What to pay attention to when choosing quality led torch light
Quality led torch light is used more and more by the people. It was used more for production 12 years ago. As the price of the LED market dropped, the price of the previously high products also dropped a lot, and slowly some citizens began to use quality. led torch light. Small size, convenience, energy saving, and high brightness are important reasons why quality led torch light is popular among consumers. If the market is large, manufacturers will increase a lot. Many small factories also need to process and produce LED flashlights. If the quality of the products cannot be fully guaranteed, how can we choose a durable strong light flashlight?
There is a big gap between the functions and prices of quality led torch light products on the market. How to choose the product that suits you?
The type and intensity of quality led torch light are what consumers care about, and it is also an important factor affecting the price. To understand the intensity of a light source, you must first know the unit of light: Lumens, which represents the amount of radiant light energy per unit time, or the total amount of light emitted. The larger the number of lumens, the more light emitted, and of course the brighter it is. HID (High Intensity Discharge) gas discharge bulb, also known as xenon lamp, has high luminous efficiency (1W luminous about 50 lumens); it was first used in sports field lighting. In recent years, quality led torch light has also used it to replace traditional Halogen lamp. Due to the characteristics of high illuminance (more than three times that of halogen lamps) and low power consumption (about half of the general halogen bulbs), the life span is 2.000~3.000 hours. Recently, it has been gradually transplanted to bicycle lights for use; HID can be used It is said to be the brightest option for bicycle lights, but it is expensive, mainly for professional athletes and mountain adventure enthusiasts who need strong lighting.
Light Emitting Diode is an electronic component that can convert electrical energy into light energy. It also has the characteristics of a diode, that is, it has a positive electrode and a negative electrode. The LED will only emit light when it is energized from the positive electrode. Therefore, the LED will be given a branch current. It will emit light steadily, and if it is connected to AC power, the LED will flicker. At the beginning, it was mostly used on indicator lights and display panels. With the appearance of white light emitting diodes, it was also used as lighting. In addition to its high efficiency (approximately 60 lumens of 1W light), long life (approximately 50,000 to 100,000 hours), not easy to break, low temperature during lighting, and moderate price, the important thing is that it also saves energy and is environmentally friendly without mercury. The advantages, so it is called the new light source of the century.
