Energy conserving lamp

Abstract

The invention relates to an energy-saving tube, which comprises frame, base, gas discharge bubble / tube and ballast power device. Wherein, it is characterized in that: said ballast power device is one frequency-modulation impulse power circuit formed by electric elements, which comprises low-frequency vibration control impulse generating circuit (1) whose output modulates the control end of electric high-voltage switch (2); said switch (2) directly controls the main power generating circuit (3) of bubble / tube; the main power generating circuit (3) can via the modulated frequency of low-frequency vibration control impulse generating circuit (1) output intermission impulse power to the bubble / tube to send out intermission light. The invention can make gas discharge light to send out intermission impulse light at high brightness to save energy.

Description

technical field [0001] The present invention relates to energy-saving lamps, and more specifically, it designs an energy-saving lamp that adopts a specially designed ballast power supply device and can make gas-emitting lamps emit intermittently pulsed high-brightness light. Background technique [0002] Existing gas discharge lamps are mainly composed of a housing, a lamp holder, a gas discharge bulb (lamp tube) and a ballast power supply device. The ballast power supply device is used to provide the source of the gas discharge lamp, which can ignite the gas discharge lamp and keep the current flowing through the gas discharge lamp constant within a certain power consumption. Due to the design, working principle and structure of the gas discharge lamp, a special power supply device must be equipped to work normally. In the early stage, it was equipped with an inductive coil type ballast. Later, in order to reduce copper loss and iron loss, improve luminous efficiency and re...

Problems solved by technology

[0003] However, there is such a phenomenon in real life, that is, when there are few cars and people in the middle of the night, it is unnecessary for street lights to continuously emit energy.

Especially for the street lights on the pedestrian street, the walking speed of pedestrians is very low. If the light emission of the electric light is changed to a high-brightness flash of intermittent pulses, using the persistence characteristics of the human eye (more than 24 Hz can have the feeling of continuous light), Compared with the previous continuous power supply, this intermittent pulse power supply has a difference in energy consumption, and has obvious energy-saving effects. Therefore, it is necessary to transform the current street lamps.
