Choose good lamp bead for LED corn bulbs is very important

Lamp bead is a part of LED corn bulbs,choose good lamp bead for LED corn bulbs is very important.
Now LED lamp bead quality is uneven, as long as the raw material is a little difference, quality and cost will be sent a lot, also LED lamp bead manufacturer of packaging technology also plays a big role, take the best material such as chip to make general factory, their quality also came, not because the process, so the quality of LED lamp bead, is not very stable, often appear dead light phenomenon.
The difference between the LED lamp bead method is as follows

1. See the brightness, The drive current of 350 ma , How much is the brightness when the voltage between 3.0 and 3.6 V ? the brightness is higher, the better.

2. The chip size, the greater the chip, the better.

3. See BIN, color temperature partition and electricity of subsection BIN, the smaller the better.

4. See  Lumens depreciation, The ageing test needs to be done. Droop as small as possible. 

5. Look at the actual application, the market has the right and the price cheap lenses, aluminum plate, it is good, the lens need to open mold, aluminum plate will be put into a few bigger, 1 w power, current: 350 ma, voltage: 2.8-4.0 V, brightness: 80-130 lm, color temperature: 3000-12000 k.
LED lamp bead as the highest cost of LED corn bulbs, the dosage of the largest components, effects on the quality of the LED corn bulbs a leading role. TEK LED corn bulbs choose Cree as Lamp bead, There is no doubt, The quality of the LED corn bulbs is high quality.

What is the effect of good light bead on the LED corn bulbs?
1,Light emitting rateof good light bead is very high, led corn bulbs can reach 801 m/w, to a large extent, have played an important role in energy saving.people use led corn bulbs not only Energy saving but also environmental protection.
2, There are many kinds of color temperature, can choose according to their own needs, all sorts of color of color temperature is very good, color rendering index of led corn bulbs is also very high.
3, No radiation and infrared radiation, very impact resistance, seismic ability is very strong. People use led corn bulbs don't cause harm to human body.
4, Belong to the type of cold light, is a solid-state encapsulation, so its transportation is very convenient, are more easy to install .
5, No mercury, etc. The presence of harmful substances, environmental protection very much.

The advantage of new style TEK LED panel light is obvious

Image
TEK  LED panel light , continue to use the reflective surface luminous technology, light after secondary reflection through high light transmittance mask projection, reduce glare, the light is more soft and comfortable to the human eye to watch not easy fatigue, particularly for students who have long time exposure to indoor lighting lighting, subway passengers or office staff. The application of the patented reflective material ensures the reflection efficiency of the light, and the original high light effect of the panel light is retained to the maximum extent. In order to guarantee the reliability of the use,   the design principle of TEK LED panel light  adhering to the "maintenance", improve heat dissipation performance, reduce the LED light failure of lights and lanterns, significantly prolong the service life of the lights and lanterns, saving the maintenance cost of lights and lanterns. TEK LED panel light is more intelligent TEK LED panel light can form a

What ways can see LED street lights to replace the high pressure sodium lamp?

Image
Under the condition of current technology,luminous efficiency of  LED street lamp  is more than high pressure sodium lamp, it is an indisputable fact that TEK LED street lamp can reach 160 LM/W. And HPS spectrum is concentrated in the yellow area, its color temperature is low, only 2000-2500 k, and relatively high color temperature such as LED, LED street light natural white temperature of 4000-5000 k, cold white is 5000-6500 k. At the same time compared with HPS, LED street lamp with high color rendering index, close to natural light in the actual lighting, can bring a person the sense of comfort. Followed by "irradiation uniformity", although the  LED street lamp  lighting is relatively concentrated, but can be by the light path of the second design, can make the light source of lamps and lanterns presents the ideal state, realize the reasonable light distribution curve adjustment, control the distribution of light, so as to realize the uniformity of illumination.

Rule of thumb: what are the installation instructions of DALI LED high bay light?

Image
DALI LED high bay light , also known as LED warehouse light, mainly used in factory workshop, warehouse, exhibition hall, etc., have gradually entered homes, because it is using the latest LED lighting energy saving technology, high reflectivity, high power, high utilization rate of light source. But good lamps and lanterns need specification installation, to highlight its advantages, below for everyone to explain the DALI LED high bay light installation: 1，Define DALI LED high bay light installation height according to the lighting environment, because the environment will change the reflection efficiency of lamps and lanterns. Usually the height of DALI LED high bay light  should be above 5 meters, thread is not close to the lamp shell. If installation height is less than 3 meters, protective measures must be taken to prevent a vehicle to touch. 2，TEK DALI LED high bay light protection class is IP65, choose waterproof transformer, chip packaging place with high temperature resi
