Indoor LED lighting has experienced many years of development, and it has been difficult to enter ordinary families because of price reasons. Due to the rapid advancement of affordable LED lamp technology, the concept of affordable LED lights is widely recognized, and the LED lighting market is about to usher in the spring that meets the needs of the general public. Affordable LED lights will be able to meet the needs of the mass market, and ordinary people will be able to easily enjoy energy-saving, long-life, high-brightness and low-cost LED lights.
The design and manufacture of affordable LED lamps requires cost-effective and competitive LED light sources and LED driver power chips. Technological innovations give new fertile platforms and strong vitality to affordable LED lights. The new generation of LED light source adopts the new technology of COB and COF, and becomes a module that can reduce cost and is convenient and easy to use. The VF of HVLED adopts high voltage and small current of IF, which greatly reduces the low voltage of low voltage LED due to VF. IF high current caused by the difficult to solve the LED light source cooling bottleneck - high temperature of the lamp cavity.

MY integrated photoelectric engine system typical 5W bulb lamp (physical picture shown in Figure 2), consists of photoelectric motherboard + power sub-board. The design of the photoelectric board considers the light, electricity and thermal design of the LED light source, so that it can achieve the optimal photoelectric thermal performance. The surface-mounted LED lamp bead is distributed according to the maximum light-emitting efficiency and light distribution requirements; it does not affect the edge of the LED lamp bead. Zone, designed a linear constant current source power chip on the same side and its required resistor and capacitor layout. The linear constant current source power supply directly supplies a constant DC current to the HVLEDs lamp bead after power-on, ensuring stable and uniform illumination of the HVLEDs and ensuring reliable operation of the photoelectric engine. The main board of the power supply mainly solves the requirements of the safety requirements of the power supply part, and performs EMC processing on the power supply to prevent the impact of the power grid surge. The power sub-board has AC high voltage and needs to be protected by a high-pressure heat shrinkable sleeve. The optoelectronic motherboard must be closely matched with the heat sink corresponding to the heat dissipation area of ​​the 5W lamp before power-on. It can be electrically isolated by 3M's insulating thermal adhesive and tightly fixed with 2-3 nylon or plastic screws. Thermally conductive and not electrically conductive.

Fast Ethernet Media Converters transparently connect UTP copper to fiber. Our fast ethernet media converters provide an economical path to extend the distance of an existing network, the life of non-fiber based equipment, or the distance between two devices.with the DIP Switch. The DIP Switch can set the conversion mode (store and forward/ cut-through), the operate mode (full-duplex/half-duplex), operate speed (10/100M) and Link Fault Pass-through (LFP) function.
LFP (LLCF/LLR) can immediately alarm administrators the problem of the link media and provide efficient solution to monitor the net. LLCF (Link Loss Carry Forward) means when a device connected to the converter and the TP line loss the link, the converter's fiber will disconnect the link of transmit. LLR (Link Loss Return) means when a device connected to the converter and the fiber line loss the link, the converter's TP port will disconnect the link of transmit. Both can immediately alarm administrators the problem of the link media and provide efficient solution to monitor the net.
