The LED panel light has a unique design. The light passes through the light guide plate with high light transmittance to form a uniform plane luminous effect. The uniformity of illumination is good, the light is soft, comfortable and bright, which can effectively relieve eye fatigue. The LED panel light can also prevent radiation and will not irritate the skin of pregnant women, the elderly, and children.
1. Frame and bottom plate
The heat dissipation performance of the LED panel light's frame and base plate is different according to different materials, and the price is also different.
2. Light guide plate and diffuser
The quality of the light guide plate is one of the most important factors that determine the quality of the LED panel light. The use of high-quality light guide plates can make the finished LED panel lights emit more uniformly. There will be no dark spots, water ripples, etc.
3. Lamp beads and patches
Good lamp beads not only have stable performance, good brightness and low light decay, but also have a much better color rendering index.
4. Aluminum substrate
The LED panel light has 4 aluminum substrates for light input on all sides, and 2 aluminum substrates for light input on both sides, each of which is about RMB 1.5 for 600x600.
Power supply is also the most important factor affecting the price of LED panel lights. Poor power supply directly affects the life of the LED panel light. UL power supply performance is relatively stable. There are other CE power supplies.
Simple packaging can be done for a few dollars. For example, 10 dollars is a little better than the four corners plus a box with a top cover and an outer carton.
The auxiliary materials include foam pad cotton, tape, wires, and terminals, and the cost is about 5 yuan.
8. Labor expenses
Generally 10 people produce 300 pieces a day. Calculated at 1800 yuan/person/month, 1800÷30X10=600 yuan. The labor cost is about 2 yuan/piece.
In summary, the cost of LED panel lights is between 250 yuan and 280 yuan. If better materials are used, the cost may be more than 300 yuan.

From the perspective of green lighting design, LED panel lights are environmentally friendly, low power consumption, luminous efficiency, lighting brightness and other aspects are better than grille lights, truly enjoy the lights during the day and illuminate at night. It is gradually replacing the grille lamp with T8 fluorescent lamp as the light source. The lifespan of LED panel lights is 10 times longer than that of fluorescent lamps.
