Description

Integral LED bulb

Technical field

The present invention relates to a kind of integral LED bulb.

Background technology

In recent years, along with the develop rapidly of lighting engineering industry, light emitting diode (LED) has the plurality of advantages such as high brightness, low energy consumption, long service life, environmental protection with it, is widely used in all a plurality of fields of illuminating industry.

Along with the development of application demand, high-power lamp bulb need to get more and more.But as a feature of solid light source itself, the heat that more high-power LED sends when work is higher.Can these heats that send derive in time or distribute, and becomes the key factor that affects LED bulb luminescent quality and life-span.

Existing LED bulb is mainly comprised of lamp holder, lamp socket, driver, radiator, LED light source assembly, diffuser etc.:

LED bulb is to adopt reflective device to carry out a luminous intensity distribution, and LED light source assembly is arranged on a side of substrate, and the opposite side of substrate arranges fin; All heats can only dispel the heat by the fin of substrate opposite side is set, and its shortcoming is that area of dissipation is little, and power cannot be done greatly; Total output light flux of LED bulb is low, and reflecting and light distributing light loss is large, and overall system efficiency is low.

Separately having a kind of LED bulb is that LED light source is integrated on a stem stem, is placed in the cell-shell of sealing; All heats can only partly dispel the heat by the stem stem outside the cell-shell of sealing, and its shortcoming is that radiating efficiency is extremely low, and LED bulb power cannot be done greatly, and the whole light output of LED bulb is low, is difficult to meet customer requirement.

The heat dispersion of the LED bulb of prior art is not good enough, is difficult to guarantee high-power LED bulb luminescent quality and life-span.

Summary of the invention

The object of this invention is to provide the very large radiator of needs existing in a kind of integral LED bulb solution prior art and meet whole lamp heat radiation requirement and baroque problem.

Technical solution of the present invention is:

An integral LED bulb, comprises radiator and the light-source chamber, the actuator chamber that set gradually, the cavity of described light-source chamber for being formed by diffuser radiator, and radiator is provided with LED light source assembly, and described actuator chamber is served as reasons and is driven and lamp socket composition;

Described radiator consists of installation base plate and more than one radiator, the lower end of described radiator is vertically inserted on installation base plate, described radiator be take the central shaft of installation base plate and is uniformly distributed as axle, and between radiator, there is certain interval, form the axial outer emitting shape heat dissipation channel of described substrate center, radiator and diffuser are assembled, and the upper end of radiator is stuck in diffuser top groove, and described installation base plate rides on the bent angle of diffuser bottom.

Further, on described installation base plate, have air vent, air vent is communicated with actuator chamber and heat dissipation channel, lamp socket is provided with the transverse slat of fixed drive, driving is perpendicular to transverse slat setting, and transverse slat has air-vent, and the gap that air vent, air-vent are communicated with between light-source chamber two lobe spheroids forms heat dissipation channel jointly.

Further, described diffuser is installed on lamp socket, between described radiator, by connector or wire, is connected.

Further, described diffuser is comprised of symmetrically arranged two lobe diffusers, and wherein the upper and lower end of a lobe diffuser is equipped with positioning jack.

Further, described diffuser adopts glass, plastic material to make, and described lamp socket is that aluminum component, heat-conducting plastic part are made.

Further, described LED bulb is candle bulb, ball bubble.

The invention has the beneficial effects as follows: this kind of integral LED bulb, simple and reasonable, novel unique, and good heat dissipation effect.The present invention is a kind of important breakthrough and the innovation to current LED bulb structure, by the light source luminescent region at LED bulb, finding heat-dissipating space is heat dissipation channel, LED bulb heat radiation and the luminous two-part structure of LED bulb are carried out to organic combination, pass through in lamp body upper bottom perforate simultaneously, at the cross-ventilated passage of the inner formation of lamp body, preferably resolve the problem that LED bulb volume is little, heat-dissipating space is not enough, extended service life; And cost is low, easy to assembly, good looking appearance.
