Abstract

The invention discloses an LED lamp, comprising a lamp body, a conductivity and heat conductivity base plate which is fixed on the lamp body, an LED die set fixed on the conductivity and heat conductivity base plate, and a lamp cover which is installed on the front end of the lamp body. The lamp body takes a barrel-shaped appearance, the barrel is recessed inwards to form a cambered surface, and the inner surface of the barrel body is a reflecting mirror face. The invention has the advantages that the space in the lamp body is greatly enlarged by adopting a reflecting mirror face on the lamp body, thus more LED die sets can be installed on the conductivity and heat conductivity base plate, thereby increasing the power of the lamp, and being beneficial for the miniaturization of the lamp. The integrated forming of the reflecting mirror face and the lamp body enables the heat conductivity much smoother, and the whole lamp has a sense of wholeness as a result that the lamp cover is made from nonporous frosted glass or Fresnel radiating sheet, and an LED drive can be built internally and also be built externally.

Description

The LED light fixture
Technical field
The present invention relates to the LED light fixture, be specifically related to a kind of simple for structure and LED light fixture that associative perception is strong.
Background technology
Along with the progressively raising of great power LED light efficiency, the LED light fixture has been widely used in lighting field.As shown in Figure 1, traditional LED light fixture is mainly by forming with lower member: light cover 11, lens 12, LED and aluminium base module 13, radiator 14.
The shortcoming of above structure is:
One, lens 12 take up room greatly, so that can not arrange more LED lamp on aluminium base, thereby have reduced the power of light fixture;
Two, to open a plurality of holes on the light cover 11, damage the associative perception of lamp body;
Three, radiator 14 separates with condenser system (being lens 12), needs more operation just can finish assembling, is prone to assembling deviation, also is unfavorable for distributing of heat.
Summary of the invention
The objective of the invention is to, a kind of simple for structure and LED light fixture that associative perception is strong is provided.
Technical scheme provided by the invention is as follows: construct a kind of LED light fixture, comprise lamp body, be fixed on conductive and heat-conductive substrate on the lamp body, be installed in the some LED modules on the conductive and heat-conductive substrate, the light cover that is installed in the lamp body front end and LED drive, described lamp body has and is inverted tubbiness profile, staving is recessed to form cambered surface inwall (210) downwards with ccontaining conductive and heat-conductive substrate, and the surface of cambered surface inwall is a reflective mirror.
Described reflective mirror and lamp body are one-body molded.
Described light cover is the ground glass or the Fresnel scattering sheet of an atresia.
Described some LED modules are closely arranged on the described conductive and heat-conductive substrate.
The lateral wall of described lamp body is provided with radiating ribs.
Described LED driving can be built in lamp body and also can be placed on lamp body.
The present invention has following advantage: because lamp body is provided with reflective mirror, greatly discharged the space in the lamp body, so just more LED module can be installed on the conductive and heat-conductive substrate, thereby increase the power of light fixture, also be beneficial to the miniaturization that realizes light fixture; And reflective mirror and lamp body are one-body molded, make that the heat conduction is more unobstructed; Simultaneously, also can improve assembling speed; As required, can when processing reflective mirror radian, make it have different beam angles; Light cover is the ground glass or the Fresnel scattering sheet of an atresia, makes whole light fixture have associative perception; LED drive can be built-in also can be external.

The specific embodiment
With reference to Fig. 2, Fig. 3, a kind of LED light fixture is provided, comprise lamp body 21, be fixed on the conductive and heat-conductive substrate 22 on the lamp body 21, the light cover 24 that is installed in the some LED modules 23 on the conductive and heat-conductive substrate 22 and is installed in lamp body 21 front ends, conductive and heat-conductive substrate 22 is fixedlyed connected with lamp body 21 by two screws 221, and the lateral wall of lamp body 21 is provided with radiating ribs 211.
Lamp body 21 has the profile that is tubbiness, staving 21 caves inward and forms the arc reflective mirror, and lamp body 21 can be processed in the mode of turning, also can process with casting or other modes, the surface of cambered surface inwall 210 is formed to reflective mirror, and reflective mirror and lamp body 21 are one-body molded.This reflective mirror can replace the condenser system (being the lens 12 among Fig. 1) of available technology adopting, thereby greatly saved the space in the lamp body 21, so just more LED module 23 can be installed on conductive and heat-conductive substrate 22, LED module 23 can be closely arranged on the conductive and heat-conductive substrate 22 very much, distance between the two LED modules 23 may diminish to 1 millimeter, so just can increase the power of light fixture, also be beneficial to the miniaturization that realizes light fixture; And reflective mirror and lamp body 21 are one-body molded, seamless between the two, make that the heat conduction is more unobstructed; Simultaneously, also can avoid the installation deviation that exists between the reflection shield and lamp body in the prior art, improve assembling speed; As required, can when the processing lamp body, change the reflective mirror radian, make it have different beam angles; Light cover 24 is the ground glass or the Fresnel scattering sheet of the whole shape of an atresia, has changed the way that has the hole that equates with LED module quantity in the prior art on lampshade, makes whole light fixture have associative perception; LED drive can be built-in also can be external.
