Background technique

LED (Light Emitting Diode, light-emitting diode) lamps have been widely used in landscape lighting, large-screen display, general lighting and other fields due to the rapid development of main technical indicators such as energy saving and long life in recent years. Compared with traditional fluorescent lamps, LED lamps have the characteristics of long life, high luminous efficiency, and low power consumption, and the light irradiated by LED lamps is relatively concentrated, so the application of LED fluorescent lamps in daily life is being gradually promoted. The global energy shortage and environmental pollution are particularly prominent in China, where the economy is developing rapidly. Energy conservation and environmental protection are issues that need to be solved urgently for China to achieve sustainable social and economic development. The annual lighting power consumption accounts for about 12% to 15% of the total power consumption. As a large energy consumer, it is necessary to find a new generation of energy-saving and environmentally friendly light sources that can replace traditional light sources as soon as possible. Compared with traditional lighting sources, LED has advantages that it does not have, such as lower power demand, better driving characteristics, faster response speed, higher shock resistance, longer service life, green environmental protection and continuous rapid development. The improved luminous efficiency has become a new generation of light source that is most likely to replace traditional light sources in the world. Although the semiconductor lighting business has just started, there are still many problems to be solved with LEDs for lighting. However, with the rapid breakthrough of compound semiconductor technology and the continuous improvement of packaging technology, the application of LEDs in the lighting field has begun to form and gradually expand. At this stage, the low luminous efficiency and high cost of luminous flux of LED are the two bottlenecks restricting its large-scale entry into the lighting field. At present, the application fields of LED are mainly concentrated in signal indication, intelligent display, automotive lamps, landscape lighting and special lighting.

In order to achieve uniform illumination of LED lights, LED lights currently have rear-projection and side-projection types.

detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the utility model.

Referring to Figure 1, the traditional common fluorescent lamp 9 (T8 lamp or T5 lamp) includes a frame 91 for installing and fixing the fluorescent lamp. This kind of fluorescent lamp emits light at 360°, and this kind of fluorescent lamp 9 must pass through the reflector. The light irradiated on the ceiling is reflected, resulting in poor lighting effect. Secondly, the frame itself is heavy and inconvenient to transport, and the light will generate heat on the frame, which will affect the normal operation of the fluorescent lamp. Due to the large energy consumption of this traditional fluorescent lamp, The annual lighting power consumption accounts for about 12% to 15% of the total power consumption. As a large energy consumer in China, these energy-intensive fluorescent lamps have gradually withdrawn from the stage of history.

In order to solve the problem of poor illumination and save costs, lampshades matching fluorescent lamps have appeared in the market. Match the lampshade with the lamp tube until the lamp tube is covered by the entire lampshade, and the light emitted by the lamp tube will illuminate the entire lampshade; The use of electricity and the improvement of illuminance will replace the fluorescent lamp 9 (T8 lamp or T5 lamp) with LED lamps. Since the divergence angle of LED lamps is 130° compared with ordinary fluorescent lamps, the divergence angle of fluorescent lamps It is 360°, so the LED light can be fixed on the ceiling, and its light is more concentrated and divergent downward. However, this method needs to cover the light board with LED lights, resulting in too strong light and high cost.

For example, as shown in accompanying drawing 2, it is a side-projection LED panel lamp 10 common in the market at present. This panel lamp is provided with LED lamps on four sides, and the side-projection LED lampshade 10a is arranged in the center of the lamp panel.
