The tunnel light is a kind of light-efficiency energy-saving lamp. It uses
light-emitting diodes
(
) as the light source of the luminous body. It has high light efficiency and long life. It can be realized with different reflectors. Multipurpose lighting that is softened and will not cause dazzling or other uncomfortable reactions.
Ballast
Select overheat protection technology to ensure the service life of the lamp. Imported high-purity
mirror aluminum
anodized
material is used as a reflector and is designed with precise light distribution
,
the power factor is greater than
, and the reflective efficiency is high. Good light transmittance, energy saving and environmental protection.
Comparison with traditional
tunnel lighting
Light source
It is a solid-state semiconductor device that can directly convert electricity into light, compared with traditional road tunnel lighting
Light source
(sodium lamp
,
metal halide lamp

, etc.)
,
light source
has the following advantages
The light attenuation is small. If the heat dissipation conditions are good, the
front
light attenuation is positive
, and the
front
light attenuation is

One

, the former
is basically
,
far lower than the ordinary
road lighting
light source, the light is more stable .
Color rendering
High generally
Color rendering is about
~
, if using
Three primary color phosphors
it will be higher.
High-pressure sodium lamp
is
~
,
low-pressure sodium lamp
is lower, so even if the brightness of the traditional light source is higher than
, the visual effect is poor So
,
not the brightest, but the clearest to see
This should be a direction for the development of
light source
applications.
Lifespan
The lifespan of lighting sources
is higher than that of general road tunnels
, and is now generally higher than
.
Tunnel lights are suitable for large-area lighting in tunnels, workshops, large warehouses, venues, metallurgy and various factory areas, engineering construction, and other places.
