Description

LED light source structure

技术领域Technical field

The invention relates to an LED lighting technology, in particular to an LED light source structure.

背景技术Background technique

led Compared with traditional lighting, lighting has more energy-saving and higher-quality light performance, and is widely preferred in new residential, commercial, and engineering incremental lighting needs, especially integrated LEDs. Luminaire: As a ceiling-embedded luminaire, it has a large heat dissipation area, which makes the LED chip low in temperature and long in life; high light distribution quality and good lighting effect; it has a good decorative effect.

There are a large number of traditional lighting systems for ceiling-mounted downlights. The ceiling-mounted downlight structure mainly includes downlights with and without reflector cups. Figure 1 Shown is a downlight A' with a reflector cup A1', Figure 2 shows a downlight B' without a reflector cup, and the outer edge of the downlight A' and the downlight B' is provided with a decorative ring Q' . If using existing LEDs Lighting replaces traditional lighting, and there is currently no reasonable solution for the following reasons:

If an integrated LED luminaire replaces the recessed downlight of an existing ceiling, the old recessed downlight must be removed and a new LED installed Lamps, which result in a large amount of engineering, high replacement costs, and the renovation of the lighting system involves safe use of electricity, which requires a professional person such as an electrician to complete, ordinary people can not carry out.

If the LED bulb is used to replace the traditional light source in the recessed downlight A' with the reflector cup A1', as shown in Figure 3. As shown, since the existing recessed downlight A' structure with reflective cup A1' is a semi-closed space structure, LED bulb C' The heat generated during the lighting process cannot be dissipated, which causes the temperature inside the recessed downlight to rise, which seriously shortens the life of the LED bulb C', and because of the LED bulb C' Different from the traditional light source light distribution structure, it also reduces the light output efficiency, thus reducing the energy saving effect of installing LED lights.

If the LED directional light is used to replace the traditional light source in the embedded downlight B' without the reflector cup, as shown in Figure 4a, the LED is used. PAR lamp D1' replaces the traditional PAR lamp; or as shown in Figure 4b, replaces the traditional R lamp with LED R lamp D2', due to LED PAR lamp D1' and LED The shape and size of the R lamp D2' is the same as that of the conventional light source. The heat generated by the B' lighting in the recessed downlight cannot be dissipated, which will increase the temperature inside the embedded downlight B' and severely shorten the LED PAR light. The life of D1' and LED R lamp D2', or in order to ensure the life of LED PAR lamp D1' and R lamp D2', LED must be added The cost of chips and heat sinks.

And the replacement of the above LED bulb, LED PAR lamp, LED R lamp does not reach the integrated LED in appearance. The decorative effect of the lamps.

In this regard, the present invention proposes a new LED light source structure that solves the existing LED Lighting replacement ceiling recessed downlights Traditional lighting systems have defects, which are of great significance for accelerating the promotion and application of LED lighting, energy saving and environmental protection.
