Technical field
The utility model belongs to light fixture mask technical field, and in particular to a kind of Transflective combined type LED lamp optics
Mask.
Background technology
With forth generation light source, light emitting diode (Light Emitting Diode, LED) luminous efficiency and power are carried
Height, LED is being applied to increasing field.But as spot light, LED, which must carry out secondary optical design, can just be adapted to
The specific requirement of various illuminators.Currently, great power LED turns into the main product in market.Secondary optical design field
In generally there are lens and reflector two schemes, because reflector can not effectively distribute the luminous flux of LED center, lens into
For the main flow of LED lamp secondary optical design.But, great power LED is not only with very high luminous flux and luminous efficiency, and it is sent out
Light is usually polychromatic light, use lens be bound to cause polychromatic light light splitting for monochromatic light (such as rainbow).This is not only substantially reduced
The quality of light fixture, and in some fields, such as：Traffic lights field, light fixture can show the color different from design
(such as red light is rendered as yellow in some angles, and green light is also rendered as yellow in some angles), causes actual application problem.Such as
What carries out secondary optical design to the great power LED that spot light is encapsulated, and the reasonable distribution of luminous flux has both been completed, while avoiding light
Dispersion turns into a urgent problem to be solved.
The content of the invention
The purpose of this utility model is that there is provided can realize the reasonable of luminous flux in view of the foregoing defects the prior art has
Control, while avoiding the LED lamp of the Transflective combined type LED lamp optical mask of the dispersion of light.
The technical solution of the utility model is as follows：
Transflective combined type LED lamp optical mask, including two or more reflectors and a lens, its feature exist
In：The diameter of the inner surface bottom surface of second reflector is consistent with the diameter of the first reflector bottom surface, by that analogy, the 3rd reflector
Inner surface basal diameter it is consistent with the basal diameter of the second reflector；
The transparent cup that the reflector is made up of a reflective surface and a transmission plane, reflective surface is the ball of evagination
Face, transmission plane is the sphere of indent, and reflective surface is linear contact lay with transmission plane, and the line is rounded, transmission plane and bottom in reflector
Face is linear contact lay, and the line is rounded, and the inner surface bottom surface of the first reflector is provided with lens, the maximum gauge of the lens with
The diameter of reflector inner surface bottom surface is consistent.
Transflective combined type LED lamp optical mask, the reflector is the transparent cup of annular, inner surface bottom surface and
Outer surface bottom surface is circle.
Transflective combined type LED lamp optical mask, the lens are relative to reflector inner surface bottom surface evagination.
Transflective combined type LED lamp optical mask, the outer surface bottom surface of last reflector is optical mask
Preceding surface.
Transflective combined type LED lamp optical mask, the reflector is manufactured by optical glass, PC or PMMA.
The beneficial effects of the utility model are：
By the mutual cooperation of lens and reflector, luminous flux reasonable distribution is realized, different lamps optical requirement is being met
While, luminous flux of light source utilization rate is improved as far as possible, the energy is saved, while avoiding the dispersion of light significantly, and significantly improves LED
Lamp lighting quality.

Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further detail to the utility model.
As shown in figure 1, Transflective combined type LED lamp optical mask of the present utility model includes two or more annulus
Shape reflector and a lens 3.The annular that the reflector is made up of a reflective surface 1 and a transmission plane 2 is transparent
Cup.Reflective surface 1 is the sphere of evagination, and transmission plane 2 is the sphere of indent, and reflective surface 1 is linear contact lay with transmission plane 2, and the line is in
It is circular.Transmission plane 2 is linear contact lay with reflector inner bottom surface, and the line is rounded.Cup inner surface bottom surface and outer surface bottom surface are equal
For circle.
The inner surface bottom surface of first reflector is provided with lens 3, maximum gauge and the reflector inner surface bottom of the lens 3
The diameter in face is consistent, and the lens are relative to reflector inner surface bottom surface evagination.
The shape of second reflector and more reflectors, function are close with the first reflector, and simply size is different, and second is anti-
The diameter of the inner surface bottom surface of light cup is consistent with the diameter of the first reflector bottom surface, by that analogy, the inner surface of the 3rd reflector
Basal diameter is consistent with the basal diameter of the second reflector.
The outer surface bottom surface of last reflector is the preceding surface of optical mask.
The reflector is manufactured by optical glass, PC or PMMA, and the light launched by lambert's body emitting led 5 is passed through
Cross after the transmission of transmission plane 2, then reflected by reflecting surface 1, finally go out to be shot out from the preceding surface of optical mask；Close to central ray warp
Cross lens 3 and shine mask exterior by the preceding surface of optical mask.
Cooperated by the multiple reflectings surface 1 and transmission plane 2 and lens 3 of optical mask, the utility model is realized big
Power LED spot light luminous flux reasonable distribution, finally realizes that luminous flux meets the requirement of light fixture light flux distribution, while avoiding significantly
The dispersion of light, improves the quality of light fixture.
