Photometrics of Poultry House Light Knowledge

Farming lighting is an emerging special lighting product with its own engineering characteristics.
1. Matrix installation, the wire length is relatively long.
Considering the safety, reliability and comprehensive use cost of installation and use, low-voltage 48V power supply is currently generally used. Because long-distance power transmission of wires will cause heat loss and line voltage drop. Traditional resistor current-limited lamps will produce serious inconsistency in front and back brightness. In view of this, we, Ji Diao Optoelectronics, took the lead in researching and inventing distributed constant current dimming technology, which perfectly solves the problem of inconsistent brightness of lamps under different voltages. The theoretical simulation effect can achieve the ideal effect shown in the figure below.

2. Stereoscopic vertical lighting, with a large drop from top to bottom. For a typical hoisting cage installation method, the distance between the top cage and the lamp tube is generally less than 1 meter, while the height of the bottom feed trough is often more than 3 meters from the lamp tube.
The illumination of the lamp tube and the distance from the lamp tube have the following relationship:
Illumination = light source brightness (cd) / square of distance (m^2)
That is: the illumination value of the test point is inversely proportional to the square of the distance to the lamp tube. According to this formula, it can be roughly calculated that the illumination ratio of the bottom feed trough 3 meters away from the lamp tube and the top feed trough 1 meter away from the lamp tube is 1:9, which is also the case in reality. This will cause the illumination of the top feed trough to be too high, which will seriously affect the growth of the chickens. And the illumination value of the bottom feed trough is too low, and the chickens can't even see clearly when eating, which affects their growth and development. Another original technology used by the lamp tube is to distribute the light twice, so that the illumination of the upper and lower cages is also highly consistent. There will be no situation where the illumination of the top layer is too high and dazzling, and the bottom is too dark to see the feeding. The perfect combination of the two technologies ensures that there are no dark areas in the entire shed, achieving perfectly uniform illumination from front to back and from top to bottom.
