As shown in Figure 3, cooling base 10 can utilize the mode of aluminium extruded type (Aluminum Extrusion) to be made, the material that is cooling base 10 is an aluminium, at this only for illustrating, do not limit to application category of the present utility model with this, and be provided with accommodation space 11 and fixed part 12 at cooling base 10, convex with two inclined planes 111 in the bottom of accommodation space 11, inclined plane 111 is the bottom center projectioies from accommodation space 11, be higher than the bottom of accommodation space with the bottom center that forms accommodation space, and present towards two different inclined planes 111.
And the fixed part 12 of cooling base 10 is to run through the outside left and right sides that cooling base 10 is arranged at accommodation space 11, the inclined plane that the bottom was convexly equipped with 111 of accommodation space 11 is the usefulness that is used to be provided with the circuit board 20 with a plurality of light emitting diodes 21, and because inclined plane 111 presents towards different, therefore, be arranged on the inclined plane 111 20 of circuit boards towards direction also present different towards, fixed part 12 is to be used for lampshade 40 is fastened on cooling base 10.
As shown in the figure, the outer shape of cooling base 10 is to present trapezoidal shape, drawing is only for illustrating, do not limit to application category of the present utility model with this, the outer shape of cooling base 10 also can present semicircle arcuation or other geometry, then, the outer shape with cooling base that drawing is illustrated 10 is that trapezoidal shape describes.
On the trapezoidal shape surface of cooling base 10, more be provided with a plurality of radiating fins 13, can in making the process of cooling base 10, aluminium extruded type extrude a plurality of radiating fins 13 in the lump, can increase the area of dissipation of cooling base 10 by cooling base 10 outside set radiating fins 13, can increase the radiating efficiency of cooling base 10, so as to heat energy dissipation in addition with the light emitting diode on the circuit board 20 21 produced.
Each circuit board 20 is provided with at least one light emitting diode 21, and each circuit board 20 is directly to be arranged on the inclined plane 111 of corresponding accommodation space 11, make the light emitting diode 21 on each circuit board 20 can directly touch cooling base 10, the heat energy that cooling base 10 promptly can directly be produced the light emitting diode on the circuit board 20 21 is absorbed, and passes through the set radiating fin 13 in cooling base 10 outsides with heat energy dissipation.
And, be electrically connected with two respectively each circuit board 20 both sides (being the side that cooling base 10 is provided with fixed part 12) and electrically connect element 30, promptly electrically connecting elements 30 with two of side forms with different circuit board 20 respectively and electrically connects, electrically connecting element 30 is the usefulness that forms electric connection with outside lamp socket (not illustrating among the figure), by outside lamp socket so that the electrical polarity of light emitting diode 21 on the circuit board 20 to be provided, the electric connection element that electrically connects when element 30 is general fluorescent tube and generally normal lighting equipment is with electric connection is a same size, so that make the utility model lamp tube structure of light-emitting diode electrically connect compatible use with general daylight lamp holder.
As shown in the figure, circuit board 20 is with screw-in version by retaining element 61, circuit board 20 is fixed on the inclined plane 111 of accommodation space 11, the mode that circuit board 20 is fixed in the accommodation space 11 of cooling base 10 is not restricted to by screwing togather fixed form, anyly can reach fixed form, for example: the mode that is fixed, the mode etc. that is fastened, all can be included among the utility model fixed form, do not limit to application category of the present utility model with this.
Then, please also refer to Fig. 4 and shown in Figure 5, Fig. 4 is the utility model lamp tube structure of light-emitting diode cooling base element stereogram; Fig. 5 is the utility model lamp tube structure of light-emitting diode profile.
The inclined plane 111 that is convexly equipped with in the bottom of cooling base 10 accommodation spaces 11, the with respect to the horizontal plane set angle in inclined plane 111 is spent between 60 degree between 30, set inclined plane 111 is two in the bottom of cooling base 10 accommodation spaces 11 as shown in the figure, in graphic only for illustrating, do not limit to application category of the present utility model with this, circuit board 20 with a plurality of light emitting diodes 21 is set respectively on two inclined planes 111, owing on two different inclined planes 111, circuit board 20 is set respectively, therefore, by the increase of light emitting diode 21, can increase the luminosity of light-emitting diode lamp tube.
In addition, more because the inclined plane 111 that is convexly equipped with in the bottom of cooling base 10 accommodation spaces 11, the circuit board 20 that can will be disposed on the inclined plane 111 is faced different directions, can be so that the light emitting diode 21 of circuit board 20 has different light emitting regions and (please refer to shown in Figure 5 on two different inclined planes 111, dotted portion is the signal of lamp tube structure of light-emitting diode light emitting region among the figure), promptly can increase the light emitting region of light-emitting diode lamp tube integral body, when throwing light on a large scale, when adopting light-emitting diode lamp tube of the present utility model, because the scope of being shone of single light-emitting diode lamp tube is bigger, therefore, can adopt less light-emitting diode lamp tube promptly can reach identical effect, promptly can effectively reduce use cost.
Because lampshade 40 presents convex-concave surface, during the convex-concave surface of and directive lampshade 40 luminous at light emitting diode 21, on the light reflected back circuit board 20 of meeting with the light emitting diode 21 of part, therefore, the luminous efficiency of the utility model light-emitting diode lamp tube is reduced.
In view of this, on circuit board 20, more can paste reflecting element (not illustrating among the figure) in the utility model lamp tube structure of light-emitting diode, or, only for illustrating, do not limit to application category of the present utility model with this at this with electroplating surface one deck reflector layer of plating mode at circuit board 20; And reflecting element can also be fixed in reflecting element on the circuit board 20 by screw-in version, or anyly can reach fixed form, when accommodation space 11 by the return reflection surface cooling base 10 of lampshade 40 of the light of light emitting diode 21, so as to the light that will reflect by the convex-concave surface of lampshade 40 again secondary reflection outwards disperse, reach the effect of the luminous efficiency that increases the utility model light-emitting diode lamp tube.
