Abstract

An LED lamp comprises a lamp holder (1), an LED light bar (2), and an arc lampshade (3) or an elliptical lampshade (5). The LED light bar (2) is disposed inside the lamp holder (1). The arc lampshade (3) or the elliptical lampshade (5) is inserted at the bottom of the lamp holder (1) and covers the LED light bar (2). The right and left sides of the LED light bar (2) are each provided with a reflection plate (109), and the two reflection plates (109) are arranged in an inverted V shape. The LED lamp has a beneficial effect of expanding a light emitting area. Moreover, after being refracted by the lampshade, LED light rays are uniform and soft, thereby effectively solving the dazzling problem of LED light rays, so that LED light rays can better be used for lighting. The reflection plate can further reflect a part of rays that cannot directly spread out of the lampshade, which increases the luminance of the lamp. The reflection plate is covered by the arc lampshade or the elliptical lampshade, which effectively prevents the reflection effect from being affected by dust collected on the reflection plate.

Description

LED luminaires

The present invention relates to apparatus in the field of lighting technology, and more particularly to an LED lamp. Background technique

In the workbench, assembly line, large supermarkets, etc., in order to ensure the normal operation of the work, lighting fixtures are needed. Currently, these places usually use ordinary fluorescent lamps. But ordinary fluorescent lamps have some drawbacks. First, the energy consumption is large, the energy consumption of ordinary fluorescent lamps is equivalent to four times that of LED lamps; Second, fragile, because ordinary fluorescent lamps use glass lamps, glass tubes are easily broken after being impacted; Because ordinary fluorescent lamps contain mercury, it will cause pollution; Fourth, dangerous, ordinary fluorescent lamps use 220V AC, such high voltage can cause harm to the human body; Fifth, short life, ultra-low life is frequent maintenance of lamps .

At present, there are some products that use LED illuminants as the illuminating source. However, most of these products are LED panel lamps or LED fluorescent lamps, and the illumination range is not large enough. At the same time, the LED lamps do not have sufficient heat dissipation, and the original lamp holders need to be matched and the lines are changed. Summary of the invention

It is an object of the present invention to provide an LED luminaire having a wide illumination range.

According to an aspect of the invention, an LED lamp is provided, comprising a lamp holder and an LED light bar, wherein the LED light bar is disposed in the lamp holder, and further comprises a circular arc lamp cover or an elliptical lamp cover, a circular arc lamp cover or an ellipse The lampshade is embedded at the bottom of the lamp holder and covers the LED light bar. The left and right sides of the LED light bar are respectively provided with a reflecting plate, and the two reflecting plates are in a figure-eight shape. Since the LED lamp of the present invention replaces the traditional LED flat lamp cover with a circular arc lamp cover or an elliptical lamp cover, it has the beneficial effect of expanding the illumination range. At the same time, after the LED light is refracted by the lamp cover, the light is hooked and soft, and the solution is effectively solved. The problem of glare of LED light is better applied to lighting operations. At the same time, the reflector can also reflect some of the light that cannot be directly diffused from the lampshade and then spread out from the lampshade to increase the brightness of the lamp.

In addition, the reflector plate of the structure is covered by the arc-shaped lampshade or the elliptical lampshade, which can effectively prevent the reflector from being ashed and affecting the reflection effect.

The utility model has the advantages that it is convenient to install and disassemble the arc-shaped lampshade or the elliptical lampshade, and has Better stability.

In some embodiments, the card holders are provided with card slots for facilitating the installation of the lamps on both sides and at the top. The beneficial effect is that the flat lampshade can be well fixed on the workbench or on the assembly line through the card slot, and the installation is more convenient.

In some embodiments, a plurality of upwardly projecting fins are disposed in the middle of the top of the socket, and the fins are integrally formed with the socket. The beneficial effect is that because the LED illuminator on the LED strip generates a large amount of heat, by disposing the fins, the heat can be effectively conducted, thereby lowering the temperature, so that the power of the LED panel luminaire can be made larger. , to meet the different needs of different customers for brightness.

In some embodiments, the reflecting plates respectively form a receiving space for placing the driving power source together with the side walls on the left and right sides of the socket. The utility model has the beneficial effects that the space can be effectively saved, and the power source is placed in the accommodating space, and the whole LED flat luminaire can be made more beautiful and more favorable for standardized production.

In some embodiments, an upwardly convex heat dissipation fin is further disposed between the two accommodating spaces. By setting the heat sink fins, the heat can be effectively conducted out, thereby lowering the temperature, so that the power of the LED panel lamps can be made larger, and the different brightness requirements of different customers can be met.

In some embodiments, the top of the accommodating space is provided with a card slot, the card slot extends along the entire lamp socket, and the inner side edge and the bottom edge of the accommodating space are further provided with a through hole. The beneficial effect is that by placing the driving power in the accommodating space, the wires of the driving power source can be connected to the LED light bar and the external power source through the through holes, which is convenient and safe.
