Description
Technical field
The utility model relates to the LED lighting field, further, relates to a kind of indoor LED lighting bulb that is applied to.
Background technology
LED is energy-conservation, efficient with it, and the advantage of environmental protection progressively substitutes the traditional lighting light source.But because the led light source volume is little, the brightness height, the heat of its generation is more concentrated, therefore uses the lighting of LED as light source, effectively solves its heat dissipation problem and just becomes particularly important.
Present common LED lighting, the overwhelming majority is provided with huge and heavy heat abstractor by the heat conduction heat to be distributed.This structure and heat dissipating method are nowhere near to high-power LED light source, therefore, occur that led light source is easy to be burnt out and the normal use that influences whole light fixture.
The utility model content
The utility model provides a kind of LED lighting bulb of indoor application for solving the problems of the technologies described above, and not only its structure is light and handy, and good looking appearance is suitable for room lighting, and can effectively improve radiating efficiency, prolongs the life-span of LED, guarantees the normal use of LED illuminating lamp.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of indoor LED lighting bulb, comprise led light source and install led light source wiring board, the printing opacity face shield that is located at the led light source outside and the lamp holder that is electrically connected, it is characterized in that: described wiring board is bonded on the heat abstractor, described heat abstractor is made into integration by the radiator of hollow and the chimney-like hollow cylinder that is positioned on radiator one end face, along described radiator a plurality of radiating fins are set at interval circumferentially, the compartment of described radiator, chimney-like cylinder and radiating fin forms a plurality of direct and cross-ventilated heat dissipation channels.
Further, described LED lighting bulb also comprises the housing of a built-in power supply, and this shell nozzle one end is provided with a dismountable cover plate and is connected with radiator, and the other end is connected with lamp holder.
Further, between described radiating fin, be provided with radiator and described cover plate, the reference column of housing mechanical connection and the through hole that power supply road positive and negative lead wires passes.
Further, described wiring board is a ring-type, and its center is passed the chimney-like cylinder and is bonded on the radiator end face by heat conductive silica gel.
Further, the inwall of described chimney-like cylinder is provided with fin.
Further, after described printing opacity face shield cover is buckled in described led light source, its lower limb and described radiator closely fasten and sealing, and its top edge leaves an opening that cooperates with described chimney-like cylinder outer wall, and described chimney-like cylinder mouth is exposed to OFP by described opening.
The beneficial effect that the utility model brings:
The wiring board that is welded with led light source is bonded on the radiator end face by the coating heat conductive silica gel, heat is transmitted on the heat abstractor, what the compartment of radiator, chimney-like cylinder and the radiating fin that is communicated with by hollow formed again a plurality ofly directly dispels the heat with cross-ventilated passage, improve radiating efficiency greatly, thereby made the purpose that is issued to effective solution heat dissipation problem in the situation that does not need to increase heat sink material and increase light fixture weight.
