Description

A kind of household LED electricity-saving lamp

Affiliated technical field

The utility model relates to a kind of electricity-saving lamp, relates in particular to a kind of household LED electricity-saving lamp.

Background technology

China is one of the most serious country of world's natural resources waste, and rank is the 56th in the country that 59 in the United Nations accepts to investigate, and energy use efficiency only is 26.9% of the U.S., 11.5% of Japan, therefore, advance energy-saving and emission-reduction, put in the critical positions of China's state basic policy.The electricity-saving lamp made from the LED light emitting diode is than ordinary incandescent lamp power saving more than 90%, more than 50%, service life is up to more than 100,000 hours, and harmful elements such as not mercurous and sodium than common energy-saving lamp power saving, be the lighting of efficient energy-saving green environment protection, gain public acceptance and promote.But because the LED light emitting diode needs DC driven, therefore generally use Switching Power Supply or regulator rectifier circuit on the led electricity-saving lamp, when having increased non-electric consumption on lighting consumption, increased the caloric value of light fixture integral body again, power consumption efficiency is reduced, and the service life of having reduced light emitting diode, the manufacturing cost of LED electricity-saving lamp is improved, the selling price height is difficult to promote.Therefore be sought after a kind of simple in structurely on the market, caloric value is low, long service life, and also manufacturing cost and use cost are all low, the LED energy-saving lamp of being convenient to promote.

Summary of the invention

This novel purpose is according to the market demand, provides a kind of simple in structure, and caloric value is low, and long service life reduces production costs, the LED energy-saving lamp of being convenient to promote.This is by the following technical solutions novel in order to achieve the above object: be connected with insulator below the lamp holder, be fixed with upper shell below the insulator, bossed radiating wing above the upper shell, between upper shell and the lower house with being threaded, scribble heat-conducting silicone grease during connection, 73 light emitting diodes are housed on the plane of lower house, scribble heat-conducting silicone grease between light emitting diode and the lower house, the electrode of light emitting diode is welded on the interior wiring board of housing, 73 light emitting diode series connection connect, its rectification circuit is the bridge rectifier that 4 commutation diodes are formed, positive pole after the rectification is connected on the positive pole of light emitting diode behind capacitor filtering, the negative pole after the rectification is connected on the negative pole of light emitting diode through electric capacity.

This novel beneficial effect is: energy-conserving and environment-protective, do not pollute, and long service life, simple in structure, easy to manufacture, reduced production cost and use cost, be convenient to large-scale promotion.

Description of drawings:

Below further specify by drawings and Examples novel:

Fig. 1 is the upper shell of embodiment and the structural representation of lamp holder;

Fig. 2 is the overall structure schematic diagram of embodiment;

Fig. 3 is the part cross-sectional schematic of upper and lower casing;

Fig. 4 is the circuit diagram of embodiment;

Among the figure: 1, lamp holder; 2, insulator; 3, radiating wing; 4, upper shell; 5, light emitting diode; 6, lower house; 7, heat-conducting silicone grease; 8, heat-conducting silicone grease; 9, wiring board.

Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, lamp holder 1 is identical with the lamp holder of common bulb, be connected with insulator 2 below the lamp holder 1, be fixed with upper shell 4 below the insulator 2, bossed radiating wing 3 above the upper shell 4, upper shell 4 is cast the integrative-structure made from radiating wing 3 for aluminium, with being threaded, coats heat-conducting silicone grease 8 during connection between upper shell 4 and the lower house 6.A plurality of light emitting diodes 5 are housed on the lower house 6, scribble heat-conducting silicone grease 8 between light emitting diode and the lower house, the electrode of light emitting diode is welded on the interior wiring board 9 of housing.Light emitting diode belongs to cold light source, and caloric value own is very little, and heat is delivered on the lower house 6 through heat-conducting silicone grease 8, is delivered to then on upper shell 4 and the radiating wing 3 and dispels the heat.This novel circuit is very simple, imports 220 volts of electric mains, as shown in Figure 4, adopts 4 self-cooled commutation diode D1-D4 to form bridge rectifier.C1 is a high-frequency filter capacitor, consider the high frequency clutter that removes in the voltage, prolong the service life of light emitting diode, positive pole after the rectification is connected on the positive pole of light emitting diode D5 behind the C1 capacitor filtering, negative pole after the rectification is connected on the negative pole of light emitting diode D77 after capacitor C 1,73 light emitting diode D5-D77 are connected in series, about 3 volts of voltages on every the light emitting diode in series connection back.

This novel genus energy-conserving and environment-protective product does not pollute, and long service life is simple in structure, easy to manufacture, has reduced production cost and use cost, and applying of it benefited the nation and the people, and will produce bigger economic benefit and social benefit.
