Description

The high power LED electronic lamp of combined type polar heat radiation

Technical field

The utility model relates to a kind of lighting apparatus, specifically a kind of high power LED electronic lamp of combined type polar heat radiation.

Background technology

The world at current energy scarcity, people seek alternative energy source or exploitation energy-conserving product in every field, eliminated first generation light source incandescent lamp the field of illuminating lamps people, generally adopt energy-conservation fluorescent lamp and glow lamp, but the energy-saving lamp of fluorescent lamp and glow lamp series still be unable to do without heat filament and ballast, exist maximum deficiency to be to use the life-span short, reflect generally after the user uses that economize on electricity does not save money.Further in short supply along with world energy sources, people's power consumption that begins one's study is littler, the LED luminous tube of longer service life is as emerging lighting source, the velocitron of high-power light-emitting pipe has begun to be applied at some lighting fields, indicator lamp such as automobile, flashlight also has the street lamp or the warning lamp of the power of some, but the power of the LED luminous tube of prior art does not far reach the requirement of big occasion illumination, large-power lamp is all combined by many luminous tube arrays and reaches power demand and illumination generally speaking, but the heat that many luminous tube array combination backs of prior art produce directly has influence on the luminous efficiency and the service life of light fixture.Therefore, manage to reduce the caloric value of pipe and the heat that will produce as early as possible dissipates, just will make light fixture reach the biggest problem that thermal balance has become this application technology being no more than under the prerequisite that pipe allows junction temperature.

Many luminous tube array combinations are to be combined into little unit with two kinds of forms of serial or parallel connection earlier, connect according to the unit parallel connection of a plurality of series connection of big young pathbreaker of power demand again or with the unit of a plurality of parallel connections then, these two kinds group modes in theory all are fine again.

But, because internal resistance and some parameter of every luminous tube are not quite similar, the voltage drop of the unit of series connection form on every pipe after the energising is different, power difference when so just having caused every pipe work and then temperature rise difference, the luminous tube mode that is connected in series has caused very big difficulty for the heat radiation of pipe on manufacturing process, have to use nonmetal Heat Conduction Material and realize heat radiation, but the low heat conductivity of nonmetallic materials greatly reduces the radiating efficiency of pipe again, because heat dissipation problem really is not resolved, the operating current of LED luminous tube can't reach optimum state, it is the highest that lamp illuminance just can't reach, the work down of big electric current, the heat of LED luminous tube inside can increase the resistance of LED luminous tube, the increase of resistance can strengthen the heating of LED luminous tube conversely again and then cause the LED luminous tube to burn out, thereby, also there is not the real sub-lamp of desirable electric consumption on lighting to be applied at present.

Summary of the invention

The utility model provides the high power LED electronic lamp of combined type polar heat radiation a kind of simple in structure, with low cost.

Velocitron of the present utility model is realized in the following manner, the structure of this electronics is by the LED luminous tube, reflection shield, fin, circuit board and matrix lamp socket, fin is as the cathode conductor of LED luminous tube, insulating circuit board is as the negative pole electric conductor of LED luminous tube, insulating circuit board is embedded in the upper surface of fin, fin is side by side parallel or form hexagonal configuration and be arranged on the matrix lamp socket, have the anodal jack and the negative pole small opening of the anodal pin of grafting LED luminous tube on the fin, the positive pole of LED luminous tube and negative pole are inserted in respectively among the anodal jack and negative pole small opening of fin, the upper surface of fin is provided with the insulating circuit board slot, have the jack that connects negative pole on the insulating circuit board, the negative pole pin of LED luminous tube is inserted among the jack of insulating circuit board, the jack that connects negative pole on the insulating circuit board is positioned at the centre of fin negative pole small opening, and reflection shield is arranged on the periphery of LED luminous tube.

The beneficial effects of the utility model are: reasonable in design, good heat dissipation effect, can make the operating current of LED luminous tube in the light fixture adjust to optimum state, thereby improved the illumination of LED luminous tube greatly, in order further to improve the illumination of LED luminous tube, also the periphery at each LED luminous tube is provided with reflection shield, with whole scatterings and reflex in the scope of regulation because of intersection causes the visible light of loss to concentrate, make secondary light-distribution more become reasonable.Reflection shield with reasonable cooperation of fin improved radiating effect greatly, improved the service life of light fixture simultaneously.Make energy-conservation LED luminous tube matrix light fixture replace the higher light fixture of existing power consumption to become a reality.From then on start a global lighting great revolution.
