01. What are the advantages and disadvantages of LED lights?
Advantages: New green and environmentally friendly light source: LED uses cold light source, with little glare, no radiation, and no harmful substances produced during use. LED has low working voltage, adopts DC drive mode, ultra-low power consumption (single tube 0.03~0.06W), electro-optical power conversion is close to 100%, and energy saving is more than 80% compared with traditional light sources under the same lighting effect. LED has better environmental benefits, there is no ultraviolet and infrared in the spectrum, and the waste is recyclable, there is no pollution, does not contain mercury, and can be safely touched. It is a typical green lighting source. Long life: LED is a solid cold light source, epoxy resin encapsulation, vibration resistance, and there is no loose part in the lamp body. There are no shortcomings such as easy burning of filament light, heat deposition, and light decay. The service life can reach 60,000~100,000 hours, which is more than 10 times the service life of traditional light sources. LED has stable performance and can work normally in an environment of -30~+50°C. Multiple transformations: LED light sources can use the principle of red, green and blue primary colors. Under the control of computer technology, the three colors can have 256 gray levels and can be mixed arbitrarily, which can produce 256X256X256 (i.e. 16777216) colors to form a combination of different light colors. The light color of LED combinations can be varied, and colorful dynamic change effects and various images can be achieved. Disadvantages: Heat dissipation problem. If the heat dissipation is not good, the life span will be greatly shortened. The power saving of low-end LED lamps is still lower than that of energy-saving lamps (cold cathode tubes, CCFL). The initial purchase cost is high. Because LED light sources are highly directional, the design of lamps needs to consider the special optical properties of LEDs.
02. What are the advantages of LED light sources for street lamps?
LED light sources have many advantages:1. Energy saving and environmental protection. Very low-power LED light sources can achieve the same lighting effect as high-power high-pressure sodium lamps;2. Long life. LED light sources basically convert electrical energy into light energy, with very little heat energy, so they have a long service life;3. High color rendering index. LED light sources are closer to sunlight, so the color rendering index is good and more realistic.
03. What are the structural characteristics of explosion-proof lamps?
1. Good explosion-proof performance, can easily be used in any dangerous places.2. Using LED as the source of light, it has high efficiency, wide irradiation range, and a service life of up to ten years.3. It has good electromagnetic compatibility to ensure that it will not affect the surrounding working environment. 4. The lamp body is made of a lightweight alloy material, which has the advantages of strong corrosion resistance and impact resistance; the transparent part is made of tempered glass made of high temperature resistance and impact resistance.5. It is small in size and easy to carry, suitable for use in various places, and the operation is simple and easy to understand.
04. What are the protection levels of the casing of explosion-proof lamps?
In order to prevent dust, solid foreign matter and water from entering the lamp cavity, touching or accumulating on live parts to cause sparks, short circuits or damage to electrical insulation, there are a variety of shell protection methods to protect electrical insulation. The characteristic letters "IP" followed by two numbers are used to characterize the shell protection level. The first number indicates the protection against people, solid foreign matter or dust. It is divided into levels 0-6. Explosion-proof lamps are sealed lamps with a dustproof capability of at least level 4. The second number indicates the protection against water, which is divided into levels 0-8.
05. Are LED industrial lighting harmful to eyes?
While providing efficient lighting, LED industrial lighting may also cause certain potential harm to the eyes, especially blue light, strobe and glare. By choosing the right products, installing and using them properly, these hazards can be effectively reduced and eye health can be protected. In practical applications, it is recommended to formulate a scientific lighting plan based on the specific working environment and needs to ensure the safety and comfort of LED lighting.
