The case thereof is adopted as a lighting source for a semiconductor, and fully plays the performance advantages of LED when entering the market of general lighting, thereby greatly improving the luminous efficiency.

A kind of power type light-emitting diode

Technical field

The utility model relates to a kind of power type light-emitting diode.

Background technology

The advantage of LED is widely known by the people, has brought into play huge advantages such as energy-conservation, long-lived, that response speed is fast in applications such as view, indication, demonstration, backlight, special lightings.In the one-hundred-year history of lighting technology development, the development of LED is decades only, but are applied as the master with low power LED in the past always.We can see that LED is easy in the dynamic control of brightness and color, overall dimension is little, do not contain infrared ray and ultraviolet ray in long-life, light beam, very strong characteristics such as light emission direction are the advantages that LED marches the general lighting field on a large scale.Want to give full play to the performance advantage of LED, enter general lighting market, must develop power type light-emitting diode, improve luminous efficiency.

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.

Small rack can be the prismatic ring stand of metal material, promptly can be and the last prism cross section opposite position of shell and the prismatic ring stand of size, also can be slightly different, be rhombus ring stand cylindrical, square or more than the Mitsubishi.

Light-emitting diode chip for backlight unit is luminous to be that full angle is luminous, the design that is coated in the outer glue-line of chip and support can determine its whole luminous angle, the utility model by the multicore sheet position grouping and be coated in chip and glue that support is outer is selected for use is transparent and has the light refraction effect that making the whole lighting angle of this novel power type light-emitting diode is 360 °.

Described shell and small rack material surface are coated with silver, nickel or other metal levels that plays reflection ray, prevents the support oxidation.

The last prismatic ring body of described shell is more than the triangular, is generally the 3-10 rib, preferably 8 prisms.

Described small rack is preferable with the corresponding prismatic ring stand of last prism cross section of shell, but also different shape.

Described one group of diode chip for backlight unit can be single, can also be a plurality of, is distributed on the shell.When being a plurality of, if the quantity of one group of diode chip for backlight unit is consistent with the rib number of the last prismatic ring body of shell, then each diode chip for backlight unit places on the face of shell.
