Zhongshan Guzhen led ceiling lamp module manufacturer JIAYE optical LED lamp lens/reflective cup is used for focusing and guiding light of high-power LED light source series products. LED lamp lens designs the light distribution curve according to the angle of light emitted by different LEDs. By increasing optical reflection, reduce light loss and improve light efficiency (aspheric optical lens is set). Plastic materials used in injection lens products have the following advantages: high production efficiency (can be completed by injection molding); High light transmittance (about 93% at 3mm thickness); Disadvantages: temperature resistance: 70% (thermal deformation temperature: 90 °); Optical grade PMMA (polymethylmethacrylate, commonly known as: acrylic)

the cup lens of JIAYE optics uses a point light bulb as the light source, and the LED ceiling lamp module requires a reflector for long-distance spotlight, which is usually cup-shaped, commonly known as the cup lens. There are three basic conditions for the spotlight of the cup lens: the point power bulb of the cup lens. The smaller the illuminant of the light source, the better the condensing property. Precision multi segment focusing reflective cup. Precise concentric positioning structure of bulb. Generally, the light energy of the light source to meet the growing demand for such forward-looking materials will be fully radiated in the 360 direction. In order to effectively use the limited light energy, the lamp can control the illumination distance and illumination area of the main spot through the light reflector. A device that reflects light in a lamp. According to different sizes and shapes of light sources and different lighting requirements, light reflectors can be made very simple or precise

the manufacturer of JIAYE optics' ultra-thin straight lens and led ceiling lamp module includes two free-form surfaces, which respectively form the incident surface and the emitting surface; The shape of the free-form surface lens is determined as follows: take the LED light source as the origin o to establish a space rectangular coordinate system, take the plane of the LED bottom as the plane, and take the axis passing through the origin and perpendicular to the plane as the axis, first divide the solid angle of the light source, and divide the area with the maximum lighting lifting weight of 72 tons on the target lighting surface into rings, and then use the law of conservation of energy to establish the mapping relationship between the solid angle of the light source and the ring area on the target lighting surface, Then using the law of refraction and reflection, the final double free-form surface lens is obtained through the geometric relationship. The invention is small in size, and after the light emitted from the LED passes through the double free-form surface lens, a circular spot with uniform illumination distribution can be formed on the target illumination surface, and the output efficiency of the lens is very high

JIAYE optical panel lamp module lens, Zhongshan Guzhen led ceiling lamp module includes a plurality of free-form surface optical lenses, which are arranged according to the module size of the straight down LED backlight system. The free-form surface optical lens is an ultra-thin straight down led free-form surface optical lens, which makes the light emitted by the LED light source form a rectangular spot with uniform illumination on the screen, And the distance between LED light source and screen is less than or equal to 30mm. The utility model does not need other auxiliary devices for light distribution, reduces the loss of light energy by the light distribution system, improves the utilization rate of light energy, and meets the ultra-thin design requirements of the large-size direct down backlight system and reduces the cost. In addition, there is a hemispherical cavity in the middle of the bottom surface of the lens for the led to be installed, which makes the LED light source and heat dissipation device easy to install, and is conducive to improving the heat dissipation efficiency of the whole backlight system

according to the use of flashlight, there are also eight members of the Association - four of the five global MDI manufacturers - and the environment of six other companies is different. There are many models of LED ceiling lamp module manufacturers, so different models of flashlight need to be equipped with different lenses. It is necessary to determine the matching method of different lenses according to different application occasions. The specific preconditions are: whether to choose a single square lens to customize one-to-one, JIAYE optical square module lens to customize, or multi head lens module; The distance to be illuminated is different from the planning, and the corresponding focusing angle is determined; Determine the diameter or height of the flashlight lens according to the different specifications of the flashlight; According to different brands of light sources to determine the corresponding flashlight square module lens customized. In what has become a very popular photo function, JIAYE optical square module lens is customized, but its development seems to be close to the limit. It is getting thinner and thinner, but some components are difficult to be lightweight

in the non imaging optical design of LED street lamp lens of Zhongshan Guzhen led ceiling lamp module, the basic optical elements mainly include lens, aspheric reflector and refractive plate. Through the introduction of the project mirror, the light emitted by the point light source can converge or diverge, and play the role of changing the beam angle, so as to achieve the purpose of changing the lighting area and illumination value of the illuminated surface. The shape of aspheric mirror is usually a rotating quadric surface, and its working principle is completely different from that of lens and mirror. The lens uses the principle of refraction, and the mirror uses the principle of reflection or total reflection. Their aperture angle is generally below 40 degrees, while the aperture angle of aspheric mirror can reach more than 130 degrees, that is, its ability to collect light can be greatly enhanced As for the main function of the refraction plate is to change the direction of light or the angle of light beam in a specific direction, in fact, it is the common and familiar peripheral plastic panel of LED street lamp lens. This plastic panel is classified according to the structure, mainly including toothed refraction plate, trapezoidal refraction plate and cylindrical refraction plate
