Description

A kind of compact type LED energy-saving lamp

Technical field

The utility model relates to a kind of lighting device, particularly a kind of many LED fluorescent tubes, compact type LED energy-saving lamp of body and driver of comprising.

Background technology

The LED electricity-saving lamp had been rapidly developed in recent years as the environmental protection light source, particularly contained the built-in compact type LED energy-saving lamp of many LED fluorescent tubes, driver in the hall, indoor extensive application.This compact type LED energy-saving lamp, main by the body with screw socket, be contained in many LED fluorescent tubes of body bottom and place the driver of body cavity to form, wherein branched fluorescent tube is distributed on the face of cylinder take the electricity-saving lamp center line as axis, and it is made of the lamp bar that milky body and body include a plurality of LED lamp pearls.This class LED electricity-saving lamp, the backward inboard wall of tube body of its lamp bar does not have the direct illumination of LED lamp pearl, the secondary light-emitting surface brightness is lower, and the side projection area of energy-saving lamp tube light-emitting area is large than the projected area of vertical light-emitting face, the illumination of side direction irradiation area is obviously greater than the illumination in vertical irradiation district, therefore, people usually install and use the LED electricity-saving lamp is horizontal.As in application scenarios such as desk lamp, show windows.Yet, because being connected by the flank that cooperates, the electrical connection between the screw socket of electricity-saving lamp and the lamp socket and structure finish, the heating of screw thread contact-making surface is killed phenomenon and is occured when avoiding work, cooperates loose between the screw socket of lamp holder and the screw of supporting lamp socket.When the lamp holder of electricity-saving lamp was screwed in the screw of lamp socket, whole electricity-saving lamp tended to occur deflection, not only and not in tune between the object of reference, but also can affect lighting effect on every side.

The utility model content

For the existing problem of above-mentioned prior art, the purpose of this utility model is to provide a kind of and supporting lamp socket correct compact type LED energy-saving lamp easy to connect, in place.

The utility model provides a kind of compact type LED energy-saving lamp of following structure, this compact type LED energy-saving lamp, comprise a body, be positioned at body bottom and at least three fluorescent tubes of downward-extension, an intrinsic driver and be positioned at a lamp holder of body upper end, described lamp holder has a guide pillar that joins with the body end face, this guide pillar center line and body center line are collinear, at the symmetric position place of the relative two sides of guide pillar a profile of tooth projection is arranged respectively, when lamp holder cooperates with lamp socket, two profile of tooth projections of on the lamp holder this can be by two corresponding on lamp socket jump ring institute clamps, on the other body end face of guide pillar or the guide pillar end face have a pair of contact pin that is communicated with driver input end that extends along the body centerline direction at least, during use, this a pair of contact pin can insert respectively in two corresponding in the lamp socket jacks and be electrically connected.

After adopting said structure, owing to being provided with the collinear guide pillar of its center line and body center line at the body end face, and the guide pillar of lamp holder matches with corresponding guide hole on the lamp socket, when lamp holder inserts lamp socket, guide pillar center line on the lamp holder can with lamp socket on the guide hole center line collinear or substantially collinear, thereby can reduce electricity-saving lamp with position deflection after lamp socket is connected, with obtain best illuminating effect and with coordinate with reference to phase on every side.Because the symmetric position place of the relative two sides of guide pillar is provided with a pair of profile of tooth projection, when the guide pillar of lamp holder inserts in the guide hole of lamp socket, on the lamp socket with lamp holder on the corresponding Circlip tongs of projection be clipped on the flank of tooth of projection, lamp holder is remained in the lamp socket.To insert on the lamp socket jack direction identical because the guide pillar of lamp holder is inserted into the direction of guide hole on the lamp socket and contact pin on the lamp holder, thereby the convenience that saves time that is connected of electricity-saving lamp and lamp socket.

The specific embodiment

Such as Fig. 1, shown in Figure 2, compact type LED energy-saving lamp comprises a body 7, is positioned at body 7 bottoms to the fluorescent tube 10 of five disjunctors of downward-extension, and an intrinsic driver 9 and a lamp holder 2 that is positioned at body 7 tops consist of.The lamp bar 11 that body 13 that arbitrary fluorescent tube 10 is made by milky PC material and body include a plurality of LED lamp pearls 12 forms, wherein, be placed with lamp bar 11 one sides of LED lamp pearl 12 outwardly, make LED lamp pearl 12 relative body 13 surfaces under the illumination of LED lamp pearl 12, become the secondary light-emitting area, to the radiation luminous energy all around of electricity-saving lamp.

Lamp holder 2 and body 7 disjunctors, this lamp holder 2 has a kidney-shaped guide pillar 4 that joins with body 7 end faces 6, these guide pillar 4 center lines 5 are collinear with body 7 center lines 8, the profile of tooth projection 3 that a triangularity is respectively arranged at the symmetric position place of guide pillar 4 opposite flanks, when lamp holder 2 inserts supporting lamp socket, two profile of tooth projections 3 of on the lamp holder 2 this can by jump ring institute clamp corresponding on the lamp socket, remain on lamp holder in the lamp socket.End face 14 at guide pillar 4 is provided with two pairs along the contact pin 1 of body center line 8 directions extension with the input conducting of driver 9, and during use, these two pairs of contact pins are inserted in the corresponding jack of lamp socket and are electrically connected.

Fig. 3, Fig. 4 show the another kind of embodiment of electricity-saving lamp.In this embodiment, what join with body 7 end faces 6 is a square guide pillar 4, on body 7 end faces 6 of this guide pillar both sides, be provided with symmetrically two pairs along the contact pin 1 of body 7 center lines 8 directions extension with the driver input end conducting, during use, the contact pin correspondence on the lamp holder is inserted in the jack of lamp socket and is electrically connected.

Use a kind of compact type LED energy-saving lamp of the utility model, not only save time with being connected of lamp socket, convenient, and the position deflection that electricity-saving lamp is connected on the lamp socket reduces, can improve and on every side object of reference harmony and illuminating effect.
