Summary of the invention
The utility model provides a kind of flame proof tunnel lamp based on LED light pipe technology for the flame proof tunnel lamp that solves the existing LED of application fluorescent tube increases the glare problem that exists because of the LED fluorescent tube uses power.
The utility model is to adopt following technical scheme to realize: the flame proof tunnel lamp based on LED light pipe technology, and comprise the flame proof lamp housing, place the fluorescent tube in the flame proof lamp housing, the flame proof lamp housing comprises the flame proof cover, is arranged at the flameproof enclosure of flame proof cover end; Described fluorescent tube comprises the transparent light guide pipe, is fixed in the led light source at transparent light guide pipe two ends by mount pad respectively, be provided with the optical lens that places before the led light source in the mount pad, and led light source is equipped with radiator; The axial direction of transparent light guide pipe outer wall upper edge transparent light guide pipe is coated with the reflecting coating layer, and the radian measure alpha of reflecting coating layer should satisfy: π/3＜radian measure alpha＜2 π/3; The transparent light guide pipe places in the flame proof cover, and each parts of end place in the flameproof enclosure, and are provided with the driver module that is used to drive the two-terminal led light source works of transparent light guide pipe simultaneously in the flameproof enclosure.
Before drop into using, a side that requires flame proof tunnel lamp transparent light guide pipe is coated with the reflecting coating layer is installed the lane wall at lamp place, flame proof tunnel in the tunnel; When illumination is provided, the led light source at lamp transparent light guide pipe two ends, flame proof tunnel is luminous under driver module control, and after the light that led light source sends reflects via optical lens, oblique incidence transparent light guide pipe, in the transparent light guide pipe, produce diffuse reflection, the direct transmission transparent light guide of part light pipe, another part light is transmission transparent light guide pipe after the reflecting coating layer reflection of transparent light guide pipe outer wall coating, redistributed the emitting light path of light, the light that makes led light source send can be via the even outgoing of transparent light guide pipe, make emergent ray very soft, therefore can effectively eliminate dazzle, avoid the dazzle illumination.Even for satisfying the illumination requirement of downhole monitoring system, improve the use power of led light source, based on the effect of redistributing to the beam projecting light path of the reflecting coating layer of transparent light guide pipe and outer wall thereof coating, flame proof described in the utility model tunnel lamp still can effectively overcome glare problem.
Wherein, the main effect of radiator is in time to dissipate the heat that led light source and its driver module produce, and the temperature of led light source is controlled in the certain numerical value, effectively avoids Yin Wendu too high and shorten life-span of led light source, also can guarantee the driver module reliably working; For reaching better heat radiating effect, radiator easily selects for use metallic aluminum material to make.
The main effect of flame proof lamp housing is to cause gas explosion when avoiding led light source and its driver module electric spark to occur.Its structure and common flame proof tunnel lamp are identical, all are made of flame proof cover and flameproof enclosure.
The effect of driver module is for led light source provides constant current, when input voltage when wide range changes, guarantee that the intensity of light of led light source is constant.And the driver module of direct led light source on sale on the market, structure is various, price does not wait, and the technical staff can select according to concrete needs; In addition, in order not influence grid supply quality, the power factor of driver module must be greater than 0.9.
The utility model is rational in infrastructure, compact, and result of use is good, can effectively overcome the common LED fluorescent tube and use power to increase the glare problem that exists, and have long, advantage such as economize on electricity is remarkable, pollution-free of life-span simultaneously.
