Installation and maintenance of led explosion proof light

Explosion-proof lights should be checked from the nameplate and product manual before installation: explosion-proof type, category, level, group; protection level of the enclosure; installation method and requirements for installation fasteners, etc.

The installation of the explosion-proof lamp must ensure a firm fixation, the fastening bolts shall not be replaced at will, and the spring washers shall be complete. The dust-proof and waterproof sealing ring should be placed as it is when installing. Where the cable enters, the cable and the sealing gasket should be closely matched, the cross section of the cable should be round, and the surface of the sheath should not have defects such as unevenness. Excess inlets must be sealed according to the explosion-proof type, coated with 201 replacement anti-rust oil, and tighten the compression nut to seal the inlets. For led explosion-proof lights where there is strong vibration, use anti-falling rings to prevent the lights from falling off.


Safety! LED Explosion proof light

Explosion-proof LED lights are highly applicable in facilities where dangerous gases and dust are present. Confined spaces in such establishments entail numerous obstacles for workers, inspectors, and operators, due to the location’s isolated and unpredictable nature. Applying the right explosion-proof lights in a facility can greatly improve safety in the workplace and minimize risks related to fire hazards, explosions, and accidents.



60% Saving !–CESP LED carpark lighting system

CESP Lighting team was engaged to design and supply a lighting solution that complemented the architectural styling of the building and its surrounds,which include the applicable car park and pedestrian areas.

The CESP LED Carpark lighting offers uniform illumination and comfortably provides increased light levels for car parking areas.

After installation, the project already exceed the required light levels. The fittings were also supplied with DALI dimming, offering flexibility to reduce light levels during times of low use.



LED Carpark lighting upgrade

The facility manager called CESP LED team to make a site survey, which aims to develop an improved lighting solution for their carpark, and also be low maintenance and energy-saving. Car parks were traditionally poorly lit, and maintenance is a problem due to the height of the luminaires, which makes access difficult and costly.


In this case their whole existing lighting comprised 55 unit 400W SON’s mounted on the poles and wall. This arrangement gave poor illumination and spread, and with their lights left on all night the maintenance workload was a problem.

Throughout adopting LED technology this carpark was able to illuminate double the original car park area with a much more even light s. Further benefits of their switching to LED were that the light colour is much more representative of daylight, being 5700K in temperature, and so the overall lighting effect had been totally transformed.


In addition, the long life of LED means that maintenance is no longer a factor. The real added bonus to the customer though is that their total upgrade power consumption was actually halved although the illuminated area has doubled.


LED Sports Lighting

The Stadium owner wanted an energy-efficient lighting solution with zero light spill. As the tennis courts are built close to residential areas, the real challenge was to integrate the high light levels required for safety and comfort without negatively affecting residents living in the homes adjacent to the park. 

As light trespass was of utmost importance for this installation, it was critical to really direct the light onto the courts and not into the neighboring homes and yards. Our photometric designer worked with the consulting engineer to overcome this challenge by proposing the CESP LED floodlight installed at a zero-degree tilt. Having the specific optics to use in this case was what set CESP LED Flood light apart on this project, as we could deliver the light exactly where it was needed and protect the surrounding environment.

A total of 12pcs CESP LED floodlights were installed at a height of 10m on 6 poles. They ensure excellent visibility with high visual comfort, so players can enjoy the facilities when the sunsets.


LED explosion-proof light

LED explosion-proof lamp is a kind of explosion-proof lamp. Its principle is the same as that of the explosion-proof lamp, except that the light source is an LED light source, which refers to various specific measures adopted to prevent the ignition of surrounding explosive mixtures such as explosive gas environment, explosive dust environment, gas, etc. Measures the lamps. LED explosion-proof lamps are currently the most energy-saving explosion-proof lamps, widely used in oil fields-power plants-chemical plants-petroleum-troops.

One of the most important explosion-proof principles of LED explosion-proof lamps is to limit the temperature of the shell surface, the surface of the parts or the surface of the electronic components in contact with explosive gases and explosive dust, and to limit the temperature of the electrical contact surface below its minimum ignition temperature or ignition temperature. . LED explosion-proof lights used outdoors to need to use waterproof drivers. The LED explosion-proof lights used in gas stations need to be shockproof!

