Dismantling: take a look at OPPLE lighting LED bulb is what structure

The sample procurement is purchased by Jingdong mall. Each brand in the publicity have spared no effort, but the actual production of the product is dedicated? The answer then announced. Look at the promotional pictures:

Publicity of these two pictures, I have not read: the overall light 240 degrees, is due to the use of the 200 degree of high performance PC mask?

Packaging articles

Packaging uses a color box packaging, indicating that the product can replace 25W incandescent lamp. A detailed explanation of the product life. Life is calculated according to the average daily use of 3.5 hours, different from PHILPS's average daily use of 2.7 hours.

Like PHILPS, the box can be used for 15 years, and it is interpreted as a result of the OPPLE company's standards and laboratory test data. What is the standard of enterprise execution? Can make nothing of it

performance parameter

First look at the whole lamp photoelectric parameters:

The spectrum is as follows:

The whole lamp light:

According to the data, the basic parameters meet the requirements. Color temperature 2700K, closer to incandescent color temperature, flux will be lower than 3000K. PF value greater than 0.5, worthy of praise. From the light photo, the light angle is not 240 degrees so big. Through the spectrum, it is still the use of red phosphor and yellow green phosphor and blue chip for white light, all the color after some red.

Whole lamp dismantling

1, packing box

2, lampshade (PC material)

3, the lamp body

4, plastic screw

The lights of the PCB by two screws, screws with a plastic column independent, in order to prevent the screws and the ceramic lamp body extrusion and lead to breakage of ceramic lamp body is connected with a power supply and PCB power supply directly by PCB without the use of "part of the welding wire.

Component description

Lamp shade: adopt PC material through injection molding, through the glue and the lamp body ceramic parts combination, it is easy to unscrew. The surface of the lampshade is smooth, and the effect of the frosted surface is mainly made of light, which has a great influence on the flux loss. Through the actual test, it is found that the light transmittance of the lampshade: 0.94. In line with corporate propaganda 0.92.

Lamp body: lamp body ceramic material. Through the observation of the use of ceramic materials, it is concluded that the Al2O3 component is relatively high, and the quality is better. The heat generated by the LED directly through PCB and thermal grease conduction to the ceramic lamp body, then made of ceramic and air heat exchange.

Lamp holder: E27 lamp socket for international standard size. The use of materials for the use of iron nickel plating material (recommended the use of copper nickel plating), may be due to cost considerations.

Core components - light source components

LED: SMD 5630 device, the internal packaging of the two chips, a blue chip and a zener diode chip. According to the characteristics of the device and the chip, the initial inference LED device supplier is South Korea LG, and corporate propaganda compliance. The number of LED is only 5, the driving current is 160mA, the power supply is too large. The actual test case of light LED welding temperature: LED positive temperature of 79 degrees, LED negative temperature of 85 degrees, natural convection environment, the ambient temperature of 20 degrees.

PCB: the thickness of the 1.0mm double glass fiber board, around the LED through the PCB through the process of heat transfer to the following and the lamp body contact surface. The contact surface is coated with thermal grease, uneven coating, cooling effect.

LED test data are as follows:

Core components - power components

Publicity that the power supply has a proprietary technology.

This power is recommended where the direct connection with the lamp board, eliminating the connection line. According to the promotion of the enterprise power supply has a patent. The power supply is not used IC constant current, careful observation found that the current topology is similar to the RCC circuit, through the test found that the power conversion efficiency is not high, the use of more devices.

Overall, as a domestic brand OPPLE, product design remarkable.

Products: the use of the core components of LED, PCB and ceramic selection worthy of domestic enterprises to learn. However, the need for more stringent control of product design margin, can not exceed the use of power. Whether it is imported electronic components or domestic components, overclocking use will inevitably lead to reduced life expectancy.

Publicity: the use of its components to enhance their brand value, which is a brand of their own self-confidence. For example, PHILIPS never said that the use of other components of the home, but stressed the ability to design independently.
