LED corn lamp is a kind of lamp whose illuminance on the illuminated surface is higher than the surrounding environment, also known as a spotlight. It is mainly used in large-scale operation field, mine, building Du object outline, stadium, overpass, monument, park and flower bed, etc. Therefore, almost all outdoor large area lighting lamps can be regarded as LEDs.
The LED corn lamp consists of three parts.
The LED is composed of optical components, mechanical parts and electrical components.
The optical components are mainly reflectors and light limiting panels.
The main mechanical components are the shell, the focusing mechanism for fixing and adjusting the position of the light source, the bracket and base for fixing the lamp, and the parts with angle indication for adjusting the beam projection direction of the lamp.
The main electrical components are ballast, capacitor, trigger, etc.
The main features of LED corn lamp are as follows:
In order to improve the durability of lamps and reduce the workload of maintenance, people pay more and more attention to the development of airtight LEDs with higher one-time investment cost.
In order to further improve the light output ratio of lamps and lanterns, the reflectors tend to adopt the block reflector which can reduce the light barrier of the light source and the multifocal reflector which can meet the special lighting requirements.
In order to lighten the lamp weight and reduce the consumption of metal materials, the shell of the lamp will develop towards the plastic shell with high-temperature resistance, high mechanical strength and anti-aging.
