Abstract

The invention is suitable for the field of lamps and provides an LED (Light-Emitting Diode) lamp. The LED lamp comprises an LED, a lamp substrate which is used for mounting the LED and a plurality of heat radiating sheets which are arrayed on two surfaces of the lamp substrate, wherein one lateral side of the lamp substrate extends towards a heat radiating sheet region on one surface of the lamp substrate and is provided with a notch on an extension part; the LED is arranged at the bottom part of the notch; and a plane where the LED exists and the surfaces, which are provided with the heat radiating sheets, of the lamp substrate are spatially arranged crossly. According to the LED lamp disclosed by the invention, the lamp substrate and the heat radiating fins are directly exposed, so that heat energy generated by the LED can be diffused through the heat radiating fins in time and heat radiation efficiency is improved remarkably. Meanwhile, as the plane where the LED exists and the surfaces, which are provided with the heat radiating sheets, of the lamp substrate are spatially arranged crossly, that is to say, the LED can be mounted at a certain angle relative to the lamp substrate, a user can adjust the mounting angle of the LED according to a need to change the irradiation direction of the LED, and thereby the irradiation scope of the LED is enlarged.

Detailed description of the invention

In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.

The invention discloses a kind of LED lamp, it comprise LED, for install described LED lamp substrate and on described lamp substrate two surfaces some fin of spread configuration, a recess is offered to the heat sink area extension on described lamp substrate surface by described lamp substrate side, described LED is arranged on described notched bottoms, and the surface that described LED place plane and described lamp substrate arrange fin is that space crossed shape is arranged.

LED of the present invention directly by lamp substrate and fin outside exposed, LED produce heat can be distributed in time by fin, significantly improve radiating efficiency; Simultaneously, the surface that LED place plane of the present invention and lamp substrate arrange fin is that space crossed shape is arranged, namely LED can install at an angle relative to lamp substrate, user can regulate the setting angle of LED as required, change the direction of illumination of LED, thus increase the range of exposures of LED.

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

As depicted in figs. 1 and 2, a kind of LED lamp that the present embodiment provides, comprise LED 1, for install LED 1 lamp substrate 2 and on lamp substrate 2 two surfaces some fin 3 of spread configuration, a recess 21 is offered to the fin 3 region extension on lamp substrate surface by lamp substrate 2 one sides, LED 1 is arranged on bottom recess 21, LED 1 is fixedly arranged in a LED-baseplate 4, LED-baseplate 4 and lamp substrate 2 arrange that the surface of fin 3 is vertical to be arranged, and LED-baseplate 4 is fixedly connected with lamp substrate 2 by a securing member 5.

The LED lamp of the present embodiment does not need lamp housing, its directly by lamp substrate 2 and fin 3 outside exposed, LED 1 produce heat can be distributed in time by fin 3, significantly improve radiating efficiency.Because lamp substrate about 2 two surfaces are provided with fin 3, accelerate the radiating rate of LED 1 further.

As shown in Fig. 1,2,5,6, described securing member 5 comprises briquetting 51 and a bar-spring 52, briquetting 51 comprises a horizontal pressure foot 511 and one and the vertically disposed vertical pressing plate 512 of horizontal pressure foot 511, and spring 52 comprises a horizontally disposed middle part 521 and two respectively by the round pin 522 of two ends to downward-extension and for pushing down LED-baseplate 4 at middle part 521.

As shown in Figure 1, 2, 3, be fixed on lamp substrate 2 for making securing member 5, accordingly, a boss 22 is installed with in recess 21, boss 22 offers two grooves 23 for the two ends, middle part 521 of putting spring 52, boss 22 two ends, respectively to being convexly equipped with baffle plate 24, two baffle plate 24 outward for blocking the two side of LED-baseplate 4, prevent LED-baseplate 4 to be displaced sideways; In recess 21, next-door neighbour boss 22 place offers the draw-in groove 25 of two round pin 522 clampings with two respectively; The upper surface of boss 22 is located at by the horizontal pressure foot 511 of briquetting 51, and the vertical pressing plate 512 of briquetting 51 is fitted with the sidewall of boss 22, and horizontal pressure foot 511 is fixedly connected with boss 22 by screw.

As shown in Fig. 1 ~ Fig. 5, by LED-baseplate 4, the concrete mode be fixed on lamp substrate 2 is securing member 5: first fitted the bottom surface of the side of LED-baseplate 4 and recess 21, make LED-baseplate 4 perpendicular to the bottom of recess 21; Then make the sidewall of the surface of LED-baseplate 4 and boss 22 fit tightly, and make the baffle plate 24 of boss 22 both sides block the two side of LED-baseplate 4, prevent LED-baseplate 4 to be displaced sideways; Next, two of spring 52 circle pin 522 are snapped in the draw-in groove 25 of recess 21, and the middle part 521 of spring 52 is located in the groove 23 of boss 22; Next, the horizontal pressure foot 511 of briquetting 51 is fitted with the upper surface of boss 22, the vertical pressing plate 512 of briquetting 51 is fitted with the sidewall of boss 22 simultaneously, horizontal pressure foot 511 is fixedly connected with boss 22 by screw, now, object LED-baseplate 4 be installed to by securing member 5 on lamp substrate 2 is namely achieved.Because securing member 5 adopts snap fit to be fixed on lamp substrate 2 by LED-baseplate 4, quick and easy for installation, be convenient to some special occasions and LED 1 is directly installed; When needs are safeguarded light fixture, directly securing member 5 is pulled up from lamp substrate 2, take off LED-baseplate 4, can the LED 1 in LED-baseplate 4 be repaired or replaced, safeguard very convenient.

The connectors such as should be appreciated that above-mentioned LED 1 is installed on lamp substrate 2 by briquetting 51 and spring 52, briquetting 51 and spring 52 are only a kind of preferred structures of securing member 5, the screw that securing member 5 can certainly adopt this area conventional.
