The mark on the shell of explosion-proof lamps must be not less than 1mm thick
The signs on the shell of explosion-proof lamps must be made of bronze, brass, stainless steel with a thickness of not less than 1mm (the thickness of small lamps may not be less than 0.5mm), or other materials whose corrosion resistance is not lower than the aforementioned materials. It should also be securely fixed and not easily erased or dropped. The way to check the durability of the symbol is: rub it with a cloth soaked in water for 15 seconds and let it dry, and then use a cloth soaked in gasoline for 15 seconds. After visual inspection, the symbol should be clear and not fall off. The content of the nameplate mark should include: explosion-proof mark. Basic signs: including product name, type, manufacturer's name, registered trademark, date of manufacture, etc. Functional safety marks: including additional voltage, current, nominal frequency, power and quantity of light sources, allowable ambient temperature (the range is only -20 to +40°C, it may not be marked), specific applicable environmental marks (for example, only applicable to a certain The product of an explosive gas mixture must be marked with the name or molecular formula of the combustible gas), the classification mark of the lamp (such as "number"), etc. The number of the explosion-proof certificate proves that the product has been officially inspected by the explosion-proof inspection station. Some products have the explosion-proof certificate number. The "x" symbol after it indicates that the product can only be used under certain special installation and use conditions, and the specified conditions should be clearly and conspicuously indicated in the lamp housing or product manual.
The selection of explosion-proof lights is based on the season and the environment. The color temperature is selected: the color temperature is planned to be 2700~6500K. The smaller the value is, the yellow light is inclined, and vice versa, the blue and white light is inclined. Cozy and comfortable. The white light is brighter and clearer, which is suitable for summer, study, kitchen, etc.
It is necessary to focus on color contrast, and select high color rendering: Color rendering refers to the authenticity of the color of the object after being illuminated by light, and the value is 0~100. At present, the color rendering standard of LED bulb explosion-proof LED lights is greater than 75, but the expert advocates choosing more than 80 Preferably, people who have a studio at home should buy light bulbs with high color rendering, which can better reflect the authenticity of the color.
Select the quantity and luminous flux according to the number of squares and ambient lighting requirements: the luminous flux refers to the brightness. Under the same number of pings, the number of bulbs used is different according to different environments. For example, the bedroom and study room of the same 5 pings require 2 and 5 13-watt light bulbs respectively. Choose high luminous power: the higher the luminous power, the more power saving. The current luminous power of LED lights is generally higher than 80. The higher the value of explosion-proof lights, the more power saving. For the installation of explosion-proof lights, we should pay attention to the detailed construction methods, but also pay attention to choosing the explosion-proof lights that are suitable for us.
