Abstract
The utility model discloses an optical system of an LED wall washer. The optical system comprises a heating panel, wherein an aluminum substrate is arranged on the upper side of the heating panel, a reflecting plate is arranged on the upper side of the aluminum substrate, a plurality of installing holes are arranged on the reflecting plate, and LED chips are arranged in the installing holes; a secondary optical light distribution lens is arranged on the outer side of each of the LED chips; and a plurality of fins in a comb tooth shape used for heat dissipation are arranged on the lower side of the heating plate. The optical system of the LED wall washer has the advantages of being reasonable in design, simple in structure, good in light distribution curves, lighting effect, uniformity and entire heat dissipation effect, long in service life, low in production cost, wide in application range and convenient to popularize and use.
Description
Technical field
The utility model belongs to lighting technical field, relates to a kind of optical system of light fixture, is specifically related to a kind of optical system of LED wall lamp.
Background technology
On building, people can use light fixture that light is projected on the wall of building usually, make building demonstrate fantasy effect at night, and this light fixture that just is used for the building lighting engineering generally is referred to as wall lamp.
Wall lamp is applied in various illuminations place widely at present; In particularly external wall illumination, the building light pass through inside illumination, indoor local lighting, afforest specialized facilities such as Landscape Lighting, billboard lighting, medical culture and throw light on; When the collaborative work of a plurality of LED wall lamp of needs, often need carry out centralized Control.But the LED wall lamp number that need use in some occasion is a lot, thereby arranges very loaded down with trivial details.The main frame of general wall lamp is installed in the lamp body outside in addition, though radiating effect is good like this, has shortcomings such as dustproof, that waterproof effect is relatively poor.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, and a kind of optical system of LED wall lamp is provided, and it is reasonable in design; Simple in structure, have good distribution curve flux, and light efficiency is high; Good uniformity, integral heat sink is effective, long service life; Production cost is low, and the scope of application is extensive, is convenient to promote the use of.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of optical system of LED wall lamp; Comprise heat sink, it is characterized in that: said heat sink upside is provided with aluminium base, and said aluminium base upside is provided with reflecting plate; Said reflecting plate is provided with a plurality of installing holes, is provided with led chip in the said installing hole; Said led chip arranged outside has the secondary optics light-distribution lens; Said heat sink downside is provided with a plurality of broach shape fins that are used to dispel the heat.
Said reflecting plate is the high-purity aluminium sheet.
The utility model compared with prior art has the following advantages:
(1) reasonable optical system design of this LED wall lamp, structure is very simple.
(2) the optical system volume of this LED wall lamp is little, in light weight, is convenient to carrying, arranges.
(3) optical system of this LED wall lamp has good distribution curve flux, and light efficiency is high, good uniformity, can satisfy the illumination optical requirement of wall lamp.
(4) the optical system set inside of this LED wall lamp is useful on the broach shape fin of heat radiation, and integral heat sink is effective, long service life.
(5) the optical system production technology of this LED wall lamp is simple, thereby its production cost is very low, and the scope of application is extensive, is convenient to promote the use of.
Through accompanying drawing and embodiment, the utility model is done further detailed description below.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Description of reference numerals:
The 1-LED chip; 2-secondary optics light-distribution lens; The 3-reflecting plate;
The 4-aluminium base; The 5-heat sink; The 5-1-fin.
The specific embodiment
The optical system of a kind of LED wall lamp as shown in Figure 1 comprises heat sink 5, and said heat sink 5 upsides are provided with aluminium base 4; Said aluminium base 4 upsides are provided with reflecting plate 3; Said reflecting plate 3 is the high-purity aluminium sheet, and the surface reflectivity of high-purity aluminium sheet is high, simultaneously its good heat conduction effect.Said reflecting plate 3 is provided with a plurality of installing holes, is provided with led chip 1 in the said installing hole.
As shown in Figure 1, said led chip 1 arranged outside has secondary optics light-distribution lens 2, and the light that secondary optics light-distribution lens 2 can make led chip 1 distribute penetrates with certain angle of inclination, redistributes light to the appointed area, and result of use is better.
As shown in Figure 1; Said heat sink 5 downsides are provided with a plurality of broach shape fin 5-1 that are used to dispel the heat; Broach shape fin 5-1 can increase the area of dissipation of heat sink 5 greatly, realizes the good heat radiating to led chip 1, has prolonged the service life of wall lamp led chip 1 greatly.
The course of work of the optical system of the utility model LED wall lamp is: at first the optical system with this LED wall lamp installs; Luminous after led chip 1 energized; The light of led chip 1 emission downwards penetrates forward after reflecting through reflecting plate 3; Light forward penetrates with certain angle of inclination behind secondary optics light-distribution lens 2, redistributes light to the appointed area, and result of use is better.The heat that led chip 1 produces when luminous is dispersed in the air through heat sink 5 after aluminium base 4 heat conduction, and heat-conducting effect is very good.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any restriction; Every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of the utility model technical scheme.
Claims (2)
