Description

Multifunctional LED fluorescent lamp

Technical field

The utility model relates to a kind of LED daylight lamp, particularly a kind of be applicable to install in city advertisement lamp box LED daylight lamp.

Background technology

In prior art, for the lighting device in the advertising lamp box of roadside, curbside, city, the LED daylight lamp using energy-conserving and environment-protective, these fluorescent lamps fluorescent tube used has glass lamp, also useful transparent PC pipe after atomization process more.

But in the advertising lamp box of roadside, curbside, use above-mentioned LED daylight lamp to have the following disadvantages:

1) usual, LED lamp bar in the LED fluorescent lamp tube used in described advertising lamp box is one side luminescence, because the beam angle of its luminescence is less, in order to enable illumination just to advertisement panel, so, also to adjust the light angle of installed LED daylight lamp after installing, waste time and energy.Meanwhile, in order to reach uniform illumination, fluorescent tube quantity used also can increase, and causes cost excessive.

2) use some to LED daylight lamp in some advertising lamp box, often pair of LED daylight lamp adopts mode back-to-back to install, but due to the illumination range of one side luminescence limited, therefore, still can there is illumination filaments of sun district in advertisement panel, cause advertising lighting effect poor.

3) the IP degree of protection due to LED daylight lamp fluorescent tube of the prior art is lower, usually IP30 can only be reached, therefore, it is in the environment that humidity, rainwater or steam are larger, very likely make the circuit corrosion in fluorescent tube or short circuit, cause circuit board damage wherein, when fluorescent tube used is glass tube, the personal safety of its explosion hazard passerby may also be made.

Summary of the invention

The technical problems to be solved in the utility model is to provide the Multifunctional LED fluorescent lamp that a kind of beam angle is large, water proof and dust proof is explosion-proof again.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

Multifunctional LED fluorescent lamp of the present utility model, the LED lamp bar comprising fluorescent tube, be placed in the cooling stand in fluorescent tube and be arranged on this cooling stand, every LED lamp pearl of described LED lamp bar is packaged with the spreadlight lens that this LED lamp bead beam angle can be made at 160-170 degree, this spreadlight lens center and LED lamp bead light source center are positioned on same axis, and the two ends of described cooling stand are fixed on the plug at these fluorescent-lamp tube two ends by tapping screw.

Described cooling stand is two surface and the Aluminum Hollow section bar support of rectangular in cross-section, the end face and bottom surface of this cooling stand are equipped with the LED lamp bar described at least one, on the end face that this LED lamp bar is fixed on described cooling stand by bond plies or bottom surface.

The LED drive circuit plate of this fluorescent lamp, after heat-shrinkable T bush encapsulation, is arranged in the hollow cavity of described cooling stand.

The first waterproof grommet is provided with between lighting tube plug and fluorescent tube port; The second waterproof grommet is provided with between the ailhead and plug body of described tapping screw.

Outward flange in the middle part of this fluorescent lamp electrode contact pin is arranged with the 3rd waterproof grommet.

Compared with prior art, on the lamp pearl of the utility model in LED lamp bar, packaging beam angle is at the spreadlight lens of 160-170 degree, make LED daylight lamp lighting angle of the present utility model large, in same advertising lamp box, when under the fluorescent tube quantity used and prior art fluorescent tube quantity used same case, it is better than using the LED daylight lamp of prior art to adopt the advertising lighting effect of the advertising lamp box of the utility model LED daylight lamp.In addition, the utility model adopts the LED lamp bar of double-side in a fluorescent tube, makes described advertising lighting effect better, also greatly can reduce the cost of advertising lamp box lighting device simultaneously.The utility model adopts transparent PC fluorescent tube and arranges water proof and dust proof sealing ring in lighting tube plug, electrode contact pin and head of screw end, makes its IP degree of protection reach the level of IP65.Therefore, in wet environment, use LED daylight lamp of the present utility model, still can guarantee that it has longer service life, be especially suitable for using in refrigerator-freezer freezer.
