(2) background technology:
As shown in Figure 1, general LED crystal particle 1 is the about 0.3 cubic millimeter crystal grain of a kind of size, it has just (P) polar region 11 and negative (N) polar region 12, and on its formation P-N composition surface (negative ions faying face), four sides, just so-called luminous zone, and be provided with a connection gasket 13 at the upper surface of crystal grain 1.Therefore, reflex to same front for LED crystal particle 1 luminous light can be concentrated, must LED crystal particle 1 all around around forming a bowl-shape reflecting surface, so this bowl-shape reflecting surface is the necessary member of light emitting diode indicator.
As shown in Figure 2, it is commonly called as light emitting diode for existing visible on the market a kind of light emitting diode indicator 2.It has two disjunct metal supports 20,21, the top of its medium-height trestle 20 is provided with a bowl-shape reflecting surface 25, a LED crystal particle 22 is placed on the bottom of bowl-shape reflecting surface 25, and is connected to another support 21 via lead 23, and then coats with epoxy resin 24.Therefore, when becoming a LED display panel with this elements combination, must be plugged in singly on the large substrate, not only plug-in unit is time-consuming takes a lot of work, and light emitting diode is difficult to be fixed on same direction, causes the brightness disproportionation phenomenon of display frame easily.
As shown in Figure 3, it is existing another kind of light emitting diode indicator 3, be commonly called as the dot matrix light emitting diode indicator, it has a printed circuit board (PCB) 30 and a plastics external member 35 that is provided with a plurality of bowl-shape reflectings surface 34, this printed circuit board (PCB) 30 is provided with a plurality of LED crystal particle 32, and each is connected with circuit junction on the printed circuit board (PCB) via a lead 33, and these bowl-shape reflecting surface 34 correspondences on this plastics external member 35 be around in each LED crystal particle 32 around, and combine with printed circuit board (PCB) 30, then, add full space therebetween with solid-state epoxy resin 31.Though this kind light emitting diode indicator 3 is easy to be combined into display panel, because its bowl-shape reflecting surface is to be made by plastics (preventing and the printed circuit board (PCB) short circuit), reflecting effect is the bowl-shape reflecting surface 25 of the metal of light emitting diode 2 as described above not.
In addition, the neither function of above-described two kinds of light emitting diode indicators with lighting at two sides, therefore, if in the time of need carrying out the double-side demonstration, the existing practice is directly two light-emitting diode display panel back ofs the body to be pasted back of the body group to be located at together, yet such practice not only can't be saved the cost of circuit base material, but also will increase by one assembling formality.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of light emitting diode indicator of the tool lighting at two sides of being convenient to make.
For achieving the above object, the utility model is taked following technical measures:
