Description
Technical field
The present invention relates to a kind of LED bulb lamp, especially relate to a kind of LED bulb lamp of high-cooling property.
Background technology
At present, realizing carbon reduction, green illumination cry surging period, incandescent lamp is eliminated just gradually, and the substitute is with the LED bulb lamp is the novel green lighting source of representative.
The key technical index of weighing the LED bulb lamp mainly is luminous flux, colour temperature, colour rendering etc., and the numerical value of luminous flux is closely related with the power that is consumed with the LED light efficiency.The LED bulb lamp is as the substitute products of incandescent lamp, and its appearance and size is limit by former incandescent lamp, therefore under same size, make the luminous flux of LED the highest, except the LED that selects high light efficiency for use, also must consider its best thermal diffusivity.
We know that under field conditions (factors), radiating mode mainly contains hot conduction, heat radiation and thermal convection current, and are best with the thermal convection current radiating effect especially.
With regard to LED bulb lamp radiator structure, the present invention has utilized " stack effect "." stack effect ", be meant indoor air along the space that vertical bank is arranged to rising or descending, cause air to add the phenomenon of strong convection.The generation of " stack effect "; Having shared Zhongting, vertical (smoke evacuation) air channel, the staircase etc. of ventilating to have similar " chimney characteristic "---promptly have from bottom to top in the building, structures (like water tower) of unobstructed free air space; Air (comprising flue gas) leans on the effect of density contrast; Spread or discharge the phenomenon of building very soon along passage, be " stack effect ".
In actual use, in order to reach good radiating effect, often adopt the mode that strengthens radiator surface area to reach thermal balance.Increase but the consequence of doing like this is the weight of radiator, too much consumed nonferrous materials.We know that from thermodynamics knowledge the air nature coefficient of heat transfer is 3～10, and the coefficient of heat transfer of gas forced convection is 20～100.We adopt the radiator structure of " stack effect ", just can reach under identical heat dispersion, have both reduced the use amount of metal material, have strengthened radiating effect again, thereby have satisfied the performance requirement of LED bulb lamp better.
Summary of the invention
The object of the invention is exactly the LED bulb lamp that a kind of efficient, power saving, long-life high-cooling property are provided in order to overcome the defective that above-mentioned prior art exists.
The object of the invention can be realized through following technical scheme:

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
As shown in Figure 1, a kind of LED bulb lamp of high-cooling property comprises lamp holder 1, working of plastics 2, aluminium shell 3, radiator 4, LED aluminium base 6, led light source 7, glass shell 8; Described working of plastics 2 is fixed on the lamp holder 1, and described aluminium shell 3, radiator 4 are fixed on working of plastics 2, and described led light source 7 is fixed on the LED aluminium base 6; Described LED aluminium base 6 is located in the glass shell 8; Described glass shell 8 is connected with aluminium shell 3, it is characterized in that described radiator is located at aluminium shell 3 inside; The surface is provided with airslide; Have pore on the described working of plastics 2, be provided with wind passage mouth between described glass shell 8 and the aluminium shell 3, described pore, airslide, wind passage mouth form convection channel.Described working of plastics 2 is fire-retardant perforate working of plastics.Described radiator 4 is the die casting aluminium radiator.
Form the heat radiation ditch on the surface of die casting aluminium radiator 4; The aluminium shell 3 that combined diameter is big slightly again in the outside of die casting aluminium radiator 4; Simultaneously on fire-retardant perforate working of plastics 2, leave air vent; The space of reserving with glass shell 8 places forms the passage of natural convection air, thereby forms " stack effect ", reaches the purpose of strengthening heat radiation.
When reality is used, no matter light-emitting area is down or up, aluminium shell 3 and the airslide 5 that radiator 4 forms naturally all can constitute " stack effect ", strengthen the radiating effect of bulb lamp.Therefore have the characteristics flexible, good heat dissipation effect of using.The air-flow trend is like Fig. 2, shown in Figure 3.
Fire-retardant perforate working of plastics 2 and wind passage mouth form the air vent of nature, and in the time of as if light-emitting area down, air-flow flows to fire-retardant perforate working of plastics 2 by wind passage mouth through inner aluminium shell 3 and the airslide that radiator 4 forms naturally; Otherwise in the time of as if light-emitting area up, then the air-flow trend is with aforementioned opposite.Therefore, this novel high-heat dissipation LED bulb lamp no matter light-emitting area towards how, all can realize " stack effect ", reaches the purpose of strengthening the heat radiation of LED bulb lamp in use.Simultaneously, aluminium shell 3 also can play good heat-radiation effect.
