What is the difference between low-voltage light bulbs and high-pre ssure light bulbs
Low-voltage light bulbs have the characteristics of safety, explosion-proof, energy saving, etc., and are widely used in mobile equipment lighting, household Electrical auxiliary lighting, industrial and mining and other special occasion lighting and other fields.
High-voltage lamp: a compact alternative lamp suitable for power supply voltage and attracting much attention
1. From a safety perspective: the high-voltage LED lamp strip uses a voltage of 220V, which is a dangerous voltage and can be used in some risky situations. Potential safety hazards; low-voltage LED light strips operate at a DC 12V working voltage, which is a safe voltage and can be used in various situations without any danger to the human body.
2. From the installation point of view, the installation of high-voltage LED light strips is relatively simple. It can be driven directly by a high-voltage driver. Generally, it can be configured directly in the factory and it can work normally when connected to the 220V power supply. The installation of low-voltage LED flexible light strips requires a DC power supply in front of the light strips, which is relatively complicated to install.
What are the advantages and disadvantages of low-voltage lamps
Advantages of low-voltage lamps
1. Safety: Low-voltage lamps are generally 12V/24/36V, which are voltages that the human body can safely withstand. They can be used in places required by national standards. Or a place with a higher safety factor.
2. Longer life: Because the circuit is DC low voltage, it uses fewer components and has a longer life.
3. No flicker. Since it uses DC voltage, it avoids stroboscopic phenomenon during AC use.
4. Small size: Because there is no need for complex circuits, the size can be as small as possible.
Disadvantages of low-voltage lamps
It needs to be connected to low voltage and is not compatible with the commonly used 220V.
What are the advantages and disadvantages of high-pre ssure lamps
Advantages of high-pre ssure lamps
1. Easy to use: It can directly replace the existing 220V circuit lamps, without the need for circuit conversion or wiring changes.
2. Strong versatility: good match with accessories on the current market.
Disadvantages of high-voltage lamps
1. High voltage is dangerous.
2. The size is not easy to be miniaturized.
Applicable places for low-voltage light bulbs
The standard lighting voltage is AC 220V. Depending on the needs of special projects, AC 127V or DC 36V may be used, or other lamps with lower voltage levels than standard lighting, called low-voltage lamps.
Low-voltage lamps have the characteristics of safety, explosion-proof, and energy saving, and are widely used in mobile equipment lighting, household appliance auxiliary lighting, industrial and mining and other special occasion lighting and other fields.
Applicable occasions for low-voltage crystal lamps - leisure places
LED light effect, one of the functions of low-voltage crystal lamps, is exactly what leisure places need. Made entirely of crystal, the texture is transparent and has no metallic texture, giving people a warm and natural feeling. Made entirely of crystal, it is also the need for overall aesthetics. Enjoy the beauty brought by the crystal lamp and enjoy the moment of tranquility in leisure places in busy life.
Applicable occasions for low-voltage crystal lamps - clothing and accessories chain stores
It is reported that the sales of low-voltage crystal lighting fixtures have increased by 30% compared with the first half of 2012, which mainly depends on the diversification of accessories for low-voltage crystal lamps selection. It can be an electroplated glass shot glass, it can be a tassel, it can be worn with beautiful earrings, etc.
The main differences between high-voltage light strips and low-voltage light strips are in safety, installation, price, packaging and service life:
1. Safety: high voltage LED light strips operate at a voltage of 220V, which is a dangerous voltage and may pose safety hazards when used in some risky situations. Low-voltage LED light strips operate at a DC 12V operating voltage, which is a safe voltage and can be used in various situations. It is harmful to the human body. There is no danger;
2. Installation: The installation of high-voltage LED light strips is relatively simple. It can be driven directly by a high-voltage driver. Generally, it can be configured directly in the factory and connected to the 220V power supply. It works fine. The installation of low-voltage LED flexible light strips requires a DC power supply in front of the light strips, which is relatively complicated during installation;
3. Price: If you choose only two light strips It seems that the prices of LED light strips are about the same, but the overall cost is different, because the high-voltage LED light strips are equipped with high-voltage power supplies. Generally, one power supply can carry 30 to 50 meters of LED flexible light strips, and, relatively speaking, It is said that the cost of high voltage is relatively low.
Low-voltage LED light strips require an external DC power supply. Generally, the power of a 1-meter 60-bead 5050 light strip is approximately 12~14W, which means that each meter of light strip must be equipped with a DC power supply of about 15W. , so the cost of low-voltage LED light strips will increase a lot, which is much higher than high-voltage LED light strips. Therefore, from the overall cost point of view, the price of low-voltage LED lights is higher than that of high-voltage LED lights;
4. Packaging: packaging of high-voltage LED light strips and low-voltage LED Light strips also vary greatly. High-voltage LED flexible light strips can generally be 50 to 100 meters per roll; low-voltage LED light strips can generally be up to 5 to 10 meters per roll; DC power supply attenuation beyond 10 meters will be severe. ;
5. Service life: The service life of low-voltage LED light strips will technically be 50,000-100,000 hours, but in actual use it can also reach 30,000-50,000 hours. Because of the high voltage, high-voltage LED light strips generate much more heat per unit length than low-voltage LED light strips, which directly affects the life of high-voltage LED light strips. Generally speaking, the service life of high-voltage LED light strips is about 10,000 hours;
