The LED fluorescent lamp comprises a lamp tube, an aluminum base board, an LED lamp board, and two lamp heads, and further comprises a heat dissipation board, wherein the each lamp head is respectively arranged on one end of the lamp tube, the aluminum base board and the LED lamp board are arranged inside the lamp tube, the LED lamp board is arranged on the upper surface of the aluminum base board, the lower surface of the aluminum base board is attached tightly to the heat dissipation board and is fixed inside the lamp tube, the LED lamp board is electrically connected with at least one lamp heads, and the lamp tube comprises a glass tube and a poly carbonate (PC) cover covered on the glass tube.
Description
Technical field
The utility model relates to light fixture, relates in particular to a kind of LED fluorescent lamp.
Background technology
Common fluorescent lamp requires high to operating ambient temperature, be not easy startup when temperature is low, and heat is given birth in the argon gas ionization during use in the common fluorescent lamp, thereby makes mercury generation steam and send strong ultraviolet ray, and common fluorescent lamp easily glimmers, and affects user's eyesight.In addition, when the fluorescent tube of common fluorescent lamp when breaking, the luminescent substance that flows out in it pollutes the environment and the mankind is damaged.The LED light fixture has the advantages such as energy conversion efficiency is high, on-off effect speed is fast, the life-span long, radiationless and low in energy consumption and is widely used.But LED is afraid of high temperature most, in case it is bad to dispel the heat, will cause luminous efficiency low, and shorten service life.
Summary of the invention
Therefore, for above-mentioned problem, the utility model proposes that a kind of light is soft, the LED fluorescent lamp of long service life, good heat dissipation effect.
For achieving the above object, the utility model has adopted following technical scheme: a kind of LED fluorescent lamp, comprise fluorescent tube, aluminium base, LED lamp plate and two lamp holders, described two lamp holders are located at respectively lamp tube ends, described aluminium base and LED lamp plate are located in the fluorescent tube, described LED lamp plate is located at the aluminium base upper surface, also comprise heat sink, described aluminium base lower surface is close to heat sink and is fixedly arranged in the fluorescent tube, the LED lamp plate is electrically connected with at least one lamp holder, and described fluorescent tube is made of glass tube and the PC cover that is sheathed on the glass tube.
Further, described aluminium base cross section is arc.
Further, the one side that described heat sink is close to aluminium base is provided with the groove of one or more, and the another side cross section is semicircle.
Further, described LED lamp plate is provided with three row LED lamp pearls.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: can be in time the heat of LED lamp be passed on the heat sink by aluminium base by heat sink is set below aluminium base, in time heat radiation, so that the LED lamp plate is difficult for assembling amount of heat, whole light fixture all is in the thermal source radiation, prolonged the service life of LED, improved its radiating effect, and the PC cover has effect luminous, luminous intensity distribution, so that the light of the utility model product is softer, thereby the utlity model has very big dissemination.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of the utility model embodiment.
The specific embodiment
Now with the specific embodiment the utility model is further specified by reference to the accompanying drawings.
Consult shown in Figure 1, a kind of LED fluorescent lamp of the present utility model, comprise fluorescent tube 1, aluminium base 2, LED lamp plate 3, heat sink 4 and two lamp holders, described two lamp holders are located at respectively fluorescent tube 1 two ends, described aluminium base 2 and LED lamp plate 3 are located in the fluorescent tube, described LED lamp plate is located at the aluminium base upper surface, described aluminium base 2 lower surfaces are close to heat sink 4 and are fixedly arranged in the fluorescent tube 1, LED lamp plate 3 is electrically connected with at least one lamp holder, described fluorescent tube 1 is made of glass tube 11 and the PC cover 12 that is sheathed on the glass tube 11, described aluminium base 2 cross sections are arc, the one side that described heat sink 4 is close to aluminium base 2 is provided with two grooves 41, the another side cross section is semicircle, and described LED lamp plate 3 is provided with three row LED lamp pearls 31.
The utility model can be in time be passed to the heat of LED lamp on the heat sink by aluminium base by heat sink is set below aluminium base, in time heat radiation, so that the LED lamp plate is difficult for assembling amount of heat, whole light fixture all is in the thermal source radiation, prolonged the service life of LED, improved its radiating effect, and the PC cover has effect luminous, luminous intensity distribution, so that the light of the utility model product is softer, thereby the utlity model has very big dissemination.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
Claims (4)
