What is a Commercial Hood?

Reflector is a kind of reflector that is often used, which can greatly improve the light utilization rate of the luminaire and greatly improve the efficiency of the luminaire. The reflectivity of the reflector mainly depends on the material. For example, the reflectivity of the reflective material is high, and the light decay directly determines the quality of the reflector.

Reflector

Reflector refers to a kind of reflector that reflects the light from the light source that cannot shine on the working and living surfaces during the use of the lamp. Mainly used in U-shaped or spiral energy-saving lamps, fluorescent lamps, street lamps, LED lamps, induction lamps, etc. The shape of the reflector mainly refers to the angle of reflection of light, etc., which determines the ability of the reflector to handle indirect light from the light source. In summary, the material and shape of the reflector determine the output efficiency and output luminous flux of the lamp.

Energy-saving lamp reflector

On many occasions we can see U-shaped or spiral energy-saving lamps. Almost every energy-saving lamp will have a reflector. The light-emitting periphery of the energy-saving lamp is almost spherical. During the entire use of light, especially the brightness of the mall Very high to make the product more attractive. The reflector is responsible for reflecting the light of more than 60% of the energy-saving lamps. However, the reflectors on the market are mixed, mainly electroplated reflective layers, which oxidize quickly and decay rapidly. Very few really can last long anti-light decay, for the life of energy-saving lamps for several years and commercial decoration for several years, it is basically okay.

Street light reflector

Mainly refers to electrodeless lamps, metal halide lamps, sodium lamp reflectors: these lamps have high power and light intensity. Generally used in warehouses, roads, and landscapes. It is the most common light source in public outdoor. Due to the relatively high distance from these lamps to the use surface of the light, very few light sources can directly shine on the use surface, such as street lamps, 12 meters high, the light source can directly shine on the road less than 15% of its light emission, which is 85%. More than% of the light must be reflected by the reflector to improve the utilization rate of the light. The best street lamp reflector can make the light efficiency of the lamp reach 60%. The street lamp reflector developed by Dongguan Deep Green Energy Saving Technology Co., Ltd. can make the light efficiency of the lamp reach about 92%, which greatly improves the energy saving opportunities of the street lamp. Why is dark green energy saving so loyal to researching reflectors? Street lamps in China consume hundreds of billions of electricity bills each year and become a major part of public expenditure. At the same time, the state has begun financial subsidies for high-pressure sodium lamps, allowing excellent reflectors to be used with high-pressure sodium lamps, saving more than 50% of energy, saving the country A lot of money.

Fluorescent lamp reflector

Fluorescent lamps are the most frequently used lamps in daily life, especially in factories, enterprises, schools and hospitals, but many do not use reflectors. Fluorescent reflectors are used in conjunction with fluorescent lamps to improve the utilization of light emitted by fluorescent lamps. Generally, the lighting lamp is placed on the top of the room, and the light diverges around the lamp at a 360-degree angle, of which only about one-third of 120 degrees directly shines into the work or The living surface is used, and other light is scattered to other places. Most of it is wasted. In order to improve the utilization rate of the light of the lamp, a reflector or a reflector is generally added to the lamp. As the fluorescent lamp is the most commonly used lamp for life and work, Therefore, the research of reflectors for fluorescent lamps has been professionally studied by many companies.

Fluorescent lamp reflector

1.Test method of UV lamp intensity

The reflector uses a UV-340B ultraviolet intensity meter to monitor the polished aluminum plate reflector UV lamps 56, reflectorless UV lamps 34 and 51 stainless metal reflectors installed in the ward.

2. Results of UV lamp intensity test

There is a significant difference between the strength of the UV lamp made of the polished aluminum plate and the strength of the UV lamp without the reflector (P <0.01), and there is no significant difference in the UV intensity of the different metal materials with stainless steel and polished aluminum plate (P> 0. 05)

There is a significant difference between the excellent and good intensity ratio of the polished aluminum plate UV lamp and the reflectorless UV lamp. However, there is no significant difference in the excellent and good intensity ratio between the stainless steel reflector and the polished aluminum reflector. According to the principle of light reflection, the density of light is increased by using a reflector. 254 nm light also increased. Photoelectric effects can occur when any metal is exposed to light. However, for many metals, such as zinc, copper, iron, platinum, etc., it is necessary to irradiate them with ultraviolet rays. The negative charge generated by the photoelectric effect is the electron. The electron absorbs energy and jumps to an orbit with a higher energy, and then becomes excited. At this time, it is unstable, and it can also transition to a lower energy orbit. The photon of energy, that is, the light that is emitted, includes visible light, infrared light, and ultraviolet light. Therefore, there is a higher rate of superiority of strength with a reflector than without a reflector. Install a reflector, one is to improve the effectiveness of ultraviolet sterilization, and the other is to extend the service life of ultraviolet rays. Without a reflector, the same lamp tube is <70 LW & ouml; cm 2 (the light should be adjusted immediately). The intensity after installing the reflector > 70 LW & ouml; cm2, can be used continuously, reducing waste of resources.
