Description
Technical field
The utility model relates to a kind of illuminations, is specifically related to a kind of LED fluorescent lamp.
Background technology
LED is light emitting diode, is a kind of emerging lighting engineering, and since light emitting diode is used in a large number, lighting apparatus has just had breakthrough progress.Because the lighting angle of the light source of light emitting diode is close to 180 °, therefore, in the time applying it on LED fluorescent lamp, can cause having much light be not guided to the region of needs illumination and shine into waste.For example, the Chinese utility model patent 201120301360.7 of announcing on July 18th, 2012 has disclosed a kind of LED fluorescent tube.This LED fluorescent tube comprises lamp holder, between this left and right lamp holder, is provided with body, is provided with LED lamp bar in this body, and the two ends of LED lamp bar have circuit to be connected with lamp base, and described body is made up of mount pad and Transparent lamp shade.But, because this LED fluorescent lamp does not arrange light guide structure, although the lower surface of this LED lamp bar is reflective plane, but still cannot solve the problem of light waste.
Utility model content
In view of this, be necessary the LED fluorescent lamp that provides a kind of light source utilization ratio higher.
A kind of LED fluorescent lamp, comprise fluorescent tube, lamp holder, substrate and multiple LED light source, described LED light source is arranged in the middle of this substrate, also comprise radiating piece, this radiating piece comprises supporting part and a pair of supporting walls, this substrate is arranged on this supporting part, described supporting walls is connected to these supporting part both sides and becomes obtuse angle to be obliquely installed with this substrate respectively, on described supporting walls, be respectively equipped with reflecting component, this tube inner wall is provided with two limited blocks, these two limited blocks connect with these two supporting walls respectively, this supporting part and this tube inner wall butt.
Compared with prior art, because two supporting walls of this radiating piece become obtuse angle to be obliquely installed with this substrate, make the light that these LED light sources penetrate be reflexed to the region that needs illumination by this reflecting component, avoided the waste of light, make this LED fluorescent lamp have advantages of that lighting effect is higher.

Detailed description of the invention
Please refer to Fig. 1 and Fig. 2, this LED fluorescent lamp comprises fluorescent tube 10, one radiating piece 20, one substrates 30 and multiple LED light sources 40.This radiating piece 20 is inserted in this fluorescent tube 10.This substrate 30 is a strip structure, and this substrate 30 is fixed on the top of this radiating piece 20 and thermally coupled with this radiating piece 20.These LED light sources 40 are intervally arranged on this substrate 30 along the direction of parallel this substrate 30.
Please refer to Fig. 1 and Fig. 2, this fluorescent tube 10 is round tube shape structure, and its inwall is provided with two limited blocks, and these two limited blocks are two ribs that be arranged in parallel 11,12.
Please refer to Fig. 1 and Fig. 2, this radiating piece 20 comprises supporting part 21, accepting groove 22 and a pair of supporting walls 23,24.This supporting part 21 is block structure, and the bottom of this supporting part 21 is provided with the bearing surface 212 of circular arc.The inwall butt of this bearing surface 212 and this fluorescent tube 10.This accepting groove 22 is arranged on the top of this supporting part 21.These supporting walls 23,24 symmetries are connected to the both sides of the accepting groove 22 of this supporting part 21.On this supporting walls 23,24, post respectively reflecting strips 25,26, the end of this supporting walls 23,24 is provided with stop section 27,28, and two ribs 11,12 of this stop section 27,28 and this fluorescent tube 10 connect.This substrate 30 is inserted in the accepting groove 22 of this radiating piece 20, thermally coupled with this accepting groove 22.This two supporting walls 23,24 is obliquely installed (as shown in Figure 2) with 30 one-tenth obtuse angles of this substrate respectively, the light that the reflecting strips 25,26 on this two support arm 23,24 can be sent towards these fluorescent tube 10 these LED light sources 40 of reflection.
When work, because the bearing surface 212 of the supporting part 21 of this radiating piece 20 is arc, this bearing surface 212 will connect with the inwall of this fluorescent tube 10, and the stop section 27,28 of two supporting walls 23,24 of this radiating piece 20 and two ribs 11,12 of this fluorescent tube 10 connect, therefore limit this radiating piece 20 in the interior rotation of this fluorescent tube 10.This substrate 30 is inserted in the accepting groove 22 of this radiating piece 20, makes this fluorescent tube 10, this radiating piece 20 and this substrate 30 form stable overall structure.
In sum, this bearing surface 212 will connect with the inwall of this fluorescent tube 10, and two supporting walls 23,24 of this radiating piece 20 and two ribs 11,12 of this fluorescent tube 10 connect, thereby has limited this radiating piece 20 in the interior rotation of this fluorescent tube 10.Because 30 one-tenth obtuse angles of two supporting walls 23,24 and this substrate of this radiating piece 20 are obliquely installed, and post reflecting strips 25,26 on these two supporting walls 23,24, make the light that this LED light source 40 penetrates reflex to the region that needs illumination through this reflecting strips 25,26, avoid the waste of light, promoted lighting effect.Have advantages of that light source utilization ratio is higher.
On supporting walls 23,24 described in the utility model, be coated with reflectorised paint to substitute reflecting strips 24,25, also can realize reflecting effect.
