Description
Technical field
The utility model relates to a kind of LED light fixture, especially relates to a kind of LED taper light fixture that disposes heat abstractor.
Background technology
LED (Light Emitting Diode), light emitting diode is a kind of solid-state semiconductor devices, it can directly be converted into light to electricity.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole, and the other end connects the positive pole of power supply, makes entire wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is a P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is a N-type semiconductor, mainly is electronics here.But when these two kinds of semiconductors couple together, just form a P-N knot between them.When electric current acted on this wafer by lead, electronics will be pushed to the P district, and electronics will send energy with the form of photon, the luminous principle of LED that Here it is then with hole-recombination in the P district.And the light wavelength color of light just is by the material decision that forms the P-N knot.
LED is directly had the following advantages as lighting: 1, the LED consumed energy reduces 80% with the incandescent lamp of light efficiency; 2, LED does not have poisonous metal mercury, can not pollute environment; 3, LED uses low-tension supply, and supply voltage is between 6-24V, and is different and different according to product, so it is a safer power supply of ratio use high voltage source, is specially adapted to public place and family and uses.
But when LED is used as light fixture, during especially as the light source of cylindricality light fixture, may there be heat dissipation problem and the uneven problem of light scattering.
The utility model content
The utility model has designed a kind of LED taper light fixture that disposes heat abstractor, and it has solved following technical problem: (1) has the not good problem of LED light fixture radiating effect now; (2) the existing uneven problem of LED light fixture light scattering.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of LED taper light fixture that disposes heat abstractor, comprise circuit board, a plurality of light emitting diode, Transparent lamp shade and heat abstractor, described a plurality of light emitting diode is arranged on the described circuit board, on described heat abstractor, offer the lamp installation groove of a taper, described a plurality of light emitting diode and described circuit board are placed in the described lamp installation groove, the outer surface of described heat abstractor is spiral-shaped radiating fin, has a helical form gas channel between adjacent two radiating fins.
Further, be provided with a diffusion tabula rasa between described a plurality of light emitting diode and the described Transparent lamp shade.
Further, the outer surface of described a plurality of light emitting diodes is provided with one deck nano fluorescent bisque uniformly.
The LED taper light fixture of this configuration heat abstractor is compared with the common LED light fixture, has following beneficial effect:
(1) heat abstractor in the utility model is owing to be spiral-shaped radiating fin at outer surface, there is a helical form gas channel between adjacent two radiating fins, the light fixture evolution of heat can be derived by the helical form gas channel, this heat abstractor plays good heat conduction and radiating effect, can prolong the service life of light fixture;
(2) the utility model is owing to be provided with a diffusion tabula rasa between a plurality of light emitting diodes and Transparent lamp shade, and the light that light emitting diode sends can more can satisfy the requirement of people's eyes so that the light dispersion effect is more even through behind this diffusion tabula rasa.
(3) the utility model is owing to the outer surface at a plurality of light emitting diodes applies one deck nano fluorescent bisque uniformly, the light that this nano fluorescent bisque can make light emitting diode send is softer or strong, also can reduce the quantity that LED uses simultaneously to satisfy different lighting demands.
