Abstract
The long afterglow fluorescent lamp shade has one base body containing long afterglow fluorescent powder or has long afterglow fluorescent powder coating in the surface. The long afterglow fluorescent powder may be activated with lamp light to absorb light energy and may have its absorbed light energy released to provide long time lighting after the lamp is put off. The present invention may be used in night navigation or leading way and is energy saving.
Description
Technical field:
The present invention relates to a kind of fluorescent lamp shade, relate in particular to a kind of long after-glow fluorescent lamp shade.
Background technology:
Long lad phosphor has three classes, the long lad phosphor of burn red (abbreviation rouge and powder)---yttrium oxysulfide europium; Long lad phosphor (being called for short yellowish green powder)---the strontium aluminate of europium activated by dysprosium of jaundice green light; Send the fluorescent material (being called for short bluish-green powder) of bluish-green coloured light---the strontium aluminate that the europium holmium activates.These long lad phosphors can send fluorescence under the exciting of ultraviolet light or visible light, when stop the irradiation exciting after, long lad phosphor still can send fluorescence, people are referred to as twilight sunset.There is half an hour the time that rouge and powder sends twilight sunset; The time that yellowish green powder sends twilight sunset has 2～6 hours, the time that blue green powder sends twilight sunset then reaches 4～10 hours, because of long lad phosphor has above-mentioned characteristic, it has been applied in plastics, pottery, glass, paint and the coating, forms various long afterglow products such as noctilucence electric switch box, Noctilucent ceramics, luminous paint, luminescent coating.But up to the present, also there is not long after-glow fluorescent lamp shade.
Summary of the invention:
Goal of the invention of the present invention provides a kind of long after-glow fluorescent lamp shade, and this fluorescent lamp shade still can send surplus light for a long time after turning off the light, and is fit to prompting navigation at night, leads the way.
A kind of long after-glow fluorescent lamp shade is characterized in that: the matrix at lampshade contains long lad phosphor.
A kind of long after-glow fluorescent lamp shade is characterized in that: be provided with the long lad phosphor coating on the lampshade surface.
Long after-glow fluorescent lamp shade is characterized in that: all apply the long lad phosphor coating on lampshade inner surface.
Long after-glow fluorescent lamp shade is characterized in that: be provided with the long lad phosphor coating on the local surfaces of lampshade.
Described long lad phosphor has monochromatic type long lad phosphor and compound long lad phosphor two big classes, and monochromatic type long lad phosphor is divided into three kinds in rouge and powder, yellowish green powder, bluish-green powder again; The colour temperature of compound long lad phosphor is 2700K～14500K, and it is formulated by rouge and powder, yellowish green powder, three kinds of monochromatic type long lad phosphors of bluish-green powder.
Owing to contain long lad phosphor or in lampshade surface-coated long lad phosphor coating at the lampshade matrix, under the activation of light, the long lad phosphor coating can absorb luminous energy, after the light-off, the long lad phosphor coating can discharge the luminous energy that absorbs lentamente, send twilight sunset for a long time, this fluorescent lamp shade is fit to prompting navigation at night, leads the way, and is a kind of energy-conserving product worthy of the name.
Description of drawings:
Fig. 1 contains the structural representation of long lad phosphor lampshade for matrix;
Fig. 2 scribbles the structural representation of long lad phosphor lampshade for inner surface;
Among the figure: the 1-lampshade; 2-long lad phosphor coating;
The specific embodiment:
Below in conjunction with description of drawings the specific embodiment of the present invention:
Embodiment 1: described long after-glow fluorescent lamp shade contains long lad phosphor at the matrix of lampshade 1, as shown in Figure 1.
Embodiment 2: described long after-glow fluorescent lamp shade is provided with long lad phosphor coating 2 at the inner surface of lampshade 1, as shown in Figure 2.
This long after-glow fluorescent lamp shade, it is to be mixed into the long lad phosphor of various colour temperatures with red, blue green, three kinds of fluorescent material of yellow green or with them, directly be coated in after the slurrying on the surface of lampshade, also long lad phosphor can be mixed in the lampshade base material, this lampshade has stronger twilight sunset.
The long after-glow fluorescent lamp shade of said structure is suitable for all lampshades, needs only in all technical schemes that contain long lad phosphor on the lampshade all within protection scope of the present invention.
Claims (4)
