Background technique
With the maturation of China's lighting engineering, various downlights, shot-light are quickly grown, and the downlight of traditional technology is mainly by lamp
Seat, the light source that is fixed in lamp holder, although can satisfy use demand to a certain extent, due to lamp holder space compared with
It is small, and light source can generate certain heat when in use, so powerful light source can not be arranged to because its heat can not and
When disperse to will affect the stability in use and service life of light source, applicability and practicability are restricted.
Summary of the invention
Reasonable and perfect heat-dissipating the downlight with radiator structure the object of the present invention is to provide a kind of structure setting.
The technical solution for realizing the object of the invention is a kind of downlight with radiator structure, including annulus lamp plate, cylindrical shape
Lamp holder and the lighting source being arranged in the cylinder-shaped lamp holder, have in the cylinder-shaped lamp holder and are connected with the lighting source
The radiator connect is additionally provided with small-sized fans in the cylinder-shaped lamp holder, and the small-sized fans are in the top of radiator and institute
It is fixed on a heat sink by screw rod to state small-sized fans, round web plate is additionally provided with above the small-sized fans, in the circle
Fixing annulus is additionally provided with above shape web plate, the outer diameter for fixing annulus is greater than the internal diameter of cylinder-shaped lamp holder.
It is additionally provided with torus in the bottom end of the cylinder-shaped lamp holder, the diameter both ends of the torus are fixed by screws in
On the bottom surface of cylinder-shaped lamp holder, the annular groove of top surface opening is equipped on the inner wall of the annulus lamp plate and in the annular groove
Annular pressing plate is arranged at top, and the torus is between annular groove and annular pressing plate.
Radiating fin is uniformly fixed on the outer wall of the cylinder-shaped lamp holder.
It is set on the outer wall of the annulus lamp plate there are two buckle, described two buckles are separately fixed at the straight of round lamp board
It diameter both ends and snaps through shaft and is connected on the outer wall of annulus lamp plate.
The present invention has the effect of positive：Structure setting of the invention is reasonable, and one is increased in cylinder-shaped lamp holder
Small-sized fans and it is additionally provided with round web plate above, so as to greatly improve the heat dissipation performance of cylinder-shaped lamp holder, so can
To greatly improve the power of lighting source, be conducive to improve its whole stability in use and service life, strong applicability and reality
It is good with property.
Detailed description of the invention
In order to make the content of the present invention more clearly understood, right below according to specific embodiment and in conjunction with attached drawing
The present invention is described in further detail, wherein：
Fig. 1 is external structure of the invention；
Fig. 2 is the cut-away view of A-A in Fig. 1.
Specific embodiment
(embodiment 1)
Fig. 1 and Fig. 2 shows a kind of specific embodiment of the invention, and wherein Fig. 1 is external structure of the invention；Figure
2 be the cut-away view of A-A in Fig. 1.
See Fig. 1 and Fig. 2, a kind of downlight with radiator structure, including annulus lamp plate 1, cylinder-shaped lamp holder 2 and setting are in institute
The lighting source 3 in cylinder-shaped lamp holder 2 is stated, has the radiator being connected with the lighting source 3 in the cylinder-shaped lamp holder 2
4, it is additionally provided with small-sized fans 5 in the cylinder-shaped lamp holder 2, the small-sized fans 5 are in the top of radiator 4 and described small-sized
Fan 5 is fixed on radiator 4 by screw rod 6, round web plate 7 is additionally provided in the top of the small-sized fans 5, in the circle
The top of web plate 7, which is additionally provided with, fixes annulus 8, and the outer diameter for fixing annulus is greater than the internal diameter of cylinder-shaped lamp holder.When in use will
Fixing annulus, which is caught in cylinder-shaped lamp holder, fixes round web plate.
It is additionally provided with torus 9 in the bottom end of the cylinder-shaped lamp holder 2, the diameter both ends of the torus 9 pass through screw 10
It is fixed on the bottom surface of cylinder-shaped lamp holder 2, the annular groove of top surface opening 10 is equipped on the inner wall of the annulus lamp plate 1 and in institute
Stating at the top of annular groove has annular pressing plate 11, and the torus is between annular groove and annular pressing plate.So as to so that cylinder
Shape lamp holder and torus rotate in annulus lamp plate and cylinder-shaped lamp holder can rotate one angle of inclination centered on screw,
So as to adjust irradiating angle and the rotary irradiation direction of downlight as needed.
Radiating fin 12 is uniformly fixed on the outer wall of the cylinder-shaped lamp holder.
It is set on the outer wall of the annulus lamp plate there are two buckle 13, described two buckles are separately fixed at round lamp board
It diameter both ends and snaps through shaft 14 and is connected on the outer wall of annulus lamp plate.
Structure setting of the invention is reasonable, and a small-sized fans are increased in cylinder-shaped lamp holder and are also set above
There is round web plate, so as to greatly improve the heat dissipation performance of cylinder-shaped lamp holder, so the function of lighting source can be greatly improved
