Angle of light Must notice when buying LED lamp its search better light Angle, make its in use process does not produce glare, such as the Angle of 20 °, light down to be in this range, the outside of the LED lamp irradiation Angle should be can't see the strong light, so as to ensure comfortable appropriate home lighting design
Led track light to shoot the light can not track meet 220 - volt power supply directly
LED track light to see your installation, if it's orbit type must orbit, orbit electricity, lamps and lanterns hang on there is a built-in power can light up. The orbits of the lamp type suction a top need to connect power after opening. The characteristics of the LED track light is moving in orbit, can change the direction of light, very suitable for clothing stores, exhibition hall and other places lighting. In the lighting CLSASELF answer for you, hope to be able to help you!

Why turn off the switch and dim the led lamp
A common cause of ED lights flashing and the solution: After turn off the power supply LED lights flashing, check the switch control is zero. If the correct wiring may refer to the following methods: The human eye can generally perceived frequency of 70 Hz light flashing, higher than the frequency does not perceive. So in LED lighting applications, if the pulse signal frequency is lower than 70 Hz low frequency component, the human eye will feel the shine. In the specific application, of course, there are many factors may lead to LED lights flashing. For example, in an off-line low power LED lighting applications, a common power supply topology structure type is to isolate the flyback topology. In accordance with the "energy star" solid-state lighting standards from line 8 w LED drive GreenPoint ? reference design as an example, as a result of the flyback voltage stabilizer sine square wave power conversion did not provide primary offset constant energy, dynamic self-supply (DSS) circuit may activate and trigger light flashing. To avoid this problem, must enable primary bias to partial discharge in each half cycle, accordingly, need to choose appropriate constitute the bias circuit of capacitance and resistance value.
