Abstract

The utility model discloses a straight-down panel light which comprises a shell body, a power supply lead and a power converter. A heat dissipation aluminum plate layer, an aluminum substrate layer and a diffuser plate layer is arranged inside the shell body, wherein the heat dissipation aluminum plate layer and the aluminum substrate layer are installed in parallel, and the diffuser plate layer is fixedly installed on the heat dissipation aluminum plate layer. Multiple grooves are formed on one side of the aluminum substrate layer at intervals, wherein with light emitting diode (LED) lamps are installed in the grooves in an embedded mode. The power supply lead is connected with the LED lamps on the aluminum substrate layer through the power converter. According to the straight-down panel light, the LED lamps can be inlaid inside the grooves on the diffuser plate layer directly, meanwhile, a light guide plate which is used generally in the prior art is saved. The thickness of the straight-down panel light can be greatly reduced, and cost is reduced. Lights which are sent out by the LED lamps can be directly shined out through the diffuser plate layer. A utilization rate of the lights is improved. The light guide plate is light in weight. Service life of lamps is greatly prolonged. The straight-down panel light is easy to manufacture and beneficial for being widely popularized and applied.

Description

The straight-down negative panel light
Technical field
The utility model relates to a kind of lighting technical field, is specifically related to a kind of straight-down negative panel light.
Background technology
The LED illuminating lamp is a kind of lighting that utilizes the 4th generation green light source LED to make, have that energy consumption is low, caloric value is low, long service life, stability is high, the response time is short, environmentally safe, the advantage such as multicolor luminous, more and more widely in fields such as various indications, demonstration, decoration, backlight, general lighting and urban landscapes.the existing luminous panel light of side, the light that LED sends, enter from LGP both sides, absorbed by the reticulate structure below LGP, again via the baffle reflection below LGP, light is penetrated along the direction of LGP, due to the LGP in the luminous panel light of side, reflective printing ink and reflectance coating are in higher temperature, be easy to aging yellowing, cause light emission rate to reduce, reduce the life-span of lamp, its cost is high, LGP in the luminous panel light of side is heavier, if be arranged on ceiling, need to install as pendent lamp, be not suitable for ceiling lower office, corridor or the installation of small conference room.Therefore, along with people, the requirement of product is improved constantly and the continuous maturation in market, existing panel light can't satisfy the demand of existing market.
The utility model content
The purpose of this utility model is, life-span of for above-mentioned deficiency, provide that a kind of structural design is ingenious, reasonable, light efficiency is high, cost is low, lightweight, convenient transportation, light fixture are long and have the straight-down negative panel light that reduces light panel thickness.
For achieving the above object, technical scheme provided by the utility model is:
A kind of straight-down negative panel light, it comprises housing, power supply lead wire and supply convertor, be provided with radiation aluminium flaggy, aluminium base flaggy and diffusion flaggy in described housing, described radiation aluminium flaggy and the parallel installation of aluminium base flaggy, described diffusion flaggy is fixedly mounted on the radiation aluminium flaggy, described aluminium base flaggy one side is interval with the groove of a plurality of down dress LED lamps, and described power supply lead wire is connected with LED lamp on aluminium base flaggy by supply convertor.
The edge contour of described housing is shaped as: square, circular or oval.
The edge contour of described radiation aluminium flaggy is shaped as: square, circular or oval.
The edge contour of described aluminium base flaggy is shaped as: square, circular or oval.
The back side of described housing is provided with louvre.
The beneficial effects of the utility model are: the utility model structural design is ingenious, reasonable, light through the diffuser plate direct irradiation out, the utilization rate of light is higher, owing to not having LGP that the weight of light fixture is lowered greatly, the design industry is more flexible, has also saved cost of transportation when the cost of light fixture will be hanged down; The panel light diffuser plate of straight-down negative does not contact with heat generating spot simultaneously, and residing temperature is much lower, can make light fixture that the long life-span is arranged, and is easy to make, and is beneficial to wide popularization and application.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, a kind of straight-down negative panel light that the present embodiment provides, it comprises housing 1, power supply lead wire 2 and supply convertor 3, be provided with radiation aluminium flaggy 4, aluminium base flaggy 5 and diffusion flaggy 6 in described housing 1, described radiation aluminium flaggy 4 and the parallel installation of aluminium base flaggy 5, described diffusion flaggy 6 is fixedly mounted on radiation aluminium flaggy 4, and described aluminium base flaggy 5 one sides are interval with the groove 7 of a plurality of down dress LED lamps, and described power supply lead wire 2 is connected with LED lamp on aluminium base flaggy 5 by supply convertor 3.
The edge contour of described housing 1 is shaped as: square, circular or oval.
The edge contour of described radiation aluminium flaggy 4 is shaped as: square, circular or oval.
The edge contour of described aluminium base flaggy 5 is shaped as: square, circular or oval.
The back side of described housing 1 is provided with louvre.
In real work, the light that LED light source sends through diffusion flaggy 6 direct irradiations out, the utilization rate of light is higher, the panel light diffuser plate of straight-down negative does not contact with heat generating spot simultaneously, and residing temperature is low, can make light fixture that the long life-span is arranged, due to the cost that has saved LGP and make panel light, lightweight, be easy to make, be beneficial to wide popularization and application.
As described in the utility model above-described embodiment, adopt structure same or analogous with it and the panel light of other structure of obtaining, all in the utility model protection domain.
