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 made up of body and the circuit board and the power supply that are equiped with a plurality of LED mostly; The led circuit plate can be installed in the body through parts such as heat sink section bars, then installs through adhesive or screw between circuit board and the heat sink section bar and power supply places the LED fluorescent tube outside.Not enough below above-mentioned mounting structure exists: 1. power supply places the LED fluorescent tube outside, is connected with the LED fluorescent tube through lamp base, exists power supply to be prone to short circuit, short circuit, exists potential safety hazard and globality poor, is unfavorable for installing and replacing LED fluorescent tube; 2 adopt screw that the led circuit plate is fixed in the mode on the body; Exist installation loaded down with trivial details; The deficiency that wastes time and energy is if adopt adhesive the led circuit plate to be fixed on the aluminium section bar that is installed on the body, if the adhesive usable floor area is too small; It is insufficient to cause circuit board to contact with body easily, the influence heat radiation; If the adhesive usable floor area is excessive, because the adhesive thermal resistance is bigger, therefore also can influence the heat conduction and the heat radiation of fluorescent tube to a certain extent, reduce fluorescent tube service life.
Summary of the invention
The purpose of the utility model is to overcome the prior art deficiency, and a kind of Novel LED lamp tube is provided, and its tool good heat dissipation effect, easy for installation, luminous intensity distribution advantage of uniform is arranged.
The utility model solves its technical problem and realizes through following technical approach:
A kind of Novel LED lamp tube; Comprise body, circuit board, power supply, hollow heat sink that LED organizes are installed; The hollow heat sink is fixed in the upper surface of fluorescent tube, and circuit board then is installed in the body through the hollow heat sink, and power supply is installed in the hollow heat sink; It is characterized in that: three of symmetry systems have interior buckling groove on the surface of hollow heat sink in body; Should in buckling groove be used to clamp the circuit board that LED group is installed, and with three groups of circuit boards to fall trapezoidal closely being installed on the hollow heat sink, the upper surface of hollow heat sink inner space is shaped on the power card tankage; Power supply is installed in the hollow heat sink through the power card tankage, and matches with the circuit board that the LED group is installed.
And the upper surface of described hollow heat sink inner space is shaped on the power card tankage.
And two groups of circuit board cross sections that the LED group is installed that described inner card cage clamps are trapezoidal.
And the outer surface of described hollow heat sink is shaped on radiating ribs at interval.
Advantage of the utility model and beneficial effect are:
1. this LED fluorescent tube clamps the circuit board that the LED group is installed through the hollow heat sink; And be positioned the inner surface of heat sink in body; Upper surface through hollow heat sink inner space is shaped on the power card tankage and clamps power supply; Each parts all adopts and clamps structure, therefore need not to use adhesive or screw to fix, and has easy for installation, time saving and energy saving outstanding advantage; And circuit board is in the heat sink full contact, thereby can effectively improve fluorescent tube heat conduction, radiating effect, prolonging lamp tube service life.
2. three of this LED fluorescent tube groups of circuit boards that LED group is installed cut trapezoidally, satisfy LED assembly light needs, have the advantage that light distribution effect is good and be convenient to install.
3. the outer surface of the hollow heat sink of this LED fluorescent tube is shaped on radiating ribs at interval, further improves the radiating efficiency of heat sink thus, prolonging lamp tube service life.
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.
Description of drawings
Fig. 1 is the sectional view of the utility model LED fluorescent tube;
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Fig. 3 is the B portion enlarged drawing of Fig. 1.
The specific embodiment
Through specific embodiment the utility model is done a nearly step below and detail, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of Novel LED lamp tube comprises body 1, hollow heat sink 2, the circuit board 3 of LED assembly is installed, the upper surface that the hollow heat sink is fixed in body that circuit board is installed in the body through the hollow heat sink, and the installation foot (not shown) is all established at the body two ends.The innovation part of this LED fluorescent tube is: the hollow heat sink adopts aluminium alloy extrusions; Buckling groove 9 on the surface of hollow heat sink in body there being three of systems; This inner card cage is trapezoidal with inner surface and the cross section that three groups of circuit board 3 locator cards that LED group is installed are loaded on heat sink closely; Make luminous intensity distribution more even, circuit board is in hollow heat sink full contact, thereby can effectively improve the heat conduction of LED fluorescent tube, radiating effect.Body is through the made interior card platform 6 in its upper end
Be installed in the made outer buckling groove 7 of hollow heat sink lower surface.The upper surface of LED fluorescent tube through its hollow heat sink inner space is shaped on power card tankage 8 and clamps power supply 4 in the hollow heat sink, matches with the circuit board that the LED group is installed.Each parts all adopts and clamps structure, therefore need not to use adhesive or screw to fix, and has advantage easy for installation, that globality is strong.The outer surface of the hollow heat sink of fluorescent tube is shaped on radiating ribs 5 at interval, further improves the radiating efficiency of heat sink thus.
