Therefore, how making full use of the structure space of conventional bulb, make the LED bulb can satisfy the standard-required of illumination, again enough heat-dissipating spaces can be provided, is problem of needing solution badly of present LED bulb structure design.
Summary of the invention
The purpose of the utility model provides a kind of environmental protection, health, energy-conservation, makes the LED bulb can satisfy the standard-required of illumination, again enough heat-dissipating spaces can be provided, the LED bulb of high efficiency and heat radiation.
The technical scheme of the utility model is: a kind of LED bulb of high efficiency and heat radiation; Comprise lamp holder, said lamp holder is connected with commutator housing, and the commutator housing port is fixed with connector; Said connector is provided with several radiators that connects together; And form the heat dissipation channel that connects between each radiator, be fixed with the aluminium base that has some lamp pearls on each radiator, the outside of radiator is fixed with reflector and passes through part.Like this; Connector is provided with several radiators that connects together, and forms the heat dissipation channel that connects between each radiator, and the heat that led light source produces carries out the cross-ventilation heat radiation through the passage between the radiator; Several radiators link together simultaneously; Heat between each radiator transmits, and makes heat radiation evenly, fast, thus the long-life of having guaranteed the LED bulb.
Preferably, said commutator housing is provided with several louvres.Like this, heat can shed from louvre, guarantees the heat circulation.
Preferably, said radiator is parabola shaped, and the said aluminium base that has several lamp pearls is fixed on the interior trough floor of parabola shaped radiator through screw.
Preferably, said reflector is connected with radiator, connector through buckle or slot.
Preferably, said radiator inside is provided with a plurality of louvres that the louvre that runs through its central axis and sidepiece are provided with its sidepiece of break-through, and the cylindrical button bit of the convexity on the said part passes connector and commutator housing is fixed on the lamp holder.
Preferably, the madial wall of said part be provided with in perpendicular line, band, the grid line a kind of, two kinds or multiple.
Preferably, inside edge, said part bottom is provided with the cylindrical button bit of 8 convexities, on connector, is provided with the button hole corresponding with button bit, and said part and connector snap together.
Preferably, the said reflector correspondence position that has the aluminium base of some lamp pearls is provided with a trapezoidal folding section portion that concaves.Like this, fluorescent tube can a plurality of directions shine, and can realize that equally full angle is luminous, makes lighting effects better.
The beneficial effect of the utility model is:
The radiator of the utility model is built-in, on the basis that does not increase LED bulb volume, enough heat-dissipating spaces is provided for the LED lamp.
The connector of the utility model is provided with several radiators that connects together; And form the heat dissipation channel that connects between each radiator; The heat that led light source produces carries out the cross-ventilation heat radiation through the passage between the radiator; Several radiators link together simultaneously, and the heat between each radiator transmits, and make heat radiation evenly, fast.
The utility model is rational in infrastructure simple, manufactures easily, and good heat dissipation effect has improved the light efficiency of LED bulb, prolongs the service life of LED bulb.
