Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.
[0029] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In the illustrated embodiments, directional representations, ie, up, down, left, right, front and rear, etc., are relative to explain that the structure and movement of the various components in the present application are relative. These representations are pertinent when t...

The invention discloses a lamp heat dissipation device. The lamp heat dissipation device comprises a first heat dissipation fin set, a second heat dissipation fin set, a heat pipe and a refrigerationmodule, wherein the evaporation section of the heat pipe is in heat conduction connection with the first heat dissipation fin set; the condensation section of the heat pipe is in heat conduction connection with the refrigeration end of the refrigeration module; and the heating end of the refrigeration module is in heat conduction connection with the second heat dissipation fin set. The invention further discloses a lamp. The lamp comprises a lampshade, a bulb and the lamp heat dissipation device. According to the lamp heat dissipation device and the lamp, the temperature in the lampshade of the lamp can be actively reduced through the refrigeration module, the lamp is kept in the low-temperature working environment, and therefore the service life of the lamp is prolonged.
Description
technical field [0001] The invention belongs to the technical field of heat dissipation, and in particular relates to a heat dissipation device for a lamp and a lamp with the heat dissipation device for the lamp. Background technique [0002] The light bulbs of existing lamps are usually installed in the lampshade, and the lampshade is used as a heat conduction medium to conduct heat conduction with the outside world to dissipate heat. However, the material of the lampshade generally has a very low thermal conductivity. Some high-power bulbs are seriously overheated, and usually need to be equipped with a heat sink to ensure their Work normally for a long time. Especially for car lamps and other lamps whose lampshades are airtight structures, after the lamps work for a period of time, the temperature inside the lampshade will gradually increase, making the lamps in a high temperature working state for a long time, which will affect the service life of the lamps. [0003] Th...
