The radiating fin is arranged in the housing and adopts an integral structure with the housing, therefore, the heat emitted by the light emitting diodes can be absorbed to the utmost extent and can be carried away by air with lower temperature, the good heat conducting effect and the temperature reducing effect can be further achieved, and the service life of the LED lamp is prolonged.

Description

A kind of LED light fixture with radiating fin

Technical field

The utility model relates to a kind of LED light fixture, especially relates to a kind of LED light fixture with radiating fin.

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 radiating fin, 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 radiating fin, 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, also comprise a radiating fin, described radiating fin is the hollow cylinder body structure, described radiating fin is enclosed within on the described shell, and the open circles diameter in the described radiating fin is identical with the diameter of described shell.

Further, described radiating fin and described shell are integral piece.

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 radiating fin 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 and described shell are integral piece, therefore can absorb the heat that light emitting diode sends to greatest extent, and these heats can be taken away by the lower air of temperature, thereby can play good heat conduction and cooling-down effect, prolong 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 to Fig. 4, the utility model is described further:

As shown in Figure 2, a kind of LED light fixture with radiating fin comprises 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, and described a plurality of Light-Emitting Diodes 25 are installed on the described circuit board 26.In addition, also comprise a radiating fin 27, described radiating fin 27 is the hollow cylinder body structure.As shown in Figure 3, described radiating fin 27 is enclosed within on the described shell 22, and the open circles diameter in the described radiating fin 27 is identical with the diameter of described shell 22.Thereby this radiating fin 27 can be enclosed within on the shell 22 closely, and fully contacts with shell 22.Perhaps, can make described radiating fin 27 and described shell 22 and be integral piece.This radiating fin 27 is an integral piece with described shell 22, therefore can absorb the heat that light emitting diode 25 sends to greatest extent, and these heats can be taken away by the lower air of temperature, thereby can play good heat conduction and cooling-down effect, have prolonged the service life of LED light fixture.
