Description
Technical field
The invention belongs to technical field of lamps, particularly relate to the LED lamp of a kind of adjustable light-out effect.
Background technology
LED has efficient energy-saving, luminance height, little power consumption, length in service life, light colour purity, stability
The advantage that many conventional light source such as height, high safety, environmental protection are incomparable, is a kind of low-carbon (LC), green, ring
The lighting source protected.The most many places all have begun to popularize and use LED lamp, but existing LED
LED light source within Ju is all hard-wired, it is impossible to regulation LED light source position and direction, therefore,
Can not regulate lamp luminescence angle, can not the light-out effect of flexible modulation light fixture, this kind of LED lamp is the most not
Can be suitably used for needing adjusting light effect, the occasion of multiple luminous intensity distribution is provided.
It addition, LED lamp is big in being also commonly used for short Space, Place, such as passageway, naval vessel, cabin, ship
The places such as type equipment operation room broadly fall into greatly short Space, Place, due to its particularity, and this kind of site requirements lamp
Tool can not have the phenomenon such as dazzle, non-uniform light.
Existing LED lamp generally has following two light distributing method: 1, LED lamp bead becomes spacing arrangement weldering
Being connected on heat sink, heat sink is placed in lamp housing, and Transparent lamp shade is covered on lamp housing；2, by some pasters
LED lamp bead is adhered closely on heat sink, and heat sink is placed in lamp housing, and Transparent lamp shade is covered on lamp housing
On.In first method, owing to LED lamp bead becomes spacing to arrange, light is mapped to the external world through Transparent lamp shade,
So, the light emitted by light fixture is not uniform, but in effect alternately bright, dark, impact illumination effect
Really.Second method then solves the problem that in first method, light is uneven, but, paster LED
Lamp bead power is little, needs to be electrically connected with each other with the form of series connection, so, if wherein lamp bead burn out or
Open circuit, then can cause all lamp bead all can not normal luminous, and, due to the lamp bead used in the method
Quantity is many, and especially for needing the light fixture that luminous intensity is big, needed for it, lamp interior space is big, manufacture work
Skill is complicated, cost is the highest.
Summary of the invention
It is an object of the invention to overcome the defect of prior art, it is provided that adjustable light-out effect and can sending out
Going out the LED lamp of all light, this light fixture can dim in real time and adjustable extent is big.
The present invention is achieved in that the LED lamp of a kind of adjustable light-out effect, including lamp housing, dissipates
Hot plate, LED light source group and Transparent lamp shade, described heat sink is located in described lamp housing, described LED light

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality
Execute example, the present invention is further elaborated.Only should be appreciated that specific embodiment described herein
Only in order to explain the present invention, it is not intended to limit the present invention.
See Fig. 1 and Fig. 3, embodiments provide the LED lamp of a kind of adjustable light-out effect,
Including lamp housing 1, heat sink 2, LED light source group 3 and Transparent lamp shade 4, institute is located at by described heat sink 2
Stating in lamp housing 1, described LED light source group 3 is located on described heat sink 2, and described Transparent lamp shade 4 covers
On described lamp housing 1, referring also to Fig. 4, described heat sink 2 includes a main heat sink 21, both sides heat radiation
Plate 22 and the auxiliary heat dissipation plate 23 that can move along described main heat sink 21 surface normal, described main heat sink
21 is in the form of slot, and side heat sink 22 described in two is hingedly connected to the both sides on edge on described main heat sink 21 cell wall,
It is provided with in described lamp housing 1 for regulating described auxiliary heat dissipation plate 23 and described main heat sink 21 bottom land spacing
Heightening assembly 5, described auxiliary heat dissipation plate 23 is connected with described assembly 5 of heightening and is positioned at described main heat sink
Above 21 bottom lands, the upper surface of side heat sink 22 described in described auxiliary heat dissipation plate 23 and two is equipped with described
LED light source group 3.Owing to side heat sink 22 is articulated with edge on main heat sink 21 cell wall, and auxiliary heat dissipation plate
23 can move along described main heat sink 21 surface normal, it will be understood that by regulation side heat sink 22 phase
For the rotational angle of main heat sink 21 and combine between regulation auxiliary heat dissipation plate 23 and main heat sink 21 bottom land
Away from, i.e. the light-out effect of adjustable luminaire.Such as, dissipate to main respectively when the upper surface of both sides heat sink 22
During hot plate 21 groove outer incline, the light alignment that the LED light source group 3 on both sides heat sink 22 is issued dissipates
Hot plate 2 both sides are penetrated, and the light irradiation angle range finally through Transparent lamp shade 4 is bigger；When dispelling the heat in both sides
LED light source group institute when the upper surface of plate 22 is all parallel with auxiliary heat dissipation plate 23, on both sides heat sink 22
The light ray parallel injection that the light issued and the LED light source group on auxiliary heat dissipation plate 23 are issued,
Light through Transparent lamp shade 4 is more concentrated eventually, photograph is outranged, brightness is higher；When both sides heat sink 22
Upper surface respectively when main heat sink 21 groove is tilted, the LED light source group institute on both sides heat sink 22
Side heat sink 22 direction that the light alignment that issues is relative shoots, so, finally through Transparent lamp shade 4
Light irradiates more to concentrate；Certainly, also can regulate what side heat sink 22 described in two rotated according to specific needs
Angle.This light fixture can carry out real time multi-direction light modulation and adjustable extent is big, can adjust light effect.
