Abstract
The utility model discloses a circuit structure in low pressure L ED lamp area, including a plurality of parallel connection L ED series unit, each L ED series unit comprises a plurality of L ED lamp pearls and resistance series connection, the rated operating voltage of L ED lamp pearl is 3V, L ED series unit's rated operating voltage is 24V, L ED series unit is by eight L ED and one the resistance series connection is constituteed.
Description
Technical Field
The utility model relates to an L ED illumination lamps and lanterns specifically disclose a circuit structure in low pressure L ED lamp area.
Background
The existing low-voltage L ED lamp strip comprises a sheath, a circuit board is wrapped in the sheath, a plurality of L ED lamp beads and resistors are welded on the circuit board, a low-voltage L ED lamp strip with the working voltage of 24V is taken as an example, the circuit structure of the low-voltage L ED lamp strip is shown in figure 1, the rated working voltage of each L ED lamp bead is 3V, 6L ED lamps and 2 resistors are connected in series to form a series unit 10, the series units 10 are connected in parallel, the working voltage of each series unit 10 is 24V, the resistors consume power but cannot emit light, the circuit has the effect of restraining current surge and protecting L ED from being broken down by current surge, and as the series unit 10 is formed by connecting 6L ED lamps and 2 resistors in series in the prior art, the voltage loaded on each L ED lamp bead is higher, the L ED light effect is reduced, the resistors are more used, and the light effect of the lamp strip is further reduced.
SUMMERY OF THE UTILITY MODEL
Therefore, a need exists for providing a low-voltage L ED lamp strip circuit structure with high luminous efficiency and low cost, which aims at the problems of the prior art.
In order to solve the prior art problem, the utility model discloses a low pressure L ED lamp area circuit structure, including a plurality of parallel connection L ED series unit, each L ED series unit comprises a plurality of L ED lamp pearls and resistance series connection, L ED lamp pearl's rated operating voltage is 3V, L ED series unit's rated operating voltage is 24V, L ED series unit is by eight L ED and one the resistance series connection is constituteed.
The beneficial effects of the utility model are that, the utility model discloses because L ED tandem unit includes eight L ED lamp pearls, compare with prior art, L ED lamp pearl is more in quantity to the voltage of loading to each L ED lamp pearl is littleer, and the light efficiency of single L ED lamp pearl is higher, because only set up a resistance in the L ED tandem unit again, compare with prior art, resistance still less, thereby the power of consumption is also littleer, and L ED lamp area whole light efficiency is higher.
Drawings
Fig. 1 is a schematic diagram of a circuit structure of a conventional low-voltage L ED light strip.
Fig. 2 is a schematic diagram of the circuit structure of the present invention.
Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
Referring to fig. 2, a circuit structure of a low-voltage L ED lamp strip includes positive and negative electrode circuits P/N extending along a length direction of the lamp strip, a plurality of L ED series units 10 are disposed between the positive and negative electrode circuits P/N, positive and negative electrodes of the L ED series units 10 are respectively connected to the positive and negative electrode circuits P/N, the L ED series units 10 are formed by connecting eight L ED lamp beads 1 and one resistor 2 in series, a rated operating voltage of the L ED lamp bead 1 is 3V, and a rated operating voltage of the L ED series unit 10 is 24V.
The utility model discloses because L ED series unit 10 includes eight L ED lamp pearls 1, compare with prior art, L ED lamp pearl 1 is more in quantity to the voltage of loading to each L ED lamp pearl is littleer, and the light efficiency of single L ED lamp pearl is higher, again because only set up a resistance 2 in L ED series unit 10, compare with prior art, resistance still less, thereby the power of consumption is also littleer, L ED lamp area whole light efficiency is higher.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It is pointed out that, for the person skilled in the art, without departing from the inventive concept, several variants and modifications are possible, which all fall within the scope of protection of the invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
