A kind of LED fluorescent tube
[described technical field]
The utility model relates to a kind of fluorescent tube, refers in particular to a kind of LED fluorescent tube.
[background technology]
Now at home lighting generally adopts tengsten lamp and fluorescence as light source, because that these light sources have is cheap for manufacturing cost, low price and luminosity advantages of higher occupy the main flow of illumination at home always.But, tengsten lamp belongs to heat to illuminator, electric energy is luminous after being heated to tungsten filament more than 2000 ℃, electric energy is converted into heat energy earlier and is converted into luminous energy again, in this process, 5% the electric energy of only having an appointment is converted into luminous energy, and other energy major part slatterns with the form of heat energy, and its energy utilization rate is extremely low; Moreover tungsten filament can consume under the condition of high temperature in volatilization, when the tungsten filament bulb that volatilizees has totally also been died, so relatively shortly have only about 5000 hours its service life.And fluorescent lamp belongs to gas-discharge lamp, charges into mercuryvapour in fluorescent tube, and mercuryvapour under high voltage ionization takes place, and sends the light of specific wavelength, and this light fluorescent material on the exciter lamp inside pipe wall again sends soft white light.Though fluorescent lamp increases than tengsten lamp on energy-conservation, but its most fatal shortcoming is to be filled with mercuryvapour in the fluorescent tube, as everyone knows, mercuryvapour is the poison gas that has that health is had serious harm, when the fluorescent tube mercuryvapour that breaks will be elegant comes out to second environmental pollution.So, in today of energy growing tension, develop the efficient height, more energy-conservation and house lighting environmental protection means a great beyond doubt and is related to the major issue of national economy.
[utility model content]
In view of fluorescent tube of the prior art exists that energy consumption is big, service life is short, fluorescent tube easily fragmentation, contaminated environment, be not easy to many defectives such as packed and transported, content of the present utility model is to provide a kind of energy-saving and environmental protection, long service life, be difficult for fragmentation, be convenient to the LED fluorescent tube of packed and transported.
In order to reach above-mentioned technique effect, technical solution adopted in the utility model is a kind of LED fluorescent tube, the strip light transmission casing that comprises a heat-radiating substrate, is arranged on the LED on the heat-radiating substrate and is nested with outside LED and is complementary with heat-radiating substrate, described light transmission casing two ends are respectively arranged with end cap, the binding post that matches with common daylight lamp holder that pair of parallel arranged respectively on the described end cap, described binding post is electrically connected with LED.
It is light source that the utility model adopts LED, LED lamp energy consumption is 10% of a conventional light source, its service life was up to 100000 hours, and it is broken, pollution-free that LED is that solid state light emitter is difficult for, therefore adopt LED be the fluorescent tube of light source have energy-saving and environmental protection pollution-free, be difficult for fragmentation, long service life, be convenient to plurality of advantages such as packed and transported.
Preferably, described light transmission casing is the strip plastic casing of a simulation traditional fluorescent lamp pipe profile.
Preferably, described light transmission casing inwall is provided with a light-diffusing film that is used to spread light.
Preferably, the described heat-radiating substrate back side is provided with the radiating fin that is used to dispel the heat.
Preferably, described radiating fin is circular-arc distribution along the length direction of heat-radiating substrate.
Preferably, the electronic devices and components of the ccontaining lamp tube ends of difference in the described end cap.
Preferably, described LED is installed on the circuit board, and described circuit board is fixed on the heat-radiating substrate by the heat conduction colloid.
Preferably, described led chip directly is encapsulated on the heat-radiating substrate, is printed with the printed circuit that is electrically connected with binding post on the described heat-radiating substrate.
Preferably, described LED is connected in series, and every LEDs is connected with the by-path turn-on diode.

[specific embodiment]
For further detailed elaboration inventive concept of the present utility model, be described in further detail below in conjunction with accompanying drawing.
First kind of embodiment of the present utility model is referring to accompanying drawing 1, Fig. 3, shown in Figure 4, comprise heat-radiating substrate 1, be arranged on the LED2 on the circuit board 3, and strip light transmission casing 4, described circuit board 3 is fixed on the heat-radiating substrate 1 by the heat conduction colloid, described strip light transmission casing 4 has a pair of draw-in groove 41,42, described heat-radiating substrate 1 is provided with and above-mentioned draw-in groove 41,42 another draw-in grooves 11 that are complementary, 12, described strip case 4 is by draw-in groove 41,42 are fixed on the heat-radiating substrate 1, described light transmission casing 4 two ends are respectively arranged with end cap 51,52, described end cap 51, the binding post 61 that matches with common daylight lamp holder that pair of parallel arranged respectively on 52,62, described binding post 61,62 are electrically connected described end cap 51 with LED2, electronic devices and components that can ccontaining lamp tube ends in 52.
Second kind of embodiment of the present utility model is referring to shown in the accompanying drawing 6, Fig. 6 is the sectional view of fluorescent tube part, different with first kind of embodiment is the set-up mode of LED2, directly be encapsulated on the heat-radiating substrate 1 referring to led chip 7 shown in the accompanying drawing 6, help the heat radiation of led chip 7 like this, led chip 7 directly is encapsulated on the heat-radiating substrate 1, and is electrically connected with binding post 61,62 by the printed circuit that is printed on the heat-radiating substrate 1.
Light transmission casing 4 of the present utility model is strip plastic casings of a simulation traditional fluorescent lamp pipe profile; As shown in Figure 5, more even in order to make fluorescent tube go out light effect, can paste one deck light-diffusing film 44 at the inwall of light transmission casing 4, be used to spread light, it is softer to use light effect; As shown in Figure 2, the back side of heat-radiating substrate 1 is provided with the fin 9 that is used to increase area of dissipation, and described radiating fin 9 is circular-arc distribution along the length direction of heat-radiating substrate 1.
