Abstract

The utility model discloses an embedded LED (Light Emitting Diode) lamp. The embedded LED lamp comprises a lamp bracket, light diffusion plates, LED light sources and a power supply, wherein the lamp bracket is of an all-in-one structure and is provided with upwardly-sunk lampshades, the LED light sources are fixed in the lampshades, the light diffusion plates are arranged on the lampshades, and the power supply is fixed on the lamp bracket. Due to the all-in-one structure of the lamp bracket, the heat resistance is lowered, the heat-conducting rate for the LED light sources is accelerated, the cooling efficiency is high, and a cooling structure does not need to be additionally designed; and furthermore, the all-in-one lamp bracket is simple in structure, and the mechanical strength and weight of the product are greatly increased, so that the embedded LED lamp can be more solid and is convenient to mount.

Description

Flush type LED lamp

Technical field

The utility model relates to LED lamp field, particularly a kind of flush type LED lamp.

Background technology

Flush type LED lamp in order to be installed on general ceiling or the light steelframe has installation, maintenance conveniently, and the characteristic that power saving, high brightness and volume are little significantly improves the illumination efficiency of the light steelframe lighting of ceiling and reduces power consumption.(LightEmittinDiode LED) as solid state light emitter of new generation, has numerous advantages such as long, energy-efficient, environmental protection of life-span to its core component light emitting diode, is widely applied to demonstration, lighting field.

The core of LED is a PN junction, and the electronics and the hole of annotating the people directly convert electric energy into luminous energy at the PN junction compound tense, but the luminous energy of not all conversion all enough is transmitted into outside the LED; It can be absorbed sheet in PN junction and epoxy resin/silica gel inside, and to transform this heat energy of heat energy be that light fixture is produced huge side effect, if can not efficiently radiates heat, can make the rising of LED internal temperature; Temperature is high more; The luminous efficiency of LED is low more, and the life-span of LED is short more, under the serious situation; Can cause the LED wafer to lose efficacy at once, so heat radiation is still the huge obstacle that great power LED is used.

The lampshade of existing flush type LED lamp and lamp bracket are for dividing body structure, and assembly structure is complicated; Simultaneously, divide body structure to have a strong impact on lampshade and lamp bracket, need the specialized designs radiator structure, increased the cost of this flush type LED lamp and the complexity of structure the efficiently radiates heat of LED.

The utility model content

The technical problem that the utility model solves provides a kind of flush type LED lamp of simple in structure, easy to assembly, good heat dissipation effect.

For achieving the above object, according to the utility model a kind of flush type LED lamp is provided, comprising: lamp bracket, light diffusing sheet, led light source and power supply, the lamp bracket structure that is formed in one has the upwards lampshade of depression; Led light source is fixed in the lampshade; Light diffusing sheet is located on the lampshade; Power supply is fixed on the upper surface of lamp bracket.

Further, the cross section of lampshade in echelon, power supply is fixed on the top of trapezoidal lampshade.

Further, light diffusing sheet is connected on the lamp bracket.

Further, the material of light diffusing sheet is glass, PMMA, PC or PET.

According to the technical scheme of the utility model and since the reduction of lamp bracket integrated formed structure thermal resistance, quickened capacity of heat transmission to led light source, radiating efficiency is high, and need not the otherwise designed radiator structure; In addition, integrated lamp bracket is simple in structure, significantly improves the mechanical strength and the weight of product, makes that this flush type LED lamp is more solid, and easy for installation.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of the specific embodiment.

Referring to Fig. 1 and Fig. 5, this flush type LED lamp comprises: lamp bracket 1, light diffusing sheet 2, led light source 3 and power supply 4.Wherein, the rectangular configuration that lamp bracket 1 is formed in one can be metal species sheet material or heat radiation plastics forming; Periphery has upwardly extending embedding frame, goes into formula applicable to the lifting of the ceiling of the light steelframe of all standard sizes and down and installs; The middle part has three lampshades 11 that laterally arrange side by side; This lampshade 11 is upwards caved in by the front (below among the figure) of lamp bracket 1 and forms; Cross section is (as shown in Figure 2) in echelon; Trapezoidal the right and left and bottom surface are designed to the special-shaped light distribution curve structure, and this structure not only can reflex to the field of illumination with most light, can the spot light light of dazzling led light source 3 be transferred to soft area source light again; Effectively solve glare problem and often protect optimal illumination efficient, so provide the life-span long, power consumption is little and the LED green illumination of compliance with environmental protection requirements; Trapezoidal both sides have the blocked hole (not marking among the figure) of a plurality of confession light diffusing sheet 2 clampings; In addition, there is the hole for hoist position (not shown) of standard the both sides of lamp bracket 1.

As shown in Figure 3, led light source 3 gums are fixed on this trapezoidal top (upper base), can be by LED luminescence component such as direct insertion, SMD, or led chip is processed on the aluminium base with COB (CHIP ON BOARD) and forms.Like Fig. 4 and shown in Figure 5; Light diffusing sheet 2 is a rectangle; The upper surface periphery has a plurality of clampings of cooperating with the blocked hole of lamp bracket 1 21; Be located on the lampshade 11, can be the material that glass, PMMA (lucite), PC (Merlon) or PET (PETG) etc. have high transmission rate and process.Power supply 4 is fixed on the upper surface of lamp bracket 1, does not have in three grooves between the lampshade 11, is led light source 3 power supplies.

Since the reduction of lamp bracket 1 integrated formed structure thermal resistance, quickened capacity of heat transmission to led light source 3, radiating efficiency is high, and need not the otherwise designed radiator structure; In addition, integrated lamp bracket 1 is simple in structure, significantly improves the mechanical strength and the weight of product, makes that this flush type LED lamp is more solid, and easy for installation.

More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
