In order to solve the problems, researchers try to replace a point light source with a line light source, generally adopt a method of adding a diffusion lampshade, the diffusion lampshade can diffuse light from an LED, but because the diffusion direction is not single, the imaging of the line light source is disordered and fuzzy, the line light source is directly used for irradiating an irradiated surface, the light distribution effect is poor, the energy attenuation is more, the formed line light source is dim and disordered, and the illumination finally projected to the irradiated surface is uneven, so that the illumination effect is poor.

For this reason, researchers have proposed an optical structure of a single-direction stretching LED chip, which may be an optical film or an array of optical lenses, wherein the optical film is more convenient to use and lower in cost, but the problem of difficult fixing of the optical film has been troubling, and for this reason, researchers have proposed that the optical film is pasted on the lamp cover, but the process has a problem of damaging the optical structure due to the heating and pressing required, and how to fix the optical film on the lamp cover in a fitting manner and ensure that the optical structure is not damaged has become a goal to be achieved.
