FAQs | LIGHTNINGCURE LC-L5G: Linear irradiation type UV-LED units

LC-L5G are high output and adopting proprietary air-cooling method.

Conventional UV-LED light sources cannot achieve high-throughput, but LC-L5G can achieve it.

Q01. What is the temperature of the lightsource unit during operation?


The typical value is about 40 ℃ to 50 ℃ (about 60 ℃ in localized sections) when the operating ambient temperature is 25 ℃, although this differs depending on the particular light source model.

Q02. Are there classifications like laser classes?


LEDs are not classified as lasers but are instead classified under IEC 62471 "Photobiological safety of lamps and lamp systems." A risk group determination is made for each light source model.

Q03. Is customization possible?


We will consider your request based on the specifications and quantities, so please feel free to contact us.

Q04. Are there any other requirements for operating the light source besides the light source itself?


The items shown in the connection diagram are required.
his light source is designed to operate by external control, so power supply and cables are required.

Q05. Is a cooling exhaust duct required?


No cooling exhaust duct is required because the mounted cooling fan is basically sufficient for cooling.
However, if used in an enclosed space, the exhaust air from the light source might raise the operating ambient temperature. In that case a cooling exhaust duct is required depending on the environment where installed.

Q06. Does this light source produce ozone?


No, it does not produce ozone.

Q07. Does replacing a metal halide lamp with a UV-LED light source change the working environment?


UV-LED light sources emit less heat than metal halide lamp, so the temperature in the working environment will likely be lower, although this depends on how tightly the space is enclosed or how the air conditioning cools the working environment.

Q08. Are there any thermal effects on the target objects?


The thermal effect of UV-LED light sources on the target object is less than that of metal halide lamps which emit heat rays. However, target objects might be thermally affected depending on their materials or the wavelength and light intensity.

Q09. How can light intensity be measured or monitored?


We recommend using Hamamatsu UV power meter to measure or monitor light intensity.
Light intensity can also be measured or monitored with a calibrated UV power meter owned by the customer.

Q10. How should maintenance be performed?


Optional parts specified by each model can be replaced on site.

If other maintenance or troubleshooting becomes necessary please return the light source unit to us for servicing.

Q11. Is it possible to evaluate the performance of light source?


We have a demo unit available for this task, so please feel free to contact us for detailed information.

Q12. What precautions should be taken during use?


UV-LED light sources emit strong UV light harmful to the skin and eyes, so be sure to wear protective equipment when handling.
Install UV-LED light sources in equipment designed to prevent UV light leakage.
