Embodiment 1

[0042] Such as Figure 1-Figure 3 As shown, the water cooling device for improving the light stability of street lamps in the present invention includes a liquid level sensor 2, a controller, a solenoid valve 3, a liquid replenishment funnel 5, and a water cooling system for cooling LED chips. The water cooling system includes a liquid working medium storage box 1. The rehydration funnel 5 is located on the top of the storage tank 1, and the small end of the rehydration funnel 5 communicates with the inner cavity of the storage tank 1 through the solenoid valve 3; the liquid level sensor 2 and the solenoid valve 3 are both connected to the controller, and the liquid The level sensor 2 sends the liquid level information in the storage tank 1 to the controller, and the controller receives the information from the liquid level sensor 2 and controls the on-off state of the solenoid valve 3 .

[0043] The replenishment funnel 5 is used for storing rainwater. The liquid level senso...

Embodiment 2

[0046] The present invention is based on embodiment 1, and the present invention is further described.

[0047] Such as Figure 1-Figure 3 As shown, the water cooling device for improving the light stability of street lamps in the present invention is provided with a filter screen 6 on the large end surface of the liquid replenishment funnel 5 , and the filter screen 6 covers the large end surface of the liquid replenishment funnel 5 .

[0048] The filter screen 6 filters out impurities in the rainwater, while preventing objects such as leaves from entering the rehydration funnel 5 .

Embodiment 3

[0050] The present invention is based on embodiment 2, and the present invention is further described.

[0051] Such as Figure 1-Figure 3 As shown, the water cooling device for improving the light stability of street lamps in the present invention also includes a driving device, and a mounting ring 7 coaxial with the liquid replenishing funnel 5 is arranged on the large end surface of the liquid replenishing funnel 5, and the filter screen 6 is arranged on the mounting ring 7 , and one end of the mounting ring 7 is hinged to one side of the large end face of the rehydration funnel 5;

[0052] The driving device is connected to one end of the mounting ring 7 close to the hinge axis, and drives the mounting ring 7 to rotate around the hinge axis, so that the end of the mounting ring 7 away from the hinge axis can contact the end of the rehydration funnel 5 away from the hinge axis; And the motor of the driving device is connected with the controller, and the controller control...

Abstract

The invention discloses a water cooling device for improving street lamp lamplight stability. The device comprises a liquid level sensor, a controller, an electromagnetic valve, a liquid replenishment funnel and a storage box. The liquid replenishment funnel is located at the top of the storage box, and the small end of the liquid replenishment funnel communicates with an inner cavity of the storage box through the electromagnetic valve; and the liquid level sensor and the electromagnetic valve are both connected with the controller, and the controller receives information from the liquid level sensor and controls the on-off state of the electromagnetic valve. When a working medium in the storage box is reduced, the controller enables the electromagnetic valve to be in an on state so as to enable rainwater stored in the liquid replenishment funnel to enter the storage box, and the evaporated working medium of the storage box is replenished accordingly; therefore the working medium does not need to be manually added, and the worker labor intensity is relieved; and when the working medium in the storage box is reduced, the controller can automatically conduct self-replenishment through related devices, and the situations that when the working medium in the water cooling system is reduced, lamplight stability is lowered, and lamplight flickers are avoided.

Description

technical field [0001] The invention relates to a cooling device, in particular to a water cooling device for improving the light stability of a street lamp. Background technique [0002] Street lamps are an important part of urban lighting. Traditional street lamps often use high-pressure sodium lamps. The overall low light efficiency of high-pressure sodium lamps has caused a huge waste of energy. Street lamps are of great significance to urban lighting energy saving. [0003] LED street lamps are semiconductor lighting lamps. LED chips with light-emitting diodes are used as light sources. Because they are solid-state cold light sources, they have the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. The difference between LED street lamps and conventional high-pressure sodium street lamps is that the light source of high-power LED street lamps is powered by low-voltage DC, and is a high-efficiency w...
