Detailed description of the invention
Referring to figs. 1 through Fig. 4, this utility model embodiment is described further.
As shown in Figure 1, a kind of anti-aging light bar, including flexible circuit board 1, the LED lamp bead 2 that is welded in described flexible circuit board 1, the layer of silica gel 3 of encapsulation LED lamp bead 2, described layer of silica gel 3 is rectangle, the both sides of described layer of silica gel 3 are provided with air-vent 4, and described air-vent 4 communicates with lamp bead, a diameter of 0-2mm of described air-vent 4.LED lamp bead 2 has certain power consumption, therefore after energising, LED lamp bead 2 in flexible circuit board 1 can have certain temperature, it is thus desirable to distribute, if layer of silica gel 3 is sealed in LED lamp bead 2, the heat conduction that will make LED lamp bead 2 is slower, therefore the accumulation of heat can be produced, by air-vent 4, effectively heat can be swapped by cold airflow in air, thus reach the effect of cooling.The end of flexible circuit board 1 is provided with three rectangles and adds semicircular pad 5, this pad 5 is for connection to DC source, in fig. 2, DC+ is direct power supply, access in the present embodiment is 3 line DC sources, thus realize 3 lamp bars 7 and be operated simultaneously so that LED lamp bead 2 can be lighted simultaneously.
The both sides of layer of silica gel 3 arrange air-vent 4, so that the heat of LED lamp bead 2 can be with Quick diffusing, and a diameter of 0-2mm due to air-vent 4, such that it is able to avoid the entrance of water droplet, if and light bar heating in the case of, although air-vent 4 does not enters water droplet, water droplet can stay air-vent 4 exit, in the case of light bar is generated heat, water droplet directly absorbs heat and evaporates, such that it is able to take away some heats of light bar, such that it is able to accelerate cooling rate, such that it is able to improve overall service life, reduce the scrappage of light bar.
As shown in Figure 1, 2, the pad 5 being provided with ellipse of flexible circuit board 1.By above-mentioned setting, oval pad 5 makes in process of manufacture, LED lamp bead 2 can be with rapid welding on pad 5, owing to LED lamp bead 2 needs dripping solder stick on pad 5 in welding process, owing to being oval, therefore solder stick is melted in the shape on pad 5 and can form the salient point of ellipse, owing to it has horizontal tension force, so can fix with rapid shaping LED lamp bead 2 is placed on pad 5 when, improve working (machining) efficiency, accelerate to produce.Described LED lamp bead 2 equidistantly arranges in " one " font.LED lamp bead 2 can comprehensive be arranged, but horizontal and vertical " one " font arranges more preferred, and by above-mentioned setting, structure is compacter, welds convenient, simple structure.Described current-limiting resistance 8 oblique arrangement so that the position of current-limiting resistance 8 is compacter, saves spatial arrangement.
As in figure 2 it is shown, this kind of light bar every meter has 264 lamp bead, its flash effect is the form of entire row bounce flash, after using different colours lamp bead, effect is the most gorgeous attractive in appearance, has preferable decorative effect, and lamp bead uses paster encapsulation model, volume is little, low cost, is more favorable for manufacturing.
As it is shown on figure 3, described LED lamp bead 2 is welded with pad 5, forming lamp group 6 after the parallel connection of two LED lamp bead 2, form lamp bar 7 by current-limiting resistance 8 series connection between described some lamp groups 6, described lamp bar 7 has been arranged side by side 3 rows.The color combination of 3 bank light pearls can be: white-blue-warm white；Red-green-blue；An independent warm white；An independent white；An independent blueness；An independent redness；An independent green；An independent pink colour, other colors such as independent yellow, each color can be with independent assortment.
In every rice lamp band, the number scope of lamp bead can be 72-360, and light bar 0-100m can be used, and the width range of flexible circuit board 1 is 5-18mm, and preferable width is 15mm.3 rows can be formed and arrange jumping, excellent decoration effect.
In the drawings current-limiting resistance 8 be numbered R1, R2, R3 etc.; setting by current-limiting resistance 8; can the effective LED lamp bead 2 in protection circuit; LED lamp bead 2 has the power of self; need to carry out limiting electric current by current-limiting resistance 8; such that it is able to avoid electric current excessive, and LED lamp bead 2 is operated under over-current state, reduces service life.By above-mentioned setting, simplifying circuit layout structure, and make the power consumption of each LED lamp bead 2 more uniformly, caloric value is the most uniform, simultaneously so that it is more convenient to produce, and welds convenient.
So that the Integral decoration of light bar is more attractive in appearance, light has multiple color, and described LED lamp bead 2 is one or more in R lamp bead, G lamp bead, B lamp bead, colourless lamp bead, white paster lamp bead, warm white paster lamp bead, pink colour paster lamp bead.Can be with independent assortment by above color, by above-mentioned setting so that light there is the combination of different color, excellent decoration effect.This money light bar preferred version is for using white, warm white, blue paster lamp bead.
As shown in Figure 4, flexible circuit board 1 scribbles TPV layer 9.By above-mentioned setting, due to TPV this under the conditions of water smoke, ozone, outside atmosphere are aging etc., chemical stability is excellent, therefore can effectively prevent flexible circuit board 1 aging.
In sum, this programme effectively reduces LED lamp bead 2 and is energized in flexible circuit board 1 temperature during using, thus provides overall service life, prevent aging, and adjust the LED lamp bead 2 on the circuit of entirety and the arrangement of current-limiting resistance 8, it is simple to produce, accelerate production efficiency.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
