Abstract
The utility model relates to the technical field of lighting, in particular to an over-temperature protection light-emitting diode (LED) mining lamp. The over-temperature protection LED mining lamp is characterized in that a heat dissipation seat is provided with a cooling fan, a temperature sensor is arranged on the heat dissipation seat near the bottom of an LED lamp substrate and connected with an over-temperature outage module, and the over-temperature outage module is connected with LED lamps on the LED lamp substrate and controls the LED lamps. The heat dissipation seat is provided with the cooling fan so that convection of air on the heat dissipation seat is accelerated and heat is dissipated quickly, and cost of a heat dissipation seat with a large size is reduced. In addition, when the cooling fan stops rotating because of breakdowns, the temperature sensor arranged on the heat dissipation seat can transmit information of temperature to the over-temperature outage module, and the over-temperature outage module enables the LED lamps to be turned off and stop working if the temperature exceeds a set temperature so that the problem that a mining lamp is damaged and scrapped because of over-temperature is avoided and fire accidents caused by poor heat dissipation of the mining lamp can be avoided effectively.
Description
Technical field:

Background technology:
LED light lamp (LED lamp) is because power saving; Have energy-conservation, long advantages such as (life-span are more than 100,000 hours in theory) of life-span, but ought be in use at powerful bulkhead lamp capable, the heat that the LED lamp sends is also bigger; When causing great power LED equipment to have under higher operating temperature, move; Can cause service life of the LED lamp grain of bulkhead lamp capable to reduce greatly even damage and scrap, thereby need to dispose the bigger radiating equipment of volume, waste material for better heat radiation; Also has a kind of situation at present; Be that fan heat radiation is set on the radiating seat of bulkhead lamp capable, yet break down to work the time when fan, cause the LED lamp grain of bulkhead lamp capable to dispel the heat insufficient; Cause the damage of bulkhead lamp capable to be scrapped easily, the initiation fire accident is not freely understood in heat radiation under the serious situation.
The utility model content:
The purpose of the utility model is exactly the light emitting diode bulkhead lamp capable that a kind of overtemperature protection that overcomes the above problems is provided to the deficiency of the lamp grain heat radiation existence of prior art bulkhead lamp capable.
To achieve these goals, the technical scheme of the utility model employing is:
The light emitting diode bulkhead lamp capable of overtemperature protection; Said bulkhead lamp capable successively by lamp holder, radiating seat, the lamp grain substrate of LED lamp grain is set and is covered with the translucent cover of putting on the lamp grain substrate, supply unit is set in the lamp holder, on the said radiating seat radiator fan is set; Radiating seat is provided with temperature sensor near the bottom of lamp grain substrate; Overheated power-off modular also is set in the said lamp holder, and temperature sensor connects overheated power-off modular, and overheated power-off modular connects the LED lamp grain on the control lamp grain substrate.
Between said lamp holder and radiator fan thermal baffle is set, thermal baffle is connected through joint pin with radiator fan.
Heat-insulating base also is set between said lamp holder and thermal baffle, and heat-insulating base is provided with the hollow out louvre of hollow.
Said radiator fan top is covered with the cover of upholstery to lamp grain orientation substrate.
The utility model beneficial effect is: the light emitting diode bulkhead lamp capable of the utility model overtemperature protection; The light emitting diode bulkhead lamp capable of overtemperature protection; Said bulkhead lamp capable successively by lamp holder, radiating seat, the lamp grain substrate of LED lamp grain is set and is covered with the translucent cover of putting on the lamp grain substrate, supply unit is set in the lamp holder, on the said radiating seat radiator fan is set; Radiating seat is provided with temperature sensor near the bottom of lamp grain substrate; Overheated power-off modular also is set in the said lamp holder, and temperature sensor connects overheated power-off modular, and overheated power-off modular connects the LED lamp grain on the control lamp grain substrate; When bulkhead lamp capable is worked, because radiator fan is set, can quicken the convection current of air on the radiating seat on radiating seat, make the heat that LED lamp grain produced is set on the lamp grain substrate in time conducts through radiating seat, reduce and use larger volume radiating seat cost; When stopping operating as if fan failure in addition; The temperature sensor that is arranged on the radiating seat is transferred to overheated power-off modular with temperature information; When surpassing the temperature of setting, overheated power-off modular makes the outage of LED lamp grain, quits work; Avoid the too high damage of temperature of bulkhead lamp capable to scrap, can also prevent effectively that bulkhead lamp capable heat radiation freely do not understand the initiation fire accident.
