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.
Fig. 1 is the decomposing schematic representation of ceiling lamp in the present invention.As shown in Figure 1, ceiling lamp of the present invention comprises multiple frame 101, the substrate 102 be connected with frame 101, arranges LED light source 103 on the substrate 101 and is successively set on diffuser plate 104, light guide plate 105, reflective sheeting 106 and the cover plate 107 on frame 101.Above cover plate 107, be also provided with power supply 132, be electrically connected with LED light source 103.In FIG, schematically show only part LED light source 103.
Fig. 3 is the sectional view of ceiling lamp in the present invention.Composition graphs 1 and Fig. 3, multiple LED light source 103 is electrically connected with the first side of substrate 102 by modes such as welding.On the second side of substrate 102, be provided with protruding connecting portion 110.
Frame 101 is roughly in strip, and its quantity is four, and the formation rectangle that is connected to each other.The side plate 114 that this frame 101 comprises top board 112, base plate 113 and is connected between the two, this three connects makes frame 101 form the structure of a side opening.Its latus inframedium 114 comprises lateral surface 108 for connection substrate 102 and medial surface 109.On lateral surface 108, be provided with dovetail groove 111, this dovetail groove 111 extends to the other end from one end of frame 101.The shape of the protruding connecting portion 110 on substrate 102 is corresponding with the shape of this dovetail groove 111, when protruding connecting portion 110 one end from dovetail groove 111 is inserted, just substrate 102 can be connected on frame 101.This simple syndeton makes operation when assembling easier, and connects reliable, there will not be situation about coming off.Frame 101 and substrate 102 all preferably made of aluminum, both can heat conduction better, is beneficial to heat radiation.
On the medial surface 109 of side plate 101, be provided with multiple radiated rib 115, the cross section of this radiated rib 115 is trapezoidal, which increases area of dissipation.
On the lateral surface 108 of side plate 101, be also provided with diffuser plate locating slot 116.More specifically, from lateral surface 108, the parallel beneath of dovetail groove 111 extends the first location-plate 117, second location-plate 118, wherein the first location-plate 117 is positioned at above the second location-plate 118, forms diffuser plate locating slot 116 between the two.The edge of diffuser plate 104 is inserted in diffuser plate locating slot 116.On diffuser plate 104, be evenly distributed with laser point.
At the upper surface of the first location-plate 117, be provided with substrate holding tank 119 and light guide plate positioning table terrace 120, the shape of this substrate holding tank 119 and the bottom shape of substrate 102 suitable, when substrate 102 is connected to after on frame 101, this substrate holding tank 119 can auxiliary positioning further.Light guide plate 105 is placed on light guide plate positioning table terrace 120, and its side is just to LED light source 103.Reflective sheeting 106 posts at light guide plate 105 upper surface.
When LED light source 103 is luminous, light enters from the side of light guide plate 105, and the laser point on light guide plate 105 reflects light and reflects, and light is penetrated from light guide plate 105 bottom surface.Part from light guide plate 105 end face injection light through reflective sheeting 106 reflect after, penetrate from light guide plate 105 bottom surface.Afterwards, light penetrates to throw light on after diffuser plate 104 spreads.
In order to compress diffuser plate 104, light guide plate 105 and reflective sheeting 106, the edge of cover plate 107 is high, medial recess, forms recessed compressed part 121.This compressed part 121 is pressed on reflective sheeting 106.With reference to Fig. 2, at the adjacent of two frames 101, be provided with the installation fixed block 122 of L shape, this installation fixed block 122 comprises orthogonal two parts, on these two parts, is provided with screw 123.On each frame 101, be provided with corresponding connecting hole 124.On cover plate 107, be also provided with corresponding connecting hole.After screw 125 passes through the connecting hole on cover plate 107, the connecting hole 124 on frame 101 successively, be connected with screw 123, thus two frames 101 are linked together, and cover plate 107 is connected with frame 101, whereby diffuser plate 104, light guide plate 105 and reflective sheeting 106 are pressed between cover plate 107 and frame 101 simultaneously.
Fig. 4 is the structural representation lifting block 126 in the present invention.Composition graphs 2 and Fig. 4, the cross section of this lifting block 126 is T-shaped, the lifting portion 128 comprising rim connecting portion 127 and extend out from the middle part of rim connecting portion 127.In lifting portion 128, be provided with hole for hoist 129.The top board 112 of frame 101, base plate 113 edge, be provided with along the length direction of frame 101, the limiting section 130,131 that extends in opposite directions.Distance between these two limiting sections 130,131 is less than the height of the rim connecting portion 127 of lifting block 126, is greater than the height in lifting portion 128, and this defines the sliding groove structure installed for lifting block 128 on frame 101.The rim connecting portion 127 of lifting block 128 inserts from the end of frame 101, between top board 112 and base plate 113 and by limiting section 130,131 spacing, lifting portion 128 stretches out between two limiting sections 130,131, can lift by lifting block 126 to whole ceiling lamp.
In ceiling lamp of the present invention, frame 101 and substrate 102 are cooperatively interacted by protruding connecting portion 110 and dovetail groove 111 and realize being connected, and installation operation is very easy, saves man-hour, connect reliable, improve heat-conducting effect.The cross section of radiated rib 115 is trapezoidal, which in turns increases area of dissipation.In addition, also for diffuser plate 104, light guide plate 105 are located, and improved the structure of cover plate 107, make the location of element more reliable.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
