The beneficial effects of the utility model are: owing to adopted said structure, but the utility model direct convenience ground is contained in the place of fluorescent tube electricity-saving lamp installation, as Down lamp, lamp affixed to the ceiling, floor-lamp is on the lightings such as desk lamp, make around the translucent cover and the bottom can both be luminous, shape such as fluorescent tube electricity-saving lamp.Simultaneously, the utility model has very strong practicality and promotional value with the advantage of LED illumination, can be widely used in family, public place etc.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is the installation diagram of first kind of embodiment of the utility model;

Fig. 2 is the installation diagram of second kind of embodiment of the utility model.

The specific embodiment

With reference to Fig. 1, the tubular electricity-saving lamp of described LED comprises lamp body 1, and the shell of lamp body 1 is made by insulating materials, is provided with power module 3 in the lamp body 1, and power module 3 can be with rectification after the appendiron core transformer transformation, the power supply of filtering current constant mode; Also can use after the electronic transformer transformation mode of constant current to power; Also can be directly by modes such as powered by direct current.One end of lamp body 1 is provided with the metallic lamp holder 2 that is electrically connected with power module 3, and the classification of lamp holder is screw socket and bayonet socket normally, but also have special.Specification has E27, E14, E26, E12, B22 etc.The other end of described lamp body 1 is provided with the fluorescent tube 5 that lamp bracket 4 is connected with lamp bracket 4, lamp body 1 and lamp bracket 4 constitute an integral body, and lamp bracket 4 and fluorescent tube 5 also are to constitute one, and they can fix by bonding or modes such as screw or button bit, fluorescent tube 5 can be made and insulating materials+metal material material is made with insulating materials or glass, be transparent or semitransparent, but also can design the outside printing opacity of fluorescent tube, inwardly one side is light tight, its shape can be circular, ellipse, square, polygonal etc.The circuit board 7 that LED bulb 6 is housed then is fixed in the fluorescent tube 5, and light is luminous to the outside by the wall of fluorescent tube 5.Fluorescent tube 5 can be one or more pipe, leave the space and surround circle between the tube and tube when many pipes constitute, surround in the fluorescent tube of circle and form the space, the heat that produces when such benefit makes the LED bulb luminous distributes easily, guarantees the luminous intensity and the life-span of LED bulb.The lower end of LED electricity-saving lamp is that the circuit board 9 that LED bulb 10 is housed is fixed on the inner support 8 in addition, fit with light cover 11 then, insert again after the semicanal shape end of inner support 8 one ends and light cover 11 overlaps and be fixed in tubular electricity-saving lamp of complete LED of formation on the mouth of pipe of fluorescent tube 5.Light cover 11 is insulators of printing opacity, and the light that LED bulb 10 sends distributes by it, so just form to around and whole downwards luminous effect.Fluorescent tube 5 can be made into a whole piece pipe in addition, also can be made into two halves and constitutes by mode such as fastening and bonding.Described circuit board 7 and circuit board 9 are provided with several LED bulbs 6 and LED bulb 10, and LED bulb 6 and LED bulb 10 are electrically connected with power module 3.

Lamp holder 2 should join with the outer lamp socket that is complementary, and when connecing corresponding dc voltage and current, can make several LED bulbs 6 and LED bulb 10 luminous by direct connecting circuit plate 7 of lead and circuit board 9.When meeting the domestic 220V of civil power, the 120V of foreign country, during alternating currents such as 230V, then this moment, lamp body 1 will be loaded onto appendiron core transformer and rectification, filtering, constant current or load onto the constant current electronic transformer and mate corresponding current/voltage resupplies circuit board 7 and circuit board 9 by lead and makes several LED bulbs 6 and LED bulb 10 luminous.And LED bulb 6 and LED bulb 10 can be by one or one or more groups, the power and the luminous intensity of the power of LED bulb and the tubular electricity-saving lamp of quantity decision LED, and what the LED bulb was different is connected, and determines the dc source of needed different voltages.

With reference to Fig. 2, different is that the tubular electricity-saving lamp of described LED does not have the lower surface luminous component, light cover is only made a gag 12, the mouth of pipe of directly filling in fluorescent tube 5 is also fixing, but perforate in the middle of the gag 12, also can even on the fluorescent tube end center LED bulb be set as needs to the lower end illumination, the interior space illumination downwards by the middle perforate of gag 12 again that light surrounds through fluorescent tube 5 at lamp bracket 4.Gag 12 also can be made the U type in addition, can the independent U type and the U type that links to each other, and the mouth of pipe that puts fluorescent tube 5 just becomes independently U type pipe and the U type pipe that links to each other.

If the tubular electricity-saving lamp of LED requires brightness higher in addition, then to get the following measure of adopting: the diameter that increases fluorescent tube 5; Fluorescent tube 5 is made of the two halves pipe, and an one side of something is made by the insulating materials of printing opacity, and another one side of something is made by radiating effect preferred metal material or other material, and 7 of circuit boards are close to heat sink material by its outside heat radiation.

In a word; though the utility model has exemplified above-mentioned preferred embodiment, should illustrate, though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
