How to produce LED Neon Flex Lights?

The production process is divided into two main parts.

In the first part, the LED flexible strip is produced first, and the LED flexible strip is used as the light source for the neon lights. Please read "How To Produce LED Strip Lights?" if you need to know how to produce led strips in detail.

The second part is to add the silicone shell to the LED strip. There are two main ways to add the silicone shell. The first way is LED strip and silicone integrated extrusion. The second way is to produce the silicone tube first and then put the LED strip into the silicone tube manually.

 

LED strip and silicone integrated extrusion process

Step 1. Mixing silicone

Step 2. The extrusion process begins with installing rolling LED strips on the payoff frame. These LED strips are adjusted and sequenced using an adjustment table.

Step 3. The LED strip and silicone are then passed through the holes in the pre-assembled die, activating the operating button on the electronic control box, which starts the machine to wrap the silicone onto the LED strip.

Step 4. The machine extrudes the silicone-coated LED strip and passes it through the vulcanizing oven, where the product is gradually vulcanized and shaped. The temperature inside the oven is kept moderate to avoid burning the LED beads. After vulcanization, the led neon is put out by a tractor.

Q: 7.How long does LED Neon Flex last?

A: Generally, the lifetime of LED neon is between 30,000 hours and 5,000 hours, which ultimately depends on the quality of the light source LED and the heat dissipation effect of the LED neon tube.

Q: 8.Is LED Neon Flex more environmentally friendly?

A: Yes. LED neon lights do not contain harmful chemicals such as heavy metals, use less electricity, are not easy to break, have low operating voltage, are safe, and have a longer lifespan.

Q: 9.What is Traditional Neon Lights?

A: Traditional Neon lights are brightly emitting electrified glass tubes or bulbs filled with rare neon gas or other rare gases and are a type of cold cathode gas discharge lamp. A neon tube is a sealed glass tube with electrodes at both ends, filled with low-pressure gas. A voltage of several thousand volts is applied to the electrodes, ionizing the gas in the tube, causing it to emit light. The color of the light depends on the gas in the tube. Neon is a transliteration of neon light, a rare gas that emits a popular orange-red light. But other colors are produced using other gases, such as hydrogen (red), helium (pink), carbon dioxide (white), mercury vapor (blue), etc.

Q: 10.What are the features of LED Neon Flex lights?

A: 1. The working voltage is low because of the LED light source. The power consumption is small and energy-saving. Even in the 24Vdc, it can work well, and its power consumption generally does not exceed 15W per meter.
2. High brightness. The light source is made of ultra-high brightness SMD LEDs, with a density of 120 LEDs per meter, ensuring high brightness and an overall uniform luminous effect.
3. Durable and long life. The light source is made of LEDs, which can last up to 50,000 hours. The flexible silicone/PVC/PU gel is also used, so there is no problem breaking like traditional glass neon light.
4. Flexible, the LED neon flex light can be bent to a minimum diameter of 5CM and sheared.
5. Safe. Unlike traditional glass neon lights, which require a high voltage of up to 15,000V for regular operation, the LED neon flex light operates at 12V or 24V and is safe to use as it will not break and has low heat dissipation.
6. Simple and easy to transport and install. Because the light source is LED and the casing is PVC/Silicone/PU, it will not break during transportation. You only need to fix the mounting clips first or mounting channels, then press the LED flexible neon into mounting clips or mounting channels.

Q: 11.What is the advantages of LED Neon Flex Lights compare with Traditional Neon Lights?

A: 1. Traditional neon lights are expensive, complex, and inconvenient when using glass tubes, high voltage electricity, and inert gas. LED neon flex lights using LED technology and a new structure, with a PVC, silicone, or PU housing wrapped around the LED light source, using unique optical design technology and a special housing design to increase the intensity and uniformity of the light. The LED neon flex is easy to manufacture and very efficient.
2. LED neon flex lights are brighter than traditional neon lights.
3. LED neon flex lights have a longer life span and are more durable. With LED as the light source and PVC/Silicone/PU housing, the life span of LED neon flex is up to 30,000 hours.
4. LED neon flex lights are more energy-efficient, with a minimum power of less than 5W per meter than traditional glass neon lights, generally more than 20W per meter.
5. Traditional neon lights use a transformer to raise the voltage from 220V/100V to 15000V to excite the inert gas in the glass tube. One set of glass tube can only emit one color of light. If multiple colors are required, multiple sets of glass tubes are needed. And the traditional neon shape needs to be designed in advance, and the shape cannot be changed after the factory has produced it. LED neon flex lights can be bent and cut at the site, and there are many different colors to choose from white, tunable white, RGB, RGBW, DMX512 Pixel, etc.
6. LED neon flex lights is safer, as it uses low voltages: 12V, 24V, shockproof, low heat dissipation, and safe to use.
7. Conventional neon lights can only work at normal room temperature, and the voltage must be raised during use, which is also more expensive and has a short service life. The LED neon flex light uses LED as the light source, a cold light source with low heat dissipation and low power consumption. It is also shockproof and heat resistant.
8. LED neon flex lights are more friendly to the environment. While traditional neon lights are polluted with heavy metals, LED neon flex lights do not contain heavy metals or other harmful substances.
