- Q: LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
- You should say that the bulb of the bulb, usually PC material.
- Q: LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
- It is best not to direct contact with glue, glue because the thermal conductivity of aluminum than a lot of difference, even a thin layer will reduce the heat out of the speed of the screw can be used to aluminum plate and aluminum fastening together, the contact surface is smooth, when necessary, can use some conductive silicone grease amount
- Q: LED bulb with what type of LED beads?
- There are many LED bulbs with LED lamp types, different lighting manufacturers will adopt different LED models, at present, most of the 2835, 5730 beads, beads are 0.5W-1W LED beads, specific type: PL-P2835DW-C8-R3-C2/ PL-P5730EDW-C8-R3-C2
- Q: LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!
- How many seconds delay? It won't take so long. How many bulbs do you usually soak in 0.5 seconds? A squeaky noise is usually a transformer or inductance whistle, and at least it shows a poor manufacturing process.
- Q: LED what kinds of screw bulbs are there?
- Ordinary bulb is the most common, is a metal electrode which is threaded, so it requires that one electrode when installing the socket contact thread to pick the zero line, the middle dot electrode lamp power. Otherwise, an electric shock occurs when an accidental contact with the exposed metal. Because of this symmetrical way, the bulb can be threaded to fit the socket.
- Q: What are the requirements of the LED series inspection specification for bulb bulbs?
- Insulation resistance: the lamp should not be placed for 48 hours in the damp box with relative humidity of hours. The air temperature in the box shall be controlled at any value between 20~30 degrees centigrade, and the temperature difference is within 1 degrees. The insulation resistance shall be measured in the wet box. Now the DC voltage on the lamp is about 500V. After 1min, the insulation resistance test will begin. The insulation resistance between the lamp holder, the current carrying metal parts and the accessible lamp parts shall be no less than 4M ohms.
- Q: What is the AC voltage of the LED bulb?
- The AC voltage of LED bulb is usually 220V, and the power is divided into 3W, 5W, 7W, 8W, 9W, 12W and so on.The biggest market for LED bulb lighting is the civilian market, and the LED bulb is a new green light source to replace the traditional incandescent bulb. LED lamp has the advantages of energy saving, environmental protection, long service life, no stroboscopic, green and so on.
- Q: LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
- If it is to continue the glimmer of minutes, the main side is the use of resistance and step-down circuit caused by the normal phenomenon. It's very rare for the factory to use this old model to make LED balls. Circuits that run for hours or all day on the side of the LED bubble are out of order. It's not normal to shine for so long. Now most of the LED bulb is using IC constant current supply circuit, no such situation has emerged.
- Q: What advantages does LED bulb replace energy saving lamp?
- LED lamp structure is strong, green environmental protection, not easy to destroy, long life (generally 5 years is not a problem), this is energy-saving lamps can not be compared
- Q: Why can't the voice switch control the time of the LED bulb?
- Originally white silk lamp, later replaced by LED bulb, with a light activated switch control, replaced by LED bulb, the lamp does not extinguish for 30 seconds
