1.Cast light lamps, which specifies the illuminance on the illuminated surface is higher than that of the ambient lighting. Also called the spotlight. Usually, it is able to aim at any direction, and have not affected by climatic conditions affecting the structure. Mainly for large field operations mine, building outline, stadium, overpass, monuments, parks and parterre. Therefore, almost all of the outdoor use of large area lighting can be thought of as cast light lamps. Light emitting angle of a beam with a narrow width, changes in the range of 0 to 180 DEG between beam, which particularly narrow called searchlight.
Advantage:
Advantage:
1, the internal and external anti earthquake structure design, effectively solves the strong vibration caused by shedding light bulbs, lamp life shortening, stent fracture problems. 2, in an efficient gas discharge lamp as the light source, lamp with long service life for more than 10000 hours, especially suitable for outdoor large area unguarded lighting. 3, made of light alloy materials and high-tech spraying technology, the shell will never rust, never corrosion. 4, using new technology such as piping, secure shell good integrity, reliable sealing, waterproof and dustproof. In 5, has a good electromagnetic compatibility, not on the surrounding environment caused by electromagnetic interference. In 6, whole lamp heat dissipation is good, can reduce the probability of failure.
