Abstract
The utility model relates to a ceramic material reflecting apparatus in illuminator technology sphere, which comprises a cup or a cover, and a bulb installing hole. The utility model is characterized in that, the apparatus is made of polycrystalline and polyphase ceramic material, and a layer of transparent white glaze (3) is smeared on the inner surface of the cover (1), which forms a smooth reflecting surface (4) and a reflecting interface(5). Compared with the prior art, the utility model can provide high grade illumination with higher light flux in a certain angle range, less ultraviolet content, and more uniform and soft rays. The sintered ceramic material for glazing can be made of ordinary metasilicate ceramics or compact oxide ceramics, which can provide mirror reflection and diffuse reflection for visible light, and absorption for ultraviolet. After glazing, the transparent glaze layer and interface can also provide mirror reflection, diffuse reflection, transmission, and enhancive reflection for visible light. When in glazing, the specular reflectance of the glaze surface can be increased by quick cooling or Titania addition.
Description
[technical field]
The utility model relates to the lighting device technical field, specifically a kind of ceramic material reflex reflector, i.e. reflector or reflection shield.
[technical background]
In field of illuminating lamps, the reflector of existing reflection-type lighting or the reflective metal materials such as aluminium alloy or steel alloy of being covered with, this is to utilize fine and close smooth metal surface that the minute surface reflex of visible light is carried out work.This reflector or reflection shield exist yielding, easy oxidation and cause light resistance poor, temperature height in the time of can absorbing visible light and cause work, and light loss is big, and to the poor insulativity of heat and electricity, light is dazzling and to shortcomings such as Ultraviolet rays protection effect differences.
Plate metal reflector layer or other medium reflective membrane as reflector layer at glass surface with methods such as plating, chemical plating or high temperature depositions.Its shortcoming is: cost height, easily oxidation, easily comes off and causes light resistance poor, and temperature height during work, impact resistance is poor.
Plate metal reflector layer or other medium reflective membrane as reflector layer on high-molecular organic material surface with methods such as plating, chemical plating or high temperature depositions, its shortcoming is cost height, yielding, easy oxidation, easily comes off and cause light resistance poor, temperature height during work, make the easily aging embrittlement of matrix material, poor to the Ultraviolet rays protection effect.
Plate metal film as reflector layer at the ceramic material matrix surface with methods such as plating, chemical plating or high temperature depositions, its shortcoming is cost height, easily oxidation, easily comes off and cause poor durability.
Will be after the glass surface sandization as reflective surface, its shortcoming is the light transmittance height, reflecting rate is low, and diffuse reflection all takes place reflection ray, the orientation uniformity is poor, range is short, the Lamp cup temperature is very high during work.
The sintering of normal silicate pottery and dense oxide pottery and surface glazing technology are all very ripe at present, be widely used in daily utensil and design, very extensive use is also being arranged aspect electronics, electrical equipment and the high-tension electricity, be used as lamp holder, lamp socket and electric(al) insulator in field of illuminating lamps.These application all are machinery and the electrical properties that has utilized ceramic dielectric, and the good optical performance that ceramic material has all is not applied.
Ceramic material is as a kind of inorganic dielectric material, it is a kind of insulating materials of broad stopband, and do not absorb visible light basically, but can absorb ultraviolet light, the insulating properties of comparing it with metal are much higher, absorptivity to visible light is much lower, and also much lower to heat and ultraviolet conduction, machinery and chemical stability are much better; Compare with macromolecular material, its reflecting rate is much higher, and is high temperature resistant, antioxygenic property is much better; With the glassy phase ratio, it is all low to the absorption and the transmission of visible light, and the heat conduction is also low, and reflecting rate is much higher, and impact resistance is also high.
[summary of the invention]
The purpose of this utility model is big in order to obtain in certain angle luminous flux, light is evenly soft, contain the few high-quality illumination of ultraviolet ray, a kind of reflex reflector made from the ceramic material of glazing is provided, it is all higher than the illumination quality and the light efficiency of existing Reflecting lamp cup or lampshade, and machinery and good electrical property, temperature is low during work, light resistance good, low cost of manufacture.
For achieving the above object, design a kind of ceramic material reflex reflector, its structure is cover or the cup-shaped groove that adds upper bottom portion installation bulb.Its outward appearance as depicted in figs. 1 and 2, cross-section structure is as shown in Figure 3. cup cover be shaped as parabolic cup-shaped or cone lampshade or four sides prismatic lampshade or semicircle lampshade or globe holder or cylindrical lampshade.It adopts polycrystalline heterogeneous sintering ceramic material to make matrix (1), and it has diffuse reflection and scattering process to light.
The transparent white glaze (3) of inner surface last layer of cup cover, its effect has: form smooth reflecting surface (4), make the specular reflectivity height of cup cover; Wherein particle and micropore have scattering process to light; Form interface (5) with ceramic matrix (1), in sintering process, glaze can be filled the pore and the crystal boundary on ceramic material (polycrystalline is heterogeneous) matrix (1) surface, and the polishing grain surface, make interface (5) become a smooth reflecting surface, light is had minute surface reflection and diffuse reflection effect; If matrix (1) is enough fine and close, transparent white glaze layer (3) is enough thin, then can form and increase reflective film, and the interference of light effect is strong, improves the reflectivity of long wavelength light, makes light softer.
The transparent white glaze or the colored glaze (2) of outer surface last layer of cup cover and groove can play beauty function, and the partial reflection effect is also arranged.
In sum, sintered ceramic material (polycrystalline is heterogeneous) matrix has the diffuse reflection effect to light, and the transparent white glaze of inner surface has minute surface reflection, scattering and transmission effect and increases reflex light; There are minute surface reflection and diffuse reflection effect in the interface to light; The transparent white glaze of outer surface has reflection and scattering process to light.Minute surface reflection makes light orientation high conformity, light efficiency height, diffuse reflection and increase reflection and then make light more even soft.
The utility model is compared with prior art, can obtain in certain angle luminous flux bigger, contain ultraviolet light still less, the more even soft high-quality illumination of light.And its technology cost is lower, and the product light resistance is good.
