The invention further increases the protection grade and the maintenance factor of the lamp and achieves the purposes of safe electricity utilization, energy saving, reduced investment and green lighting.
Description
Affiliated technical field:
The present invention relates to a kind of light fixture that can improve light fixture degree of protection and maintenance factor, especially as the light fixture that uses in the road lighting.
Background technology:
The degree of protection of light fixture mainly is meant the dust and water protection grade.At present, the protective of most of light fixture is relatively poor, and degree of protection maintains about IP33, insect, water droplet, dust and other impurities enter in the light fixture easily, easily cause danger such as electric shock or short circuit, the reflecting effect of reflector also is affected simultaneously, and the maintenance factor of light fixture descends.The light fixture maintenance factor is meant that lighting device used after the regular period, when the lip-deep average illumination of regulation or mean flow rate are newly installed under the same conditions with this device on same surface the ratio of resulting average illumination or mean flow rate.The size of light fixture maintenance factor depends primarily on the material and the process of reflector and transparent glass.
The reflector of tradition road illuminating lamp adopts aluminium sheet drawn and stamping forming operation mostly, and the moulding rear surface needs through chemical polishing and anodized, and carries out distilled water or pure water packaging technology on the oxide layer surface and handle.The such selection and the process of surface treatment of reflector make that the reflector efficiency of reflector is low, and reflection coefficient has only about 70%.The thermal coefficient of expansion of rafifinal is 23.0 * 10
-6/ K.When the reflector expanded by heating, its inner reflective membrane can produce the slit, and the light of reflection reduces.If reflector expands repeatedly for a long time and shrinks, can cause the aging of reflectance coating, further reduce reflection coefficient, the light fixture maintenance factor also has only about 0.5.Generally speaking, the sealing between reflector and the transparent glass often adopts rubber cushion to realize, the water proof and dust proof effect is relatively poor.
High-boron-silicon glass is a characteristic of utilizing glass to conduct electricity under the condition of high temperature, by realizing processing glass melting through vanguard technology in the inner heating of glass.High-boron-silicon glass has following performance: low thermal expansion (thermal coefficient of expansion: (0～300 ℃) 3.3 ± 0.1x10
-8/ K), high temperature resistant (820 ℃ of softening points, high thermal stability, the heat-resisting temperature difference are greater than 270 ℃), high transmission rate (can reach 90%).Select for use high-boron-silicon glass as the reflector case material, when light is injected reflector, because thermal coefficient of expansion is lower, the level of stretch of material is very little behind the expanded by heating, thereby it is little to reflect film formed slit, to the reflectivity height of light, and is difficult for causing that because of the contraction of expanding repeatedly for a long time reflectance coating is aging, can improve the maintenance factor of light fixture greatly, compare the very big advantage that accounts for fine aluminium.Transparent glass because high-boron-silicon glass self has higher light transmittance, selects for use it as the transparent glass material as last parts of light ejaculation light fixture process simultaneously, can improve the efficient of light fixture simultaneously.
Summary of the invention:
Main purpose of the present invention is: adopt new material and new technology to make the light-source chamber of light fixture, improve the maintenance factor of light fixture degree of protection and light fixture.
The present invention is solved over the technical scheme that light fixture existing problems are taked and is: the structure in the light fixture comprises light-source chamber and electric apparatus chamber two parts, adopts new material and new technology to make the light-source chamber of light fixture, and light-source chamber mainly is made up of reflector, transparent glass.It is material that the reflector of light-source chamber and transparent glass all adopt high-boron-silicon glass.The reflector outer surface of light-source chamber plates one deck reflectance coating, and reflectance coating is made up of reflector layer, external protection.Reflector layer is plated in housing outer surface, and external protection is close to reflector layer, be coated in reflector layer above.It is material that reflector layer adopts argent, and it is material that external protection adopts the anti-vulcanizing agent of a kind of silver.Use adhesion technique directly reflector and transparent glass to be sealed then.
The invention has the beneficial effects as follows:
It is material that the housing of reflector described in the present invention adopts high-boron-silicon glass.High-boron-silicon glass has very low thermal coefficient of expansion, and under 0～300 ℃ of condition, this coefficient is 3.3 ± 0.1x10
-8/ K, and its energy long-term work under 450 ℃ of high temperature, light transmittance is very high, reaches more than 98%, can improve the light fixture starting efficiency greatly.Because high-boron-silicon glass is adjustable to extremely low thermal coefficient of expansion, the level of stretch of comparing material under hot conditions with rafifinal is little, thereby it is little to reflect film formed slit, reflectivity height to light, can improve the maintenance factor of light fixture, reach more than 90%, and be difficult for comparing the very big advantage that accounts for fine aluminium because of the long-time contraction of expanding repeatedly causes the aging of reflectance coating.
Reflectance coating described in the present invention is made up of reflector layer, external protection.Reflector layer is plated in housing outer surface, and external protection is close to reflector layer, be coated in reflector layer above.It is material that reflector layer adopts argent, and external protection is a kind of anti-vulcanizing material.The reflecting layer is an argent coating, and main effect is to be used for reflection ray, because its good non-oxidizability, the reflectivity decay is slower, and is even after long-time the use, still have reflecting effect preferably, very little to the influence of light fixture starting efficiency.But silver has very strong affinity to sulphur, can directly be combined to black chemical substance Ag with sulphur during heating
2S so external protection adopts a kind of anti-vulcanizing material, is mainly used to prevent that the silvering of reflector from curing, and guarantees the reflectivity of reflector.
Owing to adopt the technology of back of the body plating reflectance coating, silvering can not come off because of using for a long time, avoids the consequence that causes the reflector reflection efficiency to descend and reduce the light fixture maintenance factor.
It is material that transparent glass described in the present invention adopts the high-boron-silicon glass of tempering, has advantage high temperature resistant, high transmission rate.Compare with simple glass, its light transmittance reaches 90%, and the light transmittance of simple glass has only about 80%, therefore can improve the efficient of light fixture.
Reflector and transparent glass material be all after tempering is handled among the present invention, even the reflector fragmentation becomes the fractionlet of no acute angle at once, reduced the injury to human body.
Reflector and transparent glass adopt adhesion technique among the present invention, and the two is sealed fully, prevent that dust, water droplet from entering in the light fixture, improve the degree of protection of light fixture, reach more than the IP65.The workload that adopts the light fixture of this degree of protection can accomplish to reduce effectively maintenance improves the maintenance factor of light fixture, helps energy savings.
