Abstract
The utility model provides a power vacancy self-controlling light emitting diode (LED) power supply and mainly solves the problems that an existing power tube has poor heat dispersion and large pin stress; an existing power vacancy self-controlling LED power supply has poor heat dispersion and can not operate in high-temperature and high-humidity environment ; and in the prior art, the power supply can not be adjusted to adapt to environment when the power supply operates so that the power supply is prone to being damaged. The power vacancy self-controlling LED power supply comprises a circuit board, a power supply box body and a power supply box cover. The power tube is electrically connected with the circuit board, and the power tube is fixedly disposed on a sidewall of the power supply box body. A vacancy unit is independently and perpendicularly disposed on the circuit board, and the circuit board is provided with a control device. The power tube is disposed on the sidewall of the power supply box body, so not only the problem of heat dispersion but also the problem of the pin stress is resolved. An installation method that the vacancy unit is perpendicularly disposed on the circuit board ensures that the heat dispersion is easy; and due to the arrangement of the control device, the power supply is prevented from being damaged, and service life of the power supply is prolonged.
Description
Technical field
The present invention relates to the LED lighting field, especially relate to the vacant automatic control type LED of a kind of power power supply.
Background technology
The power tube of existing LED power supply generally is set directly on the wiring board, causes heat comparatively concentrated like this, is unfavorable for heat radiation; In order to address this problem, the technical staff adopts the set-up mode perpendicular to wiring board, but has increased the stress of pin like this, and long-term the use is prone to cause potential safety hazard.
The vacant unit of existing LED power supply is generally positioned on the wiring board, and this set-up mode is unfavorable for heat radiation, is not suitable for the operate as normal of hot and humid environment.
Existing LED power supply all is not provided with control device, when causing power supply so too high or humidity is too high in temperature, can't in time cut off power supply, or reduce power, and power supply is damaged.
Summary of the invention
The present invention provides the vacant automatic control type LED of a kind of power power supply, has solved mainly that existing power tube heat dispersion is poor, pin stress is big; The existing vacant automatic control type LED of power power supply heat sinking poor performance is worked in the hot and humid environment again; Prior art can't be done the adjustment that is adapted to environment to power work, causes the flimsy problem of power supply.
Concrete technical solution of the present invention is following:
The vacant automatic control type LED of a kind of power power supply; Comprise wiring board, power supply box body and power supply lid; Above-mentioned wiring board is fixedly set in the power supply box body; Above-mentioned power supply box body is " U " type or " L " type, comprises power pack body sidewall and power supply box plate, and wiring board is fixedly set on the power supply box plate; Above-mentioned power tube is electrically connected with wiring board, and power tube is fixedly set on the power pack body sidewall; Above-mentioned vacant unit independently is vertically installed on the wiring board, and the operating temperature of vacant unit is-40 ℃～100 ℃; Above-mentioned wiring board is provided with and is used for when the power supply temperature is too high, or power supply ambient humidity of living in is used to when higher to cut off the electricity supply or reduces the control device of power, and control device is electrically connected with wiring board.
Above-mentioned control device comprises temperature sensor and controller, and the said temperature sensor is fixedly set on the power pack body sidewall, and controller receives to be regulated the power output of power supply behind temperature or the moisture signal of temperature sensor or close.
Above-mentioned control device comprises temperature sensor and on-off controller, and the said temperature sensor is fixedly set on the power pack body sidewall, during thresholding that the measurement temperature of temperature sensor or humidity are higher than on-off controller, and the direct powered-down of on-off controller.
The invention has the advantages that:
1, the present invention adopts power tube is arranged on the power pack body sidewall; And then pin is connected with wiring board, because the power pack body sidewall is that heat sink material is processed, and power tube is completely fixed and be fitted on the power pack body sidewall; Promptly solve heat dissipation problem, solved the stress problem of pin again.
2, the present invention takes mounting means is in the circuit board erect in vacant unit, is provided with like this to be prone to heat radiation, can carry out independent replacing to vacant unit, is applicable to hot and humid environment, can be at-40 ℃～100 ℃, and operate as normal in 90% humidity environment; When humidity in the power supply was big, dew can flow down along the wiring board of erectting; Simultaneously, erect setting and can form the air channel, be beneficial to airflow and take away heat, further improved radiating effect.
3, the present invention has set up control device in the vacant automatic control type LED of power power supply, when this control device is used in temperature that too high or humidity is too high, reduces power or power supply is cut off, and has avoided the damage of power supply, has prolonged the service life of power supply.
