Abstract
The utility model provides a layout structure of a driving power supply of an LED street lamp. An EMI circuit, a PFC circuit, an LLC circuit and a constant-current control circuit are distributed on a PCB. The PCB is a one-face board. The EMI circuit, the PFC circuit, the LLC circuit and the constant-current control circuit are arranged from left to right in sequence. A linear cooling fin is transversely arranged between an EMI circuit area and a PFC circuit area. The linear cooling fin is located on the edge of the PCB. An L-shaped cooling fin is arranged between the PFC circuit area and an LLC circuit area. A linear cooling fin is longitudinally arranged in a constant-current circuit area. One end of the linear cooling fin extends into the constant-current control circuit area. The other end of the linear cooling fin extends to the edge of the PCB. By the adoption of the circuit layout and the cooling fin layout, the overall size of the driving power supply can be reduced, the cooling effect of a cooling device is optimized, the overall performance of the circuits is effectively improved, the cooling efficiency is improved, and the reliability of the power supply is improved.
Description
Technical field
The utility model belongs to LED technical field, is specifically related to a kind of layout structure of LED streetlamp driving power supply.
Background technology
In the market, middle high-powered LED lamp series of products all need corresponding special driving power, the size of power supply tends to be subject to the restriction of product structure and has nothing in common with each other, the structure of some power supply is very unreasonable from profile to internal structure, do not reach instructions for use, there will be the water inlet of inner hot-spot or product and affect the quality of product.The phenomenons such as radiator structure layout is unreasonable because existing LED driving power exists that foregoing circuit layout is unreasonable, on plate, therefore directly cause circuit performance and power quality to decline to some extent, even may have hiding use potential safety hazard.Once if there are the problems referred to above, can cause entire block to change, thereby bring huge maintenance cost.
Utility model content
For the problems referred to above, the utility model provides a kind of layout structure of LED streetlamp driving power supply.
The technical solution of the utility model: a kind of layout structure of LED streetlamp driving power supply, on pcb board, be distributed with EMI circuit, pfc circuit, LLC circuit and constant-current control circuit, pcb board adopts single sided board, and described EMI circuit, pfc circuit, LLC circuit and constant-current control circuit are arranged from left to right according to said sequence; Between EMI circuit region and pfc circuit region, be laterally provided with linear pattern fin, linear pattern fin is positioned at the edge of pcb board; Between pfc circuit region and LLC circuit region, be provided with L-type fin (2), a right-angle side of L-type fin (2) is across between pfc circuit region and LLC circuit region, and another right-angle side of L-type fin (2) stretches to pcb board edge in LLC circuit region; In constant-current control circuit region, be longitudinally provided with linear pattern fin, one end of linear pattern fin puts in constant-current control circuit region, and the other end of linear pattern fin reaches pcb board edge.
The beneficial effects of the utility model: the circuit layout and the fin layout that adopt the design, can effectively reduce driving power overall dimensions, reach the radiating effect of optimizing radiating element, and the reliability that effectively promotes circuit overall performance, improves radiating efficiency and improve power supply.
