Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The utility model provides a lamp with automatic power control, which is shown in fig. 1 to 3 and comprises a shell 10, a focusing lens 20 and an end cover 30; one end of the shell 10 is in threaded connection with the focusing lens 20, and the other end of the shell 10 is in threaded connection with the end cover 30; a temperature sensor (not shown), a controller 40 and a light emitting element 50 are arranged in the housing 10, the temperature sensor is electrically connected with the controller 40, the controller 40 is electrically connected with the light emitting element 50, and when the temperature measured by the temperature sensor is higher than a preset value, the controller 40 reduces the power of the light emitting element 50.

For example, assuming that the preset value is 50 ℃, when the temperature detected by the temperature sensor is lower than 50 ℃, the normal operating power of the lighting element 50 is maintained, but when the temperature detected by the temperature sensor is higher than 50 ℃, the controller 40 reduces the operating power of the lighting element 50, so as to reduce the heat generated by the lamp, thereby preventing the lamp from being damaged due to overheating inside the lamp.

As shown in fig. 1 and 3, a heat sink 61 and a heat exhaust fan 62 are provided in the housing 10, the heat sink 61 abuts against the housing 10 and the light emitting element 50, and the heat exhaust fan 62 is disposed opposite to a surface of the heat sink 61 facing away from the light emitting element 50.

When the lamp is applied, the heat sink 61 can rapidly acquire heat generated by the light emitting element 50 and send the heat to the housing 10, so that the heat dissipation efficiency is improved, and the heat exhausting fan 62 can form turbulent flow inside the housing 10 to avoid the problem of local overheating inside the housing 10, so that the problem of too low heat dissipation efficiency of the existing lamp can be solved.

As shown in fig. 1 and 3, the heat exhausting fan 62 is plural, the plural heat exhausting fans 62 are arranged in an axially separated arrangement along the housing 10, the controller 40 is arranged adjacent to the heat exhausting fans 62, and a space between the adjacent heat exhausting fans 62 is used for placing internal components of the lamp.

The controller 40 is used for regulating and controlling the working state of the lamp, namely, the heat dissipation effect is improved by increasing the number of the heat dissipation fans 62, and the space between the adjacent heat dissipation fans 62 is reasonably utilized, so that the heat dissipation uniformity and the efficiency of each part are ensured, and important help is provided for maintaining the normal work of the controller 40.

Moreover, the controller 40 of this embodiment includes a plurality of control boards 41, and the plurality of control boards 41 are respectively disposed between each adjacent heat exhausting fan 62, so that the heat exhausting fan 62 can perform heat dissipation processing on each control board 41, thereby providing a guarantee for stable heat dissipation of the lamp.

As shown in fig. 1 and 3, a plurality of partition plates 71 are arranged in the housing 10, the plurality of partition plates 71 are arranged in an axial direction of the lamp, a plurality of fixing posts 72 are connected between adjacent partition plates 71, the plurality of fixing posts 72 are arranged in a peripheral direction of the partition plates 71, and internal components of the lamp are arranged on the plurality of partition plates 71.

After the partition 71 is additionally arranged, the partition 71 can divide the interior of the lamp into a plurality of spaces, so that devices in the lamp can be separately placed, for example, the heat sink 61, the heat exhausting fan 62, the light emitting element 50, the controller 40 and the like can be placed, the phenomenon of local overheating caused by over concentration of the devices can be avoided, and heat dissipation in the lamp can be facilitated.
