- Q: LED lights it is transistor luminescence is not pure resistance filament bulbs, when dimming voltage changing, the frequency is changing so affect rectifier, sudden high voltage will burn out the LED.
- Who recommended the first floor of the answer, he was mistaken about the basic knowledge, also recommended? Three kinds of lamp, incandescent lamp the best color, color rendering index of 99 above, by contrast, it is best for your eyes, but the color temperature is too low, only 2850 k, easy to disperse. Again, it can charge.
- Q: Led lithium battery lamp, 0.5 a rated input current search. With the output of 1 a charger or mobile power no problem?
- Charging current is a bit big, easy to cause the battery heating, out in the end. Or the cause of desk lamp current charging circuit for burning.
- Q: The led rechargeable lamps useless can also be used for a long time
- Is equivalent to ordinary emergency light put a period of time. You can use it's not a problem, if unplug Light is put out that the battery is out of date in a minute. Can replace the battery, or when there is no charging function normal use.
- Q: How to distinguish whether the led lamps and lanterns glare, is there a standard?
- Glare can be divided into disability glare and arrow glare. Who reduce eye glare called a disability glare, it will be Reduce the visibility of the visual object, but not necessarily produce uncomfortable feelings; Who make the person produces the feeling of displeasure glare is called no Comfortable and glare. Cause glare of led lamps and lanterns has the following four major factors. (1) the light source brightness factor: the higher brightness, glare, the more significant. (2) light source location factor: the closer it gets to the line of sight, glare, the more significant. (3) the light source appearance size and number of factors: the apparent area, the greater the number of light sources, the more the glare, the more significant. (4) the surrounding environmental factors: environment brightness is dark, eyes adapt to lower brightness, glare also becomes more significant. Dazzling light not light, but for the concept of lamps and lanterns. Leds - t8 fluorescent lamp has been rise, are alternative Fluorescent lamp market, due to the lamps and lanterns is ready, can't change, leds - t8 fluorescent lamp needs to ordinary fluorescent effect Fruit near, thus formed the concept of glare. Anti glare products, need to consider the brightness of the led, led between the row Cloth, spacing, the led itself to the distance of the optical cover, the shape of the optical cover, light transmittance, etc., rather than simple Shell or configuration problem.
- Q: A LED light source is, but is not a plug-in, the power supply is a similar phone charger that this kind of desk lamp belongs to direct current (dc) or an alternating current, will it be a stroboscopic?
- A stroboscopic, stroboscopic degree depends on the quality of power supply. In theory, the desk lamp belongs to the direct current (dc), but after ac DianZhuan into dc, so after rectifying filtering, is not entirely direct current (dc), a part of ac harmonic superposition. Only in the battery as a power source is the real dc no stroboscopic LED light source, suggest using rechargeable LED lights.
- Q: Led charging folding desk lamp it can directly plug
- Most can't plugged directly, that kind of desk lamp without charging control circuit, as long as you don't put it down from the socket, I have been to the battery. The lamp general charging about 10 hours, evaporation of charging can lead to lead battery, the electrolyte (dilute sulphuric acid) concentration increases, serious shorten the service life of batteries.
- Q: Why my desk lamp light will keep the cell phone camera shows and white flashing light and shade stripes
- This is because, you are the light source is not continuous, it is actually in the rapid flashing, just flicker frequency too quickly, the human eye cannot perceive, so feeling is always in the light. Mobile phones, unlike the human eye, sensors are refresh regularly, when the refresh rate and light stroboscopic rate when there is a mathematical relationship, you will see the stripes, when the refresh rate and blink rate just appear a integer times, stripe can rest on the screen. This and use digital camera CRT screen will appear flashing is the same.
- Q: Are led lamps good for eyes
- Three primary colors than ordinary fluorescent eye, depends on two things: one is stroboscopic rate in the scope of the human eye is suitable for vision not eyes acid bilges feeling after for a long time; Second, the PGB tricolor high color rendering index, close to the sunlight. LED lights, the use of automatic constant current power supply, dc way, there is no flashing, so it is better than fluorescent lights. But color rendering index below trichromatic lamp, between 60-85, the three primary colors is 92
- Q: So only the halogen lamp, but is low voltage halogen lamp, need a rectifier, and halogen lamp itself temperature is high, pay attention to the heat dissipation, color rendering index selected 90-100, color WenXuan 2700 k, the best for you.
- Touch switch is a sense of application of sheet metal, unless the line on this, otherwise it will not bad. The first thing to look at you in the battery voltage is the same as in the original. In addition, it is possible that the triode inside or gate integrated piece of bad, estimate that you can't repair
- Q: Do LED lamps really protect your eyes?
- But now on the market the LED desk lamp is very much also, choose when to pay attention to whether can face light source, gradient dimmer. TOPDAY use is good
