A kind of induction type full-plastic tube LED fluorescent lamp

Technical field

The utility model relates to field of lamp illumination, relates in particular to a kind of LED fluorescent lamp.

Background technology

Traditional LED fluorescent lamp is the plastic-aluminum shell at present, and namely aluminium section bar adds plastic jacket.If adopt the current control source of non-isolation, then may have the danger of electric shock; Or adopt the current control source of isolating, but circuit design is more complicated, and cost is high.In addition, most of LED fluorescent tubes adopt manual operations to control it and open switching state, but in place such as underground garage, corridors because nobody passes through for a long time, the illumination of full brightness has caused unnecessary power consumption.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, a kind of induction type full-plastic tube LED fluorescent lamp is provided, effectively prevented the danger of getting an electric shock in the use procedure, and have complete bright and other are than the low-light level switching state, can automatically detect real-time condition, the switching of state of a control, thus reach the purpose of more power saving.

Technical solution of the present utility model: a kind of induction type full-plastic tube LED fluorescent lamp, comprise copperhead, fluorescent tube, upper shield is at the end cap of lamp tube ends, be encapsulated in the aluminium base of fluorescent tube inside, rectification filtering module, led module, the LED current control module, aluminium section bar, it is characterized in that: further comprising the induction control module, Fresnel Lenses, described fluorescent tube is full-plastic tube, described LED current control module and rectification filtering module, led module, the induction control module is connected, described Fresnel Lenses is partially submerged in full-plastic tube, and correspondingly clad is firmly responded to human body sensor in the control module.

Further, described full-plastic tube is double-colored plastic tube, is transparent or milky along the led module light emission direction, is lighttight white or other lighttight colors along led module direction backlight.

Further, described full-plastic tube material is PC or PVC.

Further, described full-plastic tube has one for the little shrinkage pool that embeds Fresnel Lenses.

Further, described end cap is the plastic material of insulation.

Further, described induction control module is PIR induction control module.

Further, described LED current control module is non-isolation LED current control module.

The beneficial effects of the utility model are: described full-plastic tube and end cap are plastic material, by the electrical bodies such as rectification filtering module, LED current control module, wire are coated fully, even use cost still can reach the effect of protection against electric shock with respect to the lower non-isolation LED current control module of isolation LED current control module.In addition, described full-plastic tube has one for the little shrinkage pool that embeds Fresnel Lenses, can embed well Fresnel Lenses, the infrared signal that human body is sent very directly sees through Fresnel Lenses, and pass the signal to the induction control module, and then the switching of control led module duty, the purpose of realization power saving.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described:

Extremely shown in Figure 5 such as Fig. 1, a kind of induction type full-plastic tube LED fluorescent lamp, the power supply of outside is connected to copperhead 9, copperhead 9 has wire 10 to be connected to L and the N pin of rectification filtering module 1, the output high direct voltage V+ of rectification filtering module 1 and V-end are connected respectively to V+ and the V-end of LED current control module 3, the LED+ pin of LED current control module 3 and LED-pin are connected respectively to LED+ pin and the LED-pin of led module 2, after the high direct voltage access LED current control module 3, the step-down constant-current driven chip by the SY5804A in its module or the non-isolation of SY5814A and corresponding peripheral electron element produce a fixed current and power respectively to LED+ pin and the LED-pin of led module 2 from LED+ pin and the LED-pin of this module.If PIR induction control module 4 has a high potential to flow to the IN pin of LED current control module 3 from OUT, then the LED full brightness is luminous, otherwise luminous with the brightness of 15%-90%.The VCC+ of LED current control module 3 and GND pin are connected respectively to VCC+ pin and the GND pin of PIR induction control module 4, and power supply is to PIR induction control module 4.The infrared ray that human body discharges produces the signal of telecommunication by the RE200B human body sensor that Fresnel Lenses 5 focuses in the PIR induction control module 4, after being processed by the BISS000 infrared induction signal processor 1 in the PIR induction control module 4 again, produce high potential to its OUT pin, rectification filtering module 1, PIR induction control module 4, led module 2, LED current control module 3, aluminium base 6, aluminium section bar 11 all are sealed in the lamp outer casing that is comprised of Fresnel Lenses 5, end cap 8 and full-plastic tube 7.Because Fresnel Lenses 5, end cap 8 and full-plastic tube 7 are insulating materials, therefore, even use the LED current control module 3 of non-isolation still not have the danger of electric shock.