Classification of explosion-proof lamps


  1. Please refer to the national standards for the explosion-proof category, level, and temperature group of explosion-proof lamps.


  1. According to the explosion-proof type, it is divided into 5 main types: explosion-proof type, increased safety type, positive pressure type, non-sparking type and dust explosion-proof type. It can also be composed of other explosion-proof types and the above-mentioned explosion-proof types combined or composite and special types. .


  1. According to the type of electric shock protection, it can be divided into Ⅰ, Ⅱ, and Ⅲ categories. The protection against electric shock is to prevent the easy-to-touch parts of the explosion-proof lamp housing from electrifying, causing electric shock to the human body or touching conductors of different potentials to generate electric sparks and ignite explosive mixtures.


Class AⅠ—On the basis of basic insulation, all accessible conductive parts that are not charged during normal operation are connected to the protective grounding conductor in the fixed line.


Class BⅡ-Double insulation or reinforced insulation is used as a safety protection measure, without grounding protection.


Class CⅢ-Use a safe voltage with an effective value of not more than 50v, and no voltage higher than this value will be generated in it.


Class D0-only rely on basic insulation as a safety protection measure. The vast majority of explosion-proof lamps with electric shock protection type are Class I lamps, and only a few are Class II and Class III lamps. For example: all plastic explosion-proof lamps, explosion-proof flashlights.


  1. Classified according to the protection level of the enclosure: In order to prevent dust, solid foreign matter and water from entering the lamp cavity, touching or accumulating on live parts, causing flashover, short circuit or damage to electrical insulation, there are multiple enclosure protection methods to protect the electrical The role of insulation. Use the characteristic letter “IP” followed by two numbers to characterize the enclosure protection level. The first number indicates the ability to protect against people, solid foreign objects or dust. Divided into 0-6 levels. Explosion-proof luminaire is a kind of sealed luminaire, its dustproof ability is at least 4 or above. The second number indicates the water protection ability, which is divided into 0-8 grade.


  1. According to the classification of the supporting surface material of the lamp design: indoor explosion-proof lamps may be installed on many common combustible material surfaces, such as wooden walls and ceilings. They do not allow the temperature of the installation surface of the explosion-proof lamps to exceed the safe value. According to whether explosion-proof lamps can be directly installed on the surface of ordinary combustible materials, they can be divided into two categories.


One category is lamps that are only suitable for installation on non-combustible surfaces.


The other is the lamps suitable for direct installation on the surface of ordinary combustible materials, with marking symbols.


  1. According to the form of installation and use, it can be divided into fixed, movable, and portable.

Workshop Lighting Upgrade

With almost 250 luminaires across the SOP facility, CESP led highbay Lighting needed to produce an efficient and organised plan to convert the lighting system in the quickest and least disruptive way possible. This meant that precise lighting designs were created for every area, and an installation audit was a necessity for the operation team before the work began.

The biggest challenge for CESP Installation was the main factory area which housed 320 400w Metal Halide fittings. Due to the high ceilings and large machinery, CESP Installations required specialised access equipment to install the new system safely. New energy-efficient lighting was also introduced into the canteen, offices, reception, and testing Labs as well as corridors, toilets, and smaller rooms for tool cleaning and maintenance.

SOP Facility were able to achieve financial savings of over 65% with a return on investment of 11 months. This means that over the 5-year warranty period for CESP Lighting products.


Mitsubishi Logistics Lighting upgrade

Mitsubishi Logistics approached CESP Lighting with a focus on improving lighting levels in racking and operating areas in their facility in Dubai.

After free CESP Lighting audit,due to the facility changing uses, the layout of the lighting did not work and needed a complete overhaul. The lower racking areas were poorly illuminated by 2500 units 2*36W tube light. With the intention of vastly improving the light levels in these areas, CESP Installations replaced these 450 fittings with our market-leading 190+ Lm/W Highbays. The result was a dramatic improvement of levels and quality of light in the operating area. Despite the significant increase fittings, CESP Lighting’s solution still slashed 32% off their previous annual energy costs.

Working closely with Mitsubishi Logistics, our Lighting specialists advised that a PIR sensor would further reduce the quantity of wasted energy. This enabled a further reduction of 40% in operating costs – resulting in a total percentage saving of 72%! The client was thoroughly impressed with the seamless process from consultation to installation and said that the results speak for themselves.
