Abstract

A luminous lamp having an ultraviolet filtering and explosion-proof thin film is disclosed. An outside of a lamp is coated by a transparent layer which comprises phosphor powder. Energy generated by the lamp is absorbed by the phosphor powder while the lamp is shining. The phosphor powder would release energy to shot brilliance, so as to provide auxiliary lighting after turning off the lamp. Additionally, the phosphor powder can absorb harmful ultraviolet and other harmful radiations with shorter wavelengths to be one part of the thin film for filtering harmful radiations. The harmful ultraviolet can be transformed by the phosphor powder into visible light to red shift radiations with short wavelengths; hence the harmful radiations with shorter wavelengths can be eliminated. The illumination of visible light can be further increased. The transparent layer can catch broken fragments of the outside of the lamp to decrease accidents when the lamp is broken.

Claims

1. A luminous lamp apparatus having an ultraviolet filtering and explosion-proof thin film, comprising:

a lamp; and

a transparent layer being made of a polymer material, applied to an outer surface of said lamp continuously contacting said lamp, said transparent layer containing a phosphor powder,

whereby an outer layer of each phosphor powder particle is coated with a ceramic material.

2. The luminous lamp apparatus of claim 1, wherein said phosphor powder is selected from the group of afterglow phosphor and photoluminescence material.

3. A luminous lamp apparatus having an ultraviolet filtering and explosion-proof thin film, comprising:

a lamp providing a first illumination means;

a phosphor layer, coated on an outside of said lamp, continuously contacting said lamp; and

a transparent layer being made of a polymer material, coated an outside of said phosphor layer, continuously contacting said phosphor layer.

4. The luminous lamp apparatus of claim 3, wherein said phosphor layer is selected from one of afterglow phosphor and photoluminescence material.

5. The luminous lamp apparatus of claim 3, further including said transparent layers to be coated between said lamp and said phosphor layer.

6. The luminous lamp apparatus of claim 3, wherein said phosphor layer comprises phosphor powders, and each powder particle of said phosphor powders being coated with a ceramic material.

7. A luminous lamp apparatus having an ultraviolet filtering and explosion-proof thin film, comprising:

a lamp;

a transparent layer made of a polymer material, coated an outside of said lamp, continuously contacting said lamp; and

wherein said transparent layer containing phosphor powders;

whereby said transparent layer catches broken fragments of said lamp when said lamp is broken.

8. A luminous lamp apparatus having an ultraviolet filtering and explosion-proof thin film comprising:

a lamp,

a shell applied to an outer surface of said lamp and containing phosphor powder, said shells continuously contacting said lamp,

an outer surface of each phosphor powder particle is coated with a ceramic material.

9. A luminous lamp apparatus having an ultraviolet filtering and explosion-proof thin film, comprising:

a fluorescent lamp; and

a transparent layer containing a non-organic phosphor powder, said phosphor powder absorbing the invisible light to convert to visible light, wherein said transparent layer coated an outside of said fluorescent lamp.
