stealth grow led light and Humane and artistic

The inherent characteristics of the LED lights is the ideal light source to replace the traditional light source, LED is basically a tiny chip encapsulated in epoxy, so it is very small, very light. Low power consumption, under the appropriate current and voltage, LED service life of up to 100,000 hours. The LED is non-toxic materials, unlike fluorescent lamps containing mercury pollution caused by the LED can also be recycled. Since the LED is completely encapsulated in epoxy resin inside than light bulbs and fluorescent tubes are sturdy. Light body and no loose parts, these features make the LED can be said that is not easily damaged. LED as a new type of lighting technology and its application prospect is remarkable, especially in high-brightness LED known as the most valuable source of the 21st century, will cause a new revolution of lighting in the area.

1, user-friendly

Needless to say, the light of human relations is an eternal topic of the highest state of the lamps is the highest manifestation of the "shadowless" user-friendly lighting, no traces of any common lamp in the room, so that people can feel the light but can not find the light , embodies the perfect combination of light and of human life, humane design.

LED lighting product light, the choice of different light-colored LED into the soft illumination of the various modules, and any installed in the living room, bedroom lighting, the light source may be from the floor, wall, window sills, furniture, accessories and other. Therefore, the next room lighting will no longer be limited to a single lamp, but will be a single lighting into the shadowless lighting apparatus of the overall lighting effect. The different colors of light and brightness to produce different effects on human physiological and psychological can, in many cases do not need a very bright white light may be yellow or other colors of light more suitable for physiological and psychological needs. Three color LED tubes brightness, grayscale and color continuous transformation and selection, making the lighting extended to a variety of colors of light from the white light on the universal significance.

Therefore, it can be based on the overall lighting needs (such as color, temperature, brightness and direction, etc.) to set the lighting effects to achieve the control of human wisdom, and create a different interior lighting effect.

2, art

The light color is to constitute the basic elements of visual aesthetics is an important means to beautify the room. The selection of the light source is a direct impact on the artistic effect of the lighting, LED light color displayed on the display lamps art unparalleled advantages; color LED products cover the entire visible spectral range, and the color is good, high color purity, red, green select the yellow LED combination of color and grayscale (16.7 million colors) with greater flexibility. LED technology allows organic combination of scientific and artistic living room lamp, breaking the traditional lamp Collage frame, beyond the inherent concept of the so-called lamp shape, lighting design in the performance of visual perception and forms of artistic creativity, a new perspective to get to know, understand and express the theme of light. We can be more flexible use of optical technology in light and dark mix of light and color combination of materials, structural design advantages, improve the design freedom to weaken the function of the lamp lighting the lamps become a visual arts to create a comfortable and beautiful art of the light effect.

With the further maturity of the LED technology, LED will be fully embodies the development trend of the art lighting and humane, cultural dominant of the room lighting.

stealth led grow light reviews for solar use

With the development and progress of solar photovoltaic technology, solar cells as a new energy, first applied in the civilian aspects of the lighting, solar lighting products due to environmental protection and energy saving dual advantage. The solar LED lighting products is the next generation of green lighting products, and its main components, including solar photovoltaic cells (PV) and semiconductor lighting (LEDs). LED solar lights integrated solar photovoltaic and LED solid state lighting the advantages of solar LED lighting systems to achieve the perfect combination of a new generation of energy and a new light. However, in the design of solar lighting, involving light, solar battery systems, battery charge and discharge control of a number of factors, any part of a problem will result in product defects.

A first look at solar lighting composed of:
The key lies in solar photovoltaic technology and LED lighting (stealth led grow light reviews) a perfect combination of both direct current, low voltage and can be matched. The combination of the two do not need the solar cells produce direct current into alternating current, thus greatly improving the efficiency of the entire lighting system. The same time, by means of network technology or the use of battery charge and discharge energy, to make it more obvious advantages.
1, solar panels
2, the charge and discharge controller
3, the battery
4, the load
5, shell lamps

Second, the design used must be noted: (LED lawn lamps  (stealth led grow light reviews) , for example)

LED characteristics close to the Zener diode, the work of change in voltage 0,1 V, operating current of may change 20mA or so. For security, under ordinary circumstances, using a series current limiting resistor, a great deal of energy loss is clearly not suitable for solar lawn lamp, and LED brightness changes with the operating voltage. The boost circuit is a good way, you can also use a simple constant current circuit, in short, must be automatic current limiting, otherwise will damage the LED lights.

2, the peak current of the general LED 50 100mA, reverse voltage of about 6V, careful not to exceed this limit, especially in the reverse polarity of solar battery or battery no-load, high peak voltage boost circuit is likely to exceed this limit, damage LED (stealth led grow light reviews) .

