Q:How does the lamp line connect
The one that used to be in the early part of the world, which requires the regenerator to cooperate with the light, is an inductance ballast, and the fluorescent tube now needs to glow without the regenerator. The ballast that doesn't need a regenerator is an electronic ballast. Ask to sell tubes of the owner, they all know and electronic ballast inductance ballasts, now basically eliminated inductance ballasts, everybody understand the electronic ballast is enough. If it is an old lamp, it will meet the inductive ballast. The lamp tube has two feet on each side, and the left and right sides are four feet
Q:What is the reason for the movement of light in the tube
Lamp tube problem, get a hot towel tube to wipe, sometimes can solve.
Q:An electric power saving device installed on an old-fashioned daylight lamp tube
Make a voice-controlled circuit to control the power switch.I hope my answer will help you.
Q:Put on the new light bulb, why the lamp still not bright
Does your fluorescent lamp use a inductive ballast or an electronic ballast? Is the newly installed lamp tube not bright or filament red but unable to start? If the inductor is completely unlit, check to see if it is installed
Q:The lighting is replaced by LED lights and circuit problems
LED bulbs have special or built-in support, which is completely different from the old fluorescent lighting fixture. The suggestion is that the old stents can be recycled.
Q:What are the advantages and differences of the LED panel lights?
From the perspective of the light-emitting LED flat light mainly include side glow and are currently two emitters design, each have advantages and disadvantages of two kinds of light way, is shining on the structure and side shine without guide plate, is the difference between a positive light panel light has the advantage of the same light bead cases higher luminous flux, because the light-emitting panel lamp lights, side shine after reflection of light guide plate need to illuminate, after guide plate has LED to the loss of the luminous flux,
Q:Does the LED lamp need to be a national compulsory certification
Do not need, at present domestic do not have mandatory certification, domestic also do not have a unified standard and index! At most, there is the certification of the eu system, ce and rohs. In fact, leds are the most energy-efficient way to make a comparison: We compare 1.2 meter ordinary fluorescent lamp with 1.2 meter LED fluorescent lamp consumption By 20 hours per day: The average fluorescent lamp has a life expectancy of two years, LED fluorescent bulbs have an average life span of six years (the LED fluorescent tube has a lifetime of 4,3800 hours). The 12WLED fluorescent lamp is comparable to a 40W standard fluorescent lamp.
Q:The same thing is 5w, is this LED tube power or is this a fluorescent lamp?
Power consumption is the same, but brightness is different.The fluorescent lamp is good for people's eyes, LED saves electricity, oneself choose.
Q:Which is better? In terms of power and price
I think this brother is not very clear about leds; In fact, the lamp contains the way of the patch Led lamp bead classification 1. Straight insert small power specifications are as follows: straw hat/helmet, round head, concave, ellipse, tombstone type (2 * 3 * 4) bullet, flat head, type (3/5 / flat bread) piranha, etc. 2. SMD patches are usually divided into (3020/3528/5050, these are positive luminescence) / 1016/1024, and these are the lateral luminescent sources. 3. Large power leds are not classified into the patch series, their power and current usage are different, and the photoelectric parameters are very different. Single single high power LED light source, such as no heat dissipation base (generally for hexagonal aluminum), its appearance and the average patch without too big gap, high power LED light source is circular, encapsulation mode basic and SMD patch is the same, but with SMD patch in the conditions of use/environment/effect has essential difference. Photosynthetic efficiency as to what you say, he is equal to the luminous flux/power is the power points, as we have 3014 (0.1 W), 3528 (0.06 W), 2835 (0.5 W)... The flux is also the customer's requirement, we have 5 to 60 lm here, of course the price is different. Hope is useful to you
Q:The circuit board in the LED fluorescent tube, what's the name of the component?
I don't know what you're doing with your electrons, and I'll give you three days to complete the schematic. Just like your boss says, don't let it go.
