Problems solved by technology

[0002] In the prior art, LED lamps usually use a glass lampshade (bulb part). This glass lampshade will form condensation fog or condensation inside the transparent glass part after a period of time after the lamp is lit, or if it is not lit, which is serious. Affect the aesthetics and light transmittance of the lamps, and seriously affect the service life of the lamps

Embodiment Construction

[0011] Best practice:

[0012] The application of epoxy resin on the glass lampshade of LED lamps is as follows:

[0013] The LED lamp has a transparent glass bulb, which covers the lamp bead column and is connected with the lamp holder (radiator) of the LED lamp;

[0014] Evenly spray a layer of transparent epoxy resin on the inner surface of the glass bulb;

[0015] The epoxy resin is gel-cured on the inner surface of the glass bulb, and finally forms a layer of epoxy resin film, which is closely attached to the inner layer of the glass bulb;

[0016] The epoxy resin film and the glass bulb thus form a transparent glass lampshade.

[0017] The application of the epoxy resin in the glass bulb of the present invention utilizes the specific heat characteristic of the epoxy resin, which is like sand and gravel, has a small specific heat, and is a poor conductor of heat, so it can rapidly change with the ambient temperature and maintain the same temperature as the environment. ...

Abstract

The invention relates to a glass bulb of an LED lamp, in particular to application of epoxy resin to an LED lamp glass lampshade. The LED lamp comprises a glass bulb shell, and is characterized in that the inner side face of the glass bulb shell is sprayed with a layer of transparent epoxy resin, and after curing, the epoxy resin forms a layer of film clinging to the inner side of the glass bulb shell. The application has the advantages that since the epoxy resin film is a poor conductor of heat and small in specific heat, the surface temperature of the film can be quickly kept identical with air temperature inside the lamp, temperature difference is avoided, and fog coagulation is less prone to happening in the glass lampshade; in addition, condensation of vapor can be effectively prevented as the epoxy resin has hydrophilicity. Thus, the LED lamp antifog coated glass lampshad can effectively prevent water condensation and fog coagulation therein so as to ensure light-transmitting effect of the lamp, maintain esthetic effect and decorative effect and guarantee service life of the lamp.

Description

technical field [0001] The invention relates to a glass bulb of an LED lamp, in particular to the application of epoxy resin on the glass lampshade of the LED lamp. Background technique [0002] In the prior art, LED lamps usually use a glass lampshade (bulb part). This glass lampshade will form condensation fog or condensation inside the transparent glass part after a period of time after the lamp is lit, or if it is not lit, which is serious. It affects the aesthetics and light transmittance of the lamps, and also seriously affects the service life of the lamps. The reason for the condensation of fog and water is that the inside of the LED lamp (mainly the inner space of the glass parts) cannot be completely sealed in a vacuum state, so the inside of the lamp is full of air. Generally, the air contains water vapor, and The air inside the lamp is in a stagnant state and cannot be easily circulated. When the ambient temperature changes greatly, the following conditions of c...
