The appearance that integrates the LED (Light-emitting diode, light emitting diode) of various advantages, the arrival that is declaring publicly new solid light source epoch undoubtedly.LED is a kind of semiconductor that electric energy can be converted into visible light, it changed the incandescent lamp tungsten filament luminous with the luminous principle of energy-saving fluorescent lamp tricolor powder, and adopt electroluminescence, have long, numerous advantages such as light efficiency is high, radiationless and low-power consumption of life-span.The spectrum of LED almost all concentrates on visible light frequency band, light quality height, and essentially no radiation belongs to typical green illumination light source; Life-span surpasses 100,000 hours, and reliability and durability, maintenance cost is very cheap.
But the annular lamp tube of market is also being continued to use fluorescent tube now, contains noxious material " mercury " in the fluorescent tube, and itself can cause environmental pollution, not environmental protection, and also fluorescent tube is broken easily; Fluorescent tube also contains ultraviolet ray and other radiation simultaneously, and noise is big when using, short with respect to LED service life, energy consumption is big, so people thirst for obtaining always a kind of energy-conservation, surface temperature is low, long service life, pollution-free, noiselessness, not breakable annular lamp tube.
[utility model content]
Have contaminated environment, easy broken, many technological deficiencies such as energy consumption is big, service life is short, noise is big at fluorescent tube traditional in the prior art, the purpose of this utility model be to provide a kind of energy-conservation, surface temperature is low, long service life, pollution-free, noiselessness, not breakable annular lamp tube.
In order to reach above-mentioned technical purpose, the technical scheme that the utility model is taked is a kind of LED annular daylight lamp pipe, comprise annular heat-radiating substrate, be arranged on the annular circuit board on the annular heat-radiating substrate, described annular circuit board is gone into battle and is shown plurality of LEDs, and an annular light transmission casing covers plurality of LEDs and is fixed on the heat-radiating substrate.
Because the utility model adopts the LED of energy-conserving and environment-protective as light source, therefore LED annular lamp tube of the present utility model has advantages such as energy-saving and environmental protection are pollution-free, long service life, noiselessness with respect to traditional fluorescent tube, and lamp tube structure is simple, cost of manufacture is cheap.
Preferably, described annular circuit board is fixed on the annular heat-radiating substrate by the heat conduction colloid.
Preferably, described annular light transmission casing is provided with the substrate installation step at bottom end face, be provided with many group screw joint pins in the inwall both sides of annular light transmission casing, the upper surface of described screw joint pin is concordant with the substrate installation step, described screw joint pin axially is provided with screw connecting hole along it, described annular heat-radiating substrate is placed on the substrate installation step, the corresponding screw mounting hole of described annular heat-radiating substrate is provided with the substrate fixing hole, and a plurality of screws pass the substrate fixing hole respectively and are screwed into screw connecting hole annular light transmission casing is fixed on the annular heat-radiating substrate.
Preferably, described annular light transmission casing inwall is provided with one deck light-mixed layer.
Preferably, described annular circuit board is formed by the combination of multistage arc circuit board.
Preferably, described annular circuit board is that 89 ° arc circuit board combination forms by four sections central angles.

[specific embodiment]
In order to set forth design concept of the present invention in further detail, be described in detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, the invention discloses a kind of LED annular lamp tube, comprise annular heat-radiating substrate 1, be arranged on the annular circuit board 2 on the annular heat-radiating substrate 1, described annular circuit board 2 is gone into battle and is shown plurality of LEDs 3, one annular light transmission casings 4 and cover plurality of LEDs 3 and be fixed on the heat-radiating substrate 1; The fixed form of annular circuit board 3 preferably adopts heat conduction colloid 8 to be fixed on the annular heat-radiating substrate 1, can improve the radiating effect of light fixture itself like this in stationary annular circuit board 3; Heat conduction colloid 8 can be selected heat conductive silica gel for use.In order further to save the cost of manufacture of light fixture, the cross section of the utility model LED annular lamp tube is totally enclosed arch, has saved the processing and fabricating cost with respect to traditional circular cross section.Bottom end face at annular light transmission casing 4 is provided with substrate installation step 5, the inwall both sides of annular light transmission casing 4 are provided with many group screw joint pins 7, the upper surface of screw joint pin 6 is concordant with substrate installation step 5, described screw joint pin 6 is provided with screw connecting hole H along its L, described annular heat-radiating substrate 1 is placed on the substrate installation step 5, described annular heat-radiating substrate 1 corresponding screw connecting hole H is provided with substrate fixing hole 9, and a plurality of screws 8 pass substrate fixing hole 9 respectively and are screwed into screw connecting hole H annular light transmission casing 4 is fixed on the annular heat-radiating substrate 1.
For make fluorescent tube to go out light effect softer, one deck light-mixed layer 41 can be set at the inwall of annular light transmission casing 4, light-mixed layer 41 can be the astigmatic film with mixed light effect that is coated in the dope layer on annular light transmission casing 4 inwalls or presets.
Because processing monoblock annular circuit board 2 can be wasted most of raw material, annular circuit board 2 therefore of the present utility model adopts the combination of multistage arc circuit board to form, as shown in Figure 7, the preferred employing by four sections central angle alpha is that 89 ° arc circuit board 21,22,23,24 combines, be electrically connected between each section arc circuit board, finally be connected with external power supply by lead 9; Processing and fabricating arc circuit board 21,22,23,24 can be cut down cost of manufacture significantly with respect to disposable processing monoblock loop circuit version 2 respectively.
Because the utility model adopts the LED of energy-conserving and environment-protective as light source, therefore LED annular lamp tube of the present utility model has advantages such as energy-saving and environmental protection are pollution-free, long service life, noiselessness with respect to traditional fluorescent tube, and annular lamp tube of the present utility model is simple in structure simultaneously, cost of manufacture is cheap.
Or else above only the act break away from the utility model in the creation spirit category of the present utility model conveniently to illustrate, any simple modification that those skilled in the art did of being familiar with this technology still belongs to protection domain of the present utility model with distortion.
