Abstract

A red LED lamp bead comprises an LED chip, as well as a radiating substrate, a bracket, silica gel, and pins below the chip, and is characterized in that the chip is a blue chip and is coated with a fluorescent powder layer; and an encapsulation film, actually the red silica gel or a lens, is arranged outside the chip. The indoor lamp adopting the lamp beads can remarkably improve the color rendering index, saves power and causes no luminous flux.

Description

The indoor lamp of a kind of red LED lamp pearl and utilization red LED lamp pearl

[technical field]

The utility model relates to lighting field, relates in particular to the room lighting accessory.

[background technology]

Light source is called color rendering to the colour developing ability of object; Be through with comparison with object appearance color under the reference of colour temperature or the reference light source, under Different Light, because the difference of emission spectrum; Can make color produce tangible aberration; The aberration degree is big more, and light source is more to the color rendering of this look poor, and color rendering index coefficient (Ra) is the evaluation criterion that defines color rendering properties of light source at present.

In the room lighting product, the present domestic encapsulation LED of producer volume production color rendering index can only accomplish 70, and the color rendering index of general room lighting product requirement should reach 80 at least, and manufacturer generally adopts increases the color rendering index that ruddiness improves product.

Employed red-light LED in the room lighting product is directly to have adopted red led chip luminous at present, adopts transparent silica gel or lens to constitute red-light LED again, and a defective of this mode is that its luminous flux is lower, is merely 20-30lm.In order to reach result of use, thus need add 2-5 high-power LED, but so increased power again, energy-conservation inadequately, and color rendering index amplification is limited, causes indoor product color rendering still not ideal enough.

[summary of the invention]

The utility model has proposed a kind of red LED with high light flux to above problem, under the situation of guaranteed output, has realized purpose of energy saving.

The technical scheme of the utility model is: said red LED lamp pearl; Comprise led chip, the heat radiation substrate below chip, support, silica gel, pin; It is characterized in that said chip adopts blue chip, on said chip, is coated with layer of fluorescent powder; Encapsulating film is arranged outside chip, and said encapsulating film is red silica gel or lens.

A kind of indoor lamp of red LED lamp pearl as stated of having used comprises lamp socket, heat-dissipating aluminium plate, lampshade and is fixed on the LED lamp pearl on the heat-dissipating aluminium plate, it is characterized in that, is fixed with said red-light LED lamp pearl and white LED lamp pearl on the heat-dissipating aluminium plate.

Use the LED blue chip to add fluorescent material, like this can excitated fluorescent powder, send the luminous flux of about 120lm, mix red-light LED lens or silica gel, the ruddiness that equally can finally be wanted still but can the too much luminous flux of loss, and luminous flux can be 80-90lm.

The beneficial effect of the utility model is: can significantly improve the color rendering index of indoor lamp, saving power can the loss luminous flux yet.And in general indoor lamp, reach 80 color rendering index, for example 8W needs 5 1W white light LEDs and 3 1W red-light LEDs; Color rendering index can be greater than 80, but luminous flux reduces greatly, uses the red-light LED of big luminous flux; Only need 1, color rendering index can be greater than 85, and economize on electricity has economized 25%.

[description of drawings]

Fig. 1 is the utility model example structure sketch map.

Wherein: 1: anodal pin; 2, anodal pin connecting line; 3, heat radiation substrate; 4, negative pole pin connecting line; 5, negative pole pin; 6, led chip; 7, fluorescent material; 8, encapsulating film; 9, support.

[embodiment]

Referring to accompanying drawing 1; Be the structural representation of single LED lamp pearl, outside led chip 6, be fixed with one deck encapsulating film 8, on chip, be coated with layer of fluorescent powder 7; Under chip heat radiation substrate 3 and support 9; Drawing two pin connecting lines from the chip both sides, is respectively anodal pin connecting line 2 and negative pole pin connecting line 4, is connected respectively to anodal pin 1 and negative pole pin 5.It is whole so to have constituted LED lamp pearl.Said encapsulating film 3 is red LED lens or silica gel.

In the utility model, characteristic just is, in order to obtain powerful red-light LED; So adopted blue led chip; On the led chip of blueness, apply fluorescent material 7, fluorescent material 7 can be excited, and sends the luminous flux of about 120lm; Mix the lens or the silica gel of external red, obtain the utility model and want the ruddiness that is effective.

The best utilization of this lamp pearl just is to use in indoor lamp, can significantly improve the color rendering index of indoor lamp, obtains the indoor light of high-color rendering.

Technological means according to the utility model; Also can obtain high light flux blue led or high light green LED with amount; The blue led of high light flux is that led chip adds fluorescent material and adds the blue light that blue silica gel or lens produce; A kind of high light flux green LED is that led chip adds fluorescent material and adds the green glow that green silica gel or lens produce, and principle thus can be used as the LED of any high light flux color.

A kind of indoor lamp that has adopted said red LED lamp pearl comprises lamp socket, heat-dissipating aluminium plate, lampshade and is fixed on the LED lamp pearl on the heat-dissipating aluminium plate, it is characterized in that, is fixed with said red-light LED lamp pearl and white LED lamp pearl on the heat-dissipating aluminium plate.

The advantage that this programme brought is the color rendering index that can significantly improve indoor lamp, and saving power can the loss luminous flux yet.And in general indoor lamp, reach 80 color rendering index, for example 8W needs 5 1W white light LEDs and 3 1W red-light LEDs; Color rendering index can be greater than 80, but luminous flux reduces greatly, uses the red-light LED of big luminous flux; Only need 1, color rendering index can be greater than 85, and economize on electricity has economized 25%.
