Abstract
The utility model relates to a high-power LED plane light source, which includes a plurality of LEDs arranged in rows and a printed circuit board, wherein the LEDs are fixed on the printed circuit board; the LEDs in each row comprises first LEDs and second LEDs which are arranged at intervals, the first LEDs and the second LEDs which are arranged in the same row are connected in series respectively, and first LEDs connected in series and the second LEDs connected in series are connected in parallel. The high-power LED plane light source has better optical uniformity, and can effectively prevent the dark field phenomenon.
Description
Technical field:
The utility model relates to the LED field, relates in particular to a kind of structure of high-power LED plane light source.
Background technology:
The application technology of LED has spread all over the world, all trades and professions are all being used the LED technology, little screen to the mobile phone consumer electronics arrives automobile tail light greatly, and big lighting apparatus, low side ordinary individual's lighting apparatus arranged, high-end have a LED LCD TV, widelyd popularize in market at present, and the advantage of LED is very obvious, its advantage also is that everyone knows about it, yet itself also has inevitable inferior position and shortcoming.High-power LED plane light source comprises LED and printed circuit board in the prior art, and LED is fixed on the printed circuit board.Wherein several LED that become row to be provided with are connected into one group, and are close to, if wherein any one has been gone bad, then whole group LED can knock out, and so corresponding source region has tangible deepening, influences the normal use of planar light source.Especially work as planar light source and be applied in medical aspect, its brightness requirement is very high, be to be combined by a large amount of high-power LED plane light sources, yet the structure of this high-power LED plane light source causes tangible details in a play not acted out on stage, but told through dialogues phenomenon and non-uniform light problem easily.
The utility model content:
The purpose of this utility model is to provide a kind of high-power LED plane light source, thereby better solves the optical uniformity and the details in a play not acted out on stage, but told through dialogues problem of high-power LED plane light source.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of high-power LED plane light source, comprise and be some LED and the printed circuit board that number row is provided with, described LED is fixed on the printed circuit board, it is characterized in that: every row LED comprises a LED and the 2nd LED that is provided with at interval, wherein a LED and the 2nd LED with row is cascaded separately, and a LED who is cascaded is in parallel with the 2nd LED that is cascaded.
The beneficial effects of the utility model are: a described LED is one group of series connection, can see from connected mode, if one of them LED breaks down, this group series LED also can go out entirely so, but the 2nd LED with delegation just in time is adjacent and cross arrangement, can give optical compensation, can not have influence on whole effect thereby product can continue to use.Even all LED all break down, planar light source the 2nd LED so as a whole can recompense, and is equivalent to the LED arranging density and diminishes, brightness can decrease naturally, but brightness uniformity is still good, can not cause certain significantly details in a play not acted out on stage, but told through dialogues of zone, so product can continue to use.
Description of drawings
Fig. 1 is the structural representation that meets high-power LED plane light source of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Please refer to Fig. 1, high-power LED plane light source 1 comprises some LED10 of being number row and being provided with, 20 and printed circuit board 30, and described some LED10,20 are fixed on the printed circuit board 30.Describedly be some LED10 that number row is provided with, each row of 20 is connected in parallel.Wherein every row LED comprises a LED10 and the 2nd LED20 that is provided with at interval, and wherein a LED10 and the 2nd LED20 with row is cascaded separately, and a LED10 who is cascaded is in parallel with the 2nd LED20 that is cascaded.
A described LED10 is one group of series connection, can see from connected mode, if one of them LED10 breaks down, a LED10 of this group series connection also can go out entirely so, but the 2nd LED10 with delegation just in time is adjacent and cross arrangement, can give optical compensation, can not have influence on whole effect thereby product can continue to use.Even all LED10 all break down, planar light source the 2nd LED20 so as a whole can recompense, and is equivalent to the LED arranging density and diminishes, brightness can decrease naturally, but brightness uniformity is still good, can not cause certain significantly details in a play not acted out on stage, but told through dialogues of zone, so product can continue to use.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not once be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (2)
