High-brightness LED be the 4th generation electric light source, have light efficiency height, photochromic complete, advantages such as light modulation is good, response speed is fast, anti-seismic performance is strong, safety and environmental protection, the life-span is long, size is little, can be applied in various colours and white illumination field.Led light source can energy savings when promoting lighting quality and effectiveness, improves environmental pollution, the harmonious development of beneficial to national welfare and the people's livelihood.
How utilizing resource effectively fully, save the cost of system, is the emphasis of a lot of scientific and technical personnel's researchs.Although various fire emergency schemes are arranged at present, and its characteristic is arranged respectively, with new technology in conjunction with aspect still be weak.Disclosed patent ZL201220009748.4, be a kind of primary-secondary type centralized control LED fire emergency and evacuation indication system, connect a plurality of female light fixtures with Centralized Controller by communication modes, be equipped with female lamp control circuit in each female light fixture, though its advantage is arranged, but for requiring simple and reliable fire-fighting to throw light on, seem complicated.The reliability of modern electronic product and its complexity have close relationship, as long as can realize the function of regulation, circuit is more simple, and the components and parts of use are more few, and reliability will be more high so.
The purpose of this utility model is to propose a kind of fire emergency switching device shifter, under the prerequisite that does not influence normal illumination, it is energy-conservation and be easy to the advantage of high effective controlling light to give full play to the LED light fixture, by suitable control, under the situation of fire-fighting emergent, utilize the light fixture of normal illumination, be automatically converted to standby lighting or escape lighting.
Summary of the invention
The purpose of this utility model is to propose a kind of fire emergency switching device shifter, under the prerequisite that does not influence normal illumination, it is energy-conservation and be easy to the advantage of light modulation to give full play to the LED light fixture, by suitable control, under the situation of fire-fighting emergent, utilize the light fixture of normal illumination, standby lighting or escape lighting are provided.
The utility model is achieved in that a kind of fire emergency switching device shifter, it is characterized in that, comprising: AC-DC power supply 1, DC-DC power supply 2, ultra-high brightness LED array 3, relay K J1, switch S 1; Switch fire emergency and normal illumination by relay K J1; By switch S 1 standby lighting or escape lighting are set.
Described AC-DC power supply 1 is to be converted to the galvanic Switching Power Supply of LED illumination by the power frequency civil power, and input has been carried out electrical isolation with output by high frequency transformer.
Described DC-DC power supply 2 is the PWM light modulation power supplys that are converted to the LED electric consumption on lighting by the fire-fighting DC power supply, and input has electromagnetic interface filter, and output is the PWM voltage of no filtering.
The utility model uses above-mentioned critical piece to constitute according to above-mentioned design.Its operation principle is: when normal illumination, by AC-DC power supply 1 the power frequency civil power is converted to LED illumination direct current, supplies with ultra-high brightness LED array 3, change the electrical power that obtains into luminous flux by ultra-high brightness LED array 3, normal illumination is provided; When fire emergency, the fire-fighting control system provides the fire-fighting DC power supply, relay K J1 is subjected to this power supply control and gets electronic work, its transfer contact has been received ultra-high brightness LED array 3 with the output of DC-DC power supply 2, because the output of DC-DC power supply 2 is PWM voltage, and the luminous flux of ultra-high brightness LED array 3 outputs is directly proportional with the duty ratio of PWM voltage, therefore, the luminous flux of LED light fixture output is variable, and brightness and illumination are also variable; Switch S 1 can be controlled under the mode that DC-DC power supply 2 is operated in high duty ratio or low duty ratio, corresponds respectively to standby lighting and escape lighting, to adapt to the lighting requirement of different application targets and different use occasions.
Advantage of the present utility model and effect:
(1) same set of light fixture both can be used for normal illumination, also can be used for fire emergency, had reduced installation quantity and the maintenance cost of light fixture.
(2) can be set to standby lighting or escape lighting by switch easily, take into account different use occasions and different application targets.
(3) use the PWM dimming mode to regulate the brightness of LED lamp, the efficient height is conducive to energy-conservation.
(4) simple in structure, cost is low, the reliability height.
