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
The present invention relates to a kind of glass bulb of LED lamp, the particularly application of a kind of epoxy resin on LED lamp glass lamp shade.
Background technology
In prior art, LED lamp adopts glass lamp shade (bulb part) usually, this glass lamp shade a period of time after light fixture is lighted, or do not light and just appear in transparent glass component inside and form solidifying mist or solidifying water phenomenon, have a strong impact on the aesthetic property of light fixture, light transmission, also has a strong impact on the service life of light fixture.And the reason of described solidifying mist and solidifying water is: LED lamp inside (mainly glass component inner space) can not accomplish complete sealed vacuum state, so be full of air in lamp interior, generally all containing water vapor in air, and lamp interior air belongs to dead state, can not circulate easily, just there will be following several solidifying mist, solidifying aqueous condition when variation of ambient temperature is large:
The first: environment temperature by high step-down, the metal parts of light fixture in change procedure, the temperature of the air of glass component and lamp interior is also in a process by high step-down, according to the ratio thermal analyses of 3 kinds of materials, what temperature reduction was the fastest is air, then glass component, last metal parts.Because cold air touches the glass slightly higher than his temperature there will not be condensation.So there will not be solidifying mist phenomenon in such variation of temperature where, but finally can there is metal part surface in the mode of tiny drops of water in the steam in whole change procedure in air.
The second: environment temperature is uprised by low, the metal parts of light fixture in change procedure, the temperature of the air of glass component and lamp interior is also in one by the low process uprised, equally according to the ratio thermal analyses of 3 kinds of materials, what temperature rising was the fastest is air, then be glass component, last metal parts.After air themperature raises, glass component and metal parts are also in low-temperature condition, and the steam so in air will run into cryogenic object and occur condensation, so just there is solidifying mist phenomenon on glass component in this case.
The third: after light fixture is lighted, a certain amount of moisture can be formed in lamp interior by after two kinds of variation of ambient temperature above, after light fixture is lighted, because the metal parts of light fixture is used to dispel the heat to LED, so metal parts temperature raises very soon, moisture above metal is become steam by evaporation at once, runs into the ice-cold glass not having enough time to heat up and is just condensed into the solidifying mist phenomenon of tiny drops of water appearance at once, and the last globule constantly accumulates finally directly sees solidifying water on glass component.
Summary of the invention
The object of the invention is to provide according to the deficiencies in the prior art part one can effectively prevent glass lamp shade from coagulating water, solidifying mist, guarantee the application of the epoxy resin in light fixture translucent effect and service life on LED lamp glass lamp shade.
The object of the invention is to be realized by following approach:
The application of epoxy resin on LED lamp glass lamp shade, LED lamp includes glass cell-shell, and its main points are, the medial surface of glass cell-shell is coated with layer of transparent epoxy resin, forms thin film and be close to inside glass cell-shell after this epoxy resin cure.
Epoxy resin is the organic compound containing two or more epoxide groups in general reference molecule, epoxy resin after solidification has good physics, chemical property, it has excellent adhesive strength to the surface of metal and nonmetallic materials, dielectric properties are good, set shrinkage factor is little, product size good stability, hardness is high, pliability is better, thus national defence, each department of national economy is widely used in, pour into a mould, flood, the purposes such as lamination material, bonding agent, coating, in addition can also as modifier.These application are all various physics based on epoxy resin or chemical characteristic.In coating, because the weatherability of epoxy coating is poor, paint film out of doors easily efflorescence loss of gloss owe again plentiful, should not be used as outdoor coating and high-decoration coating, therefore epoxy coating is mainly used as anti-corrosive paint, metal primer, insulated paint.
The present invention by spraying transparent epoxy resin inside glass cell-shell, thus increases the epoxy resin thin film of layer of transparent on glass cell-shell medial surface, and like this, what contact with air in glass cell-shell inside is exactly the epoxy resin thin film sprayed.First, transparent epoxy resin thin film does not affect the radiation response of light fixture; Secondly, due to the non-conductor that epoxy resin thin film is heat, specific heat is little, therefore its surface temperature can keep identical with the air themperature of lamp interior fast, substantially there will not be temperature difference, so be not easy solidifying mist in the situation lower-glass lampshade not having the temperature difference or the very little temperature difference, epoxy resin has hydrophily in addition, and it effectively can prevent the condensation of steam.Thus, LED lamp antifog spray coating glass lamp shade of the present invention effectively can prevent solidifying water in glass lamp shade, solidifying mist, thus guarantees the translucent effect of light fixture, keeps its aesthetic and decorative effect, and can ensure the service life of light fixture.
Detailed description of the invention
Most preferred embodiment:
The application of epoxy resin on LED lamp glass lamp shade, specific as follows:
Described LED lamp has transparent glass cell-shell, lamp pearl post by this glass envelope clamshell, and is connected with the lamp socket (radiator) of LED lamp;
The epoxy resin that even application last layer is transparent on the medial surface of glass cell-shell;
Described epoxy resin is at the medial surface gel solidification of glass cell-shell, and final formation one deck epoxy resin thin film, is close to glass cell-shell la m;
Epoxy resin thin film and glass cell-shell form transparent glass lamp shade thus.
Epoxy resin of the present invention is the Specific Heat Capacity that make use of epoxy resin in the application of glass cell-shell, it is as sandstone, specific heat is little, it is the non-conductor of heat, therefore, it is possible to change with environment temperature rapidly, keep consistent temperature almost identical with environment, like this, no matter temperature raises or reduces, and glass lamp shade all can not cause solidifying water, solidifying mist phenomenon because of the change of environment temperature.Application due to epoxy resin is that dielectric properties are good, and set shrinkage factor is little, product size good stability, and hardness is high because it has excellent adhesive strength mostly, and pliability is better, to the physical characteristic such as alkali and most of solvent-stable or chemical characteristic.At present, there is no and carry out according to the Specific Heat Capacity of epoxy resin the project applied, particularly be not applied to the technological project on the glass cell-shell of light fixture, therefore, the present invention is the application breaching traditional epoxy resin, it is applied in especially on light fixture, and achieve good technique effect: prevent the solidifying mist of glass lamp shade or solidifying water phenomenon, ensure that the aesthetic property of light fixture, light transmission, also effectively improve the service life of light fixture.
