How to choose the right LED UFO high bay light?
Due to the characteristics of its shape, the LED circular mining lamp is also known as the UFO mining lamp. At present, LED circular flying saucer mining lamp products have been very mature. Small shape, high light efficiency, can meet the requirements of a variety of indoor and semi-indoor places. Generally, people will link the LED circular UFO mining lights with the lighting of factories and warehouses. In fact, it can be widely used in many more places. For example, school auditoriums, toll stations, indoor stadiums, large supermarkets, car showrooms and so on.
The important structure of LED UFO mining lamp
The main structural feature of the LED circular UFO mining light is compact. Compared with the traditional mining shed, it is not only very small in size, easy to transport and install, but also light in weight and not easy to occur safety accidents. LED circular flying saucer mining light is mainly composed of the following parts:
1. LED chip
The structural design of the LED circular UFO mining light is to enable the LED chip to dissipate heat quickly and effectively during the working process. The performance of the LED chip will affect the luminous efficiency, light decay and life of the entire lighting fixture. The circular luminous surface can maximize the lighting range, and the ground illuminance is relatively uniform.
2. Heat sink
LED chip will heat when working, overheating will affect the life of LED chip. Therefore, the heat sink design of the LED circular UFO mining lamp is to allow the LED chip to dissipate heat in time and maintain efficient and durable lighting. The material of the heat sink is generally aluminum alloy. Aluminum alloy has good thermal conductivity. Magnesium aluminum alloy is a new type of heat dissipation material in recent years, magnesium aluminum alloy is characterized by light weight and good heat dissipation performance.
3. Light distribution
Optical design is a very important part of lighting. Different installation heights and ground illuminance requirements require different optical designs. Under the same luminous efficiency, the power and light distribution of the LED circular UFO mining lamp will affect the ground illuminance, and the greater power means more power consumption, so the light distribution can play a better role in this case. The common light distribution of the LED circular UFO mining lamp is 120°, and the narrower light distribution is 90° and 60°. If your installation height is higher than 5m or requires a ground illuminance greater than 200lux, it is best to choose a narrow light distribution to meet lighting needs.
How to choose LED round ufo mining light
At present, there are many kinds of LED circular UFO mining lights on the market, how to choose the right one? The following four aspects can help you determine whether this lamp is suitable for purchase and use.
1. Light efficiency
Generally speaking, high light efficiency means better energy saving. It is believed that under the same ground illuminance requirements, the higher light efficiency of the LED circular UFO mining lamp means that the same ground illuminance can be achieved with lower wattage. It has a very intuitive impact on enterprise energy saving. However, higher light efficiency does not mean better. First of all, high-efficiency lighting fixtures can also mean faster light decay. Therefore, you need IES LM-80, IES LM-79 and L70 reports to help you determine whether the LED chip can maintain high luminous efficiency for a long time. On the other hand, it is also necessary to understand the UGR of LED circular UFO mining lamps. Higher light efficiency usually means higher UGR value. If the UGR value is too high, it will lead to an uncomfortable visual experience.
2. Performance
Good heat dissipation performance and lighting performance in different extreme environments are important criteria for judging the quality of LED circular UFO mining lamps. The temperature rise test report can give a good feedback on whether the heat dissipation performance of the LED circular UFO mining lamp is excellent. If the temperature rise test report shows that the LED chip temperature is too high, it will seriously affect the performance of the lamp, resulting in serious light decay of the lamp. At the same time, the corrosion resistance and impact resistance levels also need to be professionally tested to ensure that the LED circular UFO mining lamp can be used safely. High and low temperature impact test and high and low temperature start-up test can show the performance of lamps in extreme environments.
3. Certification
Since each country has different requirements for LED circular ufo mining lights, it is necessary to know what certifications are required for lighting in your country. Products that meet the certification can guarantee safe use in the country. At the same time, some special applications require special certification. For example, food processing plants need to pass the certification of domestic food processing management agencies, and chemical plants need explosion-proof certification.
4. Intelligent control
LED lamps have the characteristics of environmental protection and energy saving, if the lamps are equipped with intelligent control system, energy saving efficiency will be further improved. Usually in Europe, LED circular UFO mining lamps require DALI dimming function or 1~10V/0~10V dimming function. If your project is a warehouse, you can also consider equipped with a motion sensor for the LED circular UFO mine, which can sense the movement of people and goods at any time to turn on or off the light. If you need to adjust the brightness of the light according to the ambient illumination, you can also choose the LED circular UFO mining lamp with the illumination sensing intelligent module, so that your indoor place can keep the illumination level unchanged at any time.
At present, most of the LED circular UFO mining lamps have a 5-year warranty, so if you choose the product according to the engineering needs and the quality of the LED circular UFO mining lamps, the lamps can work for a long time.
