Description

A kind of new indoor advertising lamp

Technical field

The utility model relates to technical field of LED illumination, particularly relates to a kind of new indoor advertising lamp.

Background technology

Namely LED illumination is LED lighting, is a kind of semiconducting solid luminescent device.It utilizes solid semiconductor chip as luminescent material, release superfluous energy by carrier generation compound in the semiconductors and cause photo emissions, directly send red, yellow, blue, green light, on this basis, utilize the principle of three primary colours, add fluorescent material, the light of the random color such as red, yellow, blue, green, blue or green, orange, purple, white can be sent.

The LED of LED light source is by three four compounds, and as the semiconductors such as GaAs, GaP, GaAsP are made, its core is PN junction.Therefore, it has the I-V characteristic of general P-N junction, i.e. forward conduction, oppositely cut-off, breakdown characteristics; In addition, under certain condition, it also has the characteristics of luminescence.Under forward voltage, electronics injects P district by N district, and N district is injected by P district in hole; Minority carrier (few son) part entering the other side region and majority carrier (how son) compound and luminous.Luminous compound quantity is larger relative to the ratio of non-luminescent compound quantity, and photo-quantum efficiency is higher.

LED illumination technology may be used on the lighting for various different purposes.Such as, advertising lamp, can divide indoor, outdoor according to use occasion, and outdoor advertising lamp is the size according to outdoor billboard, outdoor advertising is divided into three types: " S " type board---billboard area circle more than 250 square metres, as being distributed in the supersite in large-scale roof, roadside; " B " type board---billboard area between 21 square metres to 249 square metres, as medium-sized billboards such as roof, side, building, columns; " P " type board---billboard area between 1 square metre to 20 square metres, as smaller advertisements boards such as pavement lamp box, lamppost lamp box, telephone booth, Che Ting.But, no matter indoor and outdoor, mainly adopt lamp box printing opacity or these three kinds of technology of light projector, neon light and LED display when advertisement or label, word or pattern can be shown or scroll static pattern and character, adopt LED display can realize upgrading the feature of pattern and character information.

This case it is important to note that for house ads lamp, at present, various indoor exploitation and public service ads lamp box very universal, they not only serve propaganda function, and the effect serving good brightening and beautify the environment; In light emitting source, traditional house ads lamp adopts halogen light source, meanwhile, lacks effective radiator structure, is not easy to easy for installation and rapid heat dissipation, have impact on the service life of light fixture.Therefore, for above aspect, need reasonably to improve prior art.

For achieving the above object, the utility model is by the following technical solutions:

A kind of new indoor advertising lamp, comprise holder, fixed bar, cover, described holder top surface offers installing hole and by being connected with the lower end of fixed bar in this hole, fixed bar upper end wherein connects with the cover of lamp body;

The each other installation in described cover both sides side cover, this cover inside embeds reflection shield and on reflection shield, offers a light source hole installs LED integrated optical source;

The described cover back side fixedly mounts a radiator with heat radiation scale;

Described fixed bar inside is hollow structure and penetrates circuit;

Described holder is made up of U-shaped base and a screw is offered on upper and lower two surfaces of this U-shaped base respectively, and positioning screw, successively through two screws on upper and lower surface, fixedly mounts adjusting nut in positioning screw bottom.

Correspondingly, also following setting can be carried out:

It is inner that fixed muffle is inserted in described fixed bar upper end, and a travel(l)ing rest can be set up in fixed muffle and cover joint;

Described heat radiation scale direction can be laterally or longitudinally, described holder outer setting terminals, in light fixture outside with driving power.

The beneficial effect of new indoor advertising lamp described in the utility model is:

(1) this structure can be arranged on the large scale business places such as exhibition center, exhibition room, exhibition, Display Rack, club, and holder is convenient to be installed on adjustment;

(2) be made up of driving power, holder, fixed bar, radiator, LED integrated optical source, reflection shield, cover etc. by rationally arranging, fixation kit is increased in cover both sides and with fixed bar junction, the lamp body with fixing moulding can be formed, be conducive to realizing easy for installation, energy-conservation, the advantage such as rapid heat dissipation, long service life;

(3) heat sink location is arranged rationally, improves radiating efficiency, protects light fixture;

(4) tradition is adopted halogen light source structure, be improved to and adopt LED integrated light source structure, energy-conserving and environment-protective are energy-conservation, do not need frequent maintenance and replacing.
