LED downlights are products developed on the basis of traditional downlights using new LED lighting sources. Compared with traditional downlights, LED downlights have the following advantages: energy saving, low carbon, long life, good color rendering and fast response. The design of the LED downlight is more beautiful and light. When it is installed, it can maintain the overall unity and perfection of the building decoration. It does not damage the setting of the lamp. The light source hides the interior of the building decoration. The light source is not exposed, no glare, and the visual effect of the person is soft and uniform.
In the era when LEDs are popular, more and more merchants are engaged in the manufacture and sale of LED downlights, and consumers who do not understand LED downlights have more doubts in the face of so many choices, so Jiuzheng Building Materials Network As a professional building materials furniture website, we analyze and test the performance advantages of LED downlights for consumers. It is convenient for consumers to purchase cost-effective products and to choose better LED downlight manufacturers.
Advantages of LED downlights:
1. Good color rendering: light from traditional lamps can be closer to white light, and the color of the object can be closer to its true color.
2. LED lighting technology is advancing with each passing day, its luminous efficiency is making amazing breakthroughs, and prices are constantly decreasing.
3. Environmentally friendly, free of substances harmful to the environment such as mercury (Hg), will not cause damage to the environment. The assembly parts of the LED Lamp can be easily disassembled and assembled, and can be recycled by others without recycling by the manufacturer. LED does not contain infrared or ultraviolet light, so it does not attract insects;
4. Energy saving: the energy consumption of white LEDs is only 1/10 of that of incandescent lamps and 2/5 of energy-saving lamps;
5. Longevity: LED theoretical life can exceed 100,000 hours, which can be described as "one time and for all" for ordinary household lighting;
6. Can work in high speed state: If the energy-saving lamp starts or turns off the filament frequently, it will be black and quickly damaged;
7. Fast response: LED response speed is fast, completely eliminating the shortcomings of the traditional high-pressure sodium lamp startup process.
8. Convenient transportation: solid-state packaging, which is a type of cold light source. Therefore, it is very convenient to transport and install. It can be installed in any miniature and closed equipment. It is not afraid of vibration. The main consideration is heat dissipation.
LED downlight performance advantages:
Whether the aluminum lamp casing is selected for the downlight casing, because the LED downlight most needs to solve the heat dissipation problem, and the aluminum alloy casing has good heat dissipation performance, so the service life and the luminous effect of the LED downlight can be prolonged, and the aluminum alloy casing is further extended. It can be recycled and used in response to environmental protection advocated by the state. Careful inspection of the chip, the chip is the most critical accessory for LED, which affects the overall effect of the LED. For the inspection of the brightness of the product, our requirement is that the color of the light is stable and durable, and there is no flash frequency. Check the power of the LED downlight, the drive power can affect the life of the led, so we need to choose DC power, and AC power will easily shorten the life of the led.
To choose a good LED downlight, you can pay more attention to it from the performance advantages. Therefore, consumers should start from the details when buying, and observe and try it to see if its performance has an advantage. More conducive to buying a good product.
For energy-saving, environmentally friendly, low-pollution LED downlights, I believe that many consumers are pursuing products that are worth recommending to everyone.
A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe. A blind flange is a plate for covering or closing the end of a pipe. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.
Although the word flange generally refers to the actual raised rim or lip of a fitting, many flanged plumbing fittings are themselves known as 'flanges':
There are many different flange standards to be found worldwide. To allow easy functionality and interchangeability, these are designed to have standardised dimensions. Common world standards include ASA/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). In the USA, ANSI stopped publishing B16.5 in 1996, and the standard is ASME B16.5
