technical field

The utility model relates to electromechanical products, in particular to a large-area and high-uniformity LED module structure, especially a large-area and high-uniformity LED module structure capable of producing a rectangular projection area.

Background technique

As we all know, the general traditional street light sources are mainly incandescent lamps and halogen lamps. The principle of an incandescent lamp is to use the current to pass through the filament to generate high heat and emit light. Because the tungsten filament has the characteristics of high melting point and low evaporation rate, the filaments currently used are all tungsten filaments; in addition to the tungsten filament, there are also filled with The inert gas is used to reduce the evaporation rate of the tungsten filament to prolong the life. The main features of the incandescent lamp are low cost, good color rendering and continuous dimming; but the disadvantage is that the efficiency is low, causing most of the electric energy to be dissipated in the form of heat , so it will generate high heat when energized; the light-emitting principle of halogen lamps is similar to that of incandescent lamps, the difference is that halogen lamps are filled with halogen, and the halogen in the lamp and the filament generate a halogen-tungsten cycle, which makes it have a higher color temperature, efficiency and life. It is also higher than incandescent lamps. Due to its excellent color temperature and color rendering, as well as fairly good light collection, it is often used as a light source for accent lighting. However, halogen lamps and incandescent lamps have the same disadvantages of low efficiency and a large amount of heat dissipation, so their lifespan is not long, and the use time generally does not exceed 2,000 hours. Therefore, with the advancement of science and technology, existing street lamps have gradually replaced the shortcomings of incandescent lamps and halogen lamps with low service life by using light-emitting diodes and high-power light-emitting diodes.

As shown in accompanying drawings 1 to 3, a commonly used street lamp A has a lamppost A1, and the lamppost A1 fixes the streetlamp A on the ground. A sheet-shaped lamp panel A3 is provided, and a plurality of light-emitting diodes A4 are arranged on the lamp panel A3, and the lamp holder A2 is covered by the lampshade A5 to isolate the inside from the outside. When the street lamp A is lighting, the external power is introduced into the lamp board A3, so that the light-emitting diode A4 emits light, and the light is projected outward by the lampshade A5, so that the light is irradiated on the ground to form a projection area B. When the above-mentioned street lamp A is in use, there are still the following problems: the lamp board A3 is composed of a single board body, and a large number of light-emitting diodes A4 are arranged. Therefore, a large number of point light sources are converted into planar light sources. After area B, when the lamp panel A3 is enlarged to the projection area B according to the divergent irradiation path of the light, it can be found that the main lighting area is concentrated in the center of the lamp panel A3, and even the phenomenon of excessive illumination occurs, while the lighting projected around the lamp panel A3 Area B is relatively too dark. From the above phenomena, it can be known that the planar light source composed of light-emitting diodes A4 does have uneven illuminance, and the problem of too small projection area B exists, which needs to be improved.
