Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?
Look at the LED in the LED bulb. Several LED are connected in series. Several groups are connected together, and then the voltage is estimated. Then the power of the bulb is divided by the voltage of the LED bulb to calculate the required current. Select the appropriate LED drive circuit. The average USB output current of the computer is only 100mA~500mA. The power is not enough to make the LED light achieve normal brightness, or it may damage the USB interface. It's better to use the USB charger interface. DIY needs circuit knowledge.
Q:What's the reason for the LED bulb strobe?
If this resonant characteristic causes the input current to fall below the TRIAC sustaining current, the TRIAC will turn off. After a short delay, the TRIAC usually switches on and fires the same resonance. In the 1.5 cycle of the input power waveform, this series of events may be repeated several times to form visible LED flashes. To cope with this problem, a key requirement of TRIAC dimming is that the input capacitance of the EMI filter is very low and that the capacitor is decoupled through the TRIAC and the winding impedance. According to the formula, if the capacitance of the dimming module is reduced, the resistance of the resonant circuit can be increased, and the oscillation is suppressed in principle, and the desired circuit work is resumed.
Q:Is it possible to manually weld LED bulb bulbs?
You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off
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?
With the temperature of the heat sink to judge a lamp is not easy, the domestic aluminum radiator are generally more, for T8T5 will have to see the size of the whole lamp power, the simplest is to look at the weight, the relative materials generally heavier will be better.
Q:Why can't the voice switch control the time of the LED bulb?
Current problem. The current is too weak. You don't have to use an electric meter to see if you can work properly without a light bulb. Change the timer switch.
Q:How does the LED bulb look good or bad?
Power supply must be constant current power supply. This must, do not have that resistance. The constant current source resolution methods, there is no power is apart of a 8 foot IC, if not, no junk to, also not all the IC are good stuff, a famous lighting city have specialized quality of constant current power supply.
Q:LED bulb PC, will the white cover affect the color temperature of the finished lamp?
PC Ivory lampshade, because of the low price, it is recommended to use light diffusion cover, so this should not be the problem
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:How to identify Ic constant current LED bulb?
Hello, LED market is now very confused, this problem is the use of LED lamps of the users are more concerned about the problem, the so-called IC constant current drive power refers to the LED lamp (commonly known as the transformer) with a constant stream of multifunctional IC chip, the IC is generally 5-8 feet (depending on the model and decision scheme), role is to ensure that the current through LED lamp is controlled in a relatively constant parameter, ensure the long-term stability of LED lamp work at constant current. When the input or output voltage is changed, the current through LED remains constant, so the constant current IC of the LED light stability and service life is directly related to the IC also includes internal short circuit protection, overtemperature protection function of open protection etc.
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
