[Concept] Lamps not light shines on the surface of the work and life of the light emitted in the course of the reflected a reflector. ======================== 【Material functions] ------------------ 1 [reflective rate] Mainly depends on the material, such as reflective material reflective, low luminous decay, etc. directly determine the quality of the reflector. ------------------ 2 [shape] Mainly refers to the angle of light reflection, decided reflectors on the processing power of the light source non-direct light. ------------------ In summary, the material and shape of the reflector determines the efficiency and output luminous flux of the lamp output. ======================== [Use of] The main use of the U-shaped or spiral energy saving lamps, fluorescent lights, street lights, LED lights, induction lamp, etc.. ======================== Test ------------------ 1, the UV light intensity of the test method UV-340B UV intensity meter reflector, polished aluminum plate installed on the ward Reflector UV lamp 56 Reflector UV lamp 34 and 51 stainless metal reflectors monitoring. ------------------ 2, the UV light intensity test results 0." f="Polished aluminum sheet reflector of UV light intensity with Reflector UV lamp intensity significant difference (P <0. 01), and installed stainless steel with polished aluminum plates of different metal materials for UV intensity was no significant difference (P> 0. " d="抛光铝板制成反光罩的紫外线灯强度与无反光罩紫外线灯管强度有显著性差别(P < 0. 01) , 而装不锈钢与抛光铝板不同金属材料对紫外线强度无明显差别(P > 0.">Polished aluminum sheet reflector of UV light intensity with Reflector UV lamp intensity significant difference (P <0. 01), and installed stainless steel with polished aluminum plates of different metal materials for UV intensity was no significant difference (P> 0. 05) Polished aluminum ultraviolet lamp with no significant difference reflectors both the intensity of the UV lamp excellent rate. Excellent rate of both the intensity of the UV lamp and the stainless steel reflector with polished Aluminium reflex was no significant difference. According to the principle of reflection of the light, using the reflector, so that the increase in optical density. The 254nm wavelength light is also increased. Any metal can occur by the light irradiation the photoelectric effect. However, for a variety of metals, such as zinc, copper, iron, platinum and the like, to use ultraviolet light irradiation Caixing. Negative charge generated by the photoelectric effect is the electron, the electron absorption energy transition to a higher energy orbit after an excited state, when it is unstable, it can also transition to a lower energy orbit, and released with a certain the photon energy, that is, give off light, visible light, infrared, ultraviolet light it emits. Reflectors excellent rate than the strength of the reflector. ======================== [Role] 1 in order to improve UV germicidal effectiveness, 2 can extend the service life of the UV 70 LW ö cm2, 可继续使用, 减少资源浪费。" f="The same lamp reflectors <70 LW ? cm 2 (should immediately adjust lights), fitted with reflectors strength> the 70 LW ? cm2, may continue to be used to reduce the waste of resources. " d="同一灯管在无反光罩时< 70 LW ö cm 2 (应马上调灯) , 装上反光罩后强度> 70 LW ö cm2, 可继续使用, 减少资源浪费。">The same lamp reflectors <70 LW ? cm 2 (should immediately adjust lights), fitted with reflectors strength> the 70 LW ? cm2, may continue to be used to reduce the waste of resources. 3. Improve the utilization of the light of lamps, lighting efficiency is greatly improved. ======================== 【Common type] ------------------ [U-type or screw-type energy-saving lamps reflectors] On many occasions, we can see the energy-saving lamps, almost every energy-saving lamps are reflectors, energy-saving lamps, light-emitting peripheral almost book spherical especially in the use of the process of the entire light mall light brightness is very high , in order to make the goods more attractive. 2 more than 60% of the energy saving lamp, the reflective effect of the light reflector bears. 3, but now the reflectors cohabitation, the main plating reflective layer oxidation quickly, the light fades quickly. Really durable resistance to the light fades very little, for several years the life of the energy-saving lamps and commercial renovation a few years of life, can basically. ------------------ Street light reflectors Mainly refers electrodeless lamp, metal halide lamp, sodium lamp reflector: high power of these lamps and light intensity. General use in the warehouse, road, landscape, the most common source of public outdoor. 3 due to the use of surface distance from the light of these lamps is relatively high, the light source can be directly on the use surface, is very small, such as lights, 12 meters high, the light source can be directly on the road surface is less than 15% of luminescence, rely on more than 85% of the light reflector to reflect, and to improve the utilization of light, now best street light reflectors can make the lamps light efficiency reached 60%. ------------------ [Fluorescent light reflectors] 1. Fluorescent lamp daily life, especially the most frequently used fixtures factories, businesses and schools, hospitals, but many do not use reflectors. 2 fluorescent reflector with fluorescent use, improve the utilization of the fluorescent light is emitted, under normal circumstances, the lamp is placed at the top of the room, the divergence of the angle of 360 degrees of the light around the lamp, only 120 degrees of which about one third of direct exposure to working or living surface use, scattered light to a large majority of other places to waste; 3 in order to improve the utilization of light lamps, under normal circumstances will give light and a reflector or reflector. ========================
