Description
Technical Field
The invention relates to the technical field of explosion-proof illumination, in particular to an explosion-proof light source and an explosion-proof lamp.
Background
In the fields of petrochemical industry, ships and marine platforms, grain and oil processing and storage, metal processing and surface treatment, coal mines and the like, explosive gas or dust can be generated and accumulated in the environment, so that the lighting equipment used in the fields has to have explosion-proof performance, namely the explosion-proof lamp generally known by people. In general, lighting devices such as lighting fixtures and emergency lighting fixtures used in the above fields or environments must have explosion-proof performance.
The explosion-proof of the lighting equipment means that by one or more technical means such as structural design, circuit design, device selection or special process and the like, the lighting equipment can not ignite combustible gas or dust in the air when in normal operation or failure, and the explosion of the explosive dangerous environment can not be caused.
In recent years, with the development of industries and the continuous improvement of industrial standards, the market demand is more and more vigorous, and the products mainly comprise explosion-proof lighting products, explosion-proof mobile lighting products, explosion-proof fixed emergency lighting products and the like.
National and international explosion-proof industry standards such as GB3836 and IEC60079 not only make clear regulations on how an illuminating product meets explosion-proof requirements, but also indicate technical directions for practitioners. However, the explosion-proof form of the light source part of most of the LED explosion-proof lighting lamps in the current market still continues the scheme of the traditional light source explosion-proof lamp, and most of the LED light source parts adopt the explosion-proof technical means. However, the explosion-proof LED light source cavity has the following effects on the product in order to ensure that the explosion-proof surface meets the standard requirements and that the explosion-proof surface can pass the hydrostatic test (for proving that the explosion-proof LED light source cavity can bear the pressure generated by the explosion of the inner cavity, thereby ensuring that the explosion is not propagated outwards):
1. the degree of freedom of light distribution design is seriously influenced;
2. the thick and heavy shell greatly increases the cost of the material and the machining of the shell part;
3. the national and international industry standards strictly prohibit the position of the explosion-proof surface from being subjected to plastic spraying anticorrosion treatment. When the explosion-proof lamp is applied to ships, maritime workers, wharfs or other environments with high corrosivity, the non-plastic-sprayed position is often corroded firstly, and the slight corrosion can cause the loss of the explosion-proof performance.
In addition, almost all explosion-proof fire-fighting emergency lamps (emergency lighting and safety exits) in the current market are incompatible, and the product has serious structural limitation and excessively single function. Due to the structural and functional limitations, the lamp is not compatible with the common explosion-proof lighting lamp regardless of lighting performance or installation diversity.
Therefore, the invention provides an explosion-proof light source and an explosion-proof lamp, which can completely avoid all the defects.
