Abstract
The utility model provides a lamp cover, which comprises a lamp cover main body whose reflecting plane is a paraboloid, and the opening of the lamp cover main body is rectangular, the reflecting plane is formed by two or more than two arcs which are respectively connected, and the curvature central lines of the arcs are parallel to an axial line of a lamp tube which is arranged in the lamp cover. The utility model utilizes the reflecting principle of the light, and changes the reflecting angle of the light, and light spots are rectangular, and the areas of the light spots are larger than light spots which are attained by using a common lamp cover, thereby realizing excellent lighting effect.
Description
Technical field
The utility model relates to a kind of lampshade, relates in particular to a kind of lampshade that is used for indoor and outdoor lighting.
Background technology
The profile major part of present various lampshades is hemispherical, semiellipse shape or round table-like, and the making material of lampshade body generally adopts metal, plastics or textile article, and the inner surface of lampshade body scribbles white paint or enamel, and it mainly acts on and is the light of light source is gathered certain direction.But because lampshade structurally designs unreasonable, and lampshade inner surface also there is no special design, makes quilt cover bulk absorption of part light or the scattering that light source sends, light can't be as required according to specific angle, make illuminating effect desirable not to the utmost, wasted electric energy.
Especially be applied to the lampshade on the street lamp, for convenience pedestrian and vehicular traffic, need light-illuminating the hot spot on ground try one's best longer, and hot spot to try one's best more even, but present lampshade can't address these problems.
Summary of the invention
The purpose of this utility model is to provide a kind of lampshade, makes under the effect of this lampshade, and hot spot is that the uniformity of rectangle and hot spot is good, can better play illuminating effect; And use this lampshade can more efficient use luminous energy, reach purpose of energy saving.
For reaching above-mentioned technical purpose, the technical solution adopted in the utility model is: this lampshade comprises a lampshade body, and the reflecting surface of lampshade body is parabolic, and the opening of lampshade body is a rectangle;
The reflecting surface of lampshade body is made of the arc that two or more connect successively, and the center-of-curvature line of described arc is parallel to the axis that is placed on the fluorescent tube in this lampshade;
The arc undulate that two or more of reflecting surface connect successively;
The reflecting surface of lampshade body is coated with reflectance coating;
Two sides of lampshade body are frosting;
Reflectance coating is a metal film;
Reflectance coating is ultraviolet film;
Reflectance coating is the cold light film.
Because the utility model comprises a lampshade body, the reflecting surface of lampshade body is parabolic, the reflecting surface of lampshade body is parabolic, the opening of lampshade body is a rectangle, so utilize the reflection of light principle, changed the reflection of light angle, make hot spot also be rectangle, and the area of this hot spot is greater than the hot spot that uses general lampshade to obtain, thereby plays good illuminating effect;
In a preferred embodiment of the present utility model, because the reflecting surface of lampshade body is made of the arc that two or more connect successively, and the center-of-curvature line of described arc is parallel to the axis that is placed on the fluorescent tube in this lampshade, utilize the reflection of light principle, changed the reflection of light angle, thus use the uniformity of the hot spot that this lampshade obtains good, and can better collect light, thereby better utilization luminous energy reaches purpose of energy saving;
In a preferred embodiment of the present utility model, because two or more arc undulates that connect successively of reflecting surface,, reach energy-conservation purpose and can be so that improve the uniformity of hot spot so can improve the utilization rate of light;
In a preferred embodiment of the present utility model,,, avoid injuring human eye so can prevent dazzle because two sides of lampshade body are frosting.

The specific embodiment
As shown in Figure 1, the utility model comprises a lampshade body 101, and the reflecting surface 102 of lampshade body 101 is parabolic, and the opening of lampshade body 101 is a rectangle;
As Fig. 2, shown in Figure 3, the reflecting surface 102 of lampshade body 101 is made of the arc that two or more connect successively, and the center-of-curvature line of described arc is parallel to the axis that is placed on the fluorescent tube in this lampshade;
As shown in Figure 4, the arc undulate that connects successively of two or more of reflecting surface 102;
Two sides of lampshade body are frosting;
The reflecting surface 102 of lampshade body 101 is coated with reflectance coating, and reflectance coating is ultraviolet film or cold light film, and the material that lampshade adopts is a glass.
