Fig. 3 is circuit diagram of the present utility model.
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 utility model is described in further detail, and embodiment of the present utility model includes 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, is fixed with the LED lamp pearl 4 on PC draw-in groove in the lamp bar shell that fire retardation PC draw-in groove 1 and PC lampshade 3 form.
As shown in Figure 1, this lamp bar long 300mm altogether, 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; effectively holding circuit plate of while, 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 play part shell, " LED cushion " function in lamp bar in, 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 in the time that 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, a fire retardation PC plug 2 that length is consistent with fire retardation PC draw-in groove 1, width is 25mm on each the fixing in the two ends of fire retardation PC draw-in groove 1, can play fixing, moistureproof, waterproof and fire-proof function to circuit board, wherein this PC plug is stuck in fire retardation PC draw-in groove 1 by the fixing jam 6 in centre and acts on, therefore because this PC plug is that prior art seldom explains.
Make it reach effect easy for installation for further reducing the volume of whole lamp bar, the utility model 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, in the time of overtension, automatically fuse, holding circuit prevents the destruction of high voltage to circuit elements device, and piezo-resistance can be protected the injury suddenling change to circuit because of the instantaneous voltage of electric power supply system;
Secondly, input is connected in parallel on the rectifier 5 on pressure-sensitive circuit, completes rectification function by diode D1, D2, D3, D4, 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 that LED lamp pearl 4 is glimmered, 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 made up 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 preferred embodiment of the present utility model; the not restriction to the utility model protection domain; in every case adopt design principle of the present utility model, and carry out non-creativeness work on this basis and the variation made, within all should belonging to protection domain of the present utility model.
