Abstract
The invention discloses an LED panel lamp. The LED panel lamp comprises a frame, an LED light source plate and LED lamp beads, wherein the LED light source plate and the LED lamp beads are arranged in the frame. A back frame is arranged on one side of the frame. The back frame is sequentially provided with a reflection sheet, a light guiding plate and a diffusion plate. The part, corresponding to one side of the reflection sheet, of the light guiding plate is provided with protruding micro beads. Thus, the light guiding plate with the micro beads has the beneficial effects of being high in light transmittance and low in light loss, and meanwhile the light intensity of the whole light emitting face of the LED panel lamp is distributed evenly. The problems that losses of energy of light, refracted by a light guiding plate provided with lattice points in a printing manner, of an existing LED light source are generated, brightness is not even, and the light emitting effect of the panel lamp is reduced are solved.
Description
Technical field
The present invention relates to LED lamp, particularly to a kind of LED panel lamp.
Background technology
LED light source is as a kind of novel solid light source, not only have that power consumption is low, volume is little, fast response time, long working life, be prone to dim the advantages such as toning, energy-conserving and environment-protective, produce at it, manufacture, will significantly surmount the conventional light source such as electric filament lamp, fluorescent lamp in terms of ease for use.LED light source is typically arranged on panel light frame facet by the panel light of existing structure, the light that LED light source sends reflects (bottom surface of light guide plate utilizes UV screen printing technology to stamp site) by light guide plate, light is made to derive from panel light front, the light sent due to LED light source is reflected by light guide plate, a lot of luminous energy can be lost, reduce the illumination effect of panel light.It addition, due also to the self-characteristic of LED light source, the light that LED light source sends focuses mostly at the dead ahead of LED, and the light distribution of whole exiting surface is uneven, center light intensity, and surrounding is the most weak, causes the brightness irregularities of luminescent panel.
Summary of the invention
In view of above-mentioned present situation, the technical problem to be solved in the present invention is to avoid the deficiencies in the prior art, and proposes a kind of light extraction efficiency height, uniform light and LED panel lamp easy to assembly.
The technical solution of the present invention is: a kind of LED panel lamp, including, frame, and is positioned at frame and is provided with LED light source plate and LED lamp bead, is provided with back frame in described frame side；In described back frame, wherein it is sequentially provided with reflector plate, light guide plate and diffuser plate, the microballon that the surface of the light guide plate of corresponding reflector plate side is conformed with.Therefore, by with the light guide plate of microballon not only there is the feature that light transmittance is high, light loss is little, but also have and make the light distribution of the whole exiting surface of LED panel lamp uniform.
In the present invention, involved microballon is semicircle spheroid, or arc body.
Further, involved microballon is glass, or the glass microballoon that PC material is made, or PC microballon.
The invention has the beneficial effects as follows: by the light guide plate with microballon structure as optical design, optical design because of its uniqueness, the light that the LED light source that can make side and come sends directly penetrates from light guide plate front, solving traditional panel light light guide plate uses site refraction and total reflection technology to cause light losing very big, the problem that the light distribution of the whole exiting surface of LED panel lamp is uneven.
Accompanying drawing explanation
Fig. 1 is the topology view of the present invention；
Fig. 2 is Fig. 1 light conducting plate structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described.
See a kind of LED panel lamp shown in Fig. 1 to Fig. 2, this LED panel lamp, including frame 1, and be positioned at frame and be provided with LED light source plate and LED lamp bead 5, it is provided with back frame 6 in described frame 1 side, in the present invention, described back frame 6 is sequentially provided with reflector plate 4, light guide plate 3 and diffuser plate 2, the microballon 7 that the surface of the light guide plate 3 of corresponding reflector plate 4 side is conformed with.The glass microballoon that the present embodiment uses.So, utilize and with the light guide plate of microballon not only there is the feature that light transmittance is high, light loss is little, but also have and make the light distribution of the whole exiting surface of LED panel lamp uniform.In the present invention, involved microballon 7 is semicircle spheroid.
In above-mentioned, involved microballon 7 is in addition to selecting semicircle spheroid, it is also possible to select arc body.
In above-mentioned, involved microballon 7 is in addition to selecting glass microballoon, it is also possible to select the PC microballon that PC material is made.
In above-mentioned, involved microballon 7 is integrated material with light guide plate 3 and makes, or two body structures.During according to two body structures, it is fixed on light guide plate by modes such as bonding or hot melts.
