Description

A kind of high-heat-dispersion LED lamp

Technical field

The utility model relates to the LED lighting, is specifically related to the improved LED modulated structure of thermal diffusivity and light path.

Background technology

Mention illumination, people can expect those motley various light fixtures in the lamp store at once.Although coming in every shape of these light fixtures, the core of its illumination--bulb mainly contain three kinds in fact: incandescent lamp and fluorescent lamp, gas-discharge lamp.But, this general layout will change soon because lighting field a nova--light emitting diode bulb is moving towards the practicability stage.

LED (Light Emitting Diode, light emitting diode) is a kind of solid-state semiconductor devices that can electric energy be converted into visible light, and it can directly be converted into light to electricity.Because the advantage of LED lighting engineering has been developed the novel light-emitting diode bulb that is used to throw light on recently.This bulb has efficient height, long characteristics of life-span, can use continuously 100,000 hours, than long 100 times of ordinary incandescent lamp bubble.In the coming years, this LED bulb becomes the main product of illumination of future generation probably.

Existing LED bulb is that profile is similar to incandescent light bulb, but its structure is different fully, generally is to adopt following structure: include the screw socket of light bulb base or the lamp socket of bayonet socket; Be arranged at the led circuit plate in the lamp socket; Socket fixed heat sink on the lamp socket is placed a LED lamp plate on the radiator, the LED lamp plate generally adopts a plurality of LED that distribute on the circular substrate to form; The top that lies against radiator is then fixed; The fixing back of lampshade socket that the lampshade of the fixing dome-type of socket again on the radiator then, radiator generally are made into the latter half and the dome-type of globular bulb forms the profile of incandescent light bulb.

The weak point that existing this LED bulb structure exists is: 1) thermal diffusivity of LED lamp plate is not good, influences service life easily; 2) the LED lamp plate is through the bright dipping poor effect behind the lampshade of dome-type; 3) structural design is reasonable inadequately, causes inconvenient installation sharp, not quick.

The utility model content

The utility model technical problem to be solved is: overcome the existing not good problem of LED bulb heat radiation property 1..2. overcome the existing not good problem of LED lampshade light extraction efficiency.3. optimize each modular construction, produce installation effectiveness to improve.

In order to solve the problems of the technologies described above, the utility model adopts following concrete technical scheme:

A kind of high-heat-dispersion LED lamp comprises the light bulb base lamp holder is set, and is provided with the LED power supply circuit board in the lamp holder, fixing radiator of socket on the lamp holder, and the radiator upper surface is provided with the LED lamp plate, fixing lampshade of socket again on the radiator.Wherein, described radiator is bowl-shape shell mechanism, and also outwards stretching on the bowl-shape shell forms a plurality of radial radiating fins that are arranged on the shell, has a boss in the bowl, an earlier fixing conducting strip on the boss, fixing more described LED lamp plate on the conducting strip; Described lampshade is made up of the outer buckle closure of cyclic adapting piece, lens and ring-type, and is fixed on the rim of a bowl of described radiator through the screw socket.Radiator and combination fin through bowl structure and band radiating fin and boss can two kinds of approach be conducted heat, realize two-way heat conduction, can improve the life-span of LED lamp; Use the lampshade that increases the band lens that LED light is handled simultaneously, utilize the refraction and the principle of reflection of light, can do effective utilization to the light of LED product more, improve the light efficiency of whole lamp.

Further; Described lamp holder is socket-connected with the lamp holder adapter sleeve by screw socket cover seat 1 and forms; Screw socket cover seat screws on the screwed pipe that is socketed on lamp holder adapter sleeve lower end; Be provided with the led circuit plate in the lamp holder adapter sleeve, and in lamp holder adapter sleeve upper port cover unification plate, then more described radiator muff-joint is connected on the cylindrical outer wall of upper end of lamp holder adapter sleeve.Overlap the structure that seat and lamp holder adapter sleeve socket He Gai and middle plate are formed lamp holder through screw socket, not only install easily, also be beneficial to simultaneously the led circuit plate in the lamp holder is changed maintenance.

Further; Have a location in described on the plate and use projection; Have with the consistent location of said projection profile and use slotted eye on the boss in the described radiator, on the described fin with on the described LED lamp plate, on the boss in the described radiator, on the described fin and the projection on the plate and position cooperation in described of the slotted eye cutting ferrule on the described LED lamp plate.Through cooperating of location notch hole on the boss in locating convex block on the middle plate and the radiator, on the fin, on the LED lamp plate, can realize quick location and installation, improve and make efficiency of assembling.

Further; On the boss in described on the plate, in the described radiator, have the sealed screw of using on the described fin and on the described LED lamp plate, realize being fixedly connected of described LED lamp plate, fin, radiator and middle plate through self-tapping screw.Fix through screw, can be fixedly connected simple and reliablely, accomplish and install.

Further, described radiator uses is that 1070 aluminium sheet is processed.

The utility model adopts said structure, compares with existing LED bulb to have following advantage:

1) on the basis of original scheme, on bowl-shape radiator, increased boss and radiating fin, combined fin again, so just can have been conducted the heat that the LED wick produces to heat through two kinds of approach.Owing to can in time conduct the heat that the LED wick produces, can improve the life-span of lamp with the lamp of power; Secondly with the radiator of spline structure owing to can shed heat, can improve the power of LED lamp, increase benefit;

2) existing radiator generally is the die casting aluminium, its thermal conductivity factor about 97, and also the product of working it out is heavier; And the present radiator of the utility model uses is that 1070 aluminium sheet is processed, and the thermal conductivity factor of this kind material is about 267, and causes entire product low weight;

3) existing dome-type transparent lamp shade is replaced to by what the outer buckle closure of cyclic adapting piece, lens and ring-type was formed and can repair the lampshade of adjustment to LED bright dipping light path; Utilize the refraction and the principle of reflection of light; Can do effective utilization to the light of LED product more, improve the light efficiency of whole lamp;

4) owing to there is boss to do support, heat-conducting plate and radiator assembling deflection can not occur to fin when mounted, and it is more even to distribute when light sends like this;

5) through on the boss in locating convex block on the middle plate and the radiator, location notch hole cooperates on the fin, on the LED lamp plate; Can realize quick location and installation, assemble fairly simplely, quick, like this production efficiency can be provided; Practice thrift cost, improve the market competitiveness of lamp.
