RGBW-LED projector with remote control

LED projector, which I initially bymistake mistaken for disco ball. Its main purpose is private parties, be it New Year, Halloween, birthday, and other shows. 9W declared power Able to shine with various combinations of red, blue, green and white. Among other things, declared "sound activation" - we check and see, as well as its other light properties.

Specifications
Voltage: AC100-240V 50 Hz
Power: 9 W
Modes of operation:
- Automatic
- Sound-activated
- Removed
Light source: 4 pcs. LED (RGBW)
Lighting color: RGBW (15 light effects)
Plug: EU / US / UK / AU plug
Dimensions: 86 x 100 mm
Appearance
The projector along with the components was packed in a cardboard box with a glossy color print. A little crumpled during transportation, but that's okay.

Completion is as follows:
- actually, the projector
- U-shaped holder
- remote control
- two screws
- brochure memo

The brochure memo gives technical information and the purpose of the remote control buttons.


The remote control comes with a tablet-type battery installed. This is a plus. Initially, a contact opening plate was inserted into the battery compartment. The dimensions of the remote 5h8.5sm. Buttons are signed.
The main functions that are available using this remote control are: (from left to right)
- ON / OFF - turn on / off the projector
- STOP / START - stop / start the rotation of the motor
- Music1 / Music2 - two projector response modes for playing music
- Up / Down Arrow - Adjusts the brightness of the LED.
- Motor Speed ​​- the speed of rotation of the motor
- AUTO - automatic mode
- A1-D15 - different glow modes separately


Fastening accessories. The holder is entirely made of plastic (although I thought it would be metal)

Dimensions:




Actually, the LED projector. I also expected it to be made of metal, but no - also plastic. The plug is correct. Cord length - 1 meter.


On the side of the case from opposite sides there are holes for fastening the complete screws. The dome of the lens is completely transparent.


The ball almost reaches the height of 100mm indicated in the lot, but in this case, it does not matter:


We analyze and look at the insides. The dome is fixed on the slots, so it is very easy to remove.

A translucent disk with a random relief is installed on the motor shaft, through which the light emitted from the light-emitting diode is randomly refracted


Disk temporarily removed. Under it is a LED with a collimator nozzle, a motor, a power board and an infrared receiver.


On the power board, in addition to the IR receiver, a microphone is soldered, which is used to change the lighting effects in time with the music being played.


The soldering of elements is manual, many of which are soldered crooked. 14-pin IC is not labeled

Diode bridge MB6F, P-channel transistor HA8121

The board with LED is an aluminum plate

The LED at first glance is one, in fact there are 4 of them - green, blue, red and white, if you look closely. Common anode.

The collimator cap, which covers this LED, is widely used in video surveillance systems to adjust the angle of illumination — which scattering angle this cap is designed for is not specified.

I have other attachments in stock, and they fit perfectly on this LED, but there is almost no profit from it.


Putting everything in place and fastening the holder

The weight of the assembled structure is 160 grams.

Power consumption ranges from 2.2W to 6.4W


Projector in work. How does he shine?



Just a photo of the ceiling with different color variations (photos are clickable):







The projector’s response to music isEssence winking light. The sensitivity of the microphone, I would say, is normal, does not respond to any sound, only to loud music. Below is a short video demonstration:

findings
The projector starts working immediately afterInsert the plug into the network. You can hear well how the plastic gears are spinning inside, and depending on which way to tilt the case, the sound of the gears becomes either quieter or louder. So using this projector as a night light and falling asleep with “colorful lights” will not work. If the projector is left connected to the network and turned off / on it via the included remote control, the internal memory saves the last played light animation mode. If you “pull” the power cord, then the last mode is not saved.
Walking alongside a working projector is difficult because the rays of light are very bright. It is necessary to direct in a certain direction so that the rays do not fall into the eyes.
The assembly is typical of cheap “Chineseness”, metal was expected, but then a bummer occurred. The toy works, but how long it will last, time will tell.
