Abstract
The utility model provides an LED (Light Emitting Diode) daylight lamp. The LED daylight lamp comprises a lamp frame and a lamp tube; the lamp tube comprises a PC (Poly Carbonate) cover, a radiator and a power supply, wherein the lamp cover and the radiator are provided with semicircular sections which are interworked; and a driving circuit and a light source are both arranged on the radiator, and are sealed though the lamp cover. According to the scheme mentioned above, the driving power source and the light source are in centralized installation on the radiator, so that a compact structure is obtained; moreover, the radiator expands the radiating area by adding the radial ribs, so that the heat produced by the LED light source can be quickly radiated, and as a result, the service life of the lamp tube is greatly prolonged.
Description
Technical field
The utility model relates to technical field of lamps, refers in particular to a kind of LED fluorescent lamp.
Background technology
LED(Lighting Emitting Diode) be light emitting diode, it is a kind of solid-state semiconductor devices, he utilizes semiconductor chip as luminescent material, by carrier compound energy of emitting surplus occuring causes photo emissions in semiconductor, directly send the light of the color such as red, yellow, blue, green, blue or green, orange, purple, white, the LED lamp utilizes LED as the produced lighting of light source exactly.The advantages such as LED has that volume is little, power consumption is low, long service life, photochromic pure, the high and low heat of brightness and environmental protection low-carbon (LC) are the 21 century novel green light sources of generally acknowledging in the world.Traditional LED is mainly used in traffic signal and shows that field, auto industry comprise the range light on brake lamp, taillight, side lamp and the head lamp etc. of the backlight of automotive interior instrument board, acoustics indication lamp, switch, reading lamp and outside, building aviation obstruction beacon, airport etc., nowadays the application outside Indoor environment, in the urban beautification, Landscape Lighting is also more and more extensive, as environment-friendly products, interior decoration also begins to popularize the LED lamp.
But the large-power light-emitting diodes namely chip of LED own can produce very large heat when work, if these heats distribute untimelyly, can have a huge impact its performance and life-span.Shortened the service life of LED lamp, therefore limited to a certain extent the range of application of LED lamp at lighting field, because brightness and the underpower of single led light source, can not just use as illumination, therefore existing LED lamp has generally all been assembled a plurality of led light sources, the number of the led light source of assembling is more, and the brightness of made LED lamp and power also will be higher.And the heat that the intensive use of LED can cause LED to produce is gathered in the less space in a large number and the problem that can not in time distribute, owing to being difficult in time distribute, heat cause the LED temperature to raise, can cause the decay of LED luminescent properties and aging rapidly, greatly reduce service life.
At present, LED fluorescent lamp on the market all is to utilize fluorescent tube tube chamber inner air convection to dispel the heat mostly, and the LED fluorescent lamp electric insulation of this class formation is poor, and radiating effect is also bad.And the driving power of existing fluorescent lamp also all is to be positioned at outside the fluorescent lamp, easily causes because high heat fusing and the danger such as electric leakage.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the LED fluorescent lamp of a kind of simple in structure, good heat dissipation effect, long service life is provided.
For achieving the above object, technical scheme provided by the utility model is: a kind of LED fluorescent lamp, and it is comprised of lamp bracket and fluorescent tube; Fluorescent tube is by PC cover, radiator and electric power generating composition.Wherein, the cross section of lampshade and radiator is semicircle, cooperatively interacts; Drive circuit, light source are installed on the radiator, and seal by lampshade.
The described radiator outside is provided with some radially-arranged muscle to strengthen the effect of heat radiation.
The utility model is after having adopted such scheme, driving power, light source are all installed concentratedly on radiator, and not only compact conformation, and radiator has increased area of dissipation by the muscle that increases radially, the dissipation of heat that can rapidly led light source be sent has prolonged service life of fluorescent tube greatly.
Description of drawings
Fig. 1 is lamp bracket schematic diagram of the present utility model.
Fig. 2 is fluorescent tube schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with institute's drawings attached, preferred embodiment of the present utility model is: referring to accompanying drawing 1 and accompanying drawing 2, the described LED fluorescent lamp of the present embodiment includes lamp bracket 1 and is assemblied in fluorescent tube 2 on the lamp bracket 1, fluorescent tube 2 is made of lampshade 3 and radiator 4, wherein, the cross section of lampshade 3 and radiator 4 is semicircle, and cooperatively interacts; Driving power, be installed on the radiator 4 with the aluminium base of lamp pearl, and by lampshade 3 sealings.Radiator 4 outsides are provided with some radially-arranged muscle 5.After having adopted said structure, drive circuit, lamp pearl are all installed concentratedly on radiator 4, and not only compact conformation, and radiator 4 has increased area of dissipation by the muscle that increases radially, the dissipation of heat that can rapidly led light source be sent has prolonged service life of fluorescent tube greatly.
The embodiment of the above is the preferred embodiment of the utility model only, is not to limit practical range of the present utility model with this, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the present utility model.
