Description
Technical field
The utility model relates to a kind of light fixture, particularly a kind of LED bulkhead lamp capable that is used for the factory floor intraoral illumination.
Background technology
At present, existing workshop lighting is generally incandescent lamp, brightness is darker, because the lighting in the workshop will continue luminous lighting, still, the service life of incandescent lamp is shorter, brightness is lower, and incandescent lamp use alternating current is luminous, the light instability, bring stimulation to eye, cause eye fatigue.
Summary of the invention
That the purpose of this utility model is is short at the existing bulkhead lamp capable life-span described in the background technology, brightness is low, the light problem of unstable, and a kind of LED bulkhead lamp capable that can solve foregoing problems is provided.
The technical scheme that realizes goal of the invention of the present utility model is as follows:
A kind of LED bulkhead lamp capable, it comprises lamp panel, rear lamp cover, be arranged at the circuit board on the lamp panel inner bottom surface, the power processor that is arranged at the LED light emitting diode on the circuit board and is connected by lead with circuit board, described circuit board is aluminium base circuit board, described LED light emitting diode is SMD LED light-emitting diode chip for backlight unit, described power processor is the constant-current source processor, the lamp panel outer bottom is connected with fin, the constant-current source processor is arranged on the upper surface of fin, the fin lower surface is fixedlyed connected with the lamp panel outer bottom, and rear lamp cover is fixedlyed connected with lamp panel.
Described fin is the fin of aluminium material, and this fin lower surface is the plane, and upper surface is provided with the number of plate-shaped projection.
Described lamp panel is the lamp panel of aluminium material.
Described light cover upper end is connected with and is used for holder that bulkhead lamp capable is fixed.
Be provided with the high thermal conductive silicon film between described LED light-emitting diode chip for backlight unit and the aluminium base circuit board.
The beneficial effects of the utility model are for comprising lamp panel because of LED bulkhead lamp capable of the present utility model, rear lamp cover, be arranged at the circuit board on the lamp panel inner bottom surface, the power processor that is arranged at the LED light emitting diode on the circuit board and is connected by lead with circuit board, described circuit board is aluminium base circuit board, described LED light emitting diode is SMD LED light-emitting diode chip for backlight unit, because adopt the LED light-emitting diode chip for backlight unit as light emitting source, power processor is the constant-current source processor, therefore, the lamplight brightness height, and there is not a stroboscopic, light is stable, the eye health that is of value to the personnel of work under the light, and be far longer than the service life of incandescent lamp the service life of LED light-emitting diode chip for backlight unit, therefore, the longer service life of LED bulkhead lamp capable.In order to improve the heat radiation of LED light-emitting diode chip for backlight unit, prolong the service life of LED light-emitting diode chip for backlight unit, the lamp panel outer bottom is connected with fin, and in order to improve the heat radiation of constant-current source processor, the constant-current source processor is arranged on the upper surface of fin.The heat that produces when the LED light-emitting diode chip for backlight unit is luminous at first conducts on the aluminium base circuit board by the high thermal conductive silicon film, conduct on the lamp panel by the heat transmission then, be transmitted to then with fin that lamp panel is connected on, by fin heat is dispersed in the external environment condition.The constant-current source processor is arranged on the fin, and therefore, the heat that the constant-current source processor produces also can make the LED bulkhead lamp capable reach a good heat-radiation effect by fin conductive to external environment condition.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Among the figure, 1 is lamp panel, and 2 is rear lamp cover, and 3 is circuit board, and 4 is the LED light-emitting diode chip for backlight unit, and 5 is the constant-current source processor, and 6 is fin, and 7 is holder, and 8 is the high thermal conductive silicon film.
The specific embodiment
With reference to a kind of LED bulkhead lamp capable shown in Figure 1, it comprises lamp panel 1, rear lamp cover 2, be arranged at the circuit board 3 on lamp panel 1 inner bottom surface, the power processor that is arranged at the LED light emitting diode on the circuit board 3 and is connected by lead with circuit board 3, described circuit board 3 is aluminium base circuit board 3, described LED light emitting diode is SMD LED light-emitting diode chip for backlight unit 4, described power processor is a constant-current source processor 5, lamp panel 1 outer bottom is connected with fin 6, constant-current source processor 5 is arranged on the upper surface of fin 6, fin 6 lower surfaces are fixedlyed connected with lamp panel 1 outer bottom, and rear lamp cover 2 is fixedlyed connected with lamp panel 1.In order to improve the radiating effect of LED bulkhead lamp capable, described fin 6 is the fin 6 of aluminium material, and these fin 6 lower surfaces are the plane, and upper surface is provided with the number of plate-shaped projection; Described lamp panel 1 is the lamp panel 1 of aluminium material; Described light cover upper end is connected with and is used for holder 7 that bulkhead lamp capable is fixed.Because the LED light-emitting diode chip for backlight unit 4 of patch-type is when welding, can there be certain space between bottom and the aluminium base circuit board 3, therefore, in order to improve the heat-conducting effect between LED light-emitting diode chip for backlight unit 4 and the aluminium base circuit board 3, be provided with high thermal conductive silicon film 8 between described LED light-emitting diode chip for backlight unit 4 and the aluminium base circuit board 3.
