Abstract
The utility model belongs to the technical field of application of electrodeless lamps, particularly relates to an annular electrodeless lamp light distribution structure. The annular electrodeless lamp light distribution structure comprises an annular electrodeless lamp tube, an outer reflecting cover and an inner reflecting cone. The annular electrodeless lamp light distribution structure is characterized in that the upper portion face of the outer reflecting cover is formed by a circular arc by rotating around a center, wherein the radius of the curvature of the circular arc is 159.3, the lower portion face of the outer reflecting cover is a circular ring face which is formed by three line segments by rotating around a center, inclined angles of the three line segments from bottom to top are 168 degrees, 166 degrees and 125 degrees in sequence, and the inner reflecting cone is formed by an arc line by rotating around a center, wherein the radius of the curvature of the arc line is 347. The annular electrodeless lamp light distribution structure has the advantages of solving the problems that light outside the annular electrodeless lamp tube is over divergent while light inside the annular electrodeless lamp tube is over concentrated, enabling illumination on an irradiation face by a whole lamp to be even, and improving using effect of electrodeless lamps.
Description
(1) technical field
The utility model belongs to the Non-polarized lamp applied technical field, particularly a kind of annular electrodeless lamp light distribution structure.
(2) background technology
Non-polarized lamp is the abbreviation of Promise Light high-frequency plasma discharge Non-polarized lamp, being the new high-tech product that the up-to-date scientific and technological achievements in field such as integrated application optics, power electronics, plasma, magnetic material are developed out, is a kind of new type light source that represents the high light efficiency of lighting engineering, long-life, the development of high-color rendering future directions.Yet, what most of Non-polarized lamp reflectors adopted in the market is the parabolic shape reflector that traditional bulb lamp adopts, this reflector has good luminous intensity distribution effect to the bulb lamp of spot light form, but the annular electrode-less fluorescent tube light distribution effect of opposite form of light source is very undesirable, cause Non-polarized lamp even at the uneven illumination of shadow surface, affect the result of use of product, reduced the advantage of Non-polarized lamp.
(3) summary of the invention
The utility model provides a kind of efficient high, practical and convenient annular electrodeless lamp light distribution structure in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of annular electrodeless lamp light distribution structure, comprise annular electrode-less fluorescent tube, external reflectance cover and internal reflection cone, it is characterized in that: it is that 159.3 circular arc forms around central rotation that described external reflectance cover upper side adopts radius of curvature, the anchor ring of bottom surfaces for being formed around central rotation by three line segments, the inclination angle of three line segments from top to bottom is followed successively by 168 °, 166 ° and 125 °, and it is that 347 camber line forms around central rotation that internal reflection cone adopts radius of curvature.
The beneficial effects of the utility model are: the external reflectance cover of this structure and internal reflection cone cooperatively interact, having solved annular electrode-less fluorescent tube outer beam too disperses and the too concentrated problem of inboard light, make the illumination of whole light fixture on shadow surface more even, improved the result of use of Non-polarized lamp, can be widely used in Non-polarized lamp bulkhead lamp capable application, have great application value.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is distribution curve flux figure of the present utility model;
Among the figure, 1 annular electrode-less fluorescent tube, 2 external reflectance covers, 3 internal reflections cone.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises annular electrode-less fluorescent tube 1, external reflectance cover 2 and internal reflection cone 3, it is that 159.3 circular arc forms around central rotation that external reflectance cover 2 upper side adopt radius of curvature, the anchor ring of bottom surfaces for being formed around central rotation by three line segments, the inclination angle of three line segments from top to bottom is followed successively by 168 °, 166 ° and 125 °, and it is that 347 camber line forms around central rotation that internal reflection cone 3 adopts radius of curvature.
Adopt a kind of annular electrodeless lamp light distribution structure of the present utility model, radius of curvature is adopted on external reflectance cover 2 tops, and to be 159.3 circular arc become face to be used for the light of reflective annular electrodeless lamp tube 1 upper outside emission around central rotation; External reflectance cover 2 bottoms adopt anchor ring that three line segments that from top to bottom inclination angle is followed successively by 168 °, 166 ° and 125 ° form around central rotation as reflecting surface, be used for the light that annular electrode-less fluorescent tube 1 lower outside sends is reflected, simultaneously to carrying out secondary reflection by internal reflection cone 3 light that reflect; External reflectance cover integral body has the effect of concentrating light and bringing the light of too dispersing together of dispersing.It is that 347 camber line is around the central rotation moulding that internal reflection cone 3 adopts radius of curvature, its effect is similar to convex reflecting mirror, the light in light fixture centre focus that annular electrodeless lamp pipe 1 inboard is sent reflects away in the mode of dispersing, and makes whole light fixture more even in the illumination of shadow surface when reducing the Non-polarized lamp center brightness.External reflectance cover and internal reflection cone cooperatively interact, having solved annular electrode-less fluorescent tube outer beam too disperses and the too concentrated problem of inboard light, make the illumination of whole light fixture on shadow surface more even, improved the result of use of Non-polarized lamp, can be widely used in Non-polarized lamp bulkhead lamp capable application, have great application value.
