Q:LED bulb with what type of LED beads?

The LED bulb is mainly white and warm white two colors are white, the temperature is generally 6000-6500K color, the color of the sun light at noonWarm white temperature is 2700-3000K, yellow, similar to the sunset color temperature.

Q:Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!

Plastic bulb lamp, I have done it myself, this gadget specializes in low-end market, it is recommended not to use, used well, used for a long time, used poorly, minutes of effort have to hang.

Q:Ordinary lamp LED bulb can?

Absolutely, without any effect. It can be directly across to look at the opening of several inches.

Q:What is the 15 Watt lumen of the LED bulb?

Each brand has different bulb qualities, probably around 1W between 60-85LM/W.

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:What's the difference between a glass cap for a bulb and a PC hood?

1, impact strength comparisonPC and glass is the biggest difference resistance shock, PC is transparent plastic, the most resistant to impact, smashing not broken.Similarly, PC is 200-300 times the impact resistance of glass. PC is 30-50 times the impact strength of PMMA acrylic.

Q:Detailed description of LED bulb lamp

Healthy LED is a green light source. The LED lamp is driven by DC without flicker. Without infrared and ultraviolet components, without radiation pollution, it has high color rendering and has a strong luminous directionality, good dimming performance and no visual error when the color temperature changes

Q:What's the reason why LED bulb gets a lot of heat?

If the radiator has a large radiating area, the temperature is low

Q:What does the LED bulb patch mean?

Performance of LED patch lamp:1, micro power consumption: LED lamp, 2W brightness is equivalent to 40W incandescent brightness, 3.6W brightness is equivalent, 60W incandescent brightness, brightness in the middle stronger.2 、 voltage adaptation range: nominal 220V lamp.3 、 the light distribution technology expands the LED point light source to the surface light source, increases the luminous surface, eliminates the glare, enhances the visual effect and eliminates the visual fatigue;4 、 lens and lampshade integrated design. At the same time, the lens has the functions of light gathering and protection, thereby avoiding repeated waste of light and making the product more concise and beautiful;5 、 high-power LED flat cluster package and radiator and lamp holder integrated design. The LED heat dissipation requirement and the service life are fully guaranteed, and the design of the LED lamp structure and the shape are completely satisfied, and the LED lamp has the distinctive characteristics of the lamp;6, Aluminum Alloy lamp body and the overall molding process, to ensure a good cooling effect, reducing the effective use of LED in the process of decay.7 、 no strobe. The pure DC work eliminates the visual fatigue caused by the strobe of the traditional light source; and the environment is green. No lead, mercury and other polluting elements, no pollution to the environment;8, impact resistance, resistance to leilijiang, no ultraviolet (UV) and infrared (IR) radiation. No filament and glass shell, no fragmentation of traditional lamp, no harm to human body, no radiation.

Q:What does "A19" mean in LED A19 bulb?

A19 is the European A60: represents the outer diameter 60mm=19/8*25.4=60.325mm, such as the diameter of the A19 bulb. "D=19*1/8", multiplied by 25.4, is the diameter of the bulb in mm units. The source of this formula is the same as the T8 tube: "X" in Tx means that the diameter of the tube is x times 1/8 inches, so the diameter of T8 is 1/8 inches x 8=1 inches, or 25.4mm
