Abstract

PURPOSE:To obtain a fluorescent lamp ingitor unit with a resistance ballast that can suppress the resistance ballast loss low, improve its circuit efficiency, and be suitable for energy saving by restraining the current value low. CONSTITUTION:In the figure, the left domainIof Point P indicates that the ballast loss increases as power consumption WL increases. On the contrary, the right domain II of point P indicates that the ballast loss increases even when WL decreases. This indicates that when a circuit is designed and the output of a fluorescent lamp is set to a value WLO, there are two operating points (P1, P2) of the fluorescent lamp from which the output can be obtained. In this case, when the operating point is assigned at Point P1 in the domainI, the ballast loss Q1 can be suppressed low and when the operating point is assigned at Point P2, the ballast loss Q2 is increased. For this example, the circuit current value should be preferably set belowIp in Equation (i).

Therefore, in the region (I) to the left of point P, parastros increases as WL increases. Conversely, the area to the right of point P (Il
l is the balance) loss increases even though wL decreases. This means that when designing a circuit, when trying to make the output of the 2nd fluorescent lamp a certain value wLo, there are 2 operating points of the fluorescent lamp at which that output can be obtained (point 21m, point P
2) means that it exists, and in this case, the PI of area (1)
If the K operating point is found, the parastross Q1 can be kept small, and if the operating point is found at P2, the parastross Q! becomes larger. In conventional fluorescent lamp lighting devices, the rated current when the fluorescent lamp is lit from a choke ballast is passed through the circuit, so the area (if
) had a discharge operating point. In contrast, in the fluorescent lamp device of the present invention, the discharge operating point is set in region (I).

For example, for a rated 20W fluorescent lamp, at a rated value of 50W = 1
By using an incandescent light bulb, a light output equivalent to a rated 15W can be obtained. The ballast at this time is approximately 30 inches. The circuit current at this time is 280-290 mA, which corresponds to 571 K of the ballast rated current of 500 mA, and is in the range of 9 d/m, 1 sh or less. On the other hand, in order to obtain the same 15W light output, conventionally a fluorescent lamp with a rating of 15W was used, so the ballast loss was approximately 45W.
The circuit current at this time is 360 mA, which corresponds to about 70 mA of the short circuit current of the ballast, which is outside the scope of the claims. therefore.

本実施例の場合、約1.7倍の効率改善につながる。In the case of this example, the efficiency is improved by about 1.7 times.
