High quality square led tube batten light selection
1. Profile and structure
Now there are basically two types of high quality square led tube batten light profiles on the market: full plastic, half plastic and half aluminum tube,
1. All plastic High quality square led tube batten light:
The early LED fluorescent lamps used all-plastic High quality square led tube batten light, because the main use of the isolated power supply. To avoid electric shock problems. So I prefer to use all-plastic High quality square led tube batten light.
Inside is a medium 5 straw hat tube LED. The biggest problem of this kind of fluorescent lamp is the heat dissipation problem. Since all the heat is sealed in the tube, it cannot be dissipated at all, and the light decay is very serious. In addition, the life of the straw hat tube is very short, and it will be broken in less than 2000 hours.
2. Half-plastic half-aluminum tube: The LED fluorescent lamps sold on the market are basically this kind of half PC and half aluminum alloy. The half that needs light transmission is plastic, and the half that does not need light transmission and needs heat dissipation is Made of aluminum alloy.
Of course, the power supply is placed inside the aluminum tube, so the calorific value of the ED plus the calorific value of the power supply is quite large, because the power of this kind of lamp is usually around 2. If the power is bigger, half an aluminum tube can't solve its heat dissipation problem.
Therefore, another kind of aluminum tube structure is proposed: the fan-shaped aluminum tube. The fan-shaped aluminum tube adopts a fan-shaped heat dissipation structure, which greatly increases the radiator area. It puts the power supply out of the tube, so that the half of the aluminum shell can be completely made into a heat sink.
Compared with the semi-circular aluminum tube, its heat dissipation area is increased by at least 3 times.
2. High quality square led tube batten light chip
There is basically nothing to say about this. Generally speaking, the quality of first-tier brands such as CREE, Osra, Hewlett-Packard (HP), Nichia), Toyoda Gosei Lunileds is definitely better than that of second-tier or Taiwanese brands.
Currently used in fluorescent lamps are 3528, 3020, 3014 and other specifications, these specifications are mainly High quality square led tube batten light size, chip heat dissipation is not the same. Chips of the same brand are packaged by different manufacturers and their quality is also different.
High quality square led tube batten light Key technology
Light performance (light distribution) of High quality square led tube batten light
The optical performance of LED lamps mainly involves the performance requirements of luminosity, spectrum and chromaticity.
According to the industry standard "Semiconductor Light Emitting Diode Test Method", there are mainly luminous peak wavelength, spectral radiation bandwidth, axial luminous intensity angle, luminous flux, radiant flux, luminous efficiency, chromaticity coordinates, correlated color temperature, color purity and dominant wavelength, display parameters such as color index. High quality square led tube batten light commonly used white LED, color temperature, color rendering index and illuminance are particularly important, it is an important indicator of lighting atmosphere and effect, and color purity and dominant wavelength are generally not required.
Thermal performance (structure) of High quality square led tube batten light
The luminous efficiency and power supply of High quality square led tube batten light for lighting is one of the keys to the LED industry. At the same time, the issues of PN junction temperature and housing heat dissipation of High quality square led tube batten light are particularly important. The greater the difference between the PN junction temperature and the lamp body temperature, the greater the thermal resistance, and then the light energy is converted into heat energy and consumed in vain, and the LED is damaged in severe cases.
A good structural engineer should not only consider the structure of the lamp and the thermal resistance of the High quality square led tube batten light, but also consider whether the shape of the lamp is reasonable, fashionable and novel, and of course reliability, maintainability and practicality. It is necessary to think from the designer's point of view, but also to consider the product from the user's point of view.
Electrical properties of High quality square led tube batten light (electronics)
If a High quality square led tube batten light is compared to a girl, then the light distribution is her connotation, the structure is her appearance, and the electron is her heart. It is always those beautiful and fashionable beauties who attract people's attention, and the same is true for High quality square led tube batten light.
A person has no life without a heart. A high quality square led tube batten light cannot be a power source without electronics. A good driving power source can also determine the life of a product.
The electronic standards and parameters are often much more complicated than the structure, and the RD energy investment in the early stage is also relatively large. The current technological trends and updates are changing with each passing day, and engineers have to spend a lot of energy to learn, absorb, decompose, and apply new technologies.
The whole process of early planning, mid-term implementation, and later molding of electronic design needs to form documents and data, which is also the most tedious thing in design. For example: a preliminary plan in the design of a power supply, product introduction, standard specification basis, safety specification basis, expected electrical performance, process requirements, raw material evaluation, test methods, etc. must be formed into system documents.
