LED street lamp, glass lens, mold opening, research and development
LED based two time light distribution design is critical to the performance of final lighting devices and products. The first part of the light, failed to achieve the effective illumination range resulting in energy loss, need high numerical aperture optical system of light gathering, further improve the utilization rate of light energy; second, after packaging, image illumination uniformity can not meet the design requirements, to the lowest illuminance is greater than the value required in the choke each point of illumination, which require the LED two optical design. Ying
The development and opening of the optical glass lens belong to the two light distribution design. In the use of LED devices, the whole system in the distribution of light intensity, temperature effect, can not meet the engineering requirements, in order to meet the engineering requirements of the LED device to send the concentrated light to the desired lighting area, so that the entire LED lighting system can achieve the desired effect. This is called the two optical design, also known as the two light distribution.
The two light distribution design must be carried out on the basis of the primary light distribution design of the LED light emitting device. Once, the light distribution design is to ensure the quality of each LED light emitting device, and consider taking the light emitted from the LED chip as much as possible. And the two light distribution design is to consider how to focus the light emitted by the LED device on the desired lighting area, so that the light energy delivered by the whole system meets the design requirements. In a sense, only the packaging design (that is, once the light distribution design) is reasonable, in order to ensure the smooth realization of the system's two light distribution design, thereby enhancing the lighting and display effects.
