The utility model content

The utility model has overcome the deficiency that exists in the above-mentioned prior art, and a kind of lighting angle that increases is provided, and enlarges the luminous stem stem of LED of range of exposures.

The technical scheme of the utility model is achieved in that

The luminous stem stem of a kind of LED; Comprise glass stem and two aluminium bases; Two aluminium base right-angled intersections are fixed together, and the led drive circuit that on aluminium base, has been welded leads to lead in glass stem; Lead is with wherein an aluminium base lower end welding is fixing; Every aluminium base each side be fixed with a wiring board, the residing plane of the wiring board of aluminium base sidepiece is vertical with the residing plane of coupled aluminium base, also is fixed with a wiring board on the top of two aluminium bases; The residing plane of the wiring board on two aluminium base tops is all vertical with two residing separately planes of aluminium base, on the wiring board on the wiring board of aluminium base sidepiece and top, all is welded with a plurality of led chips.

As preferably; In the middle of described two aluminium bases; Wherein aluminium base first half central authorities are provided with the breach that vertically is provided with together, and another piece aluminium base Lower Half central authorities correspondence is provided with the breach that vertically is provided with together, two aluminium bases breach through correspondence be inserted in together and welding fixing.

As preferably, be provided with a metal hanger at the two ends up and down of every aluminium base sidepiece, be provided with two gap slots in the correspondence of two ends up and down of the wiring board of aluminium base sidepiece, thereby described metal hanger is inserted in gap slot and crooked wiring board is fixed up.

Adopted the principle of the utility model of technique scheme to be:

The utility model is two aluminium bases to be the right-angled intersection grafting be fixed together, and is fixed with a wiring board then in the both sides of every aluminium base, and also is provided with a wiring board at two aluminium base tops; On above-mentioned wiring board, all be fixed with led chip, make stem stem form the light-emitting block of a rectangular shape, thereby enlarged the field of illumination; The illumination of formation non-blind area; And can improve service life, cut down the consumption of energy, can be used in the various LED light fixtures.

The beneficial effect of the luminous stem stem of the utility model LED is:

1. the utility model is decussation with two aluminium bases and fixes, and the led drive circuit that is welded, and in the corner up and down of aluminium base both sides the metal hook is arranged, and the wiring board gap slot at two ends up and down is inserted in metal hanger, and hook is revolved and turn 90 degrees, just can fastening wiring board.

The aluminium base structure of the utility model have good heat dissipation, be welded conveniently, firm advantage.The temperature of guaranteeing stem stem is below 70 ℃, favourable raising luminous flux, increases service life and reduces light decay.

3.LED tandem compound, and interior dress resistance-capacitance depressurization and rectification circuit use surface mount elements, have the distinguishing feature that cost is low, the operating current variation is little, easy to assembly.

4. the existing equipment of incandescent and technology are accomplished whole lamp and are made, the upgrading and automated production in enormous quantities of favourable incandescent lamp bulb manufacturing enterprise.

The specific embodiment

The specific embodiment of the utility model is following:

Embodiment: the luminous stem stem of a kind of LED; Like Fig. 1, shown in Figure 2, comprise that glass stem 1 and 2, two aluminium base 2 right-angled intersections of two aluminium bases are fixed together; Led drive circuit has been welded on aluminium base 2; In glass stem 1, lead to lead 3, lead 3 is with wherein aluminium base 2 a lower ends welding is fixing, each side is fixed with a wiring board 4 at every aluminium base 2; The wiring board 4 residing planes of aluminium base sidepiece are vertical with coupled aluminium base 2 residing planes; The wiring board 4 residing planes that also are fixed with 4, two aluminium base 2 tops of a wiring board on the top of two aluminium bases 2 are all vertical with two residing separately planes of aluminium base 2, on the wiring board on the wiring board of aluminium base sidepiece and top, all are welded with a plurality of led chips 5.

In the middle of described two aluminium bases 2; Wherein an aluminium base first half central authorities are provided with the breach 6 that vertically is provided with together; Another piece aluminium base Lower Half central authorities correspondence is provided with that 6, two aluminium bases 2 of breach of vertically being provided with together breach through correspondence is inserted in together and welding is fixing.

Be provided with a metal hanger 7 at the two ends up and down of every aluminium base 2 sidepieces, be provided with two gap slots 8, thereby described metal hanger 7 is inserted in the gap slot 8 and crooked wiring board 4 is fixed up in the correspondence of two ends up and down of the wiring board 4 of aluminium base sidepiece.
