The lamp beads used in general plant lighting are
The lamp beads used in general plant lighting are:
0.2W-0.5W: 2835 lamp beads, 5730 lamp beads, 5050 monochromatic lamp beads, 5050RGB full-color lamp beads;
1W-3W: PCT/EMC2835 lamp beads, 3030 lamp beads (can replace high power imitation lumen structure)
Unique 5W plant lighting lamp beads: S8 mixed light beads, 5252 lamp beads, 5059 lamp beads
Unique 12W plant lighting beads: 7070 mixed light beads.
Plant growth lights mainly use 640NM red light beads, 740NM high red light beads, 450-470nm blue light beads, and 365-410nm purple light beads.
Full Spectrum Grow Lights:
Contains a wavelength of 400-420nm, which helps to form anthocyanins and resist the elongation of branches and leaves.
Purple light is the central area of plant phototaxis, which can affect the morphogenesis of plants
Purple light inhibits plant trunk and page growth
With a wavelength of 450-460nm, it can thicken stems and leaves, accelerate plant development, and regulate the opening of stomata.
Blue light has a great effect on the early stage of plant growth, helping plants to establish a well-developed root system
The growth of the trunk and the page has been increasing the thickness of the trunk
Chlorophyll a/b has a strong absorption rate in the blue light area, which mainly helps plants synthesize proteins. In low-light environments, blue light does not have as much photosynthesis as red light for plants. Properly increasing blue light can make it more uniform and healthier, prompting plant quality
The wavelength is 550nm, which promotes the growth of oxygen and helps tissues to better store nutrients
The wavelength is 580nm, which can promote the growth of roots and early germination.
The wavelength is 650-660nm, which promotes the overall growth of plants, especially in the flowering and fruiting stages, increases the growth rate (flowering 20 days earlier, harvesting 30 days earlier), also increases the number of fruits by 25% to 35%, and reduces the incidence of deformed fruit.
720 ~ 1000nm has a low absorption rate, which stimulates cell elongation and affects flowering and seed germination.
In addition, the visible light of this product is a kind of electromagnetic wave, and also contains a small amount of ultraviolet rays, which can effectively prevent pests and diseases.
There are many welding methods for LED lamp beads on the chip, and the following is one of the commonly used methods for reference. First, use an electric soldering iron to heat some soldering tin on the positive and negative electrode pads of the lamp bead (the soldering tin must not be too much, otherwise, the positive and negative electrode pads will be connected once heated with a hot-air gun), then use a hot-air gun to heat the positive and negative electrode pads at the same time, after the tin melts, use tweezers to place the positive and negative electrodes of the lamp bead on the corresponding pad.
LED is the light emitting diode, which is a semiconductor solid light emitting device that converts electric energy into light energy. Its core is the PN junction. In addition to the forward conduction, reverse cut-off and breakdown characteristics of the general PN junction, it also has the light emitting characteristics under certain conditions. Its structure mainly includes the following parts: lead, bracket, encapsulation glue, bonding wire, LED chip, solid crystal glue and phosphor. The discoloration failure of LED lamp bead is closely related to its material, structure, packaging process and service conditions. The following will analyze the causes of its discoloration through specific cases.
LED lamp beads are also called light emitting diodes. It has a wide range of applications. Its luminous colors include red light, emerald green light, yellow green light, yellow light, purple light, blue light, white light and orange light. The above is monochromatic light. It can also be made into two or three colors.
The gold wire used to package LED lamp beads contains more than 99.99% gold. It is produced by drawing gold from this material. In addition to 99.99% gold, this gold also contains less than 1% other trace elements. One of the core components of LED lamp bead packaging is gold wire, which is the bridge connecting the luminous chip and the welding point, and plays a decisive role in the service life of LED lamp bead. So how to identify the purity of gold thread?
