Abstract
A light emitting diode (LED) fluorescent lamp comprises a heat radiation base, a lampshade, a light source substrate, a drive circuit and connectors, wherein the lampshade and the light source substrate are fixed on the heat radiation base, the connectors are respectively installed on the end parts of the heat radiation base and the lampshade, the drive circuit is connected to the light source substrate through a conducting wire, the heat radiation base is provided with a fin, and the cross section of the heat radiation base is of a semicircular shape. Due to adopting the LED fluorescent lamp, the heat radiation effect of the LED fluorescent lamp can be effectively improved, and the service life of the LED fluorescent lamp can be prolonged.
Description
Technical field
The utility model relates to the LED lighting field, particularly a kind of LED fluorescent lamp.
Background technology
LED (LightingEmittingDiode) illumination promptly is a led lighting, is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, in semiconductor, through carrier compound energy of emitting surplus takes place and causes photo emissions, directly sends red, yellow, blue, green, blue or green, orange, purple, white light; The LED illuminating product utilizes LED as the produced ligthing paraphernalia of light source exactly.The LED illuminating product has that volume is little, power consumption is low, long service life, advantage such as environmental and durable, be called as the 4th generation lighting source or green light source.
Existing LED fluorescent lamp generally comprises lampshade, LED lamp group, drive circuit and base, and said lampshade is fixedly connected with said base, and said drive circuit and LED lamp group are installed on the said base.In order to ensure the service life of said LED fluorescent lamp, generally need on base, set up heat abstractor.But the heat abstractor of existing LED fluorescent lamp is airtight shape, and heat can't be in time outer diffusing, and drive circuit generally is contained in base inside, makes that existing LED fluorescent lamp heat radiation effect is relatively poor, lifetime.
The utility model content
The problem that the utility model solves provides a kind of LED fluorescent lamp, solves the relatively poor short problem in service life that causes of existing LED fluorescent lamp heat radiation.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of LED fluorescent lamp; Comprise radiating seat, be fixed in lampshade and light source substrate, drive circuit on the radiating seat, be installed in the connector of said radiating seat and lampshade end; Said drive circuit is connected in light source substrate through lead; Said radiating seat is provided with fin, and said radiating seat cross section is semicircle.
Further, said radiating seat both sides are provided with groove.
Further, said lampshade both sides are provided with the lug, nib that is interlockingly connected with said groove.
Further, said lampshade both sides are provided with auxilliary rib.
Further, said connector connects power supply.
Compared with prior art, the advantage of the utility model technical scheme is:
Through fin is set on radiating seat and with its Cross section Design for semicircle, strengthened the inner cross-ventilation of radiating seat and increased the contact area of radiating seat and air, thereby improved the radiating effect of LED fluorescent lamp.
Description of drawings
Fig. 1 is the utility model specific embodiment sketch map.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
Fig. 1 is the utility model specific embodiment sketch map.As shown in Figure 1, a kind of LED fluorescent lamp comprises radiating seat 1, is fixed in lampshade 2 and light source substrate (not shown), drive circuit (not shown) on the said radiating seat, is installed on the connector 3 of said radiating seat 1 and lampshade 2 ends.
Said radiating seat 1 is provided with fin 11, and its cross section is semicircle, and this design has not only increased the contact area of radiating seat 1 with air, and has strengthened the cross-ventilation in the radiating seat 1, thereby improves radiating effect.
Said radiating seat 1 both sides are provided with groove 12, and said groove 12 is the U type, and are complementary with lug, nib 21 on the said lampshade 2, form snapping and connect.
Also be provided with auxilliary rib 22 on the said lampshade 2, can strengthen the fastness of lampshade 2 and radiating seat 1 snapping.
Said drive circuit is connected in light source substrate through lead, and it can be positioned over said connector 3 inner or relative connectors 3 and radiating seat 1 independent the setting, can reduce the generation of LED fluorescent lamp internal heat like this; Said light source substrate then is installed on the plane of radiating seat, can adopt snapping to connect or the screw fixed connection; Said connector 3 is used to connect external power source, supplies power to light source substrate.
The described LED fluorescent lamp of the utility model specific embodiment; Through fin being set on radiating seat and its Cross section Design being semicircle; Strengthen the inner cross-ventilation of radiating seat and increased the contact area of radiating seat and air, thereby improved the radiating effect of LED fluorescent lamp.
Though the utility model with preferred embodiment openly as above; But it is not to be used for limiting the utility model; Any those skilled in the art are in spirit that does not break away from the utility model and scope; Can make possible change and modification, so the protection domain of the utility model should be as the criterion with the scope that the utility model claim is defined.
Claims (5)
