Description
Technical field
The present invention relates to a kind of LED lamp, particularly relate to a kind of combined LED lamp that has radiator structure.
Background technology
The LED fluorescent lamp adopts the LED energy-conservation, that brightness is high, durable as its light source.Behind the light source of LED,, receive the general welcome of people, and traditional bulb decoration market is caused great threat because it has modern design, rich color, non-friable broken and advantages such as security that low pressure is used as fluorescent lamp.But existing LED fluorescent lamp process dispatch from the factory after, its shape generally all is changeless, range of exposures and irradiation brightness are all limited, the user can not do some variations to it according to the needs of oneself, uses comparatively trouble.
Simultaneously; The life-span of led light source and the operating temperature of node have closer getting in touch; At present the LED lamp has only 15%～25% electric energy to convert luminous energy in the course of the work; Remaining electric energy nearly all changes into heat energy, the temperature of LED lamp is raise, and every increase by 10 its reliabilities of degree of temperature will reduce half the.In great power LED, heat radiation is a big problem especially.Bad meeting directly causes the LED quick aging if dispel the heat, and stability reduces, and only adopts cooling base that the LED lamp is once dispelled the heat at present, and radiating efficiency is low, can't satisfy the demand of use.
Summary of the invention
Restricted in order to solve in the prior art LED light irradiation scope and irradiation brightness; Radiating effect is bad, and is rapidly aging, the problem that service life is short; The invention provides a kind of good heat dissipation effect; Long service life can be carried out assembly unit and dismounting with a plurality of LED lamp monomers easily, and the combined LED lamp that has radiator structure that can adjust according to the profile of the needs of the reality LED lamp after to assembly unit.
In order to address the above problem, the technical scheme that the present invention taked is:
A kind of combined LED lamp that has radiator structure; Comprise circuit board and led chip, some led chips are installed on circuit board, it is characterized in that: also comprise clamping plate, joint pin, heat pipe and radiator; Side at circuit board is provided with clamping plate; Opposite side at circuit board is provided with joint pin, and said joint pin can extend into the chucking that cooperatively interacts in the clamping plate, and said radiator is made up of the multilayer radiating fin side by side; One side of said heat pipe is installed in the bottom of circuit board, and the opposite side of heat pipe passes the multilayer radiating fin.
Aforesaid a kind of combined LED lamp that has radiator structure, it is characterized in that: said clamping plate are processed by elastomeric material.
Aforesaid a kind of combined LED lamp that has radiator structure, it is characterized in that: said clamping plate inboard is provided with projection, and said joint pin periphery is provided with the groove that is complementary with projection.
Aforesaid a kind of combined LED lamp that has radiator structure is characterized in that: said circuit board is by copper or aluminum and aluminium oxide or aluminium nitride material be combined into.
Aforesaid a kind of combined LED lamp that has radiator structure is characterized in that: the radiator that said multilayer radiating fin is formed is cylindrical or square.
The invention has the beneficial effects as follows: the present invention is dispelled the heat through heat pipe and external heat sink; The heat that distributes in the time of can high-powered LED lamp being worked is transmitted to heat pipe effectively; Heat pipe rely on its extremely strong heat-transfer capability with the heat high efficiency of transmission to radiating fin, the heat exchange through radiating fin and air distributes heat.Had the efficient conduction heat-sinking capability, prolonged the service life of LED lamp, reduced the loss of energy.The present invention simultaneously can carry out assembly unit through above-mentioned clamping plate and joint pin successively with a plurality of LED lamp monomers; And after assembly unit is accomplished; Can rotate around the rotating shaft of said clamping plate and joint pin formation between the adjacent LED lamp monomer, enlarge range of exposures, increase irradiation brightness.
Description of drawings
Fig. 1 is the combined LED modulated structure sketch map that the present invention has radiator structure.
The specific embodiment
As shown in Figure 1, a kind of combined LED lamp that has radiator structure comprises circuit board 1, led chip 2, clamping plate 3, joint pin 4, heat pipe 7 and radiator 8, and circuit board 1 can be by copper or aluminum and aluminium oxide or aluminium nitride material be combined into.Four led chips 2 are installed on circuit board 1, are provided with clamping plate 3 in a side of circuit board 1, said clamping plate 3 are processed by elastomeric material; Be provided with projection 5 in clamping plate 3 inboards; Opposite side at circuit board 1 is provided with joint pin 4, on the periphery of joint pin 4, is provided with the groove 6 that is complementary with projection 5; Clamping plate 3 can be clamped joint pin 4, clamp rearward projection 5 and can combine with groove 6.Square radiator 8 is made up of multilayer radiating fin 9 side by side, and a side of heat pipe 7 is installed in the bottom of circuit board 1, and the opposite side of heat pipe 7 passes multilayer radiating fin 9.
When reality is used; When the adjacent LED lamp connects; The clamping plate 3 of one of them can be clamped another joint pin 4, and the outside that makes clamping plate 3 be enclosed within said joint pin 4 forms movable rotation-shaft, and a plurality of like this LED lamp monomers carry out assembly unit through above-mentioned clamping plate 3 with joint pin 4 successively; And after assembly unit is accomplished, can rotate around said clamping plate 3 and the rotating shaft that joint pin 4 forms between the adjacent LED fluorescent lamp monomer.
LED lamp of the present invention dispels the heat through heat pipe 7 and square radiator 8 simultaneously, and heat pipe 7 relies on its extremely strong heat-transfer capability that the heat high efficiency of transmission is arrived radiating fin 9, through the heat exchange of radiating fin 9 with air heat is distributed.Had the efficient conduction heat-sinking capability, prolonged the service life of LED lamp, reduced the loss of energy.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
