LED industrial light buying guide
The emergence of LED lamps has greatly reduced the power required for lighting. LED lamps of the same wattage require only 1/10 of that of incandescent bulbs. At the same time, LEDs have the advantages of long life, environmental protection, and maintenance-free, which quickly replace incandescent lamps. Location. Before this, people have been using the incandescent light bulb invented by Edison in the last century, and the incandescent light bulb wasted most of the energy on heating, and about 90% of the electricity was wasted. With the mature development of LED technology, the scope of application has become wider and wider, which has changed the entire industrial industry and the entire world.
At present, the LED lights on the market are dazzling because of their diverse varieties and complete functions. So how can we choose suitable lamps? There are mainly two choices: structural and functional choices.
Structure can be understood as the design of the product itself, which can be judged by the following parameters.
IP (INGRESS PROTECTION) protection grade system is drafted by IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION), which classifies electrical appliances according to their dust and moisture resistance characteristics. The IP protection level is composed of two numbers. The first number "I" represents the level of protection against dust and foreign objects in the electrical appliance. Live parts to avoid electric shock), the highest level is 6; the second number "P" indicates the degree of airtightness of the electrical appliance against moisture and water immersion. The larger the number, the higher the protection level, and the highest level is 8. The luminaires can be IP64-IP65, which are already fully qualified for outdoor lighting, and are not afraid of them in humid and harsh environments.
The IK standard is applicable to the protection classification of electrical equipment enclosures with rated voltage not exceeding 72.5 kV against external mechanical collisions, and is only applicable to enclosures that have special requirements for external mechanical collision protection classification. Code letters (international mechanical protection-international mechanical protection) Characteristic combination of numbers (00 to 10), grades are divided into IK01-IK10, the higher the grade, the more anti-drop.
ETL is the abbreviation for Electrical Testing Laboratories. As long as any electrical, mechanical or electromechanical product carries the ETL mark, it indicates that the product has reached the minimum requirements of the generally recognized product safety standards of the United States and Canada, and it has passed the test to meet the relevant product safety standards. ETL also requires that its production site has been inspected, and the applicant agrees to conduct regular follow-up inspections to its factory thereafter to ensure that the product always meets this requirement.
Functional choices are mainly color temperature, wattage, and luminous efficiency.
The color temperature is the unit of measurement to identify the color of the light, expressed by the K value. The smaller the K value, the color will be warmer to yellow. The higher the K value, the whiter the light color. Generally, industrial lighting takes into account industrial lighting to keep the entire ground area and working surface bright, with a wide range of illumination, uniform illumination, soft fiber, and no glare. Generally, 5000K is most suitable.
Wattage (W) is the unit of measurement for power. Therefore, Watt refers to the power of the device. Example: The power of an LED lamp is 30W, and the power of an incandescent lamp is 60W.
Q: So, the higher the wattage of the lamp, is it brighter?
A: Yes, the larger the lamp wattage, the brighter it is. The wattage of the bulb should be called the rated power according to the standard. In the same kind of bulb (such as LED), the higher rated power will do more work under normal conditions, the more significant the effect of doing work (luminescence) will be.
Q: When we choose lamps and lanterns, the higher the wattage, the better?
A: No, there are two reasons. The higher the wattage, the higher the power consumption. The efficiency of LED energy-saving lamps is much higher than that of incandescent lamps. 6W LED lamps may be brighter than 25W incandescent lamps. The energy consumption of white LED is only 1/10 of that of incandescent lamps and 1/4 of that of energy-saving lamps. There is no doubt that LED lamps should be chosen.
Luminous efficiency is the ratio of luminous flux to electric power, and the unit is generally lm/W. Luminous efficiency represents the energy-saving characteristics of the light source, which is an important indicator to measure the performance of modern light sources. The unit of luminous flux is lumens, which can be simply understood as the light visible to the naked eye. The higher the luminous efficiency value, the more wort.
