The explanation of following embodiment is refer to the attached drawing, can be to the particular implementation implemented to example the utility model
Example.The direction and position term that the utility model is previously mentioned, for example, " on ", " in ", " under ", "front", "rear", "left", "right", "
It is interior ", " outer ", " side " etc., be only the direction and position with reference to annexed drawings.Therefore, the direction and position term used is to use
To illustrate and understand the utility model, and it is not used to limit the utility model.
Embodiment：
As shown in Figures 1 to 4, the utility model provides a kind of high temperature resistant UV light emitting structures, including the He of the barricade of resistance to UV 3
Quartz glass minute surface 1, the inner surface of the barricade of resistance to UV 3 are provided with one layer of high-temperature silica gel of resistance to UV 4, the quartz glass minute surface 1
Cover and coupled on the luminous zone surface of the barricade of resistance to UV 3, the surface of quartz glass minute surface 1 after gradually being plated provided with one layer of quartz glass vacuum
Face 2, coupling surface 2 connects with the barricade of resistance to UV 3 after the quartz glass vacuum gradually plates.
Quartz glass purity needs to ensure, 365nm UV transmitances are more than 95%；Quartz glass needs to do secondary Fresnel
Optical treatment, similar fly's eye effect is formed, allows the light extraction of light source to be more uniformly distributed；Exist 3. quartz glass vertically arrives UV barricades face passage
By secondary Fresnel processing after, can be irradiated to bonding silica gel UV need it is few as far as possible；4.UV barricades form shelves wall, allow UV
Light can not be shone directly into above silica gel；5. resistance to UV high temperature resistants silica gel must be able to ensure bonding force under 365nm violet exposures.
