Description
Technical field
The utility model relates to a kind of indoor illumination light fitting, the special efficient LED Grille lamp that relates to a kind of semiconductor light-emitting-diode (led light source) technology.
Background technology
In lighting technical field, contain a large amount of mercury vapours in indoor traditional fluorescent lamp, if broken mercury vapour then can evaporate in the atmosphere, existing LED fluorescent lamp does not then use mercury, and the LED product is not leaded yet, and environment is played a protective role.The LED fluorescent lamp is known as the green illumination of 21st century.The LED fluorescent lamp is installed fairly simple; Its independent power source is built-in and external two kinds, when the LED fluorescent lamp of on-chip power is installed, original fluorescent lamp is taken off change the LED fluorescent lamp; And ballast and starter removed; Let the 220V electric main directly be added to LED fluorescent lamp two ends and get final product, the external LED fluorescent lamp of power supply generally is furnished with special-purpose lamp bracket, changes original just can having used.But the life-span with respect to the lamp pearl can reach 80,000 hours and ratio, power supply internal electronic component have only 3,000 or 4,000 hours life-span, differ greatly by contrast.
The utility model content
The purpose of the utility model is to provide a kind of efficient LED Grille lamp of power supply external.
For realizing above-mentioned purpose; The technical solution of the utility model is: a kind of efficient LED Grille lamp; Comprise the grid lampshade, be fixed in the constant-current driving power supply on the grid lampshade, lampshade reflector and at least one fluorescent tube that is installed in the interior LED fluorescent lamp base of grid lampshade that the grid lampshade is interlocked; Wherein, said fluorescent tube by the heat radiation aluminium section bar, be fixed in the aluminium base of heat radiation under the aluminium section bar, paster LED light source and the PC bar cover of being located under the aluminium base constitutes.
Said constant-current driving power supply connects the constant current control module by the input of line voltage, connects fluorescent tube by the output of constant current control module again.
Said constant current control module adopts BP2808 constant current control chip.
With fixedly plug screw locking, its two ends are with plastic cement plug jam-pack between said shaped material of radiator and the PC bar cover.
Said paster LED light source is divided into the arrangement of many group lamp strings by duplicate rows or single file and is welded in the aluminium base bottom.
Said aluminium base coated with thermally conductive silicone grease is adhered to heat radiation aluminium section bar below.
Through adopting above-mentioned technical scheme; The beneficial effect of the utility model is: thus the LED Grille lamp of the utility model is realized the constant of led light source average current through source drive and constant current compensation technique are arranged, and effectively reduces power consumption, improve constant current accuracy, improves power-efficient; The power supply of external makes maintenance and keeps in repair convenient; A power supply can be with many fluorescent tubes, makes the energy saving more of LED lamp, longer service life.
Description of drawings
Fig. 1 is the structural representation of a kind of efficient LED Grille lamp of the utility model;
Fig. 2 is the circuit theory diagrams of constant-current driving power supply in the utility model.
(identify among the figure: 1, grid lampshade, 2, constant-current driving power supply, 3, fluorescent tube, 31, shaped material of radiator, 32, aluminium base, 33, the paster LED light source, 34, PC bar cover, 35, fixing plug screw, 36, the plastic cement plug, 5, reflector)
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1; A kind of efficient LED Grille lamp of the utility model is welded in aluminium base 32 bottoms with paster LED light source 33 by three groups of lamp strings arrangements that triplex row is divided into every group of 18 lamp pearls, and aluminium base 32 coated with thermally conductive silicone grease are adhered to heat radiation aluminium section bar 31 belows; Use fixedly plug screw 35 lockings between said shaped material of radiator 31 and the PC bar cover 34; Its two ends form fluorescent tube 3 with plastic cement plug 36 jam-packs again, and constant-current driving power supply 2 is fixed on the grid lampshade 1, the output of constant-current driving power supply 2 is connected in cable (notes both positive and negative polarity during wiring) on each LED fluorescent lamp base 10 again; Fasten upper lamp shade reflector 5 again; Three fluorescent tubes 3 that will form at last, according to anodal and anodal, the mode of negative pole and negative pole; Be fixedly installed in respectively on the LED fluorescent lamp base 10 in the grid lampshade 1, finally form the efficient LED Grille lamp.
As shown in Figure 2; Constant-current driving power supply 2 is imported by the AC220V electric main in the utility model; Behind the filter filtering through constant-current driving power supply 2 inside; After the rectifier bridge rectification, give BP2808 constant current control chip IC1 circuit supply behind the constant current compensation voltage stabilizing, BP2808 constant current control chip IC1 internal logic carries out constant current control in the monocycle after; Its positive electricity level and negative electricity level are to three fluorescent tube U1, U2, U3 constant current power supply; The positive pole of BP2808 constant current control chip IC1 connects the positive pole of three fluorescent tube U1, U2, U 3, and its negative pole connects the negative pole of three fluorescent tube U1, U2, U3, thereby realizes that one group of driving power drives three fluorescent tube U1, U2, the luminous work of U3.
