Abstract
The invention provides an automatic-control type light-emitting diode (LED) power supply which mainly solves the problem that work of a power supply in the prior art cannot be adjusted to be suitable for the environment to cause that the power supply is prone to be damaged. The automatic-control type LED power supply comprises a circuit board, a power supply box body and a power supply box cover, wherein the circuit board is fixedly arranged in the power supply box body. The power supply box body is in a U shape or an L shape and comprises a power supply box body lateral wall and a power supply box body bottom plate, the circuit board is fixedly arranged on the power supply box body bottom plate, and a control device for cutting off the power supply or reducing power supply power when power supply temperature is too high or humidity of environment where the power supply is arranged is too high is positioned on the circuit board. The control device additionally arranged in the automatic-control type LED power supply is used for cutting off the power supply or reducing power supply power when power supply temperature or humidity is too high so as to prevent the power supply from being damaged and prolong service life of the power supply.
Description
Technical field
The present invention relates to the LED lighting field, especially relate to a kind of automatic control type LED power supply.
Background technology
Desirable LED adopts constant voltage, constant current.But the cost of driver increases.Every kind of type of drive all has excellent, shortcoming in fact, according to requirement, the application scenario of LED product, and reasonable selection LED type of drive, accurately the design driven power supply becomes key.Although LED efficient than ordinary light source aspect energy-conservation is high, but LED light source but can not can directly use utility grid voltage as general light source, it must be furnished with the specialized voltages conversion equipment, provide and to satisfy the specified voltage and current of LED, just can make the LED normal operation, also with regard to the special source of so-called LED.
Existing LED power supply does not all arrange control device, causes like this power supply, can't in time cut off power supply, or reduce power when too high in excess Temperature or humidity, and power supply is damaged.
Summary of the invention
The invention provides a kind of automatic control type LED power supply, mainly solved prior art and can't do the adjustment that is adapted to environment to power work, cause the flimsy problem of power supply.
Concrete technical solution of the present invention is as follows:
A kind of automatic control type LED power supply, comprise wiring board, power supply box body and power supply lid, above-mentioned wiring board is fixedly installed in the power supply box body, and described power supply box body is " U " type or " L " type, comprise power pack body sidewall and power supply box plate, wiring board is fixedly installed on the power supply box plate; Be provided with on described wiring board for when the power supply excess Temperature, or power supply ambient humidity of living in is used for when higher cutting off the electricity supply or reduces the control device of power, control device is electrically connected to wiring board.
Control device comprises temperature sensor and controller, and the said temperature sensor is fixedly installed on the power pack body sidewall, regulates the power output of power supply or closes after the temperature of controller reception temperature sensor or moisture signal.
Control device comprises temperature sensor and on-off controller, and the said temperature sensor is fixedly installed on the power pack body sidewall, and the measurement temperature of temperature sensor or humidity is during higher than the thresholding of on-off controller, the direct powered-down of on-off controller.
The invention has the advantages that:
The present invention has set up control device in automatic control type LED power supply, this control device is used for, reducing power or power supply being cut off when too high in excess Temperature or humidity, has avoided the damage of power supply, has extended the service life of power supply.
Description of drawings
Fig. 1 is the structural representation of automatic control type LED power supply of the present invention.
Wherein: the 4-control device; 5-power supply box body.
The specific embodiment
A kind of automatic control type LED power supply, comprise wiring board, power supply box body and power supply lid, above-mentioned wiring board is fixedly installed in the power supply box body, and described power supply box body is " U " type or " L " type, comprise power pack body sidewall and power supply box plate, wiring board is fixedly installed on the power supply box plate; Be provided with on described wiring board for when the power supply excess Temperature, or power supply ambient humidity of living in is used for when higher cutting off the electricity supply or reduces the control device of power, control device is electrically connected to wiring board.
Control device comprises temperature sensor and controller, and the said temperature sensor is fixedly installed on the power pack body sidewall, regulates the power output of power supply or closes after the temperature of controller reception temperature sensor or moisture signal.
Control device comprises temperature sensor and on-off controller, and the said temperature sensor is fixedly installed on the power pack body sidewall, and the measurement temperature of temperature sensor or humidity is during higher than the thresholding of on-off controller, the direct powered-down of on-off controller.
