Description
Technical field
The utility model is related to lighting field, more particularly to a kind of LED panel lamp.
Background technology
LED panel lamp be it is a kind of obtain in recent years fast development light, its have energy-efficient, environmental protection,
The advantages of light soft uniform, easy for installation, good appearance, in order to obtain homogeneous soft, not dazzling light and subtract as far as possible
The ulking thickness of few LED flat lamp, existing LED panel lamp uses light source side mode mostly, using light guide plate by LED/light source
The luminous point sent is converted into face light.
But when using above-mentioned light source side-arrangement structure, light extraction efficiency will necessarily be on light conduction path by respective degrees
Loss, influence is produced on the brightness of flat lamp, in order to reduce the loss of above-mentioned light extraction efficiency as far as possible, it is necessary to ensure that LED is sent out
Light unit has stable position corresponding relation with light guide plate.Existing LED flat lamp easily occurs in transport, installation process
The position of light guide plate shifts, and causes the light direction of LED unit and the light direction that enters of light guide plate to misplace, and influences to light
The conversion efficiency of line and the using effect of LED panel lamp.In addition, existing structure can not protect LED, transport in panel light,
Light guide plate is easily rocked in installation process, hits LED support, and LED support is the materials such as frangible resin, ceramics, and LED is because of branch
There is mechanical damage in frame destruction；Meanwhile, light guide plate causes flexible easily by environment temperature, effects of humidity change, on business poor, leaded light
The light guide plate extruding LED that the factors such as plate moisture absorption expansion are caused not only results in LED infringements, while the heat that LED lamp bead is produced
Light guide plate can be toasted because being combined closely light guide plate and LED support, make the most important screen print lattice-point ink volatilization of light guide plate and make
Into the phenomenon such as light transmittance decline, shadow, mottled, quality of lighting is remarkably decreased.
A kind of utility model patent " LED ultra-thin panels lamp " of Application No. 201220477513.8, which discloses one kind, to be prevented
The flat lamp that light guide plate is slided, as shown in figure 4, including lamp door 1 and cover plate 2, the inner side of lamp door 1 is provided with LED unit 7, institute
State lamp door 1 and cover plate 2 constitute be stacked with successively from bottom to top in an accommodation space, the accommodation space astigmatism plate 3, light guide plate 4,
