Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a multifunctional modular designed lamp used in high-risk environments. Background Art

[0002] As a special field of industrial lighting, LED explosion-proof lamps use solid-state cold light sources, which have the advantages of high electro-optical conversion efficiency, low heat generation, long service life, and environmental protection. They have now become the leading lighting products. LED explosion-proof lamps are suitable for dangerous places where flammable gases and dust exist. They can prevent the arc, sparks and high temperatures that may be generated inside the lamps from igniting flammable gases and dust in the surrounding environment, thereby meeting the technical requirements of explosion-proof. At present, with the rapid development of industries such as petroleum, chemical, coal mining, and food, LED explosion-proof lamps are increasingly used in production, warehousing, and transportation. The research and development and application of LED explosion-proof lamps have attracted the attention and attention of managers in various industries.

[0003] In dangerous or harsh industrial environments such as mines, refineries and petrochemical plants, due to the presence of gas, steam, dust or other corrosive substances in the surrounding environment, lamp components used in such environments are susceptible to corrosion, especially at the contact surfaces, joints and connections between various components. How to prevent these substances from entering the lamps becomes a challenge.

[0004] The heat effect generated by the work may also cause the LED lighting to dim over time, the high temperature may shorten or damage the LED driver life, and the reliability of the components of the LED lighting fixtures and possible premature failure. Therefore, traditional lamps need to be equipped with bulky heat sinks, which often complicate the lighting fixture components. At the same time, in order to make the lamp components operate safely and reliably in dangerous or harsh environments, traditional high-lumen LED lamp components are bulky, heavy, difficult to manufacture and expensive. The following problems need to be solved: 1. How to prevent the presence of gas, steam, dust or other corrosive substances in the surrounding environment from entering the lamp. 2. The luminous flux output of the light source is related to the temperature, and the temperature will also affect the life of the power supply. When working, the heat generated by the light source and the power supply placed in the same cavity will affect each other, and the heat dissipation is slow. 3. Some special occasions require emergency functions for lamps. The usual practice is to redesign a lamp with emergency functions, which is not compatible with ordinary explosion-proof lamps, increasing costs. Utility Model Content
