Problems solved by technology

[0002] Downlights currently on the market are generally in the form of separate reflectors and different light sources. Most of the light sources are compact energy-saving lamps and incandescent bulbs. Due to the low photoelectric conversion efficiency, incandescent lamps will gradually be eliminated. Some of them use compact energy-saving lamps, but the volume of compact energy-saving lamps is relatively large, and a considerable part of the reflector can only be used with a hole in the side. Downlights without side holes are used in energy-saving lamps above 20W. In the field, its light distribution effect on the downlight will be greatly reduced, resulting in a waste of energy, and this kind of lamp will run outside the downlight after installation, affecting the overall appearance and adding too much difficulty to its various shape designs. And it fundamentally detracts from the aesthetics
[0003] Now there are also lamps on the market that use a single LED as the light source to approximate the light distribution effect of a downlight, but as the power of the LED light source increases, the volume of this lamp will also increase, and when the downlight reaches a certain The power has its limiting factors and cannot be made larger, one of which is its heat dissipation effect. The radiator required for heat dissipation is based on the convenience and practicality of actual use. Under the premise of not affecting the use, its volume cannot do too big

Embodiment 1

[0028] see figure 1 , a method for designing the structure of a heat dissipation downlight with an LED integrated light source according to the present invention, comprising the following steps:

[0029] 1) Prepare a plastic ring 3, LED integrated light source 2, light reflector 5 and radiator 1, place the plastic ring 3 and LED integrated light source 2 inside the light reflector 5, and place the LED integrated light source 2 in the light reflector 5 Between the flat bottom surface and the plastic ring 3, the radiator 1 is placed on the flat bottom surface outside the light reflector 5;

[0030] 2) Prepare two wires to pass through the light reflector 5 and the heat sink 1 and connect to the LED integrated light source 2;

[0031] 3) The plastic ring 3, the LED integrated light source 2, the light reflector 5 and the heat sink 1 are closely pasted and a screw group 4 is prepared to pass through each component to ensure tighter fixation and good contact with each other.

Embodiment 2

[0045] The difference between this embodiment and Embodiment 1 is that the middle of the flat bottom surface of the light reflector 5 is an empty space, and the back of the LED integrated light source 2 is fully coated with plastic heat-conducting material, placed in a hollowed out place and directly connected to the heat sink 1 paste.

Abstract

The invention provides a method for designing a radiating down lamp structure of a light-emitting diode (LED) integrated light source. A plastic ring, the LED integrated light source, a face ring, a clamping ring, a fixing rotary spring, a side lug, a transparent plate, a light ray reflector capable of conducting heat and radiating and a radiator, wherein the LED integrated light source is arranged between the flat bottom surface of the light ray reflector and the plastic ring; the radiator is arranged on a flat bottom surface outside the light ray reflector; and the LED integrated light source can be directly and tightly bonded with the radiator through a hollow part on the middle part of the bottom surface of the light ray reflector. The invention also provides a down lamp for implementing the method. The down lamp has a small and compact size, more reasonable position configuration and light distribution of various fitting parts, higher power and capability of solving radiating problem well.
