Description

The LED bulb of a kind of permeability type heat abstractor of LED bulb and the heat radiation of a kind of permeability type

Technical field

The present invention relates to the LED lighting field, the LED bulb of particularly a kind of permeability type heat abstractor of LED bulb and the heat radiation of a kind of permeability type.

Background technology

The LED lamp is popular in recent years a kind of novel illumination light fixture, lamp tube type is wherein arranged, and bulb-type is also arranged, its bulb-type be called the LED bulb.Its LED light emitting source is generally straight-down negative, the LED illuminator go out light center towards exiting surface owing to receive the restriction of LED illuminator self lighting angle, often cause around the LED illuminator very brightly, radiating effect is not good, easily light decay.

The LED bulb of prior art in order to let heat scatter fast, can paste circuit board usually heat radiation supporting body dispel the heat (heat abstractor) is being installed; Its supporting body generally adopts metal material, and so, not only the weight of LED lamp obviously increases; And the structure of LED lamp becomes complicated; Manufacture craft is loaded down with trivial details, and material cost increases, and causes product cost higher.

Therefore, how to solve the heat dissipation problem of LED bulb, should good heat dissipation effect, problem simple in structure again, be one of direction of LED bulb development.

Summary of the invention

The present invention is intended to overcome the above-mentioned deficiency of prior art, and a kind of LED bulb of permeability type heat radiation is provided.Its good heat dissipation effect, radiator structure is simple, and luminous even, light efficiency is high.

For this reason, the technical scheme that addresses the above problem of the present invention is:

The LED bulb of a kind of permeability type heat radiation of the present invention; The permeability type heat abstractor that comprises a kind of LED bulb; Also comprise lampshade, circuit board, light emitting diode and supply unit; Supply unit is installed in Lamp cup, and circuit board and light emitting diode are installed in and lean on top in the Lamp cup, and circuit board is electrically connected with supply unit; Lampshade is equipped with the upper end of ventilative ring.

Technical scheme to the LED bulb of above-mentioned a kind of permeability type heat radiation is further set forth:

The radiator of metal material perhaps, is set in Lamp cup.

Make the screw thread that spins with the input power supply on the lamp holder.

The beneficial effect of the LED bulb of the permeability type heat abstractor of a kind of LED bulb of the present invention and the heat radiation of a kind of permeability type is: one of which; To change into the air ventilation heat radiation with the sheet metal heat radiation; Heat in the bulb is dispersed into rapidly in the outer air of lamp through air is mobile; Radiating effect is fine, especially under the situation of little wattage, and the radiator that fully can the alternative metals sheet be combined into.Its process is; The outer cold air of lamp A air-vent from the lamp holder flows in the Lamp cup; Absorb and take away the heat that supply unit, circuit board and light emitting diode produce and become hot-air, this hot-air flows out through the tooth of the said shoulder of ventilative ring and the said ventilative gap between the tooth lamp outside realizing from the B air-vent and dispels the heat.Its two, radiator structure becomes simply, reduces the consumption of metal material, simplifications that also become of the manufacture craft of whole bulb, the manufacturing cost decline of bulb, thus can improve the competitiveness of product in market.Its three, supporter and ventilative ring design novel ingeniously, ventilative ring is designed to gear-like, utilizes the gap of tooth and between cog to ventilate, the while ventilative ring of gear-like is unique in appearance attractive in appearance, more can attract the consumer.
