As the basic protective equipment for single-person lighting of firefighters, the quantity and quality of wear-resistant explosion-proof lamps reflect the economic strength, technological development level, fire-fighting equipment development level and fire-fighting strength of a country to a certain extent. With the development of the economy, it is more necessary to conduct research and analysis on the production and development of China's wear-resistant explosion-proof lighting in the current situation that the difficulty of fire fighting is increasing and the people's requirements for fire safety are getting higher and higher.

First, a brief history of the development of wear-resistant explosion-proof lighting

1, split headlights

The split-type principle is the same as the miner's lamp, which is mainly composed of a lamp cap, a cable, and a battery case; the split type requires the cable to connect the lamp cap on the helmet and the battery case on the waist, which binds the physical action of the firefighter.

2, integrated headlights

The integrated headlights have been developed in recent years. The battery is packaged in the lamp holder. The headlight type needs to be installed on the front end of the helmet. The fire helmet without the card seat needs to be installed through holes. It is very inconvenient and subsequently appeared. Elastic band headlights, but the above-mentioned wear-proof explosion-proof lights have major defects in terms of light efficiency, battery life and reliability.

3, flashlight side lights

There is a wearable explosion-proof illuminator called SME-8033, which consists of a light stand and a light. It can be placed on both sides of the fire helmet and can be rotated 360 degrees. The headlight can be adjusted for the pitch angle for easy fire protection. When the staff walks, they shine on the road ahead. The lamp holder can be removed from the helmet without any tools, so that the firefighter can reduce the weight of the helmet with or without the headlight according to the fire situation. The most advanced high-power LED bulbs in the world are used. It does not need to be replaced for life. The imported high-hardness alloy casing can withstand strong collision and impact, and has good sealing performance. It can reach the highest explosion-proof grade of explosion-proof type and can work safely in various inflammable and explosive places. . The author understands that the brand of lamps and lanterns is developed and produced by Shishi Electric, and has been widely promoted in China's firefighting forces.

Second, the main supplier of wearable explosion-proof lighting

1. Foreign brands

At present, the foreign companies that sell wearable explosion-proof lighting to China are mainly American Pelican Products Co., Ltd., and Pelican officially entered China in 2007. Its expensive price makes most fire-fighting units unbearable.

2, independent brand

Domestic independent manufacturers mainly include Yueqing Shishi Electric Co., Ltd., Shenzhen Ocean King Investment Development Co., Ltd., Huarong Group Co., Ltd., etc. The above three markets have a high market share and are the leaders in the development trend of domestic wear-proof explosion-proof lamps. In particular, Shimei Electric's SME-8033 and Shenzhen Ocean King IW5110 are the most representative.

Third, China's wearing explosion-proof lighting mainly has the following problems:

1. There are many manufacturers of explosion-proof lighting fixtures, small production batches and mixed models, which is difficult to form economies of scale.

2, wearing explosion-proof lighting manufacturers of their own defects. Most wear-resistant explosion-proof lighting manufacturers focus on market and light independent research and development; heavy sales investment, light technical transformation, designer's labor compensation is lower than the sales staff's labor compensation; focus on recent benefits, light technology and technological progress; re-establish public relations And tap the potential of talent resources within the company. Therefore, the company's backup technology and new product reserves are seriously insufficient.

3. There is no uniform industry standard for wearing explosion-proof lighting. China's wear-type explosion-proof lighting mainly comes from the manufacturer's product parameters, fire-fighting units can only passively accept the products given by the manufacturers, can not meet their own needs.

4. Product innovation ability is weak. There are few people in the technical design and process design of the enterprise, low education, low level and lack of experience. The professional technicians who are engaged in the design of new wear-type explosion-proof lighting lamps, especially the experienced research and design personnel with rich performance, have few talents who can complete the overall design independently, and even some enterprises have no design ability, no process documents, and production. “Photographing the gourd” has led to a long cycle of new product development.

5, the processing method is backward, the equipment is simple, and the consistency control of the parts quality is difficult. Some wear-type explosion-proof lighting enterprises, production workers with low technology, poor skills, usually lack of normal, healthy training channels, can only teach skills in the original simple way of Master with apprentice. Some enterprises have simple production equipment, and technical transformation measures are seriously lagging behind. There are no special production equipment and molds, but they are hand-pounded and patched together. Some production technical documents are not complete, quality supervision and management methods are not perfect, and the quality of produced parts is not guaranteed. So far, some wear-resistant explosion-proof lighting companies are still basically in the low-level stage of imitation, which has formed the embarrassing situation of “first-class enterprises imitating foreign products and second-rate enterprises imitating domestic counterparts”.

6, the demand is out of touch. Designers of wear-resistant explosion-proof lighting manufacturers are unfamiliar with major disaster disposal and fire-fighting and rescue technologies, while the personnel in the fire-fighting team do not understand the manufacturing process of wearing explosion-proof lighting, and there is a lack of communication platforms and channels. In addition, due to insufficient funds and backward management methods, the overall production progress of domestic wear-resistant explosion-proof lighting lamps is slow, and it is difficult to achieve independent innovation.

Fourth, wearing explosion-proof lighting prospects

The current world new light source and new energy lighting industry is in a stage of rapid development. With the continuous updating and progress of new light source and new energy lighting products, new light sources and new energy lighting will replace traditional light sources and traditional energy sources in the lighting industry. This will bring innovative opportunities and challenges to wear-proof explosion-proof lighting.

At present, most of the wear-proof explosion-proof lighting lamps have adopted high-power LED light sources. LEDs are solid-state cold light sources, which have the advantages of high electro-optical conversion efficiency, low heat generation, low power consumption, safe voltage and low voltage, and long service life. It is an ideal electric light source for wearing explosion-proof lighting. At the same time, the high price of LED products is a barrier to popularization. With the continuous development of LED light source technology, the production cost of wearable explosion-proof lighting will be reduced. The polymer lithium-ion battery has a significant improvement in capacity, charge and discharge characteristics, safety, operating temperature range, cycle life and environmental performance, and will provide a more durable and reliable power supply for wearing explosion-proof lamps.

In short, the wear-resistant explosion-proof lighting industry has developed rapidly, with great achievements and many problems, and the future will make a difference.
