The traditional LED voltage is 3V, and the power supply is generally 3V~20mA, 30mA, 60mA. With the changes in people's lives, the requirements for lighting products are getting higher and higher, LED lighting products are getting brighter and brighter, and LED power has gradually become mainstream lighting products.
In the production of LED high-power products, the common practice of enterprises is to increase the size of LED chips and increase the current when the voltage is constant. However, the higher the current is, the more heat generated by the LEDs is increased. The damage to the LED product itself is also great. This is the reason why the quality of domestic high-power LED products is unstable in the past few years and often causes problems.
In the past, the world's leading LED companies are trying to solve this situation. Now there is a big technological breakthrough. If the current is constant, the voltage of a single chip is increased, so that the heat is reduced and the light efficiency is improved. The cost is reduced, and this product is called HV-high voltage LED.
HV-LED is the trend
In the production of high-power products, the common practice is to combine the single 3V chips in a string and relationship to obtain the required voltage and current, and connect them in series on the LED bracket or substrate, such as: 3x4. LED series or 3x5 LEDs are connected in series, resulting in a large amount of current. With the advent of HV-high voltage LEDs, this phenomenon has been greatly improved. In the case of constant current, the company increases the voltage of a single chip and turns many LEDs in series into A single chip solves the problem and the light efficiency of the product is also maximized.
And the damage to people is very small. The 5 million volt high-voltage Tesla coil laser dance performed on TV on the TV is an example. The extremely high voltage of the Tesla coil laser dance, the human contact with the high voltage is not hurt. The reason is that because the current is extremely small, the HV-LED is relatively less harmful to the human body's electric shock, and it can be said that the low current causes less damage to the LED chip.
Wei Weizhen, general manager of Xinchuang Technology Co., Ltd. said, "HV-high voltage LED is the development trend. At present, mainstream LED companies all over the world are developing in this direction, and the advantage of HV-LED is small voltage drop and high PF value (Power Factor). , low heat, high power efficiency, fewer parts and components, lower cost." Especially in the US market, PF value is the standard for measuring LED products.
Whether LED products are energy-saving is reflected in PF value and efficiency. For example, LED products with 100 points of power are effectively supplied to the chip with only 80 points, and the remaining 20 points are lost. The lost energy accumulates inside the product, causing heat to rise, neither saving energy. It is also a waste of electricity. Therefore, the standard of US government subsidies is that the PF value of LED products must reach 0.9 to receive subsidies.
The PF value of traditional LED lamps in the world is about 0.55 on average, while the PF value of HV-LED can reach 0.98, which is more efficient and more energy efficient.
In order to achieve high PF values, traditional LEDs need to be matched with better components, such as PFC originals, so the cost of the products is very high. If the quality of the products is guaranteed, the existing LED products have difficulty in significantly reducing the price. HV-LED is a principle to change the product, remove a lot of accessories, under the premise of ensuring product quality, the price can be greatly reduced.
At present, the HV-LED single chip sold in retail stores in the US market is at 50V, while the domestic technology HV-LED technology level is between 20-50V. Wei Weizhen said, "The HV-LED single chip of Xinchuang Technology has achieved 110V or 220V/chip, and can withstand high voltage and high current, and is at the leading level in the industry."
HV-LED bulb lamp revolutionary product
The traditional bulb lamp is composed of a chip plus a power supply and a heat-dissipating casing. If the quality is to be guaranteed, the sales price of the product in the terminal is very high. The lighting 5W bulb is sold at the Wal-Mart supermarket for 59 yuan, and the Sanxiong Aurora 4W bulb In B&Q, the price is 79.6 yuan, and the OSRAM 4.5W bulb is priced at 79.8 yuan in the Metro supermarket. LED bulbs are difficult to compete with energy-saving lamps at the terminal price.
Wei Weizhen said, "The introduction of HV-LED bulbs will greatly change the status quo, with the case study of 3W bulbs."
There are four methods for making voltage and current conversion in traditional 3W bulbs:
◠Voltage 3V ∽ current input 1A requires 1 LED chip. (High current)
◠Voltage 3V ∽ current input 300mA requires 3 LED chips.
◠Voltage 3V ∽ current input 30mA requires chip 5╳6=30.
◠Voltage 3V ∽ current input 60mA requires chip 5╳3=15.
If using HV-LED bulbs:
◠Voltage 50V ∽ power input 20mA requires 4 chips.
◠Voltage 220V ∽ power input 14mA requires 1 chip.
According to the traditional 3W bulb manufacturing method, the cost is high. The reason is that there are too many chips, and the cost of the power supply and the heat sink is 2-3 times that of the energy-saving lamps. If it is a method of making HV-LED bulbs, the cost will drop dramatically.
The advantage of HV-LED bulbs over conventional bulbs is that HVs only require chips and power supplies to form a bulb. With the technology of Xinchuang Technology, only one chip and power supply are needed to produce 4.5WHV-LED bulbs, which is extremely low cost.
Wei Weizhen said, "At the end of last year, it reached an agreement with Kabo Sitong Lighting to authorize Kabo Sitong Lighting to sell new technology to produce 4.5W HV-LED bulbs in China. The terminal retail price is 9.9 yuan. It will be in the national chain in April this year. Super, Carrefour supermarkets or Tesco supermarkets are starting to sell."
According to the calculation of 4.5W HV bulb = 40W incandescent lamp = 8W energy-saving lamps, and this product has a lifespan of 50,000 hours, longer than the life of energy-saving lamps.
Domestic Opus 7W energy-saving lamps sell for 17 yuan in Metro supermarkets, Philips 8W energy-saving lamps in supermarkets for 20.9 yuan, etc. Wei Weizhen said, "This product is not only eliminated from existing LED bulbs, but also in energy-saving lamps. Life."
The business opportunities in the HV-LED era are huge
HV-LED is characterized by a smaller product area, higher power and more stability, which can give product designers more design ideas and more versatility.
Wei Weizhen said, "Xinchuang Technology produces 3W HV-LED bulbs, which are only slightly larger than the middle finger. This product can be smaller. LED products will be gradually miniaturized in the HV-LED era. For example: G9 bulbs, he can completely replace the spotlights, can also be used on the lights, make the lights more compact, so that top car designers have more room for ideas."
“In the field of commercial lighting, the miniaturization of lamps and the increase in brightness will also bring huge commercial space. In the interior decoration, more space can be created for people to conceive the decoration design plan. The product itself is simplified by simplifying the power supply design. More stable and longer life."
At present, the luminous efficacy of LED is running from 100 lumens per watt to 150 lumens, and its 150 lumens LED efficacy is about 3 times that of CFL energy-saving lamps, thus achieving the level of comprehensive replacement of energy-saving lamps. HV-LED is accompanied by The important role, the business opportunities brought about is even greater.
