Abstract

The utility model discloses an LED tube lamp which comprises an installation support and a lamp head fixed on the installation support. The lamp head comprises a base and a lamp cover. The base comprises an LED lamp panel and a radiator fixed with the LED lamp panel. The lamp cover is fixed on the surface of the LED lamp panel. The LED tube lamp uses the LED lamp panel as a lighting component to reduce the thickness. Meanwhile, the LED lamp panel further can serve as a component capable of generating torsion with a spring to reduce the thickness of the whole tube lamp and reduce cost.

Description

The LED Down lamp

Technical field

The utility model relates to a kind of LED Down lamp.

Background technology

In lighting technical field, LED (Light Emitting Diode) is progressively substituting existing light source as a kind of emerging light source.Led light source is long except the life-span, power consumption low, the advantage that also have radiationless, empty calory, is easy to reclaim belongs to typical green illumination light source.

In the prior art, often use Down lamp in the decoration field, Down lamp generally is to fix a mount pad at wall or furred ceiling, then the Down lamp lamp holder is installed on the mount pad.This just requires the ceiling furred ceiling that certain thickness is arranged.In addition, existing Down lamp illumination functions is all more single, can only realize the illumination of single brightness, can not satisfy the lighting demand of different occasions.

The utility model content

At the defective that exists in the prior art and deficiency, the purpose of this utility model is to propose the more rational LED Down lamp of a kind of structure.

In order to achieve the above object, the utility model proposes a kind of LED Down lamp, it is characterized in that, comprise mounting bracket and be fixed on lamp holder on the described mounting bracket, described lamp holder comprises base and lampshade, and described base comprises LED lamp plate and the radiator of fixing with described LED lamp plate; Described lampshade is fixed in described LED lamp plate surface.

Preferred as technique scheme, described LED lamp plate is fixed on the described thin heat radiation device by screw, and the torsion spring on the mounting bracket produces torsion by lamp plate.

Preferred as technique scheme also is included as the supply module of described LED lamp plate power supply and the pulse modulation module that is connected with described supply module.

The utility model proposes a kind of LED Down lamp, adopt the LED lamp plate as illuminating device, to reduce the thickness of Down lamp.Simultaneously, this LED lamp plate is also as producing the parts of torsion with torsion spring, reducing the thickness of whole Down lamp, and reduces cost.

Description of drawings

Fig. 1 is the cutaway view of utility model embodiment.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

The utility model preferred embodiment comprises mounting bracket 1 and is fixed on lamp holder on the described mounting bracket 1 that described lamp holder comprises base and lampshade 4 as shown in Figure 1, described base comprise LED lamp plate 31 and with the fixing radiator 32 of described LED lamp plate 31; Described lampshade 4 is fixed in described LED lamp plate 31 surfaces.Like this, can adopt very thin radiator 32, satisfy the thickness that reduces Down lamp under the prerequisite of thermal diffusivity.

As shown in Figure 1, described LED lamp plate 31 is fixed on the described thin heat radiation device 32 by screw, and the torsion spring 5 on the mounting bracket 1 produces torsion by lamp plate.All be that a fixed mechanism is set on base especially in the prior art, and fixing by fixed mechanism and torsion spring 5.Adopt LED lamp plate structure direct and that torsion spring 5 produces torsion to reduce cost.

In order to regulate the brightness of LED lamp plate 31, on the supply module for power supplies such as LED, can connect an impulse modulation (PWM) module, recently realize light modulation to regulate duty.

Certainly; the utility model also can have other embodiment; under the situation that does not deviate from the utility model spirit and essence thereof; the person of ordinary skill in the field works as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of claim of the present utility model.

Claims
