Did you know that blue lasers can also repel birds?
Birds, especially herons and pigeons, are highly sensitive to the blue light band around 450nm. Blue light strongly stimulates their retinas and visual nerves, causing intense discomfort and fear, triggering the instinct of "danger approaching" and making them fly away voluntarily.
At night, blue light forms a clear and continuous light column or light wall, which birds perceive as an insurmountable physical barrier and dare not enter the covered area.
Compared with traditional methods such as sound waves and scarecrows, the blue light stimulation mode can be adjusted through frequency flashing and scanning speed, making it difficult for birds to adapt and ensuring a more lasting bird repelling effect.
Take the HIZ-SP-NLG intelligent laser bird repelling device from Guangxi Haizhuo Technology as an example. Its light beam emitter is the core emission technology unit of the system, emitting blue light beams to repel birds in the area. The advantages and features of this device are as follows:
Strong effect and wide coverage: The effective coverage radius at night can reach over 500 meters, and the repelling rate for large birds such as herons can reach 98%.
Safe and environmentally friendly: Non-contact, no chemical agents, and no harm to birds; compliant blue light is harmless to human eyes and does not disturb the public.
Intelligent and controllable: Supports 360° automatic scanning + manual remote control, can remotely direct the repelling of sudden bird flocks; parameters can be adjusted according to different seasons and bird habits.
All-weather stability: Wide temperature range (-20°C to 60°C), low energy consumption, suitable for long-term monitoring scenarios such as airports, substations, and photovoltaic power stations.
