We have been selling a selection of poultry lighting controllers for many years now – devices designed to stimulate egg production in the winter months using artificial light at dusk and/or before dawn to trick the birds.

Pictured below is a bespoke lighting controller we recently made for a more advanced poultry lighting controller including a double voltage regulator so that more LED bulbs can be used in a large poultry house, an automatic low voltage disconnect, and an LCD display to show system status and for use in setting up the system.

This device will automatically detect dusk and turn on the lights in the poultry house for a user-programmable number of hours (including zero). The lights then turn off (if they had been on) and remain off for 9 hours to give the birds a 9 hour sleep and a 15 hour day for maximum egg production. The lights then turn on in the early morning and remain on until dawn when natural light is bright enough to take over.

Dawn and dusk are detected using a light dependent resistor, and the user can calibrate the exact light level which they consider to be at the threshold between day and dusk, and between night and dawn.

To protect the battery from being run too low of charge and being damaged, the user can programme into the device three trigger voltages: a voltage below which the on board red LED will turn on as an early warning, a voltage below which the output (to the lights if on) will be turned off, and a voltage above which the low voltage disconnect will be cancelled restoring the outputs automatically when the battery is recharged.

There is also a manual override option which enables the lights to be turned on manually at any time (low voltage disconnect permitting) when the poultry house needs to be cleaned or the eggs to be collected etc.

At all times the backlit LCD display shows the status of the system including the currently measured battery voltage, whether the LVD is engaged, whether the outputs are on or off, the current position in the cycle DAY, DUSK, SLEEP, PREDAWN, DAWN (or MANUAL when the override is active), and the currently measured light level relative to the user set threshold.

If you need any kind of poultry lighting solution, please email neil@reuk.co.uk with details of your exact requirements and we should be able to put something suitable together for you.
