  1. Competing goods analysis

Most of the explosion-proof lamps and explosion-proof tri-proof lamps on the market are made of incandescent lamps, fluorescent lamps, high pressure metal gas discharge lamps and other lamps. This kind of lamps has mature technology and comfortable vision, and is widely used in indoor and general lighting, outdoor work lighting, but its disadvantages are obvious when working lighting.

  • Poor environmental adaptability, it often fails to work normally in a low temperature environment;
  • The safety factor is low, especially for gas discharge lamps such as metal halide lamps. The temperature of the lamps is high during operation, which is easy to become a hidden danger of safety accidents;
  • There are many faults and maintenance is difficult. Once the lamp is damaged, it cannot be repaired in time, which will seriously affect the safety of night production;
  • Poor vibration resistance and easy to damage. For example, the drilling offshore equipment has strong vibration, especially during the relocation process. The lamp tubes made of glass are often damaged and need to be replaced in large quantities, resulting in a lot of manpower and material loss, and mercury vapor and broken glass are returned to the environment. Cause harm;

With the continuous development of social productivity, LED technology continues to make breakthroughs. At present, white LEDs with luminous efficiency above 120Lm/W have been mass-produced. It has become the fourth generation of electric light sources after incandescent lamps, fluorescent lamps, and high-pressure metal gas discharge lamps, and is called the ultimate form of electric light sources.

The lamp beads used in the CESP explosion proof LED linear lamp LN series are high-quality LM80 certified chips, with a color temperature of 6000K and a color rendering index greater than 70. It can present colors and details more accurately than high-pressure sodium lamps or mercury vapor lamps. The luminous efficiency is as high as 140LM\W. such as the 50W hazard-area LED Linear light can produce 5500LM, 90° or 120° beam angle, which can meet the requirements of industrial lighting.

The copper-free aluminum alloy lamp body is powder-coated, which not only increases the strength and durability of the shell, but also improves the beautiful appearance. The combination of special heat dissipation design and LED technology helps the line lamp achieve an excellent rated life of 50,000 hours and an environmental adaptability of -40-+55°C.

The shell glass is made of high-strength tempered glass, which has been tested by internal pressure and hydraulic pressure. The anti-corrosion grade is WF2 and the IP grade is IP66. And this series of hazardous environment linear lights have multiple voltage capabilities and can work under 100-277 VAC, 50/60Hz without any special ballasts.

In general, this series of LED explosion-proof lights fixture are beautiful in appearance and powerful in function. They can accept ceiling, hoisting, pole mounting, wall mounting and other installation methods. They are very suitable for wastewater treatment, oil and gas refineries, drilling rigs, petrochemical facilities, food and beverage facilities, tunnels, outdoor wall and stanchion mounted general area lighting, and where flammable vapors, gases, ignitable dusts, fibers or flyings are presen.

  1. Product Performance Analysis

The first choice to replace traditional fluorescent lamps.

Explosion Proof LED Lights

CES-EX-LN-02P is a explosion proof tri-proof lamp with UL certification for Division system and ATEX/IECEX certification for Zone system. It can be used in hazardous environments such as Class I, Division 2, Groups A, B, C and D. , And used in hazardous environments such as Zone 1&21, Zone 2&22, it is the only explosion-proof lamp in the line lamp series with North American and European standards. It is the most cost-effective linear lamp in CESP. Its mask can withstand 4J impact. The upper temperature limit can reach 130°C. It has better corrosion resistance and is suitable for lighting with lower installation heights. It is the first choice to replace traditional fluorescent lamps.

Explosion Proof Lamp

CES-EX-LN-02N is a Division system with UL certification of explosion-proof linear lighting, which can be used in hazardous areas such as Class I, Division 2, Groups A, B, C and D; although the appearance is the most in the LN series a compact linear lamps, but still strong, the design of toughened glass is impact resistant, and the thickness of 6mm can withstand the impact of 4J. It is very suitable for lighting with lower installation heights, and it is an alternative to traditional fluorescent lamps, incandescent lamps and other lamps. The product of choice.

Explosion Proof LED Lights

The following is a comparison of explosion-proof signs and parameters of different systems of LN series linear lights.

  1. Product appearance and naming analysis

CESP's explosion-proof lights are mainly gray in appearance. From the appearance, gray explosion-proof lamps are more beautiful and atmospheric, and adapt to the lighting environment of industrial areas, and meet the needs of target consumers for appearance colors. The name of the LN series is also simplified from the word Linear. The following is the naming connotation and nameplate analysis of each lamp.

  1. other aspects of analysis

In terms of parts procurement and supply chain, while implementing localization, it actively promotes the globalization of the domestic parts industry. The parts of explosion-proof lamps are completely purchased by manufacturers in global model factories, and the parts are guaranteed to be of high quality. During the design and production, the power supply cavity and the light source cavity were adjusted according to the explosion-proof certification requirements of different regions, and the heat dissipation system specially designed by industrial designers was used to enhance the safety performance of the explosion-proof linear lamp.

And with the continuous research and development of products, LN series explosion-proof lamps have also derived derivative products. If the customer needs the emergency function of the strip light, and wants to not affect the original installation method, you can choose CES-EX-LN-02P, built-in emergency power supply, this explosion-proof linear light neither installs nor affects the appearance, and The emergency time is around 90min,If the customer has no specific requirements for the installation method, you can also choose CES-EX-LN-02N series lamps or CES-EX-LN series explosion-proof lamps, add an independent emergency power cavity to place emergency drives and batteries, and the minimum can be used for 90 minutes, with emergency power 12W; Or customers who want better wiring and cost-saving, they can also choose CES-EX-LN-02P, which can output the wires at the same time, which perfectly solves the customer's customized needs.
