Translucency, optical path at most can only realize 180 ° of planar transmissions in the side for being provided with LED chip, and Integral luminous angle is smaller, shadow
Ring illuminating effect.Meanwhile fluorescent powder is arranged generally on blue-light LED chip and then obtains white light for existing LED light, LED light
Whole colour rendering is lower.Also red fluorescence powder and yellow fluorescent powder by using peak value wavelength promote colour rendering index,
But also resulting in light efficiency simultaneously accordingly reduces.
Utility model content
In order to solve the above technical problems, the purpose of the utility model is to provide a kind of LED lamp panel, light emitting angle is big, has
High color rendering index (CRI) and high photosynthetic efficiency.
The utility model provides a kind of LED lamp panel, comprising: substrate, multiple luminescence units and fluorescent adhesive layer, the substrate are
Cylindrical shell, the multiple luminescence unit are evenly arranged in the outer surface of cylindrical shell, and institute's fluorescent adhesive layer is wrapped in multiple shine
On unit, the luminescence unit include a red light chips and around the red light chips setting four blue chips, it is described
Red light chips and blue chip are concatenated using metal wire.
In the LED lamp panel of the utility model, the fluorescent adhesive layer is mixed with spread powder.
In the LED lamp panel of the utility model, the fluorescent adhesive layer mixes and is additionally provided with transparent adhesive layer between luminescence unit.
In the LED lamp panel of the utility model, the substrate is transparent substrate.
In the LED lamp panel of the utility model, the substrate is equipped with multiple thermal vias.
In the LED lamp panel of the utility model, the luminescence unit include a red light chips and four blue chips, four
A blue chip is distributed in the quadrangle of the red light chips.
In the LED lamp panel of the utility model, the luminescence unit include a red light chips and three blue chips, three
A blue chip is distributed in around the red light chips in Chinese character pin-shaped.
The utility model constitutes the main body of LED lamp panel, it can be achieved that 360 ° of light circumferential transmission by using cylindrical substrate,
The luminescence unit formed by the way that red light chips and blue chip are arranged on substrate, can effectively provide the colour rendering of LED lamp panel,
Feux rouges intrinsic brightness height also will increase the brightness of product, to improve light efficiency.Substrate is made of transparent material, can further improve
Light extraction efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the LED lamp panel of the utility model.
Specific embodiment
As shown in Figure 1, a kind of LED lamp panel of the utility model, comprising: substrate 1, multiple luminescence units 2 and fluorescent adhesive layer
3.The substrate 1 is cylindrical shell, and the multiple 2 yuan of luminous list is evenly arranged in the outer surface of cylindrical shell, institute's fluorescent adhesive layer 3
It is wrapped on multiple luminescence units, the luminescence unit 2 includes a red light chips 21 and is arranged around the red light chips
Multiple blue chips 22, the red light chips 21 and blue chip 22 are concatenated using metal wire.
In the utility model embodiment, since the fluorescent powder in the fluorescent adhesive layer 3 excites meeting by the blue chip 22
Yellow light is issued, and the yellow light cooperation that the blue light and the fluorescent powder that the blue chip 22 issues issue will form white light, in turn
The LED lamp panel can be made to issue white light.Due to the colour rendering index of the blue chip 22 and fluorescent powder cooperation gained white light
It is not high, therefore compensated by the way that the red light chips 21 are arranged, to obtain the light of low color temperature and high-color rendering simultaneously.The feux rouges
The setting quantity of chip 21 is generally far fewer than the setting quantity of the blue chip 22, the blue chip 21 and red light chips 22
Allocation ratio can be specifically arranged according to required obtained light efficiency.
When it is implemented, luminescence unit 2 may include a red light chips 21 and four blue chips 22, four blue chips
22 are distributed in the quadrangle of the red light chips 21.
When it is implemented, luminescence unit 2 may include a red light chips 21 and three blue chips 22, three blue chips
22 are distributed in around the red light chips 21 in Chinese character pin-shaped.
In the LED lamp panel of the utility model, spread powder is mixed in the fluorescent adhesive layer 3.It is mixed into fluorescent adhesive layer 3
A certain proportion of spread powder can effectively improve luminous flux, make light source space colour temperature uniformity.
In the LED lamp panel of the utility model, transparent adhesive layer is additionally provided between the fluorescent adhesive layer 3 and luminescence unit 2.
The distance between fluorescent adhesive layer 3 and luminescence unit 2 can be increased by the way that transparent adhesive layer is arranged, can be reduced since luminescence unit 2 dissipates
The problem that thermally-induced fluorescent powder launching efficiency is low, light efficiency is low, decaying is big.
In the LED lamp panel of the utility model, the substrate 1 is transparent substrate.When it is implemented, it is preferred that only using having
The transparent ceramic material of special optical property is made, while by means of the heat-resisting quantity, oxidative resistance, electricity of transparent ceramic material itself
Insulating properties and resist the performances such as voltage resistance, sufficiently improves the overall quality of the LED lamp panel.Certainly, the substrate 1 also can be used as
Other any suitable materials such as transparent plastic material resistant to high temperature are made.
In the LED lamp panel of the utility model, the substrate 1 is equipped with multiple thermal vias 11.
The above is only the preferred embodiment of the present invention, the thought being not intended to limit the utility model, it is all
Within the spirit and principles of the utility model, it is practical new to should be included in this for any modification, equivalent replacement, improvement and so on
Within the protection scope of type.
