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.

The specific embodiment

In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.

The invention discloses a kind of LED light fixture; It comprises LED, is used to that the lamp substrate of said LED is installed and on two surfaces of said lamp substrate, arranges the some fin that are provided with; Offer a recess by side of said lamp substrate to lip-deep heat sink area extension of said lamp substrate; Said LED is arranged on said notched bottoms, and the surface that plane, said LED place and said lamp substrate are provided with fin is space crossed shape setting.

LED of the present invention is directly exposed outside with lamp substrate and fin, and the heat that LED produces can in time distribute through fin, has significantly improved radiating efficiency; Simultaneously; The surface that LED of the present invention plane, place and lamp substrate are provided with fin is space crossed shape setting; Be that LED can install with respect to lamp substrate at an angle; The user can regulate the setting angle of LED as required, changes the direction of illumination of LED, thereby has increased the range of exposures of LED.

Below in conjunction with accompanying drawing and specific embodiment the present invention is described in detail.

As depicted in figs. 1 and 2; A kind of LED light fixture that present embodiment provides; Comprise LED 1, be used to that the lamp substrate 2 of LED 1 is installed and on 2 two surfaces of lamp substrate, arrange the some fin 3 that are provided with; Offer a recess 21 by 2 one sides of lamp substrate to lip-deep fin 3 zone extensions of lamp substrate, LED 1 is arranged on recess 21 bottoms, and LED 1 is fixedly arranged on the LED substrate 4; LED substrate 4 and lamp substrate 2 are provided with the surperficial vertical setting of fin 3, and LED substrate 4 is fixedly connected with lamp substrate 2 through a securing member 5.

The LED light fixture of present embodiment does not need lamp housing, and it directly exposes lamp substrate 2 and fin 3 outside, and the heat that LED 1 produces can in time distribute through fin 3, has significantly improved radiating efficiency.Because lamp substrate is provided with fin 3 in two surfaces about in the of 2, has further accelerated the radiating rate of LED 1.

Like Fig. 1,2,5, shown in 6; Said securing member 5 comprises a briquetting 51 and a bar-spring 52; Briquetting 51 comprises a horizontal pressure foot 511 and one and horizontal pressure foot 511 vertically disposed vertical pressing plates 512, spring 52 comprise a horizontally disposed middle part 521 and two respectively by the two ends at middle part 521 to the round pin 522 that extends below and be used to push down LED substrate 4.

Like Fig. 1,2, shown in 3; For securing member 5 is fixed on the lamp substrate 2, accordingly, be installed with a boss 22 in the recess 21; Offer two grooves 23 that are used for 521 two ends, middle part of putting spring 52 on the boss 22; Boss 22 two ends outwards convex with the two side that a baffle plate 24, two baffle plates 24 are used to block LED substrate 4 respectively, prevent that LED substrate 4 is displaced sideways; In the recess 21 next-door neighbour's boss 22 places offer two respectively with the draw-in groove 25 of two round pin 522 clampings; The horizontal pressure foot 511 of briquetting 51 is located at the upper surface of boss 22, 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 through screw.

Like Fig. 1～shown in Figure 5, securing member 5 with the concrete mode that LED substrate 4 is fixed on the lamp substrate 2 is: at first the side of LED substrate 4 and the bottom surface of recess 21 are fitted, make the bottom of LED substrate 4 perpendicular to recess 21; The surface of LED substrate 4 and the sidewall of boss 22 are fitted tightly, and make the baffle plate 24 of boss 22 both sides block the two side of LED substrate 4, prevent that LED substrate 4 is displaced sideways; Next, two of spring 52 is justified pin 522 snap 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; Simultaneously the vertical pressing plate 512 of briquetting 51 is fitted with the sidewall of boss 22; Horizontal pressure foot 511 is fixedly connected with boss 22 through screw, at this moment, has promptly realized through securing member 5 LED substrate 4 being installed to the purpose on the lamp substrate 2.Because securing member 5 adopts snap fit that LED substrate 4 is fixed on the lamp substrate 2, and is quick and easy for installation, is convenient to some special occasions LED 1 directly is installed; When needs are safeguarded light fixture, directly securing member 5 is pulled up from lamp substrate 2, take off LED substrate 4, can repair or replace the LED on the LED substrate 41, safeguard very convenient.