3, LED temperature characteristic is not good, the temperature rises 5 ° C decreased by 3% luminous flux, summer should pay attention to.

The operating voltage discrete, the same model, same batch of LED street lightsoperating voltage has some differences, and should not be used in parallel. Must be used in parallel, you should consider are flow.

stealth led grow lights and led drivers

LED digital tube display use the drive circuit to drive the digital tube segment, which shows what we want, therefore, according to the different ways on the drive LED digital tube can be divided into static and dynamic categories .

A, static display driver:
Static drive, also known as the DC drive. Static drive means to each tube for each segment of code consists of a microcontroller I / O ports to drive, or use, such as BCD code - decimal decoder decoding to drive. The advantages of the static drive is programmed, the display brightness, the drawback is that takes up I / O ports and more, such as driving the 5 digit tube (stealth led grow lights)  static display, 5 × 8 = 40 I / O port to drive, be aware that a 89S51 microcontroller available the I / O port 32. Must be increased so the practical application of the decode drive to drive, increasing the complexity of the hardware circuit.

B, dynamic display driver:
Digital dynamic display interface is one of the most widely used microcontroller, a display, dynamic driving the all digital tube  (stealth led grow lights)  8 shows the stroke "a, b, c, d, e, f, g, dp" with the same name connected together, the other to increase the bit strobe control circuit for each of the tube very COM-bit strobe controlled by a separate I / O lines, when the microcontroller output glyph code, all digital tube received the same font code, but what is the digital tube will display the shape, depending on the control of the microcontroller strobe bit COM terminal circuit, so we just need to display digital tube strobe control open, the bit on the show the glyph, there is no digital strobe tube will not light.

Through time-sharing in turn control the COM side of each LED digital tube, so that in turn controlled display various digital tube, which is dynamically driven. In the rotation display process, per bit digital tube light time of 2ms, the human visual persistence of the phenomenon and the light-emitting diode (stealth led grow lights) afterglow effect, despite the fact that you number the pipe is not lit, but as long as the sweep The aim of speed is fast enough to create the impression that a stable set of display data, there will be no light flashes, the effect of dynamic display and static display is the same, can save a lot of I / O port, and lower power consumption.

Constant current driver with constant current driver on the LED digital tube is mainly the following:

1, showing the effect:
LED tube is basically a current sensitive components, the dispersion of the forward voltage drop large, and also with the temperature, you need to make it a constant current in order to ensure digital pipe has good brightness uniformity, and can not be temperature and other factors. In addition, when the temperature changes when the driver chips also can automatically adjust the size of the output current in order to achieve the temperature compensation of the color balance.
2, security:
Even short-term current overload may also cause permanent damage to the LED lights, digital tube, constant current drive circuit to prevent current fault extensive damage.
In addition, the Commission adopted VLSI characteristics of cascading delay switch to prevent reverse voltage spike damage on the light-emitting diode. VLSI also has thermal protection which automatically shuts down when any one temperature exceeds a certain value, fault indication and can be seen in the control room.

street solar lighting in LED machine

The jetting, belongs to the new led lights technology, which uses a nozzle alternative to syringes, to solve many problems. Jetting nozzles needed to fill the bottom of the device above the dispensing need to reach their location below the top (street solar lighting). Jetting nozzles in the entire circuit board side along the x and y directions, without the need for vertical movement.

And dispensing syringe, the nozzle does not form a continuous bottom-filling glue flow, and replaced every second jet more than 200 points after accurate measurement of the gel-point. With the move of the nozzle level, the gel-point can be the formation of linear and pattern of a variety of needs, the solid line, dotted line and a variety of other different graphics. Each jet by precise control of a jet formed by the gel-point minimum diameter of up to 0.33mm, for coating plastic patch area into the precise control of occasions is very important.

Injection technology is the glue from the nozzle at a faster rate, rely on glue momentum to make glue out of the nozzle. Each jet  (street solar lighting) will spray out a certain amount of glue. Common injection frequency is 100 Hz to 200 Hz, but will soon reach 1000hz. , There are several different jet dispensing needle dispensing. When the glue from the nozzle, before the glue in contact with the substrate and the separation nozzle. Each of the gel-point injection into the substrate to form points, lines, and graphics. In the dispensing position during the move, the dispensing head is not the movement of the Z-axis direction, thus saving a considerable amount of time. Needle dispensing robot in the X, Y, Z axis movement, glue flow from the needle out of contact with the substrate, relying on gravity and the substrate surface tension glue isolated from the needles. After the completion of each dispensing, a movement along the Z axis, and then move to the next dispensing position.

