From 5-bottoms make the syringe container for batteries. Solder to the design of the container with battery. Then attach using a soldering iron to the hood blue and red LEDs. Pass the wire through the hole on the plastic sleeve. On the plastic cap on top put a plastic sleeve. By withdrawing from the coupling wire, attach a small toggle switch. Check the operation of the mechanism established by setting the switch to a different position. Screw design instead of a shower or faucet. When the hot water is turned on, it should be highlighted in red, and when the cold, it is blue.

To make a 5-bottoms syringe container for batteries, need copper foil, wire, glue gun with, the battery itself and the syringe. To begin, cut with a knife tip of the syringe and pull the wires through the body of the syringe. At the bottom of the copper foil preform place. Cover the glue nozzle of the syringe to the wire, and the second route the transactions through the piston, connecting it with the copper contacts. Place the syringe button-type battery and a container ready.

LED Spotlights Outdoor and Indoors

Today, LED spotlights are the ideal lighting solution for modern cities, streets, buildings, bridges, billboards, parking lots of storage space and adjacent areas. These light sources were an indispensable tool to create a unique image of the city, accents, show and highlight the beauty of the historic buildings, as well as the scale of buildings. LED spotlights are the modern replacement of legacy projectors with halogen and metal halide lamps. LED floodlights provide bright and directional light, with maximum energy saving, long service life, high degree of protection against mechanical damage and environmental influences and does not require additional maintenance costs.

Consider the unit LED spotlights on the example of a model from one of the well-known manufacturers of 50 watts. Modern LED spotlights (e.g. 10W LED Chip Lamp) from top manufacturers available in modern and functional packaging with bright memorable design, which distinguishes them from noname products. Spotlight housing and is usually made of a cast aluminum alloy having a high thermal conductivity, which allows heat removal from the LED module. The reflector is typically made of metal. With coated aluminum deposition in a vacuum creates an even light output with given scattering angle, providing high consumer properties of the spotlight. Silicone seals and grooves on the spotlight housing provide high protection of electronic components against moisture spotlight.

These models are designed for outdoor use. Cheap as spotlights unknown manufacturers have moisture protection at this level. Moreover, the poor quality of the assembly can be clearly seen with the naked eye. Housing of high-quality LED spotlights usually has a special anti-corrosion powder coating that provides protection against mechanical damage and environmental impact (e.g. water does not linger on the body as opposed to the usual smooth coat). The modern LED spotlights used inside the housing are located LED module made on the chip on board technology (COB). The diffuser is made of clear tempered glass.

LED spotlights do not require additional services, which allow to minimizing the costs of their operation. Swivel bracket makes it easy to install the spotlight, as well as direct the luminous flux in the desired direction. BTW, you can select the in ground flood light at Banggood. Besides, you can easily get other LED lighting accessories (e.g. 5V light bulb) there with high quality and reasonable prices.

How to Connect LED Strip

Backlight LEDs actively spreading in modern design. LED strips are used in various fields. For example, LEDs are used in the interior spaces of buildings. The shop windows are also illuminated lights from LEDs in cars are also used LED strip. Low cost, practicality and easy installation LEDs have provided widespread.

You will need

- IP65 LED Light Strip

- Power Supply

- Scissors

- Soldering iron

In the beginning, you need to decide on the venue installation LED strip and calculate the length of its future. One must remember that the LED strip can be cut through multiple intervals (for example, SMD 3528 Q60 tape can be cut every 5 cm), so you need to take this into account in the calculation.

The next step is the selection of the power supply. The power supply must strictly conform to the stated capacity of the tape. In the selection of the block is best to consult with a professional advisor, not to be mistaken.

After all, the components purchased to prepare the surface for the tape mounting. Mounting location carefully degreased. It is better if the surface is solid (in order to avoid damage to the tape PCB). If the tape be mounted on metal or other conductive surfaces, the tape must be isolated. If the tape does not need to cut, it is immediately ready for installation. LED strips have a back side of the adhesive layer. With this adhesive layer and made assembling strip. The protective coating is removed and the tape pressed against the surface. BTW, you can select the LED strips at Banggood. Besides, you can easily get other LED light (e.g. stainlesss teel wall mounted solar light) there with high quality and reasonable prices.

The final step is to connect the tape to the power supply and controller, which is produced by wires from the tape. Each wire has its own designation on the conductive path, R, G, B, and V +, and connected respectively polarity to 4 inputs on the controller R, G, B, V + .Blok power to 220V connect the two wires to terminals L + and N-. Next, connect the "+" on the power supply to the "+" on the controller, and "-" to "-", respectively. Voltage polarity must not be confused - this can lead to equipment failure and damage to the tape.

Installation of LED Ribbon on the Car

Until a few decades ago, LEDs were only used as indicator lights. But today, thanks to its characteristics, versatility and beautiful glow, LED-technology every year are gaining popularity in the field of lighting. Consumers are increasingly moving to the use of LED lamps and luminaires, as well as LED strips, which have been applied in advertising and decorative lighting, and actively used by designers all over the world.

In addition to the design goals of interior room lighting, LED strip steel (e.g. the 12V LED strip lights) is widely used in the automotive industry, to enhance the standard lighting cars. Some manufacturers of modern cars already in the basic equipment of the models set the LED backlighting in size and dashboard. However, for many motorists, who want to give your vehicle a unique look and add functionality to the standard interior lighting, boot or body, this is not enough. So they resorted to self-tuning of the car, using the LED strip, by which additional lighting can be set in the most unusual places, even where it did not exist before.

For successful device further highlight the car must follow these steps:

1. Determine the place of installation of LEDs;

2. Cut the tape only in the right place;

3. Qualitatively fulfill its connection to the onboard network.

There are two ways to connect the LED strip: no interference in the electric car circuit and with a hole in it. When laying the tape should be selected segments of the desired value, which are cut to the ground and fold sequentially connected together by soldering the wires through the connectors. It is necessary to strictly observe the polarity, but in the case of improper connection LEDs will not go down. If the light does not work, you will need to check the correctness of the connection. Places soldering, to prevent ingress of water, treated with silicone. Connect LED ribbon through the controller (in the passenger car - 12 V) to the power supply using the adapter into the vehicle's cigarette lighter. To this end, a standard telephone charge soldered wires from the LED strip, with one wire is fixed to a fuse, and the second - bypassing the regulator to rule with an iron lug. And you can use the RGB LED connector.

To implement the second method of connecting the tape with a hole in the car's electrical circuit, only need two additional wires. In order not to reverse the polarity, it is best to use the red and black wires. Red is soldered to the "plus" ribbons, black - a "minus". And then solder joints should be treated with sealant. Black wire is held under the skin to the negative terminal of the battery and the red through the switch - to the positive. The switch is installed inside the vehicle so that it to be easy to get.
