Abstract
The utility model relates to the field of daily life, especially to an adjustable driving power supply for a straight lamp, which comprises an adjustable potentiometer. The adjustable potentiometer is connected with a driving power supply for an LED (Light-Emitting Diode) straight lamp, and the driving power supply for the LED straight lamp is connected with an LED load. The adjustable potentiometer is also connected with an MSP1132 power supply managing chip. The adjustable driving power supply for the straight lamp has the advantages that the adjustable driving power supply is universal for power supplies of 9-18W straight lamps; production is convenient, and unnecessary thread-changing links are omitted; precision of output current can be flexibly adjusted according to practical requirements; and resistor and labor cost required for current precision adjustment is saved.
Description
Technical field
The utility model relates to daily life field, relates in particular to a kind of adjustable driving power for straight lamp.
Background technology
Traditional fluorescent lamp comprises lamp bracket, reflection shield, starter, rectifier etc., and device is more relatively, installs to be difficult for, and still traditional fluorescent lamp adjusting power is regulated by voltage, but not directly adjusts in power output, therefore wastes energy.
The utility model content
The purpose of utility model: for a kind of adjustable, energy-conservation adjustable driving power is provided.
In order to reach as above purpose, the utility model is taked following technical scheme:
A kind of adjustable driving power for straight lamp is characterized in that, comprises adjustable potentiometer, and described adjustable potentiometer connects LED straight lamp driving power, and described LED straight lamp driving power connects the LED load.
The further technical scheme of the utility model is that described LED straight lamp driving power also connects transformer.
The further technical scheme of the utility model is that described adjustable potentiometer connects the MSP1132 power management chip.
The further technical scheme of the utility model is that described straight lamp is the LED straight lamp.
The further technical scheme of the utility model is that described adjustable potentiometer connects the LED straight lamp driving power of an above fluorescent tube.
Adopt as above the utility model of technical scheme, have following beneficial effect:
1, realizes that 9--18W straight lamp power supply is general; 2, convenient tissue is produced, and deducts unnecessary thread-changing link; 3, the output current precision can be by the required flexible adjustment of reality; 4, save the adjustment required resistance of current precision and labour cost.
Description of drawings
In order to further specify the utility model, further describe below in conjunction with accompanying drawing:
Fig. 1 is the adjustable driving power principle schematic of many power of LED straight lamp section of utility model; Fig. 2 is the structural representation of utility model.
Embodiment
