Description
Technical field
The utility model belongs to light fixture face mask art, is specifically related to a kind of faceted pebble hemispherical Shell LED lamp optical mask.
Background technology
As forth generation illumination, light emitting diode (LightEmittingDiode, LED) comes into our life gradually.But LED is spot light, needs to carry out secondary optical design and just can be applied to various lighting.Along with the raising of LED luminous efficiency and the increase of power, great power LED is becoming the main product in market.The secondary optical design of great power LED of spot light encapsulation becomes an important problem.
The main distinction of great power LED and low-power LED is: low-power LED has often carried out primary optical design, and its light emitted has certain directive property and half light intensity angle; And great power LED generally direct encapsulation, do not carry out corresponding optical design, the Lambertian radiator of the light access expansion diffusing surface that it emits.For the change of this luminous characteristics, traditional secondary optical design method for low-power LED luminous characteristics, can not meet the requirement of great power LED.
Utility model content
The purpose of this utility model, for providing a kind of faceted pebble hemispherical Shell LED lamp optical mask, can meet great power LED requirement, and improve the utilization rate of luminous flux.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of faceted pebble hemispherical Shell LED lamp optical mask, it comprises bottom outer spherical shell, interior spherical shell, face shield; Be respectively from the center of outer spherical shell to periphery: ground floor is equally distributed some isosceles triangles around summit, and the second layer to last one deck is respectively several equally distributed isosceles trapezoids; The base of each isosceles triangle is respectively connected with the upper base of an isosceles trapezoid, and the bottom of each isosceles trapezoid except last one deck is connected with the upper base of lower one deck isosceles trapezoid respectively; The structure of interior spherical shell is identical with outer spherical shell, and the size of interior spherical shell is less than outer spherical shell; The bottom of interior spherical shell and outer spherical shell is by being connected bottom face shield; The partial interior surrounded bottom interior spherical shell, outer spherical shell, face shield is transparent optical material.
The bottom surface of described outer spherical shell is approximate annulus or approximate elliptical ring.
The circumradius in the outside bottom described face shield is 50mm, and the circumradius bottom face shield inside 5 is 40mm.
Described transparent optical material is optical glass, PC or PMMA.
The beneficial effects of the utility model are:
The spherical shell of a kind of faceted pebble hemispherical Shell LED lamp optical mask that the utility model provides by by light fixture enclosure design being faceted pebble composition, and by designing the shape and size of faceted pebble, the value realizing great power LED spot light luminous flux distributes and angular distribution, realize luminous flux and meet the requirement of light fixture light flux distribution, improve luminous flux utilization rate simultaneously, reach the object of economize energy, improve the quality of light fixture.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model and beneficial effect are described further.
As shown in Figure 1, faceted pebble hemispherical Shell LED lamp optical mask of the present utility model to comprise bottom outer spherical shell 1, interior spherical shell 2, face shield 5.
As shown in Figure 2, outer spherical shell 1 is made up of several faceted pebbles.In the present embodiment, be respectively from the center of outer spherical shell 1 to periphery: ground floor is equally distributed 18 isosceles triangles around summit, and the second layer is respectively 18 equally distributed isosceles trapezoids to the 4th layer; The base of each isosceles triangle is respectively connected with the upper base of an isosceles trapezoid, and the bottom of second, third layer of each isosceles trapezoid is connected with the upper base of lower one deck isosceles trapezoid respectively.In another embodiment, the faceted pebble forming outer spherical shell 1 surface is the pentagon on similar football surface, hexagonal combination.
The bottom surface of outer spherical shell 1 is approximate annulus.In another embodiment, the bottom surface of outer spherical shell 1 is approximate elliptical ring.
The structure of interior spherical shell 2 is identical with outer spherical shell 1, and the size of interior spherical shell 2 is less than outer spherical shell 1.The bottom of interior spherical shell 2 and outer spherical shell 1 is by 5 being connected bottom face shield.Bottom face shield, the circumradius in outside of 5 is 50mm, and the circumradius bottom face shield inside 5 is 40mm.Bottom interior spherical shell 2, outer spherical shell 1, face shield, 5 partial interiors surrounded are transparent optical material, can use optical glass, PC or PMMA.
As shown in Figure 3, lambert's body emitting led 3 be positioned at faceted pebble hemispherical Shell LED lamp optical mask face shield bottom 5 circumscribed circle circle centre position.The light that lambert's body emitting led 3 sends is each passed through the interior spherical shell 2 of faceted pebble hemispherical Shell LED lamp optical mask and outer spherical shell 1 injects to mask exterior.
By cooperatively interacting of the faceted pebble of interior spherical shell 2, outer spherical shell 1, the value that the utility model realizes great power LED spot light luminous flux distributes and angular distribution, finally realize luminous flux and meet the requirement of light fixture light flux distribution, improve luminous flux utilization rate simultaneously, reach the object of economize energy, improve the quality of light fixture.
