The purpose of the utility model is realized by the following technical scheme: the utility model provides a take radiator fan's work lamp, includes the support and connects the lamp body on the support, and the lamp body includes casing and the light-emitting component who sets up in the casing, still is provided with in the casing to be used for carrying out radiating radiator fan to light-emitting component, be provided with on the casing air intake and with the air exit.

In the utility model, the light-emitting component is radiated by the radiating fan. Under the action of the heat dissipation fan, air flow is formed in the shell, external cold air enters the shell from the air inlet, and the cold air cools the light emitting assembly and then is discharged from the air outlet. The light-emitting component is cooled and radiated by the cooling fan in an air cooling mode, and compared with the traditional mode of radiating by the radiating fins, the radiating efficiency is greatly improved, and the radiating effect is good.

Preferably, the light emitting component is an LED light emitting component.

Preferably, the bracket is "U" shaped.

Preferably, the support comprises a base, supporting arms are arranged on two sides of the base, connecting shafts are arranged on the supporting arms, connecting holes matched with the connecting shafts are respectively formed in two sides of the shell, and the connecting shafts are rotatably connected in the connecting holes. The lamp body is rotatably connected with the support, so that the lamp body can rotate on the support, and the lighting direction of the lamp body can be adjusted.

Preferably, tooth sockets are arranged on the inner wall of the connecting hole, and the tooth sockets are arranged on the inner wall of the connecting hole in an annular array mode; the front end of the connecting shaft is provided with a center block, elastic arms are arranged on the circumference of the center block, and convex tooth structures matched with the tooth grooves are arranged on the elastic arms. The elastic arm is made by plastics, certain elasticity has, protruding tooth structure on the elastic arm goes into under the elastic action of elastic arm in the tooth's socket on the connecting hole inner wall, when the lamp body is when rotating like this, protruding tooth structure on the elastic arm can loop through the individual tooth's socket on the connecting hole inner wall, thereby can produce suitable resistance to the rotation of lamp body, increase the feeling of operator when adjusting the lamp body, simultaneously through the cooperation between protruding tooth structure and the tooth's socket, also can play the spacing effect of angle to the lamp body.

Preferably, the resilient arms are integrally formed with the central block.

The utility model has the beneficial effects that: the light-emitting component is cooled and radiated by the cooling fan in an air cooling mode, and compared with the traditional mode of radiating by the radiating fins, the radiating efficiency is greatly improved, and the radiating effect is good.

Detailed Description

The utility model is further described by the following detailed description in conjunction with the accompanying drawings.

Example 1:

as shown in fig. 1 to 7, a work light with a heat dissipation fan includes a bracket 1 and a light body connected to the bracket. The lamp body 1 includes a housing 2 and a light emitting assembly 3 disposed within the housing 2. The light emitting element 3 is an LED light emitting element. A heat dissipation fan 4 for dissipating heat of the light emitting assembly 3 is further provided in the housing 2. The heat radiation fan 4 is fixed in the housing 2 by screws. The shell 2 is provided with an air inlet 7 and an air outlet 5. The air outlet 5 is arranged corresponding to the heat radiation fan 4.

The bracket 1 is U-shaped. The support 1 comprises a base 8, supporting arms 9 are arranged on two sides of the base 8, and a connecting shaft 10 is arranged on the supporting arms 9.
