Abstract
The utility model discloses an LED lamp tube, wherein a circuit board is arranged inside the lamp tube, the circuit board is provided with an LED lamp, a lamp tube bracket is provided, the lamp tube is installed on the lamp tube bracket, and a power supply is arranged in the lamp tube bracket. The lamp tube comprises a radiating shell and a lampshade covered on the radiating shell, wherein the radiating shell is a hollow aluminum alloy radiating shell, the circuit board is an aluminum matrix copper-cladding board, and the circuit board is installed on the aluminum alloy radiating shell. The power supply and a light source are separated from each other, and the power supply and the light source are respectively arranged in relatively independent spaces, thereby reducing inner heating energy of the lamp tube.
Description
Technical field
The utility model relates to the LED lighting field, especially a kind of LED fluorescent tube that light emitting source and power supply are separated.
Background technology
In the prior art, comprise two parts in the LED fluorescent tube: light emitting source and power supply, power supply is installed in the light emitting source below, the LED fluorescent tube is in when work, and the LED lamp in the light emitting source is luminous and give out heat, and power supply also can distribute heat during the output electric energy simultaneously, because the heat radiation of the fluorescent tube of sealing is bad, cause a large amount of heat accumulations in fluorescent tube, reduced the life-span of LED lamp and power supply, quickened the aging of fluorescent tube shell; In addition; power supply of the prior art is generally high-voltage constant current source; high-voltage constant current source output HIGH voltage driving LED lamp; output circuit must be taked safeguard measure; son can't not guarantee safety; because the LED lamp is many cascaded structures, when wherein a LEDs lost efficacy, the LED lamp of all series connection all can't be lighted.Restriction based on lamp tube structure, LED lamp of the prior art is generally low power LED lamp, the illumination that realizes higher luminous flux just must be integrated together the LED of enough quantity, imitate under the immovable situation at LED light, the luminous flux of design is high more, needs the LED quantity of employing just many more.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of LED fluorescent tube, helps distributing of power supply and light source heat.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of LED fluorescent tube, be provided with circuit board in the described fluorescent tube, and described circuit board is provided with the LED lamp; Be provided with tube stand, described fluorescent tube is installed on the tube stand, is provided with power supply in the described tube stand; Described fluorescent tube comprises the heat radiation shell, covers on the lampshade on the heat radiation shell; The aluminium alloy heat radiation shell that described heat radiation shell is a hollow, described circuit board is aluminium base copper-clad plate, described circuit board is installed on the aluminium alloy heat radiation shell.Power supply and light emitting source are separated, and place separately in the relatively independent space, reduced the caloric value of fluorescent tube inside.
As improvement, described power supply is a Switching Power Supply.The power supply mode of low-voltage DC voltage-stabilizing, not only safety, and the situation appearance of having avoided load LED to connect too much.
As improvement, described tube stand two ends are provided with lamp socket, and described lamp tube ends is provided with lamp holder, and described lamp holder is installed on the described lamp socket.Fluorescent tube relies on being installed on the tube stand with lamp socket that lamp holder can be fast and convenient.
The beneficial effect that the utility model is compared with prior art brought is:
Light emitting source separates with power supply, and the heat that is distributed separately influence each other little, good heat dissipation effect.
The Switching Power Supply of low-voltage direct is as power supply, safety not only, and avoid the too much situation of load LED string.

Fig. 3 is the holder structure schematic diagram;
Fig. 4 is Switching Power Supply and LED lamp annexation figure.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figures 1 to 3, a kind of LED fluorescent tube, it comprises fluorescent tube 7 and tube stand 6; Described fluorescent tube 7 comprises heat radiation shell 8, covers on the lampshade 9 on the heat radiation shell 8.The aluminium alloy heat radiation shell 8 that described heat radiation shell 8 is a hollow is provided with circuit board 3 in the described fluorescent tube 7, and wherein, present embodiment selects for use aluminium base copper-clad plate as circuit board 3; Select surface mounting high-power LED lamp 4 in the present embodiment for use, described surface mounting high-power LED lamp 4 is installed on the circuit board 3, by solder reflow process, directly weld together surface mounting high-power LED lamp 4 is heat sink with aluminium base copper-clad plate, circuit board 3 is installed on the heat radiation shell 8.Be provided with Switching Power Supply 5 in the described tube stand 6; Above-mentioned tube stand 6 is provided with lamp socket 1, and described fluorescent tube 7 two ends are provided with lamp holder 2, and lamp socket 1 matches with lamp holder 2, and what fluorescent tube 7 dependence lamp holders 2 can be fast and convenient is installed on the tube stand 6 with lamp socket 1.Wherein, the power line access interface 11 of LED lamps in lamp holder 2 on the fluorescent tube 7 the is integrated fluorescent tube 7, lamp socket 1 on the tube stand 6 the is integrated voltage output end mouth 12 of Switching Power Supply 5, make Switching Power Supply 5 transmit electricity to the LED lamp in fluorescent tube 7 by lamp socket 1, lamp holder 2, not only convenient, fast, and safety.
As shown in Figure 4, wherein, because the adding of Switching Power Supply 5, surface mounting high-power LED lamp 4 on fluorescent tube 7 interior circuit boards 3 is divided into some groups, it is one group of LED lamp string 10 that 3～6 surface mounting high-power LED lamps 4 are cascaded, and connect with Switching Power Supply 5 after the parallel connection between every group of LED lamp string 10, this kind connected mode has been avoided taking place because of the unusual situation that has influenced other series LED lamps 4 of indivedual LED lamps 4 again.
As shown in Figure 1, the LED fluorescent tube is when work, surface mounting high-power LED lamp 4 gets electric work and begins heating, in this part heat the overwhelming majority is to derive by aluminium base copper-clad plate, and aluminium base copper-clad plate is directly led on the heat radiation shell 8 that is in contact with it after having absorbed a large amount of heats that surface mounting high-power LED lamp 4 distributed, because heat radiation shell 8 is the aluminium alloy of hollow, its area of dissipation is big, and good heat dissipation effect is distributed to the external world by heat radiation shell 8 from a large amount of heats of aluminium base copper-clad plate.Switching Power Supply 5 also can be distributed the part heat when work, in the heat of this part only was present on the tube stand 6, the space in the tube stand 6 was relatively large, and the heat dissipation problem of power supply also can effectively be solved.
LED fluorescent tube of the present utility model separates light emitting source with power supply, its radiating effect is better, thus the utility model both can install the small-power caloric value little the bigger LED lamp of high-power heat also can be installed.All have this structure and only do to change in form, all belongs to protection category of the present utility model.
