HOW TO REPLACE THE LIGHT BULB ON THE LED TAPE WITH YOUR OWN HANDS
ITEMS CAN BE REPLACED LAMPS WITH A STANDARD LAMP, FOR EXAMPLE, WITH A WALL-MOUNTED LAMP. IN ADDITION, THE OPPORTUNITIES OF SUCH TAPES ALLOW YOU TO ORGANIZE MORE AND BACKLIGHT NISH.
At one time, three lamps were installed in the hallway of my apartment for lighting: two half-round ones on the walls and one round on the ceiling. They were intended for incandescent lamps with a power limit of 60 watts. During prolonged operation, the lamp warmed noticeably. The cartridge inside, the insulation of wires, transitional pads gradually became fragile.
NOT SO LONG AGO
With the advent of fluorescent lamps, I replaced all the accessories and got rid of incandescent bulbs. But the space inside the luminaire made it possible to install a lamp of only a small size, and even that very quickly lost its original brightness.
The lamp was also heated, but not as much as the incandescent lamp.
RECENTLY
I had some initial experience with LED tapes. To illuminate the cabinet with dishes, I bought a ready-made set of -5 m tape and a 12 V power supply, 40 W power with connection wires and a switch on the network cable. After the completion of this work, a piece of tape 1 m long remained. And he did not give rest - I wanted to attach it somewhere.
The base of the ceiling lamp in the hallway, which had to be modernized, is a metal bowl with technological holes. It is mounted on special brackets electrical fittings for connecting a lighting lamp.
Dismantled all fittings. For this it was enough to unscrew the screws.
CALCULATION OF POWER OF POWER SUPPLY LED LAMP
Not every LED tape has a comprehensive marking on the body (body) of the tape.
I installed 100 cm of smd 5050 tape on 12 V, 30 LED / m with a consumption of 7,2 W / m in the lamp. The power source for it must be at least 10 watts. Understanding the problem, I found out that the price of a 12-shaft unit differs from the price of a 25-watt unit by 10-20%. I bought a block with a power of 25 W for 12 V, IP20, dimensions - 78 x 48 x 20, price -475 rubles. (from different sellers 400-500 rubles.) Such a source can power another 2 m of tape.
Therefore, I decided to make the highlight of two niches in the hallway above the interior doors. To do this, I bought an additional 2 m 4,8 tape W / m, 60 LED / m (168 rub./m) and an aluminum profile for LED strip (228 rub./m).
When all the tapes are connected, the load on the source will be: 7,2+ 4,8 × 2- 16,8 W.
In this mode, our source will work in comfortable conditions.
COLLECTING UPDATED FIXTURE
On the side walls of the metal bowl of the plafond, two rings of LED strip of the total length 1 m fit. The tape has a self-adhesive base. The place on which we will stick the tape, you need to wipe with alcohol and dry with a clean dry cloth. The protective tape from the adhesive layer should be removed gradually, as the LED tape is glued to the ceiling of the ceiling.
The tape must be leveled and pressed with force to a metal surface. Especially carefully - in the corners. The bending radius of the tape is enough to lay it tightly, without gaps throughout the semicircle. A well-laid tape ensures normal cooling of the LEDs and resistors located on it. And the case plays the role of a good heat sink. I soldered the wires to the tape with a small soldering iron and insulated with a heat shrink tube.
The power source was fixed through a technological hole in the body of the lampshade with an M3 screw. The power supply has six threaded mounting holes - two in three planes of the housing.
To connect the 12 B power supply to the ribbon in the luminaire, a special connector (clip) was used, when clicked, the needle contacts pierced the ribbon, forming a secure connection. The kit includes several conductors with clips. Wires connected to the power source through its terminal block with screw terminals.
At connection of wires it is necessary to observe polarity. The terminals on the block are clearly labeled. Marking is also indicated on the LED strip.
Before installation, the ends of stranded conductors must be gouged or tubular sleeves must be used.
BACKLIGHT NADDLE BOXES
To illuminate the door frames, I made two lamps - 80 and 120 cm long. For reliable operation, I installed the LED strip on a metal aluminum profile with a protective diffuser and acting as a radiator.
This aluminum profile for LED strip can be purchased at an electrical goods store. The profile has holes for mounting it with screws. It can also be fixed with special clips or glued to glue or mastic.
The opaque plastic screen (lens) and the caps installed in a profile protect a tape from dust. At the expense of the screen, the light is soft and diffused.
Naddvernye boxes are located on the same wall to the left and right of the semicircular wall lamp, in which the power source. The tape in the naddverny boxes connected to this source with flexible wires.
The light comes on together with the lamp on the wall with a switch from the original place of the hallway.
