Description
Technical field
The utility model relates to a kind of lighting device, specifically refers to a kind of LED projecting lamp.
Background technology
Can along with sustained economic growth, demand for energy be increasing, in energy today of shortage day by day, lay in ample stocks of the energy and save and utilize the energy that very great meaning is arranged.Therefore, energy-conserving product has wide market prospects, and LED is called as green light source, has the characteristics of energy-conserving and environment-protective.
In order to obtain better illuminating effect, general projecting lamp all can arrange fixture, by fixture projecting lamp is fixed on desired location, and the lighting source of projecting lamp can from suitable position irradiation, be thrown light in the hope of better obtaining.But, nowadays the lamp socket of most of projecting lamps all adopts fixed structure, can not rotate after installing, poor practicability, simultaneously, projecting lamp long meeting service time produces amount of heat, overheated meeting burns out the various components and parts of projecting lamp inside, cause whole projecting lamp to damage, so the heat radiation of projecting lamp also is a problem.
The utility model content
Problem to be solved in the utility model provides a kind of LED projecting lamp, has solved in the past that the LED projecting lamp can not rotate on a large scale, the problem of poor radiation.
The technical scheme that the utility model provides is: a kind of LED projecting lamp, comprise the lamp cylinder, the lamp cylinder is the barrel shaped structure of the little and inner hollow of the large end of an end, the outer face of large end is provided with external screw thread, the lamp cylinder of small end forms several annular thin plates, thin plate is connected with the lamp cylinder by connecting plate, form the heat dissipation channel of several and lamp cylinder internal communication between the thin plate, outer face, lamp cylinder middle part also is connected with square contiguous block, in lamp cylinder inside circuit board is installed successively from the inside to surface, light source board, light transmission piece, outermost end is equipped with end cap, and gyroaxis top is connected with connecting plate, and the bottom connects lamp socket.
Described end cap front end inner surface is provided with a ring shape platform.The inner light transmission piece of chucking when ring-shaped platform is used for screwing.
Described light source board is provided with the deep hole of several depressions, and LED SMD lamp pearl is installed in the deep hole.According to using the required deep hole quantity that arranges.
Described gyroaxis is cylindrical, and the upper surface center position has vertical draw-in groove, and the outer face of gyroaxis also has the tapped through hole perpendicular to draw-in groove, and revolution shaft lower end face center position also has screwed hole.Draw-in groove is used for laying connecting plate, and screw passes tapped through hole contiguous block is connected in the draw-in groove on the gyroaxis, uses when the screwed hole of lower surface is used for fixed lamp-socket.
Described contiguous block is provided with the tapped through hole that is complementary with the gyroaxis tapped through hole.
Described lamp socket is rounded, and its circumferential end surfaces is evenly distributed with four tapped through holes, and the lamp socket centre position also has vertical through hole.
The utility model has the advantage of: this LED projecting lamp of the utility model design not only can rotate on a large scale, and thermal diffusivity is good.

Fig. 2 is structural representation of the present utility model.
Label among the figure is expressed as respectively: 1, end cap; 2, light transmission piece; 3, light source board; 4, circuit board; 5, lamp cylinder; 6, thin plate; 7, connecting plate; 8, contiguous block; 9, gyroaxis; 10, lamp socket.
The specific embodiment
Embodiment 1
1. referring to Fig. 1, a kind of LED projecting lamp, comprise lamp cylinder 5, lamp cylinder 5 is the barrel shaped structure of the little and inner hollow of the large end of an end, the outer face of large end is provided with external screw thread, lamp cylinder 5 cuttings of small end form several annular thin plates 6, thin plate 6 is connected with lamp cylinder 5 by connecting plate 7, form the heat dissipation channel of several and lamp cylinder 5 internal communication between the thin plate 6, outer face, lamp cylinder 5 middle part also is connected with square contiguous block 8, in lamp cylinder 5 inside circuit board 4 is installed successively from the inside to surface, light source board 3, light transmission piece 2, outermost end are equipped with end cap 1, gyroaxis 9 tops are connected with connecting plate 8, and the bottom connects lamp socket 10.
Above-mentioned end cap 1 front end inner surface is provided with a ring shape platform.
Above-mentioned light source board 3 is provided with the deep hole of several depressions, and LED SMD lamp pearl is installed in the deep hole.
Above-mentioned gyroaxis 9 is cylindrical, and the upper surface center position has vertical draw-in groove, and the outer face of gyroaxis 9 also has the tapped through hole perpendicular to draw-in groove, and gyroaxis 9 lower surface center positions also have screwed hole.
Above-mentioned contiguous block 8 is provided with the tapped through hole that is complementary with gyroaxis 9 tapped through holes.
Above-mentioned lamp socket 10 is rounded, and its circumferential end surfaces is evenly distributed with four tapped through holes, and lamp socket 10 centre positions also have vertical through hole.
During installation, first light transmission piece 2, light source board 3, circuit board 4 are positioned in the lamp cylinder 5 successively, outermost end is tightened with end cap 1, again contiguous block 8 is positioned in the draw-in groove of gyroaxis 9, utilize screw that the two is connected, from below to up lamp socket 10 is connected connection with gyroaxis by screw at last, with hold-down screw lamp socket 10 is fixed on desired location at last and gets final product.
