Technological innovation and economic development are changing people's lives unknowingly. The protagonist I want to introduce is one of them: LED panel light.
The LED panel light uses SMD patch as the light source, plus the light guide plate and/or diffuser plate, so that the thin design of the LED panel light can not only provide illumination, but also add artistic beauty.
At present, LED panel lights are mainly used in office lighting, classroom lighting, hospital lighting, and hotel lighting.
When LED lighting was just emerging, T5 and T8 grille lights dominated by traditional fluorescent light sources were the main competitors of LED panel lights. As the price of LED panel lights is close to that of traditional grille lights, the market competitiveness of LED panel lights is fully reflected. LED panel lights are becoming more and more popular as a replacement for traditional grille lamps and whiteboard lamps.
First, the classification of LED panel lights
By shape:
LED panel lights can be divided into square, rectangle, circle, outer square and inner circle, etc. (It's usually the same shape as the traditional grille light, or is it a replacement?)
Size by specification:
300mmx300mm, 300mmx600mm, 300mmx1200mm, 600mmx600mm. (These are the fundamental moduli of space.)
Direct-type flat panel light: As the name suggests, the light-emitting direction of the light source is the same as the light-emitting direction of the whole light.
Side-emitting panel light: uses light guide technology to direct side light to the front
Applications: hotels, conference rooms, offices, corridors, commercial use and home bedrooms, etc.
Installation method: embedded, hanging, ceiling
The main disadvantages of side-emitting LED panel lights are:
Forward, less energy efficient. It is not difficult to imagine that if the LEDs are placed around and guided down through the light guide plate, the export efficiency is lower than that of the direct type, resulting in lower overall energy efficiency.
Second, the quality requirements of the light guide plate are relatively high. If the design is not good, it will appear bright in the middle, dark on both sides, or bright edges on the incoming light side, or inconsistent brightness at different angles, etc., which will affect the lighting quality. (If a worker wants to do a good job, he must first sharpen his tools, make good products, and have materials in place. What did the couplet from Tongrentang say?)
Third, the reliability performance is relatively poor. Since the light guide plate, reflective ink and reflective film in the side-emitting flat panel lamp are always at a relatively high temperature, it is easy to age and turn yellow, resulting in a reduction in the light output rate and a greatly reduced lamp life.
Compared with side-emitting LED panel lights, direct-emitting LED panel lights have the following advantages:
Forward and energy efficient. The light emitted by the LED is directly irradiated by the diffuser plate, which improves the energy efficiency of the lighting system. (The advantage of going straight is high efficiency.)
Second, the cost is low. The cost of the light guide plate is omitted, the cost of the lamp is reduced, the internal space is larger, and the design is more flexible.
Third, the lamps are light. The mass of the luminaire is reduced because the light guide plate is omitted.
Fourth, high reliability. We know that in the design of lamps, the performance of each component and the materials used will determine the performance of the lamp product, the increase of components and the decrease of reliability. So if you use a better quality diffuser plate (note that this is a premise), the lamp can guarantee a longer life.
Is there really a product that has only advantages and no disadvantages? Then everyone uses the straight-down type, but what side-entry type do you use? As the saying goes: sugar cane is not sweet at both ends.
The main disadvantage of the backlight LED panel light is that it cannot be made too thin. the reason is:
There must be a certain distance between the front, LED light source and the diffuser, otherwise the light-emitting point will be visually seen. (So going straight is often unacceptable.) This will inevitably lead to an increase in the thickness of the lamp and the cost of the lamp housing. (The future that is as thin as a cicada's wings cannot afford the cost of dismantling.) And the increase in thickness increases the transmission path of light, which reduces the energy efficiency of lamps and lanterns, which needs to be overcome.
Second, since the lamp beads are fixed on the back panel, if the back panel uses a whole piece of aluminum substrate, the cost will be very high. If a strip-shaped aluminum substrate is used, fixing and positioning are another problem.
2. Prospects for LED panel lights
Finally, let's look at the future in one sentence.
The first, the market acceptance is gradually improved, and the market sales volume is gradually expanded. LED panel lights are sought after by the market because of their thinness. LED panel light should take advantage of the characteristics and advantages of LED itself, under the premise of meeting practical needs and maximizing the energy efficiency of the light source, the lamps should be thinned and personalized appearance design, so as to be able to be used in the future general office lighting and commercial lighting market. will occupy a place.
Second, various customized LED panel lamps will appear. With the advancement of LED driving technology and the development of intelligent systems, the development of LED panel lights will also be diversified. For example, a series of new products such as dimmable LED panel lights and color-changing LED panel lights will gradually be sought after in the market.
Third, the problem of difficult maintenance will be solved. Different from the traditional fluorescent lamp grille lights, if the light source of LED lamps is broken, the whole lamp must be replaced, and the maintenance cost is relatively high. This is a common problem faced by all LED lamps. I believe that with the advancement of technology, there will be corresponding solutions.
3. Cost: The economic benefits brought by the product cannot ignore the cost.
Direct type panel light: There is no comparison in the cost of aluminum materials. The factor affecting the direct type cost is the number of light sources. According to the actual comparison, the cost of the direct type product of the same size is slightly lower than that of the side-emitting panel lamp.
Side-emitting flat panel light: The light guide plate directly leads to an increase in cost.
