The LED fill light is a solid-state light-emitting device, also called a light-emitting diode, which drives a semiconductor device to emit light by a small current, which consumes little power and is stable and high, but the brightness is relatively weak. Less heat and good heat dissipation. You can get close to the plant without making it anxious. Based on this feature, the LED can be placed horizontally or vertically above the plant, so it can greatly reduce illumination loss and provide light efficiency.
1, ED fill light principleA fill light is generally used to increase the amount of light used on the front of the subject.
The method of complementing. This kind of fill light is generally made of high-brightness light-emitting diode (LED), which has the characteristics of stable operation, low heat generation, low energy consumption and long service life! As for the parameters, they are generally not clearly marked in such products.
The so-called fill light is a special lighting device that projects a specific light to the object to be illuminated, directly or indirectly to obtain light. When used to promote plant photosynthesis, it is directly obtained by light; when used to improve the ambient illumination and improve the low illumination of the camera, it is a scene to be photographed by a specific light illumination, so that the camera can capture a good quality picture. Indirectly get light to make up. The light source of the fill light usually has LED, metal halide lamp, fluorescent lamp, high pressure sodium, incandescent lamp, iodine tungsten lamp, xenon lamp (HID) and the like.
Homemade small led fill light step 2, material preparation"The home of the science and technology man is a grocery store." In accordance with the principle of waste utilization and the best use of materials, the implementation rules for this fill light have been formulated. The overall materials are as follows:
Top left: LED light board (12V) (x treasure piece); bottom left: tinplate box (inventory); medium black: ship type switch (inventory); middle black next small: 3mm screw (stock); middle long strip of silver : 3mm thick 7075 aluminum plate (stock); upper right: 12.1v2200mah RC battery (performance drop into the cold palace); top right four white: nylon mount (stock); "T" plug (inventory); bottom right: thin wire (in stock).
In summary: In addition to the 12v lamp board needs to be purchased, other basic materials are basically complete, which is one of the conditions that contribute to DIY.
3, tools
"There is always one less tool in a man's toolbox." Yes, this is not a question that can be used, it is about integrity.
“Difficult tools make you angry, tools you can use to get the job done, and easy tools to let you enjoy life†– Mutian.
I am not a local tyrant. I don't have any expensive tools. I only have good tools. There are Makita in the office, a doctor, and a Fluke. I don't think it's better than my ken, devon and victor, the difference between 90 points and 95 points. For this 5 points, I have to double, triple and triple the price. Of course, I have to spend money to buy Dr. Makita Fluke, which is about the integrity.
This thing is not necessary, but after you have it, you can't live without him.
The quality of Chinese products, the old ones are recognized, which is more reliable than the fake white light table, although I can only use the head of foreign garbage.
4, the production process
This piece really doesn't want to write too much. If you don't have the technical content, you can put the light on it, use a switch, and connect it to the power. See the first volume of junior high school physics.
First make a comparison of this size, let the LEDs be fixed on the aluminum plate, and then fix the aluminum plate in the box.
Under saw
TIps: According to the old fitter and the mother, the small steel saw blade is divided into 18, 24, 32 tooth molds, sawing aluminum, this soft metal, preferably 18.
Lights, lights, etc. The point of the lamp is that it now advocates a kind of "high color rendering LED".
According to the highest instructions of the mother, look for a big number (although there may be moisture in it).
Then there is the color temperature, and the finished fill light now has a colorless change of 2700k~5500k (that is, adjust the different brightness of the two kinds of LEDs).
Give a chestnut: a 500 led fill light, 250 2700k orange led, 250 5500k white led, orange full bright, white all extinguished, is 2700k; white full bright, orange all extinction is 5500k; Orange white full light is 4100k (it is not estimated to be such a simple average, it will be spirited).
Having said that, I have solved this problem in a brutal and rude manner. The camera white balance is not vegetarian. The color temperature is gimmick, the boss, half white, half beer, what can't be solved. Can't solve it? Then half-white, half-beer
Four pieces of white and three pieces of warm white (beer) were used to position them on the aluminum plate.
Drilling
TIps: Do you know how big a hole is needed to make a 3mm tapped hole?
I don't know, anyway, I only have a 2.5mm drill bit, let's make it.
Drilling holes continue, thank you for using the vise.
Machine taps, directly mounted on the hand drill, tapping, retreating or to deal with it.
The light board should be close to the aluminum board, so the aluminum board should be opened with two countersunk pit mounting brackets.
That's it
The light board and the bracket are fully assembled.
Put in the box and try
The lid of the box cannot be wasted, and 2 lights are standard.
Dig a hole to install the switch, dig a hole, wear the wire, connect the lamp board in parallel, and install the "T" head on the wire. Time slipped away from the fingers and left a pile of mess. The final look is like this, 2 in 1 double lamp.
The lights are always set up to call the lights. How is it? ?
The bottom is 1/4 thread and can be mounted on a tripod with a variety of clip openings. First bui2 come over.
