Description

A kind of LED lamp affixed to the ceiling

[technical field]

The utility model relates to a kind of light fixture, especially refers to a kind of lamp affixed to the ceiling.

[background technology]

LED(Light Emitting Diode) light fixture have the life-span long, light efficiency is high, shock resistance, low energy consumption etc. advantage, belong to green energy-conserving and environment-protective illumination, illumination and decoration field now have been widely used in, and along with encouragement and the popularization of national governments, the LED lamp is more and more popularized and the trend of replacing traditional lighting is gradually arranged.

Lamp affixed to the ceiling is a kind of light fixture that generally uses, and is usually used in bedroom, parlor etc.It much is to have the printed circuit board (PCB) of LED lamp pearl as light source board that traditional LED lamp affixed to the ceiling has, then driving power is installed in the middle of the light source board, the light source board center of such LED lamp affixed to the ceiling just has a very big circumferential notch and passes for driving power so that the space to be provided.Yet such LED lamp affixed to the ceiling is because the center breach is bigger, can make light evenly to distribute and causes and occur shadow zone (be the face shield center because the light that passes through is less, form the darker zone of a slice) on the lamp affixed to the ceiling face shield.

Therefore, in order to overcome above-mentioned defective, be necessary to provide a kind of improved LED lamp affixed to the ceiling.

[utility model content]

The purpose of this utility model is to provide a kind of lampshade center the LED lamp affixed to the ceiling in shadow zone can not occur.

To achieve these goals, the utility model adopts following technical scheme: a kind of LED lamp affixed to the ceiling, comprise shell, driving power, led light source plate and the lampshade of assembling mutually with shell, described LED lamp affixed to the ceiling also comprises support member, described support member makes the certain distance of formation between described led light source plate and the described shell in described enclosure and between described shell and described led light source plate, described driving power is between described shell and described light source board.

Compared to prior art, the utility model LED lamp affixed to the ceiling has following advantage: light is evenly distributed at lampshade, makes the shadow zone can not occur on the lampshade.

[specific embodiment]

Referring to figs. 1 through shown in Figure 5, the utility model LED lamp affixed to the ceiling 100 comprises lampshade 1, led light source plate 3, shell 4, the support member 5 between shell 4 and light source board 3, driving power 6 and terminal box 7.

Shell 4 comprises installed surface 41 and assembling face 42.Assembling face 42 extends from installed surface 41, and has a certain degree with installed surface 41 shapes.Assembling face 42 forms a spatial accommodation 43 around being coated on installed surface 41.Terminal box 7 is installed on the installed surface 41 of shell 4, and a part is arranged in the spatial accommodation 43 of assembling face 42, a part of giving prominence to outside the spatial accommodation 43.The opening of led light source plate 3 is assembled and passed to terminal box 7 and the installed surface 41 of shell 4 mutually.

Support member 5 is hollow structure and links to each other with shell 4 with led light source plate 3 respectively.Support member 5 comprises some independently supports 51, and support 51 is uniformly distributed in the spatial accommodation 43 of shell 4.In the present embodiment, the installed surface 41 of shell 4 is circular, assembling face 42 is the cavity ring around installed surface 41, therefore, support 51 is dispersed to circumference near the position in the center of circle from installed surface 41 and is arranged, make between two two stands 51 a end distance near the center of circle from nearer, near an end distance of circumference away from.Support 51 comprises main part 510 and the autonomous body 510 terminal installation portions 512 that extend round about respectively of U-shaped.Support 51 is fixed on the installed surface 41 of shell 4 by installation portion 512.Light source board 3 passes through the support of support member 5, and forms certain distance between the installed surface 41 of shell 4.Among other embodiment, support 51 can be designed to other shapes as required, as long as can stable support led light source plate 3, as long as the arrangement mode of support 51 also can change as required can stable support led light source plate 3.Driving power 6 is fixed on the installed surface 41 of shell 4.In the present embodiment, the installed surface 41 of one of them support 51 cross-over connection driving powers 6 both sides makes driving power 6 between the installed surface 41 of support 51 and shell 4.Light source board 3 is positioned at a side of support member 5 and the installed surface 41 of shell 4 is positioned at the opposite side of support member 5, and driving power 6 is between the installed surface 41 of support member 5 and shell 4, so light source board 3 and driving power 6 are positioned at differing heights with respect to the installed surface 41 of shell 4.

The center of light source board 3 has an opening 31, and the edge line 310 of opening 31 has some LED lamp pearls 8 that distribute along edge line 310, and the dense degree that lamp pearl 8 is arranged is that the dark space is as the criterion not produce blackspot on lampshade.From lamp pearl 8 direction simultaneously over against led light source plate 3, can't see driving power 6.In the present embodiment, light source board 3 is circular, and diameter is 470mm, and the diameter of opening 31 is 90mm, the 11 LED lamp pearls that distribute around opening 31 edge lines 310 also can change the shape of light source board 3 and opening 31 and the mode that the lamp pearl is arranged as required among other embodiment.

Lampshade 1 comprises assembled portion 10, face shield 12 and assembles portion 10 and the connecting portion 13 of face shield 12.Lampshade 1 is installed on the shell 4 along the assembling direction.Assembled portion 10 matches with the assembling face 42 of shell 4, and assembled portion 10 is assembled in the inside of the assembling face 42 of shell 4.In the present embodiment, lampshade 1 is an arc lampshade that end face is milder, cross section from lampshade 1, face shield 12 is the circular arc of 1434mm for radius, assembled portion 10 is the straight line that forms certain angles with face shield 12, and connecting portion 13 comprises that radius is the arc 130 that is connected with face shield 12 of 30mm and the straight line 132 of connection arc and assembled portion 10.The height of lampshade 1 is 98mm.On the plane perpendicular to cross section, draw concentric circles along the assembling direction, connecting portion 13 can be enclosed fully the circle in inside, radius is greater than the radius of a circle that assembled portion 10 can be enclosed fully in inside.Among other embodiment, lampshade 1 also can be adjusted shape as required.
