(2) High-frequency energy-saving lamps with low voltage (low temperature) ignition characteristics test:
High-frequency energy-saving lamps, low-voltage and low-temperature start-up characteristics tests are carried out in the production workshop.
1. Connect the high-frequency energy-saving lamps as shown below.
2, test data record:
Put the high-frequency energy-saving lamp into the refrigerator and lower the refrigerator to -15 degrees.
The voltage was lowered to 18 OV for the ignition test. High-frequency energy-saving lamps, about 6OS after Qihui. The operating temperature of the fluorescent tube begins to enter a normally lit state. After 12OS, the best ignited state is reached.
3. Technical analysis of test results:
In -15 degrees, 18 OV, low temperature, low voltage environment. High-frequency energy-saving lamps can reliably ignite and ignite. No flicker, no jitter, no extinction and then extinguish.
(3) High-frequency energy-saving lamps, filament anti-current impact performance and life test, and fluorescent lighting life test of fluorescent tubes at normal temperature. This test mainly tests filament life and lamp life. In order to accelerate the aging destructive test, it is carried out in the laboratory of the production workshop. Auxiliary statistics of a portion of the actual application site data.
1. Connect the high-frequency energy-saving lamps as shown below.
Set the HBR-2OOO aging instrument to 1O s and 1O s to break, and 2O s is the cycle of one cycle.
The electronic ballast parameters are designed such that the filament current peak-to-peak ratio is 1:1·7, and no filament preheating. The fluorescent tube ignition ignition voltage is designed to be 2.5 times of the rated voltage.
2, test data record:
When the aging device is turned on and off for 1O72O cycles (times), a filament is blown. After the blown filament is short-circuited, the test is continued.
When the aging device is turned on and off for 2O62O cycles (times), the other filament is blown. After the newly blown filament is short-circuited, the test is continued. Fluorescent tubes are normally stable and stable under the condition of no filament current.
When the aging device reaches 2663O cycles (times), the fluorescent tube can still ignite under the condition of no filament current. However, flickering and jitter began to appear. Explain that the fluorescent tube starts to deteriorate.
When the aging device is turned on and off 2683O cycles (times), the fluorescent tube's ignition and ignition characteristics are significantly deteriorated, and the ignition is obviously difficult.
3. Technical analysis of test results:
u Technical analysis After the aging device is turned on and off for 1O72O cycles (times), a filament is blown. Although the blown filament is short-circuited, the on-off test can be continued. However, we believe that fluorescent tubes are illuminated and the ignition life is over.
According to the energy-saving lamp production industry, the fluorescent tube has been used for many years, and the calculation method for accelerated aging test. That is, once per switch, the energy-saving lamp is equivalent to igniting 1-2 hours of life. We take the intermediate value of 1.5 hours to calculate, the fluorescent tube ignition life = 1O72O times *1 · 5 hours / time = 16O8O hours, taking into account the impact of harsh factors in the actual application environment. The conservative value of 150,000 hours is scientifically based.
(This is also the scientific basis for our commitment to the user, quality assurance for one year. Because 365 days a year, 24 hours a day. One year = 365 days * 24 hours / day = 876O hours.)
u Partially ignited for more than a year, but continues to ignite the use case.

The ignition life of the trichromatic fluorescent tube depends on the ignition ignition life and the filament burnout life of the fluorescent material of the fluorescent tube.
It is known from the test data that the igniting life of the fluorescent tube fluorescent material is greater than the filament burning life. If the filament burnout life can be extended, the ignition life of the entire fluorescent tube will be greatly prolonged.
The filament burnout life is subject to both the characteristics of the filament itself and the performance of the electronic ballast. Under the premise of maintaining the characteristics of the filament itself, optimizing the technical performance of the electronic ballast and adopting the advanced technology of Qihui ignition will greatly extend the filament burnout life.
The Huabel series produced by our department is a three-color high-frequency high-power industrial and commercial energy-saving lamp. The electronic ballast is designed and produced by fuzzy adaptive control technology. The electronic ballast technology has advanced technology and prolongs the filament burnout life. The life of the entire fluorescent tube is as follows:
The market version has a lifetime of more than 100 hours;
The life of the engineering version can reach more than 150,000 hours;
The technology version can last for more than 200 hours.
Our department is increasing investment in science and technology development to further optimize the technical performance of electronic ballasts. The new technology of preheating and cold cathode ignition is adopted. The life of the filament of the fluorescent tube is increased by 1.5 to 2.0 times. The life of the entire fluorescent tube will be greatly extended.
(4) High-frequency energy-saving lamps, filament cathode sputtering (ie, work function) characteristics (limited to texts, the text is larger, the text in this document is omitted)
(5) High-frequency energy-saving lamps, rated power adaptive control characteristics test
1. Connect the high-frequency energy-saving lamps as shown below.
2, test data record:
The current value I=O·4A is based on the voltage 22OV.
When the voltage is lowered to 18 OV, the current value I>O·4A, the current I does not decrease, but tends to increase.
When the voltage is raised to 26 OV, the current value I < O · 4 A, the current I does not increase, but tends to decrease.
test results:
High-frequency energy-saving lamps when the voltage varies from 18 OV to 26 OV. The actual electric power P = V * I is stable within a reasonable range.
3. Technical analysis of test results:
u Ordinary energy-saving lamps, rated power design and debugging, with 5OHz, 22OV voltage as the standard value.
In practical applications, the grid voltage varies in the 18OV-26OV range. Ordinary energy-saving lamps, when there is no fuzzy adaptive control function, the actual electric power P = V * I, will also change accordingly. That is, when the voltage U rises, the power P increases; when the voltage U decreases, the power P decreases.
Result: Ordinary energy-saving lamps, the actual electric power P = V * I, follow the grid voltage, the range of variation is large. There are two negative effects: one is to shorten the life of the energy-saving lamp; the other is that the luminous flux changes too much, affecting the lighting effect.
u Huabel three-color high-frequency high-power industrial and commercial special energy-saving lamps (referred to as high-frequency energy-saving lamps), using advanced fuzzy adaptive control technology design and production. When the grid voltage changes, its output power has adaptive control characteristics.
Its technical mechanism:
When the grid voltage U rises, the current I does not tend to increase, but tends to decrease, and the current value decreases. High-frequency energy-saving lamps, the actual electric power P = V * I, not the linear limit increases sharply with the increase of voltage; but in the negative direction of the current I value tends to decrease, the actual electric power P = U * I, Slowly increase with a slow amount of change.
Conversely, when the grid voltage U decreases, the current I does not tend to decrease, but tends to increase, and the current value is increasing. High-frequency energy-saving lamps, the actual electric power P = V * I, not linearly follow the voltage drop and sharply decrease, but under the positive action of the current I value tends to increase, the actual electric power P = U * I, with a slow The amount of change slowly decreases.
Therefore, our company produces, Huabel three-color high-frequency high-power industrial and commercial energy-saving lamps. When the grid voltage fluctuates within the range of 18 OV to 26 OV, the actual electric power P = V * I. Under the action of fuzzy adaptive control technology, it is relatively stable within a reasonable range. High frequency energy saving lamps, in practical applications. The operation is stable, the failure rate is greatly reduced, less than 3%, and the reliability is greatly improved.
