Nowadays, the price of raw materials has risen and the supply price of each product has also gone up. For counterparts engaged in importing and exporting luminaires, the question of how to source more cost-effective luminaires has become a key issue. You can choose the right supplier according to your needs. The materials, parameters and certificates of the luminaire products are all factors that need to be considered. Luminaire accessories include electronic parts, structural parts and packaging. We will look at the basis of luminaire accessories today and explain how to choose the LED luminaire that meets your needs.
1.Choose an SMD chip or a COB chip?
First of all, the lamp beads are divided into ordinary SMD and the new COB, which need to be encapsulated on the substrate.
*The material of substrates, is mainly aluminum. The heat dissipation performance and cost performance of aluminum substrate are relatively very high.
SMD refers to Surface Mounted Devices, which is a type of SMT (Surface Mount Technology) component. COB refers to Chip-On-Board, which is a small power chip packaged directly onto an aluminium substrate for fast heat dissipation, with a small chip area, high heat dissipation efficiency and small drive current. Thus, COB has low thermal resistance and high thermal conductivity and high heat dissipation. Compared to ordinary SMD low-power light sources, the features are: higher brightness, lower thermal resistance (6°C/W), lower light decay, higher light output, perfect light spot and long life.
If you have high requirements for colour rendering index, or you are purchasing photographic equipment related products, then COB light sources will be more suitable for you.
2. About the driver
The driver converts the constant current voltage into the DC DC voltage required by the lamp beads.
Structure: According to the structure of the driver, it’s mainly divided into 4 kinds: isolated, non-isolated, DOB and linear. Among them, the non-isolated driver is smaller and cheaper; the linear driver is very popular in the European market at present, due to its low cost and easy to pass EMC certification.
Operation range: According to the operating range of the driver, it can be divided into wide voltage drive (85V-265V), narrow voltage drive (175V-265V), single voltage drive (220V) and low-voltage drive (3.7V, 5V, 12V, etc.), which is a wider operating range of voltage drive, can achieve basically the same power. But in fact, the cost of consumption is higher.
3. About structural components.
The structural parts mainly include the housing, frame, reflector, lampshade and other accessories.
Housing: metal or plastic. the price is generally related to the weight. In the case of high power, aluminium is generally chosen as the material. With a reasonable weight, it is necessary to enhance the heat dissipation area as much as possible. In the case of low power, plastic is generally chosen, as it cannot assume the heat dissipation function and can only be dissipated with the help of the lamp plate (aluminium substrate).
Frame (cover): metal or plastic. At present, in order to reduce costs, the frame is gradually disappearing and is replaced by glue.
Reflector: available in white PC, white nano PC and silver plating.
Lampshades: plastic or glass. Glass has better light transmission, divided into frosted glass and ordinary glass, frosted glass light effect super hundred, natural cost also elevated.
Other accessories are wires, screws, etc. If the waterproof function is required for outdoor use, silicone rings should be added.
4. About packaging.
The packaging includes the manual, power label, inner film bag, colour box and outer box.
The colour box accounts for the largest proportion of the cost, and can be made of a thin single copper paper of 350g, and a thicker single and double corrugated, with the style of aeroplane box, etc. The beauty and complexity of the pattern also determine the cost of the colour box. The requirements for instructions and boxes vary according to the region where the luminaire is exported. We will introduce you to the specific differences in other articles.
You can simply analyse the price/performance ratio of LED luminaires in terms of electronic components, structural components and packaging to choose the product category you need. However, there are many factors that influence the price of LED luminaires. Sometimes you cannot rely on the surface material alone to judge the price, and even the lifespan may be different for the same parameters. HomeBest provides you with high quality, cost-effective products and services, so you can shop the HomeBest range of LED luminaires with confidence.