The LED products market is also benefiting from the spray adhesive technology. Spray adhesive process can spray a wide range of optical materials including silicone, UV curable conductive adhesive of the phosphorus doped in the high-speed dispensing position and precise dispensing and plastic volume control. The accuracy of the spray adhesive can improve the yield of high-value high-power LED street lights devices. Applied to the white light  (street solar lighting) production, phosphor powder and mixed glue dispensing, its consistency is a good improvement.

street solar lights in LED lumen

Increasing LED lights brightness can be broadly divided into two types, one is to increase chip itself, the amount of light emitted; Another method is the effective use of the light generated by the chip, increasing the exposure of the light irradiation to the expected direction.

The former is trying to improve the luminous efficiency of the chip active layer, as well as to improve the chip shape to increase the external light extraction efficiency, or chip, large-scale use of high current density to increase the amount of light emitted; the latter is the use of light wave control technology, that is, the package resin to form a special optical structure, the chip produced by light irradiation to the expected direction. If the LED (street solar lights) screen brightness of less than the expected value, you can also try using the following methods to improve the brightness after use.

(1) Changing the flow through the LED current, general LED tube  (street solar lights)  to allow continuous current at 20 mA or so, in addition to the red LED saturation phenomenon, the other LED brightness is basically proportional to the current flowing through.

(2) the use of the human visual inert gray scale control pulse width modulation method to achieve, that is, cyclical changes in the optical pulse width (duty cycle), as long as this repeated cycle of light is short enough , the human eye do not feel light-emitting pixels in jitter. LED display to provide a pulse width modulation is more suitable for digital control, so in general the use of computer content, almost all of the LED control system is usually composed from three parts of the main control box, the scanning plate and the display and control device. The main control box from the computer's graphics card to obtain a screen pixel colors and brightness information, and then re-allocated to a number of block scanning plate, each scanning the board responsible for controlling the LED screen on the number of rows (columns), and each row (column) on the LED display and control signal with the serial transmitted. There are two serial transmission of control signals: one is to scan the board centralized control of each pixel grayscale scanning plate from the control box of each line of pixel brightness value decomposition (Pulse Width Modulation) then the opening of the line LED signal  (street solar lights)  pulses (light does not shine to 0) to the corresponding LED on the line with serial transmission, control whether the light. Used in this way the device is less, the serial transmission of data in a repeating cycle of light, each pixel requires 16 pulses in 16 gray, 256 gray scale needs 256 pulses, the device operating frequency limit, generally only the LED lights screen to do the 16 gray.

1. The role of a plastic patch LED Lights
SMA, surface mount adhesives, for wave soldering and reflow soldering, and is mainly used to components on the printed circuit board, the general dispensing or stencil printing method to allocate in order to maintain the components in printed circuit position on the board (PCB), to ensure that components are not lost in the transmission process on the assembly line. Paste components into the oven or welder heating reflow sclerosis. With the so-called solder paste is not the same, after a heated hardening, and then heating it will not melt, thermosetting plastic patch process is not reversible. The use of SMT chip (super bright led headlamp) adhesive effect due to the thermal curing conditions, the connecting object, the equipment used, the operating environment differ. When used according to the production process to choose a plastic patch.

2, the composition of the plastic patch LED STREET LIGHT
PCB assembly used in the majority of surface mount adhesive (SMA) are epoxy resin (epoxies), although there are polypropylene (acrylics) for special applications. After high-speed dispensing system into the electronics industry to learn how to deal with a relatively short shelf life products, epoxy resins has become more mainstream glue technology worldwide. Epoxy resins generally provide a good adhesion on a wide range of circuit board, and has very good electrical properties. The main ingredients: the base material (ie, the main high molecular material), fillers, curing agents, other additives such as.

3, the intended use of the adhesive patch LED TUBES
a wave soldering to prevent the components off (wave soldering)
b. reflow to prevent the other side of the components off (double-sided reflow soldering process)
c. to prevent the components of displacement and stand at (reflow soldering process, pre-coating process)
d mark (wave soldering, reflow soldering, pre-coating), printed boards and components, bulk changes, marked with plastic patch.

4, adhesive patch used classification
a dispensing type: on the printed circuit board through dispensing equipment in Sizing.
b Squeegee type: the printing of steel mesh  (super bright led headlamp) or copper mesh coated scratch sizing.

The final temperature will affect the shape of viscosity and gel point, most modern dispensing machines rely on the needle mouth or chamber temperature control device to maintain temperature above room temperature of the plastic. However, if the PCB temperature increased from the preceding process, the outline of the gel-point  (super bright led headlamp) may be damaged.
