The specific embodiment

As shown in Figure 1, led lamp of the present invention comprises a lamp body 10 and a fixed mount 20 that articulates with lamp body 10 both sides.

See also Fig. 2 to Fig. 3, described lamp body 10 comprises a rectangular frame 11, be installed on a radiator 14 of framework 11 1 sides, be installed on framework 11 and a housing 19 that is arranged side by side with radiator 14 and a transparent light cover 15 that is installed on framework 11 opposite sides.Described radiator 14, housing 19 and light cover 15 surround a host cavity 110 jointly with framework 11.Described framework 11 is made up of the vertical two pairs of

side plates

12,13 that link to each other of head and the tail.Side plate 12 is long than side plate 13.The front interval of each side plate 12 offers two screws 121,123 in order to mounting and fixing support 20.One is arranged at host cavity 110 middle parts and vertical two sidewalls 12 that are connected with crossbeam 16 that side plate 13 be arranged in parallel, makes this host cavity 110 be divided into first host cavity 111 and second host cavity 112.Radiator 14 forms first host cavities 111 jointly with the rear end and the crossbeam 16 of side plate 12,13.Some light emitting diode module 17 are attached at radiator 14 1 sides and are contained in first host cavity 111.One reflection shield 18 is striden and is located at light emitting diode module 17, is used to reflect the light that light emitting diode module 17 is sent.Housing 19 extends upward and crossbeam 16 common second host cavities 112 that form from

sidewall

12,13 front ends.One drive circuit module 30 is contained in this housing 19, is used for electrically connecting with light-emitting diode module 17.

Please consult Fig. 4 simultaneously, described radiator 14 comprises a rectangular substrate 141 and the some fin 143 that extend vertically upward from these substrate 141 upper surfaces.Fin 143 vertically uniformly-spaced is provided with and laterally offers some ventilation slots (figure is mark) along substrate 141 along substrate 141.Offer some installing holes (figure is mark not) around the substrate 141.Some screws (figure mark) pass the installing hole on the substrate 141 and cooperate with

side plate

12,13 and radiator 14 is fixed on the framework 11.The lower surface of substrate 141 closely contacts with light emitting diode module 17, in order to absorb the heat of light emitting diode module 17.

Each light emitting diode module 17 comprises circuit board 172 and some light emitting diodes 174 that evenly is fixed in circuit board 172 1 sides of a lengthwise rectangle.The another side of these circuit boards 172 fits in the lower surface of the substrate 141 of radiator 14.These light emitting diodes 174 are positioned at along on the same straight line of circuit board 172 length directions extension, thereby its heat is conducted on the radiator 14 equably.

Described reflection shield 18 is the metal lamellar body of a bending, and it comprises the reflector 181 of a lengthwise and two installing plates 183 that form from reflector 181 horizontal relative two lateral bucklings.Fixture such as screw etc. pass two installing plates 183 and cooperate with the substrate 141 of radiator 14 and reflection shield 18 is fixed on the lower surface of substrate 141.Reflector 181 is covered with light emitting diode module 17, and convexes with a reflective hole 185 towards each light emitting diode 174.These reflective holes 185 are used to reflect the light that light emitting diode 174 sends.

Described fixed mount 20 comprises a fixture 21 and two pin-jointing pieces 23 that cooperate with fixture 21.

The metal lamellar body of this fixture 21 for roughly taking the shape of the letter U, it comprises the installation portion 212 of a lengthwise, from outward extending in the same way two connecting portions 214 of installation portion 212 opposite ends and respectively from two secured in parallel portions 216 that connecting portion 214 extends in the same way.Offer the through hole 2122 at two intervals on this installation portion 212, lamp body 10 is fixed to the target location so that screw (figure does not show) passes these through holes 2122.The outermost end of each fixed part 216 offers an installing hole 2162 corresponding with the screw 121 of side plate 12, and a relative end of each fixed part 216 offers a lengthwise groove 2164 along the length direction of fixed part 216.Two screws 60 pass two installing holes 2162 of fixed part 216 and cooperate with the screw 121 of the side plate 12 of lamp body 10 and fixture 21 is articulated on the lamp body 10.

Described each pin-jointing piece 23 is a lengthwise metal lamellar body, and the screw 123 of the side plate 12 of the corresponding lamp body 10 of one end offers an installing hole 232, and the other end offers a lengthwise groove 234 along the length direction of pin-jointing piece 23.Two screws 70 pass installing hole 232 respectively and cooperate with the screw 123 of the side plate 12 of lamp body 10 and an end of pin-jointing piece 23 is articulated on the lamp body 10.Two screws 40 pass the groove 2164 of the groove 234 of pin-jointing piece 23 and fixture 21 respectively and cooperate with nut 50 respectively and the other end of pin-jointing piece 23 is fixed on the outside of fixture 21.So, a fixed part 216 of each pin-jointing piece 23, fixture 21 and side plate 12 form tripod structures jointly and the stability of fixed mount 20 are strengthened.The width of groove 2164 and groove 234 is suitable.Each screw 40 has a head (figure is mark not) and reaches from the vertically extending major axis of head (figure is mark).The diameter of this head is big than the width of the groove 234 of second fixture 23, the diameter of this major axis is little than the width of groove 234, so, the major axis of screw 40 is equipped in the

groove

2164 and 234 of fixture and pin-jointing piece and can slides along the length direction of

groove

2164 and 234.

Please consult Fig. 2 and Fig. 3 once more, when fixture 21 and pin-jointing piece 23 are in original position, the outermost end of the

groove

2164,234 of fixture 21 and pin-jointing piece 23 is overlapping, and screw 40 is positioned at the overlapping of

groove

2164,234, nut 50 screw screw 40 major axis than the outer end.Lamp body 10 rotated around fixture 21 change its irradiating angle, simultaneously, screw 40 slides and makes fixture 21 and pin-jointing piece 23 relative motions along the

groove

2164,234 of fixture 21 and pin-jointing piece 23.Please consult Fig. 4 simultaneously, 70 tighten and make nut 50 to screw inner to the major axis that is fixed on screw 40, itself and screw 40 are closely cooperated and lamp body 10 is positioned on the fixed mount 20 fully.

Understandable, among the present invention, pin-jointing piece 23 and fixture 21 the two one of offer groove 234 or groove 2164 and can realize also that lamp body 10 rotates around fixture 21 and change its irradiating angle, simultaneously, fixture 21 and pin-jointing piece 23 relative motions and make screw 40 slide and make fixture 21 and pin-jointing piece 23 relative motions along the groove 234 of the groove 2164 of fixture 21 or pin-jointing piece 23.

More traditional led lamp, the present invention connects the different parts of lamp body 10 respectively by fixture 21, pin-jointing piece 23, has reduced the moment that 10 pairs of fixtures of lamp body 21 produce.And the fixed part 216 of each pin-jointing piece 23, fixture 21 and side plate 12 form tripod structures jointly and the intensity of fixed mount 20 are strengthened, thereby lamp body 10 can firm being fixed on the fixed mount 20.

Understandable, among the present invention, fixed mount 20 also can be made up of a fixture 21 and a pin-jointing piece 23, and this fixture 21 and pin-jointing piece 23 cooperate also can reduce the moment that 10 pairs of fixtures of lamp body 21 produce.
