Detailed Description

In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

As described in the background section, currently, in order to improve the uniformity of the light emitting surface, a plurality of LEDs are combined into an LED array to improve the uniformity of the light emitting surface. However, since a plurality of LEDs are required, the cost is high, the uniformity of the light emitting surface cannot be made high, and the power supply for driving the plurality of LEDs is also required.

In view of this, the present application provides an LED uniform light lamp, please refer to fig. 1, and fig. 1 is an explosion structure schematic diagram of the LED uniform light lamp provided in the embodiment of the present application, the LED uniform light lamp includes an LED light source 1, a lampshade 2, and a uniform light film 3, the LED light source 1 is located at the bottom of the lampshade 2, and the uniform light film 3 covers the top opening of the lampshade 2.

Preferably, the lampshade 2 is a wedge-shaped lampshade 2, the light gathering effect is best, and the uniformity of emergent light is best.

Optionally, in an embodiment of this application, lamp shade 2 is mirror surface aluminum lamp shade 2, and mirror surface aluminum lamp shade 2 is light in weight, and mirror surface aluminum lamp shade 2 is strong to the reflection effect of the light that LED light source 1 sent, prevents the absorption of lamp shade 2 to the light, and then makes the even light lamp of LED strengthen luminous intensity under the prerequisite of guaranteeing that the emergent light is even. However, the present application is not limited to this, and in other embodiments of the present application, the lamp housing 2 may also be a plastic lamp housing 2 with a chrome-plated inner surface.

Preferably, the depth of the lampshade 2 is more than 15 mm, the divergence angle of the light emitted by the LED light source 1 is generally 120 degrees to 140 degrees, if the depth of the lampshade 2 is too small, most of the light is directly emitted from the top opening of the lampshade 2, and a small part of the light is emitted from two sides of the top opening after being gathered by the inner surface of the lampshade 2, so that the brightness of the middle area is higher than that of the other areas, and the uniformity of the light emitting surface is poor.
