Abstract
A coal mine downhole emergency LED roadway lamp capable of adjusting output power belongs to the technical field of coal mine downhole illumination equipment and aims to solve the problem that the existing coal mine downhole LED roadway lamps with delay emergency illumination functions can only supply emergency illumination time of ten minutes. The technical scheme includes that a joint J3, an LED 1 , an LED2 , an LED 3, an LED 4, an LED 5, an LED 6, an LED 7, an LED 8, an LED 9, an LED 10, an LED 11, an LED 12, an LED 13, an LED 14, an LED 15 and an LED 16 are in series connection with a joint J4 sequentially; and a joint J8, the LED 15, the LED 13, the LED 11, the LED 9, the LED 8, the LED 6, the LED 4 and the LED 2 are in series connection with a joint J7 sequentially. The coal mine downhole emergency LED roadway lamp has the advantages of being capable of delaying emergency illumination time by adopting special circuit design and wiring structures on the premise of keeping battery capacity constant.
Description
Technical field: the utility model relates to technical field of lighting fixtures under the coal mine, is the LED tunnel lamp that a kind of underground mine use is adjusted power output when emergent more specifically.
Background technology: the LED tunnel lamp of the band time-delay function of emergency illumination that uses under the coal mine at present, limitation because of the flame proof functional design requirements, the space of leaving emergency lighting battery for is less, cause battery capacity little, tens fens kind emergency lighting time generally can only be provided, and circumstance complication under the coal mine, various functions tunnel is crisscross, in case fortuitous event occurs, escape and rescue all need the time longer than ground, and tens fens kind emergency lighting times can't be satisfied the needs of particular surroundings under the coal mine.
Summary of the invention: in order to overcome above-mentioned shortcoming, the purpose of this utility model is to design the LED tunnel lamp of adjusting power output when a kind of underground mine use is met an urgent need.Its design is: contact J3, LED1, LED2, LED3, LED4, LED5, LED6, LED7, LED8, LED9, LED10, LED11, LED12, LED13, LED14, LED15, LED16 and contact J4 are connected in series successively; Contact J8, LED15, LED13, LED11, LED9, LED8, LED6, LED4, LED2 and contact J7 are connected in series successively.The advantage of this utility model is: use special circuit design and wire structures, under the situation that does not change battery capacity and volume, when making light fixture transfer emergency lighting to by normal power supply, emergent power output is adjusted into half of former power automatically, thereby under the constant situation of battery capacity, guarantee suitable illumination, prolong the emergency lighting time, provide illumination for escape and rescue to greatest extent.Rationally reliable circuit design and wire structures, when making light fixture transfer emergency lighting to by normal power supply, emergent power output is adjusted into half of former power, prolongs the emergency lighting time.As light source, as driving, saved the energy with LED with high efficiency constant-current source.
Description of drawings: this accompanying drawing is the utility model circuit diagram.
Embodiment: contact J3, LED1, LED2, LED3, LED4, LED5, LED6, LED7, LED8, LED9, LED10, LED11, LED12, LED13, LED14, LED15, LED16 and contact J4 are connected in series successively; Contact J8, LED15, LED13, LED11, LED9, LED8, LED6, LED4, LED2 and contact J7 are connected in series successively.Insert the 127V AC power under the normal condition after rectification, constant current, it is all lighted and operate as normal for LED1, LED2, LED3, LED4, LED5, LED6, LED7, LED8, LED9, LED10, LED11, LED12, LED13, LED14, LED15 and LED16 power supply at contact J3 and J4 place output DC.When the 127V power cut-off, light to LED15, LED13, LED11, LED9, LED8, LED6, LED4 and LED2 power supply by J8 and J7 after boosting by the DC power supply that previous charging back is standby, other led light source extinguishes, the power of whole light fixture reduces half automatically, one times of emergency lighting time lengthening.
