The present invention relates to a reflective lampshade that is environment-friendly and energy-saving.
The lampshade is used to converge the light transmitted from the light source so that the utilization rate of the light source can be raised, and it can be energy-saving. At present, the shape of lampshade is cylinder or cone frustum. On the process of light converging, the heat produced by the light source is concentrated on the inside of the lampshade and make the temperature of the light source raised so that the stabilization of the command system of electric circuit and the working life of the light source and the lampshade are influenced.
The object of the present invention is to offer a reflective lampshade that is environment-friendly and energy-saving to make the technical problem mentioned above solved. It includes the main body of the lampshade in which a cavity is formed, wherein said cavity diffuse axially from the end that is close to the light source to the end that is far from the light source. The inside surface of the cavity is reflective and smeared with nano coat.
As one of the preferred embodiments of the present invention, the said cavity is divided into a number of reflecting regions which are like the scarfskin of pineapple.
As one of the preferred embodiments of the present invention, the thickness of the said nano coat is 0.08-0.25 mm.
As one of the preferred embodiments of the present invention, a mounting hole is located in the upper end of the said main body of the lampshade. The said mounting hole is in the center of the main body axially.
As one of the preferred embodiments of the present invention, the shape of the said cavity is cone frustum.
As one of the preferred embodiments of the present invention, the shape of the said cavity is trumpet.
The beneficial effects from the technical scheme are:
(1) The nano coat on the inside surface of the cavity has high reflectivity for visible light and infrared light, and reflect the light and heat produced by the light source to the outside of the lampshade. In addition, the nano coat can prolong the working life of the lampshade by preventing the accumulation of dust and vapors.
(2) The shape of the cavity of the lampshade is made to diffuse axially from the end that is close to the light source to the end that is far from the light source according to the principle of optical reflection, such as trumpet or cone frustum, and it can improve the reflection effect and enhance the efficacy of the lamp by more than 30%-35%.
(3) The cavity divided into a number of reflecting regions which are like the scarfskin of pineapple optimizes the reflection effect and enhance the lighting effect of the whole lamp by more than 70%-80%.
(4) the 360° irradiation of the vertical lamp source decreases the light lost by 30% and energy cost by 70%-80% to achieve the indicator of environment-friendly.
With the following description of the drawings and specific embodiments, the invention shall be further described in details.
In
The invention has been described with reference to the preferred embodiments mentioned above; therefore it cannot limit the reference implementation of the invention. It is obvious to a person skilled in the art that structural modification and changes can be carried out without leaving the scope of the claims hereinafter and the description above.
