LED PANEL LIGHT Structural Analysis
LED panel light because of its stylish simple appearance, high light efficiency, no glare, etc., has become the LED lighting industry one of the most popular products. LED panel lights have become the most widely used commercial lighting in modern lighting one of the products.
1. LED panel light frame
The face frame is one of the LED panel lamp housing components, mainly used for LED panel lamp cooling channel. Its design is relatively simple, the current market generally use aluminum or plastic as a frame material. Aluminum type of frame with abrasive stamping, mold and processing costs are low, there is a die-cast aluminum frame IP level can be higher, the surface texture is good, the overall appearance, but the higher cost of pre-injection mold. Some LED panel lamp manufacturers in order to save costs, or for different market considerations, will also use plastic frame, the advantages of this surface material is to save costs and improve the safety of LED panel lights.
2. LED panel light source
And other similar LED lamps, panel lights in the choice of light above the market mostly 2835 and 3528 SMD lamp beads, the future With the LED industry, LED light source will be more choices.
3. LED panel light guide plate
Light guide plate is the key to LED panel light quality control. To LED panel lights in the light performance on the performance. Light guide plate material and network design is the key. Currently in the market, qualified light guide plate is relatively mature, and its relatively relatively light transmittance. The key lies in the design of the light guide plate, the network design is not good, see the overall light effect is very poor, the general will appear on both sides of the dark side of the dark, or there is light into the light band, or visible local dark area, or Different angles are inconsistent.
4. LED panel light diffusion plate
Diffuser plate in the LED panel lamp components play a role is to light guide plate light evenly derived, but also play the role of fuzzy network. Most of its material is made of acrylic 2.0 sheet or PC material.
Acrylic cost is lower and the transmittance is slightly higher than the PC, acrylic brittle anti-aging performance is weak, PC prices are slightly more expensive, but anti-aging performance. Diffuse plate can not be seen after the installation of outlets, and the light transmission rate to about 90%. The acrylic transmittance was 92% and the PC was 88%.
5. LED panel light reflective paper
The role of reflective paper in the LED panel lights is mainly to improve the light efficiency, the role of the principle is to light the back of the light guide plate to reflect the excess light to improve light efficiency.
6. LED panel light drive power
There are two kinds of LED drive power, one is the use of constant current power supply, this mode is high efficiency, PF value of up to 0.95, cost-effective; second is the use of constant pressure with constant current power supply, stable performance, but low efficiency, high cost, This power is mainly exported, the other request for certification requirements, the need to use safety power. In fact, the use of household constant current power supply is very safe, because users are difficult to access to power, and the lamp itself is the use of safe low voltage.
7. LED panel light mounting parts
In addition, LED panel lights, such as mounting parts such as hanging wire, screws, mounting bracket for the installation and fixing of panel lights.
