Description
Technical field
The present invention relates to the LED lighting field, especially a kind of expansion light source that directly utilizes combines to form the evenly novel large-power LED panel light of illumination behind the lens luminous intensity distribution.
Background technology
Along with deepening continuously of environmental protection theory, the LED panel light is popular in recent years a kind of novel illumination light fixture, and than traditional fluorescent tube, the soft flicker free of its light, and energy-conserving and environment-protective are the optimal selections that replace grid lamp disc.The light efficiency of LED panel light fixture and reliability receive the influence of each side factors such as radiating condition, lamp pearl arrangement mode, power drives efficient, cost; LED panel light in the market adopts the densely arranged mode of low-power LED more; Though the panel light surface brightness is even; And have price advantage with respect to the great power LED panel light, but compare two kinds of light fixtures, the small-power panel light mainly contains 3 deficiencies: one, the small-power panel light needs hundreds of to arrive thousands of low-power LED lamp pearls usually; Caused circuit structure complicated, the reliability of light fixture reduces.Two, because the defective of low-power LED chip and encapsulating structure causes the whole light decay time of small-power very fast, the performance of LED long life characteristics is not obvious.Three, for the higher place of illumination requirement (like subway, market), low-power LED panel light difficulty reaches lighting requirement.So someone has proposed to use the light source of great power LED as panel light, but existing great power LED panel light adopts the side-light type technology more, the output optical efficiency of this light fixture is compared with traditional light fixture, does not have clear superiority.Chinese patent discloses a kind of novel side-light type great power LED panel light, and number of patent application is 200920260338.5, and this side-light type panel light need adopt LGP; If but LGP site design is bad, whole light efficiency can be very poor, and light-emitting area brightness can to occur inconsistent be the too low situation of the uniformity; The LGP volume ratio is bigger in addition, has increased the weight of light source, moreover the cost of LGP is very high; Generally account for more than 25% of whole front panel lamp cost, in addition, the heat radiation of led light source is inhomogeneous; PCB needs highly heat-conductive material, has increased whole cost.One Chinese patent application number is 201010516379.3 just to have mentioned a kind of panel light of great power LED straight-down negative illumination, and this panel light utilizes many great power LEDs to be installed on the aluminium sheet exactly, throws light on after sparing light action through diffuser plate.This type of panel light needs the large-power LED light bead of many quantity, the bad processing of heat dissipation problem, and solving the bigger cost of requirement input on the heat dissipation problem, in addition because lamp pearl number is more, circuit structure is also comparatively complicated, has reduced reliability.
Summary of the invention
The technical problem that the present invention will solve is: a kind of novel large-power LED panel light based on the LED expansion light source is provided, and this LED panel light luminous efficiency and reliability are high, and be easy to maintenance, and the illumination good evenness.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopted is:
A kind of novel large-power LED panel light comprises shell, and the intracavity sidewall of shell is provided with reflecting slant; The intracavity bottom of shell is provided with base plate; Be placed with led light source on the base plate, said led light source is provided with lens, and the top of said lens is provided with light penetrating panel; Said light penetrating panel is fixed on the framework of shell, and the light that said led light source sends penetrates illumination through lens and light penetrating panel.The light that led light source of the present invention sends can form uniform rectangular light spot behind the lens luminous intensity distribution, thereby has substituted traditional LED panel light diffuser plate commonly used, has avoided the loss of diffuser plate to light, has promoted light efficiency, and has improved the uniformity of optics; Said light penetrating panel is fixed on the framework of shell, has played effect dustproof and the protection inner member.
Further as preferred embodiment, said led light source is a high power LED expansion light source.Compare with traditional LED panel light, eliminated the point-like effect greatly, it is luminous to show as light source integral body; Light is evenly soft, has reduced glare effect, simultaneously; Under the prerequisite that guarantees the intensity of illumination demand, significantly reduced the usage quantity of LED lamp pearl, simplified circuit structure; Strengthen the heat-sinking capability of light fixture, improved the reliability and the service life of panel light, reduced cost.
Preferably, said led light source is arranged in array on base plate, can design according to the actual illumination needs and arrange.
Preferably, four sidewalls of the inner chamber of said shell all are provided with intilted reflecting slant, can more light be guided out light fixture.
Preferably, said base plate and reflecting slant are specular aluminium or post reflective membrane or be coated with highly reflective material.
The mentioned expansion light source of the present invention structurally be meant on one group of space very near spot light, its expansion is at the emission light of limited area or volume, refers generally to 1/5 the light source of size greater than optics in the optical design.
The invention has the beneficial effects as follows: the invention provides a kind of novel large-power LED panel light; Through adopting high power LED expansion light source to carry out array arrangement; Utilize secondary optical lens that light has been carried out distribution controls; On target face, formed uniform illumination, the employed diffuser plate of cancellation traditional panel lamp, the light extraction efficiency of light fixture, heat dispersion and reliability are higher.The present invention is simple in structure, has reduced cost, installation, dismounting and easy to maintenance, and the more traditional panel light of LED panel light of the present invention is structurally more light and handy and frivolous.
