Abstract
The utility model discloses a LED lamp and comprises a base. The base is connected with a LED heat radiating shell, a LED is arranged in the LED heat radiating shell, a circuit connected with the LED is arranged between the base and the LED heat radiating shell, and the utility model is characterized in that the external wall of the LED heat radiating shell is provided with a plurality of longitudinal heat radiating grooves and a plurality of horizontal heat radiating grooves intersected with the longitudinal heat radiating grooves. A plurality of longitudinal heat radiating grooves are distributed on the external wall of the LED heat radiating shell uniformly, and the size of each longitudinal heat radiating groove gradually becomes smaller from a notch to the bottom of the groove. Therefore, heat radiating area is greatly increased, wind can be blown into the heat radiating groove more easily and the heat radiating effect is improved.
Description
[technical field]
The utility model relates to a kind of LED lamp, relates in particular to a kind of LED lamp with heat-dissipating casing.
[background technology]
The LED lamp becomes indispensable ornament or illuminations in people's life now, LED lamp power is very big, when work, can produce a large amount of heats, if can not in time these heats be distributed, will the service behaviour of LED be exerted an influence so, even burn, for these heats being distributed, people have developed heat-dissipating casing, but the radiating efficiency of existing heat-dissipating casing is not high, how to improve the radiating efficiency of LED lamp, to be a problem that is worth solution, for this reason, design the utility model.
[utility model content]
The utility model has overcome the deficiency of above-mentioned technology, and a kind of LED lamp of good heat dissipation effect is provided.
For achieving the above object, the utility model has adopted following technical proposal:
A kind of LED lamp, include base, on base, be connected with the LED heat-dissipating casing, in the LED heat-dissipating casing, LED is installed, between base and LED heat-dissipating casing, be provided with the circuit board that is connected with LED, it is characterized in that: a plurality of heatsink transverse grooves that the outer wall of LED heat-dissipating casing is provided with a plurality of vertical radiating grooves and intersects with vertical radiating groove.
Aforesaid a kind of LED lamp is characterized in that: vertically the size of radiating groove is diminished to bottom land gradually by notch.
Aforesaid a kind of LED lamp is characterized in that: a plurality of vertical radiating grooves are distributed on the outer wall of LED heat-dissipating casing.
Aforesaid a kind of LED lamp is characterized in that: plastic lens also is installed above LED, is provided with the plastics reflector between plastic lens and LED.
The beneficial effects of the utility model are: because the outer wall of LED heat-dissipating casing is provided with a plurality of vertical radiating grooves and a plurality of heatsink transverse groove.This has increased the area of heat radiation widely, and vertically radiating groove is distributed on the outer wall of LED heat-dissipating casing, and the size of each vertical radiating groove diminishes to bottom land gradually by notch, can make that wind is easier to be blown in vertical radiating groove, has increased the effect of dispelling the heat.
[description of drawings]
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a LED heat-dissipating casing structural representation one of the present utility model;
Fig. 3 is a LED heat-dissipating casing structural representation two of the present utility model.
[specific embodiment]
As shown in Figure 1, a kind of LED lamp, include base 1, on base 1, be connected with LED heat-dissipating casing 2, LED 3 is installed in LED heat-dissipating casing 2, be provided with the circuit board 4 that is connected with LED 3 between base 1 and LED heat-dissipating casing 2, the lead 5 on this circuit board 4 is connected with LED 3 by the hole 6 on the LED heat-dissipating casing 2.A plurality of heatsink transverse grooves 22 that the outer wall of LED heat-dissipating casing 2 is provided with a plurality of vertical radiating grooves 21 and intersects with vertical radiating groove 21.
In the utility model, the outer shape of LED heat-dissipating casing 2 is a truncated cone-shaped, in order to increase the radiating effect of LED, a plurality of heatsink transverse grooves 22 that the outer wall of LED heat-dissipating casing 2 is provided with a plurality of vertical radiating grooves 21 and intersects vertically with vertical radiating groove 21.This has increased the area of heat radiation widely, and all vertical radiating grooves 21 are distributed on the outer wall of LED heat-dissipating casing 2, and the size of each vertical radiating groove 21 is diminished to bottom land gradually by notch, can make that wind is easier to be blown in vertical radiating groove 21, has increased the effect of heat radiation.
