Detailed description of the invention
For the ease of understanding the utility model, below in conjunction with accompanying drawing, the utility model is further detailed.
As shown in Figure 1, a kind of segmented LED curved surface of the utility model lamp bar, comprises lamp bar group 1, and lamp article group 1 consists of electric wire connection the first lamp article section 11, second lamp article section the 12, the 3rd lamp article section 13 and the 4th lamp article section 14.First lamp article section 11, second lamp article section the 12, the 3rd lamp article section 13 and the 4th lamp article section 14 are all printed board; During connection, the first lamp bar section 11 and the second lamp bar section 12 are first connected, and same 3rd lamp article section 13 and the 4th lamp article section 14 are also by coupled in series, and two groups of lamp bar sections then after series connection are connected by mode in parallel again.Lamp bar group 1 overall structure is curved, and arc curvature equals the curvature of backboard and heat sink.Because being not be fixedly connected with between each lamp bar section, and leave certain interval, therefore the curvature of lamp bar group 1 can change as required.In the present embodiment, the curved surface whole set of television curvature that the utility model is suitable for is 4000rad, the heat sink used and backboard also adopt identical curvature 4000rad, and need when lamp bar group 1 is assembled to be connected with heat sink and backboard, therefore the curvature of lamp bar group 1 is arranged to 4000rad too.
As shown in Fig. 2 to Fig. 5, in described first lamp article section 11, second lamp article section the 12, the 3rd lamp article section 13 and the 4th lamp article section 14, all laid out in parallel has the LED lamp bead of equal number.In the utility model, the quantity of LED lamp bead is upper 36 of every section of lamp bar section, in parallel again after every 9 LED lamp pearls are connected into 4 groups.Single LED lamp pearl specification voltage and specification electric current are respectively 6.3V and 120mA.Be called passage one after first lamp bar section 11 and the series connection of the second lamp bar section 12, voltage specification and the current specification of passage one are respectively 113.4V and 480mA; Be called passage two after 3rd lamp article section 13 and the series connection of the 4th lamp article section 14, voltage specification and the current specification of passage two are respectively 113.4V and 480mA.The power supply used needs two passages, and power supply specification voltage and specification electric current are 113.4V and 480mA.
Concrete, as shown in Fig. 6 to Fig. 8, the both sides up and down of LED lamp bead are parallel is provided with graduation mark.Can determine whether LED lamp bead is in place according to this graduation mark.
Concrete, as shown in Fig. 6 to Fig. 8, centre and the two ends of the first lamp article section 11, second lamp article section the 12, the 3rd lamp article section 13 and the 4th lamp article section 14 are all provided with projection 111.Although lamp bar section is Precision Machining part, curvature tolerance is very little, and during owing to producing in batches, the curvature margin of tolerance of backboard is 0-400rad, just there is certain error when such lamp bar section and heat sink assembling.Projection 111 now in the middle of lamp bar section just can be used for locating, and during enforcement, the width of middle projection 111 is set to 10mm, and the recess width of the heat sink matched is set to 10.3mm, limits the left and right activity of lamp bar section with this; And the projection 111 at lamp bar section two ends can be used for locating above-below direction.Meanwhile, except projection 111 that is middle and two ends, left and right, other sideline of lamp bar section and heat sink keep the unsettled distance of 0.8mm.By above-mentioned structure, the optical effect that lamp bar group 1 produces because of error when assembling with backboard, heat sink three effectively can be reduced.
Concrete, as shown in Figure 6, Figure 7, one end that described first lamp article section 11, second lamp article section the 12, the 3rd lamp article section 13 and the 4th lamp article section 14 interconnect is provided with stair-stepping projection near projection.This projection makes lamp bar section is used for the projection 111 of locating and non-locating part and has certain difference in height, can reduce the lamp shadow that heat sink out-of-flatness causes.
Concrete, the first lamp article section 11, second lamp article section the 12, the 3rd lamp article section 13 and the 4th lamp article the section 14 upwards centre of one side and two ends are provided with jacking block 112, and the size of centre position jacking block is greater than the jacking block at two ends.Jacking block 112 is used for locating and supporting light guide plate.Light guide plate pushes down the jacking block at lamp bar section two ends, can prevent lamp bar section edge warping.The jacking block in centre position also needs for supporting reflex paper, and the jacking block at the ratio two ends of therefore size setting is slightly large.
Concrete, as shown in Figure 8, the place of interconnecting of the first lamp article section 11, second lamp article section the 12, the 3rd lamp article section 13 and the 4th lamp article section 14 all leaves space.Because during batch production, backboard has the curvature tolerance of 0-400rad, when lamp bar group 1 is assembled with heat sink and backboard, certain interference may be produced, therefore reserve certain space in the junction of each lamp bar section, can prevent lamp bar section edge from mutually interfering.
Concrete, as shown in Figure 8, the edges at two ends place of the first lamp article section 11, second lamp article section the 12, the 3rd lamp article section 13 and the 4th lamp article section 14 is all provided with chamfering 113.The collision brought when arranging this chamfering in order to reduce assembling, in order to avoid damage lamp bar section.
