Embodiment
Below in conjunction with accompanying drawing, introduce in detail the utility model light-emitting diode assembly structure.
As depicted in figs. 1 and 2, the utility model light-emitting diode assembly comprises substrate 1, and substrate 1 includes insulating barrier and is arranged on conductive electrode on the insulating barrier; Support 2, support 2 forms the indent opening, and forms the bowl cup structure with substrate 1, and support 2 forms first bowl of cup 41 and second bowl of cup 42 with substrate 1, and substrate 1 corresponding first bowl of cup 41 and second bowl of cup 42 are provided with the first conductive electrode 11 and the second conductive electrode 12; Light-emitting diode chip for backlight unit, the first light-emitting diode chip for backlight unit 31 is arranged in first bowl of cup 41, the second light-emitting diode chip for backlight unit 32 is arranged in second bowl of cup 42, the first light-emitting diode chip for backlight unit 31 is electrically connected with the first conductive electrode 11, and the second light-emitting diode chip for backlight unit 32 is electrically connected with the second conductive electrode 12; Fluorescent glue is filled with in first bowl of cup 41 in 51, the second bowls of cups of the first fluorescent glue and is filled with the second fluorescent glue 52.The present embodiment only is used for explanation the utility model structure, in actual applications, can be provided with a plurality of bowls of cup structures as required, does not affect the utility model enforcement and application.
The first light-emitting diode chip for backlight unit 31 and the second light-emitting diode chip for backlight unit 32 can be the different capacity chip.The cost of two lower powered light-emitting diode chip for backlight unit is lower than a high-power light-emitting diode chip for backlight unit cost, and therefore, the utility model light-emitting diode assembly can effectively reduce production costs in the situation of the Integral luminous power that guarantees the light-emitting diode device.The luminous flux that luminous flux when the first light-emitting diode chip for backlight unit 31 and 32 work of the second light-emitting diode chip for backlight unit also sends greater than a high power LED chip, therefore, the utility model light-emitting diode assembly has advantages of that luminous flux is large.
As depicted in figs. 1 and 2, first bowl of cup 41 is less than second bowl of cup 42, simultaneously, the first light-emitting diode chip for backlight unit 31 is arranged at first bowl of cup 41 and second bowl of cup, 42 relative middle positions with the second light-emitting diode chip for backlight unit 32 correspondences, with luminously not stopping and absorption between mutually of guaranteeing chip in the bowl cup, thereby improve luminous flux output.
The first conductive electrode 11 and the second conductive electrode 12 are electrically connected with external circuit respectively, thereby make the first light-emitting diode chip for backlight unit 31 and the second light-emitting diode chip for backlight unit 32 can be as required, adopt the modes such as parallel connection, series connection, independent control to be electrically connected, thereby make the first light-emitting diode chip for backlight unit 31 and the second light-emitting diode chip for backlight unit 32 as required, luminous or simultaneously luminous separately, the utility model light-emitting diode assembly is used flexibly, can satisfy different light demands.
The first fluorescent glue 51 and the second fluorescent glue 52 are filled in first bowl of cup 41 and second bowl of cup 42 interior resolution, in order to satisfy different luminous requirements, the first fluorescent glue 51 can be different fluorescent glues with the second fluorescent glue 52, thereby the light that first bowl of cup 41 sent is photochromic different from the light that second bowl of cup 42 sends, and further increases the application of the utility model light-emitting diode assembly and uses flexibility ratio.
This light-emitting diode assembly, owing to having adopted two bowls of cup structures, the heat radiation of two bowls of cups, the equal independent design of circuit can be avoided the stack of heat, are conducive to prolong the useful life of product.Simultaneously when light-emitting diode chip for backlight unit goes wrong (short interruption etc.) in the bowl cup, light-emitting diode chip for backlight unit still can work in another bowl cup, can guarantee that whole module or light fixture still can normally use needn't maintain and replace, is conducive to guarantee the reliability and stability of product.
Be the utility model case study on implementation only below, be not limited to the utility model, as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection range of putting down in writing in claims.
