(2) the present invention has adopted fire retardation PC draw-in groove as structure carrier, be equipped with fire retardation PC plug, PC lampshade forms compact long strip shape lamp box structure, not only durable in use, readily removablely easily change, easy for installation, and the water inlet that can avoid internal component to be exposed to bringing under outdoor, the problem such as burn, the service life of guaranteeing lamp bar.
(3) the present invention has also fixed lens on circuit board, and these lens both can be for having changed the light emission direction of LED lamp pearl, can reach power saving, energy-conservation effect by LED lamp pearl again.
(4) circuit that the present invention adopts is simplified reliably, and the rectifying device of take is core, and 220V alternating current direct is switched through to the direct current for 240V, supplies with the operating circuit of the some LED of series connection; Meanwhile, in LED operating circuit loop, access a current regulator diode, guarantee that LED works for a long time in constant current state, guarantees its Luminescence Uniformity.
(5) the present invention has high, the luminous feature such as evenly of energy-saving and environmental protection, brightness, can replace traditional fluorescent lamp.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is fire retardation PC plug enlarged drawing in the present invention.
Fig. 3 is circuit diagram of the present invention.
In above-mentioned accompanying drawing, the component names that Reference numeral is corresponding is as follows:
1-fire retardation PC draw-in groove, 2-fire retardation PC plug, 3-PC lampshade, 4-LED lamp pearl, 5-rectifier, 6-jam.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment
Fig. 1 is lamp bar internal structure schematic diagram, and lamp bar length is not limit, and generally has 300mm, 600mm, 900mm and tetra-kinds of specifications of 1200mm, and the quantity of LED lamp pearl 4, between 3 ~ 20, increases along with the increase of lamp bar length.
Lamp bar shell in the present embodiment comprises that fire retardation PC draw-in groove 1 and seamless welding are in the PC lampshade 3 of fire retardation PC draw-in groove 1 over top, in the lamp bar shell that fire retardation PC draw-in groove 1 and PC lampshade 3 form, is fixed with the LED lamp pearl 4 on PC draw-in groove.
As shown in Figure 1, this lamp bar is long 300mm altogether, and LED lamp pearl 4 has 5, and series connection is fixing side by side, is respectively LED1, LED2, LED3, LED4 and LED5, and the spacing of each LED lamp pearl 4 is 60mm, and fire retardation PC draw-in groove 1 width is 36mm; PC lampshade 3 is for the protection of LED lamp pearl 4, and wherein Fig. 1 front is PC lampshade, and the back side is fire retardation PC draw-in groove 1.It should be noted that; fire retardation PC draw-in groove 1 and PC lampshade 3 are existing new technology; adopt PC material to make, not only nontoxic, odorless, tasteless, meets national all standard; and there is good mechanical performance; PC plastic products, particularly electric product, have fire prevention, fire resistance; while is holding circuit plate effectively, avoids human body contact electronic devices and components that the danger of getting an electric shock occurs.
Fire retardation PC draw-in groove 1 can embed circuit board when playing part shell, " LED cushion " function in lamp bar, completes the lighting function of LED lamp pearl 4.Circuit board is embedded to fire retardation PC draw-in groove 1 and can not only guarantee the security when circuit board operating voltage reaches 240V, reduced the volume of whole lamp bar simultaneously.
As depicted in figs. 1 and 2, after circuit board is embedded to fire retardation PC draw-in groove 1, at the two ends of fire retardation PC draw-in groove 1, each fixes a fire retardation PC plug 2 that length is consistent with fire retardation PC draw-in groove 1, width is 25mm, can play fixing, moistureproof, the waterproof of circuit board and fire-proof function, wherein this PC plug is stuck in 1 effect of fire retardation PC draw-in groove by the fixing jam 6 in centre, therefore because this PC plug is that prior art seldom explains.
For further reducing the volume of whole lamp bar, make it reach effect easy for installation, the present invention is integrated in rectifier 5 on circuit board, has saved operation and the cost of mounting adapter or waterproof dc source.
Be illustrated in figure 3 the connecting circuit figure of whole circuit board and LED lamp pearl 4.
Circuit board in the present embodiment is aluminium base, and the circuit on this circuit board comprises two parts:
First, piezo-resistance VR is by electric fuse FUS access 220V electric main, this electric fuse FUS maximum operating voltage is for exchanging 250V, when overtension, automatically fuse, holding circuit prevents the destruction of high voltage to circuit elements device, and piezo-resistance can be protected instantaneous voltage sudden change because of the electric power supply system injury to circuit;
Secondly, input is connected in parallel on the rectifier 5 on pressure-sensitive circuit, by diode D1, D2, D3, D4, completes rectification function, and rectifying device 5 is common technique in prior art, therefore do not elaborate.
In the output electrochemical capacitor C of 2.2 μ F in parallel and the resistance R of 1 megaohm of rectifier 5, the 240V DC voltage of output is carried out to filtering, make electric current more stable, now the voltage at electrochemical capacitor C two ends can directly be supplied in all LED lamp pearls 4.
As shown in Figure 2, all LED lamp pearls 4 adopt series connection form, and the advantage of series connection is that LED lamp pearl 4 damages can be extinguished all LED lamp pearls 4, prevents that lamp bar luminance nonuniformity from affecting advertisement radiation response.Further, on any one node of LED lamp pearl 4 series arms, can again connect one and prevent the current regulator diode D of LED lamp pearl 4 flickers, in the present embodiment, preferably this current regulator diode D is connected on to the end of LED lamp pearl 4 series arms.The branch road that is comprised of LED lamp pearl 4 and current regulator diode D is in parallel with electrochemical capacitor can be luminous.
In addition, on fire retardation PC draw-in groove 1, be positioned at LED lamp pearl 4 above be fixed with corresponding PC lampshade, before dispatching from the factory, adjust its position and make lamp bar luminous evenly.
Above-described embodiment is only the preferred embodiments of the present invention, and not limiting the scope of the invention, adopts design principle of the present invention in every case, and carries out non-creativeness work on this basis and the variation made, within all should belonging to protection scope of the present invention.
