Embodiment approach

[0024] Based on the design of the maintenance factor, the present invention is specifically implemented as follows:

[0025] 1. Calculate the initial luminous flux corresponding to different pad temperatures and different currents

[0026] The brand-new optical design method proposed by the present invention uses intelligent control to drive the power supply of the same lamp corresponding to the constant current of the traditional method. First, use 0.7 times the current value to drive the lamp. Taking a lamp using Philips Lumileds3030 2D lamp beads as an example, test the light energy under two combinations of current and junction temperature, and then test the specific lamp from the radiator to the lamp bead. The thermal resistance of the pad, and the junction temperature value under different currents are calculated from the thermal resistance of the lamp bead specification from the pad to the junction temperature point, and the different light energies under different curr...

Abstract

The invention discloses an LED lamp-based energy-saving control method in the range from initial illumination to specific illumination. The standard illuminance set by the LED lamp is taken as a reference standard, and before the illumination of the LED lamp is attenuated to the standard illumination, current control adjustment is conducted for at least one time; after adjustment, the illumination of the LED lamp is less than the maximal illumination of the LED lamp at the moment and is not less than the standard illumination within the remaining life cycle. On the basis of the existing method which takes a maintenance factor into consideration, the method designs a brand new energy-saving method by intelligent control and through current adjustment. By the method, the energy-saving rate of LED lamp products is greatly increased under the condition of not reducing the life, the reliability or any other parameter of the products.

Description

technical field [0001] The invention relates to an energy-saving control method for LED lamps, in particular to an energy-saving control method for LED lamps within the range from initial illuminance to specific illuminance. Background technique [0002] Luminous decay is an inevitable natural characteristic of LED lamps. In order to still achieve the set illuminance within the life of the LED lamp, it is more common to add a maintenance factor to the initial illuminance calculation to increase the initial power. In this method of adding maintenance factors, the actual illuminance at the initial stage of lamp lighting is much greater than the set illuminance requirements, which will cause a lot of waste of electricity. If there is a method that can adapt to the characteristics of the LED light source and realize the control of the illuminance of the lamp from the installation of the lamp to the end of its service life, the power saving rate of the LED lamp will be greatly im...
