Introduction

There are many types of light bulbs on the market. Led lamps, incandescent lamps, and energy-saving lamps are all
mainstream light bulb products. Choosing a bulb should not only consider the quality of the bulb, but also the energy
consumption of the bulb. What is the difference between LED lamp and incandescent lamp? Are there any disadvantages of LED lights?… Read More

What is LED

The full name of LED is light-emitting diode, or energy-saving lamp for short. The LED’s high efficiency, energy saving and environmental protection and other factors quickly replaced the previous incandescent lamp. It is difficult to see the previous incandescent lamp on the market now, and the domestic and commercialization of LED is becoming more and more common, or such a magical energy-saving lamp that illuminates the earth, how does it shine?… Read More

What is Water-proof?

Protection Grade of LED lamps

Guide: with the strengthening of people’s safety awareness, the purchase of LED lamps and lanterns is not limited to lighting and heat dissipation. Dust proof and waterproof have become another demand of us.

Recently, there have been torrential rains in the south, and many places have been affected. Our lamps and lanterns are also subject to the waterproof test.… Read More

What is uniformity in lighting?

Brief Introduction

The uniformity of illuminance refers to the ratio of the minimum illuminance to the average illuminance on the specified surface. The more uniform the light distribution, the better the illuminance and the more comfortable the visual experience. The closer the illuminance uniformity is to 1, the better, otherwise the smaller the more visual fatigue.… Read More

What is beam angle?

The light emitted by the light source or lamp will not cover the entire space, because they all have a certain angle of light, that is, the range that the light of the light source or lamp can reach is limited. If three light bulbs with the same power but different beam angles are used to illuminate the same portrait, different effects will be shown.… Read More
