1, independent of the external control device
Although the recessed downlight fixtures are generally used for indoor, there is no IP protection problems, but non independent type an external control device, often caused by electric shock proof requirements and external requirements of wire and external wire fixing requirements of unqualified luminaires.
2, control device for non SELV, LED no shock protection
In order to make the LED have good cooling conditions, LED insulation and heat radiator are often not up to the voltage level of the insulation requirements, in accordance with the safety standards, the output voltage of only LED control device for safety extra low voltage (SELV), namely LED control device input and output using isolation measures, and the output voltage between the two poles, and each pole of the output voltage is not greater than 50V. So, in order to reduce the output pole with protection against electric shock LED.
The main security problems of embedded downlight lamps
3, the control device and the light source cavity of the cable does not meet the requirements of external wire
Because the control device is not installed in the lamp, so the connection cable control device and the light source cavity belongs to the external conductor, designers of many enterprises do not know this requirement, thus causing the connection cable does not meet the requirements of the external conductor.
4, exposed wire but no cord fixed frame
Because the control device is not installed in the lamp, the connecting cable of the control device and the light source cavity is exposed outside. Standard lamp, wire exposed more than 80mm, these wires must have cord fixation to assume these external wires may be external torque and tension in the control device and the light source cavity parts, but the designers of many enterprises do not know this, none of the parts of the design and installation of wire fixation.
