The characteristics of the UV LED + RGB trichromatic fluorescent scheme
Advantages: Phosphors coordinate point 1) white only by their own decisions, has nothing to do with the shock hair crystal slice (discreteness can tolerate the LED chip). 2) can achieve high color reduction index RI. 3) theory is the most simple manufacturing solutions. 4) the stability of the light only depends on the fluorescent powder, can be very stable. Disadvantages: 1) leakage of uv light damage LED sealant, cause device life problems. 2) light conversion efficiency is not high, its absorption, light transmittance, etc. The challenge: 1) has not been successful so far. 2) there is no can stimulate the [...]
LED lamp bead common problems and solutions
LED lamp bead common problems and solutions 1, are the problems caused by power supply not normal: 01. Check the power supply power supply have a normal job, designator light had lit up, if there is no light up, please check the power supply have good connection; 02. Check to see if the lamp bead wire with power supply anode connection is good, is there a reverse phase, if you have the above problem, please correct connection. 2, LED lamp bead to the requirement of voltage: Nominal 3 v LED lamp bead, in fact, different color also have different requirements [...]
LED lamp lens design knowledge decomposition
On the market of LED lamp lens change rapidly, different places and different customer need optical effect also vary widely, therefore welcome the challenge of LED lamp lens design. How to design a high light transmittance, high grade, low-cost lens has become one of the main research fields of LED to shoot the light with the light. It is well known that the LED lamp product replacement fast jaw-dropping. The development of the LED lamp lens is by leaps and bounds. But on the whole, the most attention on the market or the visual effect and the whole lighting effect [...]
How to install and use Ceiling lamp?
How to install and use Ceiling lamp? (1) install the ceiling in the masonry structure, the pre buried bolt, with expansion bolts, or nylon or plastic plug plug; do not use the wedge. And the bearing capacity of the fixed parts should be matched with the weight of the ceiling lamp. In order to ensure that the ceiling lamp is firm and reliable, and the service life can be prolonged. (2) when the expansion bolt, the bolt should be selected according to the technical requirements of product specifications, the hole diameter and buried depth should be consistent with the specification [...]
TANK007 Product Change Notification of TK737 extension tube
Dear dealers and consumers, To meet the diverse needs of consumers, TANK007 TK737 can be compatible with one 18650 lithium battery (need to be installed with extension tube) and 3 AAA batteries (remove the extension tube and mount on the battery holder), but some customers reflect it is inconvenient.

Why is the highest price of LED lamps?
Why is the highest price of LED lamps? Recently, the public Liu to the supermarket to buy light bulbs, bulb shelves can let him pick hualiaoyan a superb collection of beautiful things. "In addition to the traditional incandescent and energy-saving lamps, and a LED lamp, I don't know how to lighting the lamp?" incandescent lamp, energy saving lamp, LED lamp which cost-effective? Found through experiments, home lighting or cost-effective LED lamps. LED lamp is 16 times more expensive than incandescent lamp At present, incandescent lamps are facing the situation is gradually eliminated, energy-saving lamps become mainstream in the market. The [...]
Design of side guide light LED backlight
Design of side guide light LED backlight I. Introduction As human society entered the era of knowledge economy, information and knowledge to achieve real-time, with terminal equipment to achieve the exchange of information display technology is developing rapidly, as the LCD display technology is one of the developed very fast, because LCD has its own shortcomings in no light, so most applications require supporting backlight. The backlight used is incandescent bulb, cold cathode fluorescent tube, EL and LED lamps, etc.. Each backlight technology has its own characteristics in a specific application environment. One of the advantages of LED technology has [...]
LED chip technology and domestic and foreign differences analysis
Chip is the core component of LED. At present, many domestic and foreign manufacturers of LED chip, and chip classification has no unified standard, according to the power classification, there are a large power and small power; if classified by color, mainly red, green, blue three; if the classification based on the shape, generally divided into square plate, two kinds of wafer; if according to the voltage classification, is divided into low voltage and high voltage DC DC chip chip. Comparison of domestic and foreign chip technology, foreign chip technology, the domestic chip production is not heavy technology. Substrate material [...]
