Background technology
The application of LED on bulb lamp is very extensive, but how to use minimum cost, is designed to the bulb lamp product of superior performance, good reliability, is the challenge that each LED enterprise faces.
Generally, bulb lamp on the market has two kinds: colour rendering index 70, and its light efficiency can reach 90lm/W; Colour rendering index 80, its light efficiency reaches 60-70lm/W.These two kinds of bulb lamps are all to utilize to regulate colour rendering index to improve light efficiency.This is that technology is done to obtain good product, and other light efficiencies are lower than 60lm/W, substantially assemble, and what sell is outward appearance.In addition, the light decay of bulb lamp is all very serious on the market, is unable to undergo energy-conservation authentication.As the bulb lamp of commercialization illumination and home lighting, its colour rendering index requires to reach more than 80, could really pick out color; For the high environment of distinguishing look of the needs such as Jin Dian, tea shop, its colour rendering index requires up to more than 90.Therefore, the LED bulb lamp of incandescent lamp as an alternative, its colour rendering index should be more than 80, and so alternative ability is meaningful.
Utility model content
For the problems referred to above, the utility model provides the LED bulb lamp with ceramic heat sink of a kind of low cost of manufacture, perfect heat-dissipating, long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of LED bulb lamp with ceramic heat sink, by lamp holder, insulating base, power module, ceramic heat sink, ceramic substrate, illuminator and lampshade form, described ceramic heat sink one end is through insulating base and lamp holder socket, power module is located in lamp holder and insulating base, the described ceramic heat sink other end is connected with lampshade, described ceramic heat sink and ceramic substrate fixed bonding, illuminator is located on ceramic substrate, described ceramic heat sink is uniformly distributed a plurality of radiating fins, described ceramic substrate annular edge is along being provided with a plurality of through holes, described through hole is corresponding with the gap that radiating fin forms respectively.
Further, described lampshade is installed on described ceramic heat sink with screw thread or bonding mode.
Further, the top sides of described ceramic heat sink radiating fin is along being provided with limited ring groove.
Further, on described ceramic substrate, have the through wires hole of at least two perforations.
Further, described ceramic substrate has four through wires holes, and four through wires holes are arranged with ceramic substrate center equal angles.
From the above-mentioned description to the utility model structure, compared to the prior art, the utlity model has following advantage:
1. the utility model radiator adopts ceramic material, can meet radiating effect, and its manufacturing cost is lower again, and the manufacture craft of pottery is simple simultaneously, makes the overall cost of radiator, has met the demand in market.
