subject: White Led Will Usher In "outbreak" Moment [print this page] However, some people feel, to use and vehicle use in the lighting so widely used in white LED, only the prices are not enough. For example, there must be inhibited to drive a white LED power supply circuit measures the power loss. Backlight for cell phones and other low-power white LED power supply circuit in the power conversion efficiency of 90%, while for the intended use of the high-power white light LED current can only reach 80%. In fluorescent lamps, the power supply circuit in the power conversion efficiency of more than 90%. That is, the loss of power supply circuits are still 2-fold difference. Using high-power white LED, need to invest a large current, also need a high heat printed circuit boards. Install the device easy to operate when the white LED is also critical.
