ultraviolet led bulbs application
With the widespread use of LED’s and performance improvements, a new lighting revolution is about to sweep the world, people look forward to the overall lighting of the LED scene (ultraviolet led bulbs) change will bring advantages to the people, which is also worthy of our attention.
LED Street Light is more convenient in terms of brightness, color temperature, color controllable adjustable. Lighting development of human society can be divided into three stages. The new stage is the LED street light for lighting like (ultraviolet led bulbs), lighting on the new stage. The tricolor LED allows any visible color can be changed at any time. And in the brightness, color temperature regulation and more convenient.
LED stressed that the overall effect of the change in the past a single lighting
Lighting in everyday life are usually single or partial lighting, but it does not reflect the overall effect. LED small size, can be installed in the building materials, decorative materials and work in the Fine Arts in goods. The semiconductor light-emitting diode bulbs material, so very small, this light-emitting device can do, to achieve nanometer order of magnitude, while the long life of LED lights, more energy efficient.

problems of using led grow lights
Currently, more and more lighting products use LED, such as LED lamps, LED Lawn Light, LED spotlights, LED underwater lights, the LED ground lights and so on. While everyone has a better understanding of energy-saving LED light source, long life, no radiation (green light), etc., but several key issues related to LED products (using led grow lights) also need to pay attention:
1, DC constant current power supply
LED products dedicated switching power supply (constant current source)-powered LED products will not affect the life of the product, but the product cost is relatively high.
LED products dedicated switching power supply (constant current source)-powered LED products will not affect the life of the product, but the product cost is relatively high.
2, to make anti-static measures
Different level of quality LED products, antistatic aspects are not the same, so the LED products to be used in the production process in the processing of certain anti-static measures: workbench ground, wear anti-static clothing, with anti-static ring with anti-static gloves, a conditional can be installed on anti-static ion fans, but also to ensure that the humidity around 65%, so that the air is too dry to produce static electricity, especially the green LED, it is relatively easier to be damaged by static electricity.
3, temperature cause the LED internal resistance smaller
When the outside ambient temperature, the LED light (using led grow lights) source resistance will reduce the choice of the constant current source to ensure that the LED current is independent of outside temperature.

4, Sealing of LED products
Used in the outdoor LED products are facing a waterproof, moisture-proof seal, if not handled properly it will directly affect the service life of LED products. Traditional epoxy “watering” way to seal the LED products, this approach is too much trouble, would cause an increase in the weight of the product.

The quality of the LED products currently on the market and the poor, good quality LED light source with high brightness, the light fades, the antistatic ability, long life, but cheaper than the price of a few times. Although some LED lighting project using low-quality low-cost LED light source will not find any problems, but will soon be “incomplete arrhythmia, manufacturers and users not on price” flame “. Selection of affordable, good quality LED light (using led grow lights) source, to ensure the life of the lighting project.
uv led grow light in led sorting
The initial LED is mainly used to sort the lights, and generally a single device, so the wavelength separation and brightness control does not require a high. LED normally in accordance with the dominant wavelength, luminous intensity, luminous flux, color temperature, operating voltage, reverse breakdown voltage of several key arguments for testing and sorting. LED Lights testing and sorting is a necessary process in the LED production (uv led grow light) process, but also an important part of the LED chip production and packaging costs.LED sorting in two ways: First, the chip-based separation, the second is the separation of packaged LED.
Chip test sorting in two ways: One way is to test the sorting done by the same machine, its advantages are reliable, but is very slow, low capacity; Another method is to test and sorting by the two machine to complete, test equipment records the location of each chip and argument, then passed to a sorting device for quick sorting, the advantages of doing so is fast, but the drawback is that the reliability is lower than the right, error-prone because usually there are two steps between the testing and sorting substrate thinning and chip separation process, in this process, epitaxial wafers may be fragmentation, partial incomplete fragmentation or partial incomplete, making the actual chip decentralized and does not match the information stored in the sorter, resulting in the separation difficult. The chip testing a fundamental solution to the bottleneck problem of sorting is to improve the uniformity of the wafer.LEDs can be packaged in accordance with the wavelength, luminous intensity, light-emitting angle and voltage of the test separator. The increasingly high demand for LED Street Lightearly sorter is 32Bin, later increased to 64Bin now the 72Bin commercial sorting machine. Even so, these LED technology (uv led grow light) indicators are still unable to meet production and market demand.The large display screen or other high-end applications users require a higher quality of the LED. In particular, is very strict requirements of the wavelength and brightness consistency. LED packaging factory foruv led grow light in the chip procurement stringent requirements, these packaging plants in a large number of package will find packaged LED only a small number of products to meet the requirements of a particular user, most of the rest will become the stock in the warehouse. This situation forced the stringent requirements in the procurement of the LED chip, LED high bay packaging factory is characterized by wavelength, brightness, and table-voltage indicator.

