Do you know anything about big panel lights?

Backlit panel light

LED panel light is a high-grade indoor lighting fixture, its outer frame is made of aluminum alloy by anodic oxidation, the light source is LED, and the whole lamp design is beautiful, simple, luxurious atmosphere, not only good lighting effect but also can bring people the feeling of beauty.

LED panel light design is unique, light through the high transmittance light guide plate to form a uniform flat luminous effect, good illumination uniformity, soft light, comfortable and bright, can effectively alleviate eye fatigue. LED panel lights can also prevent radiation, and will not stimulate the skin of pregnant women, the elderly, or children.

However, do you know about big panel lights? Let’s learn a little about its construction and knowledge now.

Classification of LED large panel lights

LED panel light design is a beautiful, simple, luxurious atmosphere. With its good uniformity of illumination, uniform and soft light, and comfortable lighting effect, it can effectively relieve eye fatigue, is widely used in offices, schools, hospitals, shopping malls, home,s and other places.

LED panel lights have two types: side light and straight down (straight light), which must be used with driving power.

Installation methods include project money (embedded, lifting), integrated ceiling, and surface installation.

LED panel light structure

LED side light panel light mechanism and light principle:

LED light bead light from the light surface into the light guide plate interior, light beam into the light guide plate after the light beam down, from the luminescent surface of the light irradiation, not the light beam to the light point will be reflected through the reflective film, so the bright part of the LED light bead into the light used for lighting. The quality of the light guide plate is an important standard to measure the quality of the side light panel light.

Structure and luminous principle of LED-backlit panel light:

The structure of backlit panel light mainly includes a frame diffuser panel light strip (including aluminum base panel light bead lens) back cover.

The light of the LED bead is emitted from the luminescent surface of the light through the lens scattering and back cover reflection

Components of LED large panel light

1. Frame:

Frame strength affects the durability and overall texture of the light.

The frame is an important part of the panel light, and the high-strength frame makes the panel light more durable. The side frame of the LED panel light uses different materials, and its heat dissipation performance is not the same.

At present, the frame materials of the panel light mainly include aluminum alloy, steel, PC, A6063, aluminum plastic, steel, and other materials. The most commonly used aluminum frame color is sprayed white and brushed silver, and for splicing and welding frame, the welding frame will be more firm, and the price will be higher than the patchwork frame. A general frame according to the style of a flat frame, or step frame, the price will be different. In addition, the gram weight of the frame (how much material is used) will also affect the price.

2. Back cover:

Commonly used is the iron back cover, the thickness of the gram weight is different, and the strength is different.

The straight-down panel light is different from the side light panel light, the back cover is thicker, and the straight-down back cover will be sprayed or coated, in addition to coloring to better reflect the light.

Common thicknesses are 0.18-0.16/0.2-0.18/0.25-0.23/0.27-0.25/0.3-0.29 mm.

3. Diffusion plate:

Different materials have different transmittance. The role of the diffusion plate is to evenly disperse the light of the light guide plate, but also to play the role of fuzzy dot, the use of materials mainly PC, acrylic, PS, PP and so on. From high to low prices, PS and PP are used more.

PS diffuser plate thickness of conventional: 0.5/0.6/0.7/0.8/0.9/1.0 mm
Acrylic transmittance is 92%, PC is 88%, PS is about 80%, acrylic transmittance is higher than PC, and the cost is lower, at the same time its anti-aging performance is weak; And PC material is expensive, but strong anti-aging performance.

4. Light chip:

The service life of the low voltage LED strip light is 50,000-100,000 hours. In practice, it can reach 30,000-50,000 hours. Because of the high voltage, the heat output per unit length of the high voltage LED strip light is much more than that of the low voltage LED strip light, which directly affects the life of the high voltage LEDstrip light. Generally speaking, The high voltage unit has a 10,000 hour service life.

5. Light guide plate:

The plate, in addition to the lamp bead has a great influence on the light effect.

The light guide plate is a component of the side light-emitting panel lamp. The function of the light guide plate is to refract the light from the direction parallel to the light transmitter plate to the direction perpendicular to the light transmitter plate, and the light refracted from the light guide plate to the back of the panel lamp is reflected by the reflective paper (PET/PP).

In this process, but also as much as possible to reduce the light decline, generally speaking, the light efficiency of the light guide plate largely depends on the dot design, followed by the choice of the plate (transmittance).

The commonly used plate is PMMA, MAS, and PS. The price goes from high to low. However, PS and MAS will produce yellowing after prolonged use; PS will last about two years, and MAS will last a little longer in three years, which also depends on the regional climate; generally speaking, hotter places will require shorter yellowing time. If you want 5 years warranty or higher light efficiency, basically will use PMMA light guide plate. The size of the light guide plate used by various factories is generally in the range of 1.6-3.0mm; the thicker the price is higher.

6. Driving power supply:

Prices vary according to brand, voltage, isolation/non-isolation, strobe or not, functional requirements (e.g., dimming and color wifi) and certification requirements.

7. Anti-glare board:

Anti-glare is required. 19 not dazzling), need to add a prism plate or anti-glare film before the diffusion plate.

Advantages and disadvantages of back panel light and side panel light:

The side light panel lamp has the advantages of a beautiful, simple, luxurious atmosphere, uniform, soft glow, ultra-thin thickness, convenient installation, transportation, etc. The disadvantage is that it is not easy to achieve high light efficiency, and the current 120Lm/W is very expensive. In addition, PS and MAS light guide plate panel lights for a long time, there may be yellow.

The advantage of the bottom light panel lamp is that the technology and process are relatively simple, and the semi-automatic production line makes the labor cost lower. Sufficient brightness and easy to achieve high light efficiency, currently can do 135lm/w, the lamp basically will not yellow, the price compared to the side glow has an advantage; The disadvantage is that the lamp will be thicker, it looks less high-grade than the side light panel lamp, and the packing volume and freight will increase. Because of the empty structure, compared with the side luminous panel lights, the transportation requirements are higher. Some straight-down panel lights will have dark areas at the edge of the frame, mainly the style of a beveled back cover. There is a rectangular edge style of the bottom light panel lamp, no dark area, and light uniformity is better.
