Abstract
The utility model relates to a light emitting diode (LED) lamp with a favorable heat-radiating effect, comprising a lamp holder connected with a power supply, a lamp shell, a lampshade, a plurality of LEDs and a circuit board, wherein the plurality of LEDs are arranged on the circuit board, a heat radiating fin is arranged in the lamp shell and connected with the circuit board, and the shell around the heat radiating fin is provided with a plurality of heat radiating holes. In the utility model, because the heat radiating fin is arranged in the lamp shell and can absorb the heat emitted by the plurality of LEDs and introduce heated air out of the lamp via the heat radiating holes, thus good heat conduction and cooling effects can be achieved, and the service life of the LED lamp is prolonged.
Description
Technical field
The utility model relates to a kind of LED light fixture, especially relates to a kind of LED light fixture with great heat radiation effect.
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.
As shown in Figure 1, be an existing LED light fixture, this light fixture comprises lamp holder 11, shell 12, reflecting piece 13, lampshade 14, Light-Emitting Diode 15 and circuit board 15.
But, this LED light fixture is owing to used a large amount of light emitting diode 15, a large amount of light emitting diodes 15 can distribute a large amount of heats, these heat accumulations get up and will damage even burn circuit board 15 to the circuit board 15 of light fixture, and are serious in influencing the service life of LED light fixture and the stability of operation.
The utility model content
The utility model has designed a kind of LED light fixture with great heat radiation effect, and the technical problem of its solution is that existing LED light fixture radiating effect is bad and have influence on the LED light fixture and use normally.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of LED light fixture with great heat radiation effect, comprise the lamp holder, shell, lampshade, a plurality of Light-Emitting Diode and the circuit board that are connected with power supply, described a plurality of Light-Emitting Diode is installed on the described circuit board, one radiating fin is set in described shell, described radiating fin is connected with described circuit board, offers a plurality of louvres on the shell around the described radiating fin.
Further, around described a plurality of Light-Emitting Diodes, be provided with the reflecting metal sheet.
Further, the outer surface at described a plurality of Light-Emitting Diodes is provided with one deck nano fluorescent bisque uniformly.
Further, described lampshade is sphere or spirality.
This LED light fixture with great heat radiation effect is compared with the common LED lamp tool, has following beneficial effect:
(1) the utility model is owing to be provided with a radiating fin in shell, this radiating fin can absorb the heat that a plurality of Light-Emitting Diodes come out, and by louvre hot-air is derived outside the light fixture, thereby can play good heat conduction and cooling-down effect, prolonged the service life of LED light fixture.
(2) the utility model is owing to the outer surface at described a plurality of Light-Emitting Diodes is provided with one deck nano fluorescent bisque uniformly, the light that this nano fluorescent bisque can make light emitting diode send is softer or strong, can reduce the quantity that LED uses, also just play the function that reduces the heat discharging simultaneously.

The specific embodiment
Below in conjunction with Fig. 2 and Fig. 3, the utility model is described further:
As shown in Figure 2, a kind of LED light fixture with great heat radiation effect, comprise the lamp holder 21, shell 22, lampshade 24, a plurality of Light-Emitting Diode 25 and the circuit board 26 that are connected with power supply, described a plurality of Light-Emitting Diode 25 is installed on the described circuit board 26, one radiating fin 27 is set in described shell 22, described radiating fin 27 is connected with described circuit board 26, offers a plurality of louvres 28 on the shell 22 around the described radiating fin 27.Because a radiating fin 27 is set in shell, this radiating fin 27 can absorb the heat that a plurality of Light-Emitting Diodes 25 come out, and by louvre 28 hot-air is derived outside the light fixture, thereby can play good heat conduction and cooling-down effect, prolonged the service life of LED light fixture.
Around described a plurality of Light-Emitting Diodes 25, be provided with reflecting metal sheet 23.This reflecting metal sheet 23 can be so that the brightness of light fixture be concentrated more and gathering.
Described lampshade 24 is sphere or spirality.Difform lampshade 24 can satisfy different customer demands.
As shown in Figure 3, the outer surface at described a plurality of Light-Emitting Diodes 25 is provided with one deck nano fluorescent bisque 29 uniformly.This nano fluorescent bisque 29 can be so that the light that light emitting diode 25 sends be softer or strong, thereby can reduce the quantity that LED uses, and also just plays the function that reduces the heat discharging simultaneously.
