Description
Technical field
The utility model belongs to LED lamp field, particularly a kind of Novel LED lamp tube.
Technical background
Existing LED lamp tube structure is mostly by body and packaged circuit board and an electric power generating composition that is provided with a plurality of LED, the led circuit plate can be installed in the body by parts such as heat radiation configuration materials, then installs by adhesive or screw between circuit board and the heat radiation configuration material and power supply places LED fluorescent tube outside.Above-mentioned mounting structure has the following disadvantages: 1. owing to adopt a packaged circuit board that is provided with a plurality of LED, caused the lighting angle of LED fluorescent tube can't reach 180 °, limited the scope of application; 2. adopt adhesive the led circuit plate to be fixed on the aluminium section bar that is installed on the body, it is insufficient that the adhesive use causes the led circuit plate to contact with body easily, because the adhesive thermal resistance is larger, therefore also can affect to a certain extent heat conduction and the heat radiation of fluorescent tube, reduce fluorescent tube service life; If the mode that adopts screw to install then needs to be increased in the technique of boring, tapping on the body, waste time and energy and install loaded down with trivial details; 3. the supply unit of LED fluorescent tube is placed fluorescent tube outside, is connected with the LED fluorescent tube by lamp base, exist the easily long-term zero load of power supply cause open circuit, the potential safety hazard of easy short circuit when changing, and split installation, the distribution complexity, globality is poor.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency, and a kind of Novel LED lamp tube is provided, and it has, and light distribution angle is large, simple installation and good heat dissipation effect, globality and safe advantage.
The utility model solves its technical problem and realizes by following technical approach:
A kind of Novel LED lamp tube, include two circuit boards that plurality of LEDs is installed, power supply module, the hollow radiating tube, hollow radiating tube body be positioned at the LED fluorescent tube above, two circuit boards that plurality of LEDs is installed then are installed in hollow radiating tube lower surface by two inner card cages, power supply is installed in the hollow radiating tube, it is characterized in that: the hollow radiating tube is shaped with two interior buckling grooves in body lower surface symmetry, should be used for clamping two circuit boards that plurality of LEDs is installed by interior buckling groove, and two groups of circuit boards closely are installed in hollow radiating tube lower surface with the angle that is mutually 165 °, hollow radiating tube inside is shaped with the power supply installing space, power supply places in the power supply installing space in the hollow radiating tube, and matches with two circuit boards that plurality of LEDs is installed.
And described hollow radiating tube inside is shaped with the power supply installing space.
And two groups of circuit board cross sections that plurality of LEDs is installed that described interior buckling groove clamps are " eight " type, are mutually 165 ° of angles.
And the outer surface interval of described hollow radiating tube is shaped with radiating ribs.
Advantage of the present utility model and beneficial effect are:
1. this LED fluorescent tube clamps two circuit boards that plurality of LEDs is installed by the hollow radiating tube, and the lower surface of the body that is positioned to dispel the heat, by the power supply installing space that hollow radiating tube inside is shaped with power supply is installed, circuit board adopts clamping structure, therefore need not to use adhesive or screw to be fixed, have easy for installation, time saving and energy saving outstanding advantages; And, circuit board in radiating tube contact fully, the heat that produces during work directly is diffused in the air by the hollow radiating tube, thereby but Effective Raise fluorescent tube heat conduction, radiating effect, prolonging service life of lamp tube.
2. two of this LED fluorescent tube circuit board cross sections that plurality of LEDs is installed are " eight " type, are mutually 165 ° of angles, satisfy the luminous intensity distribution needs of LED fluorescent tube wide-angle, have the advantage that light distribution angle is large, light distribution effect is good.
3. the spaced radiating ribs of outer surface system of the hollow heat sink of this LED fluorescent tube further improves the radiating efficiency of heat sink, prolonging service life of lamp tube thus.
4. the utility model novelty simple in structure, design science are reasonable, have the advantage of easy for installation, good heat dissipation effect, long service life.
