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 surface of said lamp substrate, arranges the some fin that are provided with; Offer a recess by side of said lamp substrate to said heat sink area extension; 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 light fixture of the present invention, it 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 one 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 fin 3 zone extensions, 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.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 LED1 produces can in time distribute through fin 3, has significantly improved radiating efficiency.

Like Fig. 1,2, shown in 4; Particularly; Said securing member is one shell fragment 5 to be installed, install block tongue 52 that shell fragment 5 comprises that a bar shaped arcuation housing 51, is extended by housing 51 top downwarpings and two respectively by housing 51 bottoms to the card base 53 that extends below and be used to push down LED substrate 4.

Like Fig. 1,2, shown in 3, shell fragment 5 is installed is fixedly connected for making with lamp substrate 2, accordingly, be installed with a boss 22 in the recess 21, offer one and first draw-in groove 23 of block tongue 52 clampings of installation shell fragment 5 on the boss 22; Boss 22 both sides 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; Recess 21 bottoms next-door neighbours boss 22 places offer two respectively with second draw-in groove 25 of two card base 53 clampings.

Like Fig. 1～shown in Figure 5, shell fragment 5 is installed is: at first, make the bottom of LED substrate 4 perpendicular to recess 21 with the bottom surface applying of side with the recess 21 of LED substrate 4 with the concrete mode that LED substrate 4 is fixed on the lamp substrate 2; 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, fitted in the housing that shell fragment 5 is installed 51 and the top of LED substrate 4, after the applying; The block tongue 52 that shell fragment 5 is installed is positioned at a side of LED substrate 4; Two card bases 53 that shell fragment 5 is installed are positioned at the opposite side of LED substrate 4, and two card bases 53 are used to push down LED substrate 4, prevent that LED substrate 4 from moving laterally; Then, block tongue 52 is snapped in first draw-in groove 23 of boss 22, simultaneously two card bases 53 are snapped in respectively in two second draw-in grooves 25 in the recess 21, at this moment, promptly realized LED substrate 4 being installed to the purpose on the lamp substrate 2 through shell fragment 5 is installed.Because being installed, shell fragment 5 adopt snap fit that LED substrate 4 is fixed on the lamp substrate 2, quick and easy for installation, and be convenient to some special occasions LED 1 directly is installed; When needs are safeguarded light fixture, shell fragment 5 directly will be installed pull up from lamp substrate 2, take off LED substrate 4, can repair or replace the LED on the LED substrate 41, safeguard very convenient.
