A kind of LED lamp affixed to the ceiling
Technical field
The utility model relates to a kind of lighting, particularly a kind of LED lamp affixed to the ceiling.
Background technology
LED lamp affixed to the ceiling has the various advantages such as specular removal, life-span length, environmental protection, brightness-adjustable and colour temperature, just progressively replaces traditional lighting, is applied in more and more widely in the illumination of the occasion such as indoor, boats and ships.
LED lamp affixed to the ceiling generally includes lamp panel and is fixed on the substrate in lamp panel, LED lamp bead is fixed on substrate for illumination, in the LED lamp affixed to the ceiling that existing LED lamp affixed to the ceiling is particularly circular, for making uniform light, usually the substrate of the circular ring type of multiple concentric setting can be adopted as light source, like this, the substrate using multiple different size is just needed in a LED lamp affixed to the ceiling, and in process of production, due to transport, store, the reasons such as damage or defect ware, the quantity of the substrate of all size usually cannot be consistent with the quantity needed, so just there will be the situation that the substrate of certain specification is superfluous or not enough, impact is produced, cause the wasting of resources, and the substrate of all size needs to use different moulds, the equipment that needs also corresponding during installation are different, improve production cost, also be not easy to maintenance when breaking down simultaneously, and owing to there is interval between each LED lamp bead, its gross area of the substrate of this annular cannot adjust according to the quantity of LED lamp bead, be not easy to reduce production cost.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide a kind of LED lamp affixed to the ceiling being convenient to produce, effectively can lower production cost and cut the waste.
The utility model is the technical scheme that its technical problem of solution adopts:
A kind of LED lamp affixed to the ceiling, comprises lamp panel and is fixed on the light source on lamp panel, and described light source comprises some substrates and is arranged on the some LED lamp bead on substrate, and each substrate shape is identical and with the center of lamp panel for basic point radially distributes.
Preferably, each substrate is identical " T " font structure, and those substrates are uniformly distributed around lamp panel center, and the widthwise edge of each substrate is away from the center of lamp panel, and the longitudinal edge of each substrate points to the center of lamp panel.
As improvement, described lamp panel offers the groove for hold each substrate suitable with each substrate.
Further, described lamp panel wherein heart position also offers an accommodating cavity be communicated with each groove.
Further, also comprise and to conduct electricity the supply unit be connected with each base plate bottom, this supply unit is located in described accommodating cavity.
The beneficial effects of the utility model are: because substrate shape each in the utility model is identical, such substrate just has versatility, just the substrate using a kind of specification is only needed in a kind of LED lamp affixed to the ceiling, there will not be the problem that the substrate ratio of all size is in the past not adaptive, greatly facilitate production and processing and transport; Each substrate with the center of lamp panel for basic point radially distributes, so just, can power to each substrate at the center of lamp panel simultaneously, be convenient to wiring, and make this LED lamp affixed to the ceiling more neat and artistic, by the adjustment position of LED lamp bead on substrate, just it can be made to be arranged in the same circular ring type of LED lamp affixed to the ceiling in the past, other desired situation can certainly be arranged in; According to the brightness needed for LED lamp affixed to the ceiling, can increase and decrease the quantity of substrate neatly to adjust quantity and the density of LED lamp bead, effectively can reduce the waste of substrate, energy-conserving and environment-protective, effectively reduce production cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is overall structure figure of the present utility model;
Fig. 2 is explosive view of the present utility model.
Detailed description of the invention
See figures.1.and.2, a kind of LED lamp affixed to the ceiling, comprise lamp panel 1 and be fixed on the light source 2 on lamp panel 1, some LED lamp bead 22 that light source 2 comprises some substrates 21 and arranges on the base plate (21, each substrate 21 shape is identical and with the center of lamp panel 1 for basic point radially distributes.Each substrate 21 shape is identical, and such substrate 21 just has versatility, just only needs the substrate 21 using a kind of specification in a kind of LED lamp affixed to the ceiling, there will not be the problem that substrate 21 ratio of all size is in the past not adaptive, facilitates production and processing and transport; Each substrate 21 with the center of lamp panel 1 for basic point radially distributes, so just, can power to each substrate 21 at the center of lamp panel 1 simultaneously, be convenient to wiring, and make this LED lamp affixed to the ceiling more neat and artistic, according to the brightness needed for LED lamp affixed to the ceiling, the quantity that can increase and decrease substrate 21 neatly, to adjust quantity and the density of LED lamp bead 22, effectively can reduce the waste of substrate 21, energy-conserving and environment-protective, effectively reduce production cost.
In the present embodiment, substrate 21 is " T " font structure, and those substrates 21 are uniformly distributed around the center of lamp panel 1, and the widthwise edge of each substrate 21 is away from lamp panel 1 center, and the longitudinal edge of each substrate 21 points to lamp panel 1 center.This shape of substrate 21 and arrangement mode be convenient to distinguish substrate 21 two ends, be easy to location and installation and comparatively neat and artistic, be convenient to make each LED lamp bead 22 form conventional circular arrangement simultaneously, because the girth by lamp panel 1 outer rim is larger, the LED lamp bead 22 that usual needs are more, therefore the widthwise edge of substrate 21 is placed in lamp panel 1 outer rim, is convenient to arrange more LED lamp bead 22, effectively can reduces the area of substrate 21, reduce the materials'use of substrate 21, reduce costs.Certain substrate 21 also can be other shapes such as strip, waveform, triangle.
Lamp panel 1 offers the groove 11 for hold each substrate 21 suitable with each substrate 21, be convenient to location and fixing each substrate 21, lamp panel 1 wherein heart position also offers an accommodating cavity 12 be communicated with each groove 11, this accommodating cavity 12 may be used for placing supply unit and the power line for being connected supply unit and substrate 21, power line is avoided to expose, more attractive in appearance and can use safety be ensured.
The foregoing is only preferred embodiments of the present utility model, as long as the technical scheme realizing the utility model object with basic same approach all belongs within protection domain of the present utility model.
