Description

Split type LED bulb lamp lampshade and the full angle LED bulb lamp based on this lampshade
Technical field
The invention belongs to lighting technical field, relate to LED lighting engineering, relate in particular to a kind of LED bulb lamp.
Background technology
At present, the lighting being widely used remains self-ballasted fluorescent lamp (being commonly called as electricity-saving lamp), and it has the features such as light efficiency is high, light emitting anger is large, energy-conservation, enjoys user's approval.But its life-span is relatively short, the replacing of light fixture is with operational trouble to user on the one hand, and light fixture is changed the cost that has also increased user on the other hand, and for this reason, people are finding the life-span substitute products longer than service life of energy-saving lamp always.
Under above-mentioned background, LED lighting product arises at the historic moment, and wherein, shape and use habit are close to the LED bulb lamp of conventional incandescent, and market prospects are the best.On market, existing its structure of LED bulb lamp product generally as shown in Figure 1, 2, the main lampshade of being made by lamp holder, pedestal, light transmissive material, LED light source etc. form, wherein lamp holder is assemblied in pedestal lower end, in pedestal, be set to the driving power of LED light source power supply, the illuminator of LED light source is arranged on substrate, and substrate is assemblied in pedestal upper end.Lampshade lower ending opening and pedestal are mounted with, and LED light source is covered in to inside.
Based on this structural design, in order to guarantee the assembling of lampshade and substrate, substrate diameter must be less than the bore (otherwise substrate cannot pack lampshade into) of lampshade lower ending opening, and the maximum gauge of pedestal must be greater than and at least equals lampshade lower ending opening (otherwise pedestal and lampshade cannot assemble).Because the pedestal that end face is larger than substrate, gear, at substrate rear (lamp holder direction), has blocked the light that (to lamp holder direction) irradiates backward, so existing LED bulb lamp lighting angle is all less, even some is less than 180 °, exists very large illumination dead angle.
In addition, size of substrate is restricted, to LED light source, heat radiation brings certain negative effect, for this reason, the pedestal of existing LED bulb lamp generally comprises specially designed radiator structure, and this radiator portion generally all designs to obtain very large (much larger than lamp holder), to increase radiating effect, the complexity that this has not only increased base construction, has improved pedestal cost, has more strengthened illumination dead angle.Each developed country is all making great efforts to break through this technical bottleneck for this reason.
The technical problem that has illumination dead angle for LED bulb lamp, has two kinds of improvement schemes at present:
Scheme one: in bulb lamp design, a light-guiding pillar is set above aluminium base, the light that LED light source is sent, after reflection and refraction by light-guiding pillar, rearward penetrates, and then increase the lighting angle of bulb lamp;
Scheme two: improve LED light source, LED illuminator is integrated, light source is made to strip, along axis setting, to increase LED light source to the distance of pedestal, and then the lighting angle of increase bulb lamp, this type of bulb lamp lampshades that are similar to flare shape that adopt, are commonly called as candle lamp more on market.
Above-mentioned two schemes, has all increased lighting angle than original product, respectively has its pluses and minuses.But their power has limitation, the bulb lamp in scheme one, because it is arranged on pedestal upper end by aluminium base, cross-sectional area is limited, in order to meet its heat radiation and profile feature, increase product power, overall product volume be must strengthen thereupon, product aesthetics and relevance grade reduced.And scheme two, after increased power, its heat dissipation problem is restricting its development too, and general power is in 7W left and right.
