Description
Affiliated technical field
The utility model belongs to technical field of semiconductor illumination, relate to a kind of mine laneway continuous illumination light fixture, its product is suitable for mine laneway (tunnel), airport, station, hotel, market place builet below the ground, and underground parking etc. need safety, occasion reliable, continuous illumination to use.
Background technology
At present mine laneway all adopts incandescent lamp to make lighting usually, the advantage of this illuminating lamp be cheap, colour temperature is lower, but since in the tunnel continuous lighting time very long, the life-span of incandescent lamp is but relatively very short, needs often replacing; And the power consumption of incandescent lamp is bigger, and annual electricity charge spending and maintenance cost are also very surprising; In addition, when power interruptions, the tunnel intraoral illumination can not guarantee that if adopt the stand-by power supply power supply, because the light fixture power demand is bigger, stand-by power supply also must possess bigger power.
In recent years, along with the fast development of semiconductor lighting technology, white light emitting diode WLED (while light emitting diode) has been applied to mine-use cap lamp.Because this semi-conductor lighting lamp power consumption is minimum, the capacity of required storage battery is very little, and the weight of mine lamp is reduced to about 0.4Kg from about 3Kg, and illumination rises to 1400Lx from 800Lx, the life-span of bulb also rose to more than 30000 hour from more than 1000 hours, realized the technological revolution of mine lamp.For this novel illumination lamp being used for the mine laneway illumination, must increase the power and the irradiating angle of semi-conductor lighting lamp.Produce in batches than the large-power semiconductor illuminating lamp at present, and have producer to begin to select for use high-power WLED mine main tunnel illuminating lamp.But therefore prior art products also has big difficulty because cost is higher, and irradiating angle is less, and when power supply interrupts, can not guarantee emergency lighting aspect applying.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and then a kind of rational in infrastructure, superior performance, long service life is provided and can guarantees the continuous illumination mine laneway WLED lamp of emergency lighting.
The technical solution that adopts is so for achieving the above object: the continuous illumination mine laneway WLED lamp that is provided is by the ac/dc power circuit, the DC/DC converter, signal feedback circuit, the main illuminating lamp battle array of using, rectification circuit, battery charge control circuit and standby lighting lamp are formed, wherein: the output of ac/dc power circuit connects with the voltage input end of DC/DC converter, one road output end voltage of DC/DC converter is added in main with on the illuminating lamp battle array input, the input of signal feedback circuit and main sensitization with the illuminating lamp battle array, temperature-sensitive sampled signal output connects, and the output of signal feedback circuit is attached to the light modulation of DC/DC converter, the temperature adjustment control input end; Another road output end voltage of DC/DC converter is successively through being added in behind rectification circuit and the battery charge control circuit on the standby lighting lamp control input end.In the real work, interchange or DC input voitage all can be by ac/dc power circuit input DC/DC converters, the output current of this converter is controlled by feedback signal, sample by sensor devices and temperature sensing device respectively by the main ambient humidity, light and temperature that WLED lamp array is formed with the illuminating lamp battle array, luminosity sampling signal and temperature sampling signal are admitted to the DC/DC converter, change the output current of constant-current source, may command master uses the ambient humidity, light and temperature of illuminating lamp battle array; During the power supply normal power supply, battery charge control circuit is in charged state, the storage battery floating charge of standby lighting lamp at ordinary times, power WLED lamp is powered by external power supply, during the improper interruption of power supply, the standby lighting lamp can be worked on by storage battery power supply, satisfies the requirement of tunnel lamp continuous illumination.
In order to overcome the problem that present power WLED tunnel lamp exists, it is main with illuminating lamp battle array (main light source) that the utility model adopts cheap small-power super brightness array to form, though the irradiating angle of single WLED is limited, after but many WLED formed array, illumination intensity of light source and irradiating angle all can satisfy the requirement of mine laneway illumination; WLED matrix lamp lamp adopts contour structures and the identical bulb of ordinary incandescent lamp commonly used, and can directly be powered by the 48V-450V power of alterating and direct current.Therefore can directly substitute incandescent lamp bulb commonly used.Pack in the Explosion-proof globe, can satisfy the mine laneway lighting requirement.The power of WLED lamp is 5W, can replace the 40W incandescent lamp, thereby can save the electricity charge of 80%-90%, makes bigger contribution for making up energy-efficient society.In addition.In order to realize continuous illumination, the volume of packing in the lamp of tunnel is very little, the ferric phosphate lithium cell that security performance is very high and a power WLED lamp.During the power supply normal power supply, the lithium battery floating charge, power WLED lamp is powered by external power supply, after the power interruptions, lithium battery is given the power supply of power WLED lamp, because the power consumption of this lamp is very little and supply power voltage is very low, a lithium battery can be powered more than 10 hours, very long if ask for perfection with lighting hours, can increase the capacity of lithium battery.If the illumination requirement to standby lighting is lower, can match lower-powered standby WLED illuminating lamp, can satisfy the requirement of emergent long-time illumination.
