Description
Technical field
The present utility model relates to the low-power LED illuminating lamp device, especially a kind of illuminating lamp that is applicable to that solar powered low-power LED constitutes.
Background technology
Present known low-power LED illuminating lamp has three kinds of common practice, and first kind of way is that each LED luminous tube or the series connection of several LED luminous tube are next luminous by a constant-current drive circuit driving, and the whole LED lamp is powered by a dc source.Second kind of way is that each LED luminous tube or the series connection of several luminous tube come luminous by a resistance current limliting.The third way is that each the LED luminous tube with parallel connection links together, and drives with a constant-current source then to make the LED luminous tube luminous.
The problem that the LED illuminating lamp of first kind of way exists is: because except the LED luminous tube, also need a large amount of drive circuits, so complex structure is bulky, and the cost height.Therefore having limited the LED illuminating lamp of this structure uses.The problem that the LED illuminating lamp of second kind of way exists is: because of solar powered voltage is unstable, the supply current of LED luminous tube is changed, thereby cause the LED lamp scintillation to occur.The shortcoming of the third way is in case a string LED luminous tube opens circuit or a few string LED luminous tube opens circuit, and will cause the electric current of other LED luminous tube string in parallel to increase, thereby not reduce the life-span of LED luminous tube, even can burn out the LED luminous tube.
Summary of the invention
For overcoming the deficiency of existing low-power LED illuminating lamp, the utility model provides a kind of low-power LED illuminating lamp that is applicable to unstable DC power supply.This low-power LED illuminating lamp is not only simple in structure, and cost is low,
The technical scheme that its technical problem that solves the utility model adopts is: housing is made up of three kinds of circuit boards.First kind of circuit board is provided with mu balanced circuit, and the input and the feeder ear of mu balanced circuit join, and the output of mu balanced circuit connects the LED luminous tube.When solar powered voltage change, mu balanced circuit output constant voltage circuit has guaranteed the stable of LED luminous tube supply current.Second kind of circuit board is 18 luminous tube sheets of bar-shaped LED, is connected in series by 1 resistance and 4 LED luminous tubes on the luminous tube sheet of each bar-shaped LED and forms.The third circuit board is to be connected in parallel by two groups of LED luminous tubes to constitute, and each group LED luminous tube is to be connected in series by 1 resistance and 4 LED luminous tubes to form.
Above-mentioned described LED luminous tube is direct insertion LED luminous tube or surface welded LED luminous tube.
Above-mentioned described resistance is surface-mount type resistance, and the electric current that assurance LED luminous tube passes through is in a stable interval.
Above-mentioned described circuit board is a pcb board, and solder mask is white, to guarantee the brightness of LED lamp.
The beneficial effects of the utility model are: when constant luminance illumination was provided, the housing of illuminating lamp only was made up of pcb board, had simplified the structure of installing, and had reduced cost, had guaranteed the heat radiation of LED luminous tube simultaneously, director the life-span of LED luminous tube.
The utility model compares with first kind of way: reduced a large amount of drive circuits that a large amount of LED illuminating lamps in the past exist, reduced the LED illuminating lamp control circuit, reduced cost.
The utility model is compared with second kind of way: guaranteed the constant luminance of LED illuminating lamp, prolonged the service life of LED luminous tube.
Below in conjunction with drawings and Examples the utility model is further described.
