Explosion proof<\/strong> LED tunnel lights: tunnel safety lighting core technology analysis and application practice<\/strong><\/strong><\/h1>\n\n\n\n
\"Explosion<\/figure><\/div>\n\n\n\n

First, <\/strong>Explosion proof<\/strong> LED tunnel lights in the tunnel environment core application scenarios<\/strong><\/strong><\/h2>\n\n\n\n

Tunnel as a semi-enclosed special traffic space, there are oil and gas volatilisation, dust accumulation and temperature and humidity fluctuations and other complex environments, conventional lighting equipment due to electrical sparks or structural failure triggered by potential safety hazards.<\/p>\n\n\n\n

With Explosion proof design, intelligent temperature control system and corrosion-resistant materials, Explosion proof LED tunnel lights can provide safe and efficient lighting in the following fundamental scenarios:<\/p>\n\n\n\n

1. oil and gas mixing high-risk areas: such as petrol stations in tunnels, vehicle breakdown detention areas, Explosion proof LED tunnel lights approved Exd IIB T4 <\/a>Explosion proof grade design, Explosion proof cavity can withstand 150kPa explosion pressure, blocking the internal arc leakage.<\/p>\n\n\n\n

2. construction and maintenance work area: the construction process probably produces methane and other combustible gases, lamps and lanterns need to have IP66\/IP67 protection level, with 316L stainless steel shell and anti-static coating, to prevent dust infiltration and static electricity build-up.<\/p>\n\n\n\n

3. High humidity and corrosive environments: coastal or high water table tunnels, Explosion proof LED tunnel lights using ceramic heat dissipation technology [alumina ceramic substrate], approved by ISO 9227 guidelines 2000 hours of salt spray test, to resist high humidity and chemical corrosion.<\/p>\n\n\n\n

4. Emergency evacuation channel: integrated lithium iron phosphate battery Explosion proof LED tunnel light can maintain \u2265 3 hours of emergency lighting after a power failure, to ensure the safe evacuation of personnel and repair operations.<\/p>\n\n\n\n

Second. Amasly Explosion proof\u00a0LED tunnel lights five technical advantages<\/strong><\/h2>\n\n\n\n

1. Intrinsic safety and Explosion proof\u00a0performance Explosion proof\u00a0LED tunnel lights Explosion proof\u00a0+ safety composite structure, surface temperature \u2264 80 \u2103 [T6 group], to avoid ignition of combustible gases in the tunnel [such as methane, gasoline vapour].<\/p>\n\n\n\n

Its Explosion proof cavity design is approved by CNEX\/PCEC, which meets the requirements of explosive environments of \u2161A, \u2161B and \u2161C.<\/p>\n\n\n\n

2. Energy efficient and long life luminous efficacy of 140 lm \/ W, 100W lamps and lanterns luminous flux of more than 11,000 lm, compared with 400W high-pressure sodium lamps, energy consumption reduced by 65%;<\/p>\n\n\n\n

LED light source life \u2265 100,000 hours, reduce maintenance frequency [such as 20 m high tunnel top maintenance costs reduced by 80%].<\/p>\n\n\n\n

3. Intelligent control and dynamic dimming with the help of DALI\/0-10V dimming system, combined with traffic flow, inside and outside the cave brightness sensor real-time adjustment of illumination.<\/p>\n\n\n\n

For example, the brightness of the entrance section is automatically raised to 200 lx during the day and lowered to 50 lx at night, so as to implement \u2018on-demand lighting\u2019 and save energy by more than 30%.<\/p>\n\n\n\n

4. Anti-vibration and environmental adaptability: IK10 impact-resistant lampshade and L-type anti-vibration bracket can adapt to the vibration of tunnel construction machinery; temperature resistance ranges from -40\u2103 to +80\u2103, which is suitable for high-altitude, extreme cold or high-temperature tunnel environments.<\/p>\n\n\n\n

5. Optical improvement and visual safety using asymmetric light distribution [120 \u00b0 beam angle] and batwing light pattern design, eliminating the \u2018black hole effect\u2019 and \u2018zebra effect\u2019, longitudinal brightness uniformity> 0.7, glare index TI <15%, to enhance the driver’s visual comfort. Comfort.<\/p>\n\n\n\n

Third. Explosion proof\u00a0LED tunnel lights selection and installation specifications<\/strong><\/h2>\n\n\n\n

1. Explosion proof grade: Exd IIB T4 [oil and gas environment] or Exd IIC T6 [hydrogen and other high-risk gases] is preferred. 2;<\/p>\n\n\n\n

2. Optical configuration: the entrance section adopts high-intensity concentrating lens (luminous flux concentration), and the middle section applies wide-angle floodlight (150\u00b0 coverage);<\/p>\n\n\n\n

3. Heat dissipation programme: ceramic substrate + fins convection heat dissipation, to ensure that the chip junction temperature \u2264 70 \u2103, to slow down the light decay [10,000 hours of light decay <5%];<\/p>\n\n\n\n

4. Installation guidelines: lamp spacing \u2264 8 metres, height from the ground \u2265 4.5 metres, tilt angle of 5 \u00b0 -15 \u00b0, to avoid direct shooting driver’s line of sight.<\/p>\n\n\n\n

Fourth, application cases: high-altitude tunnel lighting transformation<\/strong><\/strong><\/h2>\n\n\n\n

A tunnel at an altitude of 4500 metres of the original use of high-pressure sodium lamps, the annual failure rate of more than 60%, replaced by AMASLY Explosion proof LED tunnel lights:<\/p>\n\n\n\n

The average illuminance from 50 lx to 180 lx, accident rate decreased by 45%;<\/p>\n\n\n\n

The lamps are approved for 2000 hours of salt spray and -40\u2103 low temperature test, zero fault operation;<\/p>\n\n\n\n

Comprehensive energy consumption reduced by 70%, payback period of only 1.2 years.<\/p>\n\n\n\n

FAQ: Explosion proof\u00a0LED tunnel lights common problems answer<\/strong><\/h2>\n\n\n\n

Q1\uff1aDoes Explosion proof LED tunnel light need regular Explosion proof testing?<\/p>\n\n\n\n

Yes, the Explosion proof surface of the tunnel light needs to be tested every 2 years. It is necessary to implement the Explosion proof surface inspection and sealing test every 2 years, and submit the Explosion proof certificate to the safety supervision department for the record.<\/p>\n\n\n\n

Q2\uff1aHow to deal with the lamp surface oil adherence?<\/p>\n\n\n\n

We advocate the use of nano oleophobic coating lampshade, wipe with neutral detergent every month, prohibit the use of strong acid \/ alkali solution. Part of the model with the help of automatic cleaning function.<\/p>\n\n\n\n

Q3: What is the dimming range of Explosion proof LED tunnel light?<\/p>\n\n\n\n

Support 10%-100% infinitely dimmable, approved PLC or light sensor probe to implement dynamic control, to adapt to different time lighting needs.<\/p>\n\n\n\n

Q4: Can it be directly replaced on the existing high-pressure sodium lamp circuit?<\/p>\n\n\n\n

Need to verify the voltage compatibility [AC220V \u00b1 15%], advocating the addition of surge protectors and adjust the distribution circuit load.<\/p>\n\n\n\n
