From the above analysis, it can be seen that the utility model utilizes a high-transmittance lampshade + microcrystalline surface structure. Since the light loss is only 5%, the product function maintains a low power, improves energy efficiency, and at the same time ensures that the lamp beads are not visible from the product appearance.

[0023] Specifically, the lampshade 5 is made of PC material, which is milky white, and the reflective film 2 is white. Function: PC material has high diffusion and high light conductivity, and can be formed into a milky white lampshade, while the reflective film 2 is white to facilitate light reflection.

[0024] Specifically, the transmittance of the lampshade 5 is 84%±1%, the haze of the lampshade 5 is 96%±2%, and the reflectivity of the reflective film 2 is 96±1%. Function: With such a setting, the overall high transmittance of the lighting fixture can be specifically achieved at 95%. For example, the principle of the 95% high transmittance structure is briefly explained: 1. The lampshade material is made of PC material with high diffusion and high light conductivity, and at the same time, 84% transmittance and 96% haze (the balance point, that is, high transmittance and invisible lamp beads) are taken to maximize the light flux out; 2. The reflective film is selected to have a microcrystalline surface reflectivity of 96±1% and white color, so that the light loss of the inner cavity reflection of the light flux is 4-5%; 3. The inner surface of the lampshade is selected to have "scattered light pattern (microcrystalline surface)" to avoid high brightness in the internal reflection and increase the visual haze of the lampshade; therefore, through the cooperation of the lampshade and the reflective film, a 95% high transmittance structure can be achieved. Preferably, the reflective film 2 is a 96% high reflectivity film.

[0025] Specifically, the aluminum substrate 3 passes through the central opening of the reflective film 2, and the aluminum substrate 3 is connected and fixed to the bottom shell 1. Function: to achieve the connection between the aluminum substrate 3 and the bottom shell 1.

The LED lamp beads 4 can provide light for a long lampshade. Preferably, the LED lamp bead model is LED lamp bead 2835.

[0027] Specifically, the middle portion of the aluminum substrate 3 is fixed to the bottom case 1 by screws 6. Function: The screws can make the aluminum substrate 3 detachable from the bottom case 1.

[0028] Specifically, a surface shell 7 is provided on a side of the bottom shell 1 away from the lampshade 5, and an assembly space is formed between the bottom shell and the surface shell 7. Function: The assembly space can provide space for the installation of other components.

[0029] Specifically, the front shell 7 is a plastic front shell, and the bottom shell 1 is a plastic bottom shell. Function: The plastic front shell and the plastic bottom shell can be easily assembled and matched.

[0030] Specifically, the side walls of the face shell 7 are connected to the edge of the bottom shell 1 upward, the top edge of the face shell 7 is inclined, and the bottom shell 1 forms an angle with the bottom wall of the face shell 7. Function: The inclined shape can meet the angle of the light to adapt to the usual oblique illumination needs.

[0031] Specifically, the bottom shell 1 is oval, the lampshade 5 is detachably connected to the bottom shell 1, and the surface shell 7 is detachably connected to the bottom shell 1. Function: The oval bottom shell can better match the lampshade 5 and the surface shell 7.

[0034] The whole lamp does not come with a lampshade: the lamp beads are fully visible and no light is sacrificed;

[0035] Conventional materials + ordinary structure (i.e. ordinary lampshade + ordinary structure): although the lamp beads cannot be seen from the outside, 15-20% of the light is sacrificed;

[0036] High-diffusion and high-conductivity material + microcrystalline structure (i.e. high-conductivity lampshade + microcrystalline structure): ensures that the lamp beads are invisible while maintaining high luminous flux, sacrificing only 5% of the luminous flux;
