Abstract
The invention relates to a light-emitting diode (LED) flat lamp. The LED flat lamp comprises a lampshade, a circuit board and a light guide plate, wherein the circuit board and the light guide plate are arranged in the lampshade. The lampshade is square or round, a control circuit and a lighting power source electrically connected with the control circuit are arranged on the circuit board, the lighting power source is composed of a plurality of surface mounted device (SMD) LEDs, the SMD LEDs are divided into a plurality of groups to be connected in series, and the SMD LEDs in each group are connected in parallel and the number of the SMD LEDs in parallel are the same. Light sources emitted from the SMD LEDs are sent out from side edges of the lampshade from the light guide plate. 3012 small power chips are adopted in the LED flat lamp, and compared with a common 3528 chip, a single 3012 small power chip has a higher lighting effect. The optics principle of the light guide plate is utilized, light is emitted from two sides, and therefore the thickness of the whole LED flat lamp is only 11mm. In addition, light distribution is even, and the lighting effect is high.
Description
Technical field
The present invention relates to a kind of illuminations, especially a kind of LED flat lamp.
Background technology
At present, the room lighting that is widely used mostly is incandescent lamp or fluorescent tube, but the electric light conversion ratio of these two kinds of products is all lower, and caloric value is large, and service life is all shorter.
Led light source has the advantages such as volume is little, energy consumption is low, caloric value is low, the life-span is long as a kind of emerging semiconductor light-emitting elements, some have therefore occurred and has adopted the light fixture of led light source.But these light fixtures are pursued high brightness, adopt high-power LED light source more, and the heat that produces when work is larger, and seriously falling sharply appears at high temperature brightness meeting of LED, has a strong impact on light source life.
Summary of the invention
The technical problem to be solved in the present invention is: the LED that a kind of light is evenly distributed, light efficiency is high flat lamp is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of LED flat lamp, comprise lampshade and be arranged on lampshade interior circuit board and LGP, described lampshade is square or circular, the luminous power that is provided with control circuit on the described circuit board and is electrically connected with control circuit, described luminous power is comprised of a plurality of paster LEDs, shown paster LED is divided into many group series connection, and paster LED is connected in parallel and number in parallel equates in every group; The light source that paster LED sends sends by the side of LGP from lampshade.
Further, the number of paster LED of the present invention is 90～372, and the thickness of described LED flat lamp is 10～11mm.
The invention has the beneficial effects as follows, solved the defective that exists in the background technology, the present invention adopts 3020 small-power chips, compare common 3528 for single and have higher light efficiency, utilize the optical principle of LGP, luminous from both sides, thereby make only 11mm of whole lamp thickness, and light is evenly distributed the light efficiency height.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the preferred embodiments of the present invention.
The specific embodiment
The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of LED flat lamp as shown in Figure 1, comprise lampshade and be arranged on lampshade interior circuit board and LGP, described lampshade is square or circular, the luminous power that is provided with control circuit on the described circuit board and is electrically connected with control circuit, described luminous power is comprised of a plurality of paster LEDs, shown paster LED is divided into many group series connection, and paster LED is connected in parallel and number in parallel equates in every group; The light source that paster LED sends sends by the side of LGP from lampshade.
The number of paster LED shown in Figure 1 is 93, and power is 10 watts.
Just the specific embodiment of the present invention of describing in the above specification, various not illustrating is construed as limiting flesh and blood of the present invention, the person of an ordinary skill in the technical field after having read specification can to before the described specific embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
