Abstract
The utility model relates to a lamp fitting which comprises a main body part, a light source and a transparent lampshade, wherein inner surface of the lampshade consists of a plurality of convex lenses which are regularly arranged on the inner surface of the convex lenses in the longitudinal direction or/and in the transverse direction, the radiuses of the convex lenses are R1, R2, R3 until Rn in sequence, the R1 is the radius of a central lens, the radius of the lens satisfies the following relationship: Rn=R1*Kn, K is the grading coefficient, wherein K is greater than 1.0 and less than or equal to 1.2, n is a constant, and n is greater than or equal to 3 and less than or equal to 50. The utility model also discloses a lampshade of the lamp fitting.
Description
[technical field]
The utility model relates to lighting technical field, or rather, relates to a kind of light fixture and lampshade thereof.
[background technology]
Light fixture is as one of important tool of daily life, playing the part of more and more important role in people's nowadays life.Along with the lifting of people, illuminating effect, the quality of lighting lamp of light fixture are had higher requirement to the requirement of quality of life.Present light fixture is improving illumination efficiency, is improving and also have the very big not enough and space that promotes aspect the quality of lighting.The utility model just is being based on this current demand and is proposing.
[utility model content]
The technical problem that the utility model solves is to overcome the defective that prior art exists, and a kind of illumination efficiency height, light fixture and lampshade thereof that quality of lighting is good are provided.
The utility model is achieved through the following technical solutions: a kind of light fixture, comprise main part, light source and lampshade, the inner surface of described lampshade is made up of regularly arranged some convex lens, and vertically or/and horizontal well-regulated being arranged in order, radius is followed successively by R1 to described convex lens at the inner surface of lampshade, R2, R3 ..., Rn, wherein R1 is the center lens radius, and the radius of described convex lens satisfies following relationship: Rn=R1 * K
n, wherein K is the luminous intensity distribution coefficient, 1.0＜K≤1.2; N is a constant, 3≤n≤50.
Described lampshade is plane or cambered surface along the outer surface of light source direction of illumination.
Described convex lens radius is 5mm-50mm.
Described convex lens are the bar shaped convex lens.
A kind of transparent lampshade, inner surface is made up of regularly arranged some convex lens, described convex lens are vertical or/and horizontal well-regulated being arranged in order at the inner surface of lampshade, radius is followed successively by R1, R2, R3, Rn, wherein R1 is the center lens radius, the radius of described convex lens satisfies following relationship: Rn=R1 * K
n, wherein K is the luminous intensity distribution coefficient, 1.0＜K≤1.2; N is a constant, 3≤n≤50.
Described lampshade is plane or cambered surface along the outer surface of light source direction of illumination.
Described convex lens radius is 5mm-50mm.
Described convex lens are the bar shaped convex lens.
Compared with prior art, the utility model is provided with convex lens by the inner surface at the light fixture lampshade according to the rule of setting, the light that light source is sent has carried out effective amplification, and light is soft when penetrating light fixture through the light that lampshade was nursed one's health, avoided the stimulation of light source to naked eyes, when improving illumination efficiency, significantly improved the quality of lighting of light fixture.
[description of drawings]
Fig. 1 is the solid assembling schematic diagram of the utility model light fixture.
Fig. 2 is the lampshade of the utility model light fixture carries out projection from interior side direction a schematic diagram.
Fig. 3 is the analyse and observe enlarged diagram of Fig. 2 along the A-A direction.
[specific embodiment]
See also shown in Figure 1, it is a fluorescent tube that the utility model light fixture 8 comprises in lampshade 1, main part 2 and the light source 3(present embodiment), described light source 3 is installed on the main part 2, and described lampshade 1 is assembled on the main part 2, light source 3 is enclosed in the space of lampshade 1 and main part 2 formation.
See also Fig. 2 and shown in Figure 3, described lampshade 1 is transparent, and the part facing to light source is arcuation in the present embodiment, certainly the actual demand according to light fixture also can be plane, and the inner surface of described lampshade 1 is made up of regularly arranged some convex lens, has 11 convex lens 11 ' that are bar shaped along the lampshade length direction in the present embodiment, 12 ', 13 ', 14 ', 15 ', 10,11,12,13,14,15, above-mentioned convex lens are that the center is symmetrical arranged with center convex lens 10, the rule of arranging of left and right sides two parts convex lens of symmetry is the same, for convenience of description, be that example describes only in the present embodiment with arranging of convex lens 10 to 15, the radius of convex lens 10 to 15 is followed successively by R1, R2, R3, R4, R5, R6, the radius of above-mentioned convex lens satisfies following relationship: Rn=R1 * K
n, wherein K is the luminous intensity distribution coefficient, 1.0＜K≤1.2; N is a constant, 3≤n≤50.R1 is the radius of center lens 10.The radius of described convex lens is 5mm-50mm.
Described in the present embodiment convex lens are laterally clocklike to arrange along the length direction of lampshade, can certainly vertically clocklike arrange at the inner surface of lampshade.
More than describing is embodiment of the present utility model only, forgives and can understand, and under the prerequisite that does not depart from the utility model design, all should be included within the technical conceive of the present utility model simple modification of the present utility model and replacement.
