The objective of the invention is to be achieved through the following technical solutions:
A kind of LED lamp, comprise fluorescent tube and fluorescent-tube fixer, described fluorescent tube comprises lampshade and led chip, fluorescent tube also comprises the fin that is mounted on the led chip bottom, described lampshade and fin all are semi-cylindrical, lampshade and fin are fixedly connected to form cylindrical shell, and led chip is positioned at cylindrical shell inside, and the height of described led chip is no more than half of described cylindrical shell height.
Such scheme is by mounting fin in led chip bottom, and the columned lampshade of tradition is set to semi-cylindrical and is connected with fin, fin fully exposed in air, the raising heat dispersion; In addition, improve luminous angle by the height that reduces led chip, enlarge the light coverage.
As optimal technical scheme, described lampshade is the elasticity lampshade, and the elasticity lampshade is buckled on the fin.
As improvement of the present invention, described fin comprises fin base plate and the some protruding fin of turning up from the fin base plate.
As a further improvement on the present invention, an end of described fluorescent tube is provided with fixed terminal, and the other end is provided with conducting terminal.
For the ease of distinguishing fixed terminal and conducting terminal, prevent that the fluorescent tube dress is anti-, further, described fixed terminal is a crown body, described conducting terminal comprises that two are the pin of claw-like structure.
Described fluorescent-tube fixer comprises roof, ridge body and lamp base, and wherein, roof and ridge body be for detachably fixedlying connected, and ridge body and lamp base are for detachably fixedlying connected.
Concrete, described roof and ridge body are fixed by the steady pin interlocking, and described ridge body and lamp base connect and fix.
The present invention has the following advantages and beneficial effect compared to existing technology:
(1) the present invention is by mounting fin in led chip bottom, and the columned lampshade of tradition is set to semi-cylindrical and is connected with fin, fin fully exposed in air, the raising heat dispersion;
(2) the present invention improves luminous angle by the height that reduces led chip, enlarges the light coverage.
(3) half-terete lampshade and half-terete fin are fixedly connected to form cylindrical shell among the present invention, have improved the attractive in appearance of LED lamp.
(4) fin structure of fin of the present invention designs, and has further improved the heat dispersion of LED lamp.
(5) the present invention is arranged on an end of fluorescent tube with conducting terminal, and the fluorescent tube other end is fixed terminal, avoids the two ends of fluorescent tube are all arranged conducting terminal, and personnel's both hands when mounted contact the conducting terminal of lamp tube ends respectively and the risk of getting an electric shock.
(6) the present invention structurally carries out the differentiation design with fixed terminal and conducting terminal, can prevent that the fluorescent tube dress from can't light on the contrary.
(7) the ridge body of fluorescent-tube fixer of the present invention is detachably fixedlyed connected respectively with roof, lamp base, when any or two needs in the formation part of these three fluorescent-tube fixers are changed, all dismounting and change can be carried out independently, the cost waste of avoiding integral replacing to cause.

The specific embodiment
The present invention is described in further detail below in conjunction with embodiment and accompanying drawing, but the embodiment of the invention is not limited thereto.
As shown in Figure 1, the LED lamp of present embodiment comprises fluorescent tube 2 and fluorescent-tube fixer 1, and fluorescent tube 2 comprises lampshade 21 and led chip 22, and fluorescent tube 2 also comprises the fin 23 that is mounted on led chip 22 bottoms.Fin 23 is formed by the fin base plate and from the some protruding fin that the fin base plate is turned up, the fin base plate fully contacts to absorb the heat that led chip 22 work produce with led chip 22, and protruding fin is distributed to the heat of fin base plate transmission in the air.Lampshade 21 all is semi-cylindrical with fin 23, and lampshade 21 is made by elastic apparent material, and lampshade 21 is buckled on the fin 23, and utilizes binding agent to fix.In order to improve aesthetic property, the semi-cylindrical in configuration design of fin 23 and the structure of lampshade 21 can be complementary, and by fixedly being formed on, the two is the cylindrical shell of one on the visual effect, led chip 22 is positioned at cylindrical shell inside, when the LED lamp is worked, the lampshade 21 that the light that lamp pearl on the led chip on 22 sends is made by transparent material passes, and realizes illumination.
In order to improve the angle of LED lamp wiring irradiation, the height of led chip is set to 40% of cylindrical shell height in the present embodiment.After tested, the LED lamp is the LED lamp of cylindrical shell mid-height than the led chip height in the present embodiment, and the angle that light covers improves 5 degree at least.
As Fig. 2, Fig. 3, shown in Figure 4, one end of fluorescent tube 2 is provided with fixed terminal 24, and the other end is provided with conducting terminal 25, and fixed terminal 24 comprises a crown body 241, conducting terminal 25 comprises that two are the pin 251 of claw-like structure, and pin 251 is the both positive and negative polarity of corresponding power respectively.When being installed in fluorescent tube on the lamp base, because fixed terminal 24 is a crown body 241, and conducting terminal 25 is the pin 251 of two claw-like structures, and conducting terminal 25 structurally is different from fixed terminal 24 fully, so can avoid fluorescent tube to adorn anti-risk; In addition, the claw-like structure of the crown structure of crown body 241 and pin 251 has improved fluorescent tube and lamp base in axial stationarity.
As shown in Figure 5, fluorescent-tube fixer 1 comprises roof 12, ridge body 13 and lamp base 11, and wherein, roof 12 is fixed by the steady pin interlocking with ridge body 13, and ridge body 13 connects and fixes with lamp base 11.
The above embodiment has only expressed embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to type claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the premise of not departing from the present invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
