Embodiment Construction

[0017] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0018] Such as figure 1 As shown, the light bulb of the present invention includes a glass bulb 1 and a film layer 2 . The film layer 2 is evenly applied to the bulb 1 . In one embodiment, the film layer is made of silicone rubber. Of course, in other embodiments, other materials can also be selected, as long as the material has good light transmittance and diffuse scattering to make the light emitted by the film layer softer and more uniform, and the material should also be compatible with the light bulb. The material adheres well so that glass shards do not fly when the bulb shatters.

[0019] In addition, white or colored filling substances can be added to the film layer material to make the bulb have various color effects.

[0020] figure 2 A further embodiment of the invention is shown, in which the film layer 4 is applied to the bulb 3 of the g...

Abstract

The invention provides a light bulb. The light bulb comprises an even thin film layer coated on the surface of the shell of the light bulb. The thin film layer has light transmission performance and toughness, and can be adhered to the shell material. The light bulb will not cause the glass flying, thereby increasing use safety of the light bulb.

Description

technical field [0001] The invention relates to light bulb products, in particular to a light bulb with a surface coated with silicon rubber and a manufacturing method thereof. Background technique [0002] Traditional light bulb bulbs are made of glass. Once the glass bulb is broken, the splash of broken glass will cause unsafe factors. Contents of the invention [0003] It is an object of the invention to improve the safety of the bulb of a light bulb. [0004] Another object of the present invention is to improve lighting effects. [0005] Based on the above purpose, the present invention provides a light bulb. The bulb comprises a bulb shell and a uniform film layer coated on the surface of the bulb shell. The film layer has light transmission, toughness, and can be adhered to the bulb material. [0006] In one embodiment, the membrane layer is composed of silicone rubber. [0007] In addition, white or colored fillers can be included in the film layer to make th...
