High-quality LED panel lights, the cost is spent here
LED panel light is a high-end indoor lighting fixture, generally used in large offices, hotels, shopping malls and other places. The design of the whole lamp is beautiful, concise and luxurious, which not only has good lighting effect, but also brings beautiful feeling to people.
However, some panel lights on the market are thick and heavy, some are light and simple, and the quality is also very different. Today I am going to reveal the mystery to you all.
There are two kinds of lighting methods for panel lights on the market.
That is, side-emitting and positive-emitting.
The main difference between the two is whether there is a light guide plate.
The side-emitting panel light uses the light guide plate (PMMA) technology to design the dots of the light guide plate according to the arrangement of the lamp beads of the LED lamp board and the light-emitting angle of the lamp beads, so that the light can pass through the light guide plate to achieve the effect of uniform brightness. Around 93 percent . The thickness of the lamp is 8mm-12mm, which can be used in occasions with low ceilings.
The positive emitting panel light has no light guide plate, and the price is relatively cheap. Since the number of lamp beads is large and the interval is relatively large, the distance between the lamp beads and the PC diffuser must be relatively large, so that a dark area will not be formed when lighting, so the thickness of the lamp is generally about 3.5cm-5cm. Compared with side-emitting lamps, it is much thicker, bulkier and heavier, but the light transmittance is relatively good.
The light emitted by the side-emitting panel lamp beads is reflected by the reflective film of the light guide plate and then irradiated. After passing through the light guide plate, there will be a certain loss of luminous flux. This is why the light transmittance of side-emitting panel lights is not as good as that of positive-emitting panel lights.
However, a good diffuser plate makes the light incident on the plate get sufficient diffuse reflection and refraction at different angles, and has the optical characteristics of high diffusivity, high haze and high transmittance, and can effectively convert point or line light sources into soft , Uniform surface light source, and in terms of light transmittance, there is little difference compared with positive light-emitting panel lights.
Unique optical design, the light passes through the light guide plate to form a uniform plane luminous effect, no dark areas, and high light output efficiency, greater than 80LM/W.
Pure aluminum frame, brightened silver treatment, good heat dissipation. The corners are seamless, the appearance is simple and stylish, and it will never change color. Excellent thermal management can effectively ensure the long-term stable operation of the LED light-emitting tube.
Using constant current power supply, stable and durable, 40,000 hours lifespan, beautiful and generous, can also be used as a decoration without turning on the light.
The panel is made of high light-transmitting acrylic sheet, which requires no accessories for embedded installation, consumes less power and saves costs.
Instant lighting, no stroboscopic, no glare, no lead, mercury and other harmful substances, no ultraviolet rays, etc., environmental protection and safety.
The luminaire is easy to install, and it can be directly replaced by the ceiling for embedded installation; it can also be hoisted by using the hoisting holes on the back of the luminaire; or it can be matched with a ceiling frame for ceiling-mounted installation.
The light-emitting angle reaches 120 degree , and the light is smoother, softer and more uniform.
