Abstract
The utility model provides a nucleated glass lampshade, which is composed of a main body 1 of the nucleated glass lampshade, a light source reflecting layer 2, a light source installation port 3 and a light radiation port 4, wherein the light source reflecting layer 2 is tightly attached to the inner surface of the main body 1 of the nucleated glass lampshade; the light source installation port 3 is placed at the top of the main body 1 of the nucleated glass lampshade; the light radiation port 4 is placed at the bottom of the main body 1 of the nucleated glass lampshade; the main body 1 of the nucleated glass lampshade can be various shapes of a conic shape, a bowl shape, a semi-sphere shape, etc. The utility model has the advantages that the glass ceramic lampshade resisting high temperature and high heat is safe, and due to the adoption of the nucleated glass as the main body of the lampshade, the nucleated glass lampshade is not easily broken off under the conditions of high-speed heating up and high temperature and heat, and thus, the safety of the surrounding components is ensured; the light energy utilization ratio is high, the radiation effect is good and the filming effect of high reflectivity is utilized to largely enhance the light energy utilization ratio. The utility model can be used in lampshade equipment with high-power radiation light sources, such as a data projector, a back projection television, etc.
Description
Technical field
The utility model relates to a kind of lampshade, relates in particular to a kind of micro-crystal glass lampshade.
Background technology
Current, in electronic products such as data projector, back projection TV, often need high-power heat radiation light source, to be a hectowatt do not wait to hundreds of watts its power, and during light source luminescent, some electric energy has changed into luminous energy, and another part electric energy has changed into heat energy, and a part changes into heat energy by luminous energy, causes light source and temperature rise on every side is fast, temperature is high.Therefore, must keep apart light source and other components and parts on every side, promptly high-power heat radiation light source must place lampshade.Simultaneously, lampshade to high-power heat radiation light source has proposed high requirement, traditional glass lamp shade is owing to its coefficient of expansion height, bad mechanical strength, heat-resisting poor, very easily cracked when high temperature, not only electronic product itself is caused damage, serious also can cause the burning of combustible on every side, thereby enlarge damage range.
Summary of the invention
The utility model by following technical proposals and constructional device, proposes a kind of low-expansion coefficient, high mechanical properties, high temperature resistant high hot, safe and reliable micro-crystal glass lampshade at the deficiencies in the prior art.
A kind of micro-crystal glass lampshade is made up of micro-crystal glass lampshade body 1, light source reflecting layer 2, light source installing port 3, light radiation mouth 4, and light source reflecting layer 2 is close to the inner surface of micro-crystal glass lampshade body 1.Devitrified glass claims glass ceramics again, and it has concentrated the two-fold advantage of glass and pottery, has low-expansion coefficient, valuable performances such as high mechanical properties, chemical stability and Heat stability is good, serviceability temperature height and hard wear resistant.So the heat resisting temperature of micro-crystal glass lampshade body 1 is more than 500 degree Celsius, even up to 700 degree Celsius, can guarantee under the temperature rise of high power light source, and is safe and reliable, not easily broken.Micro-crystal glass lampshade body 1 can be different shapes such as taper shape, bowl-type, hemispherical.Light source reflecting layer 2 is the plating dura mater material of high reflectance, can improve the utilization rate of luminous energy, and light source reflecting layer 2 covers the inner surface of whole micro-crystal glass lampshade body 1.Light source installing port 3 is positioned at the top of micro-crystal glass lampshade body 1, and high-power radiating light source is fixedly mounted in the micro-crystal glass lampshade body 1 formed cavity by this installing port, and high-power radiating light source links to each other with the external power electricity.Light radiation mouth 4 is positioned at the bottom of micro-crystal glass lampshade body 1, during the light source operate as normal, part electric energy is transformed into luminous energy, and after the 2 high efficiency reflections of light source reflecting layer, radiate by light radiation mouth 4 again, light radiation mouth 4 places are connected to other optical elements, make the light beam of radiation narrower, and uniformity is better.Thereby work light as the function admirable of data projector, back projection TV etc.
The beneficial effects of the utility model are: high heat, safe and reliable that (1) is high temperature resistant.Owing to adopted the body of devitrified glass as lampshade, be rapidly heated and high temperature high when hot, not easily broken, thereby the safety of components and parts around having guaranteed.(2) efficiency of light energy utilization height, radiation effect is good.Utilize the coating effects of high reflectance, highly improved the utilization rate of luminous energy.
Because above-mentioned advantage, the utility model is widely used in the lampshade equipment of high-power radiating light sources such as data projector, back projection TV.

Description of reference numerals:
Micro-crystal glass lampshade body 1 light source reflecting layer 2 light source installing ports, 3 light radiation mouths 4
The specific embodiment
Below in conjunction with accompanying drawing, specifically describe embodiment of the present utility model.
As shown in Figure 1, a kind of micro-crystal glass lampshade, by micro-crystal glass lampshade body 1 and light source reflecting layer 2, light source installing port 3, light radiation mouth 4 are formed, micro-crystal glass lampshade body 1 can be different shapes such as taper shape, bowl-type, hemispherical, and light source reflecting layer 2 fits tightly the inner surface at micro-crystal glass lampshade body 1.Devitrified glass can be high temperature resistant high warm, can be up to 700 degree Celsius, and light source reflecting layer 2 is made by the plating dura mater material of high reflectance.High power light source is fixedly mounted on the inner surface of micro-crystal glass lampshade body 1 by the light source installing port 3 of micro-crystal glass lampshade body 1, high power light source links to each other with the external power electricity, during the light source operate as normal, part electric energy is transformed into luminous energy, and after the 2 high efficiency reflections of light source reflecting layer, radiate by light radiation mouth 4 again, light radiation mouth 4 places are connected to other optical elements, make the light beam of radiation narrower, uniformity is better.Thereby work light as the function admirable of data projector, back projection TV etc.
