Abstract

The utility model discloses a transparent broadening lampshade for a lamp. The inner surface of the transparent broadening lampshade is made up by regularly arranged concave lens which are equal in size; the transparent broadening lampshade is an arc lampshade with a radian of 3-20 degrees; and the convex lens are regular polygonal. The arc lampshade with a radian of 3-20 degrees has good light collecting function, thus reducing the loss of the light source; the regular polygonal convex lens enlarge the radiation area of the light source permeating the lampshade and the luminance brightness is better under the light source with the same power. The transparent broadening lampshade enables the lamp to save more than 65% of the energy and a 18 W lighting tube of the lamp equipped with such lampshade can reach the luminance brightness of a 90W lighting tube of a common lamp with. The transparent broadening lampshade is reasonable in design, convenient to make and low in cost.

Description

A kind of transparent amplification lampshade of light fixture

Technical field

The utility model relates to lighting, is specifically related to a kind of transparent amplification lampshade of light fixture.

Background technology

Light fixture is a lighting apparatus.Light fixture generally comprises the light fixture frame, and the light fixture frame is provided with lamp tube socket, and lamp tube socket is connected with fluorescent tube, for attractive in appearance and protection fluorescent tube, also is provided with Transparent lamp shade on the light fixture frame of present most of daylight light fixture, energy-saving lamp.Along with people's the environmental protection and the raising of awareness of saving energy, more and more higher to the requirement of light fixture, wish to obtain higher illuminating effect with the fluorescent tube of less power.The energy-saving design thinking of light fixture was the applicating energy-saving fluorescent tube in the past, the energy-saving design thinking of light fixture develops into the transparent amplification lampshade of light fixture at present, as notification number is CN1109839, Granted publication day is on May 28th, 2003, name is called the patent of invention of light-amplifying transparent lampshade, the surface that discloses the regular arrangement of inner surface that faces toward light source is the light-amplifying transparent lampshade of convex convex lens, outer surface is the plane or is with the radian cambered surface slightly, inner surface is divided into three zones, zone line convex lens radius is 15～45mm, areas at both sides convex lens radius is 20～50mm, reaches preferable illuminating effect and soft illuminating ray.But necessity that this patent of invention lighting energy saving effect remains further raising.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of have gather light source better, the light irradiated area is big, with the transparent amplification lampshade of the higher a kind of light fixture of brightness under the constant power light source, its fractional energy savings can reach 65%.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of transparent amplification lampshade of light fixture, the inner surface of this transparent amplification lampshade is made up of regularly arranged equal-sized convex lens, this transparent amplification lampshade is the arc lampshade of tool 3～20 degree radians, and described convex lens are regular polygon.

This transparent amplification lampshade is the arc lampshade of tool 5～15 kilsyth basalt face radians; The arc lampshade collection light source effect of this radian is better, and outward appearance is more attractive in appearance, and is compact with the light fixture overall co-ordination.

Described convex lens are regular hexagon, also can be octagon, dodecagon, square, regular pentagon etc., and they are handsome in appearance, can fully enlarge irradiated area again.

The circumscribed concentrically ringed diameter of described convex lens is 5～100mm; In this scope, select irradiated area better and the circumscribed concentrically ringed diameter of the preferable convex lens of brightness according to the specification of lampshade.

The circumscribed concentrically ringed diameter of described convex lens is 5～14mm, and the light fixture that this scope is less or moderate to specification, rectangle lampshade and light source power are bigger is more suitable.

The circumscribed concentrically ringed diameter of described convex lens is 50～80mm, and the light fixture that lampshade such as this scope is big to specification, square or circle and light source power are bigger is more suitable.

At the inner surface of this transparent amplification lampshade, described convex lens are for vertically regularly arranged.

At the inner surface of this transparent amplification lampshade, described convex lens are for laterally regularly arranged.

Compared with prior art, advantage of the present utility model is that the inner surface of this transparent amplification lampshade is made up of regularly arranged equal-sized convex lens, and this transparent amplification lampshade is the arc lampshade of tool 3～20 degree radians, and convex lens are regular polygon; The arc lampshade of tool 3～20 degree radians has the effect of gathering light source preferably like this, reduced the waste of light source, the convex lens of regular polygon can make through the irradiated area of the light source of lampshade bigger, and it is also higher with brightness under the constant power light source, use transparent amplification lampshade of the present utility model the energy-saving effect of light fixture is reached more than 65%, can reach fluorescent tube lighting level with the 90W of the light fixture of common lampshade with the fluorescent tube of the 18W of light fixture of the present utility model.The utility model also has reasonable in design, and is easy to process, the advantage that production cost is lower.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment

The transparent amplification lampshade of a kind of light fixture as shown in Figure 1 and Figure 2, this transparent amplification lampshade 1 is rectangle, the inner surface 2 of this transparent amplification lampshade 1 is made up of to regularly arranged equal-sized orthohexagonal convex lens 3 many horizontal rows, this transparent amplification lampshade 1 is the arc lampshade of tool 8～15 degree radians, and the circumscribed concentrically ringed diameter of orthohexagonal convex lens 3 is 5～14mm.

This transparent amplification lampshade also can be square or circle etc. in the foregoing description; The inner surface of this transparent amplification lampshade also can be made up of the convex lens 3 of the vertically regularly arranged equal-sized octagon of many rows, dodecagon, pentagon etc.; The radian of this transparent amplification lampshade also can be 3～5 degree, 5～8 degree, 10～12 degree, 13～15 degree, 16～18 degree or 18～20 degree etc.; The circumscribed concentrically ringed diameter of convex lens can not enumerated at this one by one for 8～10mm, 16～25mm, 30～40mm, 60～70mm or 80～90mm etc. yet.
