Abstract
The utility model discloses a bulb radiating outer shell which comprises a shell body and a base. The shell body and the base are fixedly arranged. The shell body comprises an outer layer shell body and an inner layer shell body, the outer layer shell body and the inner layer shell body are fixedly arranged, at least one circle of annular hollow part is arranged on the waist portion of the shell body, cooling fins are arranged on the outer layer shell body, the number of the cooling fins is at least two, and the cooling fins are vertically and evenly arranged on the outer surface of the outer layer shell body. The shell body is of a double-layer design, the inner layer shell body isolates the metal outer layer shell body by thermal conductive plastics, namely the effects of thermal conduction and insulation are achieved, and safety and reliability are achieved. The design of the cooling fins and the hollow part enhances the cooling function of the shell body, the inside temperature is made to be lowered quickly, and the service life of a bulb is prolonged.
Description
Technical field
The utility model relates to a kind of bulb shell, relates in particular to a kind of bulb shell that dispels the heat.
Background technology
A lot of LED electronic bulbs is arranged in the market, owing to being electronic product, so the electronic unit of LED bulb is subjected to the impact of temperature very much, work for a long time, temperature in bulb can reach very high, and as cooling not in time, can greatly reduce the service life of LED bulb, even there is now the metal shell of part to increase its heat dispersion, the charged safety problem that also can increase bulb in this of metal shell on market.
The utility model content
The utility model, for the deficiencies in the prior art, provides a kind of excellent in heat dissipation effect, the bulb heat radiation shell of good insulation preformance.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of bulb heat radiation shell, comprise housing and base, described housing and base are fixedly installed, described housing comprises outer casing and internal layer shell, outer casing and internal layer shell are fixedly installed, and described housing waist arranges at least one ring shape hollow out, is provided with fin on described outer casing, at least two of fin, the fin Vertical Uniform is arranged at the outer casing outer surface.
Described fin arranges with annular hollow out is vertical.
Described internal layer shell is heat-conducting plastic, and outer casing is metal shell.
Described fin is metal fin.
Compared with prior art, the beneficial effect that has is: the double layer design of housing, internal layer shell use heat-conducting plastic that the outer casing of metal is separated, and namely are implemented to heat conduction and also reach the effect of insulation, and be safe and reliable; The design of fin and hollow out has increased the heat sinking function of housing, and inner temperature is reduced fast, extends the service life of bulb.
