Heat dissipating system and heat dissipating method for prolonging service life of stage electric discharge lamp

Abstract

The invention relates to a heat dissipating system for prolonging the service life of a stage electric discharge lamp. The heat dissipating system comprises a heat dissipating module and a control module. The control module comprises a time reference unit; the heat dissipating module dissipates heat of the electric discharge lamp; the control module controls the heat dissipating module to open; the time reference unit times and enables the control module to open the heat dissipating module in a delayed manner, and the time reference unit starts to timing when the electric discharge lamp is switched on. A heat dissipating method comprises the following steps: when the electric discharge lamp is switched on, the time reference unit starts to time t1 second; and after timing, the heat dissipating module is opened to dissipate heat of the electric discharge lamp. When the electric discharge lamp light source is switched on, an ideal working temperature is achieved quickly and influence onthe service life of the light source is greater than that of cold and hot stress. The light source is heated more quickly by adopting a method of stopping a heat dissipating fan, so that the service life of the electric discharge lamp light source is prolonged. The time t1 is a delayed time set by those skilled in the technical field according to experience, for example, 10 seconds, and the electric discharge lamp light source is substantially at the ideal working temperature.

Description

technical field [0001] The invention relates to the field of discharge lamp lighting, in particular to a heat dissipation system and a heat dissipation method for improving the service life of stage discharge lamps. Background technique [0002] Discharge lamps have the characteristics of high light intensity and selectable radiation spectrum, and are widely used in stage lighting. However, compared with cold light sources such as LED lamps, the local temperature at the source of discharge lamps is very high, often reaching about 800°C. Therefore, if you cannot Reasonable cooling of the discharge lamp will often affect its life, and the unit price of the discharge lamp is often high, which will cause a lot of waste.

[0003] The Chinese invention patent application with the application number 201610502459.0 discloses a temperature adaptive control system and control method for LED stage lights. It detects the temperature of LED lights in real time by setting temperature sensors and sets temperature gradients. Each temperature gradient corresponds to a different fan. Mode, so as to carry out reasonable heat dissipation for LED lamps, but when this system is applied to discharge lamps, there will be great problems, because the temperature at the light source of discharge lamps is very high, and the temperature sensor cannot or is difficult to be installed at the light source, even if it can be set , using this kind of high temperature resistant temperature sensor, the cost will be very high, and the measured value is not necessarily accurate, and the reliability is not enough. especially important
