Problems solved by technology

[0002] The current indoor lighting lamps, especially indoor par lights and downlights, often shorten the service life of the lighting lamps due to high temperature during actual use, or even if the lighting lamps are not burned out, the output power of the power supply will be too high. If the bulb is too large or the temperature is too high, it will cause the bulb to flicker, which will have a great impact on the use effect; when it is more serious, it may also bring serious safety hazards

Embodiment 1

[0029] Such as Figure 1 to Figure 5As shown, this example provides a power supply control device for indoor lighting, including: an input rectification module 1, a main control module 2 and an output rectification module 3, and the input rectification module 1 and the output rectification module 3 are respectively connected to the main control module 2 The input rectification module 1 is used to filter and rectify the input power, the main control module 2 is used to detect and control the working state of the power supply of the indoor lighting lamp, and the output rectification module 3 is used to realize the Filtering, rectification and voltage regulation of the output power supply, the main control module 2 detects the working environment temperature of the indoor lighting lamp in real time through the temperature detection unit 201, and reduces the output current of the power supply when the working environment temperature is higher than the temperature preset value.

Embodiment 2

[0033] Such as figure 1 , figure 2 and Figure 6 As shown, on the basis of Embodiment 1, this example also includes a sampling feedback circuit 4 and a heat dissipation device, the sampling feedback circuit 4 is used to detect the working state of the heat dissipation device, and feed back the working state of the heat dissipation device to the main control module 2 to control the output power of the power supply.

[0034] The heat dissipation device is installed in the lamp of the indoor lighting lamp, and is used to dissipate heat for the working environment of the indoor lighting lamp. The heat dissipation device can be a fan, or a heat dissipation device such as a heat sink; the sampling feedback circuit 4 detects in real time The working status of the heat dissipation device, when the heat dissipation device fails, the fault information will be fed back to the main control module 2 in time, and the main control module 2 will derate the indoor lighting after receiving t...

Embodiment 3

[0043] On the basis of Embodiment 1 or Embodiment 2, the temperature preset value in this example is 65°C. When the working environment does not exceed 65°C, the working state of the indoor lighting is the most stable. It has been proved by tests that especially for indoor lighting with small and medium power below 60W, such as the lying lamp below 60W, the working state of the indoor lighting does not exceed 65°C. High work safety factor and long service life. Of course, the temperature preset value can be adjusted according to different application environments. For indoor lighting lamps with low and medium power below 60W, the temperature preset value in this example is set to 65°C, which has the best effect.

[0044] A further improvement of this example is that the indoor lighting lamp is a par lamp with a power below 60W. This example is not limited to party lights below 60W, but it is preferably low-to-medium-power indoor lighting below 60W. The temperature of such sma...

Abstract

The invention provides a power source control device for an indoor illuminating lamp. The power source control device comprises an input rectifying module, a main control module and an output rectifying module. The input rectifying module and the output rectifying module are respectively connected with the main control module, and the input rectifying module is used for filtering and rectifying an input power source. The main control module is used for detecting and controlling the working state of a power source of the indoor illuminating lamp. The output rectifying module is used for filtering and rectifying an output power source and adjusting the voltage of the output power source, and the main control module is used for detecting the working environment temperature of the indoor illuminating lamp in real time through a temperature detecting unit. When the working environment temperature is higher than a preset temperature value, output current of the power source is reduced. When the working environment temperature is higher than the preset temperature value, derating control over the power source of the indoor illuminating lamp is automatically performed, meanwhile, the service life, safety performance and normal working of the indoor illuminating lamp are guaranteed, and the defect that the indoor illuminating lamp is burned out due to over temperature or flickers is avoided.

Description

technical field [0001] The invention relates to a power control device, in particular to a power control device for an indoor illuminating lamp. Background technique [0002] The current indoor lighting lamps, especially indoor par lights and downlights, often shorten the service life of the lighting lamps due to high temperature during actual use, or even if the lighting lamps are not burned out, the output power of the power supply will be too high. If the bulb is too large or the temperature is too high, it will cause the bulb to flicker, which will have a great impact on the use effect; when it is more serious, it may also bring serious safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a power control device for indoor lighting that can automatically derate the output when the temperature exceeds the set value. [0004] In this regard, the present invention provides a power supply control devic...
