Description

A kind of green illumination is met an urgent need dual-purpose lamp and control method
Technical field
The present invention relates to illuminator technical field, particularly to a kind of normal illumination and the dual-purpose lamp of fire-fighting emergent.
Background technology
Along with the continuous propelling of China's urbanization, skyscraper and intelligent building development are swift and violent, fire fighting problem is also following, is deeply paid attention to. Fire emergency lamp has become a requisite part as a fire fighting linkage equipment in residential houses. According to the regulation of " Code for fire protection design of buildings " GB50016-2014, building height is not less than the places such as the staircase of the high residential building of 27 meters to be needed to arrange emergency lighting.
A lot of deficiency is there is in current fire emergency lamp from the angle of practical. First, traditional double end fire-fighting emergency headlamp is mostly with the glow discharge spot lamp such as electric filament lamp or fluorescent lamp for light source, and power consumption is relatively big, is unfavorable for energy-conserving and environment-protective. Second, fire emergency lamp only works when normal power source breaks down, and its function singleness is in idle state at ordinary times. And the place being commonly installed fire emergency lamps also can install ordinary luminaire, so cause the repetition and waste of light fixture. 3rd, owing to the time of fire emergency lamp work is shorter and uncertain, thus easily it is negligent of maintenance by staff, once occur urgent feelings possibility to play a role, with hidden danger. 4th, adopt the fire emergency lamps of EPS (emergency power supply) centrally connected power supply, powered by 220V alternating current power supply at ordinary times, run into fire etc. in emergency circumstances to need the DC inverter that EPS set of cells exports by inverter to be AC-powered, therefore run into the water of fire-fighting water spray device ejection by extremely dangerous. 5th, requirement according to " Code for design of automatic fire alarm systems " GB50116-2013, the power conditions of fire-fighting emergency headlamp tool should be monitored in real time, but on front market, most fire emergency lamps does not have this function, also cannot unified monitoring.
And the place installing fire emergency lamp generally also needs corridor lamp. Both this, difference is very many, and what time relevant to this patent is summarized as follows:
Illumination requirement is different, and normal illumination generally requires 50lx illumination, and emergency lighting generally requires 5lx illumination, differs 10 times, but staircase often narrow space, whether normal illumination or emergency lighting, it is both needed to a set of light fixture and just can meet illumination requirement.
Power supply is required difference, mainly emergency lighting requirement accumulator makes emergency power supply, and accumulator capacity should be able to meet institute's band light fixture working time and be typically no less than 90 minutes, the voltage condition of accumulator to be subject to the monitoring of fire-fighting power supply monitoring system, and normal illumination no requirement (NR).
Controlling to require difference, normal illumination uses under normal circumstances, it is possible to adopt manually, acousto-optic, infrared etc. control mode realize lighting and extinguishing of light fixture, and emergency lighting uses in case of fire, forces to light after receiving fire-fighting signal. Use when the two is different.
At present in practical engineering application, normal illumination and emergency lighting are generally adopted following two control mode:
Adopt the two completely self-contained systems of set, the respective function of respective complete independently, be independent of each other. But investment is big, the wasting of resources, and in a narrow space, adopt two set light fixtures also unsightly.
Set of system is adopted to complete two kinds of functions, it is possible to adopt light fixture to carry accumulator, or by the unified power supply of the accumulator battery of concentrated setting, i.e. EPS. Owing to being share light fixture, lamp power requires configuration according to normal illumination, then accumulator capacity is unavoidable improves 10 times, and investment increases.
It addition, both the above mode must join outward fire-fighting power supply monitoring system to monitor the voltage condition of accumulator. And accumulator effect when non-fire incident can not be given full play to, there is huge problem of resource waste.
Summary of the invention
The present invention has designed and developed a kind of green illumination and has met an urgent need dual-purpose lamp, solves normal illumination lamp and fire emergency lamp is independently arranged the defect causing the wasting of resources, makes emergency light and corridor lighting two-in-one, saves Financial cost.
It is a further object to provide a kind of lamp brightness control method, make when fire occurs the brightness of light fixture meet lighting demand and there is the longer working time simultaneously.
