Description

A kind of LED fluorescent tube

Technical field

The utility model relates to technical field of lamps, refers in particular to a kind of LED fluorescent tube.

Background technology

At present, the LED fluorescent tube is used more and more widely, wherein, in the heat radiation part of LED fluorescent tube, LED module installed surface generally all is the monoplane, and this installed surface is fixed along the diametric(al) of fluorescent tube, the structure of common LED fluorescent tube as shown in Figure 1 because installed surface makes fluorescent tube inside be separated into the part of upper and lower two equalizations, so, be subject to the structure of this fluorescent tube, the power supply of fluorescent tube is equipped with certain difficulty.In addition, the LED module is to be the Plane Installation mode on installed surface, and with respect to the fluorescent tube transmissive portions branch of arc, differ in each LED position, and the utilization rate of luminous flux of light source is low, and the area of dissipation of fluorescent tube is little, light distribution is not good.

Therefore, based on the defective of above-mentioned existing LED fluorescent tube, need improve existing LED light fixture.

The utility model content

The purpose of this utility model is to provide a kind of LED fluorescent tube at the deficiencies in the prior art, the utilization rate that this LED fluorescent tube has solved the existing luminous flux of light source of existing LED fluorescent tube is low, and the area of dissipation of fluorescent tube is little, light distribution is not good and power supply is installed inconvenient defective.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of LED fluorescent tube, it comprises diffuser, the radiator that fits together, and fluorescent tube inside has first fixed head, second fixed head of fixed L ED module, and first fixed head, second fixed head have angle.

Described first fixed head, second fixed head, one end link to each other, and three end points of first fixed head, second fixed head constitute triangle.

The groove that has fixed L ED module on described first fixed head, second fixed head.

Described first fixed head, second fixed head are structure as a whole.

Described radiator, first fixed head, second fixed head are structure as a whole.

The link of described first fixed head, second fixed head is towards diffuser.

The beneficial effects of the utility model are: fluorescent tube inside has first fixed head, second fixed head of fixed L ED module, the LED module is divided into two groups, respectively be mounted on first fixed head, second fixed head, have bigger space between the fixed head of winning, second fixed head and the radiator thereby make, tube power can be installed easily; Also make the LED module more near diffuser, the light that LED is sent shines on the diffuser more equably; Improved the utilization rate of luminous flux of light source; Improved the efficient of lamp system; Have more energy-saving effect; Increased the area of dissipation of fluorescent tube; The power supply that the bigger built-in fluorescent tube in space is arranged; Optimize the distribution of light intensity.

Fig. 2 is a cross section structure schematic diagram of the present utility model;

Element and Reference numeral:

Diffuser 10, radiator 11,

First fixed head, 12, the second fixed heads 13,

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

See Fig. 2, a kind of LED fluorescent tube of the utility model comprises diffuser 10, the radiator 11 that fits together, diffuser 10 cross section semicirculars in shape, and diffuser 10, radiator 11 are combined into the rounded fluorescent tube in cross section; Different with traditional round lamp tube is that first fixed head 12, second fixed head, 13, the first fixed heads 12, second fixed head 13 that the utility model fluorescent tube inside has fixed L ED module 14 have angle; The groove that has fixed L ED module 14 on described first fixed head 12, second fixed head 13.

Described first fixed head 12, second fixed head, 13 1 ends link to each other, and three end points of first fixed head 12, second fixed head 13 constitute triangle.

The link of described first fixed head 12, second fixed head 13 has bigger space thereby make to win between fixed head 12, second fixed head 13 and the radiator 11 towards diffuser 10, and tube power can be installed easily; In addition, this also makes LED module 14 more near diffuser 10, and the light that LED is sent shines on the diffuser 10 more equably, thereby has reduced to making diffuser 10 brightness even, and the risk that causes losing luminous flux.

The utility model can be that described first fixed head 12, second fixed head 13 are structure as a whole, and can adopt heat sink material to make; Can also be that described radiator 11, first fixed head 12, second fixed head 13 are structure as a whole, all have heat sinking function.

LED fluorescent tube of the present utility model is divided into two groups with LED module 14, respectively is mounted on first fixed head 12, second fixed head 13, makes the spatial distribution of LED and diffuser 10 reach optimum combination, makes illumination more even.

Advantage of the present utility model has: the utilization rate that has improved luminous flux of light source; Improved the efficient of lamp system; Have more energy-saving effect; Increased the area of dissipation of fluorescent tube; The power supply that the bigger built-in fluorescent tube in space is arranged; Optimize the distribution of light intensity.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, and unrestricted the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