The LED torch is a new lighting tool with light-emitting diodes as light sources, it has low power consumption, durability, brightness, etc.. With the improvement of the white LED brightness, reduced costs, and gradually go such as the mass ranks. Currently, the U.S. and European markets have been large volume applications in high-power LED torch and video led light panel. For example, a dedicated to the field of high power LED flashlight: Challenger – Polar Light of Hight Power LED flashlight and LED High Bay using the original authentic high brightness 1W the LED (brightness up to 40 to 50 lumens) using constant current circuit design, the LED real done energy saving, low power consumption, long service life of 100,000 hours, a battery of six to eight hours, the shell is made of aluminum-magnesium alloy, anodized, corrosion resistant, super anti-vibration capability, coupled with waterproof structural design, able to adapt to the wild variety of harsh environments. The lamp condenser design, the irradiation distance of up to 50 ~ 100 meters, but also manual dimming, to achieve the best condenser effect of video led light panel.

voltage for led lights in led production
In the LED street light production, when we produce the chip package, the cup bubble occupies a large proportion, but the product in the production process if the bubble problem has not been a good solution or prevention, it will cause decay products a factor to accelerate the performance of IV to reduce the IR VF increased. So, any solutions for the existence of bubbles and plastic mixing full? Here we analyze from the few comments given by the people in the voltage for led lights industry.
Factors affecting bubbles, but do some engineering assessments, can be solved led high bay step by step. If there is a bubble cup, you can give a certain percentage of the plastic cup filling, and then proceeding to the next step process. The following relevant factors:
1. An environmental temperature and humidity had a greater influence on the bubble.
2. mold temperature is also generated a factor of the bubbles.
3. the formation of air bubbles and process adjustment.

1. An environmental temperature and humidity had a greater influence on the bubble.
2. mold temperature is also generated a factor of the bubbles.
3. the formation of air bubbles and process adjustment.
For example, some factories there is no vacuum, no air bubbles, and even if the factories pumping vacuum bubbles, it should not be pumping vacuum. But the operating speed of skilled into a question of degree. And ambient temperature are also inseparable. Ambient temperature changes, we can take appropriate measures to control. If room temperature is 15 degrees, we must find ways to help glue the temperature reaches 60 degrees, so do the bubble cup should not occur again! Meanwhile, we should pay attention to many details in voltage for led lights. Such as tiny bubbles by eyes and subtle microscope can not see the drum pre-stick adhesive, but into the oven body, hot flatulence bubble expansion up.
Manually pre-Glue, brackets must be preheated. Preheat the pre-filling the AB material to swap the first two hours. As long as you keep the AB material, stents are hot bubble problem is not intractable. Encountered because of poor mobility, AB Cold, Cold bracket easily into the bubble. The operation should pay attention to the following question about voltage for led lights:
1. operating skills of the operator (the whole there are side air bubbles)
2. stick gum machine speed and the gel content is not well controlled (very prone to bubble place)
3. Machine is clean (this point will not cause air bubbles, but it is prone to the same thing similar to the ice, especially cyclohexanone)
4, To bracket the viscose, the drum speed is not fast.
5. change Glue, clean the rollers and led lights.
6. viscose machine.
