Abstract

The utility model provides a LED (light -emitting diode) advertising lamp, the stand of the fixed luminous body that includes the luminous body, be connected with the lamp holder, the bulb of airtight luminous body, the luminous body comprises LED chip, the base plate of installation LED chip, the fluorescent glue that covers on the LED chip, the fluorescent glue is silica gel and phosphor powder mixture, its characterized in that: the base plate appearance is advertising article figure, the area of base plate is greater than the fluorescent glue and covers the area on the base plate, be equipped with heat conductivity gas in the bulb. The utility model provides a pair of LED (light -emitting diode) advertising lamp makes the base plate shape of propaganda material to the base plate leaves abundant heat radiating area, and the bulb inside seal has the thermal diffusivity gaseous, reaches the effect of propaganda and illumination.

Description

A kind of LED advertising lamp

Technical field

The invention relates to a kind of LED advertising lamp, belongs to lighting technical field.

Background technology

Due to heat dissipation equipment and bulb-shaped restriction, current LED solve only lighting problem, LED in terms of advertising is actually rare, how will advertise that product shape is built in bulb and makes the standby well heat radiation of LED lamp, is the key of LED advertising lamp.

Summary of the invention

For the deficiencies in the prior art, the purpose of the invention is to provide a kind of LED advertising lamp, substrate is made the shape of propaganda material, and substrate leaves sufficient area of dissipation, is sealed with thermal diffusivity gas in bulb, reaches the effect of publicity and illumination.

For achieving the above object, the invention is realized by techniques below means:

A kind of LED advertising lamp, the column of the fixing luminous body being connected with lamp holder including luminous body, the bulb of airtight luminous body, described luminous body by LED chip, the substrate of LED chip is installed, the fluorescent glue that is covered in LED chip forms, described fluorescent glue is silica gel and fluorescent material mixture, it is characterized in that: described contour substrate is advertising propaganda material figure, the area that the area of described substrate covers on substrate more than fluorescent glue, is provided with heat conductivity gas in described bulb.

Further:

Described advertising propaganda material figure is brand logo, letter or Chinese character image.

Described advertising propaganda material figure is individual's souvenir or company's propaganda material figure.

Described substrate heat is transferred with photograph.

Described LED chip, fluorescent material are blue chip and yellow fluorescent powder, blue chip and yellowish green pink fluorescent material or blue chip and red fluorescence powder.

Described heat conductivity gas is helium.

Described substrate is transparent or semitransparent ceramic substrate, transparent or semitransparent sapphire substrate.

Described luminophor power is tunable optical power supply.

Described LED chip is several.

The invention provides the benefit that: a kind of LED advertising lamp that the invention provides, and substrate is made the shape of propaganda material, and substrate leaves sufficient area of dissipation, is sealed with thermal diffusivity gas in bulb, reaches the effect of publicity and illumination.

Accompanying drawing explanation

Fig. 1 is luminous body structure schematic diagram, and Fig. 2, Fig. 3 are the schematic diagram of two substrate shape, and Fig. 4, Fig. 5 are two LED advertising lamp appearance schematic diagram.

Detailed description of the invention

Below in conjunction with Figure of description, the invention is further described.

As shown in accompanying drawing 1-5, a kind of LED advertising lamp, the column 7 of fixing luminous body 1 that is connected with lamp holder 6 including luminous body 1, the bulb 5 of airtight luminous body, described luminous body by LED chip 3, the substrate 2 of LED chip 3 is installed, the fluorescent glue 4 that is covered in LED chip 3 forms, described fluorescent glue 4 is silica gel and fluorescent material mixture, it is characterized in that: described substrate 2 profile is advertising propaganda material figure, the area of described substrate 2 covers the area on substrate more than silica gel and phosphor powder mixture 4, is provided with heat conductivity gas in described bulb 5.

Further:

Described substrate 2 thermal transfer has photograph.

Described LED chip 3, fluorescent material are blue chip and yellow fluorescent powder, blue chip and yellowish green pink fluorescent material or blue chip and red fluorescence powder.

Described heat conductivity gas is helium.

Described substrate 2 is transparent or semitransparent ceramic substrate, transparent or semitransparent sapphire substrate.

Described luminous body 1 power supply is tunable optical power supply.

Described LED chip 3 is several.

Detailed process is, the transparent substrate such as glass having heat conduction concurrently is added film plating layer, transparent or semitransparent pottery, sapphire substrates etc. cut into required propaganda material figure, printing technology is utilized to be imprinted on base material by the wire that the LED chip of required arrangement needs, silica gel solid LED chip sequentially being used mixing phosphor powder is scheduled on substrate, LED chip is linked to be loop, the silica gel re-used will cover with side above LED chip with phosphor powder mixture, light assorted required for sending us, it is white light as blue chip adds bloom, it is warm white that blue chip adds yellowish green pink powder, it is pansy that blue chip adds Hydrargyri Oxydum Rubrum.It is important that the area that substrate area need to be coated on substrate more than colloid, can contact with peripheral gas with reservation mass substrate, when LED lights, electric energy is converted into luminous energy and heat energy, light transmission excites phosphor powder to mix out required illumination to all the winds, heat is then diffused rapidly to whole substrate surface via substrate, it is provided that effective heat exchange area, simultaneously, heat energy on chip and substrate by the high thermal conductivity of helium and tubulose stack effect quickly by the torrid zone to tube face, be that heat quickly sheds.

LED chip installs tunable optical power supply, when low current drives, then LED low-light level presents required figure, spread geometry has not been seen too by force due to brightness when high current work, but it is available for illumination to use, due to not enough with the substrate area that fluorescent material mixture covers by silica gel, chip it is brought away from rapidly via the Rapid Circulation heat of high thermal conductivity gas, exchange in outside air via the cell-shell of sealing, chip is placed in one in the ducted body of bulb because extracting air, it is re-filled with helium, without other materials in addition to helium, therefore chip is difficult to aging, relatively Changshou can be maintained to order, also can install lens again in figure front makes figure to project away.

The ultimate principle of the invention, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry; the design is not restricted to the described embodiments; the principle that the design is simply described described in above-described embodiment and description; on the premise of without departing from the design spirit and scope; the invention also has various changes and modifications, in the range of these changes and improvements both fall within claimed the design.The invention claims scope and is defined by appending claims and equivalent thereof.
