Description

Technical Field

[0001] The utility model relates to the technical field of gas discharge lamps, in particular to a cold end construction device for a gas discharge lamp tube. Background Art

[0002] Gas discharge lamps are an important type of artificial light source. Generally, they are significantly affected by environmental conditions during operation, especially temperature, which affects the internal working pressure and thus their working efficiency. For example, low-pressure mercury lamps have a narrow operating temperature range. The mercury vapor pressure of mercury lamps is closely related to the wall temperature of the lamp tube. It is often difficult to operate in the best state by simply relying on natural heat dissipation. The dynamic range of the test is also extremely narrow. Effective control is required for more accurate measurement of luminous characteristics, which is also convenient for clarifying the working requirements of the light source and improving its luminous efficiency and total radiation flux. At present, some manufacturers place the light source in a cold air flow, or place the outer sleeve in a water flow for testing. These are quite different from the actual wall temperature, making it difficult to clarify the actual working conditions. When the environmental conditions change, the light efficiency will be seriously affected.

[0003] Therefore, there is an urgent need for a gas discharge lamp cold end construction device that can improve the light efficiency. Utility Model Content

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0033] Example 1

[0034] refer to Figure 1-3 The specific embodiment of the utility model provides a gas discharge lamp cold end construction device, including:

[0035] Light source 3;

[0036] A temperature control zone 3-3, wherein the temperature control zone 3-3 is arranged on the light source 3;

[0037] The temperature control unit is installed in the temperature control zone 3-3.

[0038] At present, some manufacturers place the light source in a cold air flow, or place the outer sleeve in a water flow for testing, which is quite different from the actual wall temperature, making it difficult to clearly determine the actual working conditions. When the environmental conditions change, the light efficiency will be seriously affected. In this application, a temperature control zone 3-3 is set on the light source 3. In this area, the temperature control unit can make the light source 3 work within a stable temperature range, thereby improving the power density and service life of the light source 3 to a certain extent. On the whole, this application improves the light efficiency of the light source 3 by adjusting the working temperature of the light source 3.

[0039] To further optimize the solution, the temperature control unit includes:

[0040] A fluid temperature control ring 7, which is sleeved on the light source 3 and located in the temperature control zone 3-3;

[0041] The temperature control component is connected with the fluid temperature control ring 7.

[0042] The main function of the fluid temperature control ring 7 is to absorb the temperature within the temperature control zone 3-3, thereby adjusting the overall working temperature of the light source 3; the main function of the temperature control component is to transport the fluid medium into the fluid temperature control ring 7. The fluid temperature control ring 7 absorbs the heat of the light source 3 or transfers heat to the light source 3 and then transports the heat to the temperature control component through the fluid medium. The temperature is then adjusted (cooled or heated) by the temperature control component and then transported back to the fluid temperature control ring 7, so that the fluid temperature control ring 7 continues to adjust the temperature of the light source 3, so that the light source 3 can continue to emit light efficiently in a stable ambient temperature.

[0043] To further optimize the solution, the temperature control components include:

[0044] The temperature control box 6, the inlet and outlet of the fluid temperature control ring 7 are respectively connected to the temperature control box 6;

[0045] The circulating pump 4 is connected between the temperature control box 6 and the fluid temperature control ring 7 .

[0046] The temperature control box 6 is installed with electric heating wires and a conventional water cooling box (the cooling method in the high-efficiency water cooling box of CN201510677967.8 can be adopted); the circulating pump 4 drives the fluid flow in the temperature control box 6 and the fluid temperature control ring 7; when the temperature of the light source 3 is higher than the set working temperature, the heat is transferred to the fluid therein through the fluid temperature control ring 7, and then the circulating pump 4 drives the heated fluid to be transported to the temperature control box 6 for cooling, and then transported to the fluid temperature control ring 7 to continuously cool the light source 3; when the temperature of the light source 3 is lower than the set working temperature, the temperature control box 6 heats the fluid, and the circulating pump 4 drives the heated fluid to the fluid temperature control ring 7, and the temperature of the fluid is continuously transferred to the light source 3 to continuously keep the light source 3 warm; through the above process, the temperature of the light source 3 is continuously adjusted to ensure the stable light effect of the light source 3 and the ability to emit light within a wide temperature range.

[0047] Further optimization plans also include:

[0048] The electric control box 1 is electrically connected to the circulation pump 4 and the temperature control box 6.

[0049] A PLC controller is installed in the electrical control box 1, and is also electrically connected to a temperature sensor (not shown in the figure). The temperature of the fluid in the fluid temperature control ring 7 is sensed by the temperature sensor, and the temperature signal is transmitted to the electrical control box 1. A cooling or heating signal is sent to the temperature control box 6 according to the fluid temperature to cool or heat the fluid, thereby automatically completing the temperature control of the light source 3.

[0050] Further optimization plans also include:

[0051] The heat-conducting adhesive 8 is sleeved on the outside of the light source 3 and is contacted with the fluid temperature control ring 7 .

[0052] The temperature state of the light source 3 can be effectively transferred to the fluid in the fluid temperature control ring 7 through the thermal conductive adhesive 8, and the temperature signal of the fluid is obtained through the electric control box 1, and the temperature control box 6 is controlled to cool or heat the fluid.

[0053] To further optimize the solution, the fluid temperature control ring 7 is provided with a fluid temperature control ring inlet 7-1 and a fluid temperature control ring outlet 7-2. In order to speed up the fluid circulation speed, multiple groups of fluid temperature control ring inlets 7-1 and fluid temperature control ring outlets 7-2 can be provided on the fluid temperature control ring 7.

[0054] To further optimize the solution, the fluid can be a gas or an insulating liquid, and its resistivity should be greater than a specific value a, a=U / (0.03*d), where U is the positive and negative electrode voltage, 0.03 is the leakage protection current of 30mA, and d is the distance between the positive and negative electrodes.

[0055] According to a further optimized solution, the fluid temperature control ring 7 is sleeved on part or the whole of the light source 3 .

[0056] According to different illumination requirements of the light source 3, a fluid temperature control ring 7 with different light transmittance is selected.

[0057] According to a further optimization scheme, the light source 3 is a fluorescent lamp, a high pressure mercury lamp, a sodium lamp or a metal halide lamp.

[0058] According to a further optimized solution, the light source 3 includes a lamp tube connector 3-1 and a lamp tube 3-2, and the temperature control zone 3-3 is arranged on the lamp tube 3-2.

[0059] The electric control box 1, the circulation pump 4, the temperature control box 6 and the lamp tube joint 3-1 are electrically connected through the wire 2; the circulation pump 4, the temperature control box 6, the fluid temperature control ring inlet 7-1 and the fluid temperature control ring outlet 7-2 are connected through the fluid pipeline 5.

[0063] The cooling fan 3-5 is installed on the light source 3 and is arranged corresponding to the fin-type cooling ring 3-4.

[0064] After the fin-type heat dissipation ring 3-4 absorbs the temperature of the light source 3, the heat dissipation fan 3-5 dissipates heat and cools the fin-type heat dissipation ring 3-4.
