The specific embodiment
Illustrate the utility model below in conjunction with accompanying drawing.
Fig. 1 shows a kind of LED fluorescent tube 100, and it comprises LED lamp plate 101, radiator 103, lampshade 104 and drive unit 106.Radiator 103 and lampshade 104 are connected to each other and have formed the shell of LED fluorescent tube 100.On radiator 103, be symmetrically arranged with LED lamp plate 101, and symmetrically arranged these LED lamp plates 101 are by being close to respectively LGP 102 at two ends.The utility model is arranged on LED lamp plate 101 on the sidewall of radiator 103, LED lamp plate 101 arranges along fluorescent tube direction, LED light source is evenly distributed on LED lamp plate, makes a small amount of light source of LED fluorescent tube 100 use just can meet bright dipping even, and can effectively reduce light fixture cost.Lampshade 104 is the Transparent lamp shades with high transmission rate, and its light transmittance can reach more than 95%, can be PC material.Than diffused lampshade, lampshade 104 can improve the light transmittance of light, reduces light loss, improves the utilization rate of light.Consider the glare problem of light fixture, the light-output that the utility model adopts LGP 102 that LED lamp plate 101 is sent, rather than light is directly worn to enough Transparent lamp shades, fluorescent tube can directly be looked at straight without any dazzle and human eye.Be provided with reflecting layer 105 at the back side of LGP 102, the light that LED lamp plate 101 is sent in reflecting layer 105 reflexes to lampshade 102, improves reflection of light efficiency, further improves light utilization efficiency.Reflecting layer 104 is to be made up of the reflecting paper of high reflectance or other high reflection efficiency materials.Due between the lampshade 104 of LED fluorescent tube 100 and LED lamp plate 101 installation sites without limitation in height, it is larger that radiator 103 can do, light fixture heat radiation is better, therefore, drive unit 106 can directly can be built in fluorescent tube, forms lamp and drives the integrated LED fluorescent tube of one.
As shown in Figure 1, LGP 102 is fixed on radiator 103 by slideway chute mode.Drive unit 106 is arranged in the internal cavity being made up of LGP 102 and radiator 103.
Referring to Fig. 2, radiator 103 comprise the fin 201, the first draw-in groove 202,203 that is positioned at radiator 103 bottom openings and the second draw-in groove 204,205 that distribute along radiator 103 outer surfaces and with the first draw-in groove 202,203, the second draw-in grooves 204,205 back to and the groove 206,207 put.The first draw-in groove 202,203 is symmetricly set on the sidewall of radiator 103, in order to hold LED lamp plate 101.The second draw-in groove 204,205 correspondences are arranged on the outside of the first draw-in groove 202,203, in order to hold LGP 102.When installation, LED lamp plate 101 and LGP 102 are inserted to the installation that can complete LED lamp plate 101 and LGP 102 from the port of fluorescent tube 100 along the first draw-in groove and the second draw-in groove.The first draw-in groove is adjacent with the second draw-in groove and put, and makes optical energy irradiation that LED light source sends to LGP, by LGP, light is derived.Groove 206,207 symmetries are opened in the outside of radiator 103, in order to be fixedly connected with lampshade 104.As shown in Figure 2, the architectural feature that radiator 103 is exclusive, make radiator 103 except thering is conventional heat sinking function, also there is the effect that fixed L ED lamp plate 101, LGP 102 are installed, and lampshade 104 can be connected and fixed, reach the effect of one-object-many-purposes, greatly simplified product structure, also saved light fixture cost.In addition, the utility model is set directly at LED lamp plate 101 on radiator 103, there is no other thermoresistance layers between the two, has accelerated the radiating efficiency of LED lamp plate 101.
As shown in Figure 1, LED lamp plate 101 is arranged in the first draw-in groove 202,203 towards the mode of the termination of LGP 102 with its exiting surface, the light-output that LGP 102 is sent LED lamp plate 101.LED lamp plate 101 and LGP 102 keep the length matching, in order to avoid because LGP length is inadequate, the light that LED lamp plate can not be sent is all derived, cause the wasting of resources or affect uniformity of light.
According to a preferred embodiment, the radially-protruding crossbeam 208,209 of oriented LED fluorescent tube 100 central axis in the bottom opening place of radiator 103.The first draw-in groove 202,203, the second draw-in groove 204,205 and groove 206,207 are all arranged on crossbeam 208,209.Drive unit 106 is fixed on crossbeam 208,209.Because drive unit 106 directly contacts with radiator 103 by crossbeam 208,209, can fast heat be passed, improve the radiating efficiency of light fixture.The utility model concentrates design on crossbeam the first draw-in groove, the second draw-in groove and groove, has saved product space.In the time producing, only beam design need be become have certain thickness member, and all mounting grooves are all opened on crossbeam, other ground at radiator can reduce its thickness as far as possible, thus, save cost of material, simultaneously also provide enough large installing space for being arranged on drive unit in radiator, and due to heat sink thickness attenuation, be also extremely conducive to heat radiation.
Referring to Fig. 3, the opening part of lampshade 104 is provided with the flange 210,211 matching with groove 206,207, and flange 210,211 is fixedly connected with lampshade 104 in the mode of buckle connection or form fit with radiator 103.Flange 210,211 can be that elastic component can be also non-elastic member.In the time that flange is elastic component, flange is become to buckle connecting structure with groove design, when mounted, the groove that lampshade 104 is squeezed into radiator 103 can achieve a fixed connection.In the time that flange is non-elastic member, be designed to the member that matches with groove size, when installation, from one end of fluorescent tube 100, flange is inserted along groove direction.
According to a preferred embodiment, radiator 103 and lampshade 104 are all tubular shells of semicircular in shape.。According to a preferred embodiment, the thickness of LGP 102 is at least greater than the width of LED lamp plate 101, and while making LED lamp plate 101 lateral guide tabula rasa 102, the light that LED lamp plate 101 sends is all irradiated to the side of LGP 102, thereby light is all derived.
According to a preferred embodiment, radiator 103 and lampshade 104 keep the shape of coupling mutually, guarantee the moulded of fluorescent tube 100, are also convenient to the installation of lamp cap cover simultaneously.
According to a preferred embodiment, LGP 102 is distributed with site.This site is evenly distributed on LGP, makes light 100 bright dippings even.
According to a preferred embodiment, LED lamp plate 101 is fixed on radiator 103 by two-sided high viscosity heat-conducting glue, prevent that LED lamp plate 101 from moving freely in the first draw-in groove because being subject to extraneous vibration, and two-sided high viscosity conducting strip can also be accelerated the transmission speed of heat, the heat that LED lamp plate is produced passes to radiator 103 rapidly, and then improves the radiating efficiency of light fixture.
The utility model at least can reach following useful technique effect:
1, lampshade adopts Transparent lamp shade, and Transparent lamp shade light transmittance is more than 95%, reduces light loss, improves Luminaire efficiency, improves the utilization rate of light.
