Abstract

The utility model discloses a lamp, which comprises a light-emitting body, a base plate and a lamp shade, wherein the base plate is fixed onto the light-emitting body, and the lamp shade is arranged on the light-emitting body. A cavity arranged between the light-emitting body and the lamp shade is filled with transparent silica gel, and scattering diluents are distributed among the silica gel. Thetransparent silica gel in the cavity can not only transmit light, but also prevent water vapor or mist from forming on the inner wall of the lamp shade, further the transparent silica gel can be adopted to absorb residual moisture inside the lamp shade and prevent water steam inside the lamp shade condensing into water mist and adhering to the inner wall of the lamp shade, thereby the lamp is ensured to have long-term comparatively high light-emitting effect. Additionally, the lamp has the advantages of simple structure, convenient manufacture and maintenance and great practical and convenient property. Further, as the scattering diluents are distributed among the silica gel, fluorescent light with different colors can be simultaneously employed to adjust the color of scattered light whenthe scattering effect is improved. Accordingly, the scattering effect of the lamp is greatly improved.

Be distributed with scattering diluent in the described silica gel.

Described illuminator is at least one LED, further comprises the solar panel that is fixed on the described substrate and connects described LED, and described at least one LED is distributed in described solar cell panel area.

Further comprise the battery that connects described solar panel and LED.

The silicon gel part of corresponding described LED is distributed with scattering diluent, and the silicon gel part of corresponding described solar panel does not have scattering diluent.

Described scattering diluent is the leaded light powder.

Described leaded light powder is a fluorescence leaded light powder.

Described lampshade inwall or outer wall have at least one diffusion barrier.

Described lampshade is circular, square or oval.

Transparent silica gel in the cavity described in the utility model is light-permeable not only, also can prevent the formation of lampshade inwall steam or fog because fill described cavity, further also can be used to adsorb the residue moisture content in the lampshade, prevent that the condensation of moisture in the lampshade from becoming water smoke attached on the lampshade inwall, guarantee that light fixture has higher illumination effect for a long time; In addition, the utility model is simple in structure, is convenient to make and maintenance, has practicality and convenience.

Be distributed with fluorescence leaded light powder in the described silica gel, the color that also can adopt the fluorescence of different colours to regulate the light that scatters when improving dispersion effect has improved its dispersion effect greatly.
