Abstract
The utility model relates to an LED floodlight. The LED floodlight comprises a lamp base and a heat sink that is connected with the lamp base and a light emitting module is arranged in the heat sink. The LED lamp floodlight is characterized in that the side wall of the heat sink is provided with a groove with the inside and outside are connected and the groove extends upwardly to the top surface of the heat sink. The inside and outside of the heat sink are connected through the groove in the side wall of the heat sink, so that the air flowability is increased to obtain good heat dissipation. And the cost is reduced, as the material is saved owing to the groove.
Description
Technical field
The utility model relates to a kind of lighting, especially relates to a kind of LED floodlight.
Background technology
Floodlight is a kind of lighting apparatus commonly used during photography or stage set are arranged, traditional floodlight mostly adopts osram lamp or sodium vapor lamp as lighting source, and its shortcoming is that luminous efficiency is low, power consumption is high, service life is short.Along with progress and the development of LED technology, begin to replace gradually the floodlight of conventional light source as the LED floodlight of lighting source with light emitting diode.But along with the high-capacity LED floodlight is more and more in vogue, the heat that LED produces is also increasing, and radiating effect is poor to become existing most LED floodlight institute urgent problem.
Summary of the invention
The utility model provides the bar-shaped trough that a kind of sidewall at radiator is interlinked to the outside in being provided with and has had the LED floodlight of better heat dispersion; Solve the poor problem of radiating effect that exists in the prior art.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of LED floodlight, comprise lamp socket and the radiator that is connected with on it, be provided with light emitting module in the radiator, it is characterized in that: the bar-shaped trough that is interlinked to the outside in the sidewall of described radiator is provided with, and bar-shaped trough extends upwardly to the end face of radiator.Offer bar-shaped trough by the sidewall at radiator so that radiator in be interlinked to the outside, increased air flow property, have preferably thermal diffusivity.Simultaneously, materials have been saved in offering of bar-shaped trough, are conducive to reduce cost.
As preferably, described bar-shaped trough is vertical setting with the sidewall of radiator.Be conducive to improve the air flow property of radiator, radiating effect is better.
As preferably, described bar-shaped trough is provided with 3 at least, and bar-shaped trough is evenly distributed at the sidewall of radiator.A plurality of bar-shaped troughs are evenly distributed on the sidewall of radiator, are conducive to heat radiation.
As preferably, be provided with cooling pad between described light emitting module and the radiator.The heat that is beneficial to the light emitting module generation that is provided with of cooling pad promptly is delivered on the radiator, improves heat dispersion.
Therefore, the utility model has following characteristics compared to existing technology: 1. simple in structure, reasonable in design; 2. offer bar-shaped trough by the sidewall at radiator so that radiator in be interlinked to the outside, increased air flow property, have preferably thermal diffusivity; 3. offering of bar-shaped trough saved materials, reduces cost.
Description of drawings
Accompanying drawing 1 is the explosive view of a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: see Fig. 1, a kind of LED floodlight comprises lamp socket 1 and the radiator 2 that is connected with on it, also be provided with LED in the lamp socket 1 and drive 8, LED drives 8 and is connected with light emitting module 3 wires, and the top of light emitting module 3 is provided with lens 6 and retainer ring 7, and retainer ring 7 and radiator 2 fix.Be provided with light emitting module 3 in the radiator 2, the bar-shaped trough 4 that is interlinked to the outside in the sidewall of radiator 2 is provided with, and bar-shaped trough 4 extends upwardly to the end face of radiator 2.Offer bar-shaped trough by the sidewall at radiator so that radiator in be interlinked to the outside, increased air flow property, have preferably thermal diffusivity.Simultaneously, materials have been saved in offering of bar-shaped trough, are conducive to reduce cost.
Bar-shaped trough 4 is vertical setting with the sidewall of radiator 2, is conducive to improve the air flow property of radiator, and radiating effect is better.
Bar-shaped trough 4 is provided with 3 at least, and bar-shaped trough 4 is evenly distributed at the sidewall of radiator 2, and a plurality of bar-shaped troughs are evenly distributed on the sidewall of radiator, is conducive to heat radiation.
Be provided with cooling pad 5 between light emitting module 3 and the radiator 2, the heat that is beneficial to the light emitting module generation that is provided with of cooling pad promptly is delivered on the radiator, improves heat dispersion.
It is apparent to one skilled in the art that the utility model can be changed into various ways, and such change is not thought and broken away from scope of the present utility model.What all were such will be included within the scope of this claim the apparent modification of described those skilled in the art.
