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 surface some fin of spread configuration, a recess is offered to described heat sink area extension 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 lamp of the present invention, its 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 one surfaces some fin 3 of spread configuration, a recess 21 is offered to the extension of fin 3 region 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.The LED lamp of the present embodiment does not need lamp housing, its directly by lamp substrate 2 and fin 3 outside exposed, LED1 produce heat can be distributed in time by fin 3, significantly improve radiating efficiency.
As shown in Fig. 1,2,4, particularly, described securing member is a mounting elastic sheet 5, and mounting elastic sheet 5 comprises a bar shaped arcuation housing 51, and is bent downwardly the block tongue 52 of extension and two respectively by the card base 53 of housing 51 bottom to downward-extension and for pushing down LED-baseplate 4 by housing 51 top.
As shown in Figure 1, 2, 3, for making mounting elastic sheet 5 be fixedly connected with lamp substrate 2, accordingly, in recess 21, be installed with a boss 22, boss 22 offers one with the first draw-in groove 23 of block tongue 52 clamping of mounting elastic sheet 5; Boss 22 both sides are convexly equipped with baffle plate 24, two baffle plate 24 respectively for blocking the two side of LED-baseplate 4, prevent LED-baseplate 4 to be displaced sideways; Be close to bottom recess 21 boss 22 place offer two respectively with the second draw-in groove 25 of two card bases 53 clamping.
As shown in Fig. 1 ~ Fig. 5, by LED-baseplate 4, the concrete mode be fixed on lamp substrate 2 is mounting elastic sheet 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, the housing 51 of mounting elastic sheet 5 is fitted, after laminating with the top of LED-baseplate 4, the block tongue 52 of mounting elastic sheet 5 is positioned at the side of LED-baseplate 4, two card bases 53 of mounting elastic sheet 5 are positioned at the opposite side of LED-baseplate 4, and two card bases 53, for pushing down LED-baseplate 4, prevent LED-baseplate 4 from moving laterally; Then, block tongue 52 is snapped in the first draw-in groove 23 of boss 22, two card bases 53 are snapped in respectively in two second draw-in grooves 25 in recess 21 simultaneously, now, namely achieve object LED-baseplate 4 be installed to by mounting elastic sheet 5 on lamp substrate 2.Because mounting elastic sheet 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 mounting elastic sheet 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 LED 1 is installed on lamp substrate 2 by securing member, mounting elastic sheet 5 is only a kind of preferred structure of securing member, the screw that securing member can certainly adopt this area conventional.
