As shown in fig. 1, in the embodiment of the ultralow temperature starting device for the lamp of the present application, the ultralow temperature starting device mainly includes a heating circuit 10 and a lamp main control circuit 20, and the lamp main control circuit 20 includes a switching power supply, a lamp main control board, an LED driver board, and an LED lamp panel. When the lamp is powered on in an extremely low temperature environment (below minus 40 ℃), the switching power supply cannot be normally started because the ambient temperature is too low, so that the lamp cannot be normally started. Therefore, a heating circuit 10 connected in parallel with the lamp main control circuit 20 is provided, and the heating circuit comprises a heating unit and a control unit, wherein the control unit is electrically connected with the heating unit, the lamp main control board is connected with the control unit, and the control unit is used for controlling the on-off of the heating unit.
As shown in fig. 2, the heating unit mainly includes a transformer T1 and a heating resistor R4. Specifically, a transformer T1 is connected in parallel with the switching power supply at the power supply input end, and a relay K1 and a heating resistor R4 connected in parallel are connected to the transformer. Because the transformer T1 is not affected by the ambient temperature in operation, the switch power supply can start normally even at very low temperature, therefore, the commercial power can electrify the heating resistor R4 through the transformer T1 and the normally closed common contact K11 of the relay K1, thereby heating the internal environment of the lamp, raising the internal temperature of the lamp and meeting the starting condition of the switch power supply. In the present embodiment, three heating resistors R4 connected in parallel are used for heating, but it is needless to say that a plurality of resistors may be connected in parallel or in series as the case may be, and other elements capable of heating the surrounding environment by electric heating may be used instead of the resistors for heating.
The control unit mainly comprises a relay K1, a triode Q1, a diode D2 and resistors R1, R2 and R3, and is connected to the lamp main control board. The emitting electrode of the triode Q1 is connected with a lamp main control board, the collecting electrode is connected with the diode D2, the relay K1 and the resistor R1, and the resistors R2 and R3 are connected with the base electrode of the triode Q1. When the ambient temperature of the switching power supply rises to reach the starting temperature of the switching power supply, the switching power supply is automatically started, the switching power supply supplies power to the lamp main control board, and then the lamp main control board CPU judges the internal temperature of the lamp by detecting the thermistor on the lamp main control board. When the internal temperature of the lamp is higher than-20 ℃, the normal working condition of the lamp is achieved, after the lamp starts to work, the lamp main control board enables the relay K1 to stop working through the triode Q1, namely, the common contact K11 of the relay is switched from a closed position to a normally open position, and the heating resistor R4 is powered off and stops heating. The lamp can maintain the operation of the lamp in an extremely low environment through the heat emitted by the lamp during the operation.
The diode D2 in the control unit is optional and is provided to eliminate the possibility of damaging the transistor Q1 by the electromotive force of the coil of the relay K1 when the relay K1 is switched from the on state to the off state.
Preferably, a fan connected with the lamp main control board may be further provided, and when the switching power supply is started, but the ambient temperature is still lower than the normal starting temperature of the lamp (lower than-30 ℃), at this time, the relay is still in a normally closed state, the heating resistor R4 is still heating continuously, and at this time, the lamp main control board controls the fan to start working. The fan blows to accelerate air circulation in the lamp, so that heat emitted by the heating resistor R4 can rapidly and uniformly heat the interior of the lamp body. When the lamp is normally started, the fan is controlled by the lamp main control board to stop working, and then the lamp can work in an extremely low environment through heat emitted by the lamp.
Certainly, the fan can also be connected in series with the heating resistor R4, so that the fan and the heating resistor R4 can be started and closed simultaneously, the heat flow in the lamp can be accelerated, and the lamp can work normally and quickly.
Preferably, the heating resistor R4 is arranged around the switching power supply, so that the temperature rise of the environment around the switching power supply can be more facilitated.
The utility model provides a lamps and lanterns ultra-low temperature starting drive, simple high-efficient can make lamps and lanterns rapid heating lamps and lanterns inside temperature under the environment of ultra-low temperature rapidly to lamps and lanterns can normally start the work, both can be used in the regional winter view lamps and lanterns of high latitude on, also can use on other lamps and lanterns.
The above embodiments are intended to be illustrative, and should not be construed as limiting the scope of the invention, and the technical solutions, objects and effects of the present invention are described in full herein.
The above examples are not intended to be exhaustive list of the present invention, and there may be many other embodiments not listed. Any replacement and improvement made on the basis of not violating the conception of the utility model belong to the protection scope of the utility model.
