And power-type LED in the market mainly is based on Surface Mount type structure, and there is angle limits in this structure, be used for general lighting, must carry out many to it and could use after being assembled into module.
Summary of the invention
The purpose of this utility model provides a kind of power type light-emitting diode that can directly be used as illumination, utilizes its shell as semiconductor illuminating light source.
For achieving the above object, the utility model is taked following design:
A kind of power type light-emitting diode, by support and placed on it by glue apply LED chip close and constitute, described support comprises shell and small rack, both are metal material and make, shell is made of last prismatic ring body and following circular platform type reflector two parts zoarium, is formed centrally cavity during shell is interior; Small rack is the prismatic ring stand, stands on the shell; Small rack is put at interval mutually with the shell of support, reaches therebetween and fills megohmite insulant in the shell cavity; The insulant that the utmost point of being drawn by small rack was worn rack bore prolongs to the bottom; The bottom of circular platform type reflector is connected to the screw thread cylinder that plays location, thermolysis; Described one group of diode chip for backlight unit cloth is on shell, and a utmost point of each diode chip for backlight unit is electrically connected with small rack, and another reversed pole forms with shell and is electrically connected.
The last prismatic ring body of described shell is more than the triangular.Described small rack is the corresponding prismatic ring stand of last prism cross section with shell.
Described one group of diode chip for backlight unit is distributed on the shell.
Described shell and small rack surface are coated with the metal level that plays reflection ray, prevents the support oxidation.
The utility model has the advantages that:
1, the metallic support thermal resistance is little, and both conducting was electrical, can serve as heat sinkly again, improves heat dispersion, and the heat energy that produces during light-emitting diode is used distributes, and improves its useful life,
2, inherent luminescence diode chip for backlight unit on each face of support shell, the encapsulation back forms multicore sheet integrated light-emitting diode, and its operating current uses different light-emitting diode chip for backlight unit more than 320mA, and power can reach 1W, 3W or higher.
3, lighting angle is 360 ° of full-shapes, both can many assembling use, also can single directly apply to illuminating product.
Description of drawings
Fig. 1 is that the utility model one example structure schematic diagram (is not with the glue seal; Half section).
Fig. 2 is another example structure schematic diagram of the utility model (band glue seal, main looking).
Embodiment
Consult Fig. 1, shown in Figure 2, the utility model power type light-emitting diode comprises support and light-emitting diode chip for backlight unit.
