LED Panel light product description:

Since the development of LEDs, chip efficiency has continued to increase and prices have continued to decline. LED flat lights are divided into two categories, with lower cost, commonly known as direct lighting. This type of assembly and production is similar to the practice of advertising boxes, and the higher cost is the side emitting light guide type. , This article introduces the specifications and details of our company's panel lights in detail.

1-1 Direct type LED flat light PD-PL 32W LED LED introduction

Product section view


1. Emphasize high luminous flux.

2. The design and structure are simple, and the assembly cost is low.

3. The thickness is about 30mm and the weight is about 1.8 kg


1. With more LEDs, the probability of LED failure is high.

2. Long-term use of LED light decay is obvious.

1-2 Side emitting LED panel light PD-PL36W

Product section view



1. Emphasize high illuminance and soft light.

2. The life of the LED chip is more than 50,000 hours. (Note: The life of the LED is up to 5 years when used daily)

3. The thickness is about 10mm and the weight is about 3.5 kg.


1. The design structure is more complicated and the material cost is high

2. The center of the LED will gradually become darker when used for more than 50,000 hours.

2-1Minor specifications of direct light and side light panel lights:

1. The LED grade and quantity are different, under the condition of 2x2 feet (60x60cm):

A. The selection range of direct light-emitting LEDs is SMD2835 as the mainstream, and the number of LEDs used is

From 48pcs, 64pcs, 108pcs, 144pcs, 192pcs... etc., the brightness of series and parallel is different to match the power supply.

B. Side-emitting LED selection restrictions SMD5630, SMD2835 are the mainstream. The number of LEDs used,

Only 120 and 192, the brightness of series and parallel is different to match the power supply.

The appearance of SMD 5630 LED on the left, the appearance of SMD2835 on the right

Choose different LED power levels, such as 32W~36W, to distinguish between high voltage and low current and low voltage and constant current.


A. Direct 48 LEDs use DC260~290V/100mA

B. Direct 64 LEDs use DC30~42V/890mA

C. Side emitting 192LED uses DC28~40V/900mA

D. Side emitting 120LED uses DC28~40V/900mA

Note: Each LED has different voltage characteristics, series and parallel connections, different brands, and different life spans.

2-3 LED Brand & Life OSRMA / Lumileds / EPISTAR / SANAN :

Brand models of LEDs and LED panel lights produce different effects, different heat dissipation, and different lifespans.

LED distinguishes voltage, current, brightness, temperature curve, LM-80 curve... etc.

LED specifications are different for each brand, and the difference in the cost and warranty of the extended calculation cannot be fabricated!!

Note 1: LM-79 description:

Test method for luminous flux of LED light source.

LED light source bulbs and lamps, including lighting content:

1. The luminous service rate of the light source at different temperatures.

2.The color maintenance rate of the light source at different temperatures.

Note 2: LM-80 description:

Test methods for LED products, including test content:

1. Electrical parameters (power, voltage, current, power factor).

2.Color parameters.

3. Luminous flux and light effect.

4. Light intensity distribution.

5. Chromaticity unevenness.

2-4 The board on which the LED is placed is called LED PCB. The following two types are introduced

A. FR-4, called fiberglass board, is coated with LED components after copper plating.

B. Aluminum substrate: A thermally conductive insulating layer is sandwiched on the aluminum substrate and the LED components are coated after copper.


Note 1: The heat dissipation composition of the aluminum substrate and the thermal insulation layer has a better heat dissipation effect than FR-4.

2: The thickness range of the LED panel light substrate is 0.8~1.6mm.

2-5Structural heat dissipation mode:

Direct light:

The LED substrate is attached to the backplane structure for heat dissipation, and the backplane is made of iron or aluminum.


Side light:

The LED substrate is attached to the structure on both sides of the frame for heat dissipation, and the frame is made of aluminum alloy.
