As we all know, more than thirty years ago, ultraviolet-UV light was successfully promoted to commercial applications. Various adhesive manufacturers have developed a series of UV products for bonding, sealing, printing, etc. according to UV light curing characteristics, and they are widely used in many fields such as communications, electronics, optics, and printing. These products will be cured or hardened and polymerized under the irradiation of a certain wavelength of UV light and a certain light intensity, and the UV light curing of traditional products is more efficient, energy-saving, and environmentally friendly. Let’s talk about the related knowledge of UV led light bar for the greenhouse today.
What is the difference between UV led light sources and traditional UV light?
What are the advantages of the UV led light bar for the greenhouse?
The UV led light source is a single wavelength, and the traditional UV lamp is a wide range of 200-400nm. Because the traditional UV lamp is a wide band, and only one of the wavelengths is used, the other light waves are useless and wasted. Different occasions need to make a single wavelength.
UV led light source has the advantages of high efficiency, energy saving, environmental protection, low temperature, long life, etc.
1. Service life
Compared with traditional UV curing equipment, the life of a traditional UV lamp is about 1000 hours, and the life of its mercury lamp is only 800-3000 hours, and the service life of a UV led ultraviolet curing system reaches 20,000-30000 hours. The LED method can be lit instantaneously only when ultraviolet light is needed. According to the DUIY one-fifth preparation time = 5 irradiation time 1, the service life of the LED method is equivalent to 30-40 times that of the mercury lamp method. Reduce the time to replace the bulb: improve production efficiency, but also very energy-saving. When the traditional mercury lamp curing equipment is working, because the mercury lamp starts slowly and the opening and closing affects the bulb life, it must be lit all the time, which not only causes unnecessary power consumption but also shortens the working life of the mercury lamp.
2. Without heat radiation
High-power LEDs do not emit infrared rays. The surface temperature of the irradiated product rises below 5 degrees Celsius, while the traditional mercury lamp method of ultraviolet curing machine generally raises the surface of the irradiated product by 60 to 90 degrees Celsius, which causes the positioning of the product to shift, resulting in product failure. The UV led light bar for the greenhouse is suitable for thermally sensitive and high-precision bonding process requirements such as plastic substrates, lens bonding, electronic products, and optical fiber cables.
3. Environmental protection and no pollution
The traditional mercury lamp curing machine adopts the mercury lamp lighting method. There is mercury in the bulb, which is very troublesome for waste disposal and transportation, and the short wave emitted will cause the oxygen in the air to react to produce ozone, which is harmful to the human body. It needs to be equipped with exhaust air. The system, improper handling will cause serious pollution to the environment. The LED curing machine uses semiconductors to emit light, and there is no pollution to the environment. Therefore, the use of UV led light bar for the greenhouse is more environmentally friendly.
It is the responsibility of each manufacturer to produce a UV led light bar for a greenhouse that meets the standards, to ensure the healthy development of the market. BLE Shenzhen semiconductor lighting Co., Ltd. conducts many tests on the UV led light bar for the greenhouse before they leave the factory, and the quality qualification rate is guaranteed. If you are in the UV led light bar for the greenhouse business, you can consider our cost-effective products.
