Abstract

The utility model provides a vacant integrated light-emitting diode (LED) power supply which mainly solves problems that the existing vacant integrated LED power supply is poor in radiating performance and not capable of working in high-temperature and high-humidity environments and heat conduction performance and strength are poor in the prior art. The vacant integrated LED power supply comprises a circuit board, a power supply box body and a power supply box cover, wherein a vacant unit is independently and vertically arranged on the circuit board, one side of a baseboard of the power supply box body far away from the circuit board is completely attached to an installed portion, and the baseboard of the power supply box body and the lateral wall of the power supply box body form an integrally formed insulation heat conduction box. The installation mode that the vacant unit is vertically arranged on the circuit board is adopted so that the vacant unit can be replaced independently, the LED power supply is suitable for high-temperature and high-humidity environments, an air flue favorable for airflow circulating and heat taking away can be formed through vertical arrangement of the vacant unit, and the radiating effect is further improved. The power supply box body is an integrated part and is uniform in radiating and high in strength. Simultaneously, the back of the box body is processed so that the box body is led to be tightly contacted with an installed part and heat conduction is benefited.

Description

Vacant one-piece type LED power supply

Technical field

The present invention relates to the LED lighting field, especially relate to a kind of vacant one-piece type LED power supply.

Background technology

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.

The existing power supply box body is generally the split part, cause the intensity of power supply box body lower like this, and the each several part heat dispersion is inconsistent, is unfavorable for heat radiation; Simultaneously, does not generally handle existing power supply box body bottom, and it is not tight to cause power supply bottom and mounted piece to be fitted, and is unfavorable for the heat conduction.

Summary of the invention

The present invention provides a kind of vacant one-piece type LED power supply, has mainly solved existing vacant one-piece type LED power supply heat sinking poor performance, works in the hot and humid environment again; The problem that prior art heat-conductive characteristic and intensity are relatively poor.

Concrete technical solution of the present invention is following:

A kind of vacant one-piece type LED 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, and above-mentioned power supply box body is " U " type or " L " type; Comprise power pack body sidewall and power supply box plate, wiring board is fixedly set on the power supply box plate; Above-mentioned vacant unit independently is vertically installed on the wiring board, and the operating temperature of vacant unit is-40 ℃～100 ℃; Above-mentioned power supply box plate away from circuit board one side be mounted the position and fit the insulating heat-conductive box that power supply box plate and power pack body sidewall are formed in one fully.

The invention has the advantages that:

1, 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.

2, power supply box body provided by the invention is an integral piece, and heat radiation is even, and intensity is high; Simultaneously, the box body back is handled, make its with mounted piece between contact closely, be beneficial to the heat conduction.
