The bottom shell and the cover are connected to form an LED ceiling lamp outer shell, the LED lamp beads are fixed to the LED lamp panel, the LED lamp panel is fixed to the bottom shell, the drive circuit board is arranged in an independent shell body, electronic components are arranged on the drive circuit board in a covering mode, the end, penetrating through the shell body, of a wire and the bottom shell are connected with the drive circuit board and the LED lamp panel, and a wire of the drive circuit board penetrates through the shell body and is connected with a power supply.
Description
Technical field
The utility model belongs to LED lighting field, refers to especially a kind of indoor LED lamp affixed to the ceiling.
Background technology
According to one's analysis, the power consumption of LED is only 1/10th of incandescent lamp, and nothing ultraviolet ray, radiationless in light, becomes the novel illumination product of world's first-selection.At technical elements, LED luminous efficiency is also improving constantly, and can meet general lighting needs completely, and therefore, LED lamp now obtains the application developing widely.
But in actual use, through detecting and summing up and find, although LED lamp can reach the needs of illumination, do not reach theoretic energy-saving effect, it is actual energy-conservation is only 50% left and right, does not also reach theoretic service life.By analysis, find, two reasons that mainly contain that cause this situation, one is that heat radiation does not reach theoretical requirement, no matter this is because be LED lamp pearl or the electronic component with it in supporting driving power, when variations in temperature, also can there is certain change in its performance parameter.Another is the increase that the design of drive circuit causes actual power consumption amount, if this is mainly guarantee circuit steady, just need to increase electronic component, and each electronic component all has the consumption of energy or efficiency impossible 100% to transform in the course of the work, like this, the more multicircuit power consumption of electronic component is just higher.Conversely, if reduce electronic component, although energy consumption can reduce, the curtage fluctuation of circuit strengthens, and the luminescent properties of LED is exerted an influence, and reduces the luminous efficiency of LED.Around these two problems, most of professionals are making great efforts to overcoming these technical barriers now.
Design to LED light fixture, is mainly that drive circuit is placed in same housing with LED lamp pearl now, and such scheme is with the obvious advantage, is exactly easy to install, just can not transform and can directly replace incandescent lamp or fluorescent lamp.But also there is obvious defect in such design, be exactly the bad solution of heat dissipation problem, although the existing LED light fixture using is all used radiator, radiating effect is unsatisfactory, particularly when the temperature of environment is higher, obvious on the impact in the efficiency of LED light fixture and service life.
Utility model content
The purpose of this utility model be solve drive circuit with LED lamp pearl be positioned at same housing internal cause radiating effect affect LED efficiency and service life problem.
The utility model is achieved through the following technical solutions:
An indoor LED ceiling light, includes LED lamp pearl, drain pan, face shield, LED lamp plate and drive circuit board; Described drain pan and face shield connect to form LED ceiling light shell, and described LED lamp pearl is fixed on LED lamp plate, and LED lamp plate is fixed on drain pan; Described drive circuit board is arranged in a separate housing, and electronic component face shield is on drive circuit board, and wire is connected drive circuit board and LED lamp plate through housing one end with drain pan; Drive circuit board has wire to pass housing connection power supply.
In described housing, be provided with thermal plastic insulation, drive circuit board immerses in heat-conducting glue.
Described LED lamp plate is screwed on drain pan.
Between described face shield and drain pan for being threaded or clamping.
The utility model beneficial effect is compared with the existing technology:
Pass through the technical program, drive circuit board is arranged at LED lamp housing and is not connected with LED lamp housing outward, and the heat of LED lamp pearl can not have influence on drive circuit board like this, therefore, drive circuit can be stable for LED lamp pearl provides electric current, can stablize the luminous efficiency of LED lamp pearl.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The specific embodiment
Describe by the following examples the technical solution of the utility model in detail, should be understood that, following embodiment is only exemplary, only can be used for explaining and explanation the technical solution of the utility model, and can not to be interpreted as is the restriction to technical solutions of the utility model.
Shown in Fig. 1, a kind of indoor LED ceiling light, includes LED lamp pearl 3, drain pan 1, face shield 4, LED lamp plate 2 and drive circuit board (not shown); Described drain pan and face shield are threaded connection or clamping connects to form LED ceiling light shell, and drain pan is fixed on indoor wall or ceiling by screw or bolt.Drain pan be metal material and be conducive to heat radiation, LED lamp pearl is fixed on LED lamp plate, LED lamp plate is screwed on drain pan; Drive circuit board is arranged in a separate housing, and housing can be the metal material of heat conduction or the resin material of heat conduction, and electronic component face shield, on drive circuit board, is provided with thermal plastic insulation in housing, and drive circuit board immerses in heat-conducting glue.
Wire is connected drive circuit board and LED lamp plate through housing one end with drain pan; Drive circuit board has wire to pass housing connection power supply.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is by claims and be equal to and limit.
