Abstract

The utility model belongs to the technical field of LEDs, and particularly discloses a lamp structure which is simple in structure and better in heat dissipation effect. According to an LED lamp, due to the adoption of the outer shell structure including a base plate, an end cover and an upper cover, various assemblies can be completed at the same time in different working procedures, the assembling process is simplified, the assembling time is shortened, and the assembling efficiency is improved. In addition, due to the arrangements of a heat dissipation plate connected with a light source, a heat dissipation structure on the outer shell and a heat conduction part arranged between the heat dissipation plate and the end cover, the heat dissipation effect is improved, and the service life of the lamp is prolonged.

Description

A kind of LED light fixture

[technical field]

The present invention provides a kind of stable connection, has assembled simple Novel LED lamp by fitting structure and radiator structure are improved.

[summary of the invention]

LED light fixture disclosed by the invention comprises light-passing board, reflector, led light source, heat sink and shell, and shell comprises end cap, base plate and loam cake.Be fixed with drive plate, control panel, electrical connection interface and power supply on the base plate.Base plate is rectangle, and is provided with wall shape projection on the peripheral position on its four limits, has a screwed hole on each projection at least, forms enclosure wall or independent of one another between four wall shape projections.The size of the length of loam cake and wide size and base plate is consistent, the cross section of going up along its length be shaped as a shape, the two ends of width are provided with screwed hole, are used for screwed hole and screw that abutting end covers and realize the fixing of end cap; Offer on two sides on the length direction with base plate on the consistent screwed hole in screwed hole position, by screw or bolt, can realize being connected and fixed between base plate and the loam cake.End cap and on cover and offer radiator structure, can be louvre, also can be the heat radiation crack, or lepidiod fin.

Light-passing board is fixed on by buckle or bonding mode and covers.

The mode of taking buckle to connect, weld, be threaded between heat sink and the led light source realizes fastening, so by screw and be arranged on heat sink led light source on screwed hole or through hole and on cover the corresponding position screwed hole be connected to and cover.

During assembling, at first the parts such as drive plate, control panel, electrical connection interface and power supply are fixed on the base plate with screw thread, then heat sink is connected on the led light source, and then by the screwed hole on screw and/or heat sink and the led light source or through hole heat sink and led light source are fixed to and cover, bonding card and the light-passing board of obtaining, at last loam cake, end cap and base plate are connected and fixed, form whole lamp.

Preferably, screw successively passes screwed hole or the through hole on led light source and the heat sink, then by and on cooperation between the screwed hole that covers, directly be fixed on and cover, omitted the attaching parts between heat sink and the led light source.

Preferably, led light source adopts the method for COB to encapsulate.

Preferably, be provided with heat-conduction component between heat sink and the shell, be embodied in sheet metal or heat-conducting plastic.The setting of heat-conduction component, the heat that led light source is produced transfers out fast by the mode of conducting, and the LED power supply is played a good protection.

Preferably, the top of the portal structures of loam cake is that trapezoidal, trapezoidal top is the luminous zone, and the top that also is portal structures is the triangular shape.

Preferably, light-passing board is armorplate glass.

Alternatively, be provided with between led light source and the loam cake for the radiating subassembly that improves radiating efficiency.

Alternatively, offer on the end cap of both sides for the screwed hole that connects handle, handle is fixed on the end cap by handwheel.

LED light fixture disclosed by the invention owing to adopted the shell mechanism that comprises base plate, end cap and loam cake, can have been simplified assembly technology so that each assembly is finished simultaneously in different operations, shortened installation time, has improved efficiency of assembling.In addition, the heat sink that the present invention connects by light source, the radiator structure on the shell and the setting of the conducting-heat elements between heat sink and the end cap have improved radiating effect, have prolonged the service life of light fixture.

[description of drawings]

Fig. 1 is the explosive view of one embodiment of the invention.

[specific embodiment]

Below in conjunction with preferred embodiment lamp body structure of the present invention is described in detail.

As shown in Figure 1, the cross section of loam cake 3-1 is portal structures, and the top of portal structures is the triangular shape, and the top of triangular shape is used for installing safety glass 4.Be provided with on two sides on the width of loam cake 3-1 and integrated eight floors 5 of loam cake, offer a screwed hole on each floor 5, the screwed hole on the floor 5 is used for connecting end cap 3-1.End cap 3-1 corresponding position upper and floor 5 is provided with screwed hole or through hole, by and the cooperation realization loam cake 3-1 of screw and end cap 3-3 between being connected and fixed.

Be provided with four independently wall shape projections 6 on the base plate 3-2, be connected the corresponding position on the wall shape projection 6 to be provided with for the screwed hole that connects loam cake 3-1 and base plate 3-2 with loam cake 3-1 side plate.
