The specific embodiment
The tubular LED lamp of the utility model being convenient to change below in conjunction with the drawings and specific embodiments is described further:
Embodiment one:
To shown in Figure 5, the utility model light fixture comprises two lamp holders 1, lamp body 2 and assembly such as one group of led light source 3 and light source bracket 4 as accompanying drawing 1.Led light source 3 is arranged on the pcb board 32, and pcb board 32 two ends are the power input 32a that is electrically connected with led light source 3, and lamp holder 1 forms with the mutual clamping of the power input 32a of pcb board 32 and is electrically connected.
Shown in accompanying drawing 4,5, lamp holder 1 is pressed two pin cap (or the G5/Fa6 lamp holder) standard design of G13, comprises the cover case 11 that matches with lamp body 2, can be made by the PC plastic material.The bottom of cover case 11 is provided with pin 12 made of copper, and pin 12 other ends interconnect with the copper conductive clip 13 that is arranged in the cover case 11, and conductive clip 13 is clamped the power input 32a of pcb board 32.Conductive clip 13 comprises the substrate 13a that is riveted together mutually with pin 12, and be arranged on two groups of pinch 13b on the substrate 13a, form the draw-in groove of the power input 32a of clamping pcb board 32 between two groups of pinch 13b, when the LED lamp was assembled, pcb board 32 was installed in this draw-in groove.As shown in accompanying drawing 5, two groups of pinch 13b comprise an opposed pinch mutually respectively.Certainly, these two groups of pinches also can be that wherein one group of pinch comprises two pinches, and another group pinch only comprises a pinch, and these three mutual staggered positions of pinch are isosceles triangle and distribute.Wherein substrate 13a and each group pinch 13b integrated punching brake forming.
As shown in Figure 2, lamp body 2 is transparent or semitransparent straight tubes, is provided with strip support 4 in the lamp body 2, and the both sides of pcb board 32 are installed on the support 4.Support 4 is the plastic cement section bar of extrusion molding.As variation scheme of the present utility model, lamp holder 1 can be G5 lamp holder or Fa6 lamp holder or the above-mentioned three kinds of lamp holders (as shown in Figure 6) that increase step; Lamp body 2 can be circular shape, rectangular tube, oval pipe etc.; Led light source 3 can be that pin LED or great power LED are formed.
In addition, can not be subjected to collision deformation, and protection against electric shock etc., be provided with the supporting baffle 11a of the pinch 13b that supports conductive clip 13 at the inner bottom part of the cover case 11 of lamp holder 1 in order to guarantee conductive clip 13.Be provided with and the consistent groove 11b of pinch 13b width with pinch 13b opposite position on the sidewall of supporting baffle 11a.When lamp holder 1 and pcb board 32 clamped mutually, elastic deformation can take place along groove 11b in pinch 13b, so that pcb board successfully snaps in the conductive clip 13.
As shown in Figure 2, led light source 3 is arranged by a plurality of low-power high brightness paster LED 31 dot matrix and is formed.Adopt paster technique to be welded on the bar-shaped LED band of forming on the pcb board 32, pcb board is inserted in the draw-in groove of flame-proof ABS support 4, and support 4 plays the effect of rigid support, guarantees that led light source 3 can be not crooked.As shown in Figure 3, led light source 3 is placed on lamp body 2, and (material is clear glass or perspex, lamp body length is with reference to double-end fluorescent contour length size design) lining, two lamp holder 1 usefulness glue are encapsulated in lamp body 2 two ends, the conductive clip 13 of lamp holder 1 is clamped the power input at pcb board two ends respectively, forms the light fixture of a similar double-end fluorescent.Therefore, substituting with the LED lamp in the process of common fluorescent lamp, can be very easy and quick.
