Description

a lamp

technical field

The utility model relates to a lamp.

Background technique

At present, LED (Light Emitting Diode) has been widely used in lamps and lanterns. For smaller power lamps, it generates less heat and will not affect the normal operation of lamps. However, when working with a relatively high-power LED, a large amount of heat will be generated. If the heat is not dissipated in time after the heat accumulates on the pins of the LED, it will burn out the LED lamp and affect the life of the product.

As shown in FIG. 1 , a common lamp heat dissipation module 1 currently on the market includes a base 11 and heat sinks 12 , and heat dissipation channels 13 with uniform width are formed between adjacent heat sinks 12 . After the heat generated by the LED is conducted to the base 11 , the base 11 conducts the heat to the heat sink 12 , and dissipates heat through the surface of the heat sink 12 . The disadvantage of this heat dissipation module is that the uniform heat dissipation channel 13 has poor convection with the air, and when the heat is large, it cannot cool down in time, which affects the heat dissipation effect.

Utility model content

The technical problem to be solved by the utility model is to provide a lamp capable of enhancing heat dissipation effect.

In order to solve the above technical problems, the utility model provides a lamp, which includes a housing, a light source module and a heat dissipation module, the housing is fixed on the heat dissipation module, the light source module is located in the housing and attached to the heat dissipation module on the module. The heat dissipation module includes a base and several heat dissipation fins, the heat dissipation fins are fixed on one side of the base, and a heat dissipation channel is formed between adjacent heat dissipation fins, and the heat dissipation channel extends from the bottom to the top opening. The width gradually increases.

The width of the cooling channels formed by the cooling fins gradually increases from the bottom to the top opening, which makes it easier for air to enter the cooling channels and increases the fluidity of the air. When the heat is conducted to the heat sink, the heat of the heat sink is taken away due to the contact of the air with the heat sink, so that when the fluidity of the air is enhanced, the heat exchange speed with the outside world is accelerated, and the heat dissipation effect of the heat sink is enhanced. Therefore, compared with the prior art, after the lamp adopts the heat dissipation module, the heat generated by the light source module can be dissipated more easily, preventing heat accumulation from affecting the service life of the light source module.

Detailed ways

In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Please refer to Fig. 2 and Fig. 3, the embodiment of the present utility model provides a lamp, including a housing 21, a light source module 22 and a heat dissipation module 23, the housing 21 is fixed on the heat dissipation module 23, and the light source module 22 is located in the housing 21 , and the heat dissipation module 23 is pasted on the light source module 22 .

Please refer to FIG. 4 and FIG. 5 together. The heat dissipation module 23 includes a heat conduction block 230 , a base 231 and a plurality of heat dissipation fins 232 , and the heat dissipation fins 232 are fixed on the base 231 . A heat dissipation channel 233 is formed between adjacent heat dissipation fins 232 , wherein the width of the heat dissipation channel 233 gradually increases from the bottom to the top opening, so that air can enter the heat dissipation channel 233 more easily and increase the fluidity of the air.

Specifically, the above-mentioned heat dissipation module 23 is integrally formed of aluminum material with good thermal conductivity, so as to avoid affecting the heat conduction effect due to different materials of the heat dissipation module 23 . The cooling fins 232 extend vertically downward from the lower surface of the base 231 , and the intervals between adjacent cooling fins 232 are uniform (that is, the width of the heat channel 233 is uniform). In order to further enhance the heat dissipation effect, as shown in Figure 5, the two side surfaces of the heat sink 232 can be waved in its height direction, so that the surface area of the heat sink 232 can be increased, and the contact with the heat sink 232 can be increased when the air flows. the contact area.

The heat conduction block 230 is located on the other side of the base 231 opposite to the heat sink 232 , and is attached to the bottom surface of the LED light source module 22 . When the LED is turned on, the heat generated by it is conducted from the bottom of the light source module 22 to the heat conduction block 230 , and the heat is conducted to the base 231 and the heat sink 232 through the heat conduction block 230 in turn.

The casing 21 is funnel-shaped, so that the side wall and the bottom surface of the casing 21 form a certain inclination angle. In this embodiment, the cross-section of the casing 21 is rectangular. A through hole 211 corresponding to the shape of the light source module 22 is opened on the bottom surface of the rectangle, and the light source module 22 is embedded in the through hole 211 . In order to make the light emitted by the light source LED of the light source module 22 pass through the side wall of the housing 21 to produce better light-gathering effect, the light source module 22 is arranged at the center of the bottom surface of the housing 21 .

A wire through hole 212 is opened on the side wall of the housing 21 , and the wire through hole 212 is used for passing a wire (not shown in the figure), and the wire is connected to the light source module 22 . In this way, it is prevented that the wires are affected by heat due to passing out from the bottom of the light source module 22 , and the effect of thermoelectric separation is achieved.

The width of the cooling channel 233 formed by the cooling fins 232 gradually increases from the bottom to the top opening, so that air can enter the cooling channel 233 more easily, increasing the fluidity of the air. After the heat conducts to the cooling fins 232, the heat of the cooling fins 232 is taken away due to the contact of the air with the cooling fins 232, so that when the fluidity of the air increases, the exchange speed of the heat with the outside world is accelerated, and the performance of the cooling fins 232 is enhanced. heat radiation. Therefore, compared with the prior art, the heat dissipation module 23 used in the lamp makes it easier to dissipate the heat generated by the light source module 22 , preventing heat accumulation from affecting the service life of the light source module 22 .
