Abstract
The utility model discloses an LED lamp power supply structure which can prolong the service life of an LED, and can reduce the installation size and lower the cost. The improved LED lamp power supply structure is composed of a driving power supply module, a high voltage constant current module and an LED lamp which are in series connected sequentially. The driving power supply module and the high voltage constant current module are combined into an independent integral module and are further connected in series with an independent LED lamp. The structure reduces the installation size and lowers the cost greatly, and the constant current module is separated from the lamp, which is beneficial for dissipating heat and prolonging the service life of the LED lamp and the constant current module. The output voltage can be designed between DC60V and 400V, accordingly the LED can be directly connected in series, the output voltage is high, the efficiency is high, the amount of multi-path output constant current modules can be greatly reduced by more than one time, and the cost is lowered by 20% to 30%.
Description
Technical field
The utility model relates to a kind of electric power-feeding structure of LED light fixture.
Background technology
The electric power-feeding structure of the LED lamp of traditional mode mainly contains two kinds of forms, and first kind is: driving power module, constant flow module are connected with LED light fixture three, and this form installation dimension is big, the cost height; Second kind is: the integral body that driving power module and constant current and light fixture constitute is together in series, and under this form, constant flow module is unfavorable for heat radiation with combining of light fixture, has shortened the useful life of LED lamp and power supply.The design of traditional mode is below DC60V, and LED connection in series-parallel number increases, the cost height, and output voltage is low, and efficient is low, is unfavorable for energy-conservation.
The utility model content
At the problems referred to above, the utility model aims to provide and a kind ofly can prolong LED useful life, and can dwindle the LED lamp electric power-feeding structure that installation dimension reduces cost.
For realizing this technical purpose, a kind of improved LED lamp electric power-feeding structure of the present utility model, be composed in series in proper order by driving power module, high voltage and constant current module and LED light fixture, described driving power module and high voltage and constant current module are combined into an independent integral module and connect with LED light fixture independently.
Adopt the advantage of this structure to be: constant pressure source combines with constant current, has reduced the size of installing, and cost reduces greatly; Constant flow module separates with light fixture, helps heat radiation, prolongs the useful life of LED lamp and constant flow module; Output voltage can design at DC60V～400V, and LED directly connects like this, the output voltage height, and the efficient height can reduce more than the multichannel output constant flow module quantity to one times greatly, and cost reduces by 20%～30%.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
As shown in Figure 1, a kind of improved LED lamp electric power-feeding structure of the present utility model, be composed in series in proper order by driving power module, high voltage and constant current module and LED light fixture, described driving power module and high voltage and constant current module are combined into an independent integral module and connect with LED light fixture independently.
Adopt the advantage of this structure to be: the combination of constant pressure source and constant current, reduced the size of installing, cost reduces greatly; Constant flow module separates with light fixture, is conducive to heat radiation, prolongs the service life of LED lamp and constant flow module; Output voltage can design at DC60V～400V, and LED directly connects like this, the output voltage height, and the efficient height can reduce more than the multichannel output constant current module number to a times cost 20%～30% greatly.
