How to produce good high-performance LED work light？
LED work lights are used more and more in automotive lighting, how to choose a high-quality and high-performance LED work lights, Guangzhou Chiming Auto light manufacturers to provide you with detailed answers.
First we from LED work lamp product internal structure analysis, a good high-performance LED work light is how to produce.
1. Lamp Bead
High-quality lamp beads are LED work lights core, the best chip in the market is using the United States Cree 3W, 5W, 10W chip, with Taiwan Epistar chip is also a good choice to ensure that the quality of the chip is very important to ensure that your manufacturer is using the authentic Cree and Epistar chip, High imitation and genuine price difference will make the product price difference of about 10%.
2. PCB board
The main performance parameters of PCB board are: heat dissipation, thermal expansion, dimensional stability. High-performance 2.0 PCB board has a great influence on the life and stability of LED work light, even with the use of a genuine chip, on the poor performance of the aluminum substrate, life will be greatly reduced. PCB board substrate composition, thickness, insulation layer thickness and process level, the performance of aluminum substrate has a great impact, the use of high purity of the substrate, the process of good circuit board manufacturers, to ensure that the aluminum substrateQuality is of great significance. Good aluminum substrate with good thermal conductivity, to ensure that the heat dissipation coefficient in more than 2.0, because of the reason for the price, the current market PCB board thickness is not enough, using 1.0mm, 1.5mm more, Can adhere to the use of 2.0mm plate has been very few, although with good thermal conductivity, heat dissipation coefficient can be close to 2.0, but the sheet is thin, the thermal expansion and dimensional stability is poor.
3. Thermal Conductive Adhesive
Similar to the computer CPU chip need to smear some of the paste material, aluminum substrate thermal conductivity of aluminum substrate heat dissipation performance is also relatively large, this aspect we are not particularly familiar with, anyway, choose the regular LED Work Light manufacturer of thermal conductivity, after comparison test, choose the best cost-effective. At present the market is used more is a low price of the white heat conductive adhesive, byWe test, the white is not as good as the gray, the price is relatively expensive, but the impact on the heat dissipation is significant, the difference between 0.15 factors.
4. LED Lamps 'Power Supply Driver
Customers want to order high-quality LED work Light, power-driven is very important, the current power-driven solutions are more similar, look at the board of Materials and thickness, the number of components on the circuit board, some can be streamlined, too much simplification is not very good, there are components of the welding process, the layout of internal lines, Good power-driven to ensure good chip life, If not will greatly shorten the life of the luminaire.
5.Lens and lamp cup
There are four kinds of LED lens materials: Silicone lens, PMMA lens, PC lens, glass lens. Silicone lenses generally small size, high temperature resistance, commonly used in the packaging of LED light emitting devices; PMMA lens commonly known as acrylic lens, not ordinary acrylic, optical grade poly methyl methacrylate, high transmittance, temperature generally 80 ℃ (thermal deformation temperature 92 ℃); PC lens adopts optical grade materialPolycarbonate, light transmittance is a little lower than the PMMA lens, heat temperature 110 ℃ (Thermal deformation temperature 135 ℃), glass lens light transmittance, high temperature, but large volume, fragile, production efficiency is low, high cost, the current application is still more difficult. So at present, led work lights and long lamps using more than the PC lens, the use of optical-grade PC materials and professional optical injection moldingMachine production, is the guarantee of PC lens quality, no bubble, no sag, no indentation, no flow, no crescent, shape accuracy rt<0.005 surface roughness ra<0.0002, is the standard of qualified PC lens.
6. Housing and bracket
High-quality LED work light housing Generally use cast aluminum, shell structure and wall thickness to achieve the strength of the design requirements, some in order to reduce the cost of materials, the need to redesign the new shape structure to ensure that the strength of the quality of the requirements, simply minus the material, will have an impact on the stability of the product. The advantages and disadvantages of the polishing and oxidation treatment process of the shell, affect the product long-term workThe state of the shell, affecting the user's satisfaction. Stand is led work light and LED light bar installation of a solid guarantee, thickness and structure must be reasonable, because of the different installation methods, LED work light general bracket using stainless steel, LED light bar using all aluminum parts. The last thing to say is led work light and LED lightBar power cord, the power cord to use pure copper core, wire diameter to and power matching, European standard silicone rubber wire is a good choice, the normal European line and some non-marking on the market is very large, some of the bad wire with a period of time, aging more severe, and some even skin partial peeling, resulting in short-circuit, So it's also a place to be aware.
In summary, we have a high-performance LED Work Light on the production of light on the understanding, we are based on their actual situation and demand, the next order to customize the products you need, any product has a high middle and low points, suitable for you is the best.
