Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?
If the material with better thermal conductivity, the lamp shell about 60 degrees is best.Reason:1: if the temperature is too high, that your radiator is too small.2: if the temperature is low, indicating that your calories did not lead out. (of course, if the radiator is too large and the temperature is low, but the bulb and tube are too heavy to pass by certification)
Q:Led what's the flash of the bulb?
So, this is the power overheating protection at work. It will not be the case if the outer shell is enlarged or the room is ventilated and the heat should be cooled.
Q:LED bulb PC, will the white cover affect the color temperature of the finished lamp?
In the integration sphere measurement, there is no standard lamp to proofread, or something else in the interior affects the measurement result, for example, the color of the lamp body itself will affect the color temperature more or less. Single color beads, chip on the aluminum base?
Q:In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate
The standard is the body temperature of the LED lamp. With a multimeter probe is placed in the LED lamp bulb angle can be measured temperature. Generally -20~80 degrees centigrade
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
Q:What does the LED bulb patch mean?
According to different applications, different size, cooling scheme and luminous effect of.LED packaging forms. At present, according to the classification of LED package are mainly Lamp-LED, TOP-LED, Side-LED, SMD-LED, High-Power-LED, Flip Chip-LED Lamp-LED (vertical LED) emerged in the early Lamp-LED is in line LED, it adopts the form of sealing packaging. The potting process is the first injection of liquid epoxy resin in LED molding cavity, and then insert the pressure LED bracket welding, in the oven make epoxy resin after curing, the LED from the cavity from the molding. Due to the relatively simple fabrication process, low cost, have a higher market share. (SMD-LED surface mount LED) patch LED is pasted on the surface of a wiring board, suitable for SMT processing, can be reflow, a good solution to the brightness, perspective, smoothness, consistency, reliability and other issues, the The lighter PCB plate and a reflecting layer material, improved to remove the carbon steel pin dip LED heavier, the display of epoxy resin less reflective layer needs to fill, to reduce the size, reduce the weight. In this way, the surface mount LED can easily reduce the weight of the final product in half, make the application more perfect.
Q:How did the trademark on the LED bulb go up?
Laser printing and screen printing, pad printing can be, look at the needs and equipment.
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:LED bulb bulbs, do you need 3C certification now?
Simple bulb does not require 3C or CQC certification.Only with lampholders, and then judge according to the situation.
Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
4 and three is different. An incandescent lamp relies on heating the electrode wire to send out visible light. The energy-saving lamp releases the electrons by conducting the electrode wire, while the LED light is led by the diode.
