and lanterns is common LED lamp
Steep brightness 5 times or more, that is to say, that other lamps and lanterns will at least consume 5 times or more of electricity, can be only achieved same brightness.
Although 2, LED bulb is larger in the light radiation range of area of space, the brightness of fringe region without
Method meets normal illumination needs, and the projection scope of light high density line reflection principle lamps and lanterns has reached well enough
Even illuminating effect, it is not necessary that cause the waste of the energy.
As shown in Figures 9 and 10, the utility model need to only consume the electricity of 72W for 36 square metres of offices of 4 meters of floor height
Amount, it will be able to reach the average brightness of desk tops 154LUX, ground average brightness also reaches 141LUX, and practical efficiency value only has
2W/㎡.The illuminating effect in entire room is quite uniform, minimum brightness/average brightness=0.53.It is new that this demonstrates this practicality again
The advantageous effect of type.
The beneficial effects of the utility model are：
1. the radiation propagation mode of the previous light of improvement in an atmosphere, reduces light radiation and propagates the wave in area of space
Take, reduces the brightness decay generated by distance.
2. improving the brightness irregularities situation of radiation areas.
