Description

LED lighting structure-improved

Technical field

The utility model relates to a kind of LED lighting structure-improved, espespecially a kind ofly forms the polytropism LED light fixture of illumination functions on a large scale, and the structure of the heat sinking function of excellence when forming simultaneously the LED running.

Background technology

Light emitting diode is made of semi-conducting material, utilizes electronics in the semiconductor to be combined with electric hole and sends photon, uses the luminescence component that produces different frequency spectrum.According to the otherness of encapsulation pattern, light emitting diode can be divided into bulb type (Lamp LED), dot matrix digit type (Display LED) and SMD LED surface-mount device LED (SMD LED).

LED can only be toward the energising of direction, i.e. forward bias, and when electric current flows through, the electroluminescent effect that electronics and electric hole overlap within it and send monochromatic light, and the wavelength of light, color follow its semiconductor material kind that adopts relevant with the element impurity of infiltration.The LED light fixture has that power saving, efficient are high, the life-span is long, the advantage that conventional light source is beyond one's reach such as fast, the high reliability of cracky, switching speed not.In recent years, the development of light emitting diode is advanced by leaps and bounds, brightness constantly promotes, color is more diversified, cost also constantly descends, but has directive property during the light emitting diode irradiation, become one of shortcoming in the utilization, that is to say that the illuminating ray that light emitting diode produces has certain directionality, if light emitting diode is arranged in same plane, the light that produces concentrates on same direction mostly, can't obtain illuminating effect in a big way.

In addition, LED is except sending visible light, other energy all converts heat to and concentrates on the little chip, cause a focus (hot spot) that temperature is quite high, the luminous efficiency of the higher then LED of temperature crystal grain is poorer, this is another distinct disadvantage of LED lamp, so must see through the heat radiation improving luminous efficiency, avoids simultaneously LED to burn.

Early stage LED lighting is to contain the lamp socket inner surface of setting big or small transparent lamp case one to assemble the circuit board of a circle, many light emitting diodes are set so that illumination to be provided on circuit board, but because most LEDs are located on the conplane circuit board, the light that produces concentrates on same direction mostly, thereby can't obtain illuminating effect in a big way.

At this point, TaiWan, China new patent No. 100202259 " upright tubular type LED bulb " can be installed on the circuit board of vertical type with various angle and direction most LEDs, then the circuit board that this is contained such as above-mentioned structure is installed in the glass tube, and plug the glass tube of the inner led circuit plate of most Zhi Hanyou at same lamp socket, see through this mode to strengthen the illumination functions of LED light fixture.But this kind LED bulb structure is located at most LED envelopes in the fluorescent tube, and radiator structure in the sky is just undesirable first.TaiWan, China new patent No. 099208601 " illumination of multi-direction LED lamp " is that most LED are installed on the internal circuit board of vertical type with various angle and direction equally, then with the most LED of a lampshade involution and circuit board, face equally the problem of radiator structure.

TaiWan, China new patent No. 099210936 " the LED illuminating lamp with high-effect radiator " then uses at this type of LED illuminating lamp and comprises the heat-sink unit that is comprised of several dissipation fins and louvre, and the fan blade that is driven by motor, the complicated integral structure manufacturing cost is high, also more expends the energy simultaneously and uneconomical.
