Abstract

The utility model discloses a light emitting diode (LED) lamp, which comprises a printed circuit board (PCB) substrate and an LED arranged on the PCB substrate. The LED lamp further comprises a radiator connected with the PCB substrate. A radiation metal housing integrated with the radiator is arranged on the radiator and covered outside the LED, and is a reflective lampshade. Therefore, the reflective lampshade not only can reflect light rays, but also can function in heat conduction and radiation together with the radiator to dissipate heat produced by the LED to accelerate radiation speed, keep the temperature of the LED lamp at a relatively lower value, slow down optical attenuation and prolong the service life of the LED lamp.

Description

The LED lamp

Technical field

The utility model relates to the LED lighting technical field, particularly a kind of good heat dissipation effect and LED lamp simple in structure.

Background technology

LED (Light Emitting Diode, light emitting diode) is a kind of solid-state semiconductor devices, and 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 one " P-N knot " between them.When electric current acted on this wafer through 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 color of light wavelength decision light, by forming the decision of P-N knot material.

Yet the heat dissipation technology of LED lamp still is the problem that people are studying always, and the radiator heat-dissipation effect of existing LED lamp is all not so good, so that influences the service life of LED lamp.Therefore, how to design a kind of good heat dissipation effect, LED light fixture simple, that material usage is little rational in infrastructure is the technical problem that needs to be resolved hurrily in the industry.

Summary of the invention

The main purpose of the utility model provides the LED lamp that a kind of radiating effect is good, simple in structure, material usage is little, is intended to accelerate the radiating rate of LED lamp, improves the quality and the service life of LED lamp.

The utility model proposes a kind of LED lamp; Comprise the PCB substrate, be installed in the LED lamp pearl on the said PCB substrate; Also comprise the radiator that is connected with said PCB substrate; Said radiator be provided with one with the heat radiating metal shell of its integrated molding, said heat radiating metal jacket is outside said LED lamp pearl, said heat radiating metal shell is a lampshade.Said lampshade not only can reflection ray, can also play heat conduction and heat radiation with said radiator, and the heat that LED lamp pearl is produced distributes.

Preferably, said radiator comprises a metal base plate, several vertically are arranged on the bonding jumper on this metal base plate, is not connected mutually between the said bonding jumper.

Preferably, said bonding jumper and said metal base plate integrated molding are made.

Preferably, said bonding jumper is cylindrical or prismatic structures.

Preferably, said radiator is that aluminium, copper or iron are processed.

Preferably, also comprise the fixed mount that is connected with said radiator or lampshade, said fixed mount is installed in the outside of said radiator and said lampshade.

Preferably; Said PCB substrate is an aluminum PCB substrate, and aluminium has good heat-conducting, and its heat conductivility is bigger 3 times than iron; So can increase the capacity of heat transmission of PCB substrate with aluminium as the raw material of PCB substrate, the heat that LED lamp pearl is produced when luminous passes rapidly.

The utility model LED lamp as its lampshade, and is arranged on the heat radiating metal shell on the radiator, with the radiator integrated molding, makes the lampshade not only can reflection ray, can also play heat conduction and heat radiation with said radiator.The heat that LED lamp pearl comes out when luminous passes to lampshade and radiator through the PCB substrate; Together heat is distributed by radiator and lampshade, accelerate radiating rate, make the temperature of LED lamp remain on a relatively low value; The light decay that slows down prolongs service life of LED lamp.

Fig. 2 is the embodiment normal section sketch map of the utility model LED lamp.

The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.

The specific embodiment

Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

See figures.1.and.2, propose an embodiment of the LED lamp of the utility model, this LED lamp comprises PCB substrate 30, is installed in the LED lamp pearl on the said PCB substrate 30, also comprises the radiator 10 that is connected with said PCB substrate 30.Said radiator 10 be provided with one with the heat radiating metal shell 20 of its integrated molding, said heat radiating metal shell 20 covers on outside the said LED lamp pearl, said heat radiating metal shell 20 is a lampshade.Therefore said lampshade not only can reflection ray, can also play heat conduction and heat radiation with said radiator 10, and the heat that LED lamp pearl is produced distributes, and accelerates radiating rate.

Said radiator 10 is processed for aluminium, copper or iron; Comprise that a metal base plate and several vertically are arranged on the bonding jumper 101 on this metal base plate; Said bonding jumper 101 is cylindrical or prismatic structures, is separated with certain distance between the said bonding jumper 101, is not connected mutually.Said bonding jumper 101 is made with said metal base plate integrated molding, makes manufacturing process simpler.This LED lamp also comprises the fixed mount 40 that is connected with said radiator 10 or said heat radiating metal shell 20, and said fixed mount 40 is installed in the outside of said radiator 10 and said heat radiating metal shell 20, in order to fixed heat sink 10.

Said PCB substrate 30 is an aluminum PCB substrate; Aluminium has good heat-conducting; Its heat conductivility is bigger 3 times than iron, so can increase the capacity of heat transmission of PCB substrate 30 with aluminium as the raw material of PCB substrate 30, the heat that LED lamp pearl is produced when luminous passes rapidly.

Said PCB substrate 30 is installed in the position that said radiator 10 links to each other with said heat radiating metal shell 20; Be connected in aggregates with said radiator 10; During the luminous generation great amount of heat of LED lamp pearl, PCB substrate 30 can be rapidly with heat transferred radiator 10 and said heat radiating metal shell 20 that can heat conduction and heat radiation, together heat is distributed by radiator 10 and heat radiating metal shell 20; Accelerate radiating rate; Make the temperature of LED lamp remain on a relatively low value, the light decay that slows down, the service life of prolongation LED lamp.
