[0023] Embodiment 1

[0024] The present embodiment provides a lamp, which comprises a starting circuit and a discharge circuit;

[0025] In the present embodiment, the lamp is a xenon lamp. In the prior art, the starting circuit of the xenon lamp generally comprises a control panel, a boost coil mounted on the control panel, and a starting coil connected with the output end of the boost coil. The starting coil is wound outside the lamp tube of the xenon lamp. The working principle is as follows: the boost coil provides a high voltage of about 7200V or above for the starting coil, the high voltage on the starting coil excites the xenon gas in the lamp tube into an ionic state, and then a voltage connected with the two ends of the lamp tube is applied to the lamp tube to form a conductive path (for example, +400V and -400V are applied to the two ends of the lamp tube), so that the current passes through the lamp tube and the lamp tube emits light.

[0026] In the present embodiment, a temperature guide is arranged in the starting circuit, and a refrigerating element 1 is arranged on the temperature guide.

[0027] When the temperature guide is arranged in the starting circuit, the temperature guide is in direct contact with the lamp tube 4 of the lamp, and the refrigerating element 1 can cool the temperature guide to improve the starting rate of the lamp tube 4, and effectively reduce the temperature of the lamp tube 4 after starting to prevent the phenomenon of leakage flash caused by excessive heat due to excessive starting voltage.

[0028] In the present embodiment, as shown in Figure 1 the temperature guide is a reflecting cup 2 arranged outside the lamp tube 4, and the reflecting cup 2 is connected with the boost coil through a lead wire 6 to form the starting circuit.

[0029] The reflecting cup 2 comprises a main cup plate 2-1 surrounding the lamp tube 4 and side reflecting elements 5 arranged at both ends of the main cup plate 2-1. The side reflecting elements 5 are sleeved on the outer wall of the lamp tube 4 and are in contact with the lamp tube 4. In the present embodiment, the refrigerating element 1 is mounted on the main cup plate 2-1. In other embodiments, the refrigerating element 1 can also be mounted on the side reflecting elements 5. In the present embodiment, the reflecting cup 2 functions as the starting coil in the prior art. Since the reflecting cup has a large surface area, the refrigerating element 1 can more efficiently cool the starting circuit. The refrigerating element 1 can be a semiconductor refrigerating sheet.

[0030] The refrigeration principle of the semiconductor refrigerating sheet is based on the Peltier effect. After the semiconductor refrigerating sheet is powered on, the direct current passes through the electric couple composed of two different semiconductor materials, and heat is absorbed or released at both ends of the electric couple to achieve refrigeration through the temperature difference effect of the semiconductor material.

[0031] Wherein, Peltier effect refers to when the current through thermocouple, one of the nodes emit heat and the other node absorbs heat.

[0032] In this embodiment, the main cup plate 2-1 and the side reflection plate 5 of the reflector cup 2 are conductive bodies, and the side reflection plate 5 is electrically connected with the electrical connection end of the lamp tube.

[0033] In this embodiment, the main cup plate 2-1 surrounds the lamp tube 4, the main cup plate 2-1 is connected with the boost coil through the wire 6, and the side reflection piece 5 is arranged at both ends of the main cup plate; the side reflection piece 5, the main cup plate 2-1, the wire 6 and the boost coil are connected in series to form a starting circuit; after the boost coil is boosted, the side reflection piece 5 provides high voltage to the electrical connection end of the lamp tube, so that the xenon gas in the lamp tube ionizes and emits light under high voltage; at the same time, the main cup plate 2-1 has a reflection effect, which can reflect the light emitted by the lamp tube 4, so that the light can be emitted from the light-emitting side of the main cup plate 2-1, and the light-emitting side of the reflector cup refers to the side of the lamp tube 4 which is not surrounded by the main cup plate 2-1; at this time, the lamp tube 4 emits a large amount of light in the main cup plate 2-1, which improves the utilization rate of light.

[0034] In this embodiment, the refrigeration piece 1 installed on the main cup plate 2-1 is used to cool the main cup plate 2-1, so that the internal temperature of the main cup plate 2-1 is reduced and part of the temperature of the lamp tube 4 installed therein is taken away, thereby reducing the flashover rate of the lamp tube 4.

[0035] Wherein, the material of the side reflection piece 5 is a conductive material, for example, a non-light-transmitting metal material; the non-light-transmitting metal material can be copper or aluminum or the like; when the side reflection piece 5 receives the starting voltage, it can excite the lamp tube 4 to emit light;

[0036] In addition, the side reflection piece 5 also has a reflection effect, which can assist in reflecting the light leaked from both sides of the main cup plate to the light-emitting side of the reflector cup 2, so as to improve the utilization rate of light.

[0037] In some embodiments of the present application, in order to further reduce the flashover rate of the lamp tube 4, a refrigeration piece 1 is installed on the side reflection piece 5, the side reflection piece 5 is in contact with the lamp tube 4, the heat generated by the lamp tube 4 is transferred to the side reflection piece 5, and the refrigeration piece 1 cools the side reflection piece 5 while taking away part of the heat of the lamp tube 4, thereby reducing the flashover rate of the lamp tube 4.

[0038] In some embodiments of the present application, the refrigeration piece 1 on the side reflection piece 5 works synchronously with the refrigeration piece 1 on the main cup plate 2-1, the refrigeration piece 1 on the main cup plate 2-1 cools the main cup plate 2-1, and the refrigeration piece 1 on the side reflection piece 5 cools the side reflection piece 5; the main cup plate 2-1 is cooled while taking away part of the heat of the lamp tube 4, and the side reflection piece 5 is in contact with the lamp tube 4, the heat generated by the lamp tube 4 is transferred to the side reflection piece 5, and the refrigeration piece 1 cools the side reflection piece 5 while taking away part of the heat of the lamp tube 4.

[0039] Therefore, the main cup plate 2-1, the side reflection piece 5 and the lamp tube 4 are cooled by the two-part refrigeration piece 1, which can take away the heat of the lamp tube 4 to a greater extent and effectively reduce the flashover rate of the lamp tube 4.

[0040] The side reflection piece 5 and the main cup plate 2-1 can be integrally formed, so that the light reflection cup 2 is more solid and firm as a whole.

[0041] The main cup plate 2-1 and the side reflection piece 5 can be connected to the refrigeration piece 1 by welding or other fixed connection methods.

[0042] Embodiment 2

[0043] As shown in Figure 2 the embodiment, on the basis of the embodiment 1, the temperature guide piece is a heat conduction sheet sleeved on the lamp tube 4 and in contact with the lamp tube 4, a starting coil is wound around the lamp tube 4, the heat conduction sheet, the starting coil and the voltage boosting coil form a starting circuit, and the heat conduction sheet is externally provided with the refrigeration piece 1.

[0044] The starting circuit is powered on to generate a starting voltage, the lamp tube 4 is started by the high-voltage, and the lamp tube 4 is excited to emit light;

[0045] Since the heat conduction sheet has a large surface area and the refrigeration piece 1 is in contact with the heat conduction sheet, the high temperature in the starting circuit can be effectively taken away, so that the high temperature on the lamp tube 4 in contact with the heat conduction sheet is also taken away, thereby reducing the flashover rate of the lamp tube 4.

[0046] In the embodiment, the light reflection cup 2 can also be further provided as in the embodiment 1, and the light reflection cup 2 can have the main cup plate 2-1 and the side reflection plate 5 in the embodiment 1; the main cup plate 2-1 and the side reflection plate 5 have a reflection effect and can reflect the light emitted by the lamp tube 4, so that the light can be emitted from the light-emitting side of the main cup plate to improve the utilization rate of the light.
