Nine ways to identify the quality of LED corn bulb

Since the LED is considered to be the world's most efficient lighting, lighting lamps and lanterns industry rapid development of the fierce, also directly to LED corn bulb manufacturers and dealers have been dug up.

Because there is no uniform standard, different vendors exist differences in material selection and production technology, the resulting products are almost the same appearance, structure, function, but price differs for several times, a lot of consumer is not able to contend. Here's a look at the relevant considerations for buying LED corn bulb.

Brightness: the lighting of LED corn bulb is different in brightness, and the price is different.
372
Antistatic ability: Antistatic ability is strong, life is longer. Normally more resistant to static than 700V can be used for lighting.

Angle of illumination: In particular, special light Angle ,its price is higher

Wavelength: LED corn bulb with uniform wavelength, color uniformity, high price.It is difficult to produce pure products for manufacturers without spectroscopic chroma .

Leakage current: LED corn light is a one-way conductive lights, if there is a reverse current, is called the leakage, leakage current big LED corn bulb , short life .

Chip: different chip prices vary widely and the imported chips are more expensive.
 
Colloid: ordinary LED corn bulb steep light colloid generally for epoxy resin, with uv radiation and fire retardant added LED corn bulb light price is more expensive, high-quality outdoor LED corn bulb steep light should be uv radiation and fire prevention.

Power supply, according to the design requirements of different manufacturers, can be divided into constant current power supply and constant voltage power supply two kinds, no matter which kind of, the service life of the power supply for whole lamp plays a central role.If the lamps are broken, they are usually burned out.

Radiators, can see the appearance of lamps and lanterns, if the external or internal of lamps and lanterns is made of aluminum, could solve the thermal effect of lamps and lanterns so as to achieve better prolongs the service life of lamps and lanterns, temperature on the service life of LED corn bulb light lamp bead plays a critical role.

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
