Abstract
The utility model discloses an LED (light-emitting diode) bulkhead lamp comprising a lamp head, a lamp shade and an LED lamp, wherein the lamp shade is installed on a radiator, and the LED lamp is arranged in the lamp shade. The LED bulkhead lamp is characterized in that the lamp head is internally provided with a cooling fan used for cooling the LED lamp. The radiator is internally provided with a temperature control protection device which is electrically connected with a power supply. The radiator is made of 6063 aluminum. The 6063 aluminum is adopted as heat conductive material, so that the heat conductive performance is greatly improved. Heat is finally transferred in the air, so that the radiating performance is greatly improved by additionally arranging the cooling fan on the limited heat transfer area; in order to avoid the phenomenon that a lamp bead is burnt caused by overhigh temperature due to damage of the fan, an overtemperature protection device is adopted; when the temperature is higher than 65 DEG C, the overtemperature protection device is automatically switched off so as to protect the LED lamp bead; and when the temperature drops, the temperature control protection device is automatically switched on so as to lead the lamp lead to emit light.
Description
Technical field
The utility model relates to a kind of LED bulkhead lamp capable, and temperature control protection LED bulkhead lamp capable is grown, had to specifically a kind of good heat dissipation, lamp pearl life-span.
Background technology
Be undoubtedly fatal shortcoming for too high variation of LED lamp pearl temperature with electric current, especially quite responsive to temperature, show according to each big LED lamp pearl manufacturer information, light decay was quite serious when temperature reached 75 °, the above LED lamp pearl caloric value of high-power 50W (10 ℃/W) under the big relatively situation, it is not reach heat radiation far away to require that prior art is utilized die casting aluminium (A380) natural heat dissipation mode, has shortened the life-span of LED greatly.The LED bulkhead lamp capable all has the high and short situation of life-span that causes of temperature more than power 50W, because air natural heat dissipation coefficient (3-10 °/W of the natural convection air coefficient of heat transfer (M
2. ℃) do not reach the heat radiation requirement, make the lamp pearl be under the high temperature work for a long time, add and do not have temperature protective device, will cause too high the burning out of lamp pearl temperature.
Summary of the invention
The purpose of this utility model provides a kind of good heat dissipation, lamp pearl life-span length, has the LED bulkhead lamp capable of temperature control protection.
The purpose of this utility model is achieved through the following technical solutions.
A kind of LED bulkhead lamp capable comprises lamp holder, lampshade and LED lamp, and lampshade is installed on the lamp holder, and the LED lamp is installed in the lampshade, it is characterized in that: the radiator fan that is used for the heat radiation of LED lamp is installed in the described lamp holder.
The temperature control protective device is installed in the described radiator, and the temperature control protective device is electrically connected with power supply.
Described radiator is made by 6063 aluminium materials.
The utility model compared with prior art has the following advantages:
The utility model adopts 6063 aluminium materials as Heat Conduction Material, improves heat conductivility greatly.Heat finally will pass in the air and go; increasing fan on limited heat transfer area dispels the heat; make thermal diffusivity improve greatly; the temperature that causes is too high to cause the lamp pearl to burn out for fear of damaging owing to fan; this structure has also adopted the over-temperature protection device, and protective device can automatic powered-down protection LED lamp pearl when temperature surpasses 65 °.Attemperating unit reclosed power supply automatically when temperature descended, and the lamp pearl is from newly light.
Description of drawings
Fig. 1 is the structural representation of the utility model LED bulkhead lamp capable.
The specific embodiment
Below in conjunction with accompanying drawing the utility model LED bulkhead lamp capable is described in further detail.
As shown in Figure 1, LED bulkhead lamp capable described in the utility model mainly is made up of with LED lamp 3 lamp holder 1, lampshade 2.Lampshade is installed on the radiator, and the LED lamp is installed in the lampshade.The middle part of lamp holder is equipped with the radiator fan 4 that is used for the heat radiation of LED lamp, and the bottom of radiator fan is equipped with temperature control protective device 5, and the temperature control protective device is electrically connected with power supply.Radiator fan surcoat heronsbill radiator 6.Lamp holder top is equipped with electrical box.Radiator is made by 6063 aluminium materials, and lampshade bottom is provided with the acrylic panel.Adopt 6063 aluminium materials as Heat Conduction Material, improve heat conductivility greatly.Heat finally will pass in the air and go; increasing fan on limited heat transfer area dispels the heat; make thermal diffusivity improve greatly; the temperature that causes is too high to cause the lamp pearl to burn out for fear of damaging owing to fan; this structure has also adopted the over-temperature protection device, and protective device can automatic powered-down protection LED lamp pearl when temperature surpasses 65 °.Attemperating unit reclosed power supply automatically when temperature descended, and the lamp pearl is from newly light.
